Description

{System and method for indoor enter count}

The present invention relates to a dual motion sensor utilization indoor access counting system and method.

The present invention targets the field of industrial security and energy management systems. Industrial security is a newly emerging convergence security such as information security, physical security, and manpower management. According to the information security trends of domestic and foreign countries announced by the Korea Internet Development Agency in 2012, the domestic convergence security market exceeded 1.30 trillion won in the information security market in 2010 and continuously grows at an annual average rate of 32% And the present invention will be utilized as a basic technology necessary for establishing a security environment.

According to the data released by the Ministry of Commerce, Industry and Energy in 2014, the market size of the domestic energy management system is expected to reach KRW 295 billion by 2013, which will grow at a CAGR of 34.7%

The convergence security market in Korea is expected to reach about 1.78 trillion won in 2010, with an annual average growth rate of 32% until 2018, which is expected to reach 12.8 trillion won. The present invention is utilized as a basic technology for establishing a security environment Will be.

There is already a technology to count the number of passengers with motion sensor. There are many ways to determine the number of people who are in the room such as touching the NFC card manually and detecting the movement of the NFC card by using the motion sensor, but the method using the motion sensor is widely used. This is because the user has no additional device or action to take and the price is cheap.

However, the method of using the motion sensor has a somewhat lower accuracy than the other methods. This is because the user may misunderstand whether the user is entering the room or outdoors.

An object of the present invention is to provide a system and method for indoor access counting using a dual motion sensor in which a motion sensor is installed on a wall and a ceiling in a doorway and a doorway to count the number of people entering and departing more accurately than when one is installed.

In accordance with one aspect of the present invention, a dual motion sensor utilizing indoor access counting system is disclosed.

The indoor / outdoor counting system according to an embodiment of the present invention includes a sensor unit for sensing motion from a motion sensor, a storage unit for storing a sensing result, an operation unit for performing count determination based on a result received from the motion sensor, And the like.

Utilizing the proposed dual motion sensor indoor access count in the field of industrial security and energy management system, it is possible to provide various user-oriented services, and installation is relatively simple and cost-effective.

FIG. 1 is a flowchart of a process of counting indoor access using a dual motion sensor proposed in the present invention. FIG.
2 is a block diagram of the configuration of a technique proposed by the present invention;

As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. In this specification, the terms "comprising ", or" comprising "and the like should not be construed as necessarily including the various elements or steps described in the specification, Or may be further comprised of additional components or steps. Also, the terms "part," " module, "and the like described in the specification mean units for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software .

In an industrial security or energy management system, it is possible to create a variety of services by knowing the number of occupants in a specific space in part. It usually uses one motion sensor, which is somewhat less accurate. However, the present invention uses a dual motion sensor to improve accuracy.

Install the motion sensor in the door frame the same as the existing access counting technology using the motion sensor. Then install an additional motion sensor on the ceiling somewhat away from the door. The second motion sensor may be used in place of the motion sensor used in the front door. In such a dual-mounted motion sensor, the recognition time difference is obtained to distinguish whether the current passing user is entering the room or exiting. With this method, it is possible to count more precisely than existing methods using only one motion sensor.

The present invention has a process flow as in Fig. In addition to the motion sensor (No. 1 sensor) installed in the door frame as in the prior art, motion is detected in the motion sensor (# 2 motion sensor) installed in the ceiling (S100). If it is detected by the first motion sensor (S101), the process waits until motion of the first motion sensor is not detected (S102). Thereafter, if motion is detected in the second motion sensor (S103), the number of people in the room is counted by +1 person (S104), and the process ends. Otherwise, the process ends immediately.

 If the motion is detected in one of the two motion sensors but not in the first motion sensor (S101), the process waits until the second motion sensor detects motion (S105). Thereafter, if motion is detected by the first motion sensor (S106), the number of people in the room is counted by one (S107), and the process ends. If not, the process ends immediately.

 2, a server unit 200, a sensor unit 201, a storage unit 202, a network unit 203, and an operation unit 204 are provided. The arithmetic unit 204 determines the count based on the result received from the motion sensor. The arithmetic unit 204 determines whether the motion is detected from the motion unit 203, Transmits these results to the outside.

The number of indoor passengers counted by simple motion sensors can be applied to various fields such as industrial security and energy management system.
