Embodiment Construction
[0012] refer to figure 1 ,, the gas detection and alarm wireless terminals 1 carried by the staff scattered in the target area, according to the wireless terminal transmission signal coverage, the required number of gas detection and alarm wireless routers 2 and a wireless network coordinator 3 in the area are dispersedly set composition. The wireless terminal and wireless router are composed of gas sensor, sensor electrical signal conversion circuit, wireless single-chip microcomputer, liquid crystal display module, radio frequency antenna, alarm circuit and battery circuit. The wireless network coordinator includes a computing processing unit, a radio frequency module unit connected thereto, and a data storage unit. The gas sensors are 4H / LM CiTiceL (H2S hydrogen sulfide sensor), 4CF CiTiceL (CO carbon monoxide sensor), 4OX(2) CiTiceL (O2 oxygen sensor) and 4P-75C CiTpeL (LEL flammable sensor) from CITY TECHNOLOGY. gas sensor). The wireless microcontroller adopts the new ...

The invention discloses a target area harmful gas dispersion detection fixed point concentrated alarm wireless network, belonging to a detection technology. The target area harmful gas dispersion detection fixed point concentrated alarm wireless network comprises gas detection alarm wireless terminals dispersed in a target area and carried about by workers, gas detection alarm wireless routers dispersed in the target area according to a coverage range of emitting signals of the wireless terminals and a wireless network coordinator. The transmission relationship of the gas detection alarm wireless terminals, the gas detection alarm wireless routers and the wireless network coordinator is as follows: wireless transmission is adopted between the wireless terminals and the wireless routers, and wireless transmission is adopted among the wireless routers and between the wireless routers and the wireless network coordinator. The invention has the positive effects that the target area harmful gas dispersion detection fixed point concentrated alarm wireless network can be used for immediately and accurately carrying out real-time detection, monitoring and alarm on contents of toxic gases, oxygen and combustible gases of all nodes in a specific area, and immediately reflecting dangerous conditions in working places such as oil fields, coal mines, environment protection places and the like so that casualty accidents are avoided.
Description
technical field [0001] The invention belongs to detection technology and specifically designs a wireless network detection system for dispersed detection of harmful gases in a target area, fixed-point centralized alarm. Background technique [0002] Existing portable gas detection and alarm instruments are usually used to protect the safety of individual workers in specific target areas (such as oil fields, coal mines, etc.), and cannot form a network to transmit dangerous gas information to command centers and rescue units, and cannot monitor the entire work. All-round real-time detection and alarm in the region will not be able to mobilize public resources in a timely manner to respond to dangerous situations in a timely manner. Contents of the invention [0003] The purpose of the present invention is to provide a wireless network for distributed detection of harmful gases in target areas, fixed-point centralized alarm. [0004] What the present invention aims to solve...
