Detailed Description
As described above, the current schemes for estimating the remaining battery life of iBeacon transmitting devices generally have the problems of delay, high cost and low efficiency. Based on this problem, the inventors have studied to provide a method and system for estimating the remaining usage time of a battery. According to the scheme, the collection process of the battery voltage information is incorporated into the positioning process of the receiving equipment, the battery voltage information is obtained by using the identifier of the iBeacon sending equipment obtained in the positioning process, and finally the estimation of the remaining service life of the battery is realized. The scheme can effectively solve the problems.
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Method embodiment
Before describing the method for estimating the remaining battery life provided by the present application, for the sake of understanding, an application scenario of the method will be described first.
Referring to fig. 1, the application scenario of the technical solution of the present application is schematically illustrated. As shown in fig. 1, the scene includes a plurality of iBeacon transmitting devices 101, receiving devices 102, and servers 103. The receiving device 102 and the iBeacon transmitting device 101 to be estimated in the scene of the remaining battery usage duration are both located within the bluetooth communication range of the other party. The number of iBeacon transmission devices 101 in the scene for which the remaining battery usage duration is to be estimated is at least one. In fig. 1, as an example, the iBeacon transmitting device 101 in the virtual coil is an iBeacon transmitting device to be used for estimating the remaining battery usage time. The receiving device 102 is located within the bluetooth communication range of each iBeacon sending device in the virtual coil, and each iBeacon sending device in the virtual coil is located within the bluetooth communication range of the receiving device 102.
When the receiving device 102 needs to be located, the iBeacon sending device 101 may send a broadcast packet to the receiving device 102. The receiving device 102 may extract the identifier of the iBeacon sending device 101 that sent the broadcast message from the broadcast message. The receiving device 102 runs an associated Application (APP), through which the identification is forwarded to the server 103. The server 103 may be a physical server or a cloud server, and fig. 1 is a schematic view of a scene drawn by taking the cloud server as an example. The server 103 stores a correspondence relationship of "identifier-location information-received signal strength", and can determine the unique corresponding location information according to the identifier of the iBeacon transmitting device received from the receiving device 102. The location information can specifically indicate the physical location of the iBeacon sending device, thereby facilitating the location of the receiving device 102.
The flow of implementing positioning for the receiving device 102 is described above in connection with the scenario illustrated in fig. 1. In the present application, the battery voltage information of the iBeacon sending device 101 is added to the identifier of the iBeacon sending device 101, so that after the identifier of the iBeacon sending device 101 is forwarded to the server 103 from the receiving device 102, the server 103 can extract the battery voltage information of the iBeacon sending device 101 from the identifier. Using the battery voltage information, the server 103 can estimate the remaining battery life of the iBeacon transmitting device 101.
Referring to fig. 2, a flowchart of a method for estimating a remaining battery life according to an embodiment of the present disclosure is shown. The method may be implemented by a server in the scenario shown in fig. 1.
As shown in fig. 2, the method for estimating the remaining usage time of the battery includes:
step 201: and acquiring the battery voltage information of the iBeacon sending equipment from the identification of the iBeacon sending equipment.
The identity of the iBeacon sending device comprises three main parts, which are respectively: a 128-bit Universally Unique Identifier (UUID), a 16-bit primary identifier (Major) and a 16-bit secondary identifier (Minor). The manufacturer of the iBeacon sending device can allocate the above identifiers according to a self-defined protocol, and perform corresponding analysis in an application program or a server of the receiving device.
In one example implementation, a portion of the binary bits of the UUID represent battery voltage information. In another example implementation, some or all of the bits of Major represent battery voltage information. In yet another example implementation, some or all of the bits of Minor represent battery voltage information. In other implementations, the battery voltage information may also be distributed among at least two of UUID, Major, and Minor. The above manner is merely an example, and the actual application is not limited to the specific manner in which the battery voltage information exists in the identifier.
In this embodiment of the present application, the iBeacon sending device may send 3 broadcast messages on the 3 channels 37, 38, and 39 according to a preset time interval in a preset time interval. Because the broadcast messages are sent at intervals, the power consumption is low. Because the battery voltage information of the iBeacon sending equipment is contained in the identifier of the iBeacon sending equipment, the identifier carried in the broadcast message changes along with the lapse of time when the battery voltage is different. In a positioning scene, receiving equipment receives a broadcast message sent by iBeacon sending equipment, an operating application program extracts an identifier from the broadcast message, the identifier is forwarded to a server, and the server extracts battery voltage information of the iBeacon sending equipment from the identifier.
Step 202: and estimating the residual service life of the battery of the iBeacon sending equipment according to the battery voltage information.
As a possible implementation manner of this step, the server may estimate the remaining usage time of the battery of the iBeacon sending device according to the battery voltage information and the discharge characteristic curve of the battery of the iBeacon sending device. In this implementation, the discharge characteristic curve of the battery is a relationship curve between the operating voltage and the discharge time of the battery, and therefore, the remaining discharge time, i.e., the remaining usage time, of the current battery voltage can be determined from the discharge characteristic curve based on the battery voltage information.
The above is a method for estimating remaining battery life according to the embodiment of the present application. In the technical scheme, the battery voltage information required for estimating the remaining service life of the battery is integrated into the identifier of the iBeacon sending device, so that the acquisition process of the battery voltage information can be incorporated into the positioning process of the receiving device. The scheme is realized without requiring additional special equipment and without additional manual intervention to the acquisition and estimation links, so that the cost can be saved. In addition, because the frequency that the user used location service is far higher than the frequency that the special equipment was used to the special messenger to gather battery information, consequently, this application can promote the estimation efficiency to the battery remaining length of time of using through the information acquisition of high frequency correspondingly. So, be convenient for in time replace iBeacon delivery device, avoid locate function to receive the influence.
In practical application, after the iBeacon sending device is replaced, the corresponding relationship between the position information of the new iBeacon sending device and the received signal strength needs to be collected again because of the new and old differences of the devices, so as to facilitate positioning application. If the remaining service time of a battery is estimated to be too long, the position information and the strength of the received signal are replaced and collected, and the operation and maintenance efficiency is low. The present application further provides the following method on the basis of the foregoing embodiment, see fig. 3.
Fig. 3 is a flowchart of another method for estimating a remaining battery life according to an embodiment of the present disclosure. The method is still applicable to the server in the scenario shown in fig. 1. As shown in fig. 3, the method includes:
the implementation manner of the steps 301-302 is substantially the same as that of the steps 201-202 in the foregoing embodiment, and therefore the related description of the steps 301-302 can refer to the foregoing embodiment and will not be repeated herein.
Step 303: and estimating the remaining service life of the batteries of other iBeacon sending devices in the scene where the iBeacon sending device is located.
The implementation manner of estimating the remaining usage time of the battery of other iBeacon transmitting devices is substantially the same as the implementation manner of step 301 and step 302. The step may be performed simultaneously with the step 301-302, or may be performed according to a certain sequence. The order of steps shown in fig. 3 is merely an example and is not a limitation of the order of execution.
Step 304: and when the number of the iBeacon sending devices with the residual service life of the battery lower than a preset first threshold value in the scene is higher than a preset second threshold value, sending a batch replacement prompt message.
In this embodiment, the preset first threshold is a reference value for determining whether the remaining service life of the battery of the iBeacon sending device is too low. For example, the preset first threshold is 72 hours, and if the remaining service life of the battery is less than 72 hours, it indicates that the remaining service life of the battery is too low. In order not to affect the positioning function, the iBeacon transmitting device needs to be replaced as early as possible.
In this embodiment, the preset second threshold is a reference value of the number of batch replacements. For example, if the preset second threshold is 3, and the number of iBeacon sending devices meeting the replacement condition (the remaining service life of the battery is lower than the preset first threshold) is greater than 3, it indicates that these iBeacon sending devices meeting the replacement condition in the scene can be replaced in batch uniformly.
Since the server stores the corresponding relationship between the identifiers and the position information of the iBeacon sending devices to be replaced, the position information of the iBeacon sending devices to be replaced can be correspondingly determined according to the identifiers acquired from the receiving devices (possibly one or more receiving devices).
After the above determination operation is performed, the server may send a batch replacement prompt message to the central control device or the terminal device (e.g., a mobile phone or a computer) corresponding to the operation and maintenance staff. The batch replacement prompt message carries position information of all iBeacon sending devices in a scene, wherein the residual service life of the battery in the scene is lower than a preset first threshold. Based on the position information, the operation and maintenance personnel can replace the corresponding iBeacon sending equipment at the corresponding position in the past.
Therefore, operation and maintenance personnel can collect the position information of each newly-changed iBeacon sending device and the strength of the received signal in the batch replacement period, and can conveniently collect sufficient information to establish the corresponding relation between the position information of the newly-changed iBeacon sending devices and the strength of the received signal by going to the scene once. Therefore, the method can obviously improve the operation and maintenance efficiency.
In the implementation manner, the server sends the batch replacement prompt message to prompt the operation and maintenance personnel to replace the iBeacon sending equipment with the too-low residual battery service life in the scene in batch. In addition, as another possible implementation manner, the server may also separately send an alarm to the operation and maintenance personnel to the iBeacon sending device that the remaining battery life is too low. This implementation is explained below.
After the remaining battery usage duration of the iBeacon transmitting device is estimated, the method provided by the embodiment of the present application may further include:
and when determining that the residual service life of the battery of the iBeacon sending equipment is too low, sending an alarm signal. The alarm signal can be sent to the central control device or the terminal device (such as a mobile phone or a computer) corresponding to the operation and maintenance personnel by the server to give an alarm prompt to the operation and maintenance personnel, so that the battery residual service life of the iBeacon sending device is prompted to be too low. The alarm signal carries the position information of the iBeacon sending equipment. If the operation and maintenance personnel plan to replace the equipment, the equipment can go to the replacement according to the position information of the equipment.
When the step is specifically implemented, whether the remaining service life of the battery is too low can be judged by comparing the remaining service life of the battery with a preset first threshold value. When the remaining service life of the battery of the iBeacon sending equipment is lower than a preset first threshold, it is determined that the remaining service life of the battery of the iBeacon sending equipment is too low. The preset first threshold may be set according to actual requirements, and is not limited to a specific numerical value here.
In the implementation mode, the operation and maintenance personnel can autonomously judge and decide whether to carry out individual replacement or batch replacement by sending the alarm signal. In the application, the server can also provide the estimated battery remaining service time of all the iBeacon sending devices in the scene for operation and maintenance personnel, so that the operation and maintenance personnel can make an overall replacement plan by combining the battery states of all the iBeacon sending devices. For example, the remaining battery usage time of only a few iBeacon sending devices reaches below the preset first threshold, but if there are other iBeacon sending devices that will reach below the critical preset first threshold, the iBeacon sending devices may not be replaced in batch immediately, but may be replaced in batch after more iBeacon sending devices reach below the preset first threshold. Therefore, the operation and maintenance efficiency is higher, and the labor cost is further saved.
In addition, the server can estimate the remaining service life of the battery of the iBeacon sending equipment according to a certain frequency to obtain the change trend of the remaining service life of the iBeacon sending equipment. If the trend changes abnormally, for example, the trend changes extremely rapidly in a short time, the server can also determine that the power consumption of the iBeacon sending equipment is abnormal according to the trend changes.
Based on the method for estimating the remaining service life of the battery provided in the foregoing embodiment, accordingly, the present application further provides a system for estimating the remaining service life of the battery. The following description is made in conjunction with the accompanying drawings and examples.

Based on the position information carried in the batch replacement prompt message, the operation and maintenance personnel can replace the corresponding iBeacon sending equipment at the corresponding position in the past.
Therefore, operation and maintenance personnel can collect the position information of each newly-changed iBeacon sending device and the strength of the received signal in the batch replacement period, and can conveniently collect sufficient information to establish the corresponding relation between the position information of the newly-changed iBeacon sending devices and the strength of the received signal by going to the scene once.
