Embodiment 1
[0021] Such as figure 1 As shown, the flexible bag positioning device based on the acousto-optic combination detection technology includes: a base plate 1, a laser sensor 2, a reflective film 3, a flexible bag 4, and an ultrasonic distance measuring sensor 5; the flexible bag 4 is a rectangular elastic bag, flexible The center of the bottom surface of the bag 4 is fixedly attached to the bottom plate 1, and the edges of the four sides of the flexible bag 4 are respectively pasted with reflective film 3, and four laser sensors 2 are respectively fixed on the bottom plate 1 to cooperate with the reflective film 3. The laser light emitted obliquely by the laser sensor 2 is only blocked and reflected by the reflective film 3 when the flexible bag 4 is in a full state, and then the reflected laser light is received by the laser sensor 2. The ultrasonic distance measuring sensor 5 is fixedly installed on the flexible bag 4 The upper part of the center of the top surface is used to ...

Flexible bag positioning method based on acousto-optic combined detection technology, belongs to SF 6 In the field of gas detection technology, the technical solution of the present invention is to solve the problem that the expansion degree of the flexible bag cannot be effectively and accurately detected due to irregular deformation, wrinkles, etc., resulting in stopping the operation before the flexible bag is full. Using acousto-optic combined detection technology, ultrasonic distance measuring sensor is used to detect the height of the center of the top surface of the flexible bag, and a laser sensor is used to detect the height of the edge of the flexible bag. Full of states, the method is easy to implement.
Description
technical field [0001] The invention belongs to SF 6 The field of gas detection technology relates to a flexible bag positioning method based on acousto-optic combined detection technology. Background technique [0002] SF 6 In the operation and maintenance of gas-insulated substations, it is necessary to detect the moisture and impurity content of the insulating gas to judge whether the operation of electrical equipment is safe. But since SF 6 Greenhouse effect of gases and SF 6 There may be toxic decomposition products in the gas, which does not allow direct discharge of the tail gas for detection. [0003] Common SFs currently in use in the field 6 Gas detection instruments generally include decomposition product testers, purity meters, dew point meters, and comprehensive testers. Most of the recovery devices use compressors to pressurize and recover the tail gas, resulting in the use of recovery devices that may easily cause instability in the gas outlet pressure a...
