Embodiment:
Embodiment one: the electric leakage temperature parameter is surveyed cable network Control work pattern
Referring to Fig. 4, in should using the WWCM module instance, what on-the-spot electric leakage hygrosensor adopted is the MODBUS rtu protocol, and its interface is the RS485 interface.This Communication Control conversion equipment serves as the role of communication dispatch in the wire communication network; Major function is to accomplish the detected value information of gathering a plurality of electric leakage hygrosensors; At the startup GSM interface down that imposes a condition, notify to several pre-set telephone numbers through short message mode.
1, should comprise with middle WWCM hardware capability: 24VDC ± 20% power-supplying circuit comprises two hardware interfaces: 1) RS485 interface; 2) GSM communication interface; Have LED and show two interface communication states, power supply, Watchdog state.Use 4 toggle switchs to set RS485 interface communication speed (38400,19200,9600,2400); Use 1 toggle switch that this module is set and be master mode or listen mode; Have computer online function interface, multiplexing RS485 interface maybe can use the USB download configuration.1 button control networking configuration, 1 button self check is provided with 1 SR.GSM uses general phonecard.The WWCM module is set to master mode through the man-machine setting mouth in the application of Fig. 4.
2, this WWCM software function comprises: the RS485 interface is supported 63 slave addresses data on software, and the data of a corresponding little database storage slave are arranged; The functional mode that under the ModBUS agreement, serves as main frame has automatic network-building addressing configuration feature, 63 slaves of maximum support.The WWCM module is confirmed correctness to the CRC check of MODBUS RTU informational needs.
Multiplexing RS485 interface of computer on-line interface and WWCM module communication are provided with.
The WWCM module comprises the data that a database is used to store slave, and its database is provided with the following information of record:
Use the artificial this locality of computer that data of database is set, the order example is following:
WWCM can support while and 5 mobile phone interaction notes, and its storage setting up procedure is following:
After setting finished, the WWCM module was filled the slave detector on each address of ModBUS host computer polls subordinate, reads the electric leakage temperature parameter, did comparison with the manual work input limit value in the database.Report to the police as surpassing then to produce, notify the setting mobile phone with note or artificial speech mode through GSM.
UNICODE is supported in encapsulation on the GSM communications protocol, so that general mobile phone is accepted Chinese information, protocol conversion module is provided with the client information and detects information combination together, issues the mobile phone client through the note form.The short message interacting of WWCM module and mobile phone has two kinds of situation:
The one, query pattern is supplied with the client and under non-alert if, is inquired about relevant parameter, and example is following:
Sending short message by mobile phone " address+# ", like 01#:
It is following that WWCM replys the inquiry mobile phone: (same note is sent out 3 times continuously.)
Address+" detector "+placement location+", leakage current value: "+leakage current value+", TS1: "+the TS1 value+", TS2: "+TS2+ ", TS3: "+the TS3 value+", TS4: "+the TS4 value.
For example:
" 22 layers of 201 electronic boxs of 02# detector, leakage current value: 55mA, TS1:15 degree, TS2:20 degree, TS3:30 degree, TS4:13 degree "
Another kind is an alarm mode, does not need mobile phone to send inquiry information, when detecting ultra alarming value, all phone numbers is sent 3 times alarming short messages, and form is:
Address+" detector "+placement location+type of alarm+actual value+"＞"+limit value
For example:
" 22 layers of 201 electronic boxs of 02# detector, leakage current is reported to the police, and leaks the building current value: 150mA＞warning limit value 100mA "
" 22 layers of 201 electronic boxs of 02# detector, overtemperature alarm, TS1:120 degree＞warning limit value 100 degree "
Occur simultaneously like a plurality of warnings, send a plurality of notes successively according to the time of fire alarming order.
Embodiment two: pressure parameter is surveyed cable network and is monitored mode of operation
Referring to mistake! Do not find Reference source., similar with last example, should use in the instance, what on-the-spot pressure detector pressure parameter transmission was adopted is the MODBUS rtu protocol, its interface is the RS485 interface.The computer of central control room serves as data acquisition center, that is to say the task of ModBUS host computer communication.Central control room constitutes a complete wired ModBUS communication system with the detector of on-the-spot each address.
Whole work does not produce any influence to the WWCM module to wired system in this example, can hang over communication bus arbitrarily a bit on.The WWCM module is set to listen mode; In use do not send any communication instruction; But when data M odBUS main frame sends the poll instruction, monitor and analyze the information of returning on each slave addresses synchronously, thereby accomplish the task of the detected value information of gathering a plurality of pressure detectors; And, notify to several pre-set telephone numbers through short message mode at the startup GSM interface down that imposes a condition.
This locality of WWCM is provided with, and comprises the database setting, flow process that can reference implementation example one.
Embodiment three: unattended duty ammeter parameters remote is surveyed acquisition system
Referring to Fig. 6, similar with embodiment one, the WWCM module is operated in cable network Control work pattern.The 1#WWCM module is served as the role of communication dispatch in its wire communication network; Major function is to accomplish the detected value information of gathering a plurality of location parameters detectors; Same 2#WWCM module is served as the role of the communication dispatch of another network, accomplishes the detected value information of gathering a plurality of location parameters detectors.And the like, can by a plurality of WWCM modules form separately wired work system network, the WWCM module starts the GSM interface imposing a condition down, notifies to pre-set central control room and several telephone numbers through short message mode.Central control room also can be inquired about in any WWCM of subordinate modular system the parameter current probe value of any arbitrarily under the condition of needs.
This locality of WWCM is provided with, and comprises the database setting, flow process that can reference implementation example one.
