Abstract
The invention discloses an infrared real-time monitoring device of a switch cabinet. A plurality of temperature detectors are arranged; the temperature detectors are used for fully monitoring the interior of the switch cabinet in real time at a set rotation angle under the drive of a step motor; temperature sensors and optical mechanisms which are arranged on the temperature detectors are used for scanning and detecting surface temperature of an object to be detected, collecting infrared information in the cabinet and converting the infrared information into electric signals; real-time temperature in the switch cabinet to be detected is displayed by a temperature display; a Hall sensor is used for positioning electrification and revising step loss of the step motor so as to ensure the reliable running of the step motor; a temperature measuring master control end is connected with a single chip microcomputer through radio frequency receiving and transmitting circuits so that temperature and position failure points of the switch cabinet are remotely monitored; and by the arrangement of a temperature alarm device, when the temperature in the cabinet exceeds a normal range, the temperature alarm device sends out sound and light to alarm.
Description
Technical field
The present invention relates to Regulation real time monitoring field, relate in particular to the infrared real-time monitoring device of a kind of switch cubicle.
Background technology
In operation of power networks, the factors such as the long-time large load operation of high-voltage switch gear, joint is loosening, contact is aging cause contact resistance to increase, and then cause that contact temperature raises, when device temperature exceedes certain limit, not only can reduce equipment intensity, affect operation life, even also can cause that equipment damages, and causes a serious accident.At present, at home and abroad, to switch cubicle thermometric, the ripe method that can take roughly has three kinds: install sensor additional, be subject to aisle limit, differ and monitor surely actual heat generating spot, may occur undetected; Install perspective piece additional, can not realize Real-Time Monitoring; Adopt real time on-line monitoring, can not realize temperature measurement on-line in whole cabinet.
Summary of the invention
The object of this invention is to provide a kind of temperature real time on-line monitoring that both can realize full cabinet, again can be to localization of fault, and there is the infrared real-time monitoring device of switch cubicle of sound and light alarm and remote monitoring function.
For realizing the technical scheme that object of the present invention adopts be: the infrared real-time monitoring device of a kind of switch cubicle, comprise hygrosensor, stepper motor, Hall element, temperature indicator, temperature alarming device, thermometric main control end and control knob, described hygrosensor is connected with described stepper motor by driving stem, described hygrosensor, stepper motor, Hall element, temperature indicator, temperature alarming device, thermometric main control end is connected with single-chip microcomputer by circuit respectively with control knob, described Hall element is to the described stepper motor location that powers on, lose step correction, described thermometric main control end is connected with Long-distance Control end data.
Described hygrosensor comprises temperature sensor and optical facilities, and described hygrosensor is multiple.
Described temperature alarming device is audible-visual annunciator.
Described thermometric main control end is connected with single-chip microcomputer by radio frequency reception radiating circuit.
The present invention is by arranging multiple hygrosensors, described hygrosensor carries out comprehensive Real-Time Monitoring at the rotational angle of setting in to switch cubicle under the driving of stepper motor, and by being provided with temperature sensor and the optical facilities scanning probe object surface temperature on hygrosensor, gather the infrared information in cabinet, and be converted into electric signal, show the real time temperature in the switch cubicle detecting by temperature indicator; By Hall element to stepper motor power on location, lose step correction, guarantee the reliability service of stepper motor; Thermometric main control end is connected with single-chip microcomputer by radio frequency reception radiating circuit, realizes remote monitoring and the localization of fault of switch cabinet temperature; By set temperature warning device, in the time that in-cabinet temperature exceeds normal range, temperature alarming device can send sound and light alarm.Described thermometric main control end is connected with Long-distance Control end data, has effectively realized the remote monitoring function of the infrared real-time monitoring device of switch cubicle.
The present invention has realized temperature real time on-line monitoring, localization of fault, sound and light alarm and the remote monitoring function to full cabinet effectively, has very high popularization and using value.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1: the infrared real-time monitoring device of a kind of switch cubicle, comprise hygrosensor 4, stepper motor 3, Hall element, temperature indicator 6, temperature alarming device 1, thermometric main control end 7 and control knob, described hygrosensor 4 is connected with described stepper motor 3 by driving stem 5, described hygrosensor 4, stepper motor 3, Hall element, temperature indicator 6, temperature alarming device 1, thermometric main control end 7 and control knob are connected with single-chip microcomputer 2 by circuit respectively, and described thermometric main control end 7 is connected with remote control terminal 8 data.Described hygrosensor 4 comprises temperature sensor and optical facilities, and described hygrosensor is 3.Described temperature alarming device 1 is audible-visual annunciator.Described thermometric main control end 7 is connected with single-chip microcomputer 2 by radio frequency reception radiating circuit.
The present invention is by arranging multiple hygrosensors, described hygrosensor carries out comprehensive Real-Time Monitoring at the rotational angle of setting in to switch cubicle under the driving of stepper motor, and by being provided with temperature sensor and the optical facilities scanning probe object surface temperature on hygrosensor, gather the infrared information in cabinet, and be converted into electric signal, show the real time temperature in the switch cubicle detecting by temperature indicator; By Hall element to stepper motor power on location, lose step correction, guarantee the reliability service of stepper motor; Thermometric main control end is connected with single-chip microcomputer by radio frequency reception radiating circuit, realizes remote monitoring and the localization of fault of switch cabinet temperature; By set temperature warning device, in the time that in-cabinet temperature exceeds normal range, temperature alarming device can send sound and light alarm.Described thermometric main control end is connected with Long-distance Control end data, has effectively realized the remote monitoring function of the infrared real-time monitoring device of switch cubicle.
Owing to being detected object own radiation ability difference, surface oxidation degree, flatness all can affect its surface emissivity ability, in order to change its slin emissivity, make body surface there is high emissivity, and emissivity is unified, a little less than its surface applies one deck and can improve body surface radianting capacity, the coating material of the characteristic such as inconsistent, Effect on Detecting is better.
The present invention has realized temperature real time on-line monitoring, localization of fault, sound and light alarm and the remote monitoring function to full cabinet effectively, has very high popularization and using value.
