Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The device location synchronization method provided by the application is applied to the application environment shown in fig. 1. The first device 10 acquires the network address information of the second device, and establishes point-to-point communication of the blockchain network with the second device according to the network address information of the second device. Wherein the second device may be plural. As shown in fig. 1, the plurality of second devices includes second device 22, second device 24, second device 26, and second device 28. The first device 10 establishes point-to-point communication of the blockchain network according to the network address information of each second device. Since the first device 10 establishes the blockchain network communication with any second device, the point-to-point communication of the blockchain network can be realized between any second devices joining the blockchain network. When real-time location information synchronization between devices is achieved, when a first device 10 receives a first data request sent by a second device (which may be any second device), first real-time location information of the first device 10 is packaged into a first block, and the first block is sent to the second device in a peer-to-peer communication manner, so as to synchronize the first real-time location information to the second device. When the first device 10 sends a second data request to the second device (which may be any second device), the first device 10 receives, by means of peer-to-peer communication, a second block containing second real-time location information of the second device sent by the second device, so as to synchronize the second real-time location information to the first device 10. This way synchronization of real-time location information can be performed when any of the second devices shares real-time location information with the first device 10. It should be noted that, since point-to-point communication of the blockchain network is also established between any second devices, the real-time location information may also be synchronized between any second devices in this manner.
Specifically, the device location synchronization method may be applied in an application scenario of location information synchronization between multiple mobile IoT (Internet of Things) devices. For example, the IoT device may be a code book, a cell phone, a car pad, a smart robot, and so on. The following describes the device location synchronization method in detail based on a specific embodiment:
in this embodiment, the first device and the second device are code tables installed in vehicles, and the vehicles share the position information through the code tables. As shown in fig. 2, the first device is a code table in the vehicle 112. The second device is a plurality of second devices including a code table in vehicle 222, a code table in vehicle 224, a code table in vehicle 226, and a code table in vehicle 228. The vehicle 112 obtains the network address information corresponding to the code table in the vehicle 222, the code table in the vehicle 224, the code table in the vehicle 226, and the code table in the vehicle 228 from the code table to the server 30, and establishes a block chain network with the code tables in the vehicles. When position information sharing between vehicles is realized, point-to-point communication can be established between code tables of any two vehicles through a block chain network, and therefore synchronous sharing of real-time position information between the vehicles is realized by the equipment position synchronization method.
In one embodiment, the present application provides a device location synchronization method, which is illustrated by applying the method to the first device 10 in fig. 1. In this embodiment, the first device includes a control module, a positioning module, a display module, a power module, and a wireless module. All modules of the first device cooperate to realize the device position synchronization method. The control module is responsible for managing a network address list formed by network address information of the first device, managing a P2P (peer-to-peer) connection established by the first device, and managing node information of the first device. The positioning module is responsible for acquiring real-time position information of the first equipment by utilizing positioning devices such as a GPS chip and/or a Beidou chip. The display module is responsible for displaying the real-time position information of the first device and displaying the real-time position information of the second device acquired through the P2P connection. The power supply module is responsible for supplying power for other modules. The wireless module is responsible for network communication of the first device. The specific process of each module for implementing the device location synchronization method of the present application in cooperation refers to the execution process of each step of the device location synchronization method described below.
As shown in fig. 3, the embodiment provides a device location synchronization method, including the following steps:
s102, the first device acquires the network address information of the second device.
In this embodiment, the first device and the second device need to synchronize the real-time location information. Wherein the second device may be one or more. The first device acquires network address information of the two devices. Based on the network address information, the first device may establish network data communication with the second device. Specifically, the manner in which the first device acquires the network address information of the second device may be: the first device acquires the network address information of the second device from the server, or the local storage of the first device stores the network address information of the second device.
In one implementation, as shown in fig. 4, the second device is plural. The server 31 stores therein network address information of the first device 10 corresponding to the second device to which the device can be connected. The second device may also be referred to as a pairing device of the first device. The server 31 assigns the first device 10 a device list of paired devices. The device list includes network address information of a plurality of paired devices of the first device 10. In a specific implementation process, after the first device 10 is started, the wireless module is automatically turned on, and a communication connection is established with the server 31 through the wireless module. The control module of the first device 10 sends 31 a device connection request to the server to obtain the network address information in the network address list of the paired device. The server 31 feeds back a network address list containing network address information of the paired device to the first device 10. Therefore, the first device 10 can perform network connection with each second device according to the network address information of each second device. After the first device 10 establishes a communication connection with the corresponding second device according to the network address information of the second device sent by the server 31, a P2P (peer-to-peer) management domain is generated. Wherein the P2P regulatory domain indicates: all devices establishing a P2P connection with a device constitute a virtual area. The first device 10 may be in a point-to-point communication connection with any of the devices in the P2P administrative domain.
Further, in an implementation, when the server 31 detects that the first device 10 has established a communication connection with some second devices, the initial data of the existing group (the group of second devices that have established a communication connection with the first device 10) is fed back to the first device 10. In addition, when the server 31 detects a second device that is not in communication connection with the first device 10 and that satisfies the communication connection condition with the first device 10, it establishes a new group (a group of second devices that satisfy the communication connection condition and are not in communication connection with the first device), and feeds back initial data of the new group to the first device 10. At this time, the first device 10 receives initial data of members of the group (new group or existing group). The first device 10 may determine the network address information of each second device from the received initial data of the group members.
And S104, the first equipment establishes point-to-point communication of the block chain network with the second equipment according to the network address information of the second equipment.
In this embodiment, when the first device acquires the network address information of the second device, the control module of the first device constructs a blockchain system connected with P2P with the second device according to the network address information of the second device. That is, the first device and the second device both serve as nodes in the blockchain system. The nodes in the blockchain system communicate with each other by adopting a blockchain technology, and the communication among the nodes forms a blockchain network in the blockchain system. At this time, as a node in the blockchain system, the first device and the second device establish point-to-point communication of the blockchain network, and therefore data transmission is performed between the first device and the second device in a point-to-point communication mode in the blockchain network, so that the security of data transmission between the first device and the second device is ensured. Specifically, when there are a plurality of second devices, since peer-to-peer communication of the blockchain network is established between the first device and each second device, and both the first device and each second device serve as nodes of the blockchain system, peer-to-peer communication of the blockchain network may also be adopted between each second device. That is, each device in the P2P management domain serves as a node of the blockchain system, and the nodes communicate with each other by using the blockchain technique.
S106, the first device obtains first real-time position information of the first device.
In this embodiment, the first device obtains the first real-time location information of the first device, and specifically, the first real-time location information of the first device may be obtained by using a real-time positioning technology. Specifically, a positioning module of the first device performs real-time positioning on the position of the first device to obtain first real-time position information of the first device. The positioning module acquires first real-time position information of the first device by adopting a GPS chip and/or a Beidou chip, so that the accuracy of the first real-time position information is improved. In addition, the display module of the first device displays the first real-time position information, so that the real-time position information of the first device can be conveniently read in the first device.
And S108, when the first device receives a first data request sent by the second device, packaging the first real-time position information into a first block, and sending the first block to the second device in a point-to-point communication mode so as to synchronize the first real-time position information to the second device.
In this embodiment, the second device sends a first data request to the first device to request to acquire real-time location information of the first device. When the first equipment receives the first data request, the first real-time position information obtained through the positioning module is packaged into a first block, block chain encryption is carried out on the first block, and the encrypted first block is transmitted to the second equipment. Specifically, the first device transfers the first block to the second device in a peer-to-peer communication manner established by the first device and the second device. And the second equipment writes the first block into a local database after the safety check of the block chain node is carried out on the first block, so that the first real-time position information in the first block is extracted from the local database, and the first real-time position information is displayed in the second equipment, thereby realizing the synchronization of the first real-time position information of the first equipment. Thus, synchronizing the first real-time location information of the first device to the second device may be achieved. Meanwhile, the first real-time position information is verified by utilizing the block chain concept, so that the safety of sensitive information is improved, and information leakage is avoided.
S110, when the first device sends the second data request to the second device, the first device receives, in a peer-to-peer communication manner, the second block containing the second real-time location information of the second device sent by the second device, so as to synchronize the second real-time location information to the first device.
In this embodiment, the first device sends a second data request to the second device to request to acquire real-time location information of the second device. And when the second equipment receives the second data request, packaging the second real-time position information of the second equipment into a second block, carrying out block chain encryption on the second block, and transmitting the encrypted second block to the first equipment. The second device also includes the modules described above with respect to the first device. The second device may also obtain second real-time location information of the second device through a positioning module of the second device. And the first equipment receives the second block sent by the second equipment in a point-to-point communication mode established by the first equipment and the second equipment, and writes the second real-time position information in the second block into the local database after the safety check of the block chain node is passed. Meanwhile, when the data of the database changes, the control module sends the broadcast of the database change to each module. And the display module of the first device reads the second real-time position information of the second device and displays the second real-time position information. Thus, synchronizing the second real-time location information of the second device to the first device may be achieved. Meanwhile, the second real-time position information is verified by utilizing the block chain concept, so that the safety of sensitive information is improved, and information leakage is avoided.
In one embodiment, after step S110, the method further includes: the first equipment checks the second block according to the preset secret key, and acquires second real-time position information in the second block after the check is passed; the first device displays the second real-time location information.
In this embodiment, the first device and the second device serve as blockchain nodes, and data communication is performed between the first device and the second device by using a blockchain technology. And the first equipment carries out security verification on the second block transmitted by the second equipment according to the preset secret key. And after the verification is passed, writing the data information of the second block into a local database, and broadcasting the information of the second block which is put into the database to other modules of the first equipment. The first device can also acquire second real-time position information in the second block from the local database and display the second real-time position information to the display module, so that the real-time position information of the second device is synchronously displayed. Therefore, the real-time position information is verified by using the block chain concept, the safety of sensitive information is improved, and information leakage is avoided.
According to the device position synchronization method, the first device establishes point-to-point communication of the block chain network with the second device according to the network address information of the second device, so that decentralized point-to-point communication can be achieved between the first device and the second device, namely information communication between the first device and the second device can be achieved without information transfer of a background server. Further, when the first device receives a first data request sent by the second device, the first device packages the first real-time location information of the device into a first block and sends the first block to the second device in a peer-to-peer communication manner, so that the second device can obtain the first real-time location information synchronized with the first device in a block chain network communication manner. When the first device sends a second data request to the second device, the first device receives, in a peer-to-peer communication manner, a second block containing second real-time location information of the second device, which is sent by the second device, so that the first device can obtain, in a block chain network communication manner, the second real-time location information synchronized with the second device. Therefore, real-time position information sharing between the first device and the second device can be achieved. In addition, when the real-time position information is shared among the multiple devices, the real-time position information can be shared between any two devices by adopting the mode, so that the real-time position information can be shared among the devices in the multiple devices.
In one embodiment, before step S110, the method further includes: the method comprises the steps that first equipment obtains first real-time moving rate information of the first equipment; the first device packages the first real-time movement rate information into a third block, and sends the third block to the second device in a point-to-point communication mode, so that the second device adjusts the frequency of the first data request sent to the first device according to the first real-time movement rate information.
In this embodiment, the first device further obtains first real-time movement rate information of the first device, packages the first real-time movement rate information into a third block, and sends the third block to the second device. The first device may further pack the first real-time movement rate information and the first real-time location information together into a first block, and send the first real-time movement rate information and the first real-time location information to the second device at the same time when receiving the first data request. That is, the third block and the first block are the same block at this time. Of course, the first device may also package the first real-time movement rate information and the first real-time location information separately and transmit them separately to the second device. Further, the second device may adjust a frequency of the first data request transmitted to the first device according to the first real-time movement rate information. The adjustment mode is as follows: when it is determined that the real-time movement rate of the first device is faster according to the first real-time movement rate information, the frequency of the first data requests transmitted to the first device by the second device is greater. Therefore, the faster the first block containing the first real-time location information is transmitted from the first device to the second device, the faster the first real-time location information of the first device synchronized in the second device is. When the real-time moving speed of the first equipment is determined to be slower according to the first real-time moving speed information, the frequency of the first data request sent to the first equipment by the second equipment is smaller. Therefore, the slower the frequency of the first block containing the first real-time location information transmitted by the first device to the second device, the slower the frequency of the first real-time location information of the first device synchronized in the second device.
In a specific application scenario, when the first device and the second device move as the internet of things device, according to the fact that the higher the moving rate of the internet of things device is, the higher the frequency of writing the block into the block chain by the device serving as a node is, and the higher the frequency of updating the location information on the display module of the device is. That is, in this embodiment, the higher the first real-time moving rate of the first device is, the higher the frequency of the first data request sent by the second device to the first device is, the higher the frequency of the first real-time location information sent by the first device to the second device is, the faster the frequency of the real-time location information of the first device synchronized by the second device is, and the faster the real-time location information of the first device updated in the second device is.
For example, the following steps are carried out: the second device sends a positioning request to the first device at a default heartbeat frequency (request frequency for sending the request), and the first device transmits the real-time position information of the first device and the real-time movement rate information of the first device back to the second device. And the control module of the second device adjusts the requested heartbeat frequency according to the real-time movement rate information of the first device. Meanwhile, the real-time position information of the first device received after each request is refreshed and then displayed to the display module.
In one embodiment, step S106 includes: the first equipment acquires first real-time position information of the first equipment according to the first real-time moving rate information.
In this embodiment, the first device obtains a first real-time moving rate of the first device, and the control module of the first device controls the positioning module to obtain first real-time location information of the first device according to the first real-time moving rate. That is, when the first real-time moving rate information of the first device determines that the real-time moving rate of the first device is faster, the frequency of the first device acquiring the first real-time location information of the first device is higher. On the contrary, when the first real-time movement rate information of the first device determines that the real-time movement rate of the first device is slower, the frequency of the first device for acquiring the first real-time position information of the first device is lower. Meanwhile, after the first device obtains the first real-time position information of the first device according to the first real-time moving rate information, the first real-time position information is displayed to a display module of the first device. That is, the higher the real-time moving rate of the first device is, the faster the frequency of the acquired first real-time location information is, and the faster the frequency of displaying the updated first real-time location information in the display module of the first device is. Therefore, the first real-time position information obtained by the first equipment is more accurate, and the first real-time position information displayed in the first equipment is more accurate.
In one embodiment, step S110 is followed by: when the first device sends a second data request to the second device, the first device receives a fourth block which contains second real-time moving rate information of the second device and is sent by the second device in a point-to-point communication mode; and the first equipment adjusts the frequency of the second data request sent to the second equipment according to the second real-time moving rate information.
In this embodiment, in the second data request sent by the first device to the second device, not only the second real-time location information of the second device but also the second real-time movement rate information of the second device is requested to be acquired. And when the first equipment receives the fourth block sent by the second equipment, verifying the fourth block through the security verification of the block chain node, and storing the fourth block into the local database after the verification is passed. And the control module of the first device acquires second real-time moving rate information of the second device in the fourth block, and controls the wireless module of the first device to send the frequency of the second data request to the second device according to the second real-time moving rate information. When it is determined that the real-time movement rate of the second device is faster according to the second real-time movement rate information, the frequency of the second data requests transmitted by the first device to the second device is higher. When the real-time moving speed of the second equipment is determined to be slower according to the second real-time moving speed information, the frequency of the second data request sent to the second equipment by the first equipment is lower. Therefore, the first device can update the real-time location information of the second device according to the real-time movement rate information of the second device, so that the real-time location information of the second device synchronized to the first device is more accurate.
For example, the following steps are carried out: the first device requests the paired second device to acquire the location information of the second device at a default heartbeat frequency (e.g. 1 time/10 seconds), and the second device transmits back the real-time location information of the second device and the real-time movement rate information of the second device. And the control module of the first device adjusts the heartbeat frequency according to the real-time movement rate information of the second device, and sends a request to the second device according to the adjusted heartbeat frequency so as to request to acquire the position information of the second device. In addition, the first device refreshes the obtained real-time position information of the second device to a display module of the first device. For example, a setting of 2 m/s at the moving speed of the device corresponds to 1/10 s of the heartbeat frequency thereof. Assuming that the moving speed of the second device is 4 m/s, the heartbeat frequency of the first device sending the request to the second device is up to 1/5 s.
In one embodiment, as shown in fig. 5, before step S102, the method further includes the steps of:
s101, the first device receives detection information for detecting whether the second device meets the device connection condition for establishing point-to-point communication with the first device.
At this time, step S102 includes:
s1022: and the first equipment acquires the network address information of the second equipment when determining that the second equipment meets the equipment connection condition according to the detection information.
In this embodiment, as shown in fig. 4, the server 31 also feeds back, to the first device, detection information for detecting whether the second device satisfies a device connection condition for establishing peer-to-peer communication with the first device. That is, the first device determines whether the second device satisfies a device connection condition for establishing peer-to-peer communication with the first device according to the detection information. And under the condition of meeting the equipment connection condition, the first equipment acquires the network address information of the second equipment and establishes point-to-point communication of the block chain network according to the network address information of the second equipment. Specifically, the device connection condition in the detection information may be that a distance value between the second device and the first device is smaller than a preset distance value. Therefore, the second equipment which establishes point-to-point communication with the first equipment can be accurately screened out according to the equipment connection condition, and the accuracy of real-time position information synchronization is improved.
In one embodiment, as shown in fig. 6, after step S110, the method further includes:
and S112, the first device determines that the peer-to-peer communication between the first device and the second device is established, and disconnects the peer-to-peer communication between the first device and the second device when the second device is determined not to meet the device connection condition according to the detection information.
In this embodiment, since the first device and the second device both belong to the internet of things device in the mobile state, after the peer-to-peer communication is established, the device connection relationship between the first device and the second device may not satisfy the device connection condition, and the peer-to-peer communication between the first device and the second device needs to be disconnected. Specifically, after the first device determines that peer-to-peer communication has been established between the first device and the second device, the peer-to-peer communication between the first device and the second device is disconnected when it is determined that the second device does not satisfy the device connection condition according to the detection information. The first device may determine that the second device does not satisfy the device connection condition when determining that the distance value between the second device and the first device is greater than the preset distance value according to the detection information. At this time, the first device disconnects point-to-point communication with the second device. Therefore, the second equipment needing point-to-point communication can be determined according to the equipment connection condition, the real-time position information is synchronized to the second equipment meeting the equipment connection condition, and the accuracy of real-time position information synchronization is improved.
For the data transmission (data transmission of real-time location information and real-time moving rate information) between the first device and the second device, a specific implementation scenario is given as follows:
when the first device requests network data transmission, reducing the network request frequency can reduce the power consumption of the wireless module, but the timeliness and the accuracy of obtaining the real-time position information of the second device are ensured. Therefore, according to the characteristics of the IOT device, when the P2P manages the domain, the first device starts the positioning broadcast, updates the first real-time location information of the first device according to the first real-time moving rate information of the first device, and requests the second real-time moving rate information and the second real-time location information of the second device at a high heartbeat frequency according to the second real-time moving rate information of the second device, thereby ensuring the timeliness of data interaction with the second device. In the non-P2P administrative domain, the first device turns off the positioning broadcast, updates the first real-time location information of the first device according to the first real-time movement rate information of the first device, and updates the first real-time location information to the display module of the first device. At this time, the first device does not perform data transmission with any second device any more, and the first real-time location information updated by the first device is only used for being displayed on the display module of the first device. When the P2P regulatory domain is again established, the first device turns on the location broadcast and reestablishes data communication with the second device. Therefore, the power consumption of the first device can be reduced, and the standby time of the first device can be prolonged.
