Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Fig. 1 is a method flowchart of an embodiment of a single fire switch control method according to the present application, as shown in fig. 1, where fig. 1 includes:
101. receiving downlink data sent by a server through a gateway, and if a single-fire switch is in a dormant state, not receiving the downlink data; after the single fire is started Guan Meige and the sleep state of the first time interval is preset, the receiving state of the second time interval is preset;
it should be noted that, when the server issues data to the single fire switch, the server issues data to the gateway first, the gateway sends the data to the single fire switch again, if the single fire switch is in a dormant state, downlink data cannot be received until the single fire switch is in a receiving state, data can be received, in order to enable the single fire switch to save electric quantity of a battery as much as possible, a preset second time interval can be set every preset first time interval for receiving the data transmitted by the server through the gateway, in the application, the single fire switch is in the dormant state in the preset first time interval, and is in the receiving state in the preset second time interval, wherein the length of the preset first time interval can be set to be greater than that of the preset second time interval, so that the single fire switch can be in the dormant state in most of cases.
102. If the single fire switch is in the receiving state, the single fire switch returns the confirmation character and the report data to the gateway immediately after receiving the downlink data, and enters the dormant state immediately after returning the confirmation character and the report data.
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 dormant state after returning the confirmation character and the report data, so that the single fire switch can reduce the receiving time, thereby reducing the electric quantity consumption of the single fire switch battery, and ensuring the low-power consumption long-duration endurance of the single fire switch. The single fire switch has a receiving state with a certain time after each dormancy time period, so that the single fire switch can ensure the real-time interaction with the server.
According to the method and the device, the dormant state and the receiving state of the single-fire switch are reasonably distributed, so that the single-fire switch can always maintain the shorter receiving state and the longer dormant state, and the single-fire switch can maintain higher instantaneity when guaranteeing low-power consumption long-time endurance, so that the use satisfaction degree of the single-fire switch is guaranteed.
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 sent by a server through a gateway, and if a single-fire switch is in a dormant state, not receiving the downlink data; after the single fire is started Guan Meige and the sleep state of the first time interval is preset, the receiving state of the second time interval is preset;
202. if the single fire switch is in the receiving state, the single fire switch returns the confirmation character and the report data to the gateway immediately after receiving the downlink data, and enters the dormant state immediately after returning the confirmation character and the report data.
203. If the single fire switch cannot receive the downlink data in the preset second time interval where the whole receiving state is located, the gateway continuously transmits 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 a dormant state, the gateway can continuously issue data to the single fire switch (at this time, the single fire switch does not consume power, and rapidly receives the data issued by the gateway after the dormant state is finished), and when the single fire switch enters a 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 single fire switch can immediately return the confirmation character and the report data to the gateway after receiving the downlink data, so that the single fire switch can complete the data receiving and the data feedback in the receiving state, and immediately enter the dormant state after returning the confirmation character and the report data, thereby ensuring the long endurance capacity of the single fire switch battery.
205. If the interval time from the end of the receiving state is smaller 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 a preset fourth time interval;
it should be noted that, in order to ensure that the single fire switch can timely feed back data to ensure the real-time performance of data interaction, the difference between the time point when the single fire switch receives the downlink data and the time point when the receiving state ends can be judged, and the difference is compared with a preset third time interval (the preset third time interval can be set according to the time required by the data reporting), when the difference is smaller than the preset third time interval, the preset second time interval of the current receiving state is prolonged to a preset fourth time interval, for example, from 100ms to 150ms, so that the single fire switch can finish uploading the reported data in the preset fourth time interval.
206. When the single fire switch replies the confirmation character and the reported data in a preset fourth time interval, the single fire switch immediately enters a dormant state after replying the confirmation character and the reported data;
in order to reduce the battery consumption, the single fire switch may immediately enter the sleep state after replying the confirmation character and reporting the data within a preset fourth time interval.
207. If the single fire switch does not reply the confirmation character and report the data in the preset fourth time interval, the single fire switch enters a dormant state immediately after the preset fourth time interval is finished.
It should be noted that, if the single fire switch still does not complete the sending of the report data within the preset fourth time interval, the single fire switch needs to be forced to enter the sleep state at this time so as to ensure the continuous working performance of the single fire switch.
According to the method and the device, the dormant state and the receiving state of the single-fire switch are reasonably distributed, so that the single-fire switch can always maintain the shorter receiving state and the longer dormant state, and the single-fire switch can maintain higher instantaneity when guaranteeing low-power consumption long-time endurance, so that the use satisfaction degree of the single-fire switch is guaranteed.
An interactive timing diagram of another embodiment of a single fire switch control method of the present application is shown in fig. 3.
The foregoing is an embodiment of the server sending data to the single fire switch, and the present application further includes an embodiment of the single fire switch uploading and reporting data to the server, where an interaction timing diagram is shown in fig. 4, and includes: the single fire switch uploads the reported data to the gateway and opens a receiving window with preset time length; after receiving the reported data, the gateway replies the confirmation character and the downlink data to the single fire switch; the single fire switch receives the confirmation character and the downlink data in the receiving window, and enters a dormant state to wait for the next uploading and reporting of the data; if the confirmation character and the downlink data are not received in the receiving window, uploading the reported data again after exceeding the preset time length; after the data is uploaded twice, no matter whether the confirmation character and the downlink data are received, the single fire switch can enter a dormant state.
In a specific embodiment, the application adopts a modified LoRaWAN single fire switch control method, and uses CLASS A and CLASS C modes after LoRaWAN modification to realize the interaction process of a server and a single fire switch, as shown in fig. 5. In this embodiment, the modulation spreading factor sf=7 and the bandwidth bw=500 KHz may be set. In the data reporting stage of the single fire switch, the response time of waiting for the gateway to reply the confirmation character after the single fire switch transmits the uploading data is 30ms; if the single fire switch receives the acknowledgement character replied by the gateway within 30ms after reporting the data, entering a dormant state; if the acknowledgement character is not received within 30ms, the reported data is retransmitted to the gateway after 30ms, and the gateway enters a sleep state after 30 ms. And after the gateway receives the report data of the single fire switch again, packaging the downlink data and the confirmation character and replying.
A stage of transmitting downlink data to the single fire switch at the server: the receiving state time of the single fire switch is 100ms, and a dormant state is arranged between the receiving state and the receiving state. When the server transmits downlink data to the single fire switch through the 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 dormant state after returning the confirmation character, wherein the duration time of the dormant state is 320ms; if the server transmits downlink data 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 in the preset receiving time interval where the whole receiving state is located, the gateway continuously transmits the downlink data to the single fire switch until the single fire switch enters the receiving state again, after receiving the downlink data, the single fire switch returns a confirmation character and reports the data to the gateway, and immediately enters the dormant state after returning the confirmation character.
In a specific embodiment, when the sleep state of the single fire switch is detected to be near the end, the single fire switch is still in a stage of returning the confirmation character and the report data, the receiving state is prolonged by 50ms, and if the confirmation character and the report data are uploaded in 50ms, the single fire switch immediately enters the sleep state after the confirmation character and the report data are uploaded; if the character and the reported data are not completely uploaded within 50ms, the user still waits until the 50ms is finished and then enters a dormant state.
A program flow diagram of one embodiment of the present application is shown in fig. 6, and includes:
the single fire switch inquires whether a key is pressed or whether downlink data issued by the server is received in real time. If the key is detected to be pressed, the key is trembled for 100ms, at the moment, whether the key is pressed is detected again, if the key is still pressed, the key is indicated to be pressed effectively, and otherwise, the key is not effective. Triggering when the key is effective to judge 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 a short time, and canceling the current linkage state if the key is pressed for a long time; and if the data is short pressed, packing the data and uploading the data to a server, and then controlling the terminal equipment in linkage response. If the key is a physical loop key, judging whether the switch is pressed for a long time or a short time, and if the key is pressed for a long time, judging that the current physical loop is canceled to enable the key switch to be switched into a linkage control switch; if the current state of the loop is reported to the server, the data synchronization of the local switch and the server is realized. If the key is a scene key, judging whether the key is pressed for a long time or a short time at the moment, and resetting the whole switch if the key is pressed for a long time; if the short press is detected, the corresponding scene loop data is directly packed and reported to the server, and then the scene control set before is triggered. If the data is detected to be received, the data is analyzed according to a specific protocol, whether the switch is operated or not is determined, and corresponding response data is sent to the server. The remote linkage control and the physical circuit direct local switching are realized, and the remote linkage and the physical circuit switching are also supported according to the corresponding protocol.
In one embodiment of the present application, a program flow diagram combining low power consumption and real-time control is provided; as shown in fig. 7, includes:
when the single fire switch is in a receiving state (wakeup) for 100ms, whether data need to be sent is always inquired, and if not, the single fire switch is in a sleep state (sleep) for 320 ms. If it is found that data need to be transmitted at this time, the type of the data is queried. If the data type is key data, sending acknowledgement data (acknowledgement data), and if acknowledgement character ACK replied by the gateway is received, waiting to enter a dormant state; if not, the single fire switch retransmits the data, and if the retransmitted data reaches twice, the data waits to enter a dormant state. If the data bit responds to the inquiry data controlled by the server, unconfirmed data is sent, and the data bit is not retransmitted after being sent, and directly enters a state of waiting to enter dormancy. In order to ensure that the data can respond to the server in time, the data needs to be replied immediately after the server data is received, and the data can be transferred to the next report unlike key data. So in order to ensure that the data can be normally transmitted without being limited by 100ms wakeup time and 320ms sleep time, a wakeup time of 50ms is needed to be added to the original 100ms wakeup time. Of course, the power supply capability of the single fire switch needs to be considered for increasing 50ms, so once the transmission is completed within 50ms, the sleep state is directly entered, and the complete execution of the whole 50ms is not needed. If the transmission is not completed after 50ms arrives, the forced single-fire switch needs to enter a sleep state at the moment so as to ensure the continuous working performance of the single-fire switch. The diagram shows the whole single fire switch data transmitting process and the realization process of low power consumption and real-time response receiving.
In a specific embodiment, a system framework of the modified lorewan battery switch-based system of the present application is shown in fig. 10, and fig. 10 includes:
STM32G030C8T6, ASR6500SLC driver, button driver, LED driver, UART driver, the transceiver mechanism that corrects the CLASS A mode in LoRaWAN and the transceiver mechanism that corrects the CLASS C mode combine together, adopt SEMTECH company LLCC68 (thing networking wireless communication spread spectrum module) or ASR6500SLC (LoRa wireless communication radio frequency chip), the performance is better than SX1278, the transmission distance is farther, the transmission power consumption and the receiving power consumption are lower, make battery switch product life-span longer.
