Transmission line of electricity temperature Real-Time Monitoring and Forewarning TerminalTechnical field
The present invention relates to a kind of monitoring and Forewarning Terminal, particularly relate to a kind of transmission line of electricity temperature Real-Time Monitoring and Forewarning Terminal.
Background technology
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.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, in long-term high pressure, generate heat and the aging fire that causes, through investigation, most of fire failures are all because excess Temperature causes, the loss that especially fire of cable tunnel causes is maximum.For this reason, need a set of reliable, high performance automated system to carry out effective Real-Time Monitoring and warning to transmission line of electricity, to take preventive measures in time, avoid fire and power outage to occur.
Summary of the invention
The object of the invention is to provide in order to address the above problem a kind of easy for installation, cost is low, be applicable to transmission line of electricity temperature Real-Time Monitoring and the Forewarning Terminal applied under the environment of monitoring point complex distribution.
The present invention is achieved by 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, GPRS module, audible-visual annunciator, described in each, the signal output part of 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, the alarm signal output ends of described single-chip microcomputer is connected with described audible-visual annunciator.
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 of collection is transferred to signal acquisition module, then transfer to single-chip microcomputer, single-chip microcomputer carries out after analyzing and processing collecting temperature signal, respectively the signal after processing is transferred in data transmission module and storer, 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 are also provided with CPRS module, this monitoring is with alarm terminal and by GPRS module and monitor supervision platform, carry out wireless telecommunications and be connected.The feature of multifunction, microminiaturization, intellectuality, networking and the wireless penetration of employing wireless temperature measurement probe has overcome the drawback that cannot realize remote data transmission of conventional temperature sensor.
As of the present invention preferred, described transmission line of electricity temperature Real-Time Monitoring and Forewarning Terminal also comprise LED display.
Further, described in each, on wireless temperature measurement probe, be provided with RFID electronic tag.By on wireless temperature measurement probe, RFID label being set, position and the numbering of wireless temperature measurement probe can be input to RFID label, by rfid system, at software, accurately and timely grasp the place that occurrence temperature surpasses design temperature.
Further, the temperature-measuring range of described wireless temperature measurement probe is-55 ~ 150 ℃, and temperature measurement accuracy is ± 1 ℃.
The invention has the beneficial effects as follows:
Between wireless temperature measurement probe and data acquisition module, adopt wireless connections, need under complicated power grid environment, not increase extra circuit, both facilitated the I&M of system, reduced again the impact on electric power netting safe running, the security of system and dirigibility are greatly improved.The temperature long preservation that each monitoring point is recorded is also analyzed in real time, and the RFID label arranging on wireless probe can be easy to position surpassing the monitoring point of design temperature.
