Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention 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 invention and are not intended to limit the invention.
Fig. 1 shows an embodiment of the WIFI abnormal automatic reconnecting device of the present invention. In an embodiment, the WIFI abnormal automatic reconnection device 1 includes a normal operation module 11 and a low power consumption operation module 12. The normal operation module 11 includes a main power circuit 111, a DSP113, and a memory 112 electrically connected to the DSP113, where the memory 112 stores a mapping table, and the mapping table includes reconnection times and a required interval duration corresponding to the reconnection times. The low power consumption operating module 12 includes a secondary power circuit 121, an MCU122, and a WIFI module 124 electrically connected to the MCU 122. The WIFI module 124 sends the heartbeat data packet to the outside at a first preset time interval. The secondary power circuit 121 supplies power to the MCU122 and the WIFI module 124, and the WIFI module 124 is in a low power consumption mode.
When the MCU122 receives an external wake-up request, the WIFI module 124 is switched from the low power consumption operating mode to the normal operating mode, the MCU122 starts the main power circuit 111, the main power circuit 111 supplies power to the DSP113 and the memory 112, when the DSP113 determines that the WIFI module 124 does not receive a heartbeat feedback signal sent from the outside, the DSP113 obtains the current reconnection number and obtains an actual required interval duration corresponding to the current reconnection number according to the mapping table, and closes the main power circuit 111, and the WIFI module 124 enters the low power consumption operating mode.
After the actual required interval duration, the MCU122 turns on the main power circuit 111, and the WIFI module 124 enters the normal operating mode, and performs reconnection between the WIFI module 124 and the outside. Specifically, the reconnection operation between the WIFI module 124 and the outside includes: the low power consumption operating module 12 further includes a timing module 123 electrically connected to the MCU 122. When the DSP113 determines that the WIFI module 124 does not receive a heartbeat feedback signal sent from the outside, the DSP113 generates a timing reconnection instruction according to an actually required interval duration and sends the timing reconnection instruction to the MCU122, when the MCU122 receives the timing reconnection instruction, the main power circuit 111 is turned off and the timing module 123 is controlled to start timing, when the timing duration of the timing module 123 is consistent with the actually required interval duration, the timing module 123 sends a first start instruction to the MCU122, and after the MCU122 receives the first start instruction, the main power circuit 111 is turned on and the WIFI module 124 is controlled to reestablish communication connection with the outside.
Through this embodiment, when not detecting the WIFI anomaly and in waiting for the actual required interval duration of reconnection after detecting the WIFI anomaly, this automatic reconnection device 1 of WIFI anomaly all is in dormant state, has reduced power consumption. If the WIFI connection is always in an abnormal state, due to the reason that the interval is long in the WIFI reconnection, the WIFI abnormal automatic reconnection device 1 cannot frequently perform the WIFI reconnection operation, and the effect of reducing power consumption is further achieved.
In order to further reduce the power consumption of the WIFI abnormal automatic reconnection device 1 of this embodiment, on the basis of the above embodiment, in other embodiments, the DSP113 further includes a determining unit, where the determining unit is configured to determine whether the communication connection between the WIFI module 124 and the outside is successfully established; if the communication connection between the WIFI module 124 and the outside is not successfully established, adding 1 to the current reconnection number and storing the added value, executing the WIFI abnormality judgment operation again by the DSP113, and judging whether the WIFI module 124 receives a heartbeat feedback signal sent from the outside. If the communication connection between the WIFI module 124 and the outside is successfully established, the WIFI module 124 sends a heartbeat data packet to the outside at a first preset time interval, and receives a heartbeat feedback signal sent by the outside.
It should be noted that the map stored in the memory 112 includes the reconnection times and the required interval durations corresponding to the reconnection times, where the required interval durations corresponding to all the reconnection times are values that increase as the reconnection times increase. For example, the required interval duration corresponding to the first reconnection is 30 seconds, the required interval duration corresponding to the second reconnection is 60 seconds, the required interval duration corresponding to the third reconnection is 120 seconds, the required interval duration is gradually increased according to a certain proportion, the more the number of the WIFI reconnection times, the longer the required interval duration, the more frequent execution of the WIFI reconnection operation is effectively avoided, and the power consumption is reduced.
In order to further reduce the power consumption of the WIFI abnormal automatic reconnection apparatus 1 of this embodiment, when the WIFI abnormal is not detected, the apparatus automatically enters the sleep state from the wake-up state. Therefore, on the basis of the above embodiment, in other embodiments, when the DSP113 determines that the WIFI module 124 receives a heartbeat feedback signal sent from the outside, the DSP113 generates a normal sleep instruction and sends the normal sleep instruction to the MCU122, after the MCU122 receives the normal sleep instruction, the main power circuit 111 is turned off and the timing module 123 is controlled to start timing, when the timing duration of the timing module 123 reaches a second preset duration, the timing module 123 sends a second start instruction to the MCU122, and the MCU122 starts the main power circuit 111. It should be noted that the second preset time length is greater than the required interval time length corresponding to the reconnection times in the mapping table, for example, the second preset time length may be set to 1 day.

The WIFI abnormal automatic reconnection device 1 includes a normal operation module 11 and a low power consumption operation module 12. The normal operation module 11 includes a main power circuit 111, a DSP113, and a memory 112 electrically connected to the DSP113, where the memory 112 stores a mapping table, and the mapping table includes reconnection times and a required interval duration corresponding to the reconnection times. The low power consumption operating module 12 includes a secondary power circuit 121, an MCU122, and a WIFI module 124 electrically connected to the MCU 122. The WIFI module 124 sends the heartbeat data packet to the server 2 at a first preset time interval. The secondary power circuit 121 supplies power to the MCU122 and the WIFI module 124, and the WIFI module 124 is in a low power consumption mode.
When the MCU122 receives an external wake-up request, the WIFI module 124 is switched from the low power consumption operating mode to the normal operating mode, the MCU122 starts the main power circuit 111, the main power circuit 111 supplies power to the DSP113 and the memory 112, when the DSP113 determines that the WIFI module 124 does not receive a heartbeat feedback signal sent by the server 2, the DSP113 obtains the current reconnection number and obtains an actual required interval duration corresponding to the current reconnection number according to the mapping table, and closes the main power circuit 111, and the WIFI module 124 enters the low power consumption operating mode.
After the actual required interval duration, the MCU122 turns on the main power circuit 111, and the WIFI module 124 enters the normal operating mode, and performs the reconnection operation between the WIFI module 124 and the server 2. Specifically, the reconnecting operation of the WIFI module 124 and the server 2 includes: the low power consumption operating module 12 further includes a timing module 123 electrically connected to the MCU 122. When the DSP113 determines that the WIFI module 124 does not receive the heartbeat feedback signal sent by the server 2, the DSP113 generates a timing reconnection instruction according to the actual required interval duration and sends the timing reconnection instruction to the MCU122, when the MCU122 receives the timing reconnection instruction, the main power circuit 111 is turned off and the timing module 123 is controlled to start timing, when the timing duration of the timing module 123 is consistent with the actual required interval duration, the timing module 123 sends a first start instruction to the MCU122, and after the MCU122 receives the first start instruction, the main power circuit 111 is turned on and the WIFI module 124 is controlled to reestablish communication connection with the server 2.
Through this embodiment, when not detecting the WIFI anomaly and in waiting for the actual required interval of reconnecting after detecting the WIFI anomaly, this WIFI anomaly automatic reconnecting device 1 all is in the dormant state, has reduced power consumption, and because of the reason that the interval was long, this WIFI anomaly automatic reconnecting device 1 can't frequent WIFI reconnect the operation, has further reached the effect that reduces power consumption.
In order to further reduce the power consumption of the WIFI abnormal automatic reconnection device 1 of this embodiment, on the basis of the above embodiment, in other embodiments, the DSP113 further includes a determining unit, where the determining unit is configured to determine whether the communication connection between the WIFI module 124 and the server 2 is successfully established; if the communication connection between the WIFI module 124 and the server 2 is not successfully established, adding 1 to the current reconnection number and storing the added value, executing the WIFI abnormality judgment operation again by the DSP113, and judging whether the WIFI module 124 receives the heartbeat feedback signal sent by the server 2. If the communication connection between the WIFI module 124 and the server 2 is successfully established, the WIFI module 124 sends a heartbeat data packet to the server 2 at a first preset time interval, and receives a heartbeat feedback signal sent by the server 2.
Specifically, the mapping table stored in the memory 112 includes the reconnection times and the required interval durations corresponding to the reconnection times, where the required interval durations corresponding to all the reconnection times may be a fixed value or a value that increases as the reconnection times increase. For example, the required interval duration corresponding to all reconnection times may be set to 300 seconds, that is, 300 seconds are required to be required for each execution of the WIFI reconnection operation; the following rules can be set: the required interval duration corresponding to the first reconnection is 30 seconds, the required interval duration corresponding to the second reconnection is 60 seconds, the required interval duration corresponding to the third reconnection is 120 seconds, the required interval duration is increased step by step in a certain proportion, the more the WIFI reconnection times, the longer the required interval duration, the effective avoidance of frequent execution of WIFI reconnection operation is realized, and the power consumption is reduced.
In order to further reduce the power consumption of the WIFI abnormal automatic reconnection apparatus 1 of this embodiment, when the WIFI abnormal is not detected, the apparatus automatically enters the sleep state from the wake-up state. Therefore, on the basis of the above embodiment, in other embodiments, when the DSP113 determines that the WIFI module 124 receives the heartbeat feedback signal sent by the server 2, the DSP113 generates a normal sleep instruction and sends the normal sleep instruction to the MCU122, after the MCU122 receives the normal sleep instruction, the main power circuit 111 is turned off and the timing module 123 is controlled to start timing, when the timing duration of the timing module 123 reaches the second preset duration, the timing module 123 sends a second start instruction to the MCU124, and the MCU124 starts the main power circuit 111. The second preset time length is greater than the required interval time length corresponding to all reconnection times in the mapping table, for example, when the second preset time length is set to be 1 day, the required interval time length is no more than 1 day at most.
Fig. 3 shows an embodiment of the automatic reconnection method for WIFI anomaly according to the present invention. In this embodiment, the automatic reconnection method for the WIFI anomaly is applied to the automatic reconnection system for the WIFI anomaly. The WIFI abnormity automatic reconnection system comprises a server and a WIFI abnormity automatic reconnection device.

Wherein, normal work module include main power supply circuit, DSP and with DSP electric connection's memory, low-power consumption work module includes auxiliary power supply circuit, MCU, WIFI module and timing module. The WIFI abnormity automatic reconnection method comprises the following steps:
step S1, the auxiliary power circuit supplies power to the MCU and the WIFI module, the WIFI module is in a low-power-consumption working mode and sends heartbeat data packets to the server at intervals of a first preset duration, and the WIFI abnormal automatic reconnection device is in a dormant state.
Step S2, when the MCU receives the awakening request, the main power circuit is started, the main power circuit supplies power to the DSP and the memory, the WIFI module is switched from the low-power-consumption working mode to the normal working mode, and the WIFI abnormal automatic reconnection device is switched from the dormant state to the awakening state.
Step S3, the DSP determines whether the WIFI module receives a heartbeat feedback signal sent by the server, if not, executes step S4, and if receives a heartbeat feedback signal sent by the server, executes step S8.
And step S4, the DSP acquires the current reconnection times and obtains the actual required interval duration corresponding to the current reconnection times according to the mapping table, and after the actual required interval duration is separated, the reconnection operation of the WIFI module and the server is executed. Specifically, in other embodiments, the performing the reconnection operation of the WIFI module and the server includes the following steps: step S41, generating a timing reconnection instruction according to the actual required interval duration and sending the timing reconnection instruction to the MCU; step S42, when the MCU receives the timing reconnection instruction, the main power circuit is closed and the timing module is controlled to start timing; step S43, when the timing duration of the timing module is consistent with the actual required interval duration, the timing module sends a first starting instruction to the MCU; step S44, after the MCU receives the first opening instruction, the main power circuit is opened and the WIFI module is controlled to reestablish communication connection with the server.
In order to further reduce the power consumption of the WIFI abnormal automatic reconnecting device, the WIFI abnormal automatic reconnecting method further includes:
step S5, the DSP determines whether the communication connection between the WIFI module and the server is successfully established, if the communication connection between the WIFI module and the server is not successfully established, step S6 is executed, and if the communication connection between the WIFI module and the server is successfully established, step S7 is executed.

Specifically, when the communication connection between the WIFI module and the server is not successfully established, adding 1 to the reconnection number on the basis of the previous reconnection number, and storing the reconnection number. For example, if the reconnection operation is not successful for the first time, the current reconnection number is 0, and adding 1 results in that the current reconnection number is 1. Therefore, the actual required interval duration corresponding to the next reading reconnection time of the DSP being 1 is the actual required interval duration of the next restart operation.
In step S7, the WIFI module sends the heartbeat packet to the server and is in a normal operating state, and then executes step S3.

Specifically, when the DSP judges that the WIFI module receives heartbeat feedback signals sent by the server, namely, when no WIFI is abnormal, the MCU disconnects the main power supply circuit, the WIFI module is converted into a low-power-consumption working mode from a normal working mode, and after the interval of a second preset time, the MCU opens the main power supply circuit and judges whether the WIFI module receives the heartbeat feedback signals sent by the server again. The second preset duration may be a fixed value, but the value of the second preset duration is greater than the actual required interval duration corresponding to the reconnection times in the mapping table.
