In a feasible implementation manner, the first transmission channel is a Bluetooth Low Energy (BLE) channel, or may be an ordinary Bluetooth channel, and it should be noted that the first transmission channel is a channel for point-to-point direct transmission, that is, the user end and the internet of things device may directly transmit data by using the first transmission channel, and do not need to forward data through other devices or sites, so that the real-time performance of data transmission is better. The first transmission channel can adopt a BLE distribution network mode, for example, the user side is in a host mode, the Internet of things equipment is in a slave mode, the user side sends a broadcast signal, and BLE connection is established with the Internet of things equipment after BLE of the Internet of things equipment is scanned to form a BLE channel, or the Internet of things equipment is in the host mode, the user side is in the slave mode, the Internet of things equipment can send the broadcast signal, and the BLE connection is established with the user side after the BLE of the user side is scanned to form the BLE channel.
In a feasible implementation manner, the second Transmission channel may be a theme of an MQTT service established based on a Transmission Control Protocol (TCP) long connection, for example, the second Transmission channel may be a "data reporting theme", "important data reporting theme", "general data reporting theme" subscribed by the internet of things device, and the internet of things device may implement data reporting by subscribing the MQTT theme of the server. It is understood that, in the embodiment of the present application, closing the second transmission channel may be understood as canceling the subscription to the related topic. It can be understood that, if the internet of things device subscribes to multiple topics at the server, there are multiple transmission channels between the internet of things device and the server.
In a feasible implementation manner, a third transmission channel may be established between the client and the server, and the third data transmission channel may be a channel established based on a Hypertext Transfer Protocol (HTTP), and may implement HTTP-based data pulling, where HTTP-based data pulling is a non-real-time data transmission mode, and may be data pulling from the server at regular time based on a certain time interval, specifically, the client sends a data pulling request to the server, and the server feeds back corresponding data to the client.
It can be understood that, in order to enable the user side, the server and the internet of things device to be in the same internet of things system, a first transmission channel can be established between the user side and the internet of things device, the user side sends wifi account information of a local area network accessed or configured by the user side to the internet of things device by using the first transmission channel, and the internet of things device accesses a corresponding internet of things system by using the wifi account information and establishes a second transmission channel.
Based on the above description, in the data transmission system, a first transmission channel is provided between the internet of things device and the user side, a second transmission channel is provided between the internet of things device and the server, and a third transmission channel is provided between the user side and the server, and further, referring to fig. 2, a schematic flow diagram of the data transmission method in the embodiment of the present invention is shown, and the data transmission method is described from the perspective of the internet of things device, and includes:
step 201, obtaining target data to be transmitted by the Internet of things equipment;
step 202, the internet of things device sends the target data to the user side through the first transmission channel, the first transmission channel is a short-distance communication channel for transmitting data between the internet of things device and the user side in real time, and the internet of things device sends the target data to the server through the second transmission channel again, so that the user side can pull the target data from the server and perform deduplication processing.
Wherein, thing networking equipment has multiple type data to thing networking equipment is the humidifier for the example, can include: the humidifier is opened and closed, and the humidifier is operated in mode data (such as sleeping, manual and automatic), and is operated in gear data, abnormal water shortage prompt data, target humidity of a user, cleaning reminding switch data, equipment model, MAC address, wifi setting and the like. It can be understood that the target data to be transmitted may be any data of the internet of things device, or the target data may be data of a designated level, specifically, the data of the internet of things device may be divided according to a preset rule, and in a feasible implementation manner, taking the humidifier as an example, the data of the humidifier may be divided into 3 priorities according to the following rule, as follows:
Figure BDA0003041701860000081
in a feasible implementation manner, different transmission modes can be selected based on the priority level of the target data, and specifically, the priority level of the target data of the internet of things device can be determined first; the method can use a dividing mode similar to the table, determine the priority level of the target data by using the data performance of the Internet of things equipment and the requirement on real-time performance, determine the relation between the priority level of the target data and the preset priority level, and determine that the target data adopts a dual-channel transmission mode if the priority level of the target data is greater than or equal to the preset priority level; and if the priority level of the target data is less than the preset priority level, determining that the target data adopts a single-channel transmission mode.
For example: if the preset priority is in the priority, when the priority of the target data is high or medium, the priority of the target data can be determined to be greater than or equal to the preset priority, and the target data can be transmitted to the user side in a dual-channel transmission mode, namely the target data is transmitted twice by using the first transmission channel and the second transmission channel, so that the real-time performance of target data transmission is improved, and the problem caused by data loss is avoided. When the priority level of the target data is low, it may be determined that the priority level of the target data is less than the preset priority level, a single transmission channel mode may be adopted, and a fourth transmission channel may be used to transmit the target data to the server, and the client pulls the target data from the server.
Further, the above dual channel transmission mode specifically includes: the internet of things equipment can utilize a first transmission channel to send target data to a user side, and can also utilize a second transmission channel to send the same target data to a server again, so that the user side can pull the target data from the server and perform deduplication processing, the same target data is transmitted through two different channels of the first transmission channel and the second transmission channel respectively, under the condition that data is lost when one channel transmits the data, the other transmission channel can also transmit the data to the user side, the probability that the data is lost and causes problems is reduced, the first transmission channel is a real-time data transmission channel, the first data transmission channel is used, and the real-time performance of data transmission can be improved.
Furthermore, after the user side pulls the data from the server each time, the pulled data can be used for carrying out deduplication processing, and waste of resource space caused by repeated storage of the same data is avoided.
In the embodiment of the application, the target data is transmitted in a dual-channel mode, so that the influence of data loss on data integrity can be reduced, and the real-time performance of data transmission can be improved.
On the basis of the embodiment shown in fig. 2, channel selection may also be implemented on the basis of dual channels, and specifically, referring to fig. 3, a flow diagram of additional steps of the data transmission method in the embodiment of the present invention is shown, including:
step 301, monitoring whether the RSSI value of the first transmission channel is greater than or equal to a preset signal strength threshold;
step 302, if it is monitored that the RSSI value is greater than or equal to a preset signal strength threshold, determining a first continuous duration for which the RSSI value of the first transmission channel remains greater than or equal to the preset signal strength threshold;
step 303, when the first duration is greater than or equal to a preset time threshold, closing the second transmission channel.
It should be noted that, in practical application, the internet of things device may perform the monitoring action in step 301, may not perform the monitoring action in step 501, and may be set according to specific needs.
In this embodiment of the application, the internet of things device may monitor a Received Signal Strength Indication (RSSI) of the first transmission channel to determine whether channel control is required.
Specifically, the internet of things device monitors whether an RSSI value of a first transmission channel is greater than or equal to a preset signal strength threshold, and if the RSSI value is greater than or equal to the preset signal strength threshold, then counts a first duration for which the RSSI value of the first transmission channel is maintained greater than or equal to the preset signal strength threshold, for example, if the RSSI value of the first transmission channel is monitored at time a to be greater than or equal to the preset signal strength threshold, then counts a first duration for which the RSSI value of the first transmission channel is maintained greater than or equal to a preset signal emphasis threshold, and if the first duration is greater than or equal to the preset time threshold, then it indicates that the first transmission channel between the internet of things device and the user terminal is relatively stable and can transmit data only by using the first transmission channel, so the internet of things device closes a second transmission channel, so that in the case that the first transmission channel is stable, the overhead of the data reporting server can be reduced in a manner of closing the second transmission channel.
It can be understood that closing the second transmission channel may specifically be to cancel subscription of an MQTT theme corresponding to the second transmission channel, and correspondingly, if the theme subscribed by the internet of things device only includes the MQTT theme corresponding to the second transmission channel, considering that the internet of things device does not send the target data from the second transmission channel any more, the user side does not need to pull the data from the server any more, therefore, the internet of things device may further send a notification message to the user side by using the first transmission channel, where the notification message is used to notify the user side that the second transmission channel is closed, so that the user side may close the third transmission channel for pulling the target data from the server after receiving the notification message, so as to further save energy consumption of the user side.
In the embodiment of the application, the internet of things device monitors the RSSI value of the first transmission channel and counts the first continuous time that the RSSI value is greater than or equal to the preset signal strength threshold, so that the second transmission channel and the third transmission channel can be controlled to be closed under the condition that the first continuous time is greater than or equal to the preset signal strength threshold, and the expenses of the internet of things device and the user side can be saved.
It should be noted that the embodiments shown in fig. 2 and fig. 3 are technical solutions described from an internet of things device, and a data transmission method will be described from a user side, please refer to fig. 4, which is another flow diagram of the data transmission method in the embodiments of the present application, and includes:
step 401, a user side receives target data sent by the internet of things device through a first transmission channel and stores the target data;
step 402, at intervals of preset pulling duration, the user side pulls the first data from the server, and performs deduplication processing on the stored data by using the pulled first data.
In this embodiment of the application, the first transmission channel is a short-distance communication channel for transmitting data in real time between the internet of things device and the user end, and may be a BLE channel, for example. The method for pulling the data from the server by the user side is to pull the data from the server at regular time, that is, the data is pulled from the server at intervals of preset pulling time duration, and belongs to a non-real-time data transmission mode.
In this application embodiment, in order to avoid the same data to save the wasted storage space repeatedly, can carry out deduplication processing to the first data of pulling, wherein, the target data that thing networking device sent has contained the timestamp at least, then utilizes first data to carry out deduplication processing to the data that have saved, include:
a. searching data which are stored by a user side and transmitted by the Internet of things equipment through a first transmission channel within a preset pulling time length, and determining whether second data with the same timestamp as that of the first data exist or not;
b. if second data with the same time stamp as the first data exists, abandoning to store the first data;
c. if there is no second data having the same time stamp as that of the first data, the first data is held.
It should be noted that, the target data sent by the internet of things device may include, in addition to the timestamp, a Media Access Control Address (MAC) Address of the internet of things device, where the MAC Address may uniquely identify the internet of things device, and when the user pulls data from the server, the sent pull request includes the MAC Address of the internet of things device.
In this embodiment of the application, after the user side pulls the first data, data transmitted through the first transmission channel by the internet of things device that is stored at the user side within a preset pulling duration is searched, for example, a time point of the last pulling is a1, a time point of the current pulling is a2, the preset pulling duration is a2-a1, the searched data is third data transmitted through the first transmission channel within the preset pulling duration from a1 to a2, and whether second data with a timestamp that is the same as that of the first data exists in the third data is determined. If second data with the same timestamp as that of the first data exists in the third data, the first data is stored, repeated storage is not needed, at this time, the first data needs to be abandoned, if second data with the same timestamp as that of the first data does not exist in the third data, the first data is lost when being transmitted through the first data transmission channel, at this time, in order to ensure the integrity of the data, the influence of the lost data is reduced, and the first data is stored.
Further, after the foregoing deduplication processing is completed, the stored data may be further integrated to further reduce the memory space occupied by the stored data, for example, the stored fourth data in the latest one or more pull times may be integrated in the following manner: and if the minute grouping interval of the data A in the fourth data is the same as the minute grouping interval of the data B, integrating the data A and the data B, setting the time stamps of the data A and the data B as preset values in the minute grouping interval, averaging other equipment data except identification data such as MAC addresses and the like, such as induction values of equipment of the Internet of things, generating new data C, deleting the data A and the data B, and replacing the data A and the data B by using the data C to complete integration and reduce the memory space required by data storage. And the integration process is executed by the user side, so that the pressure of the server on data processing can be effectively reduced, and the integration efficiency is improved.
To better understand the integration process, the following will take the data of the humidifier as an example: if the humidifier data stored by the user side contains two data, the data are respectively:
data 1 ═ timestamp: 1616134314, MAC address of humidifier BLE 24: a1:60:8C:40:86, humidity value: 0.30 };
data 2 ═ timestamp: 1616134329, MAC address of humidifier BLE 24: a1:60:8C:40:86, humidity value 0.32 };
the two data include a timestamp, a MAC address and a humidity value, wherein the timestamp is used for indicating the time of data acquisition, the MAC address is used for identifying the humidifier, the humidity value is the acquired data, the MAC addresses of the data 1 and the data 2 are the same, and therefore, the data can be determined to be the data of the same humidifier, at this time, the timestamp can be formatted to obtain minute times 2021-03-1914: 11 and 2021-03-1914: 12, the minute time values are 14 respectively, if the minute grouping interval is one group every five minutes, the data 1 and the data 2 are both in the same minute grouping interval, namely [10, 15 ], the two data can be integrated in a manner that the timestamp is set to 2021-03-1914: 00, the MAC address is unchanged, the humidity value is averaged to be 0.31, and obtaining the integrated data.
It can be understood that the data obtained by the user side after performing deduplication processing and integration processing on the data of the internet of things device can be used for data display of the internet of things device, for example, a data curve can be generated and displayed on a display interface of the user side, so that the user can view real-time data change conditions of the internet of things device.
