Abstract
The invention relates to a multifunctional carrier module tester. The multifunctional carrier module tester is characterized by being composed of a main control board circuit, a multi-path switching circuit and a carrier interface circuit, wherein the main control board circuit is connected with a multi-path switching chip of the multi-path switching circuit by an I/O (Input/Output) interface; the multi-path switching chip is connected with a carrier chip of the carrier interface circuit by a corresponding pin. The multifunctional carrier module tester can support carrier controller modules of all factories; only the modules need to be replaced aiming at carrier schemes of the different factories, so that the testing working efficiency can be greatly improved and the multifunctional carrier module tester is simple and rapid to operate.
Description
Technical field
The present invention relates to a kind of instrument checkout gear, particularly a kind of multi-functional carrier module tester.
Background technology
Along with the construction of intelligent grid, the intelligent electric meter meeting state's net new standard is is installed and used in a large number, and substantially realizes automatic data logging.In the practical application of intelligent electric meter, a small amount of ammeter can not the fault of automatic data collection be inevitable, and this just needs attendant to carry out malfunction elimination to scene.Because the carrier schemes of different ammeter manufacturer is different, and can not interconnect, attendant often needs to carry palm machine that different manufacturers provides, copy control device and miscellaneous equipment to on-the-spot test carrier module and ammeter whether working properly, and copy control device and the machine of palm program according to ammeter module replacing.This just makes on-site maintenance work become extremely loaded down with trivial details and very easily make mistakes, and have impact on operating efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure simple, the multi-functional carrier module tester of reliable operation.
The object of the present invention is achieved like this: a kind of multi-functional carrier module tester, it is characterized in that it is made up of master control borad circuit, multi-way switch circuit, carrier interface circuit, wherein, master control borad circuit is made up of CPU, memory, I/O interface and keyboard interface, liquid crystal display interface, multi-way switch circuit is made up of variable connector chip, carrier interface circuit is made up of carrier chip, master control borad circuit is connected with the variable connector chip of multi-way switch circuit by I/O interface, and variable connector chip is connected by the carrier chip of respective pin with carrier interface circuit.
Keyboard interface and the liquid crystal display interface of described master control borad circuit are connected to keyboard and liquid crystal touch screen respectively.
Described multi-way switch circuit is also connected with the RS232 interface circuit be made up of Max232 chip.
The invention has the advantages that: support that the carrier wave of all producers copies control device module, also by the supplementary means that infrared and RS485 test as on-the-spot ammeter except carrier wave, support multiple communication protocol (DLT645-1997, DLT645-2007); During on-the-spot test, only need to carry copying of corresponding producer and control device carrier module, that need not carry each producer copies control device and palm machine, for the carrier schemes of different manufacturers, only needs to change module, can greatly improve test job efficiency, and it is simple and efficient to operate.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention;
Fig. 2 is RS232 interface circuit schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present embodiment is load the circuit structure after copying control device module, and it is formed primarily of master control borad, the multi-way switch circuit be made up of variable connector chip U36, the carrier interface circuit that is made up of carrier chip U3.
OutX pin and the OutY pin of the TX0 pin of master control borad circuit I/O serial ports and RX0 pin and carrier chip are connected.
The X2(15 of multi-way switch circuit) pin is RS232 message number (TTL-TXD), X1(14) pin is RS485 message number (RS485-TXD), X0(12) pin is PLC message number (PLC-TXD1), X3(11) pin is infrared signal (IRD-TXD).The input port of master control borad is passed to by chip by different values (00,01,10,11) the gating unlike signal of the chip selection signal end AB of chip.
The X0(12 of multi-way switch circuit), Y0(1) TXD(6 of pin and carrier interface circuit), RXD(7) pin is connected.
4 forceful electric power interface pin L, N(13-16 of carrier interface circuit) connect zero line and the live wire of 220V AC power.
Carrier wave peripheral interface adopts and meets the up-to-date interface standard of national grid, and the carrier wave of accessible different manufacturers copies control device module.
Fig. 2 is RS232 interface circuit, it is made up of Max232 chip U11 and related circuit, the 9(TTL-RXD of Max232 chip), 10(TTL-TXD) the 2(TTL-RXD of pin and multi-way switch circuit), 15(TTL-TXD) pin is connected, TTL-TXD, TTL-RXD signal of input changed into 232 signals and exports from RS232-RXD2, RS232-TXD2.
Master control borad circuit is also connected with keyboard and liquid crystal display screen.
Actual when using, when " passage configuration " or pass through keyboard " channel " when switching communication channel, the chip selection signal AB of variable connector just obtains different value, so just can the different signal of communication of gating.After have selected carrier signal, data to be sent are sent to multi-way switch circuit by serial ports, the carrier chip of carrier interface circuit is sent to again by this circuit, by carrier chip Data import in LN220V AC power, and be sent to intelligent electric meter by alternating current circuit, the data that intelligent electric meter returns, then be sent to master control borad circuit by contrary order, and carry out dissection process by software.
