Abstract
The utility model discloses a mine intrinsically safe type infrared acquisition digital display pressure gauge, which comprises a micro-controller, a sensor, a data storage unit, an infrared transceiving unit, a real-time clock unit, a serial interface communication unit, a liquid crystal display unit and an external input unit, wherein the sensor is a micro-melting pressure sensor; the output end of the sensor is connected with an interface of an A/D (Analogue/Digital) conversion module in the micro-controller; the data storage unit comprises an EEPROM (Electrically Erasable Programmable Read-Only Memory) and a FLASH memory which are in communication connection with the micro-controller respectively; and the external input unit comprises a keystroke switch and an illumination induction module, control output ends of which are connected with the control input end of the micro-controller respectively. The mine intrinsically safe type infrared acquisition digital display pressure gauge disclosed by the utility model has the advantage of being capable of acquiring, displaying or/and storing data in a timed manner by setting times according to requirements, so that the disadvantages of artificial handwritten statistics are effectively solved, and considerable convenience is brought about for mine pressure analysis and the like.
Description
Technical field
The utility model relates to digital display manometer, especially relates 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 utility model purpose 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 utility model can be taked following technical proposals:
The described mine intrinsic safety type of the utility model infrared ray 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 the utility model advantage 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.
