Abstract

The invention relates to a network system of a temperature sensor, comprising a temperature sensing cable and a temperature monitoring alarm controller connected with the temperature sensing cable, wherein a center layer of the temperature sensing cable comprises an earthing lead, a power supply lead, a data line and at least one chip temperature sensor; and the center layer is sequentially wound with a tetrafluoroethylene band, a metal net shielding layer and an extrusion molding fluoroplastic flame retardant outer sheath layer in sequence from inside to outside. The cable can be expanded in a linear shape, a tree shape, a star shape and mesh topology by an adapter. The network system has the characteristics of large protecting range, simple and reasonable structure, low cost, easy production and manufacture, convenient use, high temperature sensing sensitivity, multi-stage temperature alarm, accurate place location, no need of maintenance, repeated use, strong anti-electromagnetic interference capability, less influence of ambient temperature, expandability at any stage at will and the like. The network system has wide applicability, and is especially applicable to temperature monitoring and accident early warning in the severe environment such as dust, a subway, a tunnel, a cable channel and the like, the industrial places such as petroleum, petrochemical industry, a grain depot, a steel mill and the like, and the flammable and explosive dangerous places.

Description

technical field

[0001] The invention belongs to the field of sensors, in particular to a temperature sensor network system. Background technique

[0002] The linear temperature detector uses a temperature-sensing cable as a temperature detection element, which can complete temperature rise positioning and alarm in harsh environments such as pollution, dust, humidity and corrosion, so it is suitable for metallurgical enterprises, railways, tunnels, underground mines, It is widely used in chemical enterprises, large warehouses and substations. The linear detectors currently used are mainly divided into resistance-type cable-type temperature-sensing alarm cables and optical fiber-type temperature-sensing alarm cables. The resistance type temperature alarm cable part uses two elastic steel wires. Under normal circumstances, the two steel wires are insulated. Sound the alarm. This kind of detector has poor anti-interference ability and poor reliability. The alarm part needs to...
