(application example)
The five-prevention intelligent lock (hereinafter referred to as intelligent lock) for the outdoor equipment of the power distribution network is applied to locking the outdoor equipment of the power distribution network. Each intelligent lock is internally provided with the self-numbering information and a key verification mechanism of the intelligent lock in a main control MCU of a control board 10-1 of an electric control unlocking assembly 10; the key verification mechanism built in the main control MCU is matched with the key authorization mechanism of the management server of the power supply department to the electronic key 100.
When the power supply department outdoor equipment inspection personnel carry out inspection operation, only 1 electronic key 100 needs to be carried; the patrol personnel can acquire the unlocking key and unlocking authorization information on a management server of a power supply department on site by utilizing the USB interface 100-7 of the electronic key 100 before departure, and can also remotely acquire the unlocking key and unlocking authorization information from the management server by wireless communication on the patrol personnel on the patrol unlocking site; the unlocking authority information of the electronic key 100 includes a key number, a number of the to-be-unlocked smart lock, a valid unlocking start time, and valid unlocking end time information.
Referring to fig. 3 and 4, when unlocking is required, a patrol personnel inserts the electronic key 100 into the electronic key hole 4-1 of the intelligent lock cylinder 4, and the electronic key 100 is electrically connected with 2 input electrodes 10-2 of the electric control unlocking component 10 of the intelligent lock through 2 output electrodes 100-4 arranged on the shell plug-in part 100-2 by the patrol personnel via 2 conductive beads 4-4 of the lock cylinder 4; the patrol inspector opens the electronic key through the key switch 100-5 on the electronic key 100, and the electronic control unlocking assembly 10 of the intelligent lock starts working when the electronic key 100 is powered on:
the signal decoupling analysis module on the control board 10-1 of the electronic control unlocking assembly 10 analyzes the unlocking key and the unlocking authorization information from the power supply which is output by the electronic key 100 and is coupled with the unlocking key and the unlocking authorization information and sends the unlocking key and the unlocking authorization information to the main control MCU of the intelligent lock; the master control MCU extracts the lock number of the master control MCU, combines the key number, the effective unlocking starting time and the effective unlocking ending time, adopts the DES encryption algorithm operation in the prior art to obtain a verification key, compares the obtained verification key with the unlocking key sent by the electronic key 100, and judges that the electronic key 100 is unauthorized and refuses to unlock the lockset if the two keys are different or the current time is not between the effective unlocking starting time and the effective unlocking ending time; if the two keys are the same and the current time is between the effective unlocking starting time and the effective unlocking ending time, the main control MCU of the intelligent lock confirms that the electronic key 100 is authorized, at the moment, the main control MCU supplies power to the solenoid 10-3 through the electromagnet driving module, when the solenoid 10-3 is electrified, magnetic force is generated to enable the ejector rod 10-4 made of electromagnet material to extend downwards from the solenoid 10-3 against the elastic force of the reset spring 10-5, and the ejector rod 10-4 pushes the pressing plate 7 downwards into the pressing plate abdicating groove 4-5 of the lock cylinder 4 (as shown in figure 4); at this time, the electronic key 100 drives the lock cylinder 4 to rotate, when the lock cylinder 4 rotates beyond a certain angle (the preferred angle of 3 degrees in the embodiment), the conductive beads 4-4 on the lock cylinder 4 are separated from contact with 2 input electrodes 10-2 of the electronic control unlocking component 10 of the intelligent lock, the electronic control unlocking component 10 is powered off, and the ejector rod 10-4 is reset under the action of the elastic force of the reset spring 10-5; the lock cylinder 4 is continuously rotated to enable the lock tongue 5 which is follow-up with the lock cylinder 4 to be separated from the lock rod 2, the lock rod 2 moves rightwards under the action of the elasticity of the lock rod spring 3, unlocking is achieved, and inspection personnel can overhaul corresponding outdoor equipment of the power distribution network. When the lock is locked after the maintenance is finished, a patrol inspector drives the lock cylinder 4 to rotate in the opposite direction to the unlocking rotation direction through the electronic key 100, the pressing plate 7 is restored to the locking position under the action of the reset elastic force of the second pressing plate spring 9 below the lock cylinder after the lock cylinder rotates in place, and at the moment, the lock rod 2 is pressed down, and the lock rod 2 is clamped with the lock tongue 5 to realize the locking; because the limit protrusion 100-3 on the outer shell of the electronic key 100 is matched with the electronic key limit groove 4-3 of the lock cylinder 4, the lock cylinder 4 must be restored to the initial locking position during locking, and the key can be pulled out, so that the lock cylinder 4 and the pressing plate 7 are ensured to be accurately reset during locking, and unlocking is facilitated next time.
Referring to fig. 5 and 6, the emergency mechanical key 101 is used as an emergency unlocking reserve by a power supply management department, and when an electronic key unlocking fault or an emergency state occurs in a certain intelligent lock, the intelligent lock can be opened by the emergency mechanical key 101:
the emergency mechanical key 101 is inserted into a mechanical key hole 4-2 of the lock cylinder 4, a blade 4-6 in the lock cylinder 4 moves left and right along a notch on the emergency mechanical key 101, the blade 4-6 is meshed with the notch on the emergency mechanical key 101, so that a pressing plate abdication groove 4-5 of the lock cylinder 4 below the pressing plate 7 forms a complete plane, a second pressing plate spring 9 generates downward displacement, the pressing plate 7 is sunk into the pressing plate abdication groove 4-5 under the action of a first pressing plate spring 8, the emergency mechanical key 101 drives the lock cylinder 4 to rotate in the lock body 1, the lock tongue 5 is separated from the lock rod 2, and the lock rod 2 moves rightwards under the action of the elasticity of the lock rod spring 3, so that unlocking is realized. The principle of unlocking the emergency mechanical key 101 is the same as that of unlocking the blade lock by the mechanical key in the prior art, and is not described in detail.
From the foregoing, the intelligent lock provided by the application is adopted by the outdoor equipment of the power distribution network, and has the following technical effects: firstly, under normal conditions, a power supply department patrol personnel only needs to carry one electronic key 100, and the electronic key 100 can be suitable for intelligent locks used by all power distribution network outdoor equipment in the same area by obtaining a key, so that the problems that a large number of keys are inconvenient to carry when the patrol personnel patrol outdoors in the traditional method, and time and labor are wasted when the corresponding keys are required to be found in a large number of keys when unlocking are solved; secondly, by means of the key authorization verification mechanism of the intelligent lock and the electronic key 100, the patrol personnel can only open the intelligent lock on the patrol target within a specified time, and can not unlock the lock by mistake or not within the specified time, so that the problem of misoperation caused by the fact that one key is adopted to open padlocks of all outdoor equipment in the same area in the prior art can be effectively solved.
The above examples and application examples are illustrative of specific embodiments of the present application and not restrictive, and various changes and modifications may be made by those skilled in the relevant art without departing from the spirit and scope of the application, and all such equivalent technical solutions are intended to be included in the scope of the application.
