Abstract
The utility model discloses a multifunctional sensor fault diagnosis instrument, which relates to the technical field of sensor fault diagnosis. The diagnosis instrument is provided with a power module, one end of the power module is connected with 200V alternating current, and the alternating current is converted into direct current through the power module and supplies power to a frequency display module, a milliampere current display module and a working voltage/current display module through an over-voltage/over-current protection 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, and the working voltage/current display module is connected with a power output module. The multifunctional sensor fault diagnosis instrument has the advantage that the convenience of maintenance work by the portable instrument is realized by integrating a variety of commonly-used instruments, tools and fixtures without changing a traditional mine-used sensor fault maintenance mode.
Description
Technical field
The utility model relates to the sensor fault diagnosis technical field, and specifically a kind of Multifunction Sensor fault is examined
Disconnected instrument.
Background technology
Mine sensors is that the colliery must be equipped with the necessary component of " coal mine safety monitoring system ".Consumption is large, regularly or irregularly needs repairing, and this is with regard to the corresponding workload that increases the maintainer, to also proposing higher requirement maintenance personal's technical merit, traditional mine sensors detects simultaneously, needs multiple instrument, instrument, frock to integrate and carry out work, 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 utility model provides a kind of Multifunction Sensor failure diagnostic apparatus, and multiple maintenance tool or frock are become one, and has made things convenient for use, and the step that simplifies the operation has simultaneously reduced operation easier.
The utility model is achieved by the following technical solution: a kind of Multifunction Sensor failure diagnostic apparatus, comprise power module, one end of power module connects the 220V alternating current, alternating current is converted to direct current through power module, through overvoltage overcurrent protection module to frequency display module, milliampere electric current display module, operating voltage/working current display module power supply; Frequency display module rate of connections signal input module, milliampere electric current is aobvious
Show that module connects the current signal load module, operating voltage/working current display module connects the power supply output module.
The beneficial effects of the utility model are: under the prerequisite that does not change traditional mine sensors breakdown maintenance mode, multiple Common Instrument, instrument, frock are rolled into one, realized the convenience of portable instrument maintenance job.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings for the below.
Accompanying drawing 1 is the utility model structural representation.
Among the figure: 1, power module, 2, overvoltage/overcurrent protection module, 3, the frequency display module, 4, milliampere electric current display module, 5, operating voltage/electric current display module, 6, the frequency signal load module, 7, the current signal load module, 8, the power supply output module.
Embodiment
As shown in Figure 1, the Multifunction Sensor failure diagnostic apparatus has a power module 1, and alternating current is converted to direct current through power module 1, is whole device each several part power supply through overvoltage/overcurrent protection module 2 again.The analog signals output function of 3 pairs of mine sensors of frequency display module detects, shows.The function of milliampere electric current display module 4 detects, shows for the milliampere current signal output function to mining biography switching value sensor.Frequency signal load module 6 and current signal load module 7 can judge whether the signal output interface of mine sensors is normal.Power supply output module 8 is powered for mine sensors to be detected, shows the running parameter of current mine sensors by operating voltage/working current display module 5 simultaneously.
Wherein, described frequency signal load module 6 adopts standard-frequency meter, the detection of the mining analog sensor of applicable multiple producer.Described current signal load module 7 adopts a milliampere reometer, the detection of applicable multiple producer switching value mine sensors.
In the middle of actual the use, this diagnostic equipment is connected with sensor to be detected by power supply output module 8, to its power supply, after the sensor normal operation, show operating voltage, the working current numerical value of tested sensor by operating voltage/working current display module 5, combined standard voltage, range of current, can judge when front sensor whether normal.The frequency signal output interface of analog sensor is connected with frequency signal load module 6, shows the frequency values of current output at frequency display module 3, 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 7, shows the milliampere current value of current output at milliampere electric current display module 4, so that compare according to certain conversion relation with the displayed value of mine sensors.
Above three kinds of functions are made up, but whether the various functions of detecting sensor is normal.
