[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 and Figure 2 , the embodiment of the utility model provides a 3D storage location management system, which includes:

[0024] The TOF sensor 10 installed above the storage location can project N*N detection laser points on the entire storage location plane and generate 3D storage location information, and at the same time send the 3D storage location information to the TTL to RS485 module through the UART protocol.

[0025] In this embodiment, the TOF sensor 10 is mainly composed of two parts: the first part is a diode that emits infrared light, and the second part is a special laser matrix. The TOF sensor 10 can measure the time of reflection from an object accurately to nanoseconds.

[0026] In addition, TOF sensors can not only accurately calculate the distance between a single object and the sensor based on the reflection time, but also use the difference in laser return time and wavelength to accurately digitally characterize the target in three dimensions (3D) and intuitively draw out the various features of the target, thereby obtaining 3D storage location information.

[0027] Specifically, in this embodiment, the TOF sensor 10 is installed directly above the storage location. The TOF sensor has an 8*8 laser matrix, which can project 64 detection laser points on the entire storage location plane, and then form 3D stereoscopic height data of the entire storage location.

[0028] The TTL to RS485 module 20 is used to convert the 3D storage location information into detection data of RS485 level standard and then send it to the data acquisition terminal 30 .

[0029] The TOF sensor 10 supports UART. For stable long-distance communication, the UART needs to be converted to RS485, and a TTL to RS485 module 20 is required for switching.

[0030] The data acquisition terminal 30 receives the detection data through the serial port to RS485 module 40 and sends it to the WMS system 50 .

[0031] In this embodiment, the data acquisition terminal 30 may be a computer. The data acquisition terminal 30 communicates according to the station number of the TOF sensor 10, and one computer can be connected to multiple TOF sensors 10. In addition, the data acquisition terminal 30 needs to receive the detection data through the serial port to RS485 module 40.

[0032] After receiving the detection data, the data acquisition terminal 30 performs calculations based on the 3D height data to detect the quantity of goods in the current storage location. At the same time, the data acquisition terminal 30 WIFI communicates with the WMS system 50 via HTTP and sends the data to the WMS system 50 using the HTTP protocol JASON format.

[0033] The entire working process of this embodiment is described in detail below:

[0034] The WMS system 50 sends a command to the data acquisition terminal 30; the data acquisition terminal 30 parses the received command and extracts key information such as the storage location number; the data acquisition terminal 30 starts the TOF sensor 10 at the corresponding position to detect the storage location according to the storage location number; the TOF sensor 10 feeds back the detection result to the data acquisition terminal 30; the data acquisition terminal 30 processes the information, superimposes the originally received WMS information, packages it into JASON format and feeds it back to the WMS system 50, so that the management personnel can obtain the placement of materials on site based on these data and provide on-site data for tallying decisions.

[0035] In summary, the 3D storage location management system of this embodiment has the following improvements:

[0036] 1. Multi-point detection of the storage surface is realized through TOF sensor;

[0037] 2. Realize direct interaction with the WMS system, and improve the speed of detection and feedback data;

[0038] 3. The design of the transfer interface module solves the problems of easy interference and unstable detection during the detection process.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
