Problems solved by technology

Conventional safety monitoring is usually carried out for fixed counterweights. Equipment counterweights usually do not change during the hoisting operation, and the system safety margin basically does not change significantly and remains at a high level. Hoisting operations will easily be limited to Execute within a safe range, but for mobile counterweights, as the hoisting operation proceeds, the system adjusts the position of the counterweight according to the moment balance, the movement of the counterweight will affect the system safety margin, the sensor will fail or the sensor data will be inaccurate When the system moves the counterweight according to the sensor data of the faulty component or inaccurate sensor data, such as counterweight pushing out (or extrapolation, which can be relative to the center of gyration) should be performed in theory to maintain balance, but the counterweight is actually carried out. Heavy adduction, which will not only fail to provide sufficient safety margin for hoisting operations, but also aggravate the unbalanced force, and even lead to overturning accidents
What is even more worrying is that before the system loses the safety margin or the emergency safety control capability, the sensor data that does not reach the threshold or the faulty sensor that does not alarm and reaches the threshold is difficult to be identified by the system. It can be seen that using conventional fixed The monitoring method of the counterweight is difficult to realize the basic safety guarantee of the crane with the mobile counterweight

Abstract

The invention provides a fault double-layer redundant monitoring method, an early warning method and a system, which belong to the technical field of engineering machinery control. The method includes: obtaining sensor data of each operation parameter based on the sensor groups corresponding to the operation parameters on the hoisting device; in the first-level monitoring, based on whether the relevant actual detection value in the sensor data satisfies the configuration conversion relationship to determine whether the hoisting equipment is in the first fault condition, wherein the conversion relationship includes the geometric conversion relationship between the operating parameters corresponding to the relevant actual detected values; in the second-level monitoring, based on the Whether the actual detected value corresponding to the torque in the sensor data satisfies the torque balance relationship with the operating parameters of the corresponding torque, it is determined whether the hoisting device is in the second fault condition, wherein the hoisting device is not in the second fault condition. the first fault condition. The present invention can be used for equipment failure monitoring.

Description

technical field [0001] The invention relates to the technical field of engineering machinery control, in particular to a fault double-layer redundancy monitoring method, a fault double-layer redundancy early warning method, a fault double-layer redundancy early warning system, an electronic device, an engineering Machine and a computer readable storage medium. Background technique [0002] At present, crawler cranes and other cranes with excellent lifting capacity, etc., in the hoisting process, in order to improve the efficiency of counterweight use, improve hoisting capacity, and reduce the cost of transportation and installation of counterweight, they have begun to consider improving the traditional fixed counterweight to a variable counterweight. Front and rear moving counterweights for the stroke. Compared with the fixed counterweight, the mobile counterweight can expand the lifting capacity of the crane under the same counterweight size. In the hoisting operation, it...
