Description

TECHNICAL FIELD

[0001] The present application relates to the field of waste treatment equipment monitoring, more particularly, to a wireless sensor for grab state monitoring. BACKGROUND

[0002] In the waste treatment industry, the grab of the waste crane is the core operation equipment, and its stable operation is crucial to the efficiency and quality of waste treatment. The grab relies on hydraulic devices to work, and hydraulic oil transmits pressure in it, and its working state affects the performance of the grab. The suitable temperature of the hydraulic oil is -10℃~ +80℃, the system opening oil pressure is 120bar, and the closing oil pressure is 190bar. Exceeding the range will reduce the efficiency of the grab, aggravate the wear of the parts, and even cause failure, interrupting the waste treatment process.

[0003] At the same time, the tilt angle of the grab is related to the operation safety, and the tilt angle (horizontal) is required to be less than 30 degrees.
