Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that the drawback of short standby time of the tag device in the bidirectional communication of the tag device in the prior art is also the result of the practical and careful study of the applicant, and therefore, the discovery process of the aforesaid drawback and the solution proposed by the embodiments of the present application in the following description should be the contribution of the applicant to the present application in the course of the present application.
In order to solve the above-mentioned drawbacks, embodiments of the present application provide a bidirectional communication method, a control device, a communication system, and a storage medium, so that the standby time of the tag device during bidirectional communication is increased without changing a built-in battery of the tag device. The technology can be realized by adopting corresponding software, hardware and a combination of software and hardware. The following describes embodiments of the present application in detail.
First, a communication system 100 for implementing the bidirectional communication method of the embodiment of the present application is described with reference to fig. 1.
The communication system 100 may include a server 110, a gateway 120, and a tag device 130. The number of gateways 120 and tag devices 130 may be plural. The server 110 may communicate with the gateway 120, and the gateway 120 may communicate with the tag device 130 via bluetooth within a connectable range of bluetooth signals.
Wherein, tag device 130 generally refers to BLE bluetooth wearable devices such as bracelet, wrist-watch. The tag device 130 generally has broadcast, scan, and connection. Because of the large power consumed by scanning and connecting, the tag device 130 is generally in a broadcast mode for broadcasting the original data including its own tag device ID.
Gateway 120 refers to a bluetooth low energy gateway suitable for bluetooth low energy devices.
One gateway 120 may scan raw data broadcast by multiple tag devices 130 simultaneously. After the gateway 120 scans the raw data broadcast by a certain tag device 130, the bluetooth link management protocol in the bluetooth protocol stack may parse the raw data to generate the connection signal strength for communicating with the tag device 130. The gateway 120 may then generate tag device data containing the raw data, the connection signal strength between the gateway 120 and the corresponding tag device 130, and the gateway ID of the gateway 120, and send to the server 110 for use by the server 110.
A user may interact with the server 110 through the electronic device, so that the server 110 may obtain information input by the user and send the information to the gateway 120, so that the gateway 120 transmits the information to the tag device 130; or the server 110 may present the information to the user via an electronic device.
When the bidirectional communication method is performed based on the communication system 100, the tag device 130 serves to broadcast original data to the gateway; the gateway 120 is configured to scan the original data, generate tag device data according to the original data, and send the tag device data to the server 110; the server 110 is configured to obtain the tag device data, and when obtaining communication data to be sent that includes a target tag device ID, according to the target tag device ID and a target gateway; the server 110 is further configured to send the communication data to the target gateway, and issue a connection instruction to the target gateway; and the target gateway is used for establishing a connection channel with the target label equipment for data interaction when the original data broadcasted by the target label equipment is scanned again.
Of course, for the server 110 itself, when the bidirectional communication method is performed based on the communication system 100, the server 110 more plays the role of a controller to perform the bidirectional communication control method.
The server 110 may include a processor and a memory, among other things. The processor and the memory are directly or indirectly electrically connected with each other to realize the data transmission or interaction.
The memory is used for storing executable modules, for example, a program corresponding to a bidirectional communication control method appearing later or a bidirectional communication control device appearing later. Optionally, when the bidirectional communication control device is stored in the memory, the bidirectional communication control device includes at least one software functional module that can be stored in the memory in the form of software or firmware (firmware). Alternatively, the software function module included in the bidirectional communication control apparatus may be solidified in an Operating System (OS) of the server 110.
The processor is used for executing the executable module stored in the memory, and after receiving the execution instruction, the processor can execute: when communication data to be sent containing a target tag device ID are obtained, tag device data sent by the gateway are obtained, and the tag device data are obtained by the gateway based on scanned original data broadcasted by the tag device; determining target label equipment according to the ID of the target label equipment; determining a target gateway according to the target label equipment and the label equipment data; sending the communication data to the target gateway; and when the situation that the original data broadcast by the target label equipment is scanned again by the target gateway is monitored, sending a connection instruction to the target gateway so that the target gateway and the target label equipment establish a connection channel for data interaction.
The following description will be made with respect to a bidirectional communication control method provided in the present application.
Referring to fig. 2, an embodiment of the present invention provides a bidirectional communication control method applied to the server 110. The steps involved will be described below in conjunction with fig. 2.
Step S110: and when communication data to be sent containing the ID of the target tag equipment is obtained, the tag equipment data sent by the gateway is obtained.
In the embodiment of the present application, the geographic location of the gateway 120 is fixed, and the geographic location of the tag device 130 may change as the wearer moves. In addition, each gateway 120 and each tag device 130 has a unique Identification (ID).
For the tag device 130, its power consumption is on the micro-amp level when it is in the broadcast mode; when it is in scan mode, its power consumption is in milliamp level; when the device needs to be connected with other equipment, high power consumption is generated at the moment of connection, and the power consumption is reduced after the connection is finished. Therefore, in order to save power consumption and extend the standby time, the tag device 130 is generally in a broadcast mode for broadcasting the original data including the own tag device ID. Of course, other information may also be included in the raw data, including, for example, location information of the tag device 130 broadcasting the piece of raw data.
During the scanning phase, one gateway 120 may scan the raw data broadcast by different tag devices 130, for example, the raw data broadcast by tag devices 130 within the reach of bluetooth signals. It is worth noting that the bluetooth signal reach is related to distance and obstruction.
For the gateway 120, each time it scans the original data broadcasted by one tag device 130, it may generate tag device data according to the original data and its own gateway ID, and may also generate tag device data according to the original data, its own gateway ID and other data. The other data may be a connection signal strength (RSSI) between the gateway 120 receiving the raw data and the tag device 130 broadcasting the raw data, wherein the RSSI may be represented by a numerical value, and for example, a larger numerical value represents a higher connection signal strength. The bluetooth link management protocol in the bluetooth protocol stack of the gateway 120 may parse the raw data and generate the RSSI for communication with the tag device 130 broadcasting the raw data. Then, the gateway 120 obtains tag device data corresponding to the tag device 130 according to the piece of original data, the RSSI corresponding to the piece of original data, and the gateway ID of the gateway 120. Subsequently, the gateway 120 sends the tag device data to the server 110 for use by the server 110.
The server 110 may display information included in the tag device data after acquiring the tag device data. For example, when the original data includes the location information of the tag device 130 broadcasting the piece of original data, correspondingly, the tag device data sent by the gateway 120 to the server also includes the location information of the corresponding tag device 130. After receiving the tag device data corresponding to different tag devices 130, the server 110 may display the location of each tag device 130 through a display for a user to view. In this case, as an alternative embodiment, the user carrying the tag device 130 may be a patient in a hospital, and the user viewing the position of each tag device 130 may be a nurse or a doctor. As another alternative, the user carrying the tagging devices 130 may be a miner within the mine and the user viewing the location of each tagging device 130 may be a construction manager.
Of course, the above application scenarios are only examples, and it should be understood that the above examples do not limit the application scenarios in the embodiments of the present application.
In addition, when a user with management authority (for example, a doctor, a construction manager, etc. in the foregoing) needs to transmit communication data to users corresponding to a plurality of tag devices 130 or a user corresponding to one tag device 130 through the server 110, the server 110 may further obtain communication data to be transmitted input by the user with management authority, where a target tag device ID is specified in the communication data to be transmitted.
Step S120: and determining the target label equipment according to the ID of the target label equipment.
Since each piece of tag device data acquired by the server 110 includes the tag device ID corresponding to the piece of tag device data, after acquiring the target tag device ID, the server 110 may find the target tag device 130 having the tag device ID that is the same as the target tag device ID by means of matching.
Step S130: and determining a target gateway according to the target label equipment and the label equipment data.
After the target tag device 130 is determined, because the original data broadcast by one tag device 130 may be scanned by a plurality of different gateways 120, a plurality of gateways 120 that scan the original data broadcast by the target tag device 120 may also be scanned, and the server 110 may find the plurality of gateways 120 according to the tag device data including the gateway ID and the original data, and use the plurality of gateways 120 as the candidate gateways 120.
Since only one of the gateways 120 needs to be connected to the target tag device 130, one target gateway 120 needs to be determined from the candidate gateways 120.
As an alternative implementation, a target gateway 120 may be determined from the candidate gateways 120 in a random manner.
In addition, as the distance is closer, the faster the transfer speed between the bluetooth devices is, the time for information transfer can be saved, so that the time for the information receiver to be in the scanning mode can be reduced, and the energy consumption of the information receiver can be further saved. When the RSSI in the tag device data generated by a certain gateway 120 is strongest, the gateway 120 is characterized to be closest to the target tag device 130. Then, the server 110 determines the candidate gateway 120 with the strongest RSSI as the target gateway 120, so as to save the time of the target tag device 130 in the scanning mode, thereby saving energy consumption and prolonging the standby time of the target tag device 130.
In addition, the closest gateway 120 is selected for each target tag device 130, and the resources are more reasonably utilized for the entire communication system 100.
Step S140: and sending the communication data to the target gateway.
Alternatively, a routing table may be pre-stored in server 110, where the shortest path to each gateway 120 is specified. When sending the communication data to the destination gateway 120, the server 110 may first obtain the routing table, then select the shortest path to the destination gateway according to the routing table, and then send the communication data to the destination gateway 120 through the shortest path.
Step S150: and when the situation that the original data broadcast by the target label equipment is scanned again by the target gateway is monitored, sending a connection instruction to the target gateway so that the target gateway and the target label equipment establish a connection channel for data interaction.
After the server 110 sends the connection instruction to the target gateway 120, the target gateway 120 actively initiates a connection request to the target tag device 130, so that a connection channel is established between the target gateway 120 and the target tag device 130. At this point, the target tag device 130 switches to the connected mode, appearing to be awake, momentarily resulting in high power consumption, but after the connection channel is established (about 100 milliseconds are required), the power consumption returns to normal. Thereafter, the target gateway 120 sends the communication data to the target tag device 130 through the connection channel, and for the target tag device 130, the broadcasted data is transmitted to the server 110 and receives the communication data of the server 110, so as to implement the bidirectional communication function. In this process, compared to the conventional bidirectional communication, the target tag device 130 does not need to be frequently switched to the scanning mode any more, thereby avoiding high energy consumption, and thus improving the standby time of the tag device 130 during bidirectional communication without changing the built-in battery.
In addition, in the conventional bidirectional communication mode, since both the gateway 120 and the tag device 130 are constantly switching between the broadcast mode and the scanning mode, a time difference generated therebetween may cause that the tag device 130 does not receive the broadcast data through the gateway 120, and the gateway 120 does not find any broadcast data of the tag device 130 during scanning, which may result in a packet loss.
In the embodiment of the present application, a connection channel is established between the gateway 120 and the tag device 130, so that the problem of no-end waiting of the tag device 130 does not occur, and the generation of packet loss is prevented.
Of course, as an alternative implementation, after the connection channel is established, the server 110 may also obtain the interaction data sent by the target tag device 130 through the connection channel.
As an optional implementation manner, after the server 110 obtains the interactive data sent by the target tag device 130 through the connection channel, the server 110 may determine that the bidirectional communication is completed, and may further send a disconnection instruction to the target gateway 120, so that the target gateway 120 disconnects the connection channel. Because the connection channel is disconnected after the bidirectional communication is completed, the target tag device 130 is not in a connected state for a long time, and the consumption of energy consumption is reduced.
As another alternative, the target gateway 120 may actively disconnect after sending the communication data to the target tag device 120 or disconnect according to a disconnection instruction sent by the server 110 upon receiving feedback information that the sending of the communication data is completed. Wherein, the feedback information of the communication data transmission completion is fed back to the server 110 by the target gateway 120 after the communication data transmission to the target tag device 130 is completed.
According to the bidirectional communication control method provided by the embodiment of the application, when the server acquires communication data to be sent, wherein the communication data comprises a target label device ID, the label device data sent by a gateway is acquired by the gateway based on original data broadcasted by scanned label devices; determining target label equipment according to the ID of the target label equipment; determining a target gateway according to target label equipment and label equipment data; sending communication data to the target gateway; and when the situation that the original data broadcast by the target label equipment is scanned again by the target gateway is monitored, sending a connection instruction to the target gateway so as to enable the target gateway and the target label equipment to establish a connection channel for data interaction. For the target label device, the broadcasted data is transmitted to the server, and the target label device receives the communication data of the server, so that the bidirectional communication function is realized.
