Description
Technical field
The utility model relates to a kind of integrated form dc current signal acquisition module.
Background technology
The dc current signal acquisition module generally is used for the straight-flow system insulating monitoring.The acquisition system of existing DC current sensor is that the signal of DC current sensor and working power thereof are connected on D.C. isolation collector or the D.C. isolation logging by the wire line network, its circuit network structure has complexity, the cost height, the shortcoming of construction inconvenience, and the situation that incorrect link causes damaging sensor appears easily in actual the use.
The utility model content
The technical problems to be solved in the utility model provides a kind of integrated form dc current signal acquisition module reliable, simple in structure that connects.
For solving the problems of the technologies described above, the utility model provides following technical scheme: integrated form dc current signal acquisition module comprises: the wiring board support; Be installed in the wiring board on the wiring board support, several serial line interface sockets are housed on the described wiring board; The DC current sensor that has serial line interface; Single-chip microcomputer and A/D modular converter; DC current sensor is inserted on the serial line interface socket of wiring board, and single-chip microcomputer and A/D modular converter link to each other with serial line interface socket on the wiring board.
By above scheme as seen, the utility model integrated form dc current signal acquisition module is realized being connected of DC current sensor and wiring board by using serial line interface/socket, the defective that has overcome that lead connects because circuit network complex structure easy wrong and consumed a large amount of wire rods, and make full use of the connection performance that serial line interface and wiring board are installed, install reliable, simple in structure; Adopt single-chip microcomputer and the A/D modular converter that has serial line interface simultaneously, omitted complicated collection of simulant signal circuit network, the digitizing and the intellectuality of the collection of realization D.C. isolation detection system, conversion, communication.
Description of drawings
Fig. 1 is a STRUCTURE DECOMPOSITION synoptic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
Embodiment
As shown in Figure 1, the utility model integrated form dc current signal acquisition module comprises wiring board support 1, wiring board 2, DC current sensor 3, single-chip microcomputer and A/D modular converter 4.Wherein, several serial line interface sockets 20 and first supply socket 21 are housed on the wiring board 2, the output port 30 of DC current sensor 3 also is a serial line interface, single-chip microcomputer and A/D modular converter 4 be provided with serial line interface 40, output port 41 and with wiring board 2 on first supply socket, 21 corresponding second source sockets 42.In the present embodiment, the signal output port 41 in single-chip microcomputer and the A/D modular converter 4 is the RS485 output port, and in addition, signal output port 41 also can adopt the USB output port.In following examples, single-chip microcomputer and A/D modular converter 4 are directly to be inserted on the serial line interface socket 20 of wiring board 2 by the serial line interface 40 that himself is provided with, in addition, the cable that single-chip microcomputer and A/D modular converter 4 also can be by having serial line interface links to each other with serial line interface socket 20 on the wiring board 2.
During assembling, the wiring board 2 that serial line interface socket 20 is housed is fixed on the wiring board support 1, and DC current sensor 3 and single-chip microcomputer and A/D modular converter 4 serial line interface by separately all directly is inserted on the serial line interface socket 20 of wiring board 2 and can fixes simultaneously.Second source socket 42 on first supply socket 21 on the wiring board 2 and single-chip microcomputer and the A/D modular converter links to each other by lead and realizes conducting.Digital signal realizes and the communication of host computer that by output port 41 outputs of single-chip microcomputer and A/D modular converter 4 working power is imported by plugs and sockets.The utility model acquisition module can be implemented in installation on the power cabinet by wiring board support 1.
As mentioned above, the integrated form dc current signal acquisition module of use serial line interface/socket in use, working power is imported by plugs and sockets, and digital signal is by the output of RS485 or USB port, can realize electric current, resistance signal collection, conversion and with the communication of host computer.The utility model integrated form dc current signal acquisition module has the following advantages: adopts serial line interface not only to peg graft reliably, and omitted complicated collection of simulant signal circuit network, and simple in structure; Single-chip microcomputer and A/D modular converter are directly exported RS485 or usb signal simultaneously, realize synchronous acquisition, transmission and communication, make the D.C. isolation detection system more intelligent and simple.
Certainly, technical conceive of the present utility model is not limited in the foregoing description, can also obtain many different concrete schemes according to design of the present utility model, for example, only carry out function switching signal on single-chip microcomputer and the A/D modular converter, supply socket and signal output port are provided with in the circuit board in addition, export with the power supply input with signal by lead; The quantity of supply socket on the wiring board 2 and serial line interface socket can be different according to monitoring needs, all should be included within the described scope of claim such as these changes and equivalent transformation.
