Detailed ways

Embodiment of the present invention: street lamp wireless detection control system. Including street lamp 1 and monitoring center 2. A lamp head detection and energy saving controller 3 is installed on each street lamp 1, the lamp head detection and energy saving controller 3 is an integrated circuit module, installed in the light pole of the street lamp 1, 1 to 2 meters away from the ground, directly on the existing It can be installed on the street lamp without digging cable trenches or laying new cables. The lamp head detection and energy-saving controller 3 is composed of two parts: a lamp head detection module and an energy-saving control module. The composition of lamp cap detection module is as shown in accompanying drawing 2, is made of single-chip microcomputer 8 and the wireless receiving module 9 that is connected with this single-chip microcomputer 8, wireless transmission module 10 and lamp cap detection module 11; After the single-chip microcomputer 8 checks the received data, it transmits the data through the wireless transmitting module 10 and transmits it to the next street lamp detection terminal. The lamp head detection module 11 is used to detect the working status of street lamps such as on-off and light decay, and transmits the detected status to the wireless master controller 4 through the wireless transmission module 10 in a link mode when appropriate. The energy-saving control module is composed of an energy-saving controller 12 and a choke coil compensator 13, as shown in FIG. 4 . The energy-saving controller 12 is installed at the fuse position of the street lamp 1 , and the choke coil compensator 13 is connected to the energy-saving controller 12 . The energy-saving control module uses the choke coil compensator 13 to control the current and power output to reduce the power. After the street lamp is powered on, the energy-saving controller 12 controls the street lamp equipment to the full power state, and then according to the preset program, the street lamp lighting power And illuminance, automatically adjust the lighting illuminance of the road according to time. Its main circuit is shown in Figure 5, and the load Z is a high-pressure sodium lamp. Considering the ballast factor, the load is an inductive load. Due to the existence of inductance, the high current rise rate di/dt is limited, but because the current lags behind the voltage, when the current decreases to less than the bidirectional thyristor maintenance current and turns into blocking, the grid voltage has crossed zero and reached the next half cycle considerable magnitude. In this way, the bidirectional thyristor immediately bears the impact of a voltage step rise after it is turned off. To sum up, the non-contact switch for light-controlled street lamps has lower requirements for di/dt of bidirectional thyristors and higher requirements for dv/dt. In addition, considering the characteristics of the high-voltage sodium lamp load, the bidirectional thyristor is required to have sufficient ability to withstand surge current. In order to reduce dV/dt, appropriate resistance-capacitance absorption is designed at the grid input terminal and the two-way thyristor. For the 220V power supply voltage, the rated voltage of the bidirectional thyristor can be taken as 800V, and the rated current depends on the rated current of the device.

The trigger circuit of the energy-saving control module is shown in Figure 6. The AC voltage regulation special integrated circuit KJ 006 is selected. It has the advantages of good linearity of sawtooth wave, wide phase shift range, simple control mode, loss of communication protection, and large output current. , The output pulse width is adjustable within 100μs ~ 2ms by changing the resistance and capacitance parameters. When +15V power supply, the pulse width is greater than 13V, and the maximum output capacity is 200mA. The trigger circuit also uses a new type of thyristor trigger drive device MOC3061, which is a composite device composed of infrared LED and photoelectric bidirectional thyristor. It has the advantages of input and output isolation, one-way signal transmission, strong anti-interference ability, and small size. It is very suitable to replace the power amplifier circuit and pulse transformer to drive the bidirectional thyristor. In order to make the output voltage of the device stable at a given value reliably, the voltage feedback loop is corrected as a typical I-type system. In order to determine the specific structure and parameters of the regulator, an approximate dynamic structure diagram is established as shown in Figure 7. From Figure 7, the regulator can be specifically designed.

The energy-saving control module is a lighting energy-saving device based on microcomputer control technology. As shown in Figure 8, its main circuit is composed of two switching circuits in parallel, one is a microcomputer control circuit as the main circuit, and the other is an AC contactor as a bypass switching circuit, which is connected in parallel with the main circuit. When the main circuit fails, the main circuit will exit automatically, and the bypass switch will be automatically put into operation to ensure the normal operation of the light. The working mode of the main circuit is: a. Firstly, through the wireless network, the control of the time of turning on and off the lights every day is realized. After the street lamp is turned on, it should be fully charged for the first 10 minutes to ensure that the bulb is fully preheated and started to reach a normal working state. b. After the preheating period is completed, the microcomputer controls the voltage regulation of the converter, smoothly enters the ramp down period, and then automatically enters the first-level power-saving state, and maintains a stable power-saving operation. c. When used for road lighting control, because there are few cars and people in the second half of the night, in addition to setting the first-level power-saving level, enable the night light function in the second half of the night, that is, the second-level power-saving level, which can get better power-saving effects. Pedestrians and vehicle sensors are also installed in the energy-saving control module. The pedestrians and vehicle sensors are connected with the energy-saving controller 12, and the night light function is enabled in the second half of the night, that is, the secondary power-saving level. When pedestrians and vehicle sensors detect that pedestrians or vehicles pass by , through the wireless network, real-time transmission to the next N (1 to 3) street lamps in the direction of pedestrian or vehicle movement, the street lamp receives the control signal, then enters the first-level power-saving level from the second-level power-saving level, and waits for pedestrians or vehicles to pass After the street lamp is turned on, the street lamp enters the second-level power-saving state.

The structure of wireless general controller 4 is similar to the composition of above-mentioned lamp cap detection module, is made of wireless receiving module 9, wireless transmitting module 10, single-chip microcomputer 8, GPRS wireless communication module 5, and the data output end of wireless receiving module 9 is connected to single-chip microcomputer 8; The data input end of wireless sending module 10 connects single-chip microcomputer 8; One end of GPRS wireless communication module 5 connects single-chip microcomputer 8 by serial port, and the other end connects GPRS wireless communication network 6 by wireless signal, and the processing capacity of its single-chip microcomputer 8 is than the lamp cap detection module of street lamp. The single-chip microcomputer is strong, and two single-chip microcomputers can be used in practice, which is conducive to the simplification of the system.

In order to transmit the signal wirelessly, carrier transmission is required, that is, the baseband signal must be moved to a designated high frequency with less channel loss for transmission. The frequency is different, and the propagation equipment and information transmission effect are also different. From the consideration of the signal transmission characteristics of the street lamp terminal, ultrashort wave UHF can be used for wireless communication, and a specific frequency band can be selected, so that its communication is not regulated and does not require additional channel fees. Therefore, the wireless transmission module 10 of the present invention selects common high frequency (RF) AM Transmitter chip (ASK), which has the characteristics of mature short-distance wireless data transmission technology, simple function and small size, is more suitable for application in this system. This module adopts the AM communication method, the working frequency is 433MHZ, and the frequency stability is ±75KHZ, the frequency stability is extremely high, when the ambient temperature changes between -25 and +85 degrees, the frequency drift is only 3ppm/degree, the frequency stability of the SAW resonator is second only to the crystal; the transmission power is ≤500MW, Static current ≤ 0.1UA, emission current 3 ~ 50MA, working voltage DC 3 ~ 12V. When the voltage changes, the transmission frequency basically remains unchanged, and the receiving module matched with the transmitting module can receive stably without any adjustment. When the transmission voltage is 3V, the transmission distance in open space is about 20-50 meters, and the transmission power is small. When the voltage is 5V, it is about 100-200 meters. When the voltage is 9V, it is about 300-500 meters. When the transmission voltage is 12V, it is The best working voltage has better emission effect, the emission current is about 60 mA, the transmission distance in open space is 700-800 meters, and the emission power is about 500 milliwatts. When the voltage is greater than l2V, the power consumption increases, and the effective transmission power is no longer significantly improved. This set of modules is characterized by relatively large transmission power and relatively long transmission distance, which is more suitable for communication under harsh conditions. The module adopts ASK modulation to reduce power consumption. When the data signal stops, the transmission current drops to zero, and the data level should be close to the actual working voltage of the module, so that a higher modulation effect can be obtained.

The wireless receiving module 9 selects the RX3310A type chip of the superheterodyne receiving circuit. The data receiving module generally has two kinds of design circuits, that is, the super regenerative receiving circuit and the super heterodyne receiving circuit. The super-regenerative receiver has the advantages of simple circuit and low cost, so it is widely used, while the super-heterodyne receiver has higher price, strong temperature adaptability, higher receiving sensitivity, stable and reliable operation, strong anti-interference ability, and the product's The consistency is good, the radiation of the local oscillator of the receiver is low, there is no secondary radiation, the performance index is good, it is easy to pass the detection of FCC or CE standards, and it is in line with industrial use specifications. The core components of the superheterodyne receiving circuit are RX3310A chip and RX3400 chip. The performance of RX3400 is higher than that of RX3310A, mainly because of higher sensitivity, but the price is also much more expensive, which is suitable for high-demand systems. In this system, strive for high quality and low price, and try to choose components with lower price without affecting the reliability and safety of product work, so the present invention chooses RX3310A chip. RX3310A is a receiving integrated circuit specially used for ASK modulation wireless remote control and digital transmission signal produced by Taiwan HMARK Company. It contains low noise high frequency amplifier, mixer, local oscillator, intermediate frequency amplifier, intermediate frequency filter, comparator, etc. , is a frequency conversion superheterodyne circuit, double-row 18-pin wide-body SMD package, small size. The communication method of the module is AM, the working frequency is 433MHZ, the frequency stability is ±75KHZ, the receiving sensitivity is -102DBM, the static current is ≤5MA, the working current is ≤5MA, the working voltage is DC5V, and the output mode is TTL level.

The single-chip microcomputer 8 adopts the PIC12C508 single-chip microcomputer of MicroChip. The single-chip microcomputer has the following characteristics: 1) There are many models that can meet the application requirements of different levels, and the performance and price are high. 2) The PIC series 8-bit CMOS microcontroller has a unique RISC structure, a Harvard bus (Harvard) structure where the data bus and the instruction bus are separated, so that the instruction has the characteristics of a single word length, and the number of bits of the instruction code can be more than 8 bits. Compared with the traditional 8-bit single-chip microcomputer using CISC structure, it can achieve 2:1 code compression, and the speed is increased by 4 times; 3) There is no waiting for the product to go on the market. The low-cost OTP chip of PIC can make the single-chip microcomputer make the product appear on the market immediately after its application program development is completed; 4) PIC has a superior development environment. The real-time performance of the OTP single-chip microcomputer development system is an important index. When PIC launches a new model, it releases a corresponding simulation chip. All development systems are supported by dedicated simulation chips, and the real-time performance is very good; 5) its pins have Anti-transient ability, it can be connected to 220V AC power supply through a current-limiting resistor, and can be directly connected to the relay control circuit without optocoupler isolation, which brings great convenience to the application; 6) Thorough confidentiality. PIC protects the code with a confidential fuse. After the user burns the code and blows the fuse, others can no longer read it unless the fuse is restored. At present, PIC adopts deep-buried fuse technology, and the possibility of restoring the fuse is extremely small; 7) It has a built-in watchdog timer, which can improve the reliability of program operation.

The main device of the lamp head detection module 11 is a photoresistor, which is mainly used to monitor the brightness of the street lamp 1 and transmit the information to the single-chip microcomputer 8 . Lamp detection and energy-saving controller 3 is connected with wireless master controller 4 through wireless signal; wireless master controller 4 is connected with GPRS wireless communication network 6 through its GPRS wireless communication module 5, and GPRS wireless communication network 6 is connected to INTERNET 7, monitoring center 2. Connect to the Internet 7 (as shown in Figure 1) through the TCP/IP communication protocol. Lamp head detection and energy-saving controller 3 is used to detect the operation status of street lamp 1, and transmit the detected data to wireless master controller 4 through the link;

The wireless general controller 4 is used to receive the detection data from the lamp head detection and energy saving controller 3, and transmit the data to the monitoring center 2 through the wireless network. After the street lamp 1 is turned on for a period of time, the lamp head detection and energy-saving controller 3 will automatically obtain the on-off status of the street lamp 1 and send the data at an appropriate time. Between the street lamps 1 and between the street lamps 1 and the wireless master controller 4, the communication mechanism of multi-link diffusion propagation is used for communication. The specific transmission method is shown in Figure 9. System) data transmission scheme, the advantage of this method is that a higher accuracy rate of data transmission can be obtained with very few redundant symbols. When a street lamp is abnormal, the lamp head detection and energy-saving controller 3 of the street lamp sends a coded signal with the street lamp number and abnormal condition to the next street lamp through the wireless transmitting module 10, and the street lamp judges whether the signal is correct or not after receiving the signal. , if correct, then return a reply signal to the previous street lamp, and pass the signal to the next street lamp, and so on, until the signal is passed to the wireless master controller 4. If the signal is wrong or the lamp head detection and energy-saving controller 3 of a certain street lamp is damaged, the street lamp will repeatedly transmit signals to ensure that the signal can be transmitted. Take street lamp N-1 as an example, assuming that No. N-1 receives the wrong signal from No. N, it will not reply to the reply signal, and No. N street lamp will re-transmit the signal. If there is no reply signal, it will send several times in succession. Make sure that the N-1 street light can receive the signal. If the controller of No. N-1 street lamp is broken, and No. N street lamp will not receive the reply signal from No. N-1 after retransmitting many times, then No. N street lamp will send a signal to No. N-2. -No. 1 street light problem, No. N will also send multiple times in a row. If no reply signal is received, No. N will continue to send signals to No. N-3, and so on. The number of times to resend the signal can be modified. Here, it is assumed to be 3 times. When a controller is damaged, the upper-level controller can pass the signal to the next level, and the number of links can also be modified. According to the communication distance, we will The link is set to 3, that is, number N can transmit signals to street lights N-2, N-3, and N-4 under abnormal conditions.

For the rate selection of the communication data of this system. Since the data rate has a great influence on the communication distance, generally speaking, the higher the rate, the closer the distance. The maximum transmission data rate of the data module is 9.6KBs, which is generally controlled at about 2.5k. Too high a data rate will reduce the receiving sensitivity and increase the bit error rate. Generally, remote control devices do not need too high a rate, such as for single-chip microcomputers. The rate is 2.4kbps, and the transmission efficiency should be taken into account. When there are several consecutive "1" in the data and the pulse width exceeds 1ms, the transmission efficiency will decrease. Too large duty cycle and too low frequency will easily cause overmodulation. When the high-level pulse width is in the range of 0.1-1ms, Sending and receiving effect is better. Improper data rate will also affect the sending and receiving distance, and even the signal cannot be received. Therefore, the communication data rate in this system is selected as 2.4kbps, and when the signal transmission rate is 2400bps, the data transmission accuracy is ±2.5×10 ^-6 .

The communication protocol data frame format of this system is defined by itself, and its format is:

Realization of remote communication in this system: Since the IP address of the mobile terminal module logging on to the GPRS network is dynamically allocated by the gateway GPRS support node GGSN, and the remote control computer has an independent IP address, so before the communication is established, the user must first send a message containing the remote control The short message of the computer IP address and port number is sent to the mobile terminal module. After the mobile terminal receives the short message, it will establish a point-to-point link with the remote control computer as the main calling party. After the link is established, the data encapsulated by the TCP protocol can be communicated between the remote control computer and the mobile terminal. In the remote control program, the system creates two derived classes of CSocket, namely CServerSocket and CTransferSocket.
