One end of the branch ventilation pipe 6 is connected with the air inlet of the telescopic cylinder 4, and the other end of the branch ventilation pipe 6 is connected with one end of the main ventilation pipe. The electromagnetic valve is fixed on the other end of the vent main pipe. The electromagnetic valve is electrically connected with the processing module, and the processing module is used for controlling the opening and closing of the electromagnetic valve. The solenoid valve is in a closed state by default. The initial position of the resistance block 5 is positioned outside the mounting hole 3, and after the gas in the telescopic cylinder 4 is exhausted, the resistance block 5 can retract into the mounting hole 3.

The detection module still includes a plurality of weight sensor and a plurality of pressure sensor, and weight sensor installs on the quotation, and in this embodiment, weight sensor's quantity is five, is the cross, installs respectively in the intermediate position of quotation, front side, rear side, left side and right side. The pressure sensors are installed in the conveying channels 2, and in the embodiment, at least one pressure sensor is installed at each of two ends of each conveying channel 2.

And the weight sensor and the pressure sensor are in signal connection with the processing module.

The processing module is used for acquiring weight information acquired by the weight sensor, calculating the gravity center of the goods based on the weight information, and generating a recommended carrying direction based on the gravity center of the goods. The communication module is used for sending the recommended carrying direction to the gateway.

Still include fork truck in this embodiment, fork truck includes transport fork and control end, and the control end is used for obtaining recommended transport direction and showing from the gateway. In this embodiment, the control end is provided with a display screen, and information is displayed through the display screen.

The processing module is also used for acquiring pressure data from the pressure sensor and judging whether the pallet is carried by the forklift currently or not based on the pressure data. If the forklift is used for carrying, the processing module also judges whether the carrying fork is fully inserted into the carrying channel 2 or not based on the pressure data, and if the carrying fork is not fully inserted into the carrying channel 2, the processing module sends position error information to the gateway through the communication module; and the control terminal is used for acquiring and displaying the position error information from the gateway.

The control end is also used for acquiring reloading information from the gateway and displaying the reloading information

When the acceleration of the current tray in the vertical direction is larger than the controllable acceleration, the processing module is also used for controlling the electromagnetic valve to be opened, and the abandoned cargo information is sent to the gateway through the communication module. The control end is also used for acquiring the abandoned cargo information from the gateway and displaying the abandoned cargo information.

The existing tray is mostly made of plastic materials, and the surface is smooth. Moreover, the carrying fork is easy to wear during long-term carrying, the surface is smooth, the friction force between the carrying fork and the pallet is low, and the pallet is easy to slide during carrying goods, so that the safety is affected. In this implementation, when the transport fork stretched into transport passageway 2 and lifted up the tray, can extrude resistance piece 5, resistance piece 5 can be compressed to flush with transport passageway 2's surface, and the cylinder in the telescopic cylinder 4 can produce decurrent pressure to resistance piece 5 simultaneously, makes resistance piece 5 paste tight transport fork, and the rubber layer on resistance piece 5 surface fully contacts with the transport fork, can strengthen the frictional force between transport fork and the tray on the whole. Moreover, only when the transport fork is inserted into the transport passage 2 to lift the pallet, the force between the resistance block 5 and the transport fork becomes large, and when the transport fork is inserted into the transport passage 2, the pressure between the resistance block 5 and the transport fork is small, the friction force is also small, and the abrasion of the rubber layer on the resistance block 5 can be reduced.

Before the pallet is transported, the gravity center of the pallet is calculated based on the weight information, then the recommended transporting direction is generated based on the gravity center of the pallet, and after the pallet is known by a worker operating the forklift, the pallet and the pallet can be transported from the recommended transporting direction. For example, the center of gravity of goods is in the left side of tray, and the transport direction of recommendation this moment is the left side of tray, and in staff's operation fork truck stretched into transport passageway 2 with the transport fork from the left side of tray, the transport like this, can let the center of gravity of goods more be close to fork truck, avoided leading to the fork truck perk because the center of gravity of goods keeps away from fork truck and the goods appear inclining in resulting in handling poor stability even.

If the carrying fork is not fully inserted into the carrying channel 2, the stability is poor in the carrying process, even the gravity center of the goods is too far away from the forklift, the goods incline, and the forklift tilts and the like. In this embodiment, after the staff sees position error message, can in time adjust the position of transport fork.

When the goods of fork truck transport is overweight, when fork truck lifted the goods moreover, the goods can incline to the direction of keeping away from fork truck, lead to fork truck to keep away from the afterbody perk of goods, whole fork truck topples even, endangers staff's in the fork truck personal safety. In this embodiment, can judge that present tray takes place the slope based on angle data, when taking place the slope, if the acceleration of the vertical direction of tray is less than or equal to controllable acceleration, it is slower to show that the speed that the goods appears the slope on the tray, and the staff has the time to deal with in addition, and at this moment, through sending reload information, be convenient for let the staff know the condition, operation fork truck falls the goods in order to avoid appearing the danger of toppling. Compared with the observation by experience of workers, the problem can be found earlier by adopting the acceleration sensor and the gyroscope, and more processing time is reserved for the workers.

When the acceleration of the vertical direction of the tray is larger than the controllable acceleration, the goods are indicated to be quickly inclined and cannot be remedied, and the safety of operators should be guaranteed preferentially at the moment. Therefore, the electromagnetic valve is opened, gas in the telescopic cylinder 4 is released, the pressure of the telescopic cylinder 4 on the resistance block 5 is reduced, the friction force between the resistance block 5 and the carrying fork is reduced, the resistance of the carrying fork and the tray is reduced on the whole, the tray with the goods slides off the carrying fork more easily, and after the tray with the goods slides off the carrying fork, the forklift can be kept, the overturning of the forklift is avoided, and the safety of workers in the forklift is guaranteed.
