Problems solved by technology

At present, the measurement and research on the thermal efficiency of arc light is mainly based on observing the color of arc light and measuring its luminous intensity. The luminous intensity can only reflect the instantaneous average value, and the overall luminous intensity distribution of the transient arc cannot be obtained
It is also difficult to effectively detect and control the operation and luminous efficiency of the arc lamp

specific Embodiment

[0122] HID high-efficiency energy-saving lamps and high-frequency ballasts developed by the Green Power Laboratory of North China University of Technology are selected. The purpose is to measure and understand the relationship between the luminous intensity distribution of the HID lamp and the driving current and voltage, and measure parameters such as arc start time. With conventional means, it is impossible to obtain intuitive and accurate measurement results.

[0123] Aim the detector at the HID lamp, and connect the current and voltage of the high-frequency ballast to the two input terminals of the control device through the converter. The image input method is real-time measurement.

[0124] Such as figure 2 As shown, it is the arc light image acquired at the time of power-on 1s, and the driving current and voltage displayed at this time are 1A and 1KV respectively.

[0125] Such as image 3 As shown, it is the arc image acquired at the time of power-on 5s, and the d...

Abstract

The invention discloses a monitoring system and the method for applying the monitoring system to monitor the operation of electric elements; the monitoring system comprises a detector, a controller and a monitoring center; the monitoring center receives temperature parameters information transmitted by the detector and the electric parameter information transmitted by the controller for processing; and then the monitoring center sends the control signal to the controller according to the processed results. The monitoring system also comprises an imaging device which is used for receiving the temperature parameter and electric parameter information transmitted by the monitoring center or the detector and displaying the information in the pattern of two-dimensional image. The detector comprises an infrared detector which can image through electronic scanning; the infrared is used for detecting the infrared radiation signal in the operation of the electric elements; the signal is processed by the monitoring center and then input into an imaging device; in this way, the monitoring system can directly detect the relationship between the luminous intensity of the arc lamp and the driving current and voltage and accurately detect the parameters such as the arc starting time; moreover, the monitoring system can control the high-efficiency operation of the arc lamp and is applicable to the operation of other electric elements.

Description

technical field [0001] The invention relates to a monitoring system and a method for monitoring the operation of electrical components, in particular to a method for monitoring the operation of arc lamps using arc imaging technology. Background technique [0002] With the development of society and technological progress, people have increasingly strong requirements for energy saving in industrial production and social life. Lamps are energy-consuming products commonly used in our daily life and production. Whether they are energy-saving is very important for us to achieve our energy-saving goals. [0003] Arc lamps, HID (high pressure intensity discharge) lamps, MH (metal halide) lamps, etc., have become the most popular light sources due to their advantages such as good color temperature, high luminous efficiency, stable brightness and long life. has received more and more attention. [0004] Whether it can save energy depends on the luminous efficiency of the arc it pro...
