[0033] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The embodiment of the present invention discloses an intelligent monitoring system for emergency lighting devices in high-altitude railway tunnels. As Figure 1 shown, it mainly includes a main controller, an intelligent monitoring device, and an emergency lighting distribution box. The intelligent monitoring device is installed adjacent to the main control box and the emergency lighting distribution box. The main controller is connected to the main station of the tunnel monitoring system through a network cable or optical fiber, and adopts the standard Modbus TCP communication protocol to realize two-way data transmission with the main station of the monitoring system. At the same time, the main controller is connected to the emergency lighting distribution box through a control cable to control the on and off of each emergency lighting branch lamp. The main controller is connected to the intelligent monitoring device through a network cable, and the communication protocol adopts the standard Modbus TCP to realize two-way data transmission between the main controller and the intelligent monitoring device.

[0035] Specifically, the power lines of each emergency lighting branch come out of the emergency lighting distribution box and are connected to the intelligent monitoring device. The power lines of each emergency lighting branch come out of the intelligent monitoring device and are connected to the on-site emergency lighting lamps. The power lines of each emergency lighting branch "pass through" the intelligent monitoring device. The intelligent monitoring device can collect signals such as voltage, current, and power of the power circuit, and then process, track, analyze, and discriminate the signals, and upload the results to the main controller in the form of communication. The main controller uploads the received data to the main station of the tunnel monitoring system in the form of communication, and at the same time receives the control signal from the main station of the tunnel monitoring system, and together with the emergency lighting control box, realizes the remote control of the emergency lighting lamps.

[0036] As Figure 2 shown, the main controller includes a PLC, an intermediate relay group, and a first touch screen. The PLC integrates network interface 1, network interface 2, a digital quantity output module, and a digital quantity input module.

[0037] Specifically, the network interface 1 is used to communicate with the main station of the tunnel monitoring system and the intelligent monitoring device to achieve data sharing. The network interface 2 communicates with the first touch screen to implement the human-machine interaction function on the main controller side. The touch screen is used to display the status of the lamps or emergency lighting branches, and at the same time, it can be operated on the touch screen to achieve on-site control of the on and off of the emergency lighting branch lamps. The digital quantity output module is connected to the coils of the intermediate relay group, and the auxiliary contacts of the relay are connected to the emergency lighting distribution box. The PLC controls the intermediate relay group through the digital quantity output module, and the intermediate relay group controls the emergency lighting distribution box to achieve the on and off of the power circuits of the emergency lighting branch lamps, thereby realizing the on and off control of the emergency lighting branch lamps. The emergency lighting distribution box feeds back the on and off status of the power circuits of each emergency lighting branch to the digital quantity input module through the monitoring cable.

[0038] As Figure 3 shown, the intelligent monitoring device consists of a power module, a processor ESP32, a second touch screen, a network interface chip CH9121, and a single-phase six-way mutual inductance type power metering module IM1259G.

[0039] Specifically, the power module is respectively connected to the processor ESP32, the second touch screen, the network interface chip CH9121, and the single-phase six-way mutual inductance type power metering module IM1259G, and is used to provide the power required for the operation of each module in the device, including 5V and 3.3V.

[0040] The single-phase six-way mutual inductance type power metering module IM1259G is connected to the processor ESP32 through the RS485 communication interface, and is used to collect information such as the working current, voltage, and power of the single-branch lighting lamps, and transmit the collected data such as the voltage, current, and power of the emergency lighting circuit lamps to the processor ESP32 in accordance with the standard Modbus RTU communication protocol.

[0041] In this embodiment, the single-phase six-way mutual inductance type power metering module IM1259G can collect 6-way AC parameters, including multiple electrical parameters such as voltage, current, power, power factor, frequency, and electric energy; it has 1-way RS-485 communication interface, and the communication protocol uses the standard Modbus-RTU, with good compatibility and convenient programming; it has an RS-485 communication interface with an ESD protection circuit; the wide working voltage is AC80~265V; it can be optionally equipped with different specifications of single-turn through-hole PCB fixed or split-core current transformers, which are convenient to use.

[0042] The processor ESP32 is used to analyze, discriminate, give early warnings, and give alarms for the received lighting lamp information.

[0043] The network interface chip CH9121 is connected to the processor ESP32 through a serial port, supports the standard Modbus TCP or MQTT protocol, and can implement functions such as remote control, telemetry, remote adjustment, and remote signaling.

[0044] The second touch screen is connected to the processor ESP32 through a serial port, which is used to realize the human-computer interaction function on one side of the intelligent monitoring device, and realize the display of status and data, and the adjustment and setting of parameters.

[0045] The emergency lighting distribution box is mainly composed of circuit breakers and contactors for each emergency lighting branch, and realizes the on-off control of the lighting fixtures for each emergency lighting branch.

[0046] It should be noted that the software programs used by the intelligent monitoring system for railway tunnel disaster prevention and rescue emergency lighting devices to realize corresponding functions in this embodiment are all existing, and only need to be simply integrated and changed by those skilled in the art according to the actual situation.

[0047] In this embodiment, the intelligent monitoring device monitors the data of the lighting fixtures for each emergency lighting branch. Compared with the solution of monitoring each lighting fixture, it effectively reduces the construction cost, reduces the failure rate, improves the operation stability of the system, and further improves the informatization and intelligence level of the relevant equipment and facilities for tunnel emergency lighting.

[0048] In this embodiment, the intelligent monitoring device is used to collect data such as loop working current, voltage, power, power factor, and electric energy in real time, automatically correct the normal working current of the branch, alarm for the upper and lower limits of voltage, current, and three-phase imbalance, and can calibrate the alarm threshold, with a threshold alarm function accurate to ±5%.

[0049] At the same time, the intelligent monitoring device also provides alarms for lamp damage information, lighting circuit fault information, and whether the device is offline. According to the energy consumption of the lamp, that is, the working current and the illuminance of the lamp, and the fact that the temperature, that is, the heat energy generated by the lamp beads and the circuit, has a constant relationship. If the relationship deviates, it is determined that the lamp has a potential risk of failure. The single deviation value is the factory-set value. The device discriminates the health status of the lamp equipment by tracking the real-time working current parameters to realize the equipment health early warning function.

[0050] In addition, the intelligent monitoring device has the function of information communication with the remote control platform, and has functions such as remotely reading real-time data, real-time status, historical data, fault alarms, and early warnings. Through the deployment of the main device, the demand for the processing and computing power of the hardware equipment of the remote control platform can be effectively reduced, the network bandwidth demand can be reduced, and the construction scale of the central platform can be reduced.

[0051] The complete working process of this embodiment is as follows:

[0052] When the main controller, intelligent monitoring device and emergency lighting distribution box are used in combination, the intelligent monitoring device collects data such as loop working current, voltage, power, power factor, and electric energy in real time, analyzes, discriminates, alarms and automatically tracks and calibrates the standard values for the acquired data, and displays them on the touch screen. At the same time, the network interface chip provides a standard protocol interface for the main controller to read the result information, and the main controller writes the read result information to the main station of the tunnel monitoring system through the network interface.

[0053] When the main controller reads the instructions from the main station of the tunnel monitoring system through the network interface, it drives the corresponding relay by controlling the digital quantity output module, and the auxiliary contact of the relay controls the emergency lighting distribution box to realize the control function of the emergency lighting branch. During this period, the digital quantity input module is used to collect the working state information of the emergency lighting branch, such as switch state, remote / local state, etc., and writes it to the main station of the tunnel monitoring system through the network interface.
