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.
Fig. 1 is a flowchart of a control method of a battery switch according to the present application, as shown in fig. 1, where fig. 1 includes:
101. uploading the reported data to a gateway;
it should be noted that, in the present application, a battery switch with low power consumption may be adopted, and a wireless transmission technology is adopted to implement interaction between the battery switch and the server. The interaction process between the battery switch and the gateway and the server is specifically as follows: firstly, the battery switch sends the reported data to the gateway, wherein the gateway and the battery switch as well as the gateway and the server do not need to be relayed.
102. The gateway replies a confirmation character after receiving the reported data and sends the reported data to the server;
it should be noted that, after the gateway receives the reported data uploaded by the battery switch, the gateway can reply a confirmation character to the battery switch, so that the battery switch recognizes that the gateway has received the data; meanwhile, the gateway can upload the reported data to the server, so that the server feeds back corresponding instruction data according to the reported data.
103. Entering a dormant state after receiving the confirmation character, and waiting for uploading reported data next time;
it should be noted that the switch battery enters the sleep state after receiving the confirmation character fed back by the gateway, so that the battery switch can save energy and power as much as possible, the service life of the switch battery is prolonged, the battery switch sends the report data to the gateway again until the next trigger data appears in the switch battery, and at this time, the battery switch is activated again. The trigger data in the present application may be trigger data of a switch scene key.
104. And when the gateway receives the downlink data issued by the server, the gateway stores the downlink data until the reported data is received again, and the gateway packs and replies the confirmation characters and the downlink data.
It should be noted that, when the gateway receives downlink data (the downlink data may be instruction data corresponding to reported data, for example, instruction data corresponding to key trigger data) sent by the server, the gateway first stores the downlink data; and when the battery switch is activated and the report data is sent, the gateway packs the downlink data and the confirmation characters and feeds the packed downlink data and the confirmation characters back to the battery switch to complete the interaction process between the battery switch and the server. The interaction process of the specific battery switch and the server can refer to the content shown in fig. 2.
This application discerns the interaction that realizes battery switch and gateway through the affirmation character of battery switch to the gateway feedback, when the battery switch triggers the report data once more, the gateway sends the instruction data and the affirmation character packing of server feedback for battery switch, and at this in-process, battery switch most time maintains dormant state for reduce battery switch's energy consumption, increase battery switch's life. In addition, the problem that traditional wired intelligence switch reforms transform difficultly has been solved to the wireless transmission scheme of exempting from to lay wire of this application.
The present application also provides another embodiment of a control method of a battery switch, as shown in fig. 3, where fig. 3 includes:
201. uploading the reported data to a gateway, and opening a receiving window with a preset time length; after receiving the reported data, the gateway replies a confirmation character and downlink data;
it should be noted that, in the present application, a time window with a preset time length may be set, so as to wait for the gateway to feed back the confirmation character and the downlink data, and avoid waiting for the battery switch for a long time, so that the battery switch is in a sleep state for most of the time, and avoid power consumption.
202. If the receiving window receives the confirmation character and the downlink data, entering a dormant state and waiting for uploading the reported data next time; if the confirmation characters and the downlink data are not received in the receiving window, uploading the reported data again after the preset time length is exceeded;
it should be noted that, when the battery switch receives the confirmation character and the downlink data in the receiving window with the preset time length, it indicates that the interaction between the battery switch and the server is completed, and at this time, the battery switch enters a sleep state, so that the consumption of electric energy is reduced; if the battery switch does not receive the confirmation characters and the downlink data in the receiving window with the preset time length, the reporting data can be uploaded again after waiting for the preset time length, the reporting data is sent for multiple times, and the feedback of the gateway is waited. The method waits for the gateway to respond to an ACK (Acknowledge character) signal within a set time period, and is used for stopping the current sending timeout waiting; and waiting for the gateway to respond to the ACK signal within a set time period so as to terminate the current retransmission mechanism.
203. Step 201 and step 202 are repeated, if the confirmation character and the downlink data are not received within the preset uploading times, it indicates that the communication interaction fails, and the communication system directly enters into the sleep state.
It should be noted that, by repeating step 201 and step 202, the present application may set a certain number of uploading times to wait for the feedback of the gateway, and if the preset number of uploading times is exceeded, the battery switch directly enters the sleep state in order to reduce the power consumption of the battery switch. According to the method and the device, the battery switch is provided with the receiving window with the preset time length and sends the reported data for multiple times at intervals with the preset time length, so that the battery switch can respond quickly, and the power consumption of the battery switch can be reduced. The interaction process of the specific battery switch and the gateway server can refer to the interaction sequence chart shown in fig. 4.
According to the method and the device, the battery switch is provided with the receiving window with the preset time length and sends the reported data for multiple times at intervals with the preset time length, so that the battery switch can respond quickly, and the power consumption of the battery switch can be reduced. In addition, the battery switch is in a dormant state most of the time, and the battery switch with low power can be adopted in the application, for example, the battery switch with the lowest power consumption of 2uA can be adopted, so that the service life of the battery switch with low power consumption can be greatly prolonged, namely, the battery switch of the scheme can reduce the replacement times of the battery and increase the use satisfaction of a user.
In a specific application example, the application modifies the CLASS a mode in LoRaWAN, so as to implement interaction between the battery switch and the gateway and the server, where a specific interaction timing chart is shown in fig. 5, and includes:

301. the battery switch uploads the reported data to the gateway and opens a 100 millisecond receiving window; after receiving the reported data, the gateway replies a confirmation character to the battery switch and uploads the reported data to the server;
302. if the battery switch receives the confirmation character in the receiving window of 100 milliseconds, the battery switch enters a dormant state and waits for uploading the reported data next time; if the confirmation character is not received in the receiving window of 100 milliseconds, uploading the reported data again after the time of 100 milliseconds is exceeded;
303. and repeating the step 301 and the step 302, wherein if the battery switch does not receive the confirmation character within the preset uploading times, the communication interaction fails at this time, and the battery switch directly enters the sleep state.
It should be noted that, in the method for implementing modified LoRaWAN-based battery switch control, the battery switch and the gateway use the LoRa spread spectrum technology as the physical layer transmission technology; the link layer between the battery switch and the gateway is realized by using a LoRaWAN protocol synchronization technology; the battery switch modifies the CLASS a mode in LoRaWAN. A large number of experimental conclusions verify that the transmission parameters of the intelligent battery switch based on the LoRaWAN protocol framework are finally suitable for being realized, so that the intelligent battery switch based on the LoRaWAN protocol framework can achieve a millisecond-level response mechanism, the requirement of daily family on quick response is met, and meanwhile, the performance is better than that of other communication modes. On the basis of meeting the quick response, the communication distance of the battery switch can reach more than 500 meters, and the use and transformation requirements of the intelligent home under the condition of not using the repeater can be met.
In a specific embodiment, the system framework of the modified LoRaWAN battery switch is shown in fig. 8, where fig. 8 includes:
