[0003] In the traditional construction mode, after the communication room is ready for installation, it usually takes about 25 days to install the cabinet, wire, connect, and debug the single machine. This is mainly because the construction of the communication room includes a large number of cable laying and wire welding processes.

[0004] Based on this, a construction method of a communication room is urgently needed to improve the construction efficiency of the communication room and shorten the construction time. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] In the related technologies, railway communication rooms are generally system unit combination structures, that is, different systems are combined in the room with independent equipment racks, and various types of cables are used for physical connection through centralized power supply mode. There are many railway communication subsystems, including more than 20 subsystems such as transmission, data network, dispatching communication, mobile communication, and integrated video surveillance. The cabinet equipment is provided by each subsystem supplier, resulting in a large number of cabinets in the room and a large number of cables needing to be laid between cabinets. The construction content mainly includes cabinet installation, cable laying, wiring in the cabinet, welding wires, termination and other work. The wiring workload at the construction site is heavy, the labor volume is large, and the construction personnel are dense. Especially in the construction of existing line reconstruction projects, overseas projects, and harsh environment projects, there are also construction difficulties such as tight schedule, high technical difficulty, and poor construction environment.

[0022] The computer room construction method in the related art mainly has the following technical problems: 1. The equipment in the computer room cabinets varies in style and form, lacking overall planning. 2. When the equipment is expanded, on-site operations have a wide impact on adjacent operating equipment, posing a safety hazard. 3. The rack wiring lacks overall planning for short- and medium-term expansion needs. Once a new line is expanded, it is easy to cause uneven pressure on the cables of the trunk wiring rack, which affects the overall layout of the equipment wiring to a certain extent. 4. There is a gap between the process standards of the equipment supplier's factory wiring and the current construction process standards of the railway communication profession. 5. The construction phase is restricted by equipment selection, procurement negotiations, and computer room delivery, which can easily cause delays in the equipment installation period.

[0023] In view of the above technical problem of long construction period of communication room in related technologies, the embodiment of the present application provides a factory construction method for railway communication room, which mainly improves the engineering design link compared with the traditional construction process, and newly adds three links: factory pre-installation and pre-configuration, factory testing, and on-site assembly construction. Figure 1As shown, this method mainly includes: factory engineering design, factory pre-installation and pre-configuration, factory testing and on-site assembly construction. The factory construction process of the railway communication room is adopted to cancel, optimize or pre-position as many labor-intensive and high-risk operations (such as welding wires, cable laying, termination, etc.) in traditional construction site operations to the factory prefabrication stage curing process as possible. At the same time, the installation and testing work that usually takes 25 days on the construction site can be shortened to only 7-10 days on-site construction period. While greatly shortening the on-site construction period and improving the efficiency of engineering construction, it can significantly resolve the quality and safety risks in the current equipment room construction, stabilize the curing construction process, and ensure the safety and quality of the project.

[0024] The following, in conjunction with the accompanying drawings, describes in detail the factory construction method of the railway communication room provided by the embodiment of the present application through specific embodiments and their application scenarios.

[0025] like Figure 2 As shown, an embodiment of the present application provides a method for factory construction of a railway communication room, which may include the following steps 201 to 203: Step 201 : divide the communication system into subsystems, and generate a cabinet equipment layout diagram, a modular circuit diagram, and an inter-cabinet wiring diagram based on the subsystem division results, taking the cabinets of the communication room as basic units.

[0026] The cabinet equipment layout diagram is used to indicate the general equipment that needs to be installed in each cabinet included in each subsystem; the modular circuit diagram is used to indicate the connection relationship between the general equipment in each cabinet.

[0027] Step 202: Based on the cabinet equipment layout diagram, the modular circuit diagram, and the cabinet wiring diagram, the common equipment of each subsystem is pre-assembled in the factory, and the communication system obtained after the pre-assembly is tested.

[0028] The test of the communication system includes: a conduction test and a simulation test.

[0029] For example, in the traditional mode, all processes are completed on site, and after the wiring is completed, the conduction and simulation tests are carried out in sequence. In the factory construction method of the railway communication room provided in the embodiment of the present application, a new factory pre-installation and pre-configuration link is added, and the pre-configuration construction is carried out according to the drawings obtained by the factory engineering design. Each indoor communication system is based on a cabinet as a unit, and the indoor equipment installation and wiring are completed in the pre-configuration factory, and the equipment is disassembled, marked and transported after the factory test is completed.

[0030] Exemplarily, in the embodiments of the present application, in the pre-installation and pre-configuration link, unlike the traditional mode in which equipment transportation, installation and wiring construction are carried out only after all equipment has arrived on site, the factory-based construction immediately carries out the procurement of general cabinets and corresponding cables after obtaining the construction drawings. After the handover of the computer room, there is no need to wait for the design liaison meeting of the communication subsystem to be held to organize the installation and wiring of the equipment. After the subsystem equipment arrives for acceptance, secondary construction prefabrication and cable connection are carried out. Fiber optic patch cords, network patch cords, and two-megabit plugs are prefabricated and completed centrally in the factory. This link no longer needs to be completed on site like all the processes of cabinet installation and wiring in the traditional process. Pre-installation and pre-configuration makes part of the workload no longer restricted by time, space, and professional interfaces, creating a certain degree of "freedom" for engineering construction, and is the most important link for factory-based construction to improve efficiency and reduce costs.

[0031] Step 203: After the test is completed, the communication system is marked and disassembled, and the disassembled cabinet is transported to the computer room and assembled according to the markings to complete the construction of the communication room.

[0032] For example, in the embodiment of the present application, the above step 201 may further include the following steps 201a1 and 201a2: Step 201a1, obtaining the equipment room layout diagram and the construction wiring diagram of the communication equipment room.

[0033] Step 201a2: Based on the equipment room layout diagram and the communication equipment room construction wiring diagram, the cabinet equipment layout diagram and the modular circuit diagram are obtained by adjusting the combination arrangement table with the cabinet as the basic unit.

[0034] The combination arrangement table is used to describe the connection relationship between the basic units in the cabinet.

[0035] For example, the equipment room layout diagram and the communication equipment room construction wiring diagram can be designed first by traditional design methods, and then the cabinet equipment layout diagram and the modular circuit diagram with the cabinet as the basic unit are formed by adjusting the combination arrangement table.

[0036] Exemplarily, after the above step 201a2, the above step 201 may further include the following step 201b: Step 201b: Generate the inter-cabinet wiring diagram between the cabinets based on the modular circuit diagram.

[0037] For example, in the construction design phase, based on the traditional equipment room layout diagram and communication equipment room construction wiring diagram, the general equipment layout diagram of the standard room and the general cabinet rack cable distribution diagram are added, providing data support specifically for factory construction, so that when the cabinets are delivered to the site, the construction personnel can directly construct according to the drawings.

[0038] Specifically, the above step 202, for the conduction test step, may further include the following step 202a: Step 202a: A multi-core cable continuity tester that is matched with bundled cables and connectors is used to perform a continuity test on open and short circuits of wiring cables between cabinets.

[0039] Specifically, the above step 202, for the step of simulation test, may further include the following step 202b: Step 202b: inspect the transmission system, access network, telephone exchange, data communication network, wired dispatch communication, mobile communication, conference television, telegraph, integrated video surveillance, dedicated emergency communication, clock synchronization, time synchronization, integrated wiring, power supply and equipment housing environment monitoring, and integrated network management system.

[0040] For example, in the on-site prefabricated construction link, after the equipment house is ready, the general cabinet installation, standard interface number configuration wiring, cable conduction, etc. can be carried out on the construction site. After all the subsystem equipment is in place, the subsystem prefabricated assembly, wiring, and single-machine debugging are carried out. The deduction and calculation take about 7-10 days to complete. In the traditional model, after the house is ready for installation, the cabinet installation, wiring, conduction, and single-machine debugging usually take about 25 days to complete. This link is the closing link for the complete communication system equipment. The pre-installed cabinets are finally assembled on site. After completing relatively simple wiring, conduction, and debugging, they can welcome the overall acceptance.

[0041] Specifically, the above step 203 may further include the following step 203a: Step 203a: Based on the inter-cabinet wiring diagram and the markings of each cabinet, complete the cable connection between the cabinets.

[0042] In a possible implementation, the above cabinets are connected by cables through a plug-in wiring method. Wiring interfaces are reserved between the cabinets by presetting inter-rack wiring interfaces.

[0043] It can be understood that since the modular design is carried out with the cabinet as the basic unit in the embodiment of the present application, the circuits and devices inside the cabinet can be assembled in the factory. After the test is successful, the cabinet can be transported to the computer room for assembly. Therefore, the wiring between the cabinets can be completed by plug-in wiring, and the construction of the communication room can be completed.

[0044] Specifically, after the above step 203a, the above step 203 may further include the following step 203b: Step 203b: After completing the cable connection between the cabinets, an indoor simulation test is performed, and after the test passes, the construction of the communication room is completed.

[0045] For example, after the signal machinery room is ready for equipment installation, the factory-made equipment transported from the pre-installed base will be assembled and restored at the construction site. There is no need for a large number of wiring and welding processes like in the traditional mode. The on-site assembly construction can be completed by simply reconnecting the cabinet lines according to the markings. Then, only an indoor simulation test is required to complete the entire railway communication room factory construction process.

[0046] In a possible implementation, in order to ensure that the cabinet is not damaged during transportation, the above step 203 may further include the following step 203c: Step 203c: perform anti-vibration treatment on the disassembled cabinet to prevent the cabinet from being damaged by vibration generated during transportation.

[0047] It should be noted that the factory-based construction method for railway communication room provided in the embodiment of the present application can eliminate, optimize or pre-position as many labor-intensive and high-risk operations (such as welding wires, cable laying, termination, etc.) in traditional construction site operations to the factory prefabrication stage curing process as possible, and shorten the installation and testing work that usually takes 25 days on the construction site to only 7-10 days on site. The main technical effects are: 1. Through the unification of equipment cabinets and the pre-setting of interfaces for inter-rack wiring, the overall and local wiring planning of the communication room has been developed towards a more standardized layout, increasing the utilization rate and overall appearance of the communication room. The installation and wiring of communication professional equipment has changed from complexity and diversity to unification and simplification. 2. It can realize the re-combination planning of the installation positions of the same type of system equipment, which is conducive to the partition management according to the system function in the room and the reservation of system expansion in the short term. 3. Since the trunk cables have been reserved, it is conducive to reducing the construction impact range of the later equipment expansion. 4. The use of plug-in connection facilitates fault judgment through cable replacement verification, improving the efficiency of fault judgment; 5. The cable connection method between equipment has changed from welding and card connection to plug-in connection, which is conducive to reducing the skill requirements for maintenance personnel in the emergency repair stage. 6. Through the professional cable terminal pre-configuration in the factory, the quality problems caused by objective factors such as the quality of construction tools and the technical level of on-site operators are reduced. 7. Since the equipment supplier resources of the general rack are sufficient and the supply cycle is relatively guaranteed, the risk of rush work caused by delayed procurement and delivery of system equipment is reduced. 8. The application of bundled cables reduces the workload of on-site cable laying, which is conducive to improving on-site construction efficiency. The rack wiring inside the equipment is transferred from the manufacturer to the construction unit, which is conducive to improving the process quality.

[0048] The factory construction method of a railway communication room provided in an embodiment of the present application comprises the following steps: first, dividing the communication system into subsystems, and generating a cabinet equipment layout diagram, a modular circuit diagram and a cabinet wiring diagram with the cabinet of the communication room as the basic unit based on the subsystem division result; the cabinet equipment layout diagram is used to indicate the general equipment that needs to be installed in each cabinet of the cabinets included in each subsystem; the modular circuit diagram is used to indicate the connection relationship between the general equipment in each cabinet; and based on the cabinet equipment layout diagram, the modular circuit diagram and the cabinet wiring diagram, the general equipment of each subsystem is pre-assembled in the factory, and the communication system obtained after the pre-assembly is tested; the pre-assembly includes: assembling the general equipment of each subsystem and connecting them with cables; then, after the test is completed, the communication system is marked and disassembled, and the disassembled cabinets are transported to the room for assembly according to the markings to complete the construction of the communication room; wherein the test of the communication system includes: conduction test and simulation test. In this way, by pre-assembling and testing the cabinets in the factory and then transporting them to the computer room for assembly, the construction efficiency of the communication room is greatly improved and the construction time is shortened.
