Abstract
The invention discloses a multifunctional airflow meter fault diagnosis instrument and relates to the technical field of fault detection of coalmine ventilation electronic instruments. The diagnosis instrument is provided with a 220V input interface and connected with a 220V alternating-current (AC) power supply through the 220V input interface; the 220V alternating-current power supply is converted into a direct-current (DC) power supply through an AC-DC power supply module; the DC power supply is used for supplying power to a voltage-current detection module, a frequency changer control circuit, a working voltage/current display module and an output frequency display module; the frequency changer control circuit is connected with a fan output air speed value display module; the working voltage/current display module is connected with a power supply output module; the power supply output module is used for supplying power to an external to-be-detected air speed sensor. The diagnosis instrument has the advantages that various common instruments, tools and toolings are integrated, convenience is brought to detection and alignment calibration of mine airflow meters and air speed sensors, and operation is convenient.
Description
Technical field
The present invention relates to coalmine ventilation electronic device fault detection technique field, specifically a kind of multi-functional wind table failure diagnostic apparatus.
Background technology
The sub-wind table of Coal Electricity is the electronic device of monitoring mining personnel indispensability, air velocity transducer 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 above two kinds of instruments detection, calibration, need wind-tunnel simultaneously, multiple instrument, instrument, frock integrate carries out work, comprises multimeter, D.C. regulated power supply, frequency meter, reometer, wire etc., the use of multiple instrument and conversion, make maintenance become one both to take up space, the work of losing time again.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of multi-functional wind table device 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: multi-functional wind table failure diagnostic apparatus, comprise 220V input interface, 220V alternating current is connected by 220V input interface, 220V alternating current is through the conversion of AC-DC power module, become direct current, power to measure voltage & current module, transducer control circuit, operating voltage/electric current display module and output frequency display module, transducer control circuit connecting fan exports air speed value display module; Operating voltage/electric current display module connects power supply output module; Power supply output module powers to outside air velocity transducer to be measured.
The invention has the beneficial effects as follows: multiple Common Instrument, instrument, frock are rolled into one, achieve the convenience of mining wind table, air velocity transducer detection, calibration work, handled easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, multi-functional wind table failure diagnostic apparatus, 220V alternating current is connected by 220V input interface, 220V alternating current is through the conversion of AC-DC power module, become direct current, power to measure voltage & current module, transducer control circuit, operating voltage/electric current display module and output frequency display module, transducer control circuit connecting fan exports air speed value display module; Operating voltage/electric current display module connects power supply output module; Power supply output module powers to outside air velocity transducer to be measured.
Wherein, measure voltage & current module can detect operating voltage and the electric current of air velocity transducer and blower fan.Blower fan exports the current distinguished and admirable standard speed of air speed value display module display, wind table to be measured is put on the test fixture of micro wind-tunnel, the value that wind table displayed value and blower fan export air speed value display module is compared, see that wind table displayed value is whether correct, export air speed value display module for standard as variant with blower fan and adjustment is carried out to wind table, also the connecting line of air velocity transducer can be connected with diagnostic equipment, then air velocity transducer is put on the test fixture of micro wind-tunnel, after it is working properly, by operating voltage/electric current display module, and output frequency display module, judge that whether the basic parameter of air velocity transducer is normal, pass through transducer control circuit, export different wind speed, with observe air velocity transducer indicating value and above parameters display whether normal, as wind speed indicating value and blower fan, to export air speed value display module variant, air speed value display module displayed value is exported as standard using blower fan, adjustment is carried out to air velocity transducer indicating value.
This diagnostic equipment can realize carrying out calibration, the detection of air velocity transducer frequency output signal to the measuring wind speed displayed value of wind table, air velocity transducer; The detection of air velocity transducer operating voltage, working current; The survey etc. of output frequency signal.
