Problems solved by technology
[0002] At present, the state detection method of most container spreader twistlocks is to detect the left and right sides separately, and the sensors of the front and rear twistlocks on each side are connected in series, so that when the front sensor (travel switch) fails or When it fails due to other electrical and mechanical reasons, misjudgment will occur, which will lead to machine damage accidents

Embodiment Construction
[0039] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.
[0040] see figure 1 , the present embodiment provides a method for controlling the twistlock of a single container spreader, the specific steps of which include:
[0041] S1. When the twistlock control system is turned on, it detects the internal state switch of the monitoring module, regards the twistlock detection module outputting the ON signal as the first monitoring module, and regards the state sensor corresponding to the first monitoring module as the first state sensor;
[0042] For the convenience of description, according to the preset logical relationship, the control system of the twistlock sets the monitoring modules that have a logical relationship with the first monitoring module as the second monitoring module and the third monitoring module r...

The invention provides a method for controlling the twistlock of a container single-box spreader, which includes the following steps: when the twistlock control system is turned on, it detects the internal state switch of the monitoring module, regards the monitoring module whose switch is in the ON position as the first monitoring module, and regards the first monitoring module as the first monitoring module. The corresponding state sensor is regarded as the first state sensor; the second monitoring module judges the theoretical working condition of the second state sensor through the second judgment method, and at the same time, the second monitoring module judges the Whether there is abnormality in the second state sensor; the third monitoring module judges the theoretical working condition of the third state sensor by the fourth judgment method; meanwhile, the third monitoring module judges whether the third state sensor exists by the fifth judgment method Abnormal situation: the first monitoring module judges the theoretical working condition of the first state sensor through the sixth judging method, and repeats the above steps at the same time, finally realizing the loop control of the twistlock.
Description
technical field [0001] The invention relates to the technical field of detection of the twist lock state of a spreader, in particular to a control method for a twist lock of a single container spreader. Background technique [0002] At present, the state detection method of most container spreader twistlocks is to detect the left and right sides separately, and the sensors of the front and rear twistlocks on each side are connected in series, so that when the front sensor (travel switch) fails or When it fails due to other electrical and mechanical reasons, misjudgment will occur, which will lead to machine damage accidents. Contents of the invention [0003] The object of the present invention is to provide a method for controlling the twistlock of a container single-case spreader to solve the problems raised in the above-mentioned background technology. [0004] The present invention is achieved through the following technical solutions: a method for controlling the twi...
