Abstract
The utility model provides a system for monitoring various harmful gases in a tunnel. The system comprises multiple paths of gas sensors, multiple paths of transmission amplifiers, multiple paths of A/D converters, a CPU central processing unit, an alarm circuit and a liquid crystal display, wherein the multiple paths of transmission amplifiers are used for receiving signals transmitted by the multiple paths of gas sensors, the output ports of the multiple paths of transmission amplifiers are connected with the input ports of the A/D converters, the output ports of the A/D converters are connected with the input port of the CPU, and the output port of the CPU is connected with the alarm circuit and the liquid crystal display respectively. The system can be used for effectively monitoring harmful gases in the tunnel, so that great safety accidents can be avoided.
Description
Technical field:
The utility model belongs to a kind of atmospheric monitoring system, particularly the monitoring system of multiple pernicious gas in a kind of tunnel.
Background technology:
When the coal seam of pressure is opened in Gas Outburst, tunnel, in the short time, have a large amount of Gas, cause gas density in tunnel sharply to raise, if monitor not in time gas density, serious accident likely occurs.And along with the propelling of tunnel excavation work, portable blower also will follow up thereupon, due to air return, in air intake, gas and dust concentration can increase, and all can form security incident.
Summary of the invention;
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and the monitoring system of multiple pernicious gas in a kind of tunnel is provided, and this system can be monitored the pernicious gas in tunnel effectively, avoids occurring great security incident.
As above design, the technical solution of the utility model is: the monitoring system of multiple pernicious gas in a kind of tunnel is characterized in that: comprising that multipath gas sensor, multichannel become send amplifier, multi-channel a/d converter, cpu central processing unit, warning circuit and liquid crystal display; Multichannel becomes send amplifier to receive the signal that the multiple gases sensor is carried, its output port is connected with the input port of A/D converter, the output port of A/D converter is connected with the input port of cpu central processing unit, and the output port of cpu central processing unit is connected with liquid crystal display with warning circuit respectively.
Above-mentioned cpu central processing unit is carried out two-way the connection with communication interface.
The input port of above-mentioned cpu central processing unit is connected with man-machine interface.
The utility model gathers harmful gas concentration in tunnel by the multipath gas sensor, and after this signal is input to and becomes and to send amplifier, through A/D converter, become data signal to be input to cpu central processing unit analog signal conversion, cpu central processing unit is after data analysis and parameter curve analysis contrast, it is presented on display, report to the police simultaneously, thereby avoid occurring great security incident.
The accompanying drawing explanation;
Fig. 1 is theory diagram of the present utility model.
The specific embodiment:
As shown in Figure 1: the monitoring system of multiple pernicious gas in a kind of tunnel comprises that multipath gas sensor, multichannel become to send amplifier, multi-channel a/d converter, cpu central processing unit AT89C55, warning circuit and liquid crystal display.Multichannel becomes send amplifier to receive the signal that the multiple gases sensor is carried, its output port is connected with the input port of A/D converter, the output port of A/D converter is connected with the input port of cpu central processing unit, and the output port of cpu central processing unit is connected with liquid crystal display with warning circuit respectively.
Above-mentioned cpu central processing unit is carried out two-way the connection with communication interface AMG232, and the input port of cpu central processing unit is connected with man-machine interface.
Operating principle of the present utility model is: the output of each road gas sensor the parameter signals such as concentration of the pernicious gas that gathers (as gas), after being entered into and becoming and to send amplifier, through A/D converter, become data signal to be input to cpu central processing unit analog signal conversion, cpu central processing unit is after data analysis and parameter curve analysis contrast, it is presented on display, if harmful gas concentration exceeds standard, report to the police simultaneously, thereby avoid occurring great security incident.
