Problems solved by technology

[0003] However, the traditional control method does not have the ability to detect the angle of the rotation direction, so the angle control cannot be realized, and the work of the motor can only be controlled by the locked-rotor current. This method has obvious problems:
In order to prevent misjudgment due to stalling in the process of unlocking and locking, the output power of the motor is required to be large enough. The direct problem brought about by this is that the design margin is too large, and the power supply must be able to provide 10 times the normal operating current. output capacity; the second is that when the windproof bolt returns to its position, it can only be controlled by time. When interference affects the timing accuracy or the motor load changes affect the motor speed, there will be problems of insufficient rotation or overtime rotation, which will affect the normal opening and closing of the door. Hidden dangers in use; the third is that the large current and impact force when the motor is blocked will cause great damage to the components on the control circuit board, the lock body, and the lock cylinder, which will easily cause electromechanical failures and seriously affect the reliability and service life of the product.

Embodiment 1

[0060] refer to figure 1 , the first embodiment of the present invention provides a smart lock control method, including:

[0061] Step S100, receiving a wake-up and power-on command, waking up the DC servo motor according to the wake-up and power-on command and powering on to start;

[0062] As mentioned above, it should be noted that a DC servo motor (servo motor) refers to an engine that controls the operation of mechanical components in a servo system, and is an auxiliary motor indirect transmission device. The DC servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the DC servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. The signal is converted into angular disp...

Embodiment 2

[0072] refer to figure 2 , the second embodiment of the present invention provides a smart lock control method, based on the above figure 1 Shown embodiment 1, wherein said initialization procedure comprises:

[0073] Step S310, obtaining the maximum operating current and the average operating current of the DC servo motor rotating clockwise from the starting point; and judging whether the output shaft of the DC servo motor and the lock cylinder are concentric according to the maximum operating current and the average operating current;

[0074] As mentioned above, the assembly state includes normal concentricity and abnormal concentricity. In this embodiment, it means whether the output shaft of the motor and the rotating shaft of the lock cylinder are concentric when the lock is assembled. Larger, power consumption becomes larger. In this embodiment, by first judging whether the output shaft and the rotating shaft are concentric, the assembly of the lock itself is detect...

Embodiment 3

[0086] refer to image 3 , the third embodiment of the present invention provides a smart lock control method, based on the above figure 2 In the second embodiment shown, in the step S340, "according to the first positioning pulse number, the first counting pulse, the second positioning pulse number and the second counting pulse, determine the The unlocking method corresponding to the rotation direction angle of the motor" includes:

[0087] Step S341, judging whether the second number of positioning pulses is greater than the first number of positioning pulses;

[0088] As mentioned above, in this embodiment, what is involved are the steps of the initialization program. Before step S41, it may also include:

[0089] Determine whether there is a stall current; if so, enter the fault processing module to execute the fault processing program; if not, complete the door opening or closing command, send execution status information to the host computer through the communication...

Abstract

The invention provides an intelligent lock and control method thereof. The method includes: receiving an awakening and energization instruction to perform energization and starting; receiving a factory setting restore instruction; executing an initialization program according to the factory setting restore instruction, and determining an unlocking manner corresponding to the rotation direction andangle of a direct-current servo motor; receiving an unlocking instruction, executing a drive program according to the unlocking instruction, and controlling the intelligent lock to unlock according to the unlocking manner. The method has the advantages that the direction and angle control manner is used to replace a traditional locked-rotor current control manner, excessively large output currents in system operation and mechanical structure damage caused by frequent locked-rotor impact are avoided, energy consumption is lowered greatly, potential safety hazards caused by the traditional locked-rotor control method are avoided, the reliability of the intelligent lock is increased, and the service life of the intelligent lock is prolonged.

Description

technical field [0001] The invention relates to the technical field of intelligent lock design, and more specifically, relates to an intelligent lock control method and an intelligent lock. Background technique [0002] The driving part of the existing fully automatic electronic lock is a DC motor, which mainly has two structural forms: one is that the motor drive mechanism is located in the lock body of the electronic lock; the other is that the motor drive mechanism is located in the panel of the electronic lock . For the application where the motor drive mechanism is located in the lock body of the electronic lock, its control method can reasonably set a certain number of position detection switches in accordance with the structure of the lock body, and the closed-loop control of the motor is formed by detecting the different position states of the door and the deadbolt. The structure of the automatic lock body is relatively complicated, and the processing requirements a...
