The pyroelectric infrared sensor (PIR) can convert the infrared signal change with the wavelength of 8-12 um into an electric signal and can inhibit the white light signal in the nature. Therefore, when no moving object (such as a human body) moves in the acquisition area of the pyroelectric infrared sensor, only the background temperature is sensed by the pyroelectric infrared sensor, and when the moving object (such as the human body) exists in the acquisition area, a difference signal between the temperature of the moving object (such as the human body) and the background temperature is sensed by the pyroelectric infrared sensor through the Fresnel lens and is sent to the processing unit.
It should be noted that the motion parameter may be a thermal radiation parameter and/or an angle parameter of the moving object, and the thermal radiation parameter may be an electrical signal parameter formed by a difference signal between the temperature of the moving object (e.g., a human body) and the background temperature. The angle parameter may be an angle between a straight line connecting a highest point and a lowest point of a difference between the temperature of the moving object (e.g., a human body) and the background temperature and an angle between a triangle formed by using the thermal radiation collection unit as a vertex in a direction perpendicular to the ground when the thermal radiation collection unit collects the temperature of the moving object (e.g., a human body).
It should also be noted that the smart lock may include a dormant state and an unlocked state during use.
And the distance measuring unit is used for acquiring distance parameters between the intelligent lock and the mobile object according to the acquisition instruction of the processing unit.
Specifically, the distance measuring unit may be an infrared distance measuring unit, and the distance parameter may be a distance between the smart lock and the moving object.
It should be noted that, in this application, through whether have the moving object in the heat radiation collection unit judgement collection region, obtain the distance between intelligent lock and the moving object through the range finding unit, can judge effectively whether the moving object that gets into in the collection region will unblank to reduce the mistake of intelligent lock and start, improve the rate of accuracy that the intelligent lock got into the state of unblanking.
Still need explain, when the intelligence lock is in the dormant state, only thermal radiation collection unit is in operating condition all the time, and when the motion parameter that thermal radiation collection unit gathered satisfied first preset condition, the range unit just begins work. Through the working mode of setting up above-mentioned functional module, can reach the purpose of practicing thrift the electric energy to can the effectual life who prolongs intelligent lock.
And the processing unit is connected with the thermal radiation acquisition unit and the distance measurement unit and used for controlling the intelligent lock to enter an unlocking state according to the thermal radiation parameters and the distance parameters of the moving object.

It should be noted that, because the mobile object can be the human body also can be other removal animals, when thermal radiation parameter more than or equal to the second threshold value, increase the condition whether be in first predetermined angle scope of angle parameter, can effectual filtration because some other animals are close to the intelligence lock, the intelligence lock mistake that causes starts. The accuracy when can effectual improvement intelligence lock starts practices thrift the electric energy and prolongs the life of intelligence lock.
Optionally, the thermal radiation collecting unit is a pyroelectric sensor unit, and is composed of a pyroelectric infrared sensor and a fresnel lens.
Optionally, the distance measuring unit is an infrared distance measuring unit.
Specifically, when the intelligence lock is in the dormant state, only thermal radiation collection unit is in operating condition all the time, and when the motion parameter that thermal radiation collection unit gathered satisfied first preset condition, processing unit wanted the range unit to send the activation instruction, and control the range unit and begin work.
Specifically, the distance parameter may be a distance between the smart lock and the mobile object, and the distance measurement unit sends a measurement result, which may be the distance parameter, to the processing unit, and the processing unit receives the distance parameter.
Optionally, the unlocking instruction is face recognition information or iris recognition information.
Optionally, the main control chip of the door lock control unit is full log a 20.
