The data acquisition server M300 is in communication with the environmental information acquisition vehicle M100 and the worker terminal M200, specifically, the data acquisition server M300 is in communication with the first wireless communication module M140 and the second wireless communication module M250, respectively, and the data acquisition server M300 acquires environmental data acquired by the environmental information acquisition vehicle M100 and the worker terminal M200, respectively. The data acquisition server M300 stores the positions of a plurality of preset nodes in the production workshop and the numbers of the preset nodes. The positions and numbers of the preset nodes are set in a production workshop in advance by workers, for example, serial number stickers or nameplates of the preset nodes are attached to corresponding positions in the workshop. The preset nodes may be substantially uniformly arranged in the plant.

When the staff arrives a preset node, the number of the attached node can be seen, the staff can manually input the number of the preset node through a keyboard M210 of the staff terminal M200, the staff terminal M200 receives the number of the preset node input by the staff through the keyboard M210, and the ID of the staff terminal M200 and the number of the preset node are sent to the data acquisition server M300 through the second wireless communication module M250.

When the data acquisition server M300 receives the number of the preset node sent by the worker terminal M200 from the worker terminal M200, the mapping relationship between the ID of the worker terminal M200 and the number of the preset node is established, that is, the preset node which has established the mapping relationship with the worker terminal M200 at present is determined, and since the worker terminal M200 has been responsible for acquiring the environmental data, the environmental data acquisition vehicle may not pass through these places.

The data collection server M300 sets the position of a preset node that does not establish a mapping relationship with the worker terminal M200 as a patrol position, plans the operation route of the environmental information collection vehicle M100 according to each patrol position, and sends the operation route to the environmental information collection vehicle M100. When the data acquisition server M300 plans the operation route, it is ensured that the operation route can all pass through the patrol position, and for the preset nodes where the worker terminal M200 is responsible for acquiring the environmental data, the operation route may or may not pass through these nodes. Therefore, in the walking of the one-time running route of the environmental information collection vehicle M100, the environmental data of the patrol position can be collected.

After the environmental information collection vehicle M100 receives the operation route through the first wireless communication module M140, the collection vehicle controller M150 controls the movement assembly M110, so that the environmental information collection vehicle M100 moves along the operation route;

the staff member terminal M200 periodically sends the detection data of the second environment monitoring sensor M230 to the data collection server M300 through the second wireless communication module M250, and the data collection server M300 records the mapping relationship between the received detection data and the number of the preset node, thereby realizing the collection of the environment data at the preset node which has established the mapping relationship with the staff member terminal M200.

When the environmental information collection vehicle M100 arrives at each preset patrol position, the vehicle stays for a preset time, the detection data of the first environmental monitoring sensor M130 and the serial number of the preset node corresponding to the patrol position are sent to the data collection server M300 through the first wireless communication module M140, the data collection server M300 records the mapping relation between the received detection data and the serial number of the preset node, and therefore the environmental data collection of each patrol position is achieved.

The Internet of Things (The Internet of Things, IOT for short) is to collect any object or process needing monitoring, connection and interaction in real time and collect various required information such as sound, light, heat, electricity, mechanics, chemistry, biology and location through various devices and technologies such as various information sensors, radio frequency identification technologies, global positioning systems, infrared sensors and laser scanners, and to realize ubiquitous connection of objects and people through various possible network accesses, so as to realize intelligent sensing, identification and management of objects and processes. Therefore, based on the technology of the internet of things, the environment data at each position in the production workshop can be movably collected through the communication among the environment information collection vehicle M100, the worker terminal M200 and the data collection server M300 and the cooperative cooperation of the environment information collection vehicle M100 and the worker terminal M200, so that the sensor arrangement cost is saved, and the comprehensive data collection is realized. When planning the movement route of the environmental information collection vehicle M100, only the patrol position needs to be covered, and the frequency of data collection is also increased.

In this embodiment, when the environment information collection vehicle M100 finishes traveling on the current running route, the first wireless communication module M140 sends a route acquisition request to the data collection server M300. Considering that the position of each worker terminal M200 may change after a period of time and needs to be updated, the data collection server M300 re-counts preset nodes that do not currently establish a mapping relationship with the worker terminal M200 after receiving the route acquisition request, sets the position of the preset node that does not currently establish a mapping relationship with the worker terminal M200 as a patrol position, plans the operation route of the environment information collection vehicle M100 according to each patrol position, and sends the operation route to the environment information collection vehicle M100. Therefore, when planning the operation route, the data collection server M300 plans according to the real-time position of the worker terminal M200, thereby improving the accuracy of route planning.

In this embodiment, the production shop data acquisition system of the invention may also enable the dwell time setting, taking into account that the monitoring requirements may be different at different locations within the production shop. The data collection server M300 is further configured to receive the stop time of each preset node set by the staff, and send the stop time of each preset node corresponding to the patrol position and the running route to the environmental information collection vehicle M100. When the environmental information collection vehicle M100 travels along the travel route, the preset time of stopping at each patrol position is the stop time of the preset node received from the data collection server M300.

In this embodiment, the production shop data collection system may further implement automatic identification of the serial number, considering that it may take a long time for a worker to manually input the serial number of the preset node, and that it may also be input incorrectly to cause a mapping failure. Specifically, staff terminal M200 still is provided with the orientation module, the orientation module is GPRS orientation module, can acquire staff terminal M200's real-time position. The system further comprises cameras in one-to-one correspondence with the preset nodes and indicating lamps in one-to-one correspondence with the cameras, the cameras are arranged at the positions of the corresponding preset nodes, and the indicating lamps are arranged on one sides of the cameras.

when the data acquisition server M300 receives an automatic acquisition numbering request from the worker terminal M200, determining a preset node within a preset distance range around the worker terminal M200 as a candidate preset node according to the current position of the worker terminal M200;

the data acquisition server M300 sends a light-on signal to the indicator light corresponding to the alternative preset node, and sends a shooting signal to the camera corresponding to the alternative preset node; after seeing the indicator light which sends out the light-on signal, the worker can search for the camera closest to the worker, and the front face of the worker faces the camera to take a picture;

the data acquisition server M300 acquires the shot image of the camera and performs face recognition; the face recognition may adopt a face recognition mode in the prior art, for example, the image vector similarity may be calculated by comparing the shot image with a pre-stored image of a worker, where the comparison only requires comparing the face image of the worker corresponding to the worker terminal M200;

if the face of a worker corresponding to the worker terminal M200 is detected by a shot image of a camera, determining that a preset node corresponding to the camera is a preset node where the worker terminal M200 is located, and sending the serial number of the preset node to the worker terminal M200;

after receiving the number of the preset node, the worker terminal M200 displays the number on the display screen M220;

when receiving that the worker presses the confirmation key, the worker terminal M200 sends a confirmation signal to the data acquisition server M300, and after receiving the confirmation signal, the data acquisition server M300 determines the mapping relationship between the worker terminal M200 and the number of the preset node.

In this embodiment, when the data acquisition server M300 acquires the shot image of the camera and performs face recognition, if the face of the worker corresponding to the worker terminal M200 is not detected, an automatic detection failure signal is sent to the worker terminal M200, and the automatic detection number is no longer applicable, and at this time, the worker still needs to manually input the number. And when the staff terminal M200 receives the automatic detection failure signal, displaying an automatic detection failure notice on the display screen M220, and displaying a serial number for reminding staff to manually input a preset node.

Furthermore, in order to avoid the error of manual input of the serial number of the preset node by the staff, the invention also adds a mode of detecting and verifying according to the position. Specifically, when receiving a serial number of a preset node manually input by a worker, the worker terminal M200 determines whether the preset node is located within a preset range of a position of the worker, and if not, sends a serial number error signal to the worker terminal M200; and when the staff terminal M200 receives the number error signal, displaying a number error notice on the display screen M220 and prompting staff to input the number again.
