在具体实施过程中，所述控制器 12设置有多个手动控制开关，所述手动控 制开关对应连接所述第一继电器 CJ1、 第二继电器 CJ2以及第三继电器 CJ3。  In a specific implementation, the controller 12 is provided with a plurality of manual control switches, and the manual control switches are correspondingly connected to the first relay CJ1, the second relay CJ2, and the third relay CJ3.
本发明实施例的工作原理为：  The working principle of the embodiment of the present invention is:
在三相四线交流供电线路中设置开关电源 11 , 在开关电源 11的输入端和 输出端分别连接第一继电器 CJ1和第二继电器 CJ2, 在三相四线交流供电线路 设置第三继电器 CJ3 , 第三继电器 CJ3绕过开关电源连接到三相四线交流供电 线路的路灯类供线路上。 其中， 第一继电器 CJ1、 第二继电器 CJ2和第三继电 器 CJ3分别与控制器 12连接， 由控制器 12控制第一继电器 CJ1、 第二继电器 CJ2和第三继电器 CJ3的通断。 A switching power supply 11 is disposed in the three-phase four-wire AC power supply line, and the first relay CJ1 and the second relay CJ2 are respectively connected to the input end and the output end of the switching power supply 11, respectively, in the three-phase four-wire AC power supply line The third relay CJ3 is set, and the third relay CJ3 is connected to the street lamp type of the three-phase four-wire AC power supply line by bypassing the switching power supply. The first relay CJ1, the second relay CJ2, and the third relay CJ3 are respectively connected to the controller 12, and the controller 12 controls the on and off of the first relay CJ1, the second relay CJ2, and the third relay CJ3.
其中， 当第一继电器 CJ1 闭合， 开关电源 11 的输入端接通， 在无故障情 况下输出电压为 250Vdc的直流电，第二继电器 CJ2控制开关电源 11的输出端， 用于通断开关电源 11与 LED路灯之间的电路； 第三继电器 CJ3是路灯类供线 路的开关，第三继电器 CJ3闭合时，交流电将直接流到 LED路灯上。本发明中， LED路灯也是同时支持交直流供电。  Wherein, when the first relay CJ1 is closed, the input end of the switching power supply 11 is turned on, the output voltage is 250Vdc direct current in the case of no fault, and the second relay CJ2 controls the output end of the switching power supply 11 for switching the switching power supply 11 and The circuit between the LED street lamps; the third relay CJ3 is a switch for the street lamp type, and when the third relay CJ3 is closed, the alternating current will flow directly to the LED street lamp. In the present invention, the LED street lamp also supports AC and DC power supply at the same time.
请参阅图 2, 开关电源 11的输出端与检测报警器 13连接， 由检测报警器 13进行采样再判断， 并由检测报警器 13发出相应的信号到控制器 12, 控制器 12才 据信号控制相应的继电器的通断。  Referring to FIG. 2, the output end of the switching power supply 11 is connected to the detection alarm 13 and is sampled and determined by the detection alarm 13. The detection alarm 13 sends a corresponding signal to the controller 12, and the controller 12 controls the signal according to the signal. The corresponding relay is switched on and off.
显然， 本发明能够控制器控制三个继电器的不同通断状态， 可以在交流电 与直流电之间进行切换， 其中， 控制器 12的控制包括有自动控制和手动控制。  Obviously, the present invention can control the different on-off states of the three relays, and can switch between alternating current and direct current, wherein the control of the controller 12 includes automatic control and manual control.
其中，在自动控制中，通过对开关电源 11输出端的检测自动通断相应的继 电器：  Among them, in the automatic control, the corresponding relay is automatically turned on and off by detecting the output end of the switching power supply 11:
在三相四线交流供电线路开始通电时， 自动闭合第二继电器 CJ2并保持一 段时间， 然后自动闭合第一继电器 CJ1 , 这样开关电源 11的输入端和输出端的 电路都是通路。  When the three-phase four-wire AC power supply line starts to be energized, the second relay CJ2 is automatically closed for a period of time, and then the first relay CJ1 is automatically closed, so that the input and output circuits of the switching power supply 11 are both paths.
之后， 检测报警器 13开始对开关电源 11的输出端的电压进行检测， 若检 测到某一路的电压超出 220~280Vdc的范围， 则把报警信号反馈给控制器 12, 控制器 12控制断开第一继电器 CJ1 ,断开第二继电器 CJ2 ,闭合第三继电器 CJ3 , 通过上述步骤，控制器 12将供电线路切换为交流供电状态，保证了系统内 LED 路灯的正常工作。  Thereafter, the detection alarm 13 starts detecting the voltage at the output end of the switching power supply 11. If it is detected that the voltage of a certain path exceeds the range of 220 to 280 Vdc, the alarm signal is fed back to the controller 12, and the controller 12 controls the first disconnection. The relay CJ1 disconnects the second relay CJ2 and closes the third relay CJ3. Through the above steps, the controller 12 switches the power supply line to the AC power supply state to ensure the normal operation of the LED street light in the system.
在手动控制中，本发明的控制器 12上设置有三个手动控制开关，分别对应 控制电路的三种状态： 检修、 直流供电和交流供电： 当需要检修时，拔动对应检修的手动控制开关，使得第一继电器 CJ1闭合， 由检测报警器 13检测开关电源 11的输出电压； In the manual control, the controller 12 of the present invention is provided with three manual control switches respectively corresponding to three states of the control circuit: maintenance, DC power supply and AC power supply: When the inspection is required, the manual control switch corresponding to the inspection is pulled, so that the first relay CJ1 is closed, and the detection alarm 13 detects the output voltage of the switching power supply 11;
在需要直流供电时， 拔动对应直流供电的手动控制开关， 使得第一继电器 CJ1、第二继电器 CJ2闭合，则开关电源 11输入端和输出端均为通路状态， LED 路灯由开关电源 11提供的直流电进行供电；  When the DC power supply is required, the manual control switch corresponding to the DC power supply is pulled, so that the first relay CJ1 and the second relay CJ2 are closed, and the input end and the output end of the switching power supply 11 are all in the path state, and the LED street lamp is provided by the switching power supply 11 DC power supply;
在需要交流供电时， 拔动对应交流供电的手动控制开关， 使得第三继电器 CJ3闭合， 则三相四线交流电直接输送到 LED路灯。  When AC power is required, the manual control switch corresponding to the AC power supply is pulled, so that the third relay CJ3 is closed, and the three-phase four-wire AC power is directly transmitted to the LED street lamp.
本发明还提供一种 LED路灯， 所述路灯包括本发明提供的 LED路灯的控 制装置， 鉴于该装置在上文已有详细的描述， 此处不再赘述。  The present invention also provides an LED street lamp comprising the control device for the LED street lamp provided by the present invention. Since the device has been described in detail above, it will not be described herein.
