Abstract

The present invention relates to a street lamp / security lamp lighting control device using a distributed control method.

In the conventional centralized wireless remote control method, the control lamp of the central system periodically transmits a flashing light control signal, and each of the streetlight / security lamp lighting control devices performs flashing according to the received control signal.

However, in this case, as the load of the radio equipment constituting the central system operating station increases, a failure or an operation error may occur, and thus a serious road traffic or security problem may occur.

In addition, an error of a reference time occurs according to the characteristics and accuracy of a clock circuit, and an error of a lighting time due to such an error also inevitably occurs. However, it is practically impossible to calibrate the reference time of the lighting control device of each streetlight / security lamp individually, because of the time required and manpower.

Therefore, in order to solve this problem, the present invention transmits operation data including the current time instead of periodically outputting the control lamp from the central system operating station, and transmits the current time and points to the clock circuit of the control lamp of the street lamp / security lamp. By using the distributed control method that stores the data necessary to control the lighting of lights such as off lights and security lights, and lights them according to this data, it not only solves the conventional problems but also reduces the load on the central system operating station. In addition, it is possible to turn on at the correct time without time error by calibrating the reference time in the clock circuit of the security light / street light control device periodically, thereby enabling efficient and economical management.

Description

Apparatus for controlling the turn on-turn off of street lamps / security lights using distributed Control}

The present invention relates to a flashlight control device such as a street light / security lamp using a distributed control method. More specifically, it is suitable for distributed control of a plurality of street lamps and security lights using a wireless data communication technology in a system operating station. It relates to a flashlight control device such as a street light / security light using a distributed control system.

In general, there are many kinds of devices for controlling street lights and security lights. For example, there are an illuminance light sensor method, a timer method, and a centralized wireless remote control method.

The illuminance light sensor method uses the light sensor Cds to determine the brightness of the light and turns on when the surroundings of the street lamp / security light are darker than the preset illuminance and turns off when the light is relatively bright. However, since most street lights and security lights are installed around the road, the illuminance light sensor method has a problem in that malfunctions frequently occur because the amount of dust and dust floating in the air due to air pollution is not properly measured.

In addition, the timer method is a method of controlling the point and the light off in accordance with the time indicated by the built-in clock circuit, while preprogrammed and built-in the date and time for each year in the control device. However, even in such a timer method, when a deviation or a problem occurs in the timer control circuit, the date and time must be independently corrected, and since all the tasks must be dependent on manpower, there is a problem of excessive manpower and high cost.

In order to solve such problems, a centralized wireless remote control method has been proposed, and there are largely RF wireless data communication methods and wireless call communication methods.

First of all, the RF wireless data communication method transmits a flashing light control signal to each street light / security light flashing control device from the central system operating station through RF wireless data communication, and to each street light / security light flashing control device from the central system operating station. Receives a control signal of the flashing light transmitted, and controls the lighting of the street lamp, security lights in accordance with the lighting control signal.

However, according to the conventional centralized wireless remote control method, when the central system operating station periodically sends out a control signal to each of the street lamp / security light flashing control device to directly control the street light, security light flashing, As the load on the radio-related equipment constituting the system operation station becomes high, serious problems in road traffic and security may occur due to equipment failures and operational errors.

On the other hand, in order to prepare for errors in the RF wireless data communication, each streetlight / security lamp lighting control device adopts a timer method, and a clock circuit such as a clock IC is installed, but such a clock IC has a large time deviation over time. Therefore, the lighting time according to the preset lighting time table also causes a deviation.

However, it is practically impossible to calibrate the reference time of the clock IC of each streetlight / security lamp control device individually, because of the time required and manpower.

On the other hand, there is also a method of receiving the POCSAG protocol signal transmitted by the calling function provided by the existing wireless call service provider and controls the lighting of the street light / security light according to the command. Like the RF radio method, this method basically includes a timer method in preparation for an error in radio call communication.

However, the wireless paging communication method does not have an additional installation burden of a transmitting device system like the RF paging communication method, but it is cumbersome to periodically call to correct the cost and date and time of paying the fee to the paging service provider. In addition, the continuity of the service is opaque due to the rapid decrease in demand for wireless paging service and the lack of nationwide network configuration. Moreover, it is practically impossible to install a separate system and network for this purpose. .

The present invention was devised to solve the conventional problems, and the distributed control to reduce the load of the radio-related equipment constituting the central system operating station, and to make its own distributed control by each lamp / security lamp control device. The purpose of the present invention is to provide a lighting control device such as a street lamp / security lamp.
