[0041] The working principle of the intelligent automatic driving sample transport vehicle of the present invention is as follows:
[0042] When the key is in the ON position, the vehicle electrical system is connected to a 24V low voltage power supply, and the system self-checks. If there is no problem in the self-check, it can continue to rotate to the START position to connect to the high voltage, or wait for the background industrial computer to command to connect to the high voltage.

[0043] When an obstacle appears during operation, the product will take emergency braking or slowly decelerate to the set distance for braking, depending on the set distance, until the obstacle leaves the channel range and then continues to run along the prescribed route;

At the same time, it communicates with the charger data through the CAN bus to complete both fast charging and normal charging modes.
[0045] The sample transport vehicle is automatically and accurately connected with the secondary collection unit and the decentralized secondary automatic sorting and feeding unit; the sample transport vehicle is seamlessly connected with the secondary collection unit and the decentralized secondary automatic sorting and feeding unit, and the sample barrels are automatically transported; the high-precision positioning technology is used, and under the coordinated command of the sample barrel circulation system and the traffic control system, the route is automatically planned, and accurate positioning can be achieved, so that unmanned loading and unloading of sample barrels can be realized; it has the functions of automatic opening and closing of rolling doors and fixing of sample barrels in the vehicle.

The automatic sample barrel sorting device has the function of automatically docking with the AGV unmanned transport vehicle, automatically transporting the sample barrels to the system, and then waiting to receive commands from the control center.

[0049] When the sample transport vehicle arrives at the destination, it communicates with the equipment and confirms that the sample transport vehicle has arrived. The docking success signal is reported to the upper system (if the docking equipment does not involve the production information flow, such as a hoist or rolling door, the docking signal may not be reported to the upper system, but directly reported to the AGV scheduling system); after confirmation, the upper system issues an action command, and the sample transport vehicle and the equipment start to move;
[0050] Through the sample barrel circulation system, the vehicle status (standby, running, charging, maintenance, fault) of the sample transport vehicle, vehicle power tracking, vehicle location information (update frequency is not less than 1S / time) and operation route tracking, and remote real-time monitoring of the vehicle (through the on-board camera) can be achieved.
