Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel control, and in particular relates to a comprehensive management method and system for highway tunnel control configuration. Background Art

[0002] In the high-speed tunnel weak current control industry, there are generally several tunnels of varying lengths on a single highway, and the relevant equipment in these tunnels needs to be controlled. The scale and structure of the common PLC controllers in tunnels are as follows: Figure 1 shown.

[0003] The general tunnel control configuration method is to configure all controllers independently. The devices to be controlled in each controller are different, so it is necessary to write an independent configuration program for each controller, which includes the control of downstream devices, the collection of feedback signals, logical operations, etc. The signal data flow and configuration distribution are as follows: Figure 2 shown.

[0004] The configuration of the tunnel can be decomposed into three main parts: logic control configuration, command control configuration, and data acquisition configuration. The logic control configuration is used to receive instructions issued by the upper platform, and after internal calculations in the controller, it outputs a signal to the terminal device for execution; the command control configuration processes the signal output by the logic control configuration to the terminal device into an actual electrical signal and outputs it to the terminal device; the data acquisition configuration collects and processes the signals transmitted from the field to the controller. The simplified configuration diagram is as follows Figure 3 shown.

[0005] from Figure 3 It can be seen that the logic control configuration is the main component in the configuration of each controller in the tunnel, and the corresponding program editing is large. At the same time, due to the different locations of each controller, the number and type of terminal devices connected are also different. Therefore, the configuration programs running in each controller need to be written one by one, and the workload is large. For several tunnels on a single high-speed project, all controllers need to be configured with logic control one by one, which is a large workload and difficult to upload data. The data uploaded for each tunnel needs to be sorted one by one, which is not uniform.

[0006] The main disadvantage of this process configuration method is that for several tunnels on the same highway, the configuration is not reusable and all controllers need to be configured separately. The configuration workload is large and the program cannot be reused. The more tunnels there are on the same highway, the longer the configuration time caused by this problem. Summary of the invention

[0007] The purpose of the present invention is to provide a comprehensive management method and system for highway tunnel control configuration, which saves the workload of logical control configuration in the regional controller and makes the logical control configuration running in all substation main PLCs on the entire highway the same, greatly reducing the configuration difficulty, reducing the workload, and improving the work efficiency of high-speed tunnel implementation.

Based on the UCP protocol, the logic operation output result of the main PLC is transmitted to the regional controller through the inter-station reference variable, so that the regional controller can directly parse the logic operation output result, thereby improving the efficiency of data processing in the regional controller.

[0045] The following is a further detailed description of a comprehensive management method and system for highway tunnel control configuration proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0046] Embodiment 1

[0047] This embodiment aims at the existing configuration control mode of highway tunnels. For several tunnels on a single highway project, all controllers need to perform logic control configuration one by one, which is a large workload and difficult to upload data. The data uploaded for each tunnel needs to be sorted one by one, which is not uniform. A comprehensive management method for highway tunnel control configuration is provided. Based on the following inventive concepts, modularization, data interface and reusability of single tunnel configuration are achieved:

[0048] (1) The data flow in a single tunnel is aggregated to the substation PLC for uploading. Therefore, the substation PLC theoretically aggregates the data of all controllers in the tunnel, so the logic control configuration can be centralized in the substation PLC;

[0049] (2) The types of equipment in several tunnels along the entire highway are similar, and the differences in the number of equipment can be achieved through exhaustive method, that is, the logical control configuration is established in the substation PLC according to the maximum number of each type of equipment, and the configuration is universal for all tunnels along the entire highway;

[0050] (3) Based on the custom array function, corresponding custom arrays (variables) can be established one by one for the devices in the overall substation PLC logic control configuration, so that the logic control configuration can be independently operated in the substation PLC in conjunction with the custom point group;

[0051] (4) Based on the inter-station communication function of the UCP protocol, controllers can reference variables to each other. Therefore, the logic control configuration calculated in the substation main controller can pass the calculation results to the regional controller corresponding to the terminal device through the inter-station reference variables, and the command control configuration in the regional controller outputs the execution results.

[0052] Please see Figure 4 The integrated management method of the highway tunnel control configuration comprises the following steps:

[0053] S1: Obtain the number of terminal devices in each tunnel on the highway, and establish a corresponding first custom array in the main PLC of the substation of each tunnel according to the maximum number of each terminal device; the first custom array is used to define the number and data type of terminal device variables;

[0054] S2: Use the first custom array to perform logic control configuration on the terminal device in the tunnel;

[0055] S3: establishing a second custom array in each regional controller communicating with the main PLC; the second custom array is used to define the number and data type of terminal device variables within the control range of each regional controller, and the second custom array has a unique correspondence with some terminal devices in the first custom array;

[0056] S4: storing the terminal device data collected by the regional controller in the second custom array, and forwarding it to the corresponding variable of the first custom array;

[0057] S5: The logic operation output result of the main PLC is transferred to the corresponding variable of the second custom array of the regional controller through the inter-station reference variable, and the command control configuration in the regional controller outputs the execution result; the main PLC centrally completes the logic control function, and the regional controller completes the data collection and command execution of the terminal device.

[0058] Specifically, the following are mentioned in this embodiment:

[0059] Controller (Master PLC): An embedded device capable of running a control logic program.

[0060] Configuration: A program that runs in the controller, processes data, and controls the equipment in the tunnel to perform related logical actions.

[0061] Custom array (point group): A variable group with custom quantity and data type in the controller.

[0062] Please see Figure 5 First, the number of terminal devices in each tunnel on the highway is counted, and the corresponding first custom array A1B1 is established one by one in the main PLC of the substation according to the maximum number of each device.

[0063] Secondly, the first custom array A1B1 is used to configure the logic control of all terminal devices. Since the custom array is completely built in the main PLC of the substation and belongs to an independent variable in the main PLC, the logic control configuration can run independently. The operation logic is: when the instruction is received, the calculation is performed according to the data acquisition array A1, and the result output is stored in B1, and the logic ends.

[0064] Since the first custom array A1B1 established corresponds to the maximum number of various terminal devices in the tunnel, there must be any regional controller that can establish a second custom array A2B2 for the terminal device it controls, so that it has a unique correspondence with the custom array of some terminal devices in A1B1 in the main PLC. In this way, the correspondence between the second custom array A2B2 in the regional controller and the first custom array A1B1 in the main control PLC is established. By using the inter-station communication function of the UCP protocol, the terminal device data collected in the regional controller is stored in A2 and forwarded to the corresponding variable in the custom array A1 of the main control PLC; the logic operation output result B1 in the main controller PLC is passed to the corresponding variable in the custom array B2 of the regional controller through inter-station reference, so that the regional controller completes data collection and instruction execution, but the logic control function is completed centrally in the main control PLC.

[0065] Tunnel configuration modularization, data interface reuse method, see Figure 6 . It can be seen from the above embodiments that the configuration of the entire tunnel is integrated from the original configuration that is highly independent and not unified into a unified logic control configuration and a custom array A1B1 that can be run in any tunnel master controller. At this time, for any tunnel, the part that needs independent configuration is reduced to the data acquisition configuration and command control configuration in the master PLC, and the data acquisition configuration and command control configuration in the regional controller. The function of the regional controller is weakened, and it only performs the function of data transmission.

[0066] Therefore, the comprehensive management method of the highway tunnel control configuration in this embodiment is adopted. Through cross-station communication and equipment planning, an overall configuration for all controllers in the tunnel is established, so that the configuration can be applied to all tunnel groups on the highway, thereby simplifying the workload of design configuration and improving work efficiency.

[0067] Among them, the substation main PLC performs logical control configuration on the terminal equipment in the tunnel further including:

[0068] In the logic control configuration, the logical actions of the terminal equipment in the tunnel are described, the instructions sent by the host computer are received, and the execution signal is output to the regional controller after the main PLC operation, so that the terminal equipment in the regional controller executes the relevant logical actions. Specifically include:

[0069] Logical control is performed on the display of lane control lights and traffic lights in the tunnel. It is not allowed for the same lane control light to be green arrows on both sides at the same time, and traffic lights are not allowed to display contradictory states.

[0070] Logically control the lights in the tunnel to achieve lighting and energy saving;

[0071] Logically control the fans in the tunnel to ensure the air quality in the tunnel.

[0072] For example, lane control lights and traffic lights are controlled. Lane control lights are set at the entrance, exit and every 250 to 300 meters in the tunnel to indicate the status of each lane. The lane control lights use LED display mode, and the display board can display red "×" or green "↑", indicating that the lane is closed or open. The control status of the lane control lights includes: open, reverse and no-entry. In order to allow drivers trapped in the tunnel to safely exit the tunnel and change the one-way tunnel into two-way driving in an emergency, the lane control lights use a double-sided display method. Traffic lights are set at the entrance of the tunnel to indicate the traffic situation in the tunnel at this time. Traffic lights have three states: red, green and yellow. Green means that the traffic in the tunnel is normal, yellow means that the traffic is abnormal and you should drive carefully, and red means that the tunnel is closed at this time and no passage is allowed.

[0073] The lane control lights and traffic lights can also be logically interlocked, that is, the same lane control light is not allowed to be green arrows on both sides at the same time, and the traffic lights are not allowed to display contradictory states, such as red and green cannot be displayed at the same time. The locking logic of the lane control lights is as follows: for the indicator lights LS-1 and LS-2 on the front and back sides of the same lane, when LS-1 needs to be changed to a green arrow, first determine whether LS-2 is a green arrow, if not, execute LS-1 switching; if LS-2 is a green arrow, a signal of logical conflict operation failure is issued, LS-1 switching is prohibited, and LS-1 is forced to display a red cross.

[0074] The number of lighting lamps to be put into use is determined by comparing the data detected by brightness detection equipment (including brightness detectors outside the cave and illuminance detectors inside the cave), thereby achieving the dual goals of normal lighting and energy saving.

[0075] The data detected by environmental monitoring equipment (mainly carbon monoxide concentration detectors, dust concentration detectors and wind direction and speed detectors) is used as the basis for judging the air quality status of the tunnel. The status of the fan is adjusted according to the pre-set threshold to ensure the air quality in the tunnel.

[0076] The high-speed tunnel control configuration is a program used to control ventilation, lighting, traffic signs and other equipment in the high-speed tunnel. This configuration runs in the on-site controller, which can pass the on-site data to the upper platform for data processing. It also accepts the instructions of the upper platform and outputs the corresponding control signals after processing to control the on-site equipment to perform corresponding actions. The area controllers in the tunnel are equidistantly distributed in the tunnel, and the hard redundant master PLC is located in the tunnel entrance and exit substations. The high-speed tunnel control configuration runs in the area controller and the redundant master PLC to collect signals, monitor status, and control output of the on-site equipment.

[0077] The comprehensive management method of the highway tunnel control configuration in this embodiment can form an overall configuration for all controllers in the tunnel through unique cross-station communication and equipment planning, so that the configuration can be applied to all tunnel groups with common characteristics, thereby simplifying the workload of design configuration and improving work efficiency. That is, the planning of the maximum number of devices in the entire highway tunnel group, the corresponding relationship between the custom arrays A1B1 and A2B2, and the integrity of the logical control configuration running in the main PLC of the substation.

[0078] Embodiment 2

[0079] This embodiment provides a comprehensive management system for highway tunnel control configuration. Figure 7 The system comprises:

[0080] The main control module 1 is used to obtain the number of terminal devices in each tunnel on the highway, and to establish a corresponding first custom array in the main PLC of the substation of each tunnel according to the maximum number of each terminal device; the first custom array is used to define the number and data type of the terminal device variables;
