Abstract
The invention discloses an intrinsically safe infrared acquisition type digital display pressure gauge for mine. The pressure gauge comprises a microcontroller, a sensor, a data storage unit, an infrared transceiving unit, a real-time clock unit, a serial port communication unit, a liquid crystal display unit and an external input unit; the sensor is a micro fusion pressure sensor, the output end of the sensor is connected with an analog/digital (A/D) conversion module interface in the microcontroller, and the data storage unit comprises an electrically erasable programmable read-only memory (EEPROM) and a FLASH memory which are respectively in communication connection with the microcontroller; and the external input unit comprises a key switch and an illumination sensing module, and the control output end of the external input unit is connected with the control input end of the microcontroller. The pressure gauge has the advantages of setting timed acquisition, display or/and data storage as required, effectively overcoming the defect of manual handwriting statistics and bringing great convenience to mine pressure analysis and the like.
Description
Technical field
The present invention relates to digital display manometer, especially relate to the mine intrinsic safety type infrared ray collection formula digital display manometer that the coal mine fully-mechanized mining working hydraulic system is used.
Background technology
Mining tensimeter mainly is used for showing cavity pressure under the column, judges the force-bearing situation of support through record analysis tensimeter data.At present, the pressure data collecting work mainly relies on artificial write by hand statistics to accomplish, and workload is big, and raw data is preserved inconvenient, gives the pressure history record queries, and fault analysis etc. bring difficulty.
Summary of the invention
The object of the invention is to provide a kind of low cost of manufacture, safe and reliable mine intrinsic safety type infrared ray to gather the formula digital display manometer.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
Mine intrinsic safety type infrared ray of the present invention is gathered the formula digital display manometer, comprises microcontroller, sensor, data storage cell, infrared receiving/transmission unit, real-time clock unit, serial communication unit, liquid crystal display, outside input block; Said sensor is little fusion pressure force transducer, and its output terminal is connected with the inner A/D modular converter interface of microcontroller, and said data storage cell comprises eeprom memory and FLASH storer, is connected with micro-controller communications respectively; Said outside input block comprises keyswitch and illumination induction module, and its control output end is connected with the control input end of microcontroller respectively.
But advantage of the present invention setting-up time timing acquiring, demonstration is as required pressed analysis to wait for the ore deposit and is brought huge convenience or/and the storage data efficiently solve the deficiency that artificial write by hand is added up.Pressure-sensing device adopts little fusion pressure force transducer, and the gaging pressure scope is 0-60MPa, and response frequency is fast, the output signal is big, measuring accuracy is high; Microcontroller (MCU module) employing is low in energy consumption, the mixed type single-chip microcomputer of stable performance, has functions such as A/D conversion, infrared encoding and decoding; The high capacity memory module can be stored the pressure data in the long period, helps pressure history record queries and support force analysis; Serial communication unit, infrared receiving/transmission unit have made things convenient for the transmission and the parameter setting of data.
