Technical Field

The invention relates to the technical field of automatic weighing of travelling cranes, in particular to a travelling crane weighing system and a method.

Background

The travelling crane is the most important equipment for hoisting the materials in the current use, and can finish weighing the materials in the process of hoisting and loading and unloading the materials by the travelling crane. At present, when an enterprise uses a crane hook scale to hoist materials, the weighing display instrument is mainly used, and other personnel manually copy the materials to finish weighing; or the weighing display instrument is connected to the computer through a serial port to acquire the weight, a weighing operator instructs a vehicle operator to confirm weighing, and the weighing data is stored in the computer for management.

The above scheme has the defects that: the current applied modes are hoisted and weighed by a travelling crane, and the weighing personnel are required to carry out manual operation, so that the weighing posts are increased, and the situations of weighing cheating easily occur due to multiple human factors, so that the improvement is needed.

In addition, the stability of the weight is affected by the shaking of materials in the hoisting process, and factors such as manual determination and the like are needed after the weight is stabilized, so that the problems of long waiting time, low efficiency, multiple human factors and the like exist.
