Detailed Description
In order to make the objects, features and advantages of the present disclosure more comprehensible, the technical solutions in the embodiments of the present disclosure will be clearly described in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
In order to dispense with the layout of the electric wires and the network wires of the base station and reduce the construction cost when the positioning of the tag end is realized indoors, and the energy consumption of the base station needs to be reduced, an embodiment of the present disclosure provides a positioning method, as shown in fig. 1, which includes the following steps:
step 101, a wireless radio frequency signal is sent to a tag end, where the wireless radio frequency signal is used to inform the tag end whether a first ranging module of the base station is in a state to be awakened.
The tag end may be disposed on an object such as a user, a material, or a vehicle, for example only, any movable or to be positioned object may be disposed on the tag end, and the positioning is performed by using the method described in the present disclosure, and the specific disposition of the tag end on what object is not limited herein.
The base station, i.e., public mobile communication base station, is an interface device for mobile devices to access the internet, and is one form of a radio station, which is a radio transceiver station for transmitting information to and from a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. The main function of the base station is to provide wireless coverage, i.e. to enable wireless signal transmission between a wired communication network and a wireless terminal.
Thus, the base station herein can provide wireless coverage indoors (e.g., in a tunnel), and by spacing a plurality of stationary base stations, the base station can achieve substantially full coverage indoors, wherein the base stations use replaceable batteries as a power source.
The base station may transmit wireless radio frequency signals, such as bluetooth signals, RFID (Radio Frequency Identification ) signals, etc. In an example, the base station may periodically transmit a radio frequency signal (the period may be 1 HZ), and the specific period may be adjusted according to the practical application, so as to avoid the consumption of electric energy of the base station caused by long-term transmission, so that the battery service life of the base station can be prolonged.
When the first ranging module is in a state to be awakened, the first ranging module is characterized in that the first ranging module needs to be awakened to trigger starting to enter work. And when the first ranging module is in the wake-up state, the first ranging module can be directly started to work.
In an example, whether the first ranging module is in the state to be awakened is represented by the fact that the wireless radio frequency signal sent by the base station carries content representing the state, for example, the first ranging module displays a flag 0 when in the state to be awakened, and displays a flag 1 when in the state to be awakened. This is merely illustrative and is not meant to be limiting.
Step 102, if the first ranging module is in a state to be awakened, starting the first ranging module according to the request information after receiving the request information from the tag end.
According to step 101, the tag end can interact with the base station through wireless radio frequency signals, wherein each tag end has a unique tag.
Because the tag end is located at the mobile end, the energy consumption (such as battery replacement) can be conveniently supplemented, when the tag end enters the coverage area of the base station, the wireless radio frequency signal sent by the base station can be detected, and correspondingly, the tag end can also send request information (namely, the response to the base station is indicated) to the base station through the wireless radio frequency signal.
The tag receives the wireless radio frequency signal, acquires the state of the first ranging module from the wireless radio frequency signal, and if the first ranging module is in a state to be awakened, the first ranging module of the base station is closed and needs to send request information to the first ranging module under the current condition, and the base station starts the first ranging module according to the received request information.
For example, after receiving the radio frequency signal, the tag end may send 20 ms of request information to the base station and then start the first ranging module, and after receiving the 20 ms of request information, the base station starts the first ranging module.
The opening time set by the request information of different tag ends may be the same or different, the request information may not include time, and only the signal for opening the first ranging module may be transmitted, specifically adjusted according to the actual situation, and not specifically limited herein.
Therefore, if the first ranging module is in the to-be-awakened state, the base station basically belongs to the idle state before receiving the request information.
In an example, if there are at least two tag ends, i.e. there are tag end a and tag end B, it is assumed that the base station starts the first ranging module by receiving the request information from tag end a first and then receives the request information from tag end B, and then does not repeat the starting.
Step 103, if the first ranging module is in an awake state, starting the first ranging module at a first preset time after the wireless radio frequency signal is sent.
When the first ranging module is in the wake-up state, only the first ranging module is not required to be started according to the request information of the tag end, and the first ranging module is not required to be started, so that the base station is required to actively start the first ranging module.
Therefore, if the first ranging module is in the awake state, the tag end does not send the request information.
Step 104, ranging is performed by the first ranging module and the second ranging module of the tag end, so that the server locates the tag end according to the ranging result sent by the tag end.
Because the base stations are provided with a plurality of base stations, the condition that coverage areas overlap exists, and the tag end can range with the first ranging module of at least one base station through the second ranging module. According to the above-mentioned method, one base station can also correspond to a plurality of tag terminals at the same time, so that according to the above-mentioned method, the present disclosure can realize the situation that a plurality of base stations perform ranging to a plurality of tag terminals.
The first ranging module is arranged on the base station, and the second ranging module is arranged at the label end, so that the ranging is performed through the first ranging module and the second ranging module, and the distance information between the base station and the corresponding label end, namely the ranging result, can be determined.
In an example, after obtaining the ranging result, the base station turns off the first ranging module to avoid continuing to consume power. It should be understood that, because the tag end moves flexibly, the power supply can be replaced in time, and thus, the second ranging module of the tag end can be continuously started for a long time.
Preferably, the second ranging module of the tag end can also be started when needed so as to further reduce the energy consumption of the tag end. For example, the method is started when the tag end sends request information to the base station through a radio frequency signal, or is started after the tag end receives the radio frequency signal of which the first ranging module is a module to be awakened, or is started after the tag end receives a first preset time of which the first ranging module is the module to be awakened, or is periodically started (for example, 1 millisecond is started every second, and the rest time is closed), and the like, so that the method can timely range with the first ranging module. In this case, since the tag end does not need to open the second ranging module for a long time, the tag end is only opened or periodically opened according to the state of the first ranging module after receiving the radio frequency signal of the base station. Therefore, the tag end can open the wireless radio frequency module for a long time, and the second ranging module is opened according to the requirement, so that compared with the long-time continuous opening of the second ranging module, the power consumption of the tag end can be obviously reduced.
According to steps 101 to 103, the first ranging module has a wake-up state and a to-be-wake-up state, and when the tag end determines that the state information is the wake-up state, the represented signal is that the tag end does not need to send request information, and the first ranging module of the default base station is in a working state (i.e. can perform ranging with other tag ends).
In the ranging process, there may be multiple tag ends, so a first ranging module of the same base station may perform ranging with second ranging modules of multiple tag ends.
It should be appreciated that the ranging speed between the first ranging module and the second ranging module is fast, and thus, even though the time interval required for ranging between the plurality of second ranging modules and the first ranging module is small, the ranging is not affected.
In this way, the base station receives the request information of the tag end a and the request information of the tag end B, and closes the first ranging module after ranging with the tag end a and the tag end B.
In an example, the first ranging module may also determine a ranging result with the tag end, and accordingly, when ranging is completed, the base station may send the ranging result to the tag end by using a wireless radio frequency signal, so that the tag end sends the ranging result to the server by using the wireless signal. Namely, for the ranging result, the tag end can not only determine the distance information between the tag end and the base station through the second ranging module, but also receive the distance information sent by the base station.
If the tag end is located in the coverage area of two base stations at the same time, the second ranging module can determine the ranging result between the tag end and the two base stations, and can also receive the ranging results from the two base stations.
In an example, if the ranging result of the base station is received and the ranging result is determined by the second ranging module, the first ranging result (possibly determined by the second ranging module), the second ranging result determined after the first ranging result, or the like (possibly determined by the ranging information of the receiving base station) may be sent to the server, which is given by way of example.
However, since the tag end can obtain the ranging result with the base station through the second ranging module, in order to avoid the base station from performing excessive operations to consume energy, the first ranging module of the base station does not determine the ranging result and does not transmit the ranging result, and only performs corresponding operations through the tag end (i.e. determines the ranging result by the tag end), so that in order to further save the energy consumption of the base station, the ranging result is determined by the tag end and transmitted to the server. Therefore, compared with the prior art, the base station does not need to be provided with a wiring (network cable) to send the ranging result to the server, so that the cost is reduced, the continuous starting of ranging and the determination of the ranging result are not needed, the energy consumption is reduced, and the lower energy consumption can be maintained for a long time through the battery, so that the wiring of the electric wire is also not needed.
It should be understood that, because there is a situation that the tag end and more than one base station perform ranging, when the tag end sends a ranging result to the server, the method also includes sending a base station ID number corresponding to the ranging result, so that the server can determine the position of the tag end according to the preset base station coordinates, the base station ID number and the ranging result, and realize positioning of the tag end.
Based on the above scheme, the present disclosure provides a positioning method, so that in a state to be awakened, a first ranging module of a base station is in a closed state, and only when receiving request information, the first ranging module is started, so that ranging with a tag end is performed, and consumption of electric energy is greatly saved; in addition, the ranging result is determined and sent through the tag end, so that the electric energy of the base station is further saved, the base station adopts a replaceable power supply without pulling an electric wire to supply power, meanwhile, the replaceable power supply can maintain a longer service cycle due to lower consumption, in addition, the tag end sends the ranging result, the wired connection between the base station and the server through the network cable is omitted, the base station does not need to arrange the electric wire and the network cable, and the construction cost is greatly reduced.
In an example, since the tag may correspond to two base stations, the server can determine the specific location of the tag when receiving the ranging results of the tag and the two base stations.
In an example, after the first ranging module is turned on according to the request information, the method further includes:
and switching the first ranging module from a state to be awakened to an awakening state.
And when the first ranging module is in a state to be awakened, the base station starts the first ranging module after receiving the request information, and the state to be awakened is switched to the awakened state.
When the first ranging module is in an awake state, the tag end does not need to send request information, and the base station correspondingly starts the first ranging module according to the sending of the wireless radio frequency signal to enter into the preparation of ranging with the tag end. In the wake-up state, the base station does not need to judge according to the request information so as to start the first ranging module after detecting that the plurality of tag ends of the base station do not need to send the request information. Therefore, the operation and the processing performed by the base station can be further reduced, and the base station only needs to execute the starting of the first ranging module according to the state information or wait for the request information to start the first ranging module.
In an example, after the first ranging module is turned on, the method further includes:
if the first ranging module is not detected to perform ranging within the second preset time, switching the first ranging module from the awakening state to the state to be awakened, and closing the first ranging module.
In the wake-up state, the first ranging module of the base station is closed after ranging is completed, but the wake-up state of the first ranging module is unchanged, so that repeated sending of request information when a plurality of tag ends detect the base station is avoided. The base station only needs to start the first ranging module at a corresponding second preset time after each time of sending the wireless radio frequency signals, logic judgment is not needed, and ranging with the second ranging module at the tag end is achieved.
However, on the basis of the above, there is a problem that the coverage area of the base station cannot detect or has no tag end, in this case, the first ranging module cannot perform ranging operation, in order to save energy consumption of the base station, after the first ranging module is turned on, the second preset time does not perform ranging, which indicates that the base station has no tag end capable of performing ranging at this time in the coverage area of the base station, so the first ranging module is turned off, and the first ranging module is switched from the awake state to the waiting awake state, so as to save energy consumption of the base station.
The second preset time may be set to 1 minute, which is only for illustration, and may be specifically set according to practical application conditions, and is not specifically limited herein, so as to ensure the most reasonable application effect.
In an example, the first ranging module and the second ranging module are UWB (Ultra Wide Band) modules, and have the characteristics of high precision, small volume, low power consumption, and the like.
In an example, the ranging result is sent to the server by the tag end through a data transmission module. The distance measurement result is sent through the data transmission module at the label end, so that reliable data wireless transmission can be performed, and the device has the characteristics of low cost, convenience in installation and maintenance, strong diffraction capacity and long coverage range.
In one example, the wireless network communications supported by the data transfer module include 4G, 5G, or LORA to facilitate wireless transmissions indoors.
In an example, after determining the location information of the tag end, the server transmits the location information back to the corresponding tag end.
It should be understood that there may be multiple tag ends, and according to step 102, each tag end has a corresponding tag, so that the server distinguishes the received ranging result according to different tags, and returns the positioning corresponding to the different tags to the corresponding tag end.
In an example, the server may further formulate scheduling information of the tag end according to the positioning of all the tag ends, and return the scheduling information to the corresponding tag end, so as to perform scheduling in cooperation with the tag end, and improve commute or operation efficiency.
In an example, the disclosure provides a specific implementation procedure executed by the above positioning method to illustrate an interaction process between a base station, a tag end and a server, where a wireless radio frequency signal takes a bluetooth signal as an example, as shown in fig. 2, and includes the following steps:
step 201, a bluetooth signal is sent periodically.
The base station periodically transmits a bluetooth signal, and transmits the state of the first ranging module through the bluetooth signal, so that the tag end can acquire the state, and the tag end executes step 202.
If the first ranging module is in the awake state, the base station needs to execute step 206.
Step 202, detecting a bluetooth signal, and acquiring a state of a first ranging module.
The tag receives the bluetooth signal, which represents a range covered by the incoming base station signal, and it should be understood that in practical applications, the tag may start bluetooth for a long period of time to detect, obtain the state of the first ranging module, and execute step 203 or step 204 according to the state of the first ranging module. Step 203, determining that the first ranging module is in an awake state, and waiting for ranging.
The tag end determines that the first ranging module is in the wake-up state, which means that the first ranging module of the base station does not need to wake up, and only waits for the base station to actively start the first ranging module for ranging, and the tag end executes step 207.
Step 204, determining that the first ranging module is in a state to be awakened, and sending request information.
If the tag end determines that the first ranging module is in the to-be-awakened state, it indicates that the first ranging module of the base station needs to be awakened and then turned on, so that the tag end sends request information to the base station, and the base station executes step 205.
It should be understood that step 203 and step 204 are two steps in parallel, and thus are not performed sequentially.
Step 205, receiving the request information, starting the first ranging module according to the request information, and switching the first ranging module from the state to be awakened to the awakened state.
After receiving the request information from the tag end, the base station starts the first ranging module according to the request information, and switches the first ranging module from the to-be-awakened state to the awakened state after starting, so that the switching of the state of the first ranging module is caused by starting the first ranging module, the tag end executes step 207, and the base station can also execute the ranging operation of the first ranging module and the second ranging module in step 207.
In step 206, in the awake state, the first ranging module is turned on for a first preset time after the bluetooth signal is transmitted.
For the base station, if the first ranging module is in an awake state, the base station actively starts the first ranging module at a first preset time after sending a bluetooth signal to the tag end.
In this state, if there is a tag end, the first ranging module and the second ranging module perform ranging, so the tag end performs step 207; if the tag end does not exist, the first ranging module does not perform ranging with the second ranging module within the second preset time, so the base station executes step 210 to switch the first ranging module from the awake state to the to-be-awake state, and closes the first ranging module to save energy consumption.
In step 207, the first ranging module and the second ranging module range, and determine the ranging result.
And the tag end starts Bluetooth for a long time, and starts the second ranging module according to the received state of the first ranging module. After the first ranging module of the base station is turned on, the second ranging module may perform ranging with the first ranging module (both the base station and the tag end perform the action), determine a ranging result, and after determining the ranging result, make the base station perform step 208 and the tag end perform step 209, where step 208 and step 209 are performed in no order.
Step 208, the ranging is completed, and the first ranging module is turned off.
In order to save the energy consumption of the base station, when the ranging is completed, the base station turns off the first ranging module, and because the first ranging module is switched from the to-be-awakened state to the awakened state in step 205, the base station continues to execute step 206, and turns on the first ranging module at a first preset time after the base station transmits the bluetooth signal.
Step 209, uploading the ranging result to the server through the wireless signal.
The tag end uploads the ranging result to the server through the wireless signal, and the server performs step 211.
Step 210, the first ranging module is switched from the awake state to the awake state, and the first ranging module is closed when the ranging is not performed within the second preset time.
When the first ranging module is in the wake-up state, the first ranging module is periodically and circularly started according to the transmission of the Bluetooth signal, so that in order to save energy consumption when the tag end is not detected, ranging is not performed after a second preset time, the first ranging module is switched from the wake-up state to the to-be-awakened state, and the first ranging module is closed.
Thus, when the bluetooth signal is sent again, the first ranging module is in a state to be awakened, and thus the base station can execute step 201.
Step 211, positioning the label end.
After receiving at least one ranging result from the tag end, the server determines the position information of the tag end according to the ranging result.
After determining the position information of the tag end, the server may also send the position information to the corresponding tag end.
