The data acquisition module can collect the environmental information around the trolley, such as the environmental information on both sides of the trolley, the environmental information behind the trolley and the obstacle information in front of the trolley; the data acquisition module can also collect the real-time position of the trolley. The data transmission module can realize wireless transmission between information, such as Bluetooth, WLAN, 2.4G, 4G, 5G, mobile data and other wireless transmission modules. The data processing module can be used to coordinate each component module of the device, such as the MCU module. The function button matrix is used for manual operation to start various preset functions, and the function button matrix can include one or more function keys, and the function keys correspond to the preset functions. The preset functions can include planning the running path of the trolley, making the trolley stop suddenly or making the trolley return, etc. The motor driving module can drive the trolley to advance at a set speed. The steering engine steering module can drive the front wheels of the trolley to deflect by a required angle, so as to realize the turning of the trolley in cooperation with the motor driving module. The voice prompt module can perform voice prompting. The remote monitoring server can realize the remote monitoring of the trolley by the management personnel.

[0015] The working process of the system is: the data acquisition module collects the real-time position of the trolley and the surrounding environment information, the remote management personnel operates the remote monitoring server to send a certain operation instruction or the on-site management personnel presses a certain function button to start the corresponding preset function, the data processing module receives the surrounding environment information of the trolley sent by the data acquisition module, analyzes the position of the trolley, plans the running path according to the started preset function, and sends the operation instruction, which can include the moving direction instruction and the moving speed instruction. The motor driving module and the steering module receive the operation instruction, change the running state of the trolley, and go to the destination according to the planned path; the motor driving module can execute the moving speed instruction, and the steering module can execute the moving direction instruction. The data processing module receives the surrounding environment information of the trolley collected by the data acquisition module during operation, analyzes whether the trolley is running normally. If the trolley is not running normally, a stop moving instruction is sent, and fault information is reported to the remote monitoring server. If the trolley is running normally, it is judged whether the trolley has run to the destination. If not, continue to run according to the planned path until the destination; if the trolley has run to the destination, a stop running instruction is sent, a voice prompt is given by the voice prompt module, and a task completion information is reported to the remote monitoring server. The data acquisition module collects the surrounding environment data of the trolley in real time and uploads it to the remote monitoring server, and the management personnel can view it in real time. The remote monitoring server automatically archives each reporting record and reporting time.

[0016] For the data processing module, it can receive the remote operation instruction sent by the remote monitoring server, so as to start the corresponding preset function. The data processing module can receive the operation instruction sent by the function button, so as to start the corresponding preset function. The data processing module can also automatically execute the preset function according to the specified time, so as to control the automatic running of the trolley according to the environment information and position information collected by the data acquisition module. The function button can realize mechanical movement, and when one of the function buttons in the function button matrix is pressed, it can match the mode preset on the data processing module to start the corresponding different running mode (preset function). The function button can be automatically reset after being triggered, and the data processing module automatically records the function button number and executes the corresponding running mode. A certain function button can be defined as an emergency stop function, which can pause all operation instructions and stop the movement of the trolley. Of course, the function button can also be a touch button.

[0017] For the automatic driving of the trolley to realize the preset function, it is usually applied to fixed scenes, such as room meal delivery service in hotels and medicine delivery service for patients in hospital wards; in order to realize the automatic driving of fixed scenes, an identification can be pasted on the ground of the fixed scene for accurate positioning and identification by the data acquisition module, such as pasting an identification image at each ward and bed corridor corner. Of course, for different scenes, the types of identification can be different, and the types of carriers and corresponding data acquisition modules can also be different.
