Description

TECHNICAL FIELD

[0001] The present application relates to the field of wireless monitoring systems for urban road lighting or highway tunnel lighting, in particular to wireless energy consumption monitoring and electricity stealing monitoring of a wireless lighting monitoring system, and specifically to a LoRa wireless urban road lighting energy consumption and electricity stealing monitoring method and system. BACKGROUND

[0002] With the rapid development of urbanization in China, the number of urban road lighting street lamps gradually increases, and the lighting electricity consumption further increases. Urban road lighting is a major consumer of urban energy consumption and an important guarantee for night road traffic safety. LED lamps are widely used in urban road lighting to replace traditional lighting sources due to their high luminous efficiency, long service life, adjustable light, energy saving and environmental protection. The commonly used LED lamps use control cables to provide dimming control signals for their driving power supplies. The number of LED lamps in the urban road lighting system is large, and the required cable laying engineering quantity and comprehensive construction cost are high, which is difficult to implement. It is difficult to achieve flexible control strategy of LED lamps, unable to monitor the running state of LED lamps, and unable to fine control LED lamps.

[0003] With the development of Internet of Things technology, ZigBee, WiFi, LoRa, NB-IoT and other wireless communication technologies are gradually applied to wireless control and state monitoring of urban lighting systems. LoRa technology is a wireless technology for Internet of Things, which has the advantages of long distance, low power consumption, low cost, large coverage capacity, etc., and is suitable for long-distance transmission of small data volume of Internet of Things terminal equipment. And LoRa adopts a star network, has strong expansion capability, mature industry chain, strong transmission capability, long communication distance, flexible networking, and wider use value. Compared with ZigBee and WiFi, LoRa has longer communication distance, stronger anti-interference ability and larger capacity; compared with NB-IoT and other wireless communication technologies based on telecom operator base station communication, LoRa users can build private communication networks without paying communication operation fees to telecom operators, and the cost is relatively lower. Therefore, applying LoRa in urban road lighting systems has obvious advantages. Combining LoRa wireless communication technology with effective energy-saving lighting control strategy, intelligent control and data monitoring of urban lighting can effectively reduce lighting electricity consumption and achieve sustainable development.

[0004] The existing lighting system usually directly collects total energy consumption and other power data on the lighting power supply circuit to analyze the system energy consumption, but with the development of smart city, the lighting power supply circuit not only accesses LED lamps, but also accesses a large number of LED screens, cameras and other electrical equipment, so that the energy consumption data of the lighting power supply circuit is no longer single lighting power data. Therefore, directly using the power supply circuit energy consumption data cannot accurately obtain the lighting energy consumption, and cannot effectively evaluate the energy saving effect of the intelligent lighting system strategy.

[0005] Since LoRa is a kind of half-duplex communication technology with low communication rate, even if the cumulative energy consumption and other power data of the electrical equipment can be wirelessly collected by LoRa, it is difficult to synchronously collect the running energy consumption and other power data of multiple lamps and other electrical equipment of the lighting system at the same time, which is not conducive to accurate analysis of the lighting energy consumption. SUMMARY

[0032] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0033] The existing realization of lighting system energy consumption analysis needs to obtain the energy consumption and other power data of all electrical equipment in the system at the same time, but the low-rate half-duplex wireless communication LoRa cannot complete the wireless collection of data of a large number of devices at the same time. The LoRa wireless urban road lighting energy consumption and electricity stealing monitoring method provided by the present application can solve the problem that the LoRa wireless communication technology cannot realize the wireless synchronization collection of energy consumption and other power data of a large number of electrical equipment in the urban road lighting system at the same time, and realize the synchronization collection of power data of a large number of devices in the lighting system at the same time.

[0034] Further, the application also analyzes the synchronous collected power data, calculates the difference between the total power of the loop at the same time and the power of the lighting and other electrical equipment, judges the electricity stealing behavior, solves the problem of electricity stealing monitoring of the lighting system through LoRa wireless, and realizes the LoRa wireless electricity stealing monitoring of the lighting system.

[0035] As shown in Figure 1 It is a LoRa wireless city road lighting energy consumption and electricity stealing monitoring system architecture diagram, mainly including a centralized controller, a smart meter, a LoRa wireless LED lamp driving power supply, and a LoRa wireless data collector. The LoRa wireless LED lamp driving power supply and the LoRa wireless data collector constitute the LoRa wireless network monitoring object node of the system, which is simply referred to as a network node. The LED light source in the figure is a lighting fixture, and the electrical equipment 1~electrical equipment m is an LED advertising screen, an environmental monitoring device, a camera and other electrical equipment.

[0036] The smart meter measures the total energy consumption and other power data of the power supply loop. The driving power supply controls the dimming of the LED lamp and collects the power data of the LED lamp. The data collector collects the power data of the electrical equipment.

[0037] The centralized controller communicates with the smart meter through RS485 and communicates with the network node through LoRa, synchronously acquires the cumulative energy consumption and other power data of the electrical equipment, runs the lighting intelligent control and the lighting energy consumption and electricity stealing monitoring method, and realizes the intelligent control of the city lighting and the lighting energy consumption and electricity stealing monitoring.

[0038] The lighting energy consumption and electricity stealing monitoring method is mainly realized through the centralized controller and the LoRa network node, and is mainly realized in two steps: the first step is to make all network nodes in the system at the same time T i Collect the power data of the electrical equipment and save it; the second step is to acquire the power data of all electrical equipment in time after T i , realize the synchronous collection of the power data required for the system lighting energy consumption analysis.

[0039] Then, the power, cumulative energy consumption of the LED lighting lamps and other electrical equipment of the lighting system at T i , and the total power and total cumulative energy consumption of the lighting system are calculated and counted, the energy consumption analysis is realized; the total power of each phase collected by the smart meter is compared with the sum of the power of the LED lighting lamps and other electrical equipment of the same phase, the loop electricity stealing monitoring is realized.

[0040] The detailed steps are as follows:

[0041] Step 1: The centralized controller broadcasts the T i time power collection and saving instruction to all network nodes, T iThe value of T is:

[0042] T i = T 0 + (j - 1)ΔT (1)

[0043] In the formula, T s 0 is the initial collection time of the centralized controller each day, ΔT is the energy consumption monitoring period, which needs to be greater than the longest time T max required by the system polling communication and operation energy consumption and electricity larceny monitoring strategy i , j is the monitoring order each day, j ∈ {1, 2, 3,..., j max}, the monitoring order is updated after each system polling communication, so that T max is updated; when j < j max , j is increased by 1 after the polling communication is completed; when j = j max , j = 1 is set, so that the initial collection time of the next day is T max 0; j max satisfies:

[0044] (j max -1)ΔT = 24h (2) The broadcast power collection and preservation instruction is sent after the previous energy consumption and electricity larceny monitoring strategy is executed, and the sending time T f is:

[0045] T f = T i -Δt j (3)

[0046] Δt j is greater than the time required for all network nodes to receive the broadcast power collection and preservation instruction, and the minimum value of the monitoring period ΔT min satisfies:

[0047] ΔT min ≥ T s + Δt j (4)

[0048] Step 2: After each network node receives the broadcast collection and preservation instruction, the instruction is parsed to obtain T i , the system internal clock t is read, and the time difference Δt c is calculated:

[0049] Δt c = T i - t (5)

[0050] The time difference Δt c is timed by using the interrupt mode of the CPU self-timer module, and in the timing interrupt service subroutine, that is, at the time T i , the voltage, current, power and cumulative energy consumption of the electrical equipment collected at that time in the internal electric energy metering chip are read and saved to the specified storage unit group;

[0051] Step 3: The centralized controller collects the smart meter data through the serial port at T i , and obtains the total power P i and total energy consumption Q hk of each phase at T hk ;

[0052] Step 4: The centralized controller polls and broadcasts the data feedback instruction containing the node ID information to the network nodes after a proper time delay at T i , collects the power data of the network nodes at T i , realizes energy consumption analysis and electricity stealing monitoring, and waits to receive the power data of the network nodes at T i ;

[0053] Step 5: After receiving the data feedback instruction, the network node analyzes the instruction. If the ID in the instruction is consistent with the node's own ID, the network node uploads the power data at T i stored in the specified storage unit to the centralized controller;

[0054] Step 6: The centralized controller receives and saves the power data at T i returned by the network nodes according to the polling collection sequence of the network nodes on each phase power supply loop. After receiving all the node data, the centralized controller calculates and saves the LED single lamp power P i and cumulative energy consumption Q kn of the nth LED lamp connected to the phase at T kn , and the power P skm and cumulative energy consumption Q skm of the mth other electrical equipment, n∈{1,2,3,...,N k}, N k is the number of LED lamps connected to the kth phase, m∈{1,2,3,...,M k}, M k is the number of other electrical equipment connected to the kth phase, k∈{1,2,3;1=A,2=B,3=C};

[0055] If the centralized controller does not receive the feedback data of the queried network node in a certain time, it is marked that the node has a communication failure.

[0056] Step 7: The centralized controller calculates the LED lighting lamp power P i , lighting cumulative energy consumption Q k , total lighting power P k , and total cumulative energy consumption Q lamp of each phase of the power supply loop at T lamp :

[0057]

[0058]

[0059]

[0060]

[0061] Step 8: Centralized controller statistics T i all other power consumption devices of each phase of the power supply circuit P sk , cumulative energy consumption Q sk and total power P rest , total cumulative energy consumption Q rest :

[0062]

[0063]

[0064]

[0065]

[0066] Step 9: Calculate the power consumption difference ΔP k of each phase:

[0067] ΔP k = P hk - (P k + P sk ) (14)

[0068] Step 10: Compare the power difference and set the electricity stealing flag S k :

[0069]

[0070] ΔP k is less than ΔP ke , the kth phase power supply circuit power consumption is normal, and there is no electricity stealing behavior, then set S k = 0; otherwise, there is electricity stealing behavior on the kth phase power supply circuit, then set S k = 1; ΔP ke represents the electricity stealing monitoring judgment threshold value;

[0071] Step 11: When there is electricity stealing behavior, i.e. S k = 1, calculate the electricity stealing power P qk generated by the phase circuit:

[0072] P qk = ΔP k (16)

[0073] The centralized controller has system control functions of loop control and state monitoring of urban lighting system, wireless dimming and switch control of lamps, lamp state monitoring, and electric meter data acquisition, executes intelligent control strategy, and executes software of the two-step wireless communication, time-sharing synchronous data acquisition, lighting energy consumption and electricity stealing monitoring method of the application.

[0074] The software program flow chart of the centralized controller executing the energy consumption and electricity stealing monitoring method is shown in Fig. 2. Figure 2 The centralized controller can call the software program to realize the energy consumption and electricity stealing monitoring functions of the lighting system in the main program.

[0075] Step 1: The centralized controller reads the system time T n and T j , ΔT, Δt set by the system, and calculates T i , T f , j max by formula (1)-(3);

[0076] Step 2: Read the number N k , M k of each phase power equipment set by the system, and assign variable initial values p=0, m=n=j=k=1;

[0077] Step 3: When T n =T f , broadcast T i time power acquisition and storage instruction;

[0078] Step 4: When T n =T i , acquire electric meter data P hk , Q hk through serial port, delay for appropriate time, and then poll node data feedback instruction to acquire power and cumulative energy consumption of each phase LED lighting lamps and other power equipment;

[0079] In the polling process, if the node has no feedback data, execute data feedback instruction retransmission, and if the node still has no feedback data after 2 times of retransmission, mark the node communication fault;

[0080] Step 5: After the centralized controller completes polling of the network nodes of each phase power supply loop, calculate P i , P k , Q lamp , Q k , P lamp , Q sk , P sk , Q rest , ΔP rest at T k time by formula (6)-(14).

[0081] Step 6: Obtain S according to equation (15) k And in S k When = 1, P is calculated using equation (16). qk .

[0082] To achieve the timed synchronous collection of power data such as energy consumption from numerous electrical devices in urban lighting systems, LoRa network monitoring nodes receive T signals broadcast by the central controller. i The command to collect and save power data at any time is in T. i It continuously collects power and cumulative energy consumption data and stores the data in the storage unit group; if it receives a data feedback command from the central controller, it reads the power data stored in the storage unit group and wirelessly transmits the data to the central controller.

[0083] The software flowchart for the energy consumption and electricity theft monitoring method implemented by the LoRa network monitoring node is attached. Figure 3 The CPU's internal functional modules, such as SPI, UART, I / O, and timers, as well as the LoRa wireless communication module, are initialized. The communication module is set to receive mode, and the communication parameters are consistent with those of the central controller. A routine intelligent control program is run continuously to realize wireless control functions for LED lighting fixtures, such as wireless dimming and switching control. A polling method is used to determine if the communication module is receiving data, i.e., checking the level of the CPU pin PD2. If data is received (PD2 is high), the CPU sets the communication module's PD2 to low via SPI communication and reads the received instruction data. The instruction ID code is identified; if the instruction is for this device, the corresponding function program is executed based on the function code. If it is T... i If the power acquisition and storage function code is obtained, the internal system clock t is read, and Δt is calculated according to equation (5). c Start the timer to perform Δt c Timer interrupt, read T in the timer interrupt service routine i The system continuously collects power data such as voltage, current, power, and cumulative energy consumption of the electrical equipment and saves it to a designated storage unit group. If it is a data feedback function code, the communication module switches to transmission mode and sends the T data saved in the designated storage unit group. i The power data is sent to the central controller in real time, and after the transmission is completed, the communication module switches to receiving mode.
