101. receiving downlink data issued by a server through a gateway, wherein the downlink data cannot be received if a single fire switch is in a dormant state; the single-fire switch enters a receiving state of a preset second time interval after entering a dormant state of the preset first time interval;
it should be noted that, when the server issues data to the single fire switch, the server first issues data to the gateway, and the gateway sends the data to the single fire switch, if the single fire switch is in a dormant state, downlink data cannot be received, and the data cannot be received until the single fire switch is in a receiving state.
102. If the single fire switch is in a receiving state, the single fire switch immediately returns the confirmation character and the report data to the gateway after receiving the downlink data, and immediately enters a dormant state after returning the confirmation character and the report data.
It should be noted that, when the single fire switch is in the receiving state, the single fire switch receives the downlink data, immediately returns the confirmation character and the report data to the gateway after receiving the downlink data, and immediately enters the sleep state after returning the confirmation character and the report data, so that the single fire switch can reduce the receiving time, thereby reducing the power consumption of the battery of the single fire switch, and ensuring the long endurance of the single fire switch with low power consumption. And because the single live switch has a receiving state for a certain time after each sleep period, the single live switch can ensure the real-time interaction between the single live switch and the server.

Fig. 2 is another embodiment of a single fire switch control method according to the present application, where fig. 2 includes:
201. receiving downlink data issued by a server through a gateway, wherein the downlink data cannot be received if a single fire switch is in a dormant state; the single-fire switch enters a receiving state of a preset second time interval after entering a dormant state of the preset first time interval;
202. if the single fire switch is in a receiving state, the single fire switch immediately returns the confirmation character and the report data to the gateway after receiving the downlink data, and immediately enters a dormant state after returning the confirmation character and the report data.
203. If the single fire switch cannot receive the downlink data within the preset second time interval of the whole receiving state, the gateway continuously sends the downlink data to the single fire switch until the single fire switch enters the receiving state again;
it should be noted that, when the gateway issues downlink data to the single fire switch, if the single fire switch is in the dormant state, the gateway may continuously issue data to the single fire switch (at this time, the single fire switch does not consume power, and the data issued by the gateway is quickly received after the dormant state is ended), and when the single fire switch enters the receiving state, the downlink data is immediately received, so that the real-time performance of data interaction between the single fire switch and the server is ensured.
204. And the single fire switch immediately returns the confirmation character and the reported data to the gateway after receiving the downlink data, and immediately enters a dormant state after returning the confirmation character and the reported data.
It should be noted that the one-fire switch can immediately return the confirmation character and the report data to the gateway after receiving the downlink data, so that the one-fire switch can complete the data reception and feedback in the reception state, and immediately enter the sleep state after returning the confirmation character and the report data, thereby ensuring the long endurance of the one-fire switch battery.
205. If the interval time from the end of the receiving state is less than the preset third time interval when the single fire switch finishes receiving the downlink data, the preset second time interval of the current receiving state is prolonged to the preset fourth time interval;
it should be noted that, in order to ensure that the one fire switch can feed back data in time to ensure real-time data interaction, a difference between a time point when the one fire switch finishes receiving the downlink data and a time point when the receiving state ends may be determined, and the difference may be compared with a preset third time interval (the preset third time interval may be set according to a time required for data reporting), and when the difference is smaller than the preset third time interval, the preset second time interval of the current receiving state is extended to a preset fourth time interval, for example, from 100ms to 150ms, so that the one fire switch may finish uploading the reported data in the preset fourth time interval.

it should be noted that, in order to reduce the battery consumption, the one-fire switch may enter the sleep state immediately after the confirmation character and the report data are replied within the preset fourth time interval.
207. And if the single fire switch does not finish replying the confirmation character and the reported data in the preset fourth time interval, immediately entering a dormant state after the preset fourth time interval is finished.
It should be noted that, if the one-fire switch still does not complete sending of the reported data within the preset fourth time interval, the one-fire switch needs to be forced to enter the sleep state at this time, so as to ensure the continuous working performance of the one-fire switch.
This application is through the dormant state and the receipt state of rational distribution single fire switch for, single fire switch can maintain shorter receipt state and longer dormant state always, when making single fire switch can guarantee the long continuation of the journey of low-power consumption, maintains higher real-time, thereby guarantees single fire switch's use satisfaction.
An interaction timing diagram of another embodiment of a single fire switch control method of the present application is shown in fig. 3.
The above is an embodiment in which the server issues data to the single fire switch, and the present application also includes an embodiment in which the single fire switch uploads reported data to the server, and an interaction timing chart of the embodiment is shown in fig. 4, and includes: uploading reported data to a gateway by a single fire switch, and opening a receiving window with a preset time length; after receiving the reported data, the gateway replies a confirmation character and downlink data to the single fire switch; the single fire switch receives the confirmation character and the downlink data in the receiving window, enters a dormant state and waits 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; after the reported data is uploaded twice, the single fire switch can enter a dormant state no matter the confirmation character and the downlink data are not received.
In a specific embodiment, the application adopts a modified LoRaWAN-based simplex switch control method, and implements an interaction process between a server and a simplex switch by using CLASS a and CLASS C modes modified by LoRaWAN, as specifically shown in fig. 5. In this embodiment, the modulation spreading factor SF may be set to 7, and the bandwidth BW may be set to 500 KHz. In the data reporting stage of the single fire switch, the response time of waiting for the gateway to reply the confirmation characters after the single fire switch sends the uploaded data is 30 ms; if the confirmation character replied by the gateway is received within 30ms after the single fire switch reports the data again, the gateway enters a dormant state; if the confirmation character is not received within 30ms, the reported data is sent to the gateway again after 30ms, and the gateway enters a sleep state after 30 ms. And after the gateway receives the reported data of the single fire switch again, the gateway packs the downlink data and the confirmation characters and replies.
And a stage of sending downlink data to a single fire switch at a server: the receiving state time of the single fire switch is 100ms between the receiving state and the sleep state. When downlink data sent by a server is transmitted to a single fire switch through a gateway, if the single fire switch is in a receiving state, the single fire switch immediately returns a confirmation character after receiving the downlink data and enters a sleep state after returning the confirmation character, wherein the duration time of the sleep state is 320 ms; if the downlink data sent by the server is transmitted to the single fire switch through the gateway, the single fire switch is in a dormant state, and the single fire switch cannot receive the downlink data; if the single fire switch cannot receive the downlink data within the interval of the preset receiving time of the whole receiving state, the gateway continuously sends the downlink data to the single fire switch until the single fire switch enters the receiving state again, after the single fire switch receives the downlink data, the single fire switch returns the confirmation characters and reports the data to the gateway, and after the confirmation characters are returned, the gateway immediately enters the dormant state.
In a specific implementation mode, when the fact that the dormant state of the single fire switch is about to end is detected, the single fire switch is still in a stage of returning confirmation characters and reported data, the receiving state is prolonged by 50ms, and if the confirmation characters and the reported data are uploaded within 50ms, the single fire switch immediately enters the dormant state after the confirmation characters and the reported data are uploaded; if the character is confirmed and the reported data are not uploaded within 50ms, the mobile terminal enters a dormant state after the 50ms is finished.
A program flow diagram of one embodiment of the present application is shown in fig. 6, and includes:
and the single fire switch inquires whether a key is pressed down or whether downlink data issued by the server is received in real time. If the key is detected to be pressed, the shaking is removed for 100ms, whether the key is pressed is detected again, if the key is still pressed, the key is pressed effectively, and otherwise, the key is invalid. And when the key is effective, triggering and judging whether the scene key is triggered or the entity loop key is triggered or the linkage double-control key is triggered. If the linkage double-control key is triggered, the physical loop relay is not actuated, because the relay consumes power. Judging whether the key is pressed for a long time or pressed for a short time, and if the key is pressed for the long time, canceling the current linkage state; and if the short press is carried out, the data is packaged and uploaded to the server at the moment, and then the terminal equipment responding to the data is controlled in a linkage mode. If the key is an entity loop key, firstly judging whether the switch is pressed for a long time or pressed for a short time, and if the key is pressed for the long time, judging to cancel the current entity loop so that the key switch is switched to a linkage control switch; if the short press is detected, the relay of the physical loop is actuated to perform on and off actions, and the current state of the loop is reported to the server, so that the data synchronization of the local switch and the server is realized. If the scene key is pressed, judging whether the key is pressed for a long time or pressed for a short time, and if the scene key is pressed for a long time, resetting the whole switch; and if the short press is carried out, directly packaging the corresponding scene loop data and reporting the scene loop data to a server, and then triggering the previously set scene control. If the data reception is detected, the data is analyzed according to a specific protocol and whether the switch is operated or not is determined, and corresponding response data is sent to the server. Therefore, switch linkage control and direct local switching of the entity loop are realized, and remote linkage and switching of the entity loop are supported according to the corresponding protocol.
In one embodiment of the present application, a low power consumption and real-time control combined program flow diagram; as shown in fig. 7, includes:
when the single fire switch is in a receiving state (wakeup)100ms state, whether data needs to be sent or not is inquired all the time, and if not, the state is up to a state that a sleep state (sleep) is needed to be entered 320 ms. If the data is found to be transmitted at this time, the type of the data is inquired. If the data type is keying data, sending confirmation data (confirm data), and if receiving a confirmation character ACK replied by the gateway, waiting to enter a dormant state; if not, the single fire switch retransmits the data, and if the retransmission data reaches twice, the sleep state is waited to enter. And if the data bit response server controls the query data, sending unconfirmed data, and directly entering a state waiting for entering a sleep state without retransmitting after the sending is finished. In order to ensure that data can respond to the server in time, the data needs to be replied immediately after the server data is received, unlike the situation that the key data can be transferred to the next report. Therefore, in order to ensure that data can be normally transmitted without being limited by 100ms wakeup time and 320ms sleep time, 50ms wakeup time needs to be added to the original 100ms wakeup time. Of course, the increase of 50ms requires consideration of the power supply capability of the one-fire switch, so that once transmission is completed within 50ms, the sleep state is directly entered, and the lamp 50ms is not required to be completely completed. If the transmission is still not finished after 50ms, the one-fire switch needs to be forced to enter a sleep state at the moment so as to ensure the continuous working performance of the one-fire switch. The diagram shows the whole single live switch data transmission process and the implementation process of low power consumption and real-time response receiving.
In a specific embodiment, the system framework of the modified LoRaWAN battery switch is shown in fig. 10, where fig. 10 includes:
STM32G030C8T6, ASR6500SLC driver, key driver, LED driver, UART driver, receiving and transmitting mechanism for correcting CLASS A mode in LoRaWAN and receiving and transmitting mechanism for correcting CLASS C mode are combined, LLCC68 (Internet of things wireless communication spread spectrum module) of SEMTECH company or ASR6500SLC (LoRa wireless communication radio frequency chip) of ASR is adopted, the performance is superior to SX1278, the sending distance is longer, the sending power consumption and the receiving power consumption are lower, and the service life of the battery switch product is longer. Wherein PWM-pulse width modulation; UART-asynchronous transceiver transmitter, SPI-serial peripheral interface protocol, RTC-real time clock. The keys comprise entity loop keys and scene keys, and comprise various combination modes, such as a 1 entity loop +1 scene, a 2 entity loop +2 scene, a 3 entity loop +3 scene, a 3 entity loop +1 scene and the like. The entity loop can be set as a linkage double-control switch, and the switch has various combinations, so that various combination modes of the linkage double-control switch, the entity loop switch and a scene key are realized, the specific combination mode is not particularly specified, and the linkage double-control switch, the entity loop switch and the scene key can be set through a server according to a predefined communication protocol, so that the remote setting of functions of linkage double control and scene increase, deletion, modification and lamp searching is realized. Local switching and remote switching between the local linkage key and the entity loop key are also realized.
The present application further provides a method for controlling a battery switch, which is based on a CLASS a transceiving mechanism modified by a LoRaWAN protocol, wherein a flow chart of data enqueuing is shown in fig. 8, where fig. 8 includes:

it should be noted that, when the data sent by the battery switch is blocked due to factors such as waiting for the gateway to reply an acknowledgment character or retransmitting the acknowledgment character after time out, and the like, and at this time, when the key is pressed again or another key is pressed, newly generated data needs to be temporarily stored to ensure the continuity and reliability of the data. Therefore, the current network state needs to be detected.
302. When network congestion is detected, a newly generated data mark to be uploaded is inquired in real time;
it should be noted that when network congestion is detected, at this time, when a key is pressed again or another key is pressed, newly generated data caused by the key can be queried in real time, and since the network congestion is at this time, data of a trusted product can be stored locally.
303. If the newly generated data mark to be uploaded is inquired and the temporary storage queue is not fully loaded, storing the newly generated data to be uploaded into the temporary storage queue according to the first-in first-out sequence and updating the state of the temporary storage queue;
it should be noted that a plurality of temporary storage queues may be locally constructed, and are used to store newly generated data to be uploaded, and to eject the stored data in time when the network is restored. Specifically, when a mark of newly generated data to be uploaded is detected, whether the temporary storage queue is fully loaded at the moment is detected, if the mark is not fully loaded, the newly generated data to be uploaded are stored into the temporary storage queue according to a first-in first-out sequence, and the temporary storage queue after the newly stored data is updated.
304. If the data to be uploaded mark is inquired and the queue is full, stopping the ongoing retransmission timeout timing, clearing the waiting confirmation character, and covering the data to be uploaded with the earliest data in the temporary storage queue.
It should be noted that, when the to-be-uploaded data flag is found, if the temporary storage queue is fully loaded at this time, the ongoing retransmission timeout is stopped, the waiting acknowledgement character is cleared, and the to-be-uploaded data is overwritten on the earliest data in the temporary storage queue. Specifically, the method can set a temporary storage first-in first-out queue QueueA with the length of 5, and enqueue newly generated data. The maximum 5 times can be carried out in sequence, and when the number of times of data needing to be enqueued exceeds the set maximum number of times, a mode of covering old data is adopted at the moment so as to ensure the accuracy of the latest state of the data.

401. inquiring whether a data sending mark exists;
it should be noted that, when the network condition is recovered, it may be queried whether a data transmission flag exists.
402. If the data to be uploaded exists, popping the data to be uploaded out of a temporary storage queue according to a first-in first-out principle, sending the data to be uploaded to a gateway, and updating the state of the current temporary storage queue;
it should be noted that, when there is a data sending flag, data to be uploaded may be popped out of the temporary storage queue according to a first-in first-out principle, that is, the earliest queued data in the temporary storage queue is popped out of the temporary storage queue and sent to the gateway; updating the state of the current temporary storage queue; at this time, the data in the temporary storage queue can be sequentially sent, and the data in the temporary storage queue is sequentially popped up and sent according to the first-in first-out principle, so that the fact that all the data in the temporary storage queue are sent is known.
403. Inquiring whether a confirmation character is received, if so, returning to the step 401;
it should be noted that, whether the battery switch receives the confirmation character returned by the gateway may be queried, and if the confirmation character is returned, step 401 may be returned to prepare for the next data transmission.
404. If the confirmation character is not received, inquiring an overtime retransmission mark;
405. if receiving the overtime retransmission mark, judging whether the current retransmission times reach the preset uploading times or not;
it should be noted that, when the confirmation character is not received, the timeout retransmission flag is queried, at this time, reference may be made to steps 401 to 403, when the timeout retransmission flag is received, it is determined whether the current retransmission number reaches the preset upload number, if the preset upload number is reached, the battery switch enters the sleep state, in this application, the maximum upload number may be set to 3, and when the number exceeds three, the upload is stopped.
406. If the retransmission times do not reach the preset uploading times, retransmitting the data to be uploaded to the gateway, and updating the state of the temporary storage queue; and when the retransmission times reach the preset uploading times, stopping sending the current pop-up data, and returning to the step 401.
