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. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the application provides an automatic binding method and system for an intelligent lamp pole and an access device ID, and the method and system can solve the problems that the intelligent lamp pole is slow in deployment and high in labor intensity in the related technology.
As shown in fig. 1, the method for automatically binding an intelligent lamp pole and an access device ID in the embodiment of the present application includes the steps of:
s1, after receiving the self ID sent by the street lamp controller, the street lamp pole management subsystem generates a lamp pole object of the intelligent lamp pole facility for the street lamp controller which does not generate the lamp pole object according to the ID of the street lamp controller.
The lamp post object ID is the ID of the corresponding street lamp controller.
And S2, the access adapter forwards a communication data packet containing the ID of the access adapter to the lamp post management subsystem, calculates a hash value of a payload part of the communication data packet, and reports the hash value to the lamp post management subsystem through the corresponding street lamp controller.
And S3, the lamp post management subsystem calculates the hash value of the payload part of the received communication data packet and binds the lamp post object ID with the same hash value with the access equipment ID.
In the cache of the lamp pole management subsystem, the ID of the lamp pole object and the hash value forwarded by the street lamp controller on the lamp pole are bound and stored, and the ID of the access device and the hash value of the payload part of the communication data packet of the access device calculated by the lamp pole management subsystem are bound and stored.
According to the automatic binding method of the intelligent lamp pole and the access equipment ID, the street lamp controller can send the ID of the street lamp controller and the hash value calculated by the access adapter to the lamp pole management subsystem, the access adapter can also forward communication data sent by the access equipment to the lamp pole management subsystem, and when the lamp pole management subsystem calculates the hash value of the payload part of a received communication data packet and receives the hash value forwarded by the street lamp controller, the calculated hash value can be matched with the hash value sent by the street lamp controller, and the lamp pole object ID with the same hash value is bound with the access equipment ID.
On the basis of the foregoing embodiment, in this embodiment, after the lamp post management subsystem receives the communication data packet, the method further includes:
and the lamp post management subsystem analyzes and acquires the ID of the access equipment from the received communication data packet according to the equipment protocol, judges whether the ID of the access equipment is bound with the ID of the lamp post object, and calculates the hash value of the payload part of the communication data packet if the ID of the access equipment is not bound with the ID of the lamp post object.
Further, after the light pole management subsystem calculates the hash value of the payload portion of the received communication data packet, the method further includes:
firstly, the lamp post management subsystem judges whether a hash value which is the same as the calculated hash value and a lamp post object ID corresponding to the same hash value are stored in a cache. If so, binding the ID of the access equipment with the ID of the lamp post object, clearing the stored hash value and the corresponding ID of the lamp post object, and stopping the access adapter accessed by the ID of the access equipment from calculating the hash value of the communication data packet of the access equipment.
Otherwise, the lamp pole management subsystem binds the ID of the access equipment and the hash value obtained by calculation and caches the ID.
Specifically, after calculating the hash value of the payload portion of the received communication data packet, the lamp post management subsystem needs to first determine whether the hash value reported by a certain street lamp controller in the cache is the same as the hash value, and if so, can find the street lamp controller ID corresponding to the same hash value, and further determine the corresponding lamp post object ID, so as to bind the new access device ID with the found lamp post object ID.
In this embodiment, after the lamp pole management subsystem binds and caches the ID of the access device and the hash value obtained by calculation, the method further includes:
first, a first timeout time is set, and the cache time of the binding data is timed. And deleting the binding data when the caching time of the binding data exceeds a first timeout time. The binding data is the hash value which is obtained by calculating the ID of the access equipment and the lamp pole management subsystem and corresponds to the access equipment.
In this embodiment, the first timeout period is set to prevent the communication data between the street lamp controller and the lamp post management subsystem from being lost, so that the current cached ID of the access device and the calculated hash value may not have a chance to be matched again, and the current cached ID and the calculated hash value occupy the cache resource all the time.
On the basis of the foregoing embodiment, in this embodiment, after the lamp post management subsystem receives the hash value reported by the street lamp controller, the method further includes:
firstly, the lamp pole management subsystem judges whether a hash value identical to the received hash value and an access device ID corresponding to the same hash value are stored in a cache. If yes, binding the corresponding lamp post object ID with the access equipment ID, clearing the stored hash value and the corresponding access equipment ID, and stopping the access adapter accessed by the access equipment ID from calculating the hash value of the communication data packet of the access equipment.
Otherwise, the lamp post management subsystem binds and caches the ID of the lamp post object and the hash value reported by the street lamp controller.
Specifically, after the lamp post management subsystem receives the hash value reported by the street lamp controller, it needs to first determine whether the hash value of the payload portion of the communication data packet of a certain access device is the same as the hash value in the cache, and if so, the access device ID corresponding to the same hash value can be found, so as to bind the lamp post object ID corresponding to the street lamp controller with the found access device ID.
Further, after the lamp post management subsystem binds and caches the lamp post object ID and the hash value reported by the street lamp controller, the method further comprises the following steps:
first, setting a second timeout, and timing the cache time of the binding data. And when the caching time of the binding data exceeds a second overtime time, deleting the binding data. The binding data is the lamp post object ID and the hash value sent by the corresponding street lamp controller and received by the lamp post management subsystem.
In this embodiment, the second timeout period is set to prevent the loss of the communication data packet between the access device itself and the lamp post management subsystem, which may cause the hash value reported by the currently cached street lamp controller and the corresponding lamp post object ID to have no chance to be matched again, and thus the cache resource is always occupied.
Alternatively, the timeout time may be determined according to the average network communication delay time, which is generally a multiple of the average network communication delay time. In this embodiment, the first timeout time and the second timeout time are 3 times of the average network communication delay time.
