[0036] The intelligent fusion terminal further comprises an event reporting module, which is used for reporting the lighting loop fault, control abnormality, line loss abnormality and energy use out-of-tolerance alarm event to a remote host platform in real time through a remote communication unit (4G / 5G / optical fiber Ethernet) thereof.

[0038] The hardware interface of the intelligent fusion terminal comprises 6 relay outputs, 3 RS-485 interfaces, 1 Ethernet interface and 1 power line carrier communication module interface, and the main control CPU has a frequency of not less than 400 MHz.

[0039] In one embodiment, the total length of the railway tunnel is 8 kilometers, and there are totally 8 transformer areas. Taking a railway tunnel with a length of about 1 kilometer as an example, one box transformer is arranged in the tunnel, and one intelligent fusion terminal of the embodiment is arranged in the box transformer as a central control unit. The terminal controls 6 lighting loops. The main control CPU is of a T536 type, and the relay is of an ADW1212HLW type. The hardware connection diagram of the tunnel lighting system is as shown in Figure 4As shown, the 6-way relay output of the terminal is connected to the lighting distribution cabinet. Its 1-way Ethernet port accesses the tunnel industrial switch, and communicates with the inlet / outlet manual start-stop control unit and the remote master station platform. Its 1-way PLC carrier module accesses the power line, and communicates with the train fault detection unit and the manual emergency start unit arranged along the line. Its 2-way RS-485 interfaces are connected to the manual emergency start unit (for reporting) and the maintenance double control unit respectively. The data flow is as follows:

[0040] 1. Control flow: the inlet manual start-stop unit presses the "light on" key, and through MQTT broadcast, the terminal receives and closes all 6-way relays.

[0041] 2. Acquisition flow: the built-in acquisition task of the terminal has a period of 1 minute, freezes and stores the U (voltage), I (current), P (power), and E (electric quantity) data of each loop.

[0042] 3. Analysis flow: the terminal calculates the difference between the total incoming line electric quantity and the sum of the electric quantities of the 6 loops every day to obtain the daily line loss rate. If the daily line loss rate suddenly jumps from the normal range (such as <5%) to 15%, the terminal immediately generates a "line loss anomaly" event and reports to the master station.

[0043] 4. Diagnosis flow: after receiving the alarm, the master station platform reviews the minute-level load curve of each loop of the tunnel. It is found that the current of loop 3 is continuously 0 during the alarm period, and the control state is "on". The platform can preliminarily diagnose "loop 3 control failure or lamp failure along the line", and automatically generate a work order to assign an operation and maintenance personnel to check on site.

[0044] The embodiment of the utility model upgrades the traditional "lighting control" to "intelligent lighting energy management system", realizing safe, energy-saving, efficient and intelligent tunnel operation.

[0045] The intelligent tunnel lighting fusion terminal system provided by the utility model takes the intelligent fusion terminal meeting the relevant technical specifications of State Grid (such as "General Technical Specification for Intelligent Fusion Terminal") as the central control unit of the tunnel lighting system. The terminal not only undertakes the traditional control instruction receiving and executing function, but more importantly, uses the built-in high-frequency data acquisition (HPLC deep application), minute-level acquisition, and senior function modules such as feeder line loss analysis to conduct panoramic electrical quantity monitoring on each lighting loop, specifically as follows:

[0046] 1. Hardware and interface multiplexing: the terminal itself has multiple RS-485, Ethernet, and power line carrier (PLC) interfaces, which can seamlessly access existing manual emergency start units (through PLC / RS-485), train detection units (through PLC), manual start-stop units (through Ethernet / MQTT), and other devices of the tunnel lighting, and multiplex their communication and control capabilities.

[0047] 2. High-frequency acquisition empowerment: The terminal acquires real-time voltage, current, power, and electricity data of each lighting loop through its AC analog acquisition function, and stores them at a minute freezing or even higher frequency. This enables the system to draw a fine load curve for each loop. "Frozen data" refers to the "freezing" in the meter reading terminology, which means acquiring and latching metering data at a specific time point (such as the whole minute) to ensure the consistency of the data time scale, facilitating subsequent period comparison and statistical analysis.

[0048] 3. Intelligent analysis and diagnosis:

[0049] (1) Line loss analysis: The entire tunnel lighting system is virtually a "district", the total incoming line is a "total meter", and each lighting loop is a "house meter". Using the terminal's district line loss analysis function, the theoretical line loss is automatically calculated, and abnormal energy loss caused by line aging, poor contact, and abnormal power consumption is found in real time.

[0050] (2) Event monitoring: Using the terminal's state quantity acquisition function, compare the relay control command with the actual feedback state, and report control loop breakage and other faults in time. Using the energy over-limit event monitoring function, alarm for abnormal power consumption in the loop.

[0051] (3) Fault early warning: Through trend analysis of minute-level current and power data, potential faults such as lamp life attenuation and line overload can be early warned.

[0052] (4) Unified management platform: All collected data, events, and control logs are uploaded to the master station platform through the terminal's remote communication interface (4G / 5G / optical fiber), realizing remote centralized monitoring, energy efficiency report, and intelligent strategy issuing (such as light adjustment according to traffic flow).

[0053] Compared with the prior art, the utility model has the following remarkable advantages:

[0054] 1. Control and metering depth fusion: Lighting loop control and high-precision energy metering are realized on one device, simplifying the system structure and reducing construction and maintenance costs.

[0055] 2. Energy consumption transparency and fine management: Provide minute-level power consumption data to make tunnel lighting energy consumption measurable, analyzable, and optimizable, providing accurate data support for energy efficiency analysis and energy-saving optimization strategy formulation.

[0056] 3. Intelligent and proactive operation and maintenance: Through line loss analysis, event proactive reporting, and energy anomaly diagnosis, passive inspection is changed to proactive warning, greatly improving operation and maintenance efficiency and fault handling speed.

[0057] 4. High reliability and scalability: based on a mature intelligent fusion terminal hardware platform, high reliability. Through containerized application management, new business APPs (such as environmental sensing access, video analysis linkage, etc.) can be flexibly expanded.

[0058] 5. Compliance with standards and forward-looking: the terminal complies with the power industry standard, and its high-frequency acquisition, HPLC deepening application, etc. lay a communication and data foundation for future access to a wider Internet of Things sensors (such as brightness sensors, vehicle flow detectors).

[0059] The above is a further detailed description of the utility model made in combination with specific preferred embodiments, and cannot be considered as limiting the specific implementation of the utility model to these descriptions. For those skilled in the art to which the utility model belongs, without departing from the concept of the utility model, a number of equivalent substitutions or obvious modifications can be made, and the performance or use is the same, which should be considered as belonging to the protection scope of the utility model.
