Description

A streetlight remote watching system

The present invention relates to a street light remote control system, and more specifically, to detect the commercial power input to the street lamp in the power failure monitoring unit to check whether the power failure, and when the power failure is confirmed, at the same time replacing the commercial power with the power of the charging unit It transmits the data indicating the identification code and the power failure status, and measures the current of the line to monitor the line condition, and then sends the identification code of the street light and the measurement data of the current so that the state of the street light can be known in real time.

In general, a conventional street light control method includes a control method of turning on and off a power switch of a street light, and a control method using an optical sensor that turns on and off a street light by measuring the brightness of light; There is a control method using a time switch to turn on and off by time by inputting the sunrise and sunset times.

However, the conventional street lamp control method only controls the lighting and turning off, and when the street lamp itself does not operate due to a power failure or a short circuit, the state of the street lamp is not known unless the lamp is directly installed. There was a problem of low efficiency.

Accordingly, an object of the present invention is to solve the problems of the conventional street light control method, and detects whether the power supply is input to the street lamp in the power failure monitoring unit to check whether the power failure, if the power failure is confirmed commercial power It replaces the power and sends out the streetlight's identification code and power outage status data.In order to monitor the line status, the current of the line is measured and the streetlight's identification code and current measurement data are sent out. By detecting the status of the street lamp in real time by the remote server, it is possible to recover quickly in case of power failure or short circuit, thus preventing the waste of power, extending the life of the street lamp, and preventing accidents caused by the malfunction of the street lamp. It is to provide a street light remote control system that can prevent.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a street lamp remote control system according to the present invention, the street lamp monitoring device 100 checks the state of the blackout or the line of the street lamp 156 and transmits to the remote server 300 through the wireless base station 200 Then, the remote server 300 shows the data transmitted from the streetlight monitoring apparatus 100 to the administrator in real time, and accumulates the transmitted data.

FIG. 2 is a block diagram of a streetlight monitoring apparatus of a streetlight remote control system according to the present invention, and the analog signal of the current output from the commercial power supply unit 109 for supplying power and the sensor unit 106 for measuring current in a line. The signal is input to the converter 105 and converted into a digital signal, and then transmitted to the controller 104 and the power failure monitoring unit 102.

When the power supply from the commercial power supply unit 109 is maintained, the control unit 104 displays the identification code of the street light 156 and the state of the line measured by the sensor unit 106 through the electrostatic monitoring unit 102 and the modulation / demodulation unit. In step 110, the data is converted into data for wireless transmission and then transmitted through the transmitter 101.

At this time, when the power supply from the commercial power supply unit 109 is stopped, the power failure monitoring unit 102 replaces the power of the commercial power supply unit 109 with the power charged in the charging unit 103, the identification of the street light 156 The code and the power failure status data are transmitted through the transmitter 101.

In addition, when the street lamp 156 is directly controlled by the manager, the controller 107 may input desired data through the input unit 107, and the result may be confirmed through the display unit 108.

3 is a configuration diagram of a street lamp monitoring device of a remote control street light system according to the present invention, the power supply of the commercial power supply unit 109 for supplying power to the street lamp 156 and the street lamp monitoring device 100 is a circuit breaker 153, It is supplied to the street lamp 156 via the magnetic contactor 154 and the overload breaker 155, the commercial power source 109 is also connected to the converter 158.

The earth leakage breaker 153 serves to block input power when a line for supplying power to the street light 156 is short-circuited, and the magnetic contactor 154 is controlled by the main control device 152 to provide a street light 156. The on-off operation of the power supplied to the overload breaker 155 serves to cut off the input power when the input current exceeds the allowable range, thereby providing stable power to the street light 156. Supply.

At this time, the current detector 157 detects the current input to the street light 156 and transmits it to the converter 158.

The conversion unit 158 receives voltage and current from the commercial power supply unit 109 and the current detector 157, respectively, and converts the data into digital data and transmits the data to the main control unit 152 and the sub control unit 159. .

At this time, if the power supply is maintained from the commercial power supply unit 109, the main control unit 159 transmits the identification code of the street lamp 156 and the data received from the converter 158 to the wireless transceiver 151, the The radio transceiver 151 transmits the received data to the radio base station 200.

When the power supply is stopped from the commercial power supply unit 109, the sub-control device 159 transmits a control signal to the charging device 160 to charge the power charged from the charging device 160 to the wireless transceiver 151. At the same time, the sub-controller 159 transmits the identification code and the power failure state of the street light 156 to the wireless transceiver 151, and the wireless transceiver 151 transmits the received data to the wireless base station ( 200).

The present invention may be modified in various ways without departing from the basic concept according to the needs of those skilled in the art.

As described above, according to the present invention, since the remote server 300 can grasp the state of the street light 156 in real time and can quickly recover in the event of power failure or short circuit, it prevents waste of power and Extending the life and there is an effect that can prevent the accident due to the non-operation of the street light (156).
