Description

Technical Field

[0001] The present invention relates to the technical field of urban underground integrated pipe gallery equipment management, and in particular to a function expansion system and method for an ACU controller. Background Art

[0002] The urban underground integrated pipe gallery is an integral part of urban construction. It includes power supply, water supply, gas supply, heating / cooling, drainage and various information pipelines. It is the foundation and guarantee for the survival and development of the city. It is the nerve and blood vessel that ensures the normal functioning of the city and the people's living and working in peace and contentment. The integrated pipe gallery is an important part of the urban underground pipeline integration. The area controller (ACU) control system can comprehensively analyze the various environmental data in the integrated pipe gallery and check whether the data is abnormal, so as to judge whether to open or close the fan or lighting system to achieve the purpose of ventilation, energy saving and emission reduction. While realizing real-time monitoring of the environmental conditions of the integrated pipe gallery, it can respond to abnormal situations in a timely manner to improve operational efficiency and safety management level.

[0003] With the continuous development of technology, various information pipelines in urban underground integrated pipe corridors will become more and more complex, so the ACU regional controller needs to install more sensors to fully obtain the complex environmental data in urban underground integrated pipe corridors. However, the current situation is that when functional expansion is required, the selected sensors and other equipment are simply installed in the ACU cabinet without any planning, which makes the space of the ACU cabinet unable to be effectively utilized. When the internal space of the ACU cabinet is full and new functions need to be met, if the ACU cabinet can no longer install sensors with corresponding functions, then either all the equipment in the ACU cabinet should be disassembled and re-planned and assembled to save equipment costs; or, regardless of the equipment cost, a larger ACU cabinet should be replaced, and all the equipment in the ACU cabinet should be disassembled and assembled in the new ACU cabinet. Both methods require downtime operation, which will incur additional time and labor costs. Summary of the invention

[0004] One of the purposes of the present invention is to provide a function expansion system for an ACU controller, which can reasonably plan the internal space of the ACU cabinet to facilitate low-cost and high-efficiency function expansion.

[0005] In order to achieve the above object, a function expansion system for an ACU controller is provided, including a server, wherein the server includes:

[0006] Data acquisition module: used to obtain the function expansion requirements of the ACU controller, obtain the size data of the ACU cabinet corresponding to the ACU controller, and obtain the model data and structural distribution data of each functional module of the ACU controller; the functional module is a hot-swappable module;

[0007] Requirements parsing module: used to select functional modules that meet the functional expansion requirements from the preset hardware database;

[0008] Model matching module: used to match the pre-installed device model of the corresponding functional module from the preset model database, and also used to match the cabinet model of the corresponding ACU cabinet from the preset model database according to the size data of the ACU cabinet, and match the corresponding installed device model from the preset model database according to the model data of each functional module of the ACU controller;

[0009] Space planning module: used to assemble models according to the cabinet model, installed device model and structural distribution data to obtain an assembly model, and determine whether there is installation space for installing the pre-installed device model in the assembly model. If so, the pre-installed device model is installed in the assembly model and the installation position data is output; if not, the installed device models with installation margin are screened from the assembly model for shuffled arrangement, and are re-planned and arranged with the pre-installed device model and the arrangement data is output.

[0010] Principles and advantages:

[0011] 1. Setting of data acquisition module and requirement analysis module. The data acquisition module first obtains the function expansion requirements of the ACU controller, and then the requirement analysis module selects the function modules that meet the function expansion requirements from the preset hardware database. In this process, the selection of function modules can be completed without excessive human participation, saving labor costs.

[0012] 2. The setting of the model matching module and the space planning module. After screening out the functional modules that meet the functional expansion requirements, the model matching module is used to match the pre-installed device model of the corresponding functional module. At the same time, the model matching module will also match the cabinet model and the installed device model, and then it will be handed over to the space planning module for assembly to obtain the assembly model. The assembly model can restore the actual installation environment of the current ACU cabinet, so as to facilitate advance planning and design before the actual installation, thereby reducing the need for a large amount of manpower and time costs in the actual installation later. Among them, if it is determined that there is an installation space for installing the pre-installed device model in the assembly model, the pre-installed device model can be installed in the assembly model and the installation position data can be output to facilitate the staff to perform actual installation according to the installation position data, reduce the probability of actual installation errors, thereby improving the efficiency of installation, and achieving the purpose of saving time and manpower costs. If it is determined that there is no installation space for the pre-installed device model in the assembly model, the installed device models with installation margins are selected from the assembly model for random arrangement, and re-planned and arranged with the pre-installed device model and the arrangement data is output, which will further squeeze the available space in the ACU cabinet, thereby improving the utilization efficiency of the ACU cabinet and achieving the purpose of saving equipment costs. In addition, the functional module is designed as a hot-swappable module, and the faulty module can be replaced without shutting down the processor, which greatly improves the work efficiency when actually installing according to the installation position data and arrangement data.

[0013] Furthermore, the data acquisition module is also used to obtain the structural data of the underground urban integrated pipe gallery; the server also includes:

[0014] Function prediction module: used to analyze and predict the functional expansion needs in subsequent time periods based on the structural data of underground urban integrated pipeline corridors.

[0015] The setting of the function prediction module can analyze and predict the functional expansion needs in subsequent time stages through the structural data of the underground urban integrated pipeline corridor, thereby facilitating the planning and setting of the space planning module to reserve enough space in the ACU cabinet in advance to meet the access of new equipment and sensors in the future.

[0016] Further, the installation space includes a surplus installation space and a reserved installation space, the reserved installation space is a first priority for installing a pre-installed device model, and the surplus installation space is a second priority for installing a pre-installed device model.

[0017] The setting of spare installation space and reserved installation space facilitates the access of new equipment and sensors in the future. The setting of first priority and second priority facilitates the installation of the equipment to be installed in the predetermined position, following the planning arrangement of the space planning module, so as to effectively utilize the space inside the ACU cabinet. At the same time, there is no need for manual thinking and planning, which greatly improves work efficiency.

[0018] Furthermore, the space planning module is also used to plan the ACU main cabinet and ACU sub-cabinet according to the structural data of the underground urban integrated pipeline corridor, as well as plan the setting locations of the ACU main cabinet and ACU sub-cabinet when it is determined that there is no surplus installation space and reserved installation space in the assembly model, and there is no installation environment after the installed device model is shuffled.

[0019] When there is no space for installation in the assembly model, the ACU main cabinet and ACU sub-cabinet will be planned according to the structural data of the underground urban integrated pipeline corridor, and the corresponding setting positions will be planned. By fully targeting the structural characteristics of the underground urban integrated pipeline corridor, the ACU main cabinet and ACU sub-cabinet will be reasonably arranged to meet the access of new equipment and sensors in the future, while saving the cost of the integrated pipeline corridor monitoring system.

[0020] Furthermore, the ACU main cabinet and the ACU sub-cabinet communicate via DeviceNet fieldbus or EtherNet / IP industrial Ethernet.

[0021] Communicating via DeviceNet fieldbus or EtherNet / IP industrial Ethernet can ensure communication effectiveness and save the cost of the underground urban integrated pipeline corridor monitoring system.

[0022] A second object of the present invention is to provide a function expansion method for an ACU controller, the method being applied to the above system and specifically comprising the following steps:

[0023] Data collection step: obtaining the function expansion requirements of the ACU controller, obtaining the size data of the ACU cabinet corresponding to the ACU controller, and obtaining the model data and structural distribution data of each functional module of the ACU controller; the functional module is a hot-swappable module;

[0024] Requirements analysis step: select functional modules that meet the functional expansion requirements from the preset hardware database;

[0025] Model matching step: matching the pre-installed device model of the corresponding functional module from the preset model database, matching the cabinet model of the corresponding ACU cabinet from the preset model database according to the size data of the ACU cabinet, and matching the corresponding installed device model from the preset model database according to the model data of each functional module of the ACU controller;

[0026] Space planning steps: Assemble the model according to the cabinet model, installed device model and structural distribution data to obtain the assembly model, and determine whether there is installation space for installing the pre-installed device model in the assembly model. If so, install the pre-installed device model in the assembly model and output the installation position data; if not, select the installed device models with installation margin from the assembly model, shuffle them, and re-plan and arrange them with the pre-installed device model and output the arrangement data.

[0027] Principles and advantages:

[0028] 1. Setting of data collection step and requirement analysis step. In the data collection step, the function expansion requirements of the ACU controller are first obtained, and then in the requirement analysis step, the function modules that meet the function expansion requirements are screened from the preset hardware database. In this process, the selection of function modules can be completed without excessive human participation, saving labor costs.

[0029] 2. The setting of the model matching step and the space planning step. After screening out the functional modules that meet the functional expansion requirements, the model matching step is used to match the pre-installed device model of the corresponding functional module. At the same time, the model matching step will also match the cabinet model and the installed device model, and then the space planning step is used for assembly to obtain the assembly model. The assembly model can be used to restore the actual installation environment of the current ACU cabinet, so that advance planning and design can be carried out before the actual installation, thereby reducing the need for a large amount of manpower and time costs during the actual installation in the later stage. Among them, if it is determined that there is an installation space for installing the pre-installed device model in the assembly model, the pre-installed device model can be installed in the assembly model and the installation position data can be output to facilitate the staff to perform actual installation according to the installation position data, reduce the probability of actual installation errors, and thus improve the efficiency of installation, so as to achieve the purpose of saving time and manpower costs. If it is determined that there is no installation space for the pre-installed device model in the assembly model, the installed device models with installation margins are selected from the assembly model for random arrangement, and re-planned and arranged with the pre-installed device model and the arrangement data is output, which will further squeeze the available space in the ACU cabinet, thereby improving the utilization efficiency of the ACU cabinet and achieving the purpose of saving equipment costs. In addition, the functional module is designed as a hot-swappable module, and the faulty module can be replaced without shutting down the processor, which greatly improves the work efficiency when actually installing according to the installation position data and arrangement data.

[0030] Furthermore, the data collection step also acquires the structural data of the underground urban integrated pipe gallery; and further comprises the following steps:

[0031] Function prediction step: Analyze the structural data of the underground urban integrated pipeline corridor to predict the functional expansion needs in the subsequent time period.

[0032] The setting of the function prediction step can analyze and predict the functional expansion needs in subsequent time stages through the structural data of the underground urban integrated pipeline corridor, thereby facilitating the planning and setting of the space planning module to reserve enough space in the ACU cabinet in advance to meet the access of new equipment and sensors in the future.

[0033] Further, the installation space includes a surplus installation space and a reserved installation space, the reserved installation space is a first priority for installing a pre-installed device model, and the surplus installation space is a second priority for installing a pre-installed device model.

[0034] The setting of spare installation space and reserved installation space facilitates the access of new equipment and sensors in the future. The setting of first priority and second priority facilitates the installation of the equipment to be installed in the predetermined position, following the planning arrangement of the space planning module, so as to effectively utilize the space inside the ACU cabinet. At the same time, there is no need for manual thinking and planning, which greatly improves work efficiency.

[0035] Furthermore, the space planning step is: when it is determined that there is no surplus installation space and reserved installation space in the assembly model, and there is no installation environment after the installed device model is shuffled, the ACU main cabinet and ACU sub-cabinet are planned according to the structural data of the underground urban integrated pipeline corridor, and the setting positions of the ACU main cabinet and ACU sub-cabinet are planned.

[0036] When there is no space for installation in the assembly model, the ACU main cabinet and ACU sub-cabinet will be planned according to the structural data of the underground urban integrated pipeline corridor, and the corresponding setting positions will be planned. By fully targeting the structural characteristics of the underground urban integrated pipeline corridor, the ACU main cabinet and ACU sub-cabinet will be reasonably arranged to meet the access of new equipment and sensors in the future, while saving the cost of the integrated pipeline corridor monitoring system.

[0037] Furthermore, the ACU main cabinet and the ACU sub-cabinet communicate via DeviceNet fieldbus or EtherNet / IP industrial Ethernet.

[0038] Communicating via DeviceNet fieldbus or EtherNet / IP industrial Ethernet can ensure communication effectiveness and save the cost of the underground urban integrated pipeline corridor monitoring system. BRIEF DESCRIPTION OF THE DRAWINGS
