Abstract

A method of automatically lighting lamps is provided to light the lamps during a predetermined time in detecting a moving object by using heat detecting sensors and infrared sensors. Heat detection/infrared sensors(11,21,31) detect a motion of a moving object in a wide area. If the moving object is detected, plural lamps are turned on by relay output units(13,23,33) during a predetermined time. If the moving object is not detected, the predetermined time is inversely counted. If the moving object is detected during the inverse counting, the lamps are turned on during the predetermined time.

The present invention is a combination of an infrared sensor and a heat sensor for a light used in a large area such as an underground parking lot in an apartment building or a public building, and automatically detects a moving object such as a person or a vehicle in a detection area in real time and automatically lights a lamp such as a fluorescent lamp for a set time. The present invention relates to an automatic light control method that lights up and turns off.

In the prior art, it was possible to use a sensor lamp or to control only one fluorescent lamp to save the power of the lamp.In addition, the lamp was turned off for a few seconds to be turned on again after the sensor was detected. It was not possible to use it in such a large place, and it was also possible to use a highly efficient power device, a method of improving power factor, or a method of constructing a mutual induction reactor "Patent No. 141448" and a mutual induction reactor type power saving device "Patent No. 127090". The power saving effect is very low.

In addition, the thermal sensor is a red LED is used to know whether the sensor is operating or not used for security purposes are not used separately.

In addition, in the conventional technology, by incorporating a high-brightness LED in the thermal sensor as in the present invention, the lamp is invented so as to illuminate a minimum amount of light even when the light is turned off so that the “emergency exit” indicator can be substituted to solve the inconvenience, and the movement is sensed. When the setting value is maintained, the lamp is controlled, and all the lights are designed to be turned on immediately after the sensor is detected, except that the lamp is turned on several tens of seconds after the supply of mercury lamp.

In particular, many lights are used in large places such as underground parking lots of apartments, buildings, and public parking lots that are used by unspecified people at unspecified times. It caused user inconvenience and had to turn on for 24 hours.

As a result, a lot of electric energy is wasted unnecessarily, and there was no device to control a group of lights for saving electric energy in such an underground parking lot.

The present invention has been made to solve the above problems, by using a combination of a heat sensor and an infrared sensor to detect the presence of a person in the underground parking lot so that the lights are turned on while a person or a moving vehicle is present, If no movement is detected, the counter is counted at the preset time and turned off after a certain time.If no movement of a person, etc. is detected, the counter is counted at the preset time. It aims to automatically control the lights by providing a minimum of light to solve the embarrassment of people who will remain in a lighted underground parking lot and easily inducing the movement to the place where the sensor is located so that the sensor can be detected to turn on the lights. .

After detecting the presence of a person, the light is turned on and off, and then the presence of a person must detect the presence of a person again. The microcontroller adopts a unique program using a heat sensor and an infrared sensor in a place to provide an automatic light control method that detects a moving object such as a person or a vehicle and turns the light on and off.

The thermal sensor and infrared sensor detect moving objects and give the microcontroller a signal of sensor contact NORMAL CLOSE (NC) or NORMAL OPEN (NO), and these sensors are properly placed in the parking lot for people or vehicles. It detects moving objects, such as a large parking lot, and sets up three different zones to operate differently to increase the energy savings, and adopts FND to easily set the maintenance time of the lights. It can be set up to 999 seconds, and it is possible to control the lights of the underground parking lot regardless of the number of lights by configuring the output part as a relay contact so that it can be easily controlled according to the electric energy load.

According to an embodiment of the present invention, a microcontroller 50 having a built-in original program and recognizing a detected signal to control a lamp such as a fluorescent lamp, an oscillator 51 which is its own standard time generator, and a memory unit for storing and storing a retention time 40, a reset unit 52 for initializing when a program malfunctions, a time setting unit 70 for setting a holding time, an automatic / manual selection unit 80 for selecting automatic and manual operation, and a constant voltage Circuit unit 53, input sensor contacts (NO, NC) selector 90, sensors and inputs (11, 12, 21, 22, 31, 32) and tanks for detecting moving objects such as people or vehicles Relay outputs 13, 23, 33 to control the lights of the.

In the operation of the present invention in FIG. 1 and FIG. 2, when the holding time to turn on the light of the tank is detected by the time setting unit 70 when the moving object such as a person or a vehicle is detected, the memory unit 40 is provided. Save and remember the retention time.

In addition, if you need to stay for a long time in the underground parking lot, if you switch to use the automatic / manual selection unit 80 manually, the light is kept on, and when the operation is finished, switch the automatic / manual selection unit 80 You can select it automatically.

Since the thermal sensor and the infrared sensors 11, 21, and 31 have different contacts according to the manufacturing company, the sensor contact selector 90 may be selected as NO or NC. However, NO and NC contacts cannot be used together without manipulation.

The main operation of the present invention operates when the thermal sensor and the infrared sensor 11, 21, 31 detect a moving object such as a person or a vehicle, and incorporates a unique program by the sensor input units 12, 22, 32. Send a signal to a microcontroller 50 to operate the relay output unit (13, 23, 33) to turn on the light.

The microcontroller 50 incorporating its own program continuously checks the operation of the thermal sensor and the infrared sensors 11, 21, and 31 even after the lamp is turned on, and signals the sensor inputs 12, 22, and 32. If there is no reverse counter at the existing set time, if the motion is detected at the sensor input unit 12, 22, 32 even during the counter counter, the microcontroller 50 maintains the set time again and the time appears in the time setting unit 70. To do that. If there is no signal in the sensor input units 12, 22, and 32 again, the counter is countered at the set time, and is turned off by the relay output units 13, 23, and 33 after the set time.

In FIG. 3, the operation of the present invention is shown as an algorithm, which is started by supplying power to the automatic power saving control device and initializes the delay time set by the time setting unit 70 and the memory unit 40 of FIG. 1. It detects a moving object such as a person or a vehicle, turns on a light when there is a moving object, and counts back from the set time when there is no moving object. Even during the counter counter, the movement of the object is continuously checked, and when a moving object is detected, the lamp returns to the set time and keeps the light on. After repeating this operation, since there is no moving object, the lamp is turned off after the counter for the set time to maintain the initial state.

The present invention is applied to the place where the lights of the underground parking lot, such as apartments, government offices, public buildings, etc. used by unspecified majority consumes a large amount of electric energy unnecessarily, rather than reducing electric energy by the existing power factor correction or improvement method. In order to reduce the electric energy, and improve the habit of using the underground parking lot, more electric energy can be saved.

In addition, the underground parking lot is operated darkly by keeping the luminaire, which does not obey the legal illuminance of 70Lux. The present invention brightly manages the underground parking lot to solve this problem and excellent crime prevention and crime prevention effect.
