Detailed Description
Specific embodiments of the present invention are described below with reference to fig. 1-2.
The UWB positioning tag batch management method based on the UWB technology is characterized by comprising the following steps:
and S001, the UWB tag 1 encodes the data according to an agreed compression mode and then transmits the state data of the UWB tag 1 to the outside by using a UWB transmission technology.
In the above embodiment, further: the tag self state data sent to the outside by the step S001 includes message length information, validation information, tag MAC address information, tag battery power, tag firmware version information, tag configuration information, and message type information.
In the above embodiment, further: the message length information is used for explaining the length of the whole data message.
The check information is used for verifying the correctness of the message and is convenient and accurate to look up.
The tag MAC address information is used for identifying the unique tag of the UWB tag 1, so that the tracing is convenient, and the error and confusion are prevented.
The electric quantity of the tag battery is used for the manager to find out the UWB tag 1 with insufficient electric quantity in time and replace the battery, so that the tag can be continuously used.
The label firmware version information is used for checking the firmware version of the label operation, so that the problems that data formats are inconsistent, terminals cannot decode correctly and the like caused by inconsistent firmware versions are avoided.
The tag configuration information is used for detecting the sending frequency channel setting information of the currently running UWB tag 1, so that an administrator can find the tags with abnormal states conveniently.
The message type information is used for distinguishing different types of messages; the different types of messages include a positioning message, a keep-alive message, and a fault message, and are not limited to the above messages.
The UWB tag 1 encodes the above information in a predetermined compression manner, and transmits the encoded information using a UWB ultra-wideband transmission technology.
Step S002, the UWB base station 2 receives tag data information sent by all UWB tags 1 within a certain range of the base station, after the UWB base station 2 receives the tag data information sent by the UWB tags 1, the UWB base station 2 filters the types of the tag data information according to the types of the received UWB tags 1 in the data packet, and all management information is filtered; so as to meet the management requirement of the UWB tags 1 in large batch in practical application and prevent errors.
The management using the message has the advantages that the number and the state of the labels can be rapidly collected in batches, the problems that manual label counting in the early stage consumes time and is easy to generate errors are solved, and the working efficiency is improved. Compared with the method for checking the label configuration information in an earlier stage through connection in other modes, the method has the advantages that the data acquisition speed is high, the data of a large number of labels in a formulated range can be acquired in batches, and an administrator can manage the large number of labels conveniently.

It should be noted that: UDP is an abbreviation of User Datagram Protocol (UDP), a chinese name is a User Datagram Protocol, and is a connectionless transport layer Protocol in an Open System Interconnection (OSI) reference model, and provides a transaction-oriented simple unreliable information transfer service. Since UDP is a connectionless protocol, the source and the terminal do not establish a connection before transmitting data, and therefore, there is no need to maintain connection states, including a transceiving state, and the like. UDP has better real-time performance and higher working efficiency than TCP; the UDP segment structure is simpler than that of TCP, and therefore the network overhead is also small. The UDP is designed to allow multiple destination addresses to be identified on a given host, while allowing multiple applications to operate on the same host and independently transmit and receive packets.
WebSocket is a protocol for full duplex communication over a single TCP connection. WebSocket enables data exchange between the client and the server to be simpler, and allows the server to actively push data to the client. In the WebSocket API, the browser and the server only need to complete one handshake, and persistent connection can be directly established between the browser and the server, and bidirectional data transmission is carried out. Therefore, WebSocket has the advantages that: less control overhead; because the protocol is full duplex, the server can actively send data to the client at any time, and compared with the HTTP request, the HTTP request can be responded only by waiting for the client to initiate a request server, the delay is obviously less, and the real-time performance is stronger; and the WebSocket can also keep a connection state; better binary support; better compression effect.
S003, establishing connection between the UWB management program 3 and the UWB base station 2 in a UDP and Websocket double-link mode; the UWB management program 3 decodes the data after receiving the tag data information sent by the UWB base station 2, and displays the decoded data in a visual mode; the UWB management program 3 counts and arranges the received data; the labels are convenient to be managed in batches; after the processing, the data after the statistics and the arrangement are transmitted to the database 4 for storage according to a specified format.
