一种路灯节能控制系统A street light energy saving control system

技术领域technical field

本发明属于电子技术领域，尤其是涉及一种采用了电力载波技术的智能化路灯节能控制系统。The invention belongs to the field of electronic technology, and in particular relates to an intelligent street lamp energy-saving control system using power carrier technology.

背景技术Background technique

随着科技的进步，经济的发展，能源问题越来越受到国家的重视，“创建节约型社会”正在各行业中得到贯彻落实。目前各大城市的交通路灯的能源利用率不高，特别是子夜过后，城市交通道路上的车辆与行人较为稀少，但路灯却长亮不止，直至清晨，人、车稀少的道路上，仍然保持较高照明度的照明显然是没有必要的，这不仅缩短了照明灯具的使用寿命，还浪费大量的电能，也不利于我国节约型社会的建设。With the advancement of science and technology and the development of the economy, the energy issue has been paid more and more attention by the state, and "creating a conservation-oriented society" is being implemented in various industries. At present, the energy utilization rate of traffic lights in major cities is not high. Especially after midnight, there are few vehicles and pedestrians on urban traffic roads, but the street lights are always on. Higher illuminance lighting is obviously unnecessary, which not only shortens the service life of lighting fixtures, but also wastes a lot of electric energy, which is also not conducive to the construction of a conservation-oriented society in our country.

交通道路上的路灯没有必要时时全部打开，可以在适当时间段关闭部分路灯，如隔一个开一个，或隔两个开一个，对于车辆与行人特别稀少的交通道路则可以关闭更多的路灯。长时间以来，道路照明的控制方式一直处于较为落后的状态，一般来说，主要是采用人工手动控制、定时控制、光照控制或以上几种控制的组合等方式，但这些技术解决不了上述问题。还有的通过增装路灯节能控制器来控制路灯，但这需要重新布线，无疑会耗费大量的人力物力。现有技术不能满足日新月异的城市建设需要。It is not necessary to turn on all the street lights on the traffic road all the time. You can turn off some street lights at an appropriate time period, such as turning on one at a time, or turning on one at a time. For traffic roads with few vehicles and pedestrians, you can turn off more street lights. For a long time, the control methods of road lighting have been in a relatively backward state. Generally speaking, manual control, timing control, light control or a combination of the above control methods are mainly used, but these technologies cannot solve the above problems. Others control street lamps by installing additional street lamp energy-saving controllers, but this requires rewiring, which will undoubtedly consume a lot of manpower and material resources. Existing technology can't satisfy the ever-changing urban construction needs.

二、从图2-4可以看出路灯节能控制系统的工作原理：2. From Figure 2-4, we can see the working principle of the street lamp energy-saving control system:

1、控制中心部分的工作原理1. The working principle of the control center

控制中心原理框图如图2所示，控制中心可以有两种工作方式：主控制终端直接控制方式和微机通过单片机控制方式。采用主控制终端直接控制方式时，控制中心只有一个主控制终端即可完成对路灯的控制，控制信号由单片机发出，经KQ-300进行FSK调制，然后信号经放大电路、耦合电路耦合到电力网。路灯工作状态信号由电力网经耦合电路、滤波电路传至KQ-300，KQ-300对信号解调后送至单片机。采用微机控制方式时，控制信号由微机发出，经串口传至主控单片机，单片机对信号加工处理之后传送至KQ-300，KQ-300对信号进行FSK调制，然后信号经放大电路、耦合电路耦合到电力网。路灯工作状态信号的传输与单片机控制方式基本相同，只是信号最后经串口传送至微机。The functional block diagram of the control center is shown in Figure 2. The control center can have two working modes: the direct control mode of the main control terminal and the microcomputer control mode through the single-chip microcomputer. When using the direct control mode of the main control terminal, the control center only has one main control terminal to complete the control of the street lamps. The control signal is sent by the single chip microcomputer, modulated by FSK through KQ-300, and then the signal is coupled to the power network through the amplifier circuit and the coupling circuit. The working status signal of the street lamp is transmitted to KQ-300 from the power network through the coupling circuit and filter circuit, and KQ-300 demodulates the signal and then sends it to the single-chip microcomputer. When the microcomputer control mode is adopted, the control signal is sent by the microcomputer and transmitted to the main control single-chip microcomputer through the serial port. The single-chip microcomputer processes the signal and then transmits it to KQ-300. to the power grid. The transmission of the working state signal of the street lamp is basically the same as the control method of the single chip microcomputer, but the signal is finally transmitted to the microcomputer through the serial port.

2、中继器部分的工作原理2. The working principle of the repeater part

中继器原理框图如图3所示，该部分的主要功能是对信号的再生和放大。电力网上衰减后的信号经耦合电路、滤波电路及KQ-300解调后传至单片机，单片机完成对信号的存储，完成信号的接收功能；接收信号经单片机控制延时后送至KQ-300进行调制，然后经放大电路、耦合电路耦合至电力网，这样就完成了信号的再生与放大功能。The functional block diagram of the repeater is shown in Figure 3. The main function of this part is to regenerate and amplify the signal. After the attenuated signal on the power grid is demodulated by the coupling circuit, filter circuit and KQ-300, it is transmitted to the single-chip microcomputer. The single-chip microcomputer completes the storage of the signal and completes the signal receiving function; Modulation, and then coupled to the power grid through the amplifier circuit and the coupling circuit, thus completing the regeneration and amplification of the signal.

3、从控制终端部分原理3. Part of the principle from the control terminal

从控制终端原理方框图如图4所示，控制信号经耦合电路、滤波电路及KQ-300解调后传至单片机，单片机对信号进行识别后发出相应的指令完成对路灯的控制，声、光传感器传来的信号经单片机处理后产生相应的指令完成对路灯的控制。传感器、路灯等的工作状态信号经单片机传至KQ-300，KQ-300对信号进行调制后，信号经放大电路、耦合电路耦合至电力网。The schematic block diagram of the control terminal is shown in Figure 4. The control signal is demodulated by the coupling circuit, filter circuit and KQ-300 and then transmitted to the single-chip microcomputer. The incoming signal is processed by the single-chip microcomputer to generate corresponding instructions to complete the control of the street lamp. The working status signals of sensors and street lamps are transmitted to KQ-300 through the single-chip microcomputer. After KQ-300 modulates the signals, the signals are coupled to the power grid through the amplifier circuit and the coupling circuit.

T transceiver state control pin), is at low level under the control of the single chip microcomputer, KQ-300 is in the modulation and transmission state, after KQ-300 receives the control signal, it will modulate the control signal to the frequency of 125 ~ 131KHZ, the modulation signal is from 1 Pin (OTX1 carrier signal output pin), 2 pin (OTX2 carrier signal output pin) output carrier signal. After the carrier signal is amplified by the amplifying circuit composed of transistors Q1 and Q2, it is coupled to the power line by the coupling transformer KQ5, the adjustable inductor KQ4 and the capacitor CDY.

接收信号时，由从控制终端发出的信号由电容C1、C2经耦合变压器KQ1从电力线上耦合下来，耦合下来的载波信号发送到KQ-300输入端11脚(IRX载波信号输入脚)，此时，KQ-300的5脚(R/T收发状态控制脚)，在单片机的控制下处于高电平，KQ-300处于解调接收状态，KQ-300接收到耦合信号后，将耦合信号解调出来，解凋信号由8脚(RX解调后的数据输出脚)送至单片机5脚(P1.5脚)模拟单片机串口接收，而后由单片机对从控制终端的状态进行判断。When receiving the signal, the signal sent from the control terminal is coupled from the power line by the capacitors C1 and C2 through the coupling transformer KQ1, and the coupled carrier signal is sent to theinput terminal 11 of KQ-300 (IRX carrier signal input pin), at this time , the 5th pin of KQ-300 (R/T transceiver state control pin), is at high level under the control of the single-chip microcomputer, KQ-300 is in the demodulation receiving state, after KQ-300 receives the coupling signal, it will demodulate the coupling signal Come out, the demodulation signal is sent from pin 8 (data output pin after RX demodulation) to pin 5 (P1.

如果使用微机作为控制中心，则主控单片机需通过串行口和232电路与计算机通信，形成PC机控制系统。If a microcomputer is used as the control center, the main control single chip needs to communicate with the computer through the serial port and 232 circuit to form a PC control system.

主控制终端部分软件流程图如图6、图7所示，其程序由主控制终端主程序和主控制终端查询子程序组成。Part of the software flow chart of the main control terminal is shown in Figure 6 and Figure 7, and its program is composed of the main control terminal main program and the main control terminal query subroutine.

中继器部分原理电路图如图8所示，电力网上衰减后的信号由中继器进行恢复，经放大后耦合至电力网。其收发过程与主控制终端类似，但软件流程与主控制终端不同。组成部件与主控制终端也大致相同，不同之处是中继器的单片机外围有存储器，用于存放和读取暂存数据。The schematic circuit diagram of part of the repeater is shown in Figure 8. The attenuated signal on the power grid is restored by the repeater and coupled to the power grid after being amplified. Its sending and receiving process is similar to that of the main control terminal, but the software flow is different from that of the main control terminal. The components are roughly the same as the main control terminal, the difference is that there is a memory on the periphery of the single-chip microcomputer of the repeater, which is used to store and read temporary data.

中继器程序流程图如图9所示，中继器对电力线上传输的信号接收、暂存、放大后耦合至电力网，完成对信号的恢复和放大。The program flow chart of the repeater is shown in Figure 9.

从控制终端与电力线间信号的收发过程与主控制终端收发过程大致相同。接收时，单片机对接收到的控制信号进行解调、识别和处理，而后，由P2口发出控制信号来控制路灯。声光控电路发出的控制信号送至单片机的P0口，经单片机处理后送至P2口，由P2口发出控制信号来控制路灯。The process of sending and receiving signals between the slave control terminal and the power line is roughly the same as that of the master control terminal. When receiving, the single-chip microcomputer demodulates, identifies and processes the received control signal, and then sends a control signal from the P2 port to control the street lamp. The control signal sent by the sound and light control circuit is sent to the P0 port of the single-chip microcomputer, and then sent to the P2 port after being processed by the single-chip microcomputer, and the control signal is sent by the P2 port to control the street lamp.

从控制终端软件流程图如图11所示。从控制终端从电力网上接收来自主控制终端的控制指令，根据指令将路灯置于相应的工作状态，并将路灯的工作状态发送至电力网，由电力网将信号传至控制中心。The flow chart of the slave control terminal software is shown in Figure 11.
