KR20020028726A - Method and apparatus for indicating failure status of multiple lights and ballasts in one place - Google Patents

Abstract

PURPOSE: An apparatus for displaying failure states of lamps and stabilizers at one location is provided to confirm failure states of all of street lamps by a center controlling device and transmitting and receiving devices. CONSTITUTION: An apparatus for displaying failure states of lamps and stabilizers comprises a main controller(200) and a subcontroller The main controller includes a communicating unit(55) for communicating with the subcontroller, a displaying unit(99) for displaying a failure spot and a failure part, a power supply(66), and a CPU(77). The subcontroller includes a communicating unit(55) for communicating with the main controller(200), a stabilizer failure detector, a lamp failure detector, a power supply(66), a switch(88), and a CPU(77). The subcontroller communicates failure states of the stabilizers and lamps with the main controller(200). The main controller(200) sequentially displays failure data from the subcontroller by manipulating the switch(88).

Description

Method and device for displaying failure status of multiple lights and ballasts in one place {.}

Currently, there is a way to check whether there is an abnormality of the street light at night with the naked eye or check the ballasts of the street lamps one by one. Currently, the products currently being developed and used are paying a lot of money both economically and in terms of manpower.

In order to solve the problems of current inconvenience, time, and cost, it is a technical problem to develop a central control unit and a transmission / reception unit that can check all street lamps for abnormalities.

1. The failure status display device of the luminaire of the present invention is composed of the Main Controller (200) and the Sub Controller (100).

2. The main controller 200 includes a communication unit 55 for communicating with the Sub 100, a display unit 99 for indicating a fault location and a fault portion, a power supply unit 66 for supplying power, and a CPU for arithmetic control. .

3. The sub controller 100 has a communication unit (⑤) which communicates with the main, a ballast failure detection unit (③), a lamp failure detection unit (④), a power supply unit (⑥) for supplying power, and a switch for determining each sub controller (100). It consists of negative (8) and the CPU that controls this.

4. Detecting the failure status in Sub transmits the status of ballasts and lamps attached to each luminaire to the Main Controller using communication lines.

5. In Main, display the fault data transmitted from each device in order by switch operation. The fault data can be deleted by simple switch operation after repair.

6. Figure 3 is a flow chart of the operation of Sub. Except for general lamp which power is turned on, in case of discharge lamp, after a certain time delay, check status of ballast and lamp status, and store data of place and failure status. Then communication from Main is received and stored data is transmitted.

7. Figure 4 is a flow chart of the operation of Main. Normal lamps that are powered on are excluded, but in the case of discharge lamps, communication starts sequentially after a certain time delay. When the fault data is received, it saves and displays the point and fault part (lamp or ballast) and tries to communicate with the next luminaire.

At present, there are many economic losses in the country due to the inconvenience, time required for checking the abnormality of numerous street lights and security lights after sunset, and the demand for many manpower.

In addition, since the trouble spot can be easily taken in a short time, the purpose is to pursue the safety of road traffic.
