[0030] Example 1
[0031] A multifunctional intelligent lighting monitoring system includes a control terminal 2, a remote master station monitoring platform 1 and a single lamp controller 3; each first current branch and second current branch is installed with a circuit breaker 8, an AC contactor 6 and a current transformer 5, a plurality of lamps 9 are installed on the first current branch, and a plurality of electrical equipment 10 are installed on the second current branch; the circuit breaker 8 is equivalent to a manual switch, which is convenient for manually shutting off the corresponding current circuit during maintenance, and the current transformer 5 detects the current size in each current branch so as to feedback to the control terminal 2 when the current is abnormal, and promptly controls the AC contactor 6 to disconnect through the control module 24.
[0032] The control terminal 2 includes a processor, a 4G / 5G communication module 22, a LoRa communication module 23, a control module 24, a light sensing module 40, a routing module 42, a system clock 43, a metering module 55, a clock battery 53, a USB interface 54, an RS-485 module 25, a switch button 26, and a switching power supply 41 that are communicatively connected to the processor. The control terminal 2 is communicatively connected to the remote master station monitoring platform 1 through the 4G / 5G communication module 22; the light intensity of the lamp 9 is controlled through the light sensing module 40; the time is fed back to the processor through the system clock 43; the processor is powered by the switching power supply 41, and the clock battery 53 continues to power the processor after the external power supply is disconnected.
[0033] The control terminal 2 mainly monitors and measures the voltage, current and power consumption of the three-phase current main circuit 4; monitors and controls the output current of multiple first current branches and second current branches in real time. The control terminal 2 is connected to the three-phase current main circuit 4, multiple first current branches and multiple second current branches. The control terminal 2 is powered by a three-phase four-wire 220V AC voltage and samples the voltage. In fact, a main current transformer is also connected to the three-phase current main circuit 4 to convert the large current (0-200A) into a small current (0-6A), and then connected to the current sampling circuit of the control terminal 2. A dedicated metering module 55 is used inside the control terminal 2 to process and transform the connected voltage and current sampling signals, and finally form voltage, current, power, power factor, electric energy and other data. The processor in the control terminal 2 further analyzes, calculates, stores and transmits these data. At the same time, the control terminal 2 automatically calculates the sunrise and sunset times of each day according to the longitude, latitude and current date of the installation location, and then independently executes different control strategies for each first current branch in combination with the control parameters issued by the remote master station monitoring platform 1 (for example, in what time period to control the switch of the lamp 9 of which current branch and the light intensity, etc.), including all-night lights, midnight lights, time-period lights, cleaning lights, special lights and other lighting modes, and selects appropriate control strategies according to the different application scenarios of each first current branch, thereby realizing precise control of the lighting scene end.
[0034] The control module 24 is communicatively connected with the AC contactor 6; the control module 24 can output passive normally open contacts to control the AC contactors 6 of the first current branch and multiple second current branches. A through-type three-phase current transformer 5 is installed on each current branch. The secondary side of the current transformer 5 is connected to the terminal branch current sampling terminal. The metering module 55 samples and processes the current signal to form current data for each branch. The control terminal 2 determines the actual working conditions of the corresponding current branch and the corresponding phase (A, B, and C phases) according to the real-time current data of each current branch. If an abnormality is found, the corresponding control strategy is executed immediately and reported to the remote master station monitoring platform 1, truly achieving closed-loop control.
[0035] The control terminal 2 is connected to a temperature sensor and a fire extinguisher through the RS-485 module 25. The temperature sensor is wound around the output wires of the first current branch and the second current branch to realize dual temperature monitoring of the first current branch and the second current branch. When the control terminal 2 detects that the line temperature reaches 170°C, it is determined to be an abnormal temperature. The control module 24 in the control terminal 2 will first cut off the AC contactor 6 of the corresponding current branch at the first time to cut off the current output, and will give a start signal to the fire extinguisher through the RS-485 module 25 to realize the aerosol generator and the coolant to participate in the fire extinguishing together. And immediately report the event to the remote master station monitoring platform 1.
[0036] The control terminal 2 is connected to the single lamp controller 3 through the LoRa communication module 23, and the single lamp controller 3 is connected to each first current branch and each second current branch. The control terminal 2 communicates with the single lamp controller 3 using the LoRa network mode, and the spectrum is 465MHz-475MHz. The control terminal 2 sends the corresponding dimming instruction to the single lamp controller 3 according to the time period, and the single lamp controller 3 controls the corresponding lamp 9 to dim. According to the application of the LoRa network, it is divided into a large network and a small network. Although the large network has a wide network coverage area and a longer communication distance, it requires operators to build a basic network, and the cost of network construction is relatively high. Therefore, the communication mode of the LoRa small network is used in this embodiment, that is, the lamp 9 centrally controls the LoRa communication module 23 to act as a gateway, and the single lamp controller 3 constitutes a network node, but the communication distance of this mode is relatively short, generally about 500 meters. However, the radius of the cabinet door branch of ordinary lamps 9 is 800-1000 meters, which causes some lamps 9 that are farther away to be out of the LoRa network coverage of the concentrator. Therefore, it is necessary to set a routing module 42 in the control terminal to form a routing function. According to the distribution characteristics of street lamps, the wireless network composed of street lamp controllers is generally distributed linearly. The design comprehensively considers the GPSR routing algorithm and the MERR routing algorithm. In the implementation of the wireless routing solution of a single lamp linear network, a routing algorithm with one or more adjacent lamp nodes is proposed, which not only avoids the delay problem of single-hop communication between adjacent lamp nodes, but also maximizes the robustness and reliability of this linear communication network.
