Abstract
The invention discloses an on-line infrared temperature monitoring device, which is characterized in that infrared temperature probes arranged on each temperature monitoring point by groups are connected with respective temperature signal collectors in a bus mode; each temperature signal collector is in networking connection with a computer; the computer is communicated with a plurality of signal collectors in a polling communication mode; the collected temperature signal is subjected to real-time display and data storage and is conveyed to a GSM (global system for mobile communications) or GPRS (general packet radio service) modulator demodulator; and the GSM or GPRS modulator demodulator is conveyed to a remote mobile phone in a wireless communication mode to be displayed or alarmed. The on-line temperature monitoring device for high-voltage electric equipment is especially suitable for unattended transformer substations, not only the automated monitoring level can be improved, but also the fire hazard accident occurrence rate of the equipment can be greatly lowered.
Description
Technical field
The present invention relates to a kind of temperature on-line monitoring device of high voltage electric equipment.
Background technology
The electrical equipments such as high-tension switch cabinet are in long-term production run, the contact of its switch and the junction of bus, very easily produce loosening because of electrodynamic effect, and then the phenomenons such as loose contact and excess Temperature appear, thereby very easily cause the electrical fire accident, especially unattended transformer station, especially fault place occurred frequently.
For the contact that monitors switch and the temperature of bus junction, at present, the way that often adopts is by manually patrolling and examining test with infrared temperature-measuring gun.Although the method is simple and convenient, can not accomplish Real-Time Monitoring, especially can't monitor the temperature spot in handcart switch cabinet and the enclosed busbar.Carry out temperature detection with infrared thermoviewer and can carry out Real-Time Monitoring, but cost is very high, also inapplicable to switch cubicle and enclosed busbar simultaneously.Carry out thermometric with Fibre Optical Sensor, measuring accuracy is higher, and is applicable to various conditions, but system complexity and cost are too high.Though the radio temperature measurement on-line can be realized high-acruracy survey, but because its probe is installed in the metal box of sealing, radio signal can't transfer data to outside the metal box accurately and effectively, and the radio thermometric needs powered battery, because handcart switch cabinet and high voltage bus can't have a power failure at any time, thereby the people can't approach, so battery also can't be changed.
Summary of the invention
Purpose of the present invention just provides a kind of temperature on-line monitoring device, and this device is the intelligent temperature on-line monitoring device that integrates computer technology, infrared digital temperature sensor technology, Signal Collection Technology, wireless communication technology.
To achieve these goals, the present invention is achieved through the following technical solutions:
A kind of infrared temperature on-Line Monitor Device, it is characterized in that: the infrared temperature probe that is arranged on each temperature monitoring point by grouping is connected with separately temperature signal collection device in the mode of bus, each temperature signal collection device carries out networking with computing machine and is connected, computing machine adopts communication mode and a plurality of signal picker of poll to carry out communication, the temperature signal that collects shows and data storing in real time, and sending GSM or GPRS modulator-demodular unit to, GSM or GPRS modulator-demodular unit send long-range mobile phone in the mode of radio communication again and show or report to the police.
Described temperature signal collection device inside is provided with single-chip microcomputer, single-chip microcomputer and power module, storer, LED display module, output module, load module are electrically connected, and the input end of load module is connected with the infrared temperature probe of outside, and the output terminal of output module is connected with the computing machine of outside.
