ELECTRONIC LOCKING DEVICE HAVING POWER MANAGEMENT FUNCTION AND CONTROL METHOD THEREFOR

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic lock device, and more particularly, to an electronic lock device having a power management function for preventing unnecessary power consumption and increasing power use efficiency, and a control method thereof.

Recently, a highly secure electronic locking device equipped with a fingerprint recognition device and a card recognition device has been provided. Door lock devices for door control are also equipped with a fingerprint recognition device or a card recognition device. Recently, locking devices equipped with high-performance recognition devices, such as a vein recognition device or an iris recognition device, have been provided for the purpose of installation in some high security locations.

The electronic locking device operates by receiving commercial power from the outside or by receiving power from an internal battery. Battery-operated standalone type electronic locking device has the advantage that it can be easily installed without separate wiring work for external power supply.

On the other hand, the stand-alone locking device also includes a high-performance recognition device as described above, so the power consumption is high. However, there is a limit to the additional mounting of the battery in a limited space and to increase the battery charge amount, so that the independent locking device is required to have as low power consumption as possible.

Due to its characteristics, the locking device must always ensure normal operation. For this, a stable supply of operating power is very important. In the case of a standalone lock, frequent battery replacement can seriously compromise the security of the lock. Therefore, the standalone locking device needs to be operated for a long time by the battery once mounted with the lowest power consumption possible.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to prevent unnecessary power consumption of the electronic lock device, and an electronic lock device having a power management function that can minimize the power consumption of the built-in battery and It is to provide a power supply control method for this.

(Example)

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The novel electronic lock device of the present invention supplies power to the lock main circuit when detecting the access of the person, and automatically shuts off the power supply of the fund main device when the control operation is completed to prevent unnecessary battery power consumption. Once installed, the electronic lock can be operated for a long time.

1 is a block diagram showing a circuit configuration of an electronic locking device according to a preferred embodiment of the present invention.

Referring to the drawings, the electronic locking device according to a preferred embodiment of the present invention is a battery 10, power supply / shutdown circuit 20, sensor circuit 30, logic circuit 40, lock device main circuit 50 And an electronic lock mechanism 60.

The power supply / interruption circuit 20 receives the battery power supply Vb from the battery 10 and supplies the first and second operating power supplies V1 and V2 to the sensor circuit 30 and the main circuit 50, respectively. do. Here, the first operating power supply V1 provided to the sensor circuit 30 is a power supply that is always supplied. The second operating power supply V2 is selectively provided as a power supply supplied to the main circuit 50. In the initial state, the power supply / interception circuit 20 provides the first operating power V1 to the sensor circuit 30, and the second operating power V2 is not supplied to the main circuit 50.

The sensor circuit 30 is configured using a passive infrared sensor (PIR) sensor of the passive infrared detection method for detecting a human body and is operated by being supplied with a first operating power V1. In this embodiment, the sensor circuit 30 detects an accessor's access using a PIR sensor, but those skilled in the art know that it is possible to detect an accessor's access using various types of sensors. You will know.

When the human body is detected by the sensor circuit 30, a high level human body detection signal UDS is output and input to the logic circuit 40. As will be described later, the logic circuit 40 outputs a high level power supply / interception signal PSI to the power supply / interception circuit 20 in response thereto. When the human body is detected by the sensor circuit 30, the power supply / interception circuit 20 supplies the second operation power supply V2 to the main circuit 50.

The main circuit 50 is composed of a control unit 52 for controlling the overall operation of the locking device and the person recognition device. The person recognizing apparatus includes, for example, an RF card reader 56 and an RF antenna 58 for reading a password from an RF card (not shown) in which the person's password is embedded. The person recognition device may be configured as one of various types of person recognition devices such as, for example, a fingerprint recognition device, a face recognition device, and a iris recognition device.

The controller 52 may be configured as a microcontroller in which a program for controlling the overall operation of the locking device is embedded. When the second operating power source V2 is supplied, the controller 52 outputs a high level power control signal PCS to the logic circuit 40 after the initialization process is performed. Then, while controlling the RF card reader 56 and electronic lock mechanism 60, the overall operation of the locking device is controlled.

The logic circuit 40 is composed of a logical sum operation circuit. The logic circuit 40 receives a human body detection signal (UDS) and a power control signal (PCS) as inputs and performs a logic operation, and provides the result as a power supply / disconnect signal (PSI) to the power supply / block circuit 20. . That is, when any one of the human body detection signal (UDS) or the power control signal (PCS) is input as a high level signal, a high level power supply / interruption signal (PSI) is output and the second operation power source (V2) is the main circuit. To 50. In other words, when the human body is sensed by the sensor circuit 30, a high level human body detection signal UDS is output to start supplying the second operating power V2. In addition, the output of the second operating power source V2 is continuously maintained by the high level power source control signal PCS output from the controller 52.

The power supply / interception circuit 20 supplies the second operating power supply V2 when the power supply / interruption signal PSI is input at a high level signal, and when the low level signal is input, the second operating power supply ( Block V2). Electronic lock mechanism 60 comprises a mechanical lock assembly and a motor and drive circuit for operating it.

The controller 52 outputs a low level power control signal PCS when the control operation of the locking device is completed. At this time, if the human body detection signal UDS output from the sensor circuit 30 is output at a low level, a logic circuit is output. 40 outputs a low level power supply / interrupt signal PSI. Therefore, the power supply / blocking circuit 20 cuts off the supply of the second operating power supply V2.

Subsequently, a method of controlling the electronic locking device of the present invention will be described in detail with reference to FIG. 2. 2 is a flowchart sequentially illustrating a control method of an electronic locking device according to an exemplary embodiment of the present invention.

Referring to the drawing, when the battery 10 is mounted in the electronic lock device, the first operating power supply V1 is supplied to the sensor circuit 30 in step S10. When the sensor circuit 30 starts to operate and the human body is sensed by the sensor circuit 30 in step S20, the process proceeds to step S30 to supply the second operating power V2 to the main circuit 50. When the second operating power supply V2 is supplied, the controller 52 proceeds with an initialization process.

In operation S40, the controller 52 outputs a power control signal PCS for maintaining the supply of the second operating power V2. In step S50, the controller 52 operates the RF card reader 56 to determine whether there is a password input using an RF card (not shown). If there is no password input, it is determined whether the time specified in step S60 has elapsed. If a normal password input is made within a specified time, the controller 52 controls the electronic lock mechanism 60 to release the lock state in step S70.

If a specified time has elapsed without inputting a password or control of the electronic lock mechanism is completed, in step S80, the controller 52 outputs a power control signal PCS for cutting off the supply of the second operating power supply V2. Thus, the supply of the second operating power supply V2 is cut off.

As such, the electronic locking device of the present invention can be operated for a long time by the battery 10 once installed to prevent unnecessary power consumption by selectively supplying power to the main circuit 50 only when the human body is sensed.

As described above, the configuration and operation of the electronic lock device having the power management function and the control method thereof according to the preferred embodiment of the present invention have been shown in accordance with the above description and the drawings. Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the invention.

According to the present invention as described above, the battery-operated electronic lock device to be supplied to the main circuit of the lock device only when the human body is detected by preventing battery power consumption unnecessary operation for a long time by the battery once installed This becomes possible.
