example 1

[0020] The stacker and reclaimer walk towards the retaining wall during stacking and reclaiming, and a position sensor is installed near the retaining wall to prevent the reclaimer from colliding with the retaining wall. In the case of failure of the position sensor of the material retaining wall or the loose displacement of the impact block cannot be triggered, the reclaimer will continue to walk and collide with the material retaining wall due to the inability to receive the position signal, resulting in an equipment accident.

[0021] Under the same circumstances, the stacker and reclaimer equipped with the inventive device will judge that it has entered the position interval of the retaining wall based on the real-time measured travel wheel rotation data. If the position signal is not received, it will give a fault alarm to the position signal sensor system , and at the same time, according to the working status, the actions to avoid the risk of collision such as raising th...

Abstract

The invention relates to a device and a method for determining a real-time position of a stacker and reclaimer to avoid collision accidents. According to the device, a hardware composition comprises a power supply, a controller, an input and output module and signal acquisition sensors; software can automatically judge whether the related signal acquisition sensors are normal or not and measure the real-time position of equipment, stops a vehicle and gives an alarm when finding that dynamic monitoring sensor signals are abnormal, gives a corresponding alarm under the condition of finding that a position signal sensor system has a fault, and corrects measurement errors when position signals are normal; and control software measures the position of the equipment in real time, intelligently controls the equipment according to a logic and automatically locks the equipment or takes an evasive action when finding a collision risk. Therefore, offside accidents or collision accidents under the condition that any position signal or any anti-collision sensor is abnormal can be absolutely perfectly avoided.

Description

technical field [0001] The invention belongs to a device and method for preventing collisions and offside accidents of stacking and reclaiming equipment traveling on rails, and in particular can ensure that the equipment will not go offside or collide when various hardware devices are abnormal. Background technique [0002] At present, the stacking and reclaiming equipment of track walking generally use position and terminal signal sensors to determine the terminal and stage position of the equipment, and confirm the interval and terminal where the equipment is located according to the action state of the corresponding position signal sensor, so as to prevent offside collision or Collision with other devices in the same area. There is also an anti-collision signal device installed at the position where a collision may occur, and an emergency stop to prevent collisions when the anti-collision signal is activated. [0003] In the traditional method, whether an offside or coll...
