Abstract
The present utility model discloses a beam tube monitoring serial control device which belongs to the mining detection equipment field. The device comprises an industrial control computer provided with beam tube monitoring management software and a relay drive board. The device is characterized in that the device also comprises a serial communication board, the industrial control computer is connected with the serial communication board through a communication wire, and parallel electric signals of the serial communication board are used for controlling the relay drive board. In the beam tube monitoring serial control device, as the industrial control computer is connected with the serial communication board through the communication wire, serial communication between the industrial control computer and the serial communication board is realized, only three signal lines of a sending data line, a receiving data line and a ground wire are required, the number of the signal lines is reduced, serial communication is provided with relevant data verification rules, reliability of signal transmission is enhanced; the distance between the serial communication board and the relay drive board is greatly reduced as the design is adopted, a finished data connecting line can be selected, workload of installing personnel can be reduced, and cross misconnection of lines can be avoided.
Description
Technical field
The utility model belongs to mine and uses the checkout equipment field, is specifically related to a kind of beam tube monitoring Serial Control device.
Background technology
In recent years, along with the enhancing of mine safety prevention awareness, fire spontaneous combustion beam tube monitoring system is widely used in coal industry gradually; Its principle of work is to be drawn into sensing chamber to the sample gas of each monitoring point, down-hole through beam tube; Under the control of industrial computer management software,, sample gas is detected through switch board automatic switchover gas circuit; Through analysis, reach the purpose of freely burning fire in the prediction mine to each composition gas concentration ratio in the sample gas.
Because the parallel control card is the mature technology in the industrial control field; This control method is simple, directly perceived, is easy to accept, and is widely used in the present fire spontaneous combustion beam tube monitoring system; The industrial computer workstation all is to adopt the parallel signal control mode to the switching of gas circuit; Promptly in industrial computer, insert the parallel control card, introduce the relay drive plate in the switch board to control signal, drive the switching that solenoid valve is accomplished gas circuit by the relay drive plate again through winding displacement.
But in real work, because the quantity of gas circuit that system monitors is big, the winding displacement number is many, causes patching of circuit a little many, situation such as loose contact often occur, causes solenoid valve to be failure to actuate or misoperation; And the workload of wiring is big in the production run, and wrong causes components and parts damage in the circuit easily, even the breaking-up of equipment.
Summary of the invention
The utility model technical matters to be solved provides a kind of beam tube monitoring Serial Control device, and the quantity of control signal wire is few, can improve the reliability of control signal.
For solving the problems of the technologies described above; The technical scheme of the utility model is: design a kind of beam tube monitoring Serial Control device; Comprise industrial computer and relay drive plate that beam tube monitoring management software is installed; It is characterized in that: also comprise the serial communication plate, industrial computer connects serial communication plate, serial communication plate and horizontal electrical signal pilot relay drive plate through connection.
Preferably, also comprise switch board, serial communication plate and relay drive plate all are positioned in the switch board.
Preferably, the casing of switch board is provided with the adaptor of connection, and adaptor connects industrial computer and serial communication plate respectively.
The beneficial effect of the utility model is:
1, because industrial computer connects the serial communication plate through connection; Serial communication plate and horizontal electrical signal pilot relay drive plate; Realize the serial communication of industrial computer and serial communication plate, only needed to send data line, reception data line and three signal wires of ground wire and get final product, reduced the quantity of signal wire; And serial communication has the data check rules, has improved the reliability of signal transmission; So the distance between serial communication plate and the relay drive plate has been shortened in design greatly, can select the finished product data connecting line for use, has reduced the wiring workload of installation personnel, has avoided the situation of circuit intersection wrong.
2, because serial communication plate and relay drive plate all are positioned in the switch board, be convenient to the safety installation of serial communication plate and relay drive plate and the maintenance of system.
3, because the casing of switch board is provided with the adaptor of connection; Adaptor connects industrial computer and serial communication plate respectively; Can make the connection between industrial computer and the serial communication plate realize switching at the switch board place, the user only needs a plug to be connected on that connection gets final product on the switch board when moving switch board; And needn't open switch board, convenient user's use.
Description of drawings
Fig. 1 is the electrical principle block diagram of the utility model.
Mark among the figure: 1, adaptor; 2, switch board; 3, finished product data connecting line.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
As shown in Figure 1; Beam tube monitoring management software is installed among the industrial computer M of the utility model; Serial communication plate D and relay drive plate K next-door neighbour are arranged side by side in switch board 2, and the casing of switch board 2 is provided with the adaptor 1 of connection, and adaptor 1 connects industrial computer M and serial communication plate D respectively; The serial port of industrial computer M connects the adaptor 1 on the switch board 2 through connection; Serial communication plate D has realized the serial communication in industrial computer M and the switch board 2 like this, only needs to send data line TxD, reception data line RxD and three signal wires of ground wire GND and gets final product, and has reduced the quantity of signal wire; And serial communication has the data check rules, has improved the reliability of signal transmission; So the distance between serial communication plate D and the relay drive plate K has been shortened in design greatly, can select finished product data connecting line 3 for use, has reduced the workload of installation personnel, has avoided the situation of circuit intersection wrong.Adaptor 1 has been realized the switching of connection at switch board 2 places, and the user only needs a plug to be connected on that connection gets final product on the adaptor 1, and needn't open switch board 2 when moving switch board 2, has further facilitated user's use.
During use; The control signal of management software is spread out of by the serial ports of industrial computer M; After 1 switching of the adaptor on the switch board 2, pass to serial communication plate D, serial communication plate D converts serial control signal into parallel signal, then pilot relay drive plate K; Realize the switch control of solenoid valve H1-Hn in each gas circuit, accomplish the switch sampling of gas circuit.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
