The invention discloses a dumper control method and device, a controller, a medium and a dumper, and relates to the technical field of control. The method comprises the steps that under the parking condition of the dumper, a lifting instruction is responded, the front portion of a carriage starts to be lifted, and the angle of a target connecting rod mechanism is obtained in real time through an angle sensor in the lifting process; determining a target front axle load corresponding to the target connecting rod mechanism angle according to a mapping relation between the front axle load and the connecting rod mechanism angle; when the target front axle load is within the first axle load range, the rotating speed of the power takeoff is controlled to be the rotating speed corresponding to the opening degree of the accelerator pedal; when the target front axle load is changed from the first axle load range to the second axle load range, the rotating speed of the power takeoff is controlled to be the minimum rotating speed of the power takeoff, wherein the opening degree of an accelerator pedal can be controlled; and when the target front axle load is changed from the second axle load range to the third axle load range, the rotating speed of the power takeoff is controlled to be reduced to 0. By the adoption of the control method of the dumper, the backward overturning risk of the dumper during carriage lifting and unloading can be reduced.

The application discloses a kind of based on two-dimensional cross arbitration's lift control method and system, the method includes the following steps: the logical association of the biological characteristics of passenger obtained with destination floor is established;Priority sequence of biological characteristics is established and biological characteristic mode score is distributed, the highest priority biological characteristics is not bound to fixed destination floor;Passenger grade priority sequence is established and passenger grade score is distributed;The product of biological characteristic mode score and passenger grade score is calculated to obtain comprehensive priority index, and comprehensive priority index is assigned to each lift instruction, and lift instruction with higher numerical value or earlier time stamp of comprehensive priority index is preferentially executed;The control instruction corresponding to the highest priority biological characteristics of the same passenger covers the destination floor associated with other biological characteristics of itself, the destination floor is updated, and the floor corresponding to the control instruction of the highest priority biological characteristics is responded to.The application can realize the priority response of biological characteristics with higher flexibility by combining two-dimensional cross arbitration strategy.

The application provides a safety control system of an experimental pool with a lifting function, which comprises a lifting platform installed at the bottom of the experimental pool and a wave generator arranged around the experimental pool. The lifting platform is in real-time communication connection with a lifting platform controller, the wave generator is in stable communication connection with a wave generator controller, and bidirectional data interaction and instruction transmission are realized between the two controllers to form a complete cooperative control system. In actual operation, after receiving a lifting instruction, the lifting platform controller inquires a first running state of the wave generator from the wave generator controller, and controls the lifting platform to lift according to the first running state. Similarly, before executing a wave making instruction, the wave generator controller actively acquires a second running state of the lifting platform, and controls the wave generator to make waves on the experimental pool according to the second running state, so that the reliability and safety of the whole system are ensured.

The invention discloses an elevator taking control method and system based on two-dimensional cross arbitration. The method comprises the following steps that logic association is established between obtained biological characteristics of passengers and a target floor; establishing a priority sequence of the biological characteristics and distributing modal scores of the biological characteristics, wherein the biological characteristic with the highest priority is not bound with a fixed target layer; establishing a passenger grade priority sequence and distributing passenger grade scores; calculating the product of the biological characteristic modal score and the passenger grade score to obtain a comprehensive priority index, distributing the comprehensive priority index for each elevator taking instruction, and preferentially executing the elevator taking instruction with a higher comprehensive priority index value or an earlier timestamp; the control instruction corresponding to the biological characteristic of the highest priority of the same passenger covers a target floor associated with other biological characteristics of the passenger, the target floor is updated, and the floor corresponding to the control instruction of the biological characteristic of the highest priority is responded. According to the method, the priority response of the biological characteristics with higher flexibility can be realized in combination with a two-dimensional cross arbitration strategy.
