1 is a block diagram of a plurality of streetlight controllers in general unidirectional communication.

As shown in the figure, the overall control of a plurality of street light fixture system, for this purpose the main control unit 100 for generating a control signal, and a plurality of street lights for receiving a control signal of the main control unit to control the plurality of street light fixtures The controller 300 is controlled by a plurality of street light controllers and consists of a plurality of street light fixtures 400 illuminating the street.

Conventional plural street light controllers can selectively control the turning on / off of plural street light fixtures at a desired time from a long distance. This is a main controller that wirelessly transmits a control signal including an area code, which is a plurality of street light controllers. When the area code included in the control signal received by the 300 is the same as the area code of the comparison, if the same is made by analyzing the continuous control data to control the plurality of street light fixtures (400) assigned.

Such a plurality of street light controller can selectively control the point / off of the plurality of street light fixtures at a desired time from a long distance, which is the main control unit 100 wirelessly transmits a control signal including an area code, and the transmitted Receives a control signal from the plurality of street light controller 300 and compares whether the area code included in the control signal is the same as their area code, and if the same is analyzed by analyzing the continuous control data is made by controlling the plurality of street light fixtures (400) .

In general, the apparent power in the AC circuit is Pa, the active power P, and the reactive power Pr. When the voltage is V and the current is I, the relationship between power and power factor is as follows.

In AC circuits, reactive power is the power that reacts, that is, the energy that does not do anything when the AC voltage is applied to a load containing inductive components, which continually circulates between the power supply and the load. In the case of power and single-phase alternating current, when the voltage is V and the current is I, Pr = VIsinθ is calculated, and active power (P), which is the power actually consumed at the load, is calculated as P = VIcosθ.

In addition, the apparent power (Apparent power) is a value (Pa) generally used to represent the load of the AC load or the power supply, and in the case of single-phase alternating current, calculated as Pa = VI, cosθ, which is a ratio of the above-described effective power and apparent power. Is called power factor, which is usually expressed as a percentage and is ideally 100%.

On the other hand, in the AC circuit, when the load is an inductive load, when the AC power is an inductive load, when the AC power passes the inductive load, a ground current is generated and the current phase is earlier than the voltage phase. One power factor is lowered.

In addition, the reactive power continuously circulating between the AC power supply and the load increases without doing anything, and the power loss due to the high load of the power line or the pole transformer increases, and the additional equipment cost such as the expansion of the transformer capacity is added. do.

At this time, in order to improve the power factor of the AC power line to 98% or more, the power factor is improved by connecting a capacitor having a capacitive component, which is a capacitance, in parallel with an inductive load to generate a phase current. Reduced power loss and equipment costs.

However, power factor correction of power lines to which a large amount of inductive loads are applied, such as a number of streetlight fixtures and security lamps using coil type ballasts, in which inductive loads are gradually increasing. If the power consumption is variable from time to time, and if there is a significant fluctuation in load, such as when lighting a large number of street lamps and security lamps in a symmetrical manner, the power loss increases due to the power factor drop of the driving power line and the effectiveness of the electrical equipment. Since the utilization rate has been reduced and power factor compensation is required immediately, the automatic power factor adjustment and the power integration function can be used to monitor and control the power factor adjustment remotely, collect accumulated power and accumulated reactive power, and monitor the power line condition. There is a need for an automatic power factor adjustment device with communication capability. The method of reducing the power loss by canceling the overvoltage or undervoltage supplied from the line is less effective than the technology.When receiving the control signal from the main controller, the receiving module is crystal type, so it is difficult to change the frequency band. In order to use a number of street light controllers in the neighborhood, a problem arises in that the crystal of the RF receiving module needs to be replaced, which causes a problem of cost increase.

The present invention has been made to solve the above problems, a capacitor is mounted on a plurality of street light controller to provide a cost reduction by integrally connected to a plurality of street light fixtures, by connecting each switch of the insulation resistance tester integrally By checking the insulation resistance between the line and the ground or between the lines, it is possible to check the insulation resistance status or determine whether the door is open or closed, and automatically detect the change in the power factor of the load line of a plurality of street light fixtures. The power factor is divided into four or more stages so that the power factor is automatically compensated until the preset power factor reference value is reached.The power factor of the power line is reduced by adjusting the power factor of the power line to which an inductive load using single phase power is applied.
