Abstract
The utility model discloses a Bluetooth wireless linkage device for detecting pit-bottom gas concentration, which comprises a nano-micro sensor module, a analog-digital conversion module, a main control module, a Bluetooth linkage information sending module and a display module, and is characterized in that the main control module is connected with the analog-digital conversion module, the Bluetooth linkage information sending module and the display module respectively; the analog-digital conversion module is also connected with the nano-micro sensor module. The nano-micro sensor module is used for highly precisely measuring the pit-bottom gas concentration, detection signals are converted and amplified through the analog-digital conversion module, then the main control module is used for comparing the parameter with the originally set upper limit value, and when the received parameter is greater than the originally set value, the main control module controls the Bluetooth information sending module to send Bluetooth linkage information, and the equipment receiving the linkage information can perform corresponding processing.
Description
Technical field
The utility model relates to a kind of fire damp concentration and detects linkage, and especially fire damp concentration detects the blue teeth wireless linkage.
Background technology
To coal mine gas concentration accurately measure, Real-Time Monitoring and interlock are controlled is to prevent that colliery from gas explosion occurring, guarantee the important measures of personal safety and production safety.At present China is for the equipment of coal mine underground monitoring gas density, also adopts to receive microsensor technology and blue tooth wireless technology.
Summary of the invention
In view of above reason, it is main control module that the utility model adopts single-chip microcomputer, take and receive microsensor as main peripheral cell, have that certainty of measurement is high, simple in structure, reliability is high, explosion-proof, easy to operate, be convenient to the advantages such as maintenance, and can send interlock information by blue teeth wireless.
It is that a kind of fire damp concentration detects the blue teeth wireless linkage that the utility model solves the technical scheme that its technical problem adopts, comprise and receive microsensor module, analog-to-digital conversion module, main control module, bluetooth interlock information sending module, display module, it is characterized in that: main control module is connected with analog-to-digital conversion module, bluetooth interlock information sending module, display module respectively, analog-to-digital conversion module also with receive the microsensor module and be connected.The microsensor module of receiving is carried out the high precision measurement to fire damp concentration, and detection signal is carried out to the signal conversion by analog-to-digital conversion module and amplify, then main control module compares this parameter and original higher limit of setting, when the parameter received during higher than former setting value, main control module is controlled the transmission that the Bluetooth information sending module carries out bluetooth interlock information, and the equipment that receives interlock information can be made the respective handling action.
The beneficial effects of the utility model are, certainty of measurement is high, intuitive display, accurately, can automatically reduce gas density, the advantage such as easy to use and reliable, and can send interlock information by blue teeth wireless, represented that fire damp concentration detects the latest development trend of linkage, has higher practical value.
The accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
The specific embodiment
In Fig. 1, the utility model provides a kind of fire damp concentration to detect the blue teeth wireless linkage, comprise and receive microsensor module 1, analog-to-digital conversion module 2, main control module 3, bluetooth interlock information sending module 4, display module 5, it is characterized in that: main control module 3 is connected with analog-to-digital conversion module 2, bluetooth interlock information sending module 4, display module 5 respectively, analog-to-digital conversion module 2 also with receive microsensor module 1 and be connected.The 1 pair of fire damp concentration of microsensor module of receiving is carried out the high precision measurement, and detection signal is carried out to the signal conversion by analog-to-digital conversion module 2 and amplify, then main control module 3 compares this parameter and original higher limit of setting, when the parameter received during higher than former setting value, main control module 3 is controlled the transmission that Bluetooth information sending module 4 carries out bluetooth interlock information, and the equipment that receives interlock information can be made the respective handling action.
In the measurement of carrying out gas density, what receive 1 output of microsensor module is the signal of 4 ~ 20mA of standard, for adopting two operational amplifiers, the needs that meet subsequent conditioning circuit form the I/V change-over circuit, adopt the RCV420 integrated chip, analog-to-digital conversion module 2 adopts 12 successive approximation type a/d converters, its conversion speed is fast, a conversion time of 12 precision is 25s, switching rate is 40MSPS, there is ternary output in sheet and latch snubber, complete 8 or microprocessor of 16 bit interface, 250 s buses read the time, simple with MPI, be less than ± 1/2LBS of nonlinearity erron or ± 1LBS, send to main control module 3 after conversion, 8090 single-chip microcomputers that main control module 3 adopts Intel Company to produce, can carry out the itinerant monitor system processing to on-the-spot gas monitor point, when exceeding the upper of original setting, concentration parameter prescribes a time limit, main control module 3 directly outputs to the P3 mouth, make bluetooth interlock information sending module 4 send the interlock signal, bluetooth interlock information sending module 4 adopts the serial bluetooth module of ROK 101 008, defer to bluetooth 1.1 standards, it is the communication module of a point-to-multipoint.This module can be simultaneously and 7 bluetooths that are connected in its scope realize transfer of data from equipment.The effective radius of Bluetooth communication is relevant with the power of its output: when power output is 2 classes (2.5mW/4dB), communication range is 15m; The equipment that receives interlock information can be made the respective handling action, and for example ventilation fan and alarm receive this signal and can automatically open, the gas density in diluent air and remind around the staff withdraw.Display module 5 shows related data, display module 5 adopts 44780 LCD that drive, HD44780 (KS0062) is the extensive dot matrix LCD controller of manufacturing by the Low-Power CMOS technology, with the 4bit/8bit microprocessor, be connected, it can make dot matrix LCD show the abundant information such as capital and small letter English alphabet, numbers and symbols, stronger versatility application is arranged simultaneously, easy to use, can just can form a perfect lattice LCD system with a small amount of element, send into relevant data and instruction and can realize required demonstration.
