[0052] When the transport vehicle 1-8 drives out of the sensing area of ​​the ground sensor III 5-3, the ground sensor information box II 5-6 transmits the information to the management terminal unit 6. The management terminal unit 6 prompts the driver to park the transport vehicle 1-8 in the parking area and open the car door through the access control. When the transport vehicle 1-8 enters the sensing area of ​​the ground sensor IV 5-4, the ground sensor information box II 5-6 transmits the information to the management terminal unit 6.

[0053] 3. Implementation process of sampling and photographing unit 3.

[0054] like Figure 7 As shown, the management terminal unit 6 operates the Vientiane robotic arm 3-2 through the information line VII 3-4 to extend to the appropriate position in the compartment of the transport vehicle 1-8, turns on the sampling camera 3-1 to take pictures, and stores them in the server database for future reference; the management terminal unit 6 prompts the driver through the access control 5-8 that the cleaning and disinfection inspection is completed, and drives the transport vehicle 1-8 away.
