Abstract

An automatic lamp controller is provided to reduce a waste of electric power by turning off various electronic devices after a predetermined time such as late night. An automatic lamp controller includes a microcontroller(50), a memory(45), a reset unit(30), a time setting unit(70), a constant voltage circuit(55), a contact point selector(81), sensor input units(11,12), and output units(20,21,22). The oscillator(40) is coupled with the microcontroller and generates a reference time. The memory stores the reference time and a set time. The reset unit initializes a lamp device, when the lamp device malfunctions. The sensor input units detect a movement of an object. The output units control the lamp device and electric devices. A user inputs the set time by using the time setting unit and stores the set time on the memory.

The present invention detects the presence of a person in the room, such as a classroom, laboratory, office, etc. by the sensor to detect the presence of the room automatically turns on and off the lights for a predetermined time and to maximize the standby power in order to reduce the electrical energy of electrical appliances Efforts have been made to save electrical energy in a way that reduces them, but their use is insufficient due to lack of practicality.

In the prior art, in order to reduce the electric energy of the electric light, there is no conventional technology that can simultaneously control electric appliances such as electric light, air conditioner and fan coil without any electric wiring work.

The present invention has been made to solve the above-described problems, so that it is possible to use all of the various sensors, and also it is possible to embed the sensor in the system, and to separate the system from the use of multiple sensors at the same time, such as classroom, laboratory, office, etc. Detects the presence of a person in a place and judges the presence of a person by an independently programmed microcontroller to turn on the lights while there is a person. The air conditioner and electric appliances that do not have a remote control function are controlled directly through a receiver programmed separately.

The present invention is an " automatic electric control device " capable of controlling all electrical appliances such as lights, air conditioners, fan coils, etc. without going through the prior art of reducing standby power of electrical appliances.

It detects the moving object through the sensor, and the independently programmed microcontroller judges the movement to generate the light ON signal and the remote control output signal, and it is determined by the sensor contact part to select the contact point of the sensor used. FND was adopted for easy setting. In addition, the output unit is adopted as a relay so that it can be easily controlled according to the load of electrical energy. In order to control electric products without remote control function, it is possible to control electric products without electric wiring work by adopting receiver to execute commands according to control signal of remote control using microcontroller programmed independently. All electrical appliances were simply controlled.

The present invention stores and stores the oscillation unit 40, which is its standard time generating unit, and its own time in the microcontroller 50 that controls a lamp, an air conditioner, an electric appliance, etc. by embedding an original program and recognizing a signal detected by a sensor in real time. Memory unit 45, a reset unit 30 for initializing when a program malfunctions, a time setting unit 70 for setting a holding time, a constant voltage circuit unit 55, a contact for selecting a contact point of a sensor (NO / NC ) The selection unit 81, and the sensor input unit (11, 12) for detecting the movement of the object and the output unit (20, 21, 22) for controlling the lights and electrical appliances.

1, 2, and 3 in the operation of the present invention is to input the holding time to turn on the lights, air conditioners, electrical appliances, etc. by detecting the moving object by the time setting unit 70 to the memory unit 45 Store and memorize retention time.

Since the sensor has different contacts according to the manufacturer and the product, the SW of the sensor contact selector 81 for selecting a contact may be selected as NO or NC. However, the NO and NC contacts cannot be used simultaneously.

The main operation of the present invention is to detect the moving object by the sensor to determine the signal input by the sensor input unit 12 in the microcontroller 50 to send a signal to the output unit 20 to turn on the light by the output unit ( 21) generates a remote control ON signal, the remote control generates an ON signal to turn on the air conditioner or give an ON signal to the receiving panel 15, the output unit 24 of the receiving panel to supply power to the electrical appliance. When the object is continuously detected, the ON state is maintained and when there is no moving object, the microcontroller 50 sends an OFF signal after the set time to turn off the light by the output unit 20, and the output unit 22 signals the remote controller OFF signal. The remote controller generates an OFF signal to turn off the air conditioner and gives an OFF signal to the receiver 15 so that the output unit 24 of the receiver cuts off power to the electrical appliance.

The present invention is to unintentionally waste electric energy in the places such as classrooms of public offices, public buildings, etc. used by an unspecified number, such as research rooms, offices, reception rooms, and living rooms of home appliances. It is applied to a place to turn on lights and electric products when there is a person, and to turn off the lights and electric products after a set time when there are no people, to prevent waste of electric energy. It is possible to save electric energy more efficiently than electric energy saving method.
