In the past, how to balance the safety and energy conservation of tunnel illumination, reduce energy consumption and reduce the tunnel operation cost becomes a difficult problem to be solved by tunnel design, construction and operation units.

Although the measures have the effect of energy conservation to a certain extent, the phenomenon of electric energy waste still exists in the actual operation, and the problems of contradiction between the running safety and the tunnel monitoring are generated in the operation process, and the like.

For the research of the safety and energy-saving technology of the road tunnel lighting system, the research, development and application of the tunnel lighting technology are actively explored and practiced by transportation departments and tunnel scientific research workers, and improvement measures are tried to be taken in the aspects of tunnel lighting design standards, tunnel lighting control methods, tunnel lamp use, lighting system power supply modes, tunnel monitoring operation and maintenance management and the like, so that the tunnel lighting quality is improved, and the energy consumption and the operation cost of the tunnel lighting system are reduced.

First, referring to fig. 1, fig. 1 shows a schematic structural diagram of a tunnel lighting control system provided in the present application, which mainly includes a tunnel lighting centralized controller, a terminal dimming controller, a node controller, an out-of-hole light intensity detector, and an in-hole light intensity detector, and of course, communication devices may be involved between these components to provide a communication environment required for communication between the components.

In the components, the tunnel illumination centralized controller is respectively connected with the terminal dimming controller, the light intensity detector outside the tunnel and the light intensity detector inside the tunnel; the terminal dimming controller is connected with the node controller, and the node controller is connected with the lighting lamps (which can be LED lamps) in the deployment area of the tunnel lighting control system.

It can be understood that the terminal dimming controller and the node controller are configured in a multi-level architecture for better controlling the lighting fixture, and the tunnel lighting centralized controller completes the work control of the lighting fixture through the two-level architecture of the terminal dimming controller and the node controller.

The tunnel lighting centralized controller-terminal dimming controller-node controller-lighting lamp four-level architecture is characterized in that the number of the tunnel lighting centralized controller at the top level of the architecture to the lighting lamps at the lowest level is increased step by step, and the number of the tunnel lighting centralized controller, the terminal dimming controller, the node controller and the lighting lamps is configured under the condition that the whole tunnel coverage lighting and the lighting lamp work control are met.

In the automatic and intelligent tunnel lighting control working process, the tunnel lighting integrated controller executes the processing of the control strategy and distributes control instructions, specifically, the method comprises two stages:

1. a lighting dimming instruction generation step, wherein a tunnel lighting integrated controller receives an outside-tunnel light intensity detection result acquired by an outside-tunnel light intensity detector and an inside-tunnel light intensity detection result acquired by an inside-tunnel light intensity detector, and generates a corresponding lighting dimming instruction according to both the outside-tunnel light intensity detection result and the inside-tunnel light intensity detection result on the basis of a preset control strategy, wherein the preset control strategy comprises that the inside-tunnel light intensity and the outside-tunnel light intensity are positively correlated in a daytime period;

2. in the illumination dimming instruction distribution link, the tunnel illumination centralized controller transmits an illumination dimming instruction to the terminal dimming controller, the terminal dimming controller transmits the illumination dimming instruction to the node controller, and the node controller adjusts the illumination intensity of the illumination lamp according to the illumination dimming instruction.

It can be understood that, at the current in-process in the tunnel of time of daytime, if there is great difference in the illumination inside and outside the hole, no matter the vehicle gets into the tunnel, still leaves the tunnel, its people's eye of the driver on the vehicle all causes instantaneous "blindness" condition because of receiving the violent contrast of ambient light intensity easily, also consequently, this application starts with from the illumination light intensity of illumination lamps and lanterns in the tunnel, through the illumination light intensity of adjustment illumination lamps and lanterns for the difference between the inside and outside illumination light intensity in tunnel reduces, and then can slow down or even avoid the "blindness" condition that the driver appears.

On the basis, the tunnel illumination centralized controller also considers that different influences, especially real-time weather changes, such as sudden turning to the shade, sudden sunny days, heavy rain and other weather changes, can also obviously influence the light intensity outside the tunnel in a short time, and accordingly can adaptively adjust the light intensity inside the tunnel according to the real-time light intensity outside the tunnel on the basis of the light intensity detection result outside the tunnel acquired by the light intensity detector outside the tunnel in real time and the light intensity detection result inside the tunnel acquired by the light intensity detector inside the tunnel in real time, so that the light intensity inside the tunnel is positively correlated with the light intensity outside the tunnel, the difference between the illumination light intensity inside and outside the tunnel is reduced, and the blindness condition of a driver is accurately and effectively relieved or even avoided.

It can be understood that, under the condition that illumination covered in satisfying the tunnel, because the control strategy is predetermine of tunnel illumination centralized control ware configuration, include that light intensity is positive correlation with the outer light intensity of hole in the time quantum of daytime, consequently, can adjust the light intensity in the hole according to the outer light intensity suitability ground of hole of reality, avoid keeping the power consumptive problem that the hole light intensity of high strength caused to a certain extent, realize more intelligent light intensity regulation effect, promote higher electric energy utilization.

In addition, in order to further achieve a higher electric energy utilization rate, as an implementation manner suitable for practical use, the preset control strategy required for generating the lighting dimming instruction may specifically include that while the light intensity in the tunnel is positively correlated with the light intensity outside the tunnel in the daytime, the light intensity in each section from the first tunnel entrance to the second tunnel entrance is gradually reduced to a recovered state change;

the tunnel lighting centralized controller transmits the lighting dimming instruction of each section to the corresponding terminal dimming controller, the terminal dimming controller transmits the lighting dimming instruction to the node controller of the corresponding section, and the node controller adjusts the lighting intensity of the lighting lamp of the corresponding section according to the lighting dimming instruction.

Obviously, under the setting, the lighting intensity of the whole lighting lamp can be controlled in a stepless dimming mode from the whole, different adjusting ranges can be presented for the lighting lamps in different sections, or the adjusted lighting intensity can be presented differently to achieve the lighting intensity of a plurality of lighting lamps, and the light intensity of each section from the first tunnel opening to the second tunnel opening is gradually reduced to be recovered and changed.

It will be appreciated that the "blindness" condition of the driver may occur at the entrance and exit, while the section of the tunnel remote from the entrance may be kept at a lower intensity, which further reduces power consumption while meeting the required intensity of the vehicle.

The setting of the high illumination light intensity at the two sides and the low illumination light intensity in the middle, the section or the division unit of adjusting step by step may be specifically the unit of tunnel length, number of illumination lamps and lanterns, and the like.

Furthermore, it should be understood that the above mentioned preset control strategy is directed to the daytime period, which can be understood as the illumination intensity existing outside the tunnel and outside the hole, that is, the colloquially understood time period marked off by the present application in the daytime.

The daytime period can be set manually or determined automatically by a machine.

In the above, for environmental factors such as different seasons, different geographical environments, and even different weather, different influences may be caused on the light intensity outside the tunnel, especially real-time weather changes, such as sudden turning to the shade, sudden sunny day, heavy rain, and the like, and may also cause a significant influence on the light intensity outside the tunnel in a short time.

Therefore, as another practical implementation manner, in the present application, the daytime period may be determined by the centralized tunnel illumination controller, and specifically, the daytime period referred to in the present application may be a period obtained by the centralized tunnel illumination controller determining the daytime starting time and the daytime ending time according to the detection result of the light intensity outside the tunnel continuously collected by the light intensity outside the tunnel detector.

Obviously, under the condition that the out-of-hole light intensity detector is originally configured, the tunnel illumination centralized controller can accurately determine the daytime time period which is considered to be possibly changed due to the environmental condition according to the out-of-hole light intensity detection result continuously collected by the tunnel illumination centralized controller.

Further, in terms of hardware except for lighting fixtures, the tunnel lighting centralized controller, the terminal dimming controller and the node controller can be understood as control equipment, the types of the equipment can be specifically the same or different, the light intensity detector outside the tunnel and the light intensity detector inside the tunnel can be understood as a light intensity sensor or a device including the light intensity sensor, and the light intensity sensor is a device capable of sensing the intensity of light and outputting the light.

It can be understood from the above that, the tunnel illumination control system deployed for the control center based on the tunnel illumination centralized controller controls the illumination intensity of the endmost illumination lamp around the illumination intensity inside and outside the hole, and in the actual working process, besides the control work of the illumination intensity of the illumination lamp, other works can be involved.

For example, the centralized tunnel lighting controller may configure an external interface, and based on the external interface, the centralized tunnel lighting controller may upload the operation information of the tunnel lighting control system to the segment-based central control room corresponding to the tunnel.

Therefore, the tunnel lighting centralized controller can count, analyze, monitor and store the working information related to the tunnel lighting control system, and output the working information to a third-party platform for user display. The third-party platform may be specifically a platform device outside a road segment sub-center control room corresponding to the tunnel, a user mobile phone, a computer and other tunnel lighting control systems.

On the other hand, the centralized tunnel lighting controller can also receive control over the system from the segment-based central control room, wherein the control can be automatic control from equipment or manual work from workers.

This means that the tunnel lighting control system can receive external control during the automatic control operation of the lighting intensity of the lighting fixture, so as to cope with special situations in practical application, and thus, the tunnel lighting control system can ensure the controllability of the tunnel lighting control system for the outside.

And secondly, the tunnel illumination integrated controller can also have a function of field automatic control, and under the conditions that equipment faults, communication faults and the like occur in the sub-center control room of the road section where the tunnel is maintained and tested, a field tunnel illumination control system can replace the sub-center control room to control, namely, the tunnel illumination integrated controller has the work processing capacity of the sub-center control room within a certain range through the data processing capacity of the sub-center control room and has a disaster recovery function.

In addition, a communication network in the tunnel lighting control system can specifically adopt a single-mode optical cable, that is, a communication network adopted among devices such as a tunnel lighting centralized controller, a terminal dimming controller, a node controller, an out-of-hole light intensity detector, an in-hole light intensity detector and the like can specifically be a wired communication network adopting the single-mode optical cable, each node in the network is connected through an optical fiber interface of an Ethernet switch to form an Ethernet single-mode optical fiber redundant ring structure, in the Ethernet single-mode optical fiber redundant ring structure, the network is a peer-to-peer network, the operation of a backbone network cannot be influenced by the fault of any node, any point on the ring network is broken by poking, and the communication transmission can still be normally carried out, so that the field bus can be ensured to be prevented from being interfered by the outside, the communication transmission is smooth, and the reliability of communication and data transmission is improved.

In the communication network in the tunnel illumination control system, colloquially, the centralized controller of tunnel illumination can understand the main website, through ethernet card, the data interchange is realized to the switch, terminal dimming controller can understand the slave station in the tunnel, terminal dimming controller is connected through the RS485 bus with the node controller, the node controller links to each other with the illumination lamps and lanterns, the centralized controller of tunnel illumination passes through the RS485 bus (or ethernet module) and constitutes local data network, in the design requirement, be connected between each subassembly of the centralized controller of tunnel illumination and system and have reliable electromagnetic isolation and interference killing feature.

Specifically, when the tunnel lighting centralized controller establishes communication with a sub-central control room of a road section where the tunnel is located, the involved transmission scheme may be: the Ethernet switch at the centralized controller for tunnel lighting is transmitted to the branch central control room of the road section where the tunnel is located through the single-mode optical fiber, and the communication speed is 10/100M.

Further, in terms of communication, the centralized tunnel lighting controller may be configured as an independently operating control system, in this case, in practical applications, different tunnels may be configured with different centralized tunnel lighting controllers, each tunnel may also be configured with a standby or multiple centralized tunnel lighting controllers, and multiple centralized tunnel lighting controllers may adopt a logical topology structure of a ring-type redundant optical fiber network with a standby channel, so that similar to the above-mentioned ethernet single-mode optical fiber redundant ring structure, the ring-type redundant optical fiber network has a strong anti-interference capability, and reliability of communication and data transmission between the centralized tunnel lighting controllers is ensured.

Further, returning to the aspect of controlling the lighting fixtures again, it can be understood that the lighting intensity of the lighting fixtures is controlled according to the lighting intensity inside and outside the hole, so that the closed-loop control of the lighting intensity inside the hole is already realized, and on the basis, in order to further deepen the effect of the closed-loop control and optimize a closed-loop circuit, variable conditions which may occur to different lighting fixtures at the tail end of the system in practical application can be continuously introduced, so that lighting dimming instructions which are more targeted and accord with the practical conditions of the lighting fixtures in different conditions are issued to the lighting fixtures in different conditions.

As another practical implementation manner, the node controller on the side of the lighting fixture may further collect working information of the lighting fixture, where the working information may specifically include information such as power information and state information, and at this time, the node controller transmits the working information to the terminal dimming controller, and the terminal dimming controller transmits the working information to the tunnel lighting centralized controller;

the tunnel illumination centralized controller generates a corresponding illumination dimming instruction according to the light intensity detection result outside the tunnel, the light intensity detection result inside the tunnel, the electric power information and the state information on the basis of a preset control strategy.

It can be understood that the power information reflects the power consumption condition of the lighting fixture, and the state information reflects the contents of the lighting fixture other than the power consumption condition, such as a fault state, an on-off state, the number of times of adjusting the lighting intensity, the rated power, and the like.

For example, if a failure occurs, there is no need to generate a lighting dimming command, or a lighting dimming command for temporarily cutting off the power supply thereof is generated; if the lighting lamp with low rated power exists, even if the low rated power cannot meet the requirement of the lighting intensity required to be adjusted currently, the output power adjusted by the lighting dimming instruction is not higher than the low rated power, so that the situations of overheating, unstable operation and the like of the lighting lamp are avoided; if a lighting fixture has a high power consumption condition, the lighting fixture itself or a related line thereof may have an abnormal condition, and within an allowable range, the output power adjusted by the lighting dimming command may also limit the output power.

Further, in response to the requirement of energy saving, if the tunnel is in an emergency, it may also be configured with a function to release the energy saving limitation for facilitating emergency traffic and lighting in the tunnel, so as to respond to the emergency of the tunnel, for example, a car accident, a car falling object, water leakage, an exposed wire, etc. in the tunnel, it is necessary to provide sufficient light support for the driver of the vehicle to see clearly the road condition ahead for danger avoiding operation.

In this case, a corresponding early warning signal may be configured, and correspondingly, the preset control strategy configured by the tunnel illumination integrated controller may further include adjusting the light intensity in the hole to the highest power output state when the tunnel illumination integrated controller receives the warning signal.

It can be understood that the alarm signal may be received by the tunnel lighting centralized controller from an external device, may be initiated by a button in the tunnel under manual operation, or may be automatically triggered by the tunnel lighting centralized controller according to monitoring of the state of the device in the tunnel, and may specifically be adjusted according to actual needs.

In order to further understand the tunnel lighting control system provided by the present application, on the basis of the above-mentioned related control functions, the control functions that can be realized by the tunnel lighting control system are listed in more detail in combination with the practical application requirements.
