ZigBee-based safety defending system for inspection workshop staffs

Abstract

The invention relates to the field of wireless monitoring, in particular to a staff safety defending system based on a ZigBee wireless sense network. The system comprises n sensor nodes, a gateway node, an inspection workshop monitoring centre, pre-programmed monitoring software arranged on the inspection workshop monitoring centre, and an inspection workshop access control system, an inspection operation table and an acousto-optic alarm device which are connected with the inspection workshop monitoring centre, wherein n is a positive integer; the sensor nodes are connected with the gateway node through a ZigBee wireless communication protocol; the gateway node is accessed into the inspection workshop monitoring centre through an Ethernet network; and the inspection workshop monitoring centre is used for operating the monitoring software and correspondingly controlling the access control system, the inspection operation table and the acousto-optic alarm device according to the data treatment result of the monitoring software. According to the method provided by the invention, an inspection workshop wireless monitoring network is designed, so that the radiation protection capability of inspection workshop staffs is enhanced and the safety of staffs is improved.

Description

technical field [0001] The invention belongs to wireless communication technology and environment monitoring technology, in particular to a ZigBee-based personnel safety protection system in a flaw detection workshop. Background technique [0002] The flaw detection workshop of a welding factory is a place where radioactive sources are often used for workpiece flaw detection. Radiation protection is a very important part. Obtaining radiation change information in the flaw detection workshop is very important to ensure that workers are protected from radiation damage. [0003] In addition, due to the frequent use of radioactive sources in flaw detection workshops, the probability of potential nuclear leakage accidents is very high. In the event of a nuclear accident such as radiation source falling off or source jamming, the radioactive source will pollute the environment, and may cause workers and the public to receive excessive exposure, and even death in severe cases. The...

Problems solved by technology

[0006] Nuclear accidents are sudden and very harmful. It is necessary to establish data transmission with the monitoring and command center immediately when the incident occurs. There must be no serious errors in the transmission. Delay in time will cause unimaginable consequences.

Therefore, the transmission of on-site environmental information data must have good real-time performance and high accuracy. In ad
