The present invention relates to a remote control device such as a street light and security installed in a highway, an interchange, a city street, a critical facility such as a tunnel, a port, a security facility, and the like. By this, the lighting relationship of the street lamp can be controlled remotely quickly and effectively, and the security and power saving effect can be obtained by uniformly managing the irregular lighting and lighting time.

In general, street lamps and security lights are installed in various places around important facilities, and they usually provide nighttime lighting to achieve their intended purpose, such as traffic communication, security, and methods. Results in exposure.

Therefore, in order to protect important facilities in case of emergency, the necessity of quick and effective light control is urgently required for street lamps and security lamps. In many cases, the desired lighting purpose has been lost.

Conventional streetlight control methods are automatically turned on and off depending on the amount of light detected by a light dose cell (cds) that detects the illuminance around the streetlight, and methods of turning on and off according to a set time of a timer installed around a road. The control method by the gens (cds) turns on and off faithfully according to the amount of illumination around the street lights, but it is impossible to control the light unless the power is cut off.

In addition, street light power is used in parallel with the power supply for business, general purpose, industrial use, so there is a problem such as paralyzed work or emergency power in the case of batch power failure.

On the contrary, in the method of controlling a street lamp by a timer, since a control box having a timer is installed on the street around the street lamp, the operator has to move to the control box to control the time. There is a problem that can not be.

Therefore, when training is not performed in a timely manner, the effect of training is not only halved, but in case of an actual situation or an emergency, there is a problem other than the overall interruption.

The present invention was devised to solve the above problems, and in the control station, a transmitter for transmitting a radio signal by processing a light out signal, a lighting signal, and a street light ID signal as a serial signal is installed, and the street light has a photoconductive cell ( cds) and street light manipulators, but receivers that amplify, detect and decode radio wave signals from control stations are installed in conjunction with street light manipulators. OFF, and in the case of emergency or civil defense training, the equalization relationship of the street lamp according to the wireless control of the control station is made to be made easy as follows in detail according to the accompanying drawings, preferred embodiments of the present invention.

Figure 1a is a block diagram of the remote control device of the present invention, the signal processor (4) for processing the street signal ID signal (1), the extinguishing signal (2), the lighting signal (3) as a serial signal and the radio signal radio waves It consists of the transmitter (5) which transmits the signal.

FIG. 1B is a block diagram of the present invention. When the light around the street light is received by the photoconductive cell 7, the photoconductive cell 7 detects it and outputs it as a current signal. The analog current value outputted from the A / S converter 8 is converted into a digital signal to be input to the signal decoder 9, and the signal decoder 9 is connected to the street lamp manipulator 14 so that the street light is bright. The lamp is turned off, and if the street is dark, the lamp is turned on.

In addition, after receiving the serial signal coming from the antenna of the control station transmitter (5) with a receiving antenna and performing high frequency amplification (10), intermediate frequency amplification (11) and detection (12), the detected signal is decoded (9). Connect to enter.

The signal decoder 9 has a street lamp unique number 13 assigned to each street lamp to be stored in memory, and an appropriate number of street lamps L are connected to the street lamp manipulator 14 connected in parallel.

[Not described]

15, the photoconductive cell of the transmitter

Numeral 16 denotes a timer for setting the sunset time and sunrise time of the transmitter.

The present invention configured as described above is to install a street lamp operation receiver (b) in which a suitable number of street lamps are connected in parallel to each street, region, living zone, facility, etc. ) By assigning a streetlight unique number 13 for each memory, and registering the streetlight unique number 13 in the control unit's transmitter (a) to remotely control the entire streetlight operation receiver (B) according to the controller's control intention. Wireless control can be performed to enable group light control for the entire street light or partial light control for only street lamps in an area where an emergency occurred.

That is, normally, the analog value of the photoconductive cell 7 is converted into a digital signal in the A / D converter 8 and then input to a comparator in the signal decoder 9, and the input signal is comparator in the signal decoder 9. When compared with the reference signal set in the reference signal is more than the reference signal is recognized as a bright street light street (L) is turned off, the street around the street (L) is dark, the photoconductor cell (7) from the signal decoder 9 in the comparator (9) If the transmitted signal is below the reference signal, the periphery of the street lamp is recognized as dark and the street light manipulator 14 is turned on to turn on the street lamp.

In addition, the photoconductor cell 15 sensor and a timer 16 capable of setting a time can be connected to the signal processor 4 of the control station so that it can be used alternatively, but immediately after sunset time, the lighting signal 3 immediately after sunrise time. The light-off signal 2 is sent out so that the light-conducting cell 7 is turned on again and turned off even when the street light L is turned on and off by the light-conducting cell 7 of the receiver just before sunset and just before sunrise. Even if it breaks down, the street lamp is sure to operate. When lighting control and extinguishing is required by emergency or training, the controller sends out the ID signal (1) and the extinguishing signal (2) of the desired street lamp. 5) the radio call through the signal is received by the antenna of the entire streetlight operation receiver (b) that is always operating in the standby state, the high frequency amplifier (10), the intermediate frequency amplifier (11), and the detector (12) is a signal decoder ( Entered into 9) No. 1, only two, three, four street lamp group specified as shown in Fig. 2b is OFF.

When the release signal is issued when the need for light control or extinguishing is eliminated, the desired streetlight ID signal 1 and the lighting signal 3 are transmitted from the transmitter 5 and the signal decoder of the receiver I which is waiting ( 9) turns on the streetlight manipulator 14 of the streetlight group that was turned off by comparison, and the streetlight L is turned on.

Conventional photoelectric switch type street lamps use separate photoconductive cells for each streetlight, so that the lighting time and the lighting time do not coincide with each other as shown in FIG. Although the street lamp may be turned on all day or turned off all day due to the failure of the conductive cell, in the present invention, a plurality of street lamps connected in parallel by one receiver and the street lamp manipulator are simultaneously turned on and off, thereby reducing the power loss and fear of failure. Resolved.

As described above, the present invention not only reduces power loss and failure, but also has the effect of protecting the important facilities by making a quick and effective light control by radio wave in case of emergency by the command issued by the controller.
