Description Device for monitoring, controlling and regulating flush lights in a road lighting system The invention relates to a device for monitoring, controlling and regulating flush lights in a road lighting system, in which each flush light has at least one lamp to each of which a transmitter/receiver device having a microcontroller is assigned which lamp is connected via a power supply cable and a router to a control center which has a transmitting/receiving section and a control computer, and from which control commands can be passed to it.
The present invention is now based on the object, stemming from the prior art mentioned above, of providing a device for monitoring, controlling and regulating flush lights in a road lighting system, by means of which device a large number of lamps in flush lights can be controlled, monitored and regulated in a particularly advantageous manner, but nevertheless centrally while dispensing with additional cables, in which case stringent demands are placed on the safety-relevant transmission technique and physical hardware commonality of the components used at remote points.
This object is achieved according to the invention in that the microcontrollers of the flush lights are parts of an LON (locally operating network) which has application-specific components, for example switching and monitoring elements.
In one preferred embodiment of the invention, the microcontroller is designed as a one-chip controller, which leads to considerable savings in terms of the technical/design complexity and the financial cost.
The microcontroller advantageously has an EEPROM, a RAM, three CPUs, a clocking and control block with clock/timer elements, an application input/output block and a communication port, in which the EEPROM, the RAM, the three CPUs, the application input/output block and the communication port are connected to one another by means of an internal address bus and an internal data bus, and the EEPROM, the RAM, the three CPUs, the application input/output block, the communication port and the clocking and control block are connected to one another by means of a timing and control line.
The EEPROM in the microcontroller expediently has 512 bytes, in which case network parameters and application programs can be stored in it.
The three CPUs in the microcontroller should advantageously each be designed as 8-bit CPUs.
In consequence, it is possible to use one of the three CPUs in the microcontroller for application programs.
The two other CPUs in the microcontroller can be used for LONTALK protocol processing, in which case the protocols which can be processed have all seven layers of the reference model in accordance with ISO/OSI.
The application input/output block can advantageously be used as a parallel interface to an external microprocessor having eight data lines and three control lines.
According to one embodiment of the invention, the application input/output block of the microcontroller has a 16-bit loading register, a counting device, a buffer store (latch), a clock source, four 20 mA sink current pins, four a programmable pull-ups and, if required, further elements.
The communication port of the microcontroller advantageously has five network interface pins, by means of which it can be connected to a baseband medium, for example to a twisted two-wire cable, or to an external transceiver.
The microcontroller may have a low-voltage detector and reset circuit, by means of which it is possible to prevent incorrect operation or disturbances in the EEPROM if the applied voltage is less than 4.1 VDL +/- 300 mV tolerance.
If the microcontroller does not have any ROM, it is expedient for it to have an external memory interface. The RAM in the microcontroller may then have advantageous 2048 bytes.
According to a further embodiment of the invention, the microcontroller has a RAM with 1024 or 2048 bytes, and a ROM with 10240 bytes.
Each microcontroller has a unique, permanently stored identification number, by means of which the respective lamp serviceability state can be linked to an address which preferably has 48 bits and for which 6 bytes in the EEPROM can be used.
The microcontroller should expediently have a service pin, so that an effective network device is possible.
Each flush light should have a lamp brightness control circuit, which sets a predetermined lamp current nominal value via a pulse-width modulation element and readjusts the actual value that occurs.
This lamp brightness control circuit is advantageously designed for load-dependent compensation and cable-length compensation for the dropped voltage or the voltage drop.
A switch-mode power supply is advangeously provided which has as the isolating element a toroidal core transformer which interacts with the pulse-width modulation element to determine the transmitted power.
Furthermore, each flush light is expediently provided with an isolating circuit which causes rapid isolation in the event of unacceptable currents, and cancels this isolation after defect rectification, for example by lamp replacement.
A measurement circuit is provided, via which isolation and reconnection can be detected by the microcontroller.
All the lamp functions can advantageously be detected by means of the measurement circuit and can be entered in the microcontroller, in which the lamp actual values can be compared with the lamp nominal values.
If low-voltage halogen lamps are used for the flush lights, it is expedient for each flush light to have a supply circuit, by means of which the lamp current can be matched to the supply voltage.
Each flush light should advantageously have a controller circuit, by means of which a signal can be generated using which the true serviceability state of the lamp, for example a lamp defect, a cable discontinuity or a short circuit, can be reported back.
Each flush light should additionally be provided with a further supply circuit for the microcontroller which is used to ensure that, when faults are present in the lamp circuit, a differential message can be sent to the LON 1.
In an advantageous embodiment of the invention, the microcontroller can be used to report serviceability data about the status of the individual circuits to the control center, which leads to considerable savings in servicing and repair.
In order to simplify servicing and repair further, it is advantageous for the individual flush lights to be connected to the main power supply cable via a detachable connection, in particular via a first plug connection on a cable, which first plug connection is preferably designed as a German domestic standard plug connection and is proof against pressurized water.
The lamp of the flush light may have an internal, second plug connection, which is preferably in the form of a two-pole FAA plug connection, and by means of which the lamp is connected to elements of the flush light connected upstream of it.
The individual flush lights can expediently be lifted out of their seat in the road, and can be disconnected from the main power supply cable by means of the first plug connection.
The association between individual flush lights and flush light groups or flush light chains which can be predetermined, in which case the respective association can be configured via the power supply cable, ensures great variability and adaptability of the road lighting system to different requirements.
The communication on the power supply cable should be capable of being carried out in C-band, in accordance with CENELEC, so that the standards applicable in Europe can be complied with.
The flush lights are connected in parallel with the power supply cable, in an advantageous manner.
In order to simplify the design of the flush lights, the microcontrollers as well as the further switching and monitoring components of the flush light which are connected upstream of the lamp are arranged on a board which is matched to the shape of a housing of the flush light and is mounted in the flush light such that it is resistant to impacts and vibration.
Each flush light advantageously has a module section which contains the microcontroller and the switching and monitoring components which are connected upstream of the lamp of the flush light. This module section facilitates rapid readiness for use again in the event of defects, since it can be replaced in a simple manner.
For this purpose, it is advantageous if the module section of each flush light can be connected by means of the first plug connection, which is proof against pressurized water, to the main power supply cable, and by means of the internal second plug connection to the lamp of the flush light.
In order to suppress interference with the received signal, it is expedient if the module section of each flush light has a metallic, grounded housing.
If the board is designed in the shape of a sickle, it can be arranged around the lamp of the flush light, resulting in the flush light having a flat configuration.
In order to prevent moisture from entering the module section and leading to defects in the flush light, it is advantageous for the module section to be potted such that it is watertight, in which case a cable length is provided for each of the two plug connections.
The module section is advantageously arranged alongside or around the lamp of the flush light, in which case the housing can be matched to the sickle-shaped configuration of the board.
65-Watt lamps may be used for the device described above, provided the light yield is sufficient.
The device according to the invention leads to the capability to operate the flush light in a virtually electrically floating manner with minimal energy consumption, with the energy consumption being very low in the standby mode.
The invention is explained in more detail in the following text using embodiments and with reference to the drawing, in which:
FIG 1 shows an outline illustration of a device according to the invention for monitoring, controlling and regulating flush lights in a road lighting system;
FIG 2 shows a block diagram of a module section and of a lamp of a flush light;
FIG 3 shows the physical arrangement of flush lights, in which case a plurality of associated flush lights are provided;
FIG 4 shows a microcontroller of a flush light for the device according to the invention;
FIG 5 shows an outline illustration of the flush light and of its supply connection to the power cable;
FIG 6 shows a plan view of a module section of the device according to the invention;
FIG 7 shows a view from underneath of the module sectio n illustrated in FIG 6; and FIG 8 shows a plan view of a flush light for the device according to the invention.
A device, which is illustrated in outline form in FIG 1, for monitoring, controlling and regulating flush lights in a road lighting system is broken down into data communication within a LON (local operating network) 1, into control and monitoring by means of a control center, designed as PC 2 in the illustrated exemplary embodiment, and the function of a module section 3 which is illustrated in detail in FIG 2, of which items each flush light 4 has one.
Data communication between the module section 3 of the flush light 4 and the PC 2 which forms the control center is carried out using the LON.
All seven ISO/OSI protocol layers are satisfied, since they are implemented by hardware and software in the microprocessors that are used in the device for monitoring, controlling and regulating flush lights.
It is possible to select various communication media which can be combined and mixed with one another, with the capability to use, for example, optical conductors, twisted two-wire cables (TWP) 5, the power supply network 6 and radio links 7 as communication media.
The transmission method is based on a differential Manchester code with bit synchronization, which can be matched to the respective communication medium. A CSMA method with access priorities provides collision avoidance. Priorities may be allocated for important messages.
The interface between the different communication media used is provided by means of routers 8.
While data communication within commercial buildings preferably uses twisted two-wire cables 5, since a high transmission rate is required there, routers 8 are installed in the area of the low-voltage main distribution boards, by means of which routers 8 data protocols can be coupled to one or more supply networks 6. A feeding arrangement in the form of a star to the distribution board level can thus be implemented for low-voltage networks which are arranged over physically long distances and which may have intermediate medium-voltage transformers.
Transformers 9 to the power supply cable 6, which are provided in the module section 3 of the flush light 4 and are illustrated in FIG 2, as well as the routers 8 operate via the twisted two-wire cables 5 to the LON 1 using C-band, which is approved for Europe, in accordance with CENELEC.
The PC 2 which forms the control center carries out the central configuration, control and monitoring of the lights (which in some circumstances have a number of lamps 10) in the flush lights 4 via the module sections 3. A plurality of PCs 2 may be integrated in the LON at different points without any hierarchy, then operating in a redundant manner and with the capability to monitor one another.
Remote access via modem links or ISDN is possible.
After the arbitrary installation of the module sections 3, the PC 2 is used to configure the association of each module section 3 with the flush light chains 11, 12, 13, 14, 15, 16 illustrated in FIG
3. The appropriate data are loaded in the respective module sections 3 of the flush lights 4, where they are permanently stored. As can be seen from FIG 3, the flush light chains 11 and 13 form a crossover from a lane 17 to a lane 18 arranged alongside, and thus a flush light chain group 11, 13. The flush light chains 12 and 14 form a crossover from the lane 18 to the lane 17, and thus a flush light chain group 12, 14. Since the flush light chains 11, 12, 13, 14 cross over one another, flush lights 4A are provided which are associated with different flush light chains as well as flush light chain groups.
A graphics interface on the PC 2 is used to display the module sections 3, with different colors for the symbols of the module sections 3 being used to indicate different operating states and fault states of the module sections 3, with their connected lamps 10.
A history function makes it possible to detect the time for which all the module sections 3, and the lamps 10 associated with them, have been switched on, and automatically provides servicing information for replacement of luminaires. This is based on the work by the lamps since, when operated below the rated data, the life is extended. All historic and servicing data are stored in a file which can be output to the device from the system. Operating times, defect and selection messages from the module sections 3 can be freely combined in an ordered manner into groups and on the basis of priorities by a PC 2; these items can be processed further, and can be passed on automatically to the servicing organizations, by data traffic with other control console computers.
Using a PC 2, it is possible to determine from each module section 3 the date at which the respective lamp 10 was fitted and the total operating time that has passed on the basis of the working history.
A "service terminal" function is available for replacement of defective module sections 3, by means of which the data from the defective module section 3 are assigned by a PC 2 to the new module section 3, so that the work within the road lighting system is limited exclusively to replacement of the module section 3.
All the module sections 3 can be actuated individually with variable lighting intensities by the PC 2, for test purposes.
Via a PC 2, a traffic management computer can call up freely programmable scenarios relating to the actuation of the flush light chains 11, 12, 13, 14, 15, 16; however, the PC 2 can at the same time act as a traffic management computer. The computer coupling to external systems is produced, for example, by means of an RS 232 interface.
The module section 3, whose block diagram is illustrated in FIG 2, is used for controlling and monitoring in each case one light or lamp 10 in a flush light 4.
The series lamp circuit with the lamp 10 includes an isolating circuit 17 which, if the currents are unacceptably high, ensures rapid disconnection of the lamp circuit section downstream from it and of the lamp 10, which is likewise downstream from it, in the flush light 4. After defect rectification, for example by means of lamp replacement, the isolating circuit 17 connects the lamp circuit again.
The disconnection of the lamp circuit downstream of the isolating circuit 17 is detected by a microcontroller 19 via a measurement circuit 18, since there is an unacceptable error between the actual value and the nominal value, via a connecting 1 ine 20, in the microcontroller 19. This unacceptable error is available, by means of the transformer 9, in the power supply cable 6 and in the LON 1. The same function applies to the return of the lamp circuit after the defect, for example once lamp replacement has been completed.
When low-voltage halogen lamps are used, a supply circuit 21 matches the lamp voltage to the supply voltage. DC isolation can then be provided in such a lamp circuit.
A controller circuit 22 allows the level of the current flowing through the output to be influenced when the lamp circuit is terminated by the lamp 10. The controller circuit 22 receives its manipulated variable via a connecting line 23 from the microcontroller 19, in which the appropriate nominal value is continuously compared with the lamp current actual value. This procedure is used not only to check the lamp current actual value that is fed back, but is also used to report the true serviceability state of the lamp 10 via the transformer 9 to the power supply cable 6 and the LON 1.
The microcontroller 19 contains the permanently stored network address of the module section 3; the lamp serviceability state is provided with this network address there, so that it can be identified in the PC 2 which forms the control center.
A second supply circuit 24, which operates separately from the lamp series circuit formed by the isolating circuit 17, the supply circuit 21, the controller circuit 22 and the measurement circuit 18, is used to supply power to the microcontroller 19 as well as the transformer 9, and thus ensures that, in the event of faults in the lamp series circuit, that is to say if there is a discontinuity in it as well, a differential message is sent to the LON 1 and to the power supply cable 6.
For the microcontroller 19 to acknowledge, via a connecting line 26, the nominal functional operating state which it receives as an instruction via the transformer 9 from the supply network 6 or from the LON
1, for example from the PC 2, it must carry out the instruction, and the true status of the functional data can then be reported, with the address, via a connecting line 25 and the transformer 9 to the LON 1.
The module section 3, whose outline is illustrated in FIG 2, is used in the case of the road lighting system according to the invention as a transmitter/receiver device for the flush light 4, and is connected via the LON l, the router 8 and the twisted two-wire cables 5 to the PC 2, which acts as the control center and has a corresponding transmitting/receiving section and a control computer.
The microcontroller 19 in the module section 3 is designed as a one-chip controller. The microcontroller 19 has an EEPROM 27, a RAM 28, three CPUs 29, 30, 31, a clocking and control block 32, an application input/output block 33 and a communication port 34 which can be connected to the LON via the transformer 9 described in FIG 2.
The EEPROM 27, the RAM 28, the three CPUs 29, 30, 31, the application input/output block and the communication port 34 are connected to one another by means of an internal 16-bit address bus 35 and by means of an internal 8-bit data bus 36.
The EEPROM 27, the RAM 28, the three CPUs 29, 30, 31, the application input/output block 33, the communication port 34 and the clocking and control block 32 are connected to one another by means of a timing and control line 37.
The EEPROM 27 in the microcontroller 19 has at least 512 bytes. Network parameters and application programs can be stored in it.
The three CPUs 29, 30, 31 in the microcontroller 19 are each designed as 8-bit CPUs. The first CPU 29 is used for application programs.
The two other CPUs 30, 31 in the microcontroller 19 are used for LONTALK protocol processing.
The application input/output block 33 of the microcontroller 19 has eleven input/output connections 38 to 45 and 46, 47, 48, of which eight 38 to 45 can be used as data lines and three 46, 47, 48 can be used as control lines, when the application input/output block 33 is used as a parallel interface to an external microprocessor.
The application input/output block 33 has a 16 bit loading register, a counting device, a buffer store (latch), a clock source, four 20 mA sink current pins, four programmable pull-ups and, if required, further elements.
The communication port 34 of the microcontroller 19 has five network interface pins 49, by means of which it can be connected to a baseband medium, for example a twisted two-wire cable, or to an external transceiver.
The clocking and control block 32 has a control block 50 and a clock/timer block 51; the microcontroller may furthermore have a low-voltage detector and reset circuit 52.
The latter prevents incorrect operation or incorrect EEPROM values if the applied voltage is less than a minimum voltage.
The control block 50 in the service block 32 has a reset connection and a service connection.
The clock/timer block 51 has a connection via which standard clock inputs at 20 MHz, 10 MHz, 5 MHz,

The association between individual flush lights and flush light groups or flush light chains which can be predetermined, in which case the respective association can be configured via the power supply cable, ensures great variability and adaptability of the road lighting system to different requirements.
The communication on the power supply cable should be capable of being carried out in C-band, in accordance with CENELEC, so that the standards applicable in Europe can be complied with.
The flush lights are connected in parallel with the power supply cable, in an advantageous manner.
In order to simplify the design of the flush lights, the microcontrollers as well as the further switching and monitoring components of the flush light which are connected upstream of the lamp are arranged on a board which is matched to the shape of a housing of the flush light and is mounted in the flush light such that it is resistant to impacts and vibration.
Each flush light advantageously has a module section which contains the microcontroller and the switching and monitoring components which are connected upstream of the lamp of the flush light. This module section facilitates rapid readiness for use again in the event of defects, since it can be replaced in a simple manner.
For this purpose, it is advantageous if the module section of each flush light can be connected by means of the first plug connection, which is proof against pressurized water, to the main power supply cable, and by means of the internal second plug connection to the lamp of the flush light.
In order to suppress interference with the received signal, it is expedient if the module section of each flush light has a metallic, grounded housing.
If the board is designed in the shape of a sickle, it can be arranged around the lamp of the flush light, resulting in the flush light having a flat configuration.
In order to prevent moisture from entering the module section and leading to defects in the flush light, it is advantageous for the module section to be potted such that it is watertight, in which case a cable length is provided for each of the two plug connections.
The module section is advantageously arranged alongside or around the lamp of the flush light, in which case the housing can be matched to the sickle-shaped configuration of the board.
65-Watt lamps may be used for the device described above, provided the light yield is sufficient.
The device according to the invention leads to the capability to operate the flush light in a virtually electrically floating manner with minimal energy consumption, with the energy consumption being very low in the standby mode.
The invention is explained in more detail in the following text using embodiments and with reference to the drawing, in which:
FIG 1 shows an outline illustration of a device according to the invention for monitoring, controlling and regulating flush lights in a road lighting system;
FIG 2 shows a block diagram of a module section and of a lamp of a flush light;
FIG 3 shows the physical arrangement of flush lights, in which case a plurality of associated flush lights are provided;
FIG 4 shows a microcontroller of a flush light for the device according to the invention;
FIG 5 shows an outline illustration of the flush light and of its supply connection to the power cable;
FIG 6 shows a plan view of a module section of the device according to the invention;
FIG 7 shows a view from underneath of the module sectio n illustrated in FIG 6; and FIG 8 shows a plan view of a flush light for the device according to the invention.
A device, which is illustrated in outline form in FIG 1, for monitoring, controlling and regulating flush lights in a road lighting system is broken down into data communication within a LON (local operating network) 1, into control and monitoring by means of a control center, designed as PC 2 in the illustrated exemplary embodiment, and the function of a module section 3 which is illustrated in detail in FIG 2, of which items each flush light 4 has one.
Data communication between the module section 3 of the flush light 4 and the PC 2 which forms the control center is carried out using the LON.
All seven ISO/OSI protocol layers are satisfied, since they are implemented by hardware and software in the microprocessors that are used in the device for monitoring, controlling and regulating flush lights.
It is possible to select various communication media which can be combined and mixed with one another, with the capability to use, for example, optical conductors, twisted two-wire cables (TWP) 5, the power supply network 6 and radio links 7 as communication media.
The transmission method is based on a differential Manchester code with bit synchronization, which can be matched to the respective communication medium. A CSMA method with access priorities provides collision avoidance. Priorities may be allocated for important messages.
The interface between the different communication media used is provided by means of routers 8.
While data communication within commercial buildings preferably uses twisted two-wire cables 5, since a high transmission rate is required there, routers 8 are installed in the area of the low-voltage main distribution boards, by means of which routers 8 data protocols can be coupled to one or more supply networks 6. A feeding arrangement in the form of a star to the distribution board level can thus be implemented for low-voltage networks which are arranged over physically long distances and which may have intermediate medium-voltage transformers.
Transformers 9 to the power supply cable 6, which are provided in the module section 3 of the flush light 4 and are illustrated in FIG 2, as well as the routers 8 operate via the twisted two-wire cables 5 to the LON 1 using C-band, which is approved for Europe, in accordance with CENELEC.
The PC 2 which forms the control center carries out the central configuration, control and monitoring of the lights (which in some circumstances have a number of lamps 10) in the flush lights 4 via the module sections 3. A plurality of PCs 2 may be integrated in the LON at different points without any hierarchy, then operating in a redundant manner and with the capability to monitor one another.
Remote access via modem links or ISDN is possible.
After the arbitrary installation of the module sections 3, the PC 2 is used to configure the association of each module section 3 with the flush light chains 11, 12, 13, 14, 15, 16 illustrated in FIG
3. The appropriate data are loaded in the respective module sections 3 of the flush lights 4, where they are permanently stored. As can be seen from FIG 3, the flush light chains 11 and 13 form a crossover from a lane 17 to a lane 18 arranged alongside, and thus a flush light chain group 11, 13. The flush light chains 12 and 14 form a crossover from the lane 18 to the lane 17, and thus a flush light chain group 12, 14. Since the flush light chains 11, 12, 13, 14 cross over one another, flush lights 4A are provided which are associated with different flush light chains as well as flush light chain groups.
A graphics interface on the PC 2 is used to display the module sections 3, with different colors for the symbols of the module sections 3 being used to indicate different operating states and fault states of the module sections 3, with their connected lamps 10.
A history function makes it possible to detect the time for which all the module sections 3, and the lamps 10 associated with them, have been switched on, and automatically provides servicing information for replacement of luminaires. This is based on the work by the lamps since, when operated below the rated data, the life is extended. All historic and servicing data are stored in a file which can be output to the device from the system. Operating times, defect and selection messages from the module sections 3 can be freely combined in an ordered manner into groups and on the basis of priorities by a PC 2; these items can be processed further, and can be passed on automatically to the servicing organizations, by data traffic with other control console computers.
Using a PC 2, it is possible to determine from each module section 3 the date at which the respective lamp 10 was fitted and the total operating time that has passed on the basis of the working history.
A "service terminal" function is available for replacement of defective module sections 3, by means of which the data from the defective module section 3 are assigned by a PC 2 to the new module section 3, so that the work within the road lighting system is limited exclusively to replacement of the module section 3.
All the module sections 3 can be actuated individually with variable lighting intensities by the PC 2, for test purposes.
Via a PC 2, a traffic management computer can call up freely programmable scenarios relating to the actuation of the flush light chains 11, 12, 13, 14, 15, 16; however, the PC 2 can at the same time act as a traffic management computer. The computer coupling to external systems is produced, for example, by means of an RS 232 interface.
The module section 3, whose block diagram is illustrated in FIG 2, is used for controlling and monitoring in each case one light or lamp 10 in a flush light 4.
The series lamp circuit with the lamp 10 includes an isolating circuit 17 which, if the currents are unacceptably high, ensures rapid disconnection of the lamp circuit section downstream from it and of the lamp 10, which is likewise downstream from it, in the flush light 4. After defect rectification, for example by means of lamp replacement, the isolating circuit 17 connects the lamp circuit again.
The disconnection of the lamp circuit downstream of the isolating circuit 17 is detected by a microcontroller 19 via a measurement circuit 18, since there is an unacceptable error between the actual value and the nominal value, via a connecting 1 ine 20, in the microcontroller 19. This unacceptable error is available, by means of the transformer 9, in the power supply cable 6 and in the LON 1. The same function applies to the return of the lamp circuit after the defect, for example once lamp replacement has been completed.
When low-voltage halogen lamps are used, a supply circuit 21 matches the lamp voltage to the supply voltage. DC isolation can then be provided in such a lamp circuit.
A controller circuit 22 allows the level of the current flowing through the output to be influenced when the lamp circuit is terminated by the lamp 10. The controller circuit 22 receives its manipulated variable via a connecting line 23 from the microcontroller 19, in which the appropriate nominal value is continuously compared with the lamp current actual value. This procedure is used not only to check the lamp current actual value that is fed back, but is also used to report the true serviceability state of the lamp 10 via the transformer 9 to the power supply cable 6 and the LON 1.
The microcontroller 19 contains the permanently stored network address of the module section 3; the lamp serviceability state is provided with this network address there, so that it can be identified in the PC 2 which forms the control center.
A second supply circuit 24, which operates separately from the lamp series circuit formed by the isolating circuit 17, the supply circuit 21, the controller circuit 22 and the measurement circuit 18, is used to supply power to the microcontroller 19 as well as the transformer 9, and thus ensures that, in the event of faults in the lamp series circuit, that is to say if there is a discontinuity in it as well, a differential message is sent to the LON 1 and to the power supply cable 6.
For the microcontroller 19 to acknowledge, via a connecting line 26, the nominal functional operating state which it receives as an instruction via the transformer 9 from the supply network 6 or from the LON
1, for example from the PC 2, it must carry out the instruction, and the true status of the functional data can then be reported, with the address, via a connecting line 25 and the transformer 9 to the LON 1.
The module section 3, whose outline is illustrated in FIG 2, is used in the case of the road lighting system according to the invention as a transmitter/receiver device for the flush light 4, and is connected via the LON l, the router 8 and the twisted two-wire cables 5 to the PC 2, which acts as the control center and has a corresponding transmitting/receiving section and a control computer.

The application input/output block 33 of the microcontroller 19 has eleven input/output connections 38 to 45 and 46, 47, 48, of which eight 38 to 45 can be used as data lines and three 46, 47, 48 can be used as control lines, when the application input/output block 33 is used as a parallel interface to an external microprocessor.
The application input/output block 33 has a 16 bit loading register, a counting device, a buffer store (latch), a clock source, four 20 mA sink current pins, four programmable pull-ups and, if required, further elements.
The communication port 34 of the microcontroller 19 has five network interface pins 49, by means of which it can be connected to a baseband medium, for example a twisted two-wire cable, or to an external transceiver.
The clocking and control block 32 has a control block 50 and a clock/timer block 51; the microcontroller may furthermore have a low-voltage detector and reset circuit 52.
The latter prevents incorrect operation or incorrect EEPROM values if the applied voltage is less than a minimum voltage.
The control block 50 in the service block 32 has a reset connection and a service connection.
The clock/timer block 51 has a connection via which standard clock inputs at 20 MHz, 10 MHz, 5 MHz,

FIG 5 shows the connection of a flush light 4 to the power supply cable 6. A collar or a branch 54 is provided on the power supply cable 6, and its branching cable section 55 is connected to the module section 3 of the flush light 4 via a first plug connection 56, which is designed as a German domestic standard plug connection and is proof against pressurized water.

Owing to this sickle-shaped configuration of the board 60, the module section 3 can be arranged around the lamp 10, virtually on the same level as the lamp 10 of the flush light 4. This results in the flush light 4 having a configuration which is particularly flat overall, with the consequence that it can be arranged in the lane covering or bitumen region of a road while, in contrast, there is no need for any foundation elements underneath the road for the arrangement of the flush light 4.
The board 60 with the functional elements arranged on it is advantageously provided with a metallic housing 61 which is illustrated, only in principle, by the dashed line in FIG 8.
