Background technology

The transmission line of electricity safe operation is the problem that departments at different levels pay much attention to always.For many years, although taked many safety practices and technology, still have many hidden danger, security incident happens occasionally.In long-term high pressure, generate heat and the aging fire that causes at power equipments such as power plant and transformer station's cable testing bridge, cable tunnel, cable interlayer, cable duct, cable shaft, switchgear, transformer, resistor chains, through investigation, most of fire failures are all because excess Temperature causes that especially the loss of the fire of cable tunnel initiation is maximum.For this reason, need reliable, the high performance automated system of a cover to come transmission line of electricity is carried out effective Real-Time Monitoring and warning, in order in time take preventive measures, avoid fire and power outage to occur.

Summary of the invention

The purpose of this utility model be provide in order to address the above problem a kind of easy for installation, cost is low, be fit to transmission line of electricity temperature Real-Time Monitoring and the Forewarning Terminal used under the environment of monitoring point complex distribution.

The utility model is achieved through the following technical solutions:

A kind of transmission line of electricity temperature Real-Time Monitoring and Forewarning Terminal, comprise a plurality of wireless temperature measurement probes, single-chip microcomputer, data acquisition module, data transmission module, storer, the GPRS module, audible-visual annunciator, the signal output part of each described wireless temperature measurement probe is connected with the signal input part wireless telecommunications of described data acquisition module, the signal output part of described data acquisition module is connected with the signal input part of described single-chip microcomputer, described single-chip microcomputer is connected with described storer, described single-chip microcomputer is connected with described GPRS module by described data transmission module, and the alarm signal output ends of described single-chip microcomputer is connected with described audible-visual annunciator.

The wireless temperature measurement probe is installed on the node that needs monitor temperature, wireless temperature measurement probe collecting temperature signal, by wireless network the signal that gathers is transferred to signal acquisition module, then transfer to single-chip microcomputer, after single-chip microcomputer carries out analyzing and processing to the collecting temperature signal, signal after will processing respectively is transferred in data transmission module and the storer, and when the temperature of monitoring has surpassed the temperature of setting, single-chip microcomputer starts audible-visual annunciator and gives the alarm.

Because transmission line of electricity temperature Real-Time Monitoring and Forewarning Terminal also are provided with the CPRS module, this monitoring is with alarm terminal and carry out wireless telecommunications by GPRS module and monitor supervision platform and be connected.The characteristics of multifunction, microminiaturization, intellectuality, networking and the wireless penetration of employing wireless temperature measurement probe have overcome the drawback that can't realize remote data transmission of conventional temperature sensor.

As of the present utility model preferred, described transmission line of electricity temperature Real-Time Monitoring and Forewarning Terminal also comprise LED display.

Further, be provided with the RFID electronic tag on each described wireless temperature measurement probe.By at the wireless temperature measurement probe RFID label being set, position and the numbering of wireless temperature measurement probe can be input to the RFID label, accurately and timely grasp the place that occurrence temperature surpasses design temperature by rfid system at software.

Further, the temperature-measuring range of described wireless temperature measurement probe is-55 ~ 150 ℃, and temperature measurement accuracy is ± 1 ℃.

The beneficial effects of the utility model are:

Adopt wireless connections between wireless temperature measurement probe and the data acquisition module, need under the power grid environment of complexity, not increase extra circuit, both made things convenient for the I﹠M of system, reduced again the impact on electric power netting safe running, Security of the system and dirigibility are greatly improved.The temperature long preservation that each monitoring point records is also analyzed in real time, and the RFID label that arranges on the wireless probe can be easy to the monitoring point that surpasses design temperature is positioned.
