All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the existing link network, the link devices usually use a bus mode to establish a communication link, and the communication link deployment is completed in an end-to-end mode, wherein the communication link can be network communication or serial port communication, the traditional mode adopts manual setting of an IP address or manual setting of a dial switch, so that the physical position and the corresponding relation of the communication address of each link device are manually recorded, the field deployment difficulty is also increased sharply along with the gradual increase of the number of the link devices in the link network, and the problem that the conflict easily occurs or the address coding difficulty is high manually when the address is set is solved by adopting a manual field deployment mode.

The roll call signal in this embodiment is used to determine whether the current link device is roll-called by the monitoring device, and the roll-called link device modifies the device address. The link device is then controlled to point the subordinate device, the roll call signal is transmitted to the subordinate device of the link, and the physical location and communication address of the device are correspondingly determined and stored in the monitoring device to complete the address configuration. And so on, each link device in the whole link network is configured with a communication address after being roll-named one by one, thereby completing the determination of the physical position of the whole link and the matching of the communication address.
Specifically, the roll call signal may be triggered by the level change on the internal circuit structure, or by the roll call signal transmitted by the data in the communication link, and the roll call signal may be triggered by the pulse current when the power switch is turned on, for example, the monitoring device sends a high level signal to the first link device connected, the link device determines whether to trigger the default address change instruction according to the received level signal, and the roll call signal identifying circuit 301 determines whether the received signal or data information sent by the upper device is the roll call signal, so as to send the information to the master control circuit.
Because of the cascade link structure of the link network, when a roll call signal is required to be sent to a first device on a link, a monitoring device sends the roll call signal to a link device and drives the link device to carry out current address modification; when the device is not the first device on the link, the link device receives the device roll call signal sent by the cascade upper device, and carries out current address modification.
The roll call signal transmitting circuit 302 is configured to transmit a roll call signal to a subordinate device under control of the master control circuit.
When the device receives the address modification instruction and completes the communication address configuration, the device receives the instruction of sending the roll call signal sent by the main control circuit, and sends the roll call signal to the cascaded downlink device, wherein the roll call signal of the device can also be realized through the level change of the internal circuit, can also be transmitted through the data information transmitted in the signal, can also be transmitted through the pulse current when the switch is turned on, for example, sends a high level signal to the connected downlink device, and the cascaded downlink device determines whether to trigger the default address modification instruction according to the level signal received.
And the data communication circuit 303 is configured to send an address modification instruction issued by the monitoring device to the link device adopting the temporary address after the monitoring device establishes a connection with the link device adopting the temporary address, where the address modification instruction carries a communication address configured by the monitoring device according to the physical location of the link device determined by the number of times of identifying the temporary address.

after the current address of the device is modified into a temporary address, the monitoring device searches the link device which is modified into the temporary address according to the temporary address, and after connection is established with the link device adopting the temporary address, the address modification instruction issued by the monitoring device is received, the address modification instruction carries a communication address configured by the monitoring device according to the physical position of the link device determined by the frequency of identifying the temporary address, in addition, after the device completes the configuration of the communication address according to the address modification instruction, the device communicates with the monitoring device according to the configured communication address, for example, the monitoring device sends a control instruction to the link device with the known communication address, and the link device sends data acquired by the link device to the monitoring device through the data communication circuit 303.
The main control circuit 304 is configured to, when the roll call signal identification circuit identifies a roll call signal, perform a preset logic operation on a current address to obtain a temporary address, receive an address modification instruction from the monitoring device through the data communication circuit, and control the roll call signal sending circuit to send the roll call signal to a subordinate device after completing communication address configuration according to the address modification instruction.
When the roll call signal identification circuit identifies the roll call signal, the current address of the device is modified into a temporary address, the communication address of the device is configured according to the address modification instruction received by the data communication circuit, and the roll call signal transmission circuit is controlled to transmit the roll call signal to the subordinate device.
In each link device, there is a default address set when leaving the factory, when determining that the link device receives the roll call signal, modify the current address into a temporary address, the monitoring device is connected to the link device according to the temporary address, after the current address of the device is modified, because the modified address is the temporary address, the current link device can establish connection with the monitoring device according to the temporary address, after establishing connection with the monitoring device, the monitoring device determines the corresponding communication address of the link device in the link network according to the communication address configured by the times of identifying the temporary address, for example, each device leaving the factory is a (for example, a=255), if the first device identifies that the roll call signal is a high level 1, the first device changes the self address into a temporary address a-1 (254), when the monitoring device is networking, the monitoring device changes the device into a address 1 when determining that the link device is the first device using the link communication universal address, that the device is identified as the device of the first physical location.
Wherein the data communication circuit establishes communication with the monitoring device by at least one of: the network, serial port, controller area network CAN, serial peripheral interface SPI, universal serial bus USB, and two-wire serial bus IIC may be used in the present link device, and other connection establishment methods that CAN be considered by those skilled in the art may be used, which are not limited herein.

after the communication address of the device is modified, the monitoring device establishes communication connection with the link device based on the modified communication address when communicating with the link device next time.
As an optional implementation manner, the link device further comprises a roll call signal judging circuit connected with the main control circuit and used for determining whether the roll call signal identifying circuit identifies the roll call signal.
In this way, the roll call signal determination circuit is used to determine whether the roll call signal is recognized instead of the master control circuit.
As an alternative embodiment, the roll call signal determination circuit is integrated in the same circuit as the roll call signal identification circuit or in the same circuit as the master control circuit.
When the roll call signal judging circuit and the roll call signal identifying circuit are integrated in the same circuit, the roll call judging circuit determines whether to trigger communication address configuration preparation according to the received roll call signal after receiving the roll call signal, and when the communication address configuration preparation is triggered, the communication address configuration preparation is indicated to the main control equipment so as to enable the main control equipment to change the current address;
when the roll call signal judging circuit and the main control circuit are integrated in the same circuit, the roll call judging circuit sends roll call signals to be identified to the main control equipment after receiving the roll call signals, the main control equipment determines whether to trigger communication address configuration preparation according to the received roll call signals, and when the communication address configuration preparation is triggered, the current address is changed.
As an optional implementation manner, the performing a preset logic operation on the current address to obtain a temporary address includes:

As an alternative embodiment, the link device further includes: and the LED display module is used for driving the LED lamp in the LED display module to emit light after the communication address of the device is configured, so that a user of the link device can clearly know whether the link device is configured with the communication address by the monitoring device or not, and the communication address is stored in the address pool.
Wherein the link device may receive and send device roll call signals to the cascaded devices in different ways by changing the internal structure of the link device:
the roll call signal identification circuit is a power switch control circuit, and the roll call signal transmission circuit is a circuit for outputting a power on-off signal to the subordinate device.
In this way, the link device includes a power switch control circuit and a circuit for outputting a power on/off signal to the lower device, receives the power on/off signal sent by the upper device in cascade, and after modifying the communication address of the device, sends the power on/off signal to the lower device in cascade.
Specifically, the power supply breaking device uses a mode of controlling power supply to send a power supply breaking signal, and when the power supply breaking signal sent to the lower-stage equipment is needed, the power supply of the link equipment is broken, at this time, the lower-stage equipment can receive the power supply breaking signal generated by breaking the power supply, and can correspondingly modify the current address into a temporary address and receive an address modification instruction sent by the monitoring equipment, so that the communication address of the link equipment is configured one by switching the power supply of the link equipment.
Fig. 4a is a schematic diagram of a power switch control circuit used in a non-bus mode, and fig. 4b is a schematic diagram of a power switch control circuit used in a bus communication link mode.
The two modes are modes of sending roll call signals by adopting a power switch control circuit, and the difference is that the communication modes of the monitoring equipment and the data communication circuits of all the link equipment are different.
The second mode is that the roll call signal identification circuit is a data communication branch connected with the upper-level equipment, and the roll call signal transmission circuit is a data communication branch for outputting preset data to the lower-level equipment.
Specifically, the roll call signal identification circuit and the roll call signal sending circuit in the link device are circuits which are connected in a data communication mode, rather than switching signals or pulses, and the data communication branch of each link device is only communicated with the data communication branch of the cascade or adjacent link device, and the data communication branch of the cascade link device sends preset data to the cascade lower-level device.
In this case, the roll call signal determining circuit is connected to the master control circuit and is used for determining whether the roll call signal identifying circuit identifies the roll call signal, in this mode, the roll call signal identifying circuit is a data communication branch, and the roll call signal determining circuit and the data communication branch are integrated in the same circuit, where the data communication circuit and the data communication branch may use different cables of one physical interface, or may be divided into two independent interfaces, which is not limited herein.

fig. 5a is a schematic diagram of a principle of using data communication tributary roll call in a one-in-one-out non-bus mode, and fig. 5b is a schematic diagram of a principle of using data communication tributary roll call in a bus mode.
The two modes are modes of sending roll call signals by adopting a data communication circuit, and the difference is that the communication modes of the data communication circuit of the monitoring equipment and each link equipment are different.
In the third mode, the roll call signal identification circuit is a circuit connected to the upper device through a switch, and the roll call signal transmission circuit is a circuit for outputting a switch signal to the lower device, and roll call control and communication address configuration are preferably performed by adopting the mode in this embodiment.
Specifically, the power switch control circuit is used for identifying whether switching value input exists, and the circuit for outputting a switching signal to the lower stage can be simplified into an electronic switch with switching value input, such as an electromagnetic relay, and the like, after the main control equipment completes communication address allocation of the equipment, the electronic switch of the equipment is opened or closed, and the lower stage equipment determines whether to modify the current address into a temporary address according to the opening or closing of the electronic switch.
As shown in fig. 6a, a schematic diagram of the transmitted switch-off signal is shown.
When starting to roll call, the first device sends a roll call signal of default high level 1 to the first link device because no similar link devices are arranged in front, and other link devices are connected to the link device which is not configured with a communication address, so that the roll call signal of default 0 is received by the first device;
each device leaves the factory default address to be A (255), and the first device changes the current address into a temporary address A-1 (254) after receiving the roll call signal level to be high level 1;
when the upper monitoring device is allocated with a networking address, each time the upper monitoring device communicates with a temporary address, for example, the link communication universal address is 254, because the address 254 of the device appears for the first time, the device is changed to address 1 after communication, namely, the device is identified as the device in the first physical position, the communication address is 1 (the IP type is that the communication address is xx.xx.xx.1, and the serial port type is that the communication address is 1);
The monitoring equipment establishes communication with the first equipment, updates a communication address into an address pool of the link equipment, issues a control request to the lower-level equipment of the equipment to which the communication address is allocated to the link equipment, and aims at the notified link equipment to disconnect K1 of the link equipment, wherein the action of disconnecting K1 is communication address allocation preparation action, so that the lower-level equipment can identify a roll call signal of high level 1;
by analogy, a plurality of devices on a link network are individually set to corresponding communication addresses according to the physical locations of the links, and the communication addresses are updated into an address pool.
As an alternative embodiment, a deployment point POD product as shown in fig. 6b is used, the roll call signal identification circuit and the roll call signal transmission circuit are integrated on the POD device, and the roll call control function is implemented by installing the POD product on a link device.
In addition, on the basis of the third mode, the link device integrated with the POD product is used, roll call control can be performed on at least one line of link devices, for example, two-dimensional row-column type matrix network cascading is adopted among PODs, namely, the network connection mode of the link devices is head-to-tail cascading, but the layout position on the physical space is a layout mode of a multi-line matrix mode, if the line where the link device is located needs to be determined, the current link communication mode needs to be determined first, roll call is performed on the link devices of each line by adopting an additional interface link mode, and row position identification of the link device is realized according to the different additional interfaces and the occurrence times of temporary addresses.
Specifically, the roll call signal identification circuit and the roll call signal transmission circuit adopt a first interface protocol, and the data communication circuit adopts a second interface protocol, and are used for transmitting a control instruction issued by the monitoring equipment to the corresponding link equipment which completes the communication address configuration, and uploading data acquired by the link equipment which completes the communication address configuration to the monitoring equipment.

when a link equipment roll call instruction is triggered, roll call signals are sent to an initial A link equipment and a B link equipment which are configured by an address, and as A, B uplink equipment uses two paths of different RS485 buses to roll calls respectively, monitoring equipment can determine the row position of the connected equipment according to the RS485 buses led out by different interfaces;
The monitoring equipment respectively sends roll call signals to A, B uplink equipment through two paths of different RS485 buses, after the link equipment receives the roll call signals, the current address of the equipment is modified to be a temporary address, the monitoring equipment determines the row position of the link equipment according to the RS485 buses, determines the column position of the link equipment according to the times of identifying the temporary address, configures a communication address for the link equipment according to the row position and the column position, sends an address modification instruction carrying the configured communication address to each path of the link equipment adopting the temporary address through the link, and the link equipment configures the local communication address according to the address modification instruction carrying the row and column position.
The fourth mode is that the roll call signal recognition circuit is a circuit in which a switch is connected to the data communication circuit, and the roll call signal transmission circuit is a circuit in which a switch signal is output to the lower-stage device on the data communication circuit.
