Beidou-technology-based cable shaft fire safety monitoring system of high-rise direct supply cell

Abstract

The invention discloses a Beidou-technology-based cable shaft fire safety monitoring system of a high-rise direct supply cell. The system comprises a central processing module, a communication management machine, an automatic fire extinguishing device and a circuit protection switch. The central processing module is in bidirectional connection with the communication management machine, the automatic fire extinguishing device and the circuit protection switch. The central processing module and a data acquisition unit are in bidirectional connection. The data acquisition unit includes N data monitoring instruments. The invention relates to the technical field of safety monitoring. According to the Beidou-technology-based cable shaft fire safety monitoring system, accurate and detailed firstinformation including detailed unit floor information is obtained when a fire occurs, so that the time and process of discovering the dangerous condition can be reduced and thus defects of small sealed environment space, poor cooling and ventilating performances, weak communication signal, and difficult moisture and humidity removing are overcome. The system has advantages of high smart fire protection requirement, small layout space, compact device density, and high technical requirement.

Description

technical field [0001] The invention relates to the technical field of safety monitoring, in particular to a fire safety monitoring system for cable shafts in high-rise direct supply communities based on Beidou technology. Background technique [0002] In recent years, there have been frequent fire incidents in high-rise buildings in domestic and foreign communities, and once a fire alarm occurs, the death rate is higher than other fire accidents. The cable shaft directly supplied to the community in the high-rise is used as a public cable, and there are few human-made repairs in the case of no failure. Its maintenance and prevention, and the power supply lines, power supply equipment and metering devices are mostly caused by improper use by customers or use beyond the rated metering capacity, as well as cable aging and insulation characteristics reduction caused by environmental influences, which are the main factors leading to frequent fire accidents one. [0003] There a...

Problems solved by technology

[0012] Aiming at the deficiencies of the prior art, the present invention provides a fire safety monitoring system for high-rise direct supply community cable shafts based on Beidou technology, which solves the problem that the external wireless communication signal of the existing high-rise direct supply shaft is weak, and when it is damp, the moisture is difficult to discharge and the space Small size, many internal cables, when a fire breaks out, the location of the fire cannot be determined in time
