The present invention relates to an indoor lighting energy saving system, and more particularly to a system for controlling the blinking of the lights automatically according to the change in the number of people by attaching a motion detection sensor to each door.

In general, in large buildings where there are many people, such as classrooms and academies in universities, the lights are always on regardless of whether they are used or day or night.

In addition, even if a power-saving lighting is installed, the conventional indoor lighting automatic lighting device technology has a problem of waste of energy because it consists of all the lights, and because only one infrared sensor is configured to detect the presence of a person, Even if there is no movement, the lights are turned off due to a malfunction that does not exist, and after being turned off, there is an uncomfortable problem of using them again.

On the other hand, in the case of a building equipped with a cooling system in a central control method, the air conditioner is often turned on in the whole of the building in the form of central cooling despite the different number of people in each room has a problem of energy waste.

The present invention was devised to solve the above problems, and an object of the present invention is to provide a system for automatically turning on and off each person by step by attaching a motion detection sensor to each door to accurately grasp changes in indoor personnel. .

In addition, the purpose is to minimize the waste of energy by providing a system that can automatically blink the air conditioner by comparing the room temperature and the reference temperature determined by the temperature sensor.

In order to achieve the above object, the present invention in the energy saving system according to the use of indoor lamps, the sensor unit for detecting the entrance and exit of the person in the infrared, and connected to the sensor unit receives the entrance and exit detection signals transmitted and received And a control unit for controlling the blinking of the entrance light for each predetermined zone, a switch unit connected to the control unit and blinking a light, and a power supply unit for converting AC into DC to supply power to the circuit. .

The sensor unit may include an entrance sensor configured to include a first sensor installed in close proximity to an entrance door and a second sensor installed in line with the first sensor in an entry and exit direction, and a detection sequence of the first sensor and the second sensor. According to the room, characterized in that consisting of the interior lamp energy saving system, characterized in that recognized as leaving.

Hereinafter, with reference to the accompanying drawings will be described a configuration example of the present invention in detail.

1 is a block diagram of an indoor lamp energy saving system according to the present invention, Figure 2 is a schematic arrangement structure of the entrance sensor and the room temperature sensor according to the present invention, Figure 3 is a front door by the light control of the present invention Figure 4 is a structural diagram for explaining the operation of the sensor, Figure 4 is a plan view of the arrangement of the lamp for explaining the step-by-step lighting process of the light according to the present invention.

As shown in Figure 1, the indoor light energy saving system according to the present invention is connected to the sensor unit 10 and the sensor unit 10 for detecting the entrance and exit of the person in the infrared, and receives the entrance and exit detection signals The control unit (Micro Processor) 20 for controlling the flashing of the entrance and the like according to the number of people, the switch unit 30 connected to the control unit 20 to flash the light, and converts the AC into direct current to supply power to the circuit It is composed of a power supply (SMPS: Switching Mode Power Supply) (40).

Here, the sensor unit 10 is installed as the entrance doors as shown in Figure 2 close to the entrance detection sensor (11, 12) for detecting the entrance, and additionally the automatic air conditioning control system according to the room temperature When installed, it is made by further configuring a temperature sensor 13 for detecting the temperature of the room.

The entrance detection sensors 11 and 12 are each composed of two sensors, that is, first sensors 11a and 12a and second sensors 11b and 12b. The first sensors 11a and 12a and the second sensors 11b and 12b are installed in parallel with the entrance direction so as to sequentially detect the entrance and exit, and at this time, the first sensors 11a and 12a are connected to the second sensor ( 11b, 12b) closer to the door than the installation position.

Referring to the operation of the entrance detection sensor of the present invention configured as described above, the second sensor (11b, 12b) after the first sensor (11a, 12a) detects the person as shown in Figure 3 In the case, it recognizes one person as a room and transmits a signal to the control unit.

On the contrary, if the first sensors 11a and 12a detect the person after the second sensors 11b and 12b detect the person, the first sensor 11a and 12b recognizes the person leaving the room and transmits a signal to the controller 20.

In addition, a separate temperature sensor 13 is installed as shown in FIG. 2 to detect the temperature of the room and automatically adjust the air conditioner.

The control unit 20 reads a program, interprets a signal transmitted from the sensor unit 10, grasps the number of people according to whether or not to enter and exits, and gives a command to control a flashing light (CPU: Central Processing Unit) ( 21, a memory 22 for storing a program and data processed by the program, and an input / output port 23 for transmitting a signal input and output from the control unit 20.

The switch unit 30 is composed of a drive 31 for driving a current required for flashing a light and a relay switch 32 for supplying or cutting off electricity.

In this case, when the user enters the room, the sensor unit 10 detects whether the room is entered and transmits the light to the input / output port (I / O port) according to the number of people identified by the central control unit 21 of the control unit 20. 23 is transmitted to the switch unit 30, the drive 31 of the switch unit 30 drives the relay switch 32 to turn on the lights of the area according to the number of people entering.

For example, when one or more than ten people enter the case shown in FIG. 4, the control unit 20 sends a lighting signal to the switch unit 30 so that a light in the area (A) is turned on. When the total occupancy is less than 10 and less than 20, the lights in the areas (A) and (B) are turned on. In the same way, when the number of occupants is 20 or more and less than 30, all the lights in the areas (A), (B), and (C) are lit.

In this manner, as the number of people increases, the lighting stage is increased, and the area of the lights that are turned on increases. As such, the lighting zones for each occupant can be arbitrarily set by the user according to the size and environment of the classroom and stored in the memory 22. You can also

In addition, the power supply device 40 has a structure for converting AC 220V into 12V and 5V DC, where 12V is applied to the switch unit 30, 5V is applied to the control unit 20, respectively.

In the present exemplary embodiment, two sensors are installed in each door, but three or more sensors may be installed as needed to more accurately recognize the access behavior.

On the other hand, in a building installed in a central control method, efficient control is possible by introducing the system of the present invention. The air conditioner control proceeds in a similar order as in the above lighting control, and the embodiment is as follows.

When the temperature sensor 13 detects the room temperature, the controller 20 compares the detected room temperature with a predetermined temperature range stored in the memory 22 of the controller 20. When the room temperature exceeds the reference temperature, the air conditioner is automatically operated by the command of the control unit 20.

On the contrary, when the detected room temperature is lower than the reference range temperature, the control unit 20 automatically stops the air conditioner.

In addition, the reference temperature may be stored in the memory 22 by setting an arbitrary temperature at the user's convenience.

In the energy saving system according to the use of indoor lights and air conditioners as described above, it is possible to install a separate central control unit so as to remotely control several rooms from one place to facilitate convenience.

Effects on the indoor light energy saving system according to the present invention made as described above are as follows.

First, since two sensors are installed in close proximity to one door, it is possible to detect more reliable entrance and exit, and even if the user does not move, it is not turned off before the exiting is detected. Can be.

Second, an entrance sensor is attached to each door to grasp the change in the number of people in the room, thereby controlling the lights to achieve energy savings.

Third, it is possible to automatically control the number of access and the number of people in the building, such as school or academy, so that the management personnel can be optimized.
