The communication testing device comprises a housing, and is characterized in that the surface of the housing is provided with a display screen, a keyboard and a communication interface, wherein the interior of the housing is provided with a single-chip microcomputer; the input end of the single-chip microcomputer is electrically connected with the keyboard, and the output end of the single-chip microcomputer is electrically connected with the display screen; and the communication interface is electrically connected with the single-chip microcomputer in an interactive manner. The communication testing device has the characteristics of being convenient to operate, convenient to carry, reliable in performance and the like, and has better effect for communication detection and maintenance of the underground monitoring substation.
Description
Technical field
The present invention relates to a kind of coal mine downhole safety monitoring system, relate in particular to a kind of communication test device for the underground monitoring substation.
Background technology
In the safety monitor and control system, the downhole monitoring substation is being undertaken very important effect, the various instructions that send such as the receiving center station, and control according to command format loopback information or to the down-hole relevant devices; Be responsible for simultaneously gathering the safety in production information of various mine sensors monitorings, after substation monitoring software analyzing and processing, send to ground central station.So outstation requires the independent architectonical of energy, when the ground central station broke down, downhole monitoring work still can be carried out as usual.Therefore whether work, the communication conditions of outstation be normally most important.In case fault has occured outstation, utilize the method for ground host machine inquiry can judge that fault has occured which outstation; But can't find out it is that fault has occured substation, or fault has occured in communication line, has brought difficulty to maintenance, has more brought serious potential safety hazard to safety in production.
Summary of the invention
The present invention is exactly in order to overcome the above problems, and a kind of communication test device for the underground monitoring substation is provided, and this device is easy to carry, and structure is totally-enclosed, is adapted to the down-hole complex environment.
In order to achieve the above object, the invention provides a kind of communication test device for the underground monitoring substation, comprise housing, it is characterized in that: described surface of shell is provided with display screen, keyboard and communication interface, and described enclosure interior is provided with single-chip microcomputer; The input of described single-chip microcomputer is electrically connected with keyboard, and its output is electrically connected with display screen, and described communication interface is electrically connected with single-chip microcomputer is interactive.
The chip of described single-chip microcomputer is AT89C51, its external expansion RAM 6116 chips.
Described keyboard is the sealed type touch keyboard.
Adopt each Monitor Sub-Station of Less of RS485 sata standard bus communication mode and underground work to communicate the communication interface of this device, namely consisting of this communication test device is main frame, and each Monitor Sub-Station of Less is the monitoring system of slave.When fault has occured a certain outstation, utilize the host query of ground central station to judge it is that fault has occured which outstation; Then utilize this communication test device to communicate by letter with this Monitor Sub-Station of Less, immediately find out it is that fault has occured substation, or fault has occured its communication line, judge timely and effectively, brought convenient and swift to maintenance.Get rid of in time potential safety hazard, ensured safety in production.Operating personnel can consult by the function key of keyboard, and in the result who shows the current inquiry of screen display for the failure judgement point.
This device volume is little in addition, and the convenience movement is carried with the staff's.
So this communication test device, have easy to operate, be easy to carry, the characteristics such as dependable performance, in to the communication check of downhole monitoring substation, maintenance, received preferably effect.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic block circuit diagram of the present invention.
Among the figure: 1-housing, 2-display screen, 3-touch keyboard, 4-communication interface, 5-single-chip microcomputer, 6-Monitor Sub-Station of Less.
Embodiment
As shown in Figure 1 and Figure 2, a kind of communication test device for the underground monitoring substation comprises housing 1, and described housing 1 surface is provided with display screen 2, sealed type touch keyboard 3 and communication interface 4, and described housing 1 inside is provided with single-chip microcomputer 5; The input of described single-chip microcomputer 5 is electrically connected with touch keyboard 3, and its output is electrically connected with display screen 2, and described single-chip microcomputer 5 carries out communication by communication interface 4 and Monitor Sub-Station of Less 6.The chip of described single-chip microcomputer 5 is AT89C51, its external expansion RAM 6116 chips.
Adopt each Monitor Sub-Station of Less of RS485 sata standard bus communication mode and underground work to communicate the communication interface of this device, namely consisting of this communication test device is main frame, and each Monitor Sub-Station of Less is the monitoring system of slave.The failure judgement point has brought convenience to maintenance in time, has ensured simultaneously safety in production.
Above-described embodiment is not limited only to protection scope of the present invention, and all are based on basic thought of the present invention and all belonging in protection scope of the present invention of making amendment or change.
