In wisdom lighting system, centralized control ware and loop controller need have the correct clock just can ensure correct street lamp switch, otherwise can appear the unusual switch condition of street lamp, turn on the light in daytime or turn off the light condition at night promptly. However, in actual operation, abnormal lamp switching often occurs, and the main reason is caused by the clock error problem of the centralized controller or the loop controller. Therefore, in order to solve the clock error problem, embodiments of the present invention provide a clock support method for an intelligent lighting system, which is described in the following.
Step S101, obtaining an initial clock of the platform of the Internet of things and initializing a clock of the integrated street lamp controller and a clock of the loop controller according to the initial clock.
In an embodiment, after the street lamp is built, the centralized controller in the street lamp can acquire an initial clock from the platform of the internet of things, and then the clock initializes the clock of the centralized controller and the clock of the loop controller.
Step S102, detecting whether a first heartbeat packet sent by the Internet of things platform is received or not when the street lamp runs; wherein the first heartbeat packet includes first clock update data.
In an embodiment, the clock of the centralized controller is initialized and then the heartbeat packet sent by the platform of the internet of things can be detected, and the heartbeat packet contains clock data of the platform of the internet of things. Illustratively, the heartbeat packet of the internet of things platform can be sent once in 1-2 minutes, and in this embodiment, once in 2 minutes is recommended.
Step S103, if a first heartbeat packet sent by the Internet of things platform is received when the street lamp runs, whether a first error between the clock updating data and a current clock of the centralized controller is larger than a first threshold value or not is analyzed; and if the first error is larger than a first threshold value, correcting the clock of the centralized controller according to the clock updating data.
In an embodiment, if the centralized controller receives a heartbeat packet sent by the internet of things platform when the street lamp operates, whether a first error between clock update data in the heartbeat packet and a current clock of the centralized controller is greater than a first threshold value or not is further analyzed, and if the first error is greater than the first threshold value, the clock of the centralized controller is corrected according to the clock update data.
For example, the value of the first threshold may be set to 1 minute. When the first error between the clock updating data in the heartbeat packet and the current clock of the centralized controller is more than 1 minute, the centralized controller corrects the clock of the centralized controller according to the clock updating data.
In an embodiment, after the clock initialization of the loop controller is completed, the loop controller may also detect whether a second heartbeat packet sent by the centralized controller is received; wherein the second heartbeat packet includes second clock update data; and if the loop controller receives the second heartbeat packet, updating the clock of the loop controller according to the second clock updating data. And if the loop controller does not receive the second heartbeat packet, the loop controller is reconnected with the centralized controller, and the clock of the loop controller is updated according to the acquired clock data.
Illustratively, the second heartbeat packet may be sent once in 5-10 minutes, with the present invention implementation choice set to be sent once in 10 minutes.
Further, the method further comprises: whether the loop controller is successfully connected with the integrated controller within a preset time period is analyzed; and if the loop controller is not successfully connected with the integrated controller within the preset time period, resetting the loop controller.
In the implementation process, if the loop controller is not successfully connected with the centralized controller within a preset time period, the loop controller resets to enable the clock of the loop controller to be recovered to the initial state.
104, if the first heartbeat packet sent by the internet of things platform is not received when the street lamp runs, analyzing whether a second error between the current clock and a clock updated by the centralized controller last time is greater than a second threshold value; and if the second error is larger than a second threshold value, restarting the street lamp and resetting the clock of the centralized controller and the clock of the loop controller according to the clock of the Internet of things platform.
In one embodiment, if the centralized controller does not receive the heartbeat packet sent by the internet of things platform when the street lamp operates, whether a second error between the current clock and a clock updated by the centralized controller last time is greater than a second threshold value is further analyzed; if the second error is larger than a second threshold value, restarting the street lamp by the centralized controller; and then clock data are acquired from the platform of the Internet of things again, and the clock of the centralized controller and the clock of the loop controller are reset according to the clock data.
For example, the value of the second threshold may be set to 1 hour. And if the second error between the current clock and the clock updated by the centralized controller last time is more than 1 hour, restarting the street lamp by the centralized controller, then acquiring clock data from the Internet of things platform again, and resetting the clock of the centralized controller and the clock of the loop controller according to the clock data.
In one embodiment, after the clock initialization of the loop controller is completed, whether a second heartbeat packet sent by the centralized controller is received is detected; wherein the second heartbeat packet includes second clock update data; and if the loop controller receives the second heartbeat packet, updating the clock of the loop controller according to the second clock updating data.
In one embodiment, the method further comprises: after the clock initialization of the loop controller is completed, timing is carried out through a set clock chip; and simultaneously, the loop controller updates the clock according to the clock data of the clock chip.

If the loop controller is not connected with the centralized controller, the street lamp can be controlled to normally execute the illumination task according to the clock data in the clock chip; the normal work of street lamp also can be guaranteed under the condition that the centralized controller is off-line for a long time.

For example, the value of the first threshold may be set to 1 minute. When the first error between the clock update data in the heartbeat packet and the current clock of the centralized controller 210 is greater than 1 minute, the centralized controller 210 corrects its own clock according to the clock update data.
The centralized controller 210 is further configured to, if a first heartbeat packet sent by the internet of things platform 100 is not received, analyze whether a second error between the current clock and a clock updated by the centralized controller 210 last time is greater than a second threshold; if the second error is greater than the second threshold, the street lamp 200 is restarted, and the clock of the centralized controller 210 and the clock of the loop controller 220 are reset according to the clock of the internet of things platform 100.
For example, the value of the second threshold may be set to 1 hour. If the second error between the current clock and the clock updated by the centralized controller 210 last time is greater than 1 hour, the centralized controller 210 restarts the street lamp 200, and then acquires the clock data from the internet of things platform 100 again, and resets the clock of the centralized controller 210 and the clock of the loop controller 220 according to the clock data.
