Abstract
The utility model discloses an infrared temperature monitoring system, which comprises a control main unit, at least one infrared temperature measuring device and an image server. The infrared temperature measuring device communicated with the control main unit is a double-path/four-path infrared temperature measuring instrument, and probes of the infrared temperature measuring instrument are in fan-shaped distribution and respectively acquire the temperature of an object with interval time set by the control main unit. The infrared temperature monitoring system solves the problem of higher false alarm rate of an existing main transformer temperature measuring device of a power transformer substation, improves correct alarm rate from original 20% to higher than 80%, and can monitor field running of a power device at any time by the aid of a management center by the aid of a powerful network monitoring function.
Description
Technical field
The utility model relates to temperature monitoring system, relates in particular to a kind of infrared temperature supervisory system that is used for power equipment.
Background technology
The contact-free measurement of temperature that is undertaken by the infrared ray that receives the testee radiation has a lot of advantages.Particularly be difficult to touch or body in motion just can carry out temperature survey without a doubt,, at this moment certain advantage arranged with infrared measurement of temperature as many equipment that are not easy to contact are arranged in the electric system for those.By remote remote metering, can make operating personnel not have danger away from the hazardous location, the far distance automatic monitoring of realization transformer etc.
At present, the main transformer thermometric of electricity substation realizes by cable type linear temperature-sensitive detector that generally this kind mode is very unstable, and false alarm is higher, and correct alarm rate has only about 20%.It is that testee is carried out focusing-detection that another kind utilizes the device of infrared measurement of temperature, as shown in Figure 1.This thermometric mode, the result of detection is out of true also.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of improved infrared temperature supervisory system, and this system can increase substantially the correct alarm rate of system.
The infrared temperature supervisory system of the utility model design comprises: a main control system; At least one infrared temperature measurement apparatus of communicating by letter with this main control system, this infrared temperature measurement apparatus is made up of signal picker and video encoder; An and image server.
In a preferred embodiment of the present utility model, be provided with the converter of regulation voltage between described main control system and the infrared temperature measurement apparatus.Described main control system can also be provided with accident warning device and overtemperature alarm device.Described infrared temperature measurement apparatus can adopt two-way or No. four infrared thermometers, and its probe is fan-shaped distribution, and sets the temperature of gathering testee interval time respectively by main control system.The distance of described infrared temperature measurement apparatus between testee is 5 to 10 meters, and the area between the testee collection point is 5 meters * 5 meters.
Compared with prior art, the infrared temperature supervisory system of the utility model design has following advantage:
(1) solves the main transformer temperature measuring equipment false alarm rate problem of higher of present electricity substation, correct alarm rate is provided to more than 80% by original about 20%.
(2) powerful network monitoring function can be monitored the on-the-spot ruuning situation of power equipment at any time by administrative center.

Fig. 2 is the synoptic diagram of the fan-shaped distribution of infrared temperature measurement apparatus;
Fig. 3 is the synoptic diagram of the utility model one embodiment.
Embodiment
As shown in Figure 3, the infrared temperature supervisory system that the utility model proposes comprises: a main control system 1, at least one infrared temperature measurement apparatus 2 of communicating by letter with this main control system and an image server 3.Infrared temperature measurement apparatus comprises signal picker and video encoder.
At 5-10 rice, the area suggestion of infrared point irradiation testee is 5 meters of 5 meters * to infrared temperature measurement apparatus 2, is up to 10 meters of 10 meters * from the distance of testee 4.
General infrared temperature measurement apparatus all is 24V to the alarming line of main control system at present, and the gunlock of infrared temperature measurement apparatus all is 9V, so a power supply changeover device 5 is set between main control system 1 and infrared temperature measurement apparatus, carries out the conversion of 24V-9V.
Because in the process of infrared acquisition, the effect of infrared device is just reaching infrared device and having certain thermal inertia, adopt many probes to help improving accuracy of detection and reliability.In the present embodiment, infrared temperature measurement apparatus 2 can use two-way or No. four infrared thermometers, and its probe is fan-shaped distribution, the temperature that each probe collection point is gathered testee respectively by the time interval (can artificially be provided with), as shown in Figure 2.For example, fan-shaped infrared radiation collection point is divided into abcd and each four point of efgh are gathered, and collection point abcd gathers once, separates 30 seconds, and collection point efgh gathers once.The temperature that collection point abcd and efgh collect is delivered to main control system in the node mode; The temperature that requires simultaneously to report to the police can be controlled, generally between 70 °-110 °; Promptly the temperature that ought collect is higher than assigned temperature, and in the time of such as 70 °, main control system is reported to the police, but does not report to the police when being lower than 70 °.
During work, the major function that the infrared temperature measurement system of band picture control is realized is as follows:
(1) can be automatically each device temperature of each transformer station be carried out infrared temperature and patrol and examine, when finding that temperature is high, report to the police automatically;
(2) when carrying out the designated equipment temperature patrol inspection, can show the realtime graphic of current device;
(3) can carry out infrared temperature to certain part of designated equipment detects;
(4) can carry out temperature compensation at various device and proofread and correct (the reflection coefficient difference that various device and surface red are outer);
(5) infrared temperature test in many places can be automaticallyed switch, and helps the long testing element life-span of the court of a feudal ruler and improves precision;
(6) can carry out the preset point setting, can carry out a plurality of equipment and zone detection, help reducing cost with same checkout equipment.
