Embodiment
As shown in Figure 1, a sets of data acquisition terminal is respectively installed in each unit, promptly realizes that by the structure of checking meter of supporting the difference in functionality acquisition module with the bus circuit base plate it comprises:
The bus circuit base plate is used for socket and connection platform as each functional module, each binding post is provided, and realizes being connected with outside;
Realize three kinds of functional modules of data acquisition transmission: the model that the data communication module adopts is ST-PPH-101, is responsible for the remote data transmission; The model that multichannel pulse data acquisition module adopts is ST-PPH-801, is responsible for acquisition pulse electric energy meter or pulse water meter, pulse gas meter data; The model that adopts based on the ammeter data acquisition module of RS485 interface is ST-PPH-401, is responsible for gathering the electric energy meter data with 485 interfaces.
Described circuit substrate is equipped with the binding post that connects external pulse electric energy meter, RS485 interface electric energy meter, and bus data cascade terminal; The standard socket that connects external power source is housed on the base plate, and the interface that connects outside mobile data channel communications module; Having 6 standard sockets on the base plate can be for installing three kinds of modules, and wherein first slot can only be installed the ST-PPH-101 module, and three, four, five slots can only be installed the ST-PPH-801 module, and two, six slots can be installed ST-PPH-801 or ST-PPH-401 module; The auxiliary steel plate of installing is housed on the base plate, has screwed hole on the steel plate, after module is inserted on the slot, again with bolted to base plate, can guarantee that module is connected on the base plate reliably, avoided general module+base plate connected mode, adopt base plate riveted joint screw, the stressed difficult problem that comes off easily of screw.After base plate is plugged one or more modules, connect the powered switch power supply again, be installed in the iron case, form a data acquisition terminal, can carry out data acquisition the unit that an ammeter is installed concentratedly.
Three kinds of modules adopt identical ABS plastic shell, leave fixing hole on the shell, are used for bolt module being fastened on base plate; Module is solidified with the perfusion of epoxy branch, only staying a standard socket and base plate pegs graft, avoided electronic component to be exposed to the problem of making moist easily in the air fully, and element is all with the epoxy resin cure of low-shrinkage, also directly improved anti-vibration, the interference of module and all are because the problem of loose contact appears in element because of vibration; Module is guided with having plug-in position being connected of base plate, and the device that has the module of preventing oppositely to peg graft; The indicator light of indicating module operating state is housed on the module, the shinny representation module power supply of this lamp normally and Single Chip Microcomputer (SCM) program wherein normally move.
As shown in Figure 2, terminal (i.e. three kinds of intermodules) connects by the CAN bus carries out data communication, CAN (controller area network) is a controller local area network, it is the serial communication network of distributed control of a kind of effective support and real-time control, it adopts short frame structure, each frame is 8 bytes, and has adopted functions such as position filling, data block coding, CRC check, and the data error rate is extremely low; This terminal adopts the CAN bus to carry out platform district data centralization, can overcome the not high problem of meter reading terminal communication quality in the past, and the data of guaranteeing every ammeter are copied rate and all can be reached 100%.
The CAN bus of all modules is isolated from the outside with photoelectricity coupling chip 6N137, and isolation voltage 2500V guarantees the extraneous overvoltage inside modules circuit of can not breaking; Each module position all has the CAN bus line to communicate on the base plate, after module is inserted on the base plate, and CAN bus automatic switching on; Base plate is provided with CAN bus splicing ear, can be connected with other acquisition terminals easily---cascade.The mode of cascade both can the wired mode of twisted-pair feeder, also can use wireless module to carry out the mode of wireless cascade; Use cascade system, the data in whole district can be concentrated, only an acquisition terminal is installed ST-PPH-101 and ST-PPH-401 module therein, data concentrator as the platform district, other acquisition terminal only need be installed the ST-PPH-801 module, be used for the acquisition pulse ammeter data, 485 ammeter datas are then unified to be connected to ST-PPH-401 module in the concentrator with twisted-pair feeder.
This terminal remote coffret is that mobile communication is counted passage (3G), just as shown in Figure 2, data communication module ST-PPH-101 is realized that by connecting the GPRS remote-transmission module long-range electricity consumption data to all users in the sub-district carry out concentrating in real time making a copy for for GPRS, CDMA.
The burn out detection of ST-PPH-801 pulse collection module application uniqueness described in the utility model is not increasing the single-chip processor i/o resource, need not to have realized the burn out detection of impulse circuit under the condition of extra wiring; The pulse electric energy table of main flow now, the pulsewidth of pulse output is a certain value all, is generally 100mS, 80mS, 60mS etc., loads when big, and pulsewidth will be less than definite value, and the output optocoupler that is to say ammeter is 1 (conducting) time can not surpass this definite value (100mS).
Shown in the burn out detection line circuit figure of Fig. 3, under the cut situation of impulse circuit, the 5V power supply also is cut off to the circuit of triode Q2 base stage, then triode Q2 ends, A point current potential is elevated, triode Q1 is through electronics R1, R2, R5, light lotus root U1 conducting, be that light lotus root U1 conducting single-chip processor i/o mouth is 1, it is after duration of 1 surpassing the pulsewidth definite value that single-chip microcomputer detects the I/O mouth, can send line fault to the center and report to the police, as seen from the figure, impulse circuit by the situation of short circuit under, B point current potential is enhanced and is 5V, can make light lotus root U1 conducting equally through diode D1 and electric ancestral R5, and as seen this testing circuit can detect impulse circuit broken string and two kinds of malfunctions of short circuit.
Utilize identical testing circuit, the pulse collection passage of ST-PPH-801 module also can be realized the unpacking warning function of ammeter box, as long as the sensitive switch of installation and measuring door opening state on ammeter box is guided to ST-PPH-801 to circuit, be connected on the passage through a 10K resistance again and get final product.
