Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Because UWB realizes the location through launching and accepting the nanosecond or below the nanosecond pulse, the work power consumption is big, on average more than tens of mA, lead to UWB to fix a position the power consumption higher, this application has provided a location method, system and storage medium, can effectively reduce UWB, for easy understanding, the following will describe this application in detail.
Referring first to the flowchart of a positioning method shown in fig. 1, the method mainly includes the following steps S102 to S112:
step S102, scanning Bluetooth broadcast signals;
step S104, if the Bluetooth broadcast signal is scanned, judging whether the Bluetooth broadcast signal carries identification information of a target base station;
step S106, if the Bluetooth broadcast signal carries the identification information of the target base station, analyzing the Bluetooth broadcast signal to obtain an analysis result, wherein the analysis result comprises: control instructions or target UWB parameters, the target UWB parameters comprising at least one of: positioning period, channel, pulse repetition frequency, preamble length, PAC size, sending and receiving message code, standard or non-standard SFD, transmission rate, PHR mode and SFD overtime time of the UWB chip;
step S108, if the analysis result is the control instruction, controlling the working state of the UWB chip based on the control instruction;
it should be noted that, the positioning chip resets the UWB chip and turns off the power supply thereof, so that the UWB chip stops working, thereby saving power consumption.
Step S110, if the analysis result is the target UWB parameter, judging whether the target UWB parameter of the UWB chip is the same as the current UWB parameter of the UWB chip;
and step S112, if the target UWB parameters of the UWB chip are different from the current UWB parameters of the UWB chip, controlling the UWB chip to work according to the target UWB parameters.
It should be noted that the bluetooth broadcast signal may also carry information such as a positioning period of the UWB chip, a channel, a pulse repetition frequency, a preamble length, a PAC size, a transmission and reception message code, a standard or non-standard SFD, a transmission rate, a PHR mode, and an SFD timeout time. Since there are areas where there are special regulations regarding UWB channels, allowing only dedicated channels, such as only channel 5 and channel 7 in china, UWB communication channels can be modified remotely without requiring modification by each device. Meanwhile, the positioning distance of UWB positioning has a certain relation with the parameters, for example, when the positioning tag device works in a close range, the positioning range can be reduced by changing the parameters, and the power consumption is reduced. In expanding the positioning range, the positioning range may be naturally increased by increasing the modified preamble, PAC, transmission rate, and the like. In addition to the fixed parameters, a specific protocol may be agreed, and in the present application, if the bluetooth broadcast signal includes agreed parameters, the UWB parameters may be changed or the direct sleep may be performed.
In addition, it should be further noted that the positioning chip scans the Bluetooth broadcast signal by using a BLE (Bluetooth Low Energy) technology, so as to further reduce the positioning power consumption.
By the mode, UWB parameters of the UWB can be modified in real time, the working state of the UWB can be changed, and the UWB can periodically enter a dormant state, so that the purpose of reducing power consumption is achieved.
In one implementation, the method further comprises the steps of:
step S202, if the Bluetooth broadcast signal does not carry the identification information of the target base station, judging whether the Bluetooth broadcast signal carrying the identification information of the target base station is scanned within a preset time;
step S204, if the Bluetooth broadcast signal carrying the identification information of the target base station is not scanned within the preset time, controlling the UWB chip to stop working;
step S206, if the Bluetooth broadcast signal carrying the identification information of the target base station is scanned within the preset time, controlling the UWB chip to work according to the target UWB parameters and/or the control instruction.
In this application, it should be noted that the preset time may be set by a user according to actual situations, and is not specifically described in the embodiment of the present invention, and generally, the preset time is preferably 30 seconds.
The positioning tag judges whether a Bluetooth broadcast signal carrying identification information of the target base station is scanned within a preset time.
If the Bluetooth broadcast signal carrying the identification information of the target base station is not scanned within the preset time, the positioning tag is out of the positioning range, and therefore the positioning tag can control the UWB chip to stop working.
And if the positioning chip scans the Bluetooth broadcast signal carrying the identification information of the target base station within the preset time, controlling the UWB chip to work according to the target UWB parameters and/or the control instruction.
Through the mode, when the positioning tag moves out of the positioning range, the UWB positioning power consumption can be further reduced.
In one implementation, the method further comprises the steps of:
and S208, if the UWB parameters of the UWB chip are the same as the current UWB parameters of the UWB chip, controlling the UWB chip to work according to the current UWB parameters.
As shown in fig. 2, the present application further provides another positioning method applied to a base station, where the method includes the following steps:
step S302, obtaining Bluetooth broadcast parameters input by a worker, wherein the Bluetooth broadcast parameters comprise; a control instruction or a target UWB parameter, wherein the control instruction is an instruction for controlling an operating state of the UWB chip, and the target UWB parameter includes at least one of: positioning period, channel, pulse repetition frequency, preamble length, PAC size, sending and receiving message code, standard or non-standard SFD, transmission rate, PHR mode and SFD overtime time of the UWB chip;
step S304, judging whether the Bluetooth broadcast parameters input by the staff are the same as the current broadcast parameters of the base station;
step S306, if the Bluetooth broadcast parameters input by the staff are different from the current broadcast parameters of the base station, generating a new Bluetooth broadcast signal based on the Bluetooth broadcast parameters input by the staff, and broadcasting the new Bluetooth broadcast signal.
As shown in fig. 3, the method further comprises the steps of:
step S308, if the Bluetooth broadcast parameters input by the staff are the same as the current broadcast parameters of the base station, broadcasting the current Bluetooth broadcast signals.
In this application, the base station is responsible for broadcasting bluetooth broadcast signal, carries control command or target UWB parameter in the bluetooth broadcast signal, wherein, control command is the instruction that is used for controlling the operating condition of UWB chip, target UWB parameter includes following at least one: positioning period, channel, pulse repetition frequency, preamble length, PAC size, sending and receiving message codes, standard or non-standard SFD, transmission rate, PHR mode and SFD timeout time of the UWB chip. Since the base station uses an external power source regardless of power consumption, a broadcasting operation of the bluetooth broadcast signal is always performed with a broadcasting time interval of less than 30 ms.
In addition, it should be noted that the base station establishes a network connection with the background server, and the user can change the information carried in the bluetooth broadcast signal of the base station through background operation.
For example, a parameter for decreasing the increased positioning range and a parameter for changing the UWB parameter may be generated by user settings. The dormancy of the tag can be forcibly stopped through user operation when the positioning is not needed, and the tag can also automatically enter the dormancy until the tag enters the positioning range or moves again and is awakened again by receiving the signal intensity of the Bluetooth broadcast signal of the base station so as to judge that the tag exceeds the positioning range or stays somewhere for a long time.
