In general, the system for street lamp lighting includes a flasher using a light detecting element that senses the illumination of day and night, and an electronic flasher (Timer) flashing by a predetermined timetable according to a program input, and a wireless control method that can be remotely controlled. The electronic flasher and the wireless control method are common, but most of the electronic flashers have an internal standard time error after installation, which makes the administrator inconvenient to correct the time regularly at the site. Wireless control systems are becoming commonplace.

However, the conventional wireless control method has a problem in that the control of the actual lighting of the street lamp can not be confirmed at the control station because only the remote control is possible at the central control station. In addition, even if a two-way radio system that can be checked remotely is implemented, each flasher must receive a frequency license from the Ministry of Information and Communication every day. Since there is no way to check the arrival and strength of the central wireless control signal by itself, some areas may not be able to be installed due to the inconvenience of selecting expensive installation equipment and the installation location due to its inconvenience. In order to realize the overload of the switchboard and the magnet sequential control to protect the device, delay timer and control box have to be configured in the switchboard separately from the flasher, which causes cost increase.

In addition, even in the case of other control systems, when a street lamp breaks down, it is necessary to go to the site and inspect and repair the existing wireless system. The existing wireless system focuses on the functions for remote control and monitoring only. In order to check and confirm the fault condition of the flasher, it is necessary to open the switchgear and disassemble the contact directly so that it is inconvenient to carry out the maintenance work of the site manager and the safety accident of the electrical contact is concerned. In addition, there is a problem in that manpower and cost are generated. On the other hand, a technique for lighting a lamp such as a street lamp, a security lamp and the like using a prior art flex protocol signal of the present applicant and a technique thereof are introduced in Japanese Patent Laid-Open No. 1999-64511. This time correction is performed by receiving flex protocol time information of wireless caller. In order for the light-off point through the field radio controller using a wireless remote control configured to achieve a self-timer control is impossible to realize the point off-site, open directly the distribution boxes for street lights are inconvenient problem that the light-off operation.

The present invention has been made to solve the above problems, wireless remote control from the central control center and remote control low power wireless control in the field is possible and wireless remote control in the field (lighting, lights out, differential control) It is possible to provide the wireless two-way auto flasher for street lamp lighting so that the administrator can check the arrival of the control signal and the intensity of the wireless signal from the central control center through the liquid crystal and the wireless two-way remote control with the level display for each grade.
