Abstract
The utility model discloses a multi-channel gas parameter monitor, which comprises a host box (3), wherein a data acquisition card (2) inside the host box (3) is connected with an instrument chassis (1) through a communication cable (5); the instrument chassis (1) is provided with a plurality of channels; each channel is connected with a sensor through a signal cable (6); a power module (10) for supplying a power supply to the sensor and a digital signal module (11) are arranged in the instrument chassis (1); and a sensor signal is converted into a signal which can be identified by the data acquisition card (2) by using the digital signal module (11). The multi-channel gas parameter monitor can be arranged at different positions on equipment as required for monitoring the gas concentration parameter of a certain position on line, data are returned into the instrument, and gas signals are finally recorded and processed through signal processing software in a host computer, so that great convenience is brought to monitoring of gas.
Description
Technical field
The utility model relates to a kind of gas parameter detecting instrument that is used in the mine, particularly a kind of hyperchannel gas parameter monitoring appearance.
Background technology
The principal ingredient of gas is an alkane, and wherein methane accounts for the overwhelming majority, and other has a spot of ethane, propane and butane, generally also contains sulfuretted hydrogen, carbon dioxide, nitrogen and aqueous vapor in addition, and the inert gas of trace, like helium and argon etc.Under the status of criterion, methane to butane exists with gaseous state, and pentane is above to be liquid.Like naked light, promptly " gas " blast takes place in incendivity, and direct threats miner's life security.Therefore, mine work is attached great importance to " gas ".
Therefore, the colliery in order to guarantee safety, needs through the mode of ventilating to the down-hole methane gas in the mine to be discharged in the coal mining activity process, and these methane gas are concentrated and entered atmosphere through well head.Though these methane gas concentration are not high, quantity is very big, is commonly referred to as ventilation air gas.
These methane gas have very high greenhouse effect after entering atmospheric envelope, and the greenhouse effect that methane gas caused are 20 times of carbon dioxide, thereby can cause very big harm to environment.
Utilize if can these methane gas be collected, can reduce destruction on the one hand, also can make full use of the natural resources on the other hand atmospheric environment.The mode of its collection is to realize through the density mode with adsorptive separation of once dividing.In this course, need carry out online detection to the weary general mood body that a plurality of key position passed through of device, judging the wherein concentration of methane gas, and and then the action of control separation equipment.
The utility model content
The utility model technical matters to be solved provides a kind of hyperchannel gas parameter monitoring appearance, and this detector can be monitored the gas density in a plurality of places.
In order to solve above-mentioned technical matters; The technical scheme of the utility model is: a kind of hyperchannel gas parameter monitoring appearance; It comprises mainframe box; The inner data collecting card of said mainframe box is connected with the instrument cabinet through communication cable, and said instrument cabinet has a plurality of passages, and each passage is connected with sensor through signal cable; Also be provided with power module and the digital signal module of supplying with probe power in the said instrument cabinet, said digital signal module converts sensor signal into said data collecting card can identified signal.
Said instrument cabinet has 4 passages.
Said instrument cabinet has 16 passages.
The firedamp sensor of the utility model can be installed in the different position of equipment as required; Gas density parameter to the position is carried out on-line monitoring; And turn back to data in the instrument; And finally through the signal processing software in the host computer Gas Signal is write down and handles, be very easy to monitoring to gas.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is a gas parameter monitoring appearance overall construction drawing.
Fig. 2 is an instrument cabinet inside schematic circuit.
Embodiment
Like Fig. 1, shown in 2; At first insert data collecting card 2 on the motherboard 4 in the mainframe box 3 of computing machine; Data collecting card 2 is connected through the special-purpose jack on the back of special-purpose communication cable 5 and instrument cabinet 1, and each passage has a firedamp sensor 7 to pass through signal cable 6 to be connected with jack on instrument cabinet 1 rear panel in addition.
In instrument cabinet 1 inside, the instrument cabinet can be provided with 4 passages, reaches as high as 16 passages.Instrument cabinet 1 mainly is made up of hyperchannel card extender 9 and multichannel signal converting module; Power module 10 and digital signal module 11 in the signal converting module of each passage, have been comprised; Whole instrument cabinet 1 inside is supplied power by the 220V AC power of outside; Through power lead 12 with alternating current insertion switch power supply 8; Convert alternating current into low-voltage DC through Switching Power Supply 8, and then be diverted on the power module 10 of each passage, low-voltage DC is converted into the working power of the direct current of 3.3V as firedamp sensor 7 through this power module 10.
Gas density signal and the ambient temperature signal gathered of firedamp sensor 7 uploads to digital signal module module 11 through signal cable 6 in addition, gas density signal and ambient temperature signal converted into the Rs232 serial communication signals and the final computing machine that gets into of the standard that data collecting card 2 can accept through this module.
At last Gas Signal is write down and handles by the digital signal processing software in the computing machine.This software can be handled respectively different passages, and the Gas Signal of being gathered is carried out works of treatment such as waveform recording, digital filtering, signal characteristic extraction.
The foregoing description limits the utility model never in any form, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in the protection domain of the utility model.
Claims (3)
1. hyperchannel gas parameter monitoring appearance; It is characterized in that comprising mainframe box (3); The inner data collecting card (2) of said mainframe box (3) is connected with instrument cabinet (1) through communication cable (5); Said instrument cabinet (1) has a plurality of passages; Each passage is connected with sensor through signal cable (6), also is provided with power module (10) and the digital signal module (11) of supplying with probe power in the said instrument cabinet (1), and said digital signal module (11) converts sensor signal into said data collecting card (2) can identified signal.
