Abstract
The utility model discloses a vehicle-mounted gas monitoring system, which overcomes the defects that a traditional gas monitoring system can only monitor gas concentration of fixed points in a tunnel, and simultaneously solves the difficulties caused by strict explosion-proof treatment for various large vehicle devices in the gas tunnel construction. The vehicle-mounted gas monitoring system comprises a control substation which is connected with a computer maintenance system through a data interface, and a first sensor, a second sensor, a power-off control device, an electronic flame-out device and an alarm which are respectively connected with the control substation through data lines, wherein the control substation is arranged in a cab of an engineering vehicle, and the first sensor and the second sensor are respectively arranged at ventilated places of the top of the cab and the ventilated places of the bottom of the vehicle. The vehicle-mounted gas monitoring system is quick to install and simple and convenient to maintain, can be installed only at a construction maintenance site, and is stable and reliable to operate, and the dynamic characteristics of vehicles can not be changed.
Description
Technical field
The utility model relates to a kind of gas monitoring system, is specifically related to a kind of vehicle-mounted gas monitoring system.
Background technology
In the work progress of gas tunnel, for guaranteeing safety, need in the tunnel, to install gas monitoring system, but gas distributed pole in the tunnel is inhomogeneous, gas monitoring system institute data monitored can only be represented the gas density of position, monitoring point, can not represent the whole piece tunnel, thereby dangerous situation can not in time forecast when taking place, and there are many difficulties in various oversize vehicle equipment because of the explosion-proof processing of carrying out strictness in the gas tunnel construction.Because the restriction of multiple condition, the job site often needs many large-scale vehicle arrangements, as excavator, loader, transportation locomotive etc., and these equipment shuttle back and forth and are to and from the whole piece tunnel, integrating tunnel practice of construction situation, study a kind of simple and direct light instant concentration of gas that vehicle-mounted gas monitoring system can monitor the vehicle loca that is suitable for, in time forecast and handle dangerous situation, avoid simultaneously these large-scale haulage devices are carried out strict explosion-proof processing and increase cost.
Summary of the invention
The utility model is can not in time forecast the dangerous situation that gas density caused beyond the monitoring point in order to solve in the gas tunnel work progress fixing gas monitoring system, and various oversize vehicle plant equipment have difficulties because of carrying out strict explosion-proof processing in the gas tunnel work progress, are suitable for vehicle-mounted gas monitoring system and studied a cover.
The utility model is achieved through the following technical solutions:
A kind of vehicle-mounted gas monitoring system, comprise the control substation that is connected with the computer maintenance system by data-interface, and by data wire respectively with control the substation first sensor, second sensor, power-down control device, electronics blanket, the alarm that are connected, the control substation is installed in the engineering truck driver's cabin, and the first sensor and second sensor are installed in driver's cabin top portion ventilation place and ventilation, car bottom respectively.
Described control substation also can be installed in machinery bottom or sidepiece or be installed in driver's cabin and the junction, compartment.
Described first sensor, second sensor can be firedamp sensor, carbon monoxide transducer or carbon dioxide sensor.
Described alarm is an audible-visual annunciator.
During system works, as shown in Figure 2, the environment gas density rises gradually, and when reaching the concentration of comparison danger, the sensor that is installed in driver's cabin top and vehicle bottom can signal to the control substation, the control substation sends alarm signal to alarm again, alarm sends sound and light alarm, after driver and crew hear or see alarm signal, stops operation immediately, find out cause and clear after go operation again, can realize the effect of dangerous advanced processing.If gas density rises very fast or during the on-the-spot unmanned of construction machinery, the environment gas density reaches the higher risk limit value, control substation this moment and send control signal to flame-out controller of the oil-break of machinery and power-supply controller of electric once more, machinery is quit work automatically and close general supply, realize locking.
The installation site of each equipment on vehicle of above-mentioned gas monitoring system can be selected to install according to the practical structures of motor vehicles and machines; different frame for movement installation site differences, these different installation sites all drop within the scope that the utility model protects.
The utility model compared with prior art has the following advantages:
(1) the light price material benefit of equipment;
(2) quick for installation, easy maintenance only needs construction maintenance place can finish installation;
(3) system's stable and reliable operation;
(4) can not change the dynamic characteristics of automobile.
