[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention 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 evacuation indication devices in high-altitude railway tunnels, as Figure 1 shown, which mainly includes a main controller, an intelligent monitoring device, and an evacuation indication distribution box. The intelligent monitoring device is installed adjacent to the main control box and the evacuation indication 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 achieve two-way data transmission with the main station of the monitoring system. At the same time, the main controller is connected to the evacuation indication distribution box through a control cable to control the lighting and extinguishing of each evacuation indication branch light fixture. The main controller is connected to the intelligent monitoring device through a network cable, and the communication protocol adopts the standard Modbus TCP to achieve two-way data transmission between the main controller and the intelligent monitoring device.

[0035] Specifically, the power lines of each evacuation indication branch light fixture come out from the evacuation indication distribution box and are connected to the intelligent monitoring device. The power lines of each evacuation indication branch light fixture come out from the intelligent monitoring device and are connected to the on-site evacuation indication light fixtures. The power lines of each evacuation indication branch light fixture "pass through" the intelligent monitoring device, and the intelligent monitoring device can collect signals such as voltage, current, and power of the power branch, 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 of the main station of the tunnel monitoring system to achieve remote control of the evacuation indication light fixtures together with the evacuation indication control box.

[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 realize the human-computer interaction function on the main controller side. The touch screen is used to display the status of the lamps or evacuation indication branches, and at the same time, operations can be performed on the touch screen to achieve on-site control of the on and off of the lamps on the evacuation indication branches. 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 evacuation indication distribution box. The PLC controls the intermediate relay group through the digital quantity output module, and the intermediate relay group controls the evacuation indication distribution box to realize the on and off of the power supply of the lamps on each evacuation indication branch, thereby realizing the on and off control of the lamps on the evacuation indication branches. The evacuation indication distribution box feeds back the on and off status of the power supply of the power branches of the lamps on each evacuation indication branch to the digital quantity input module through the monitoring cable.

[0038] As Figure 3 shown, the intelligent monitoring device is composed 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 transmits the collected data such as voltage, current, and power of the lamps on the evacuation indication branches to the processor ESP32 in the standard Modbus RTU communication protocol. The processor ESP32 analyzes, discriminates, warns, and alarms the collected information of the lamps on the evacuation indication branches.

[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 adopts the standard Modbus-RTU, with good compatibility and convenient programming; the RS-485 communication interface with an ESD protection circuit; wide operating voltage AC80~265V; optional different specifications of single-turn through-hole PCB fixed or split-core current transformers, which are convenient to use.

[0042] The network interface chip CH9121 is connected to the processor ESP32 through the serial port, supports the standard Modbus TCP or MQTT protocol, and can realize functions such as remote control, remote measurement, remote adjustment, and remote signaling.

[0043] The second touch screen is connected to the processor ESP32 through a serial port, which is used to implement the human-computer interaction function on one side of the intelligent monitoring device, and realize the display of status and data, as well as the adjustment and setting of parameters.

[0044] The evacuation indication distribution box mainly consists of circuit breakers and contactors for each evacuation indication branch, and realizes the on-off control of the luminaires for each evacuation indication branch.

[0045] It should be noted that the software programs used to implement the corresponding functions in the intelligent monitoring system of the railway tunnel evacuation indication device in this embodiment are all existing, and only need to be simply integrated and modified by those skilled in the art according to the actual situation.

[0046] In this embodiment, for the data monitoring of the luminaires on each evacuation indication branch by the intelligent monitoring device, compared with the scheme of monitoring each luminaire, it effectively reduces the construction cost, reduces the failure rate, and improves the operation stability of the system.

[0047] The intelligent monitoring device can collect data such as the working current, voltage, power, power factor, and electric energy of the luminaires on each evacuation indication branch in real time, automatically correct the normal working current of the branch luminaires, give alarms for the upper and lower limits of voltage, current, and three-phase unbalance, and can calibrate the alarm threshold, with a threshold alarm function accurate to ±5%.

[0048] At the same time, the intelligent monitoring device can also give alarms on the luminaire damage information, evacuation indication branch fault information, and whether the device is offline. According to the energy consumption of the luminaire, that is, the working current and the illuminance of the luminaire, and the fact that the temperature, i.e., heat energy, generated by the lamp beads and the circuit has a constant relationship. If the relationship deviates, it is determined that the luminaire has a potential risk of failure. The single deviation value is the factory-set value. The device discriminates the health status of the luminaire equipment by tracking the real-time working current parameters to realize the equipment health early warning function.

[0049] In addition, the intelligent monitoring device has the information communication function 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. It can effectively reduce the demand for the processing and computing power of the hardware equipment of the remote control platform, reduce the network bandwidth demand, and reduce the construction scale of the central platform.

[0050] The complete working process of this embodiment is as follows:

[0051] The main controller, intelligent monitoring device and evacuation indication distribution box are used in combination. The intelligent monitoring device collects data such as the working current, voltage, power, power factor, and electric energy of each evacuation indication branch road lamp in real time, analyzes, discriminates, alarms and automatically tracks and calibrates the standard values for the obtained data, and displays them on the second 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.

[0052] 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 through the control digital quantity output module, and the auxiliary contact of the relay controls the evacuation indication distribution box to realize the control function of turning on and off each evacuation indication branch road lamp. During this period, the digital quantity input module is used to collect the working state information of the evacuation indication branch road lamp, such as the switch state, remote / local state, etc., and writes it to the main station of the tunnel monitoring system through the network interface.

[0053] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and reference can be made to the description of the method part for related parts.
