Abstract
The invention discloses a sensor fault detection device and relates to the technical field of sensor fault diagnosis. The sensor fault detection device comprises a power supply module, wherein one end of the power supply module is connected with 220V alternating current, and the alternating current is converted into direct current through the power supply module to be respectively supplied for a frequency display module, a milliampere current display module and a working voltage/working current display module; the frequency display module is connected with a frequency signal input module; the milliampere current display module is connected with a current signal input module; the working voltage/working current display module is connected with a power supply output module and an alarm. The sensor fault detection device has the advantage that on the premise of not changing a traditional mine sensor fault maintenance mode, and various commonly-used instruments, tools and tooling are integrated, so that convenience in maintaining a portable instrument is realized.
Description
Technical field
The present invention relates to sensor fault diagnosis technical field, specifically a kind of Transducer fault detection device.
Background technology
Mine sensors is the necessary component that colliery must be equipped with " coal mine safety monitoring system ".Consumption is large, regularly or irregularly needs repairing, and this is the corresponding workload adding maintainer just, also propose higher requirement to the technical merit of maintenance personal, traditional mine sensors detects, and needs multiple instrument, instrument, frock to integrate and carries out work simultaneously, comprise multimeter, D.C. regulated power supply, frequency meter, reometer, wire etc., the use of multiple instrument and conversion, make maintenance become one and both took up space, the work of losing time again.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the invention provides a kind of Multifunction Sensor failure diagnostic apparatus, multiple maintenance tool or frock are become one, facilitate use, simplify the operation step simultaneously, reduces operation easier.
The present invention is achieved through the following technical solutions: a kind of Transducer fault detection device, comprise power module, one end of power module connects 220V alternating current, and alternating current is respectively direct current through the conversion of power module and powers to frequency display module, milliampere electric current display module, operating voltage/working current display module; Frequency display module rate of connections signal input module, milliampere electric current display module connects current signal load module, and operating voltage/working current display module connects power supply output module, and operating voltage/working current display module connects an alarm.
The invention has the beneficial effects as follows: under the prerequisite not changing traditional mine sensors breakdown maintenance mode, multiple Common Instrument, instrument, frock are rolled into one, achieves the convenience of portable instrument maintenance job.
Accompanying drawing explanation
The invention will be further described according to drawings and embodiments below.
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, Transducer fault detection device has a power module, and it is that whole device each several part is powered that alternating current is converted to direct current through power module.The analog signals output function of frequency display module to mine sensors detects, shows.The function of milliampere electric current display module is detect the milliampere current signal output function of mining biography switching value sensor, show.Frequency signal load module and current signal load module can judge that whether the signal output interface of mine sensors is normal.Power supply output module is that mine sensors to be detected is powered, and is shown the running parameter of current mine sensors by operating voltage/working current display module simultaneously.Operating voltage/working current display module connects an alarm.
Wherein, described frequency signal load module adopts standard-frequency meter, the detection of the mining analog sensor of applicable multiple producer.Described current signal load module adopts milliampere reometer, the detection of applicable multiple producer switching value mine sensors.
In the middle of actual use, this diagnostic equipment is connected with sensor to be detected by power supply output module, to its power supply, after normal operation of sensor, operating voltage, the working current numerical value of tested sensor is shown by operating voltage/working current display module, combined standard voltage, range of current, can judge that whether current sensor is normal.The frequency signal output interface of analog sensor is connected with frequency signal load module, frequency display module shows the frequency values of current output, so that compare according to certain conversion relation with the displayed value of mine sensors.The milliampere current signal output interface of Boolean value output sensor is connected with current signal load module, shows the milliampere current value of current output at milliampere electric current display module, so that compare according to certain conversion relation with the displayed value of mine sensors.
Above three kinds of functions are combined, can the various functions of detecting sensor whether normal.
