The electromagnetic valve is fixed on the other end of the ventilation main pipe. The electromagnetic valve is electrically connected with the control chip, and the control chip is used for controlling the opening and closing of the electromagnetic valve. The solenoid valve defaults to a closed state. 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 sensor group 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 carrying passages 2, and in this embodiment, at least one pressure sensor is installed at each of the two ends of each carrying passage 2.
The weight sensor and the pressure sensor are both in signal connection with the control chip.
The control chip is also used for waking up the weight sensor and the pressure sensor after exiting the sleep mode, 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.
The embodiment also comprises a forklift, wherein the forklift comprises a carrying fork and a control end, and the control end is used for acquiring the recommended carrying direction from the gateway and displaying the recommended carrying direction. In this embodiment, the control terminal is provided with a display screen, and information is displayed through the display screen.
The control chip is also used for acquiring pressure data from the pressure sensor and judging whether the tray is currently carried by the forklift or not based on the pressure data. If the fork truck is used for carrying, the control chip also judges whether the carrying fork is fully inserted into the carrying channel 2 based on the pressure data, and if the fork truck is not fully inserted into the carrying channel 2, the control chip sends position error information to the gateway through the communication module; the control end is used for acquiring and displaying the position error information from the gateway.
The control chip is also used for acquiring acceleration data from the acceleration sensor during carrying, acquiring inclination angle data from the motion sensor, judging whether the current tray is inclined or not based on the inclination angle data, judging whether the inclination direction is a direction far away from the forklift if the current tray is inclined, and judging whether the acceleration of the vertical direction of the current tray is smaller than or equal to the controllable acceleration based on the acceleration data if the current tray is inclined or not; the control chip sends reloading information to the gateway through the communication module. The control end is also used for acquiring reloading information from the gateway and displaying the reloading information
When the acceleration of the vertical direction of the front tray is larger than the controllable acceleration, the control chip is further used for controlling the electromagnetic valve to be opened, and the discarded goods information is sent to the gateway through the communication module. The control end is also used for acquiring and displaying the discarded goods information from the gateway.
The existing tray is made of plastic materials, and the surface of the tray is smooth. And the carrying fork is easy to wear in long-term carrying, so that the surface is smooth, the friction between the carrying fork and the tray is low, and the tray is easy to slide during carrying goods, thereby affecting the safety. In this implementation, when the pallet is lifted to the transport fork stretch into transport passageway 2, can extrude resistance piece 5, resistance piece 5 can be compressed to flush with the surface of transport passageway 2, 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 pallet on the whole. Moreover, only when the carrying fork stretches into the carrying channel 2 to lift the tray, the stress between the resistance block 5 and the carrying fork can be increased, and when the carrying fork stretches into the carrying channel 2, the pressure between the resistance block 5 and the carrying 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 carrying, the weight information is used for calculating the gravity center of the goods, the recommended carrying direction is generated based on the gravity center of the goods, and after the operator operating the forklift knows, the pallet and the goods can be carried from the recommended carrying direction. For example, the center of gravity of goods is on the left side of tray, and the recommended transport direction is the left side of tray this moment, and staff operation fork truck stretches into in the transport passageway 2 with the transport fork from the left side of tray, carries like this, can let the center of gravity of goods be close to fork truck more, avoids leading to the poor stability of handling because of the center of gravity of goods is kept away from fork truck and even the goods appears inclining, leads to fork truck perk.
If the carrying fork is not fully inserted into the carrying channel 2, the carrying fork may have poor stability in the carrying process and even the gravity center of the goods is far away from the forklift too far to incline, so that the forklift is tilted and the like. In this embodiment, after the operator sees the position error information, the position of the carrying fork can be adjusted in time.
When the goods of fork truck transport are overweight, and fork truck lifts the goods in addition, the goods can be to keeping away from the direction slope of fork truck, leads to fork truck to keep away from the afterbody perk of goods, and whole fork truck overturns even, endangers staff's in the fork truck personal safety. In this embodiment, can judge that current tray takes place to incline based on inclination data, when taking place to incline, if the acceleration of tray vertical direction is less than or equal to controllable acceleration, indicate that the speed that the goods appears inclining on the tray is slower, and the staff has time to handle, at this moment, through sending reload information, is convenient for let the staff know the condition, operates fork truck and descends the goods in order to avoid the danger that the overturns. And compared with the acceleration sensor and the motion sensor which are observed by the staff through experience, the problem can be found earlier, and more processing time is reserved for the staff.
When the acceleration of the vertical direction of the tray is larger than the controllable acceleration, the cargo is indicated to be inclined rapidly and cannot be remedied, and the safety of operators is guaranteed preferentially at the moment. For this reason, the solenoid valve is opened, and the gas in the telescopic cylinder 4 is released, and telescopic cylinder 4 reduces the pressure of resistance piece 5 for the frictional force of resistance piece 5 and transport fork reduces, and the resistance of transport fork and tray reduces on the whole, and the tray is more easy from the transport fork landing with the goods, and after the tray is more from the transport fork landing with the goods, just can save fork truck, avoid fork truck to topple, guarantee the safety of staff in the fork truck.
