Description

Technical Field

[0001] This application relates to the fields of building construction and intelligent system integration, and in particular to an integrated construction process for the intelligent design and construction of a low-temperature laboratory building. Background Technology

[0002] Cryogenic laboratories, as crucial facilities in scientific research and industrial production, play a pivotal role in modern technological development. With the deepening of scientific research and the increasing demands for precision and stability in industrial production, the importance of cryogenic laboratories is becoming increasingly prominent. They provide precise low-temperature environments for various experiments and production activities, ensuring the accuracy of experimental results and the stability of product quality. For example, in materials science research, low-temperature environments can alter the physical properties of materials, helping scientists explore new material characteristics; in the electronic chip manufacturing process, cryogenic laboratories can simulate extreme environments to test chip reliability. Therefore, the demand for cryogenic laboratories is increasing with technological advancements, and the requirements for their intelligence, automation, and efficiency are also becoming increasingly stringent.

[0003] Traditional cryogenic laboratory construction typically employs a phased approach. First, the building structure is constructed—a relatively independent process focusing primarily on stability and spatial layout. Next, video surveillance, access control, intrusion alarm, building equipment monitoring, elevator monitoring, and a five-way intercom system are installed. These systems operate independently, achieving coordinated control through later integration. During video surveillance installation, appropriate cameras and storage devices are selected based on specific monitoring needs, and wiring and debugging are performed. Access control systems include card readers and access controllers, with appropriate access rules set. Intrusion alarm systems deploy various detectors and alarm hosts to monitor and alert on abnormal intrusions. Building equipment monitoring systems provide real-time monitoring and control of various laboratory equipment. The elevator monitoring and five-way intercom system ensures safe elevator operation and uninterrupted communication in emergencies.

[0004] However, this traditional construction method has significant drawbacks. The system design and construction are fragmented and lack integration, leading to low construction efficiency. The installation and commissioning of each system must be carried out separately, increasing construction time and costs, and compatibility issues are prone to arise during later integration. Furthermore, the fragmented system design makes efficient intelligent management difficult, failing to meet the real-time monitoring and rapid response requirements of modern cryogenic laboratories. In emergencies, the lack of timely and accurate coordination between systems may result in delayed information transmission, impacting the efficiency of problem-solving. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide an integrated construction process for the intelligent design and construction of low-temperature laboratory buildings.

[0006] A construction process integrating intelligent design and construction of a low-temperature laboratory building includes the following steps: S1. Integrated design phase: Integrate building structure design and intelligent system design to form integrated construction drawings.

During the main building structure construction phase, the pre-embedding of cable channels, grounding equipment, and equipment installation foundations for each intelligent system are completed simultaneously during the main structure construction process. The pre-embedding work is carried out in coordination with the main building structure construction process. S3. During the intelligent system installation phase, the installation of each subsystem device and cable laying of the intelligent system are carried out simultaneously. The main cable of the cable laying adopts shielded cable, and the branch cables are selected according to the appropriate cable type based on the transmission distance. S4. Integrated debugging phase, including single system function debugging and multi-system linkage scenario testing, the linkage scenarios include intrusion alarm linkage, entrance and exit abnormal linkage and elevator fault linkage.

[0007] By adopting the above technical solutions, integrated design is carried out before construction, and the architectural design and multiple intelligent system designs are completed simultaneously. The pre-embedding work of the intelligent systems is completed during the construction of the main building structure, which can reduce the steps of wall drilling and modification and rework during the later construction of intelligent systems, thereby shortening the construction cycle and improving construction efficiency. At the same time, the linkage interfaces of each subsystem of the intelligent system are reserved during the design, eliminating the need for additional configuration conversion equipment and software systems for integration and linkage later, thereby improving the compatibility of the intelligent system. Through integrated commissioning, multi-system linkage can be achieved, meeting the needs of modern low-temperature laboratories for real-time monitoring and rapid response.

[0008] Preferably, the video security monitoring system adopts a digital video implementation method, including a video management server, network storage device, video fusion device, screen wall, network switch and front-end cameras configured in the monitoring center.

It also has a fire emergency passage function.

[0011] By adopting the above technical solutions, the one-way passage mode, which uses facial recognition or contactless IC card verification for entry and button triggering for exit, can improve the convenience and security of personnel passage. It also has a fire emergency passage function, which can ensure that personnel can pass through without prior identification in emergency situations, and can receive fire linkage control signals to release access control, ensuring the safe evacuation of personnel. At the same time, combined with the integrated construction process, it can reduce the rework of later construction modifications, shorten the construction cycle, improve the compatibility of intelligent systems, realize efficient intelligent management, and meet the needs of modern cryogenic laboratories for real-time monitoring and rapid response.

[0013] By adopting the above technical solutions, the design of the building and intelligent system can be coordinated during the integrated design phase. Pre-embedded work and main structure construction can be carried out in tandem during construction. All subsystems of the intelligent system can be installed and debugged simultaneously. Combined with the intrusion alarm system, which includes an alarm host, infrared microwave dual-technology detectors, and emergency alarm buttons, the workload of later construction and modification can be reduced, and the system compatibility rate can be improved. Furthermore, the installation of tamper protection and independent zones between the detectors and the host allows the control and indication devices to issue audible and visual alarm signals when the alarm signal transmission line is open-circuited, short-circuited, the detector power line is cut off, or the equipment malfunctions, ensuring system security. Support for arming, disarming, and bypassing zones by time and area allows for flexible adjustment of the system's defense strategy. It accurately detects intrusion behavior or issues alarm signals when emergency alarm devices are triggered. It can also be linked with access control systems, video security monitoring systems, and other systems through a linkage control interface.

[0014] Preferably, the elevator monitoring and five-way communication system includes a car camera, a five-way communication host, and a communication cable.

[0019] By adopting the above technical solution, the cable channels, including the main and branch channels of each subsystem, are pre-buried during the construction of the main building structure. This allows the main cables of the video security monitoring and access control system to connect the park control center and the floor's low-voltage room, and the branch cables to extend to the pre-set installation area. This reduces the need for drilling and rework during the later construction of the intelligent system, thereby shortening the construction cycle and improving construction efficiency. Furthermore, since the cable channel planning is completed in the design phase, it helps the subsequent intelligent system to operate stably and smoothly, avoiding signal interference and transmission problems.

[0020] Preferably, the PLC controller of the equipment monitoring system is installed in the equipment room cabinet, the air quality detector and the manual start / stop button are fixed on the laboratory wall, and the air valve switch is connected to the PLC controller through a cable to realize status feedback.

[0021] By adopting the above technical solution, the building structure and intelligent system design are integrated into a unified drawing before construction. The pre-embedded work of the intelligent system is completed simultaneously during the construction of the main structure. Cables are laid according to requirements, and single-system debugging and multi-system linkage testing are carried out. The PLC controller of the equipment monitoring system collects environmental parameters through cables and executes ventilation interlock control. When a gas concentration alarm is detected, the exhaust fan and electric valve are automatically started. The PLC controller of the equipment monitoring system is installed in the equipment room cabinet, and the air quality detector and manual start / stop button are fixed to the laboratory wall. The air valve switch and the PLC controller are connected by cables to realize status feedback.

[0024] Preferably, each subsystem of the intelligent system has a pre-set linkage interface during the design phase. The interface supports compatibility and interoperability with fire protection systems and building automation systems, eliminating the need for additional conversion equipment in the later stages.

[0025] By adopting the above technical solutions, each subsystem of the intelligent system is pre-configured with linkage interfaces that support compatibility and interoperability with fire protection systems and building automation systems during the design phase. This eliminates the need for additional conversion equipment in the later stages, thereby improving the compatibility rate of the intelligent system and achieving structural synergy between systems.

Detailed Implementation

[0028] This application primarily employs an integrated construction process to build an intelligent system for a low-temperature laboratory, achieving the effect of improving construction efficiency and intelligent management. The following details... Figures 1-5 A further detailed description of this application.

[0029] The integrated construction process for intelligent design and construction of low-temperature laboratory buildings provided in this application includes an integrated design phase, a main building structure construction phase, an intelligent system installation phase, and an integrated commissioning phase. In the integrated design phase, the building structure design and intelligent system design are coordinated to form integrated construction drawings. During the main building structure construction phase, the pre-embedding of cable channels, grounding equipment, and equipment installation foundations for each intelligent system is completed simultaneously. The pre-embedding work is carried out in tandem with the main building structure construction process. In the intelligent system installation phase, the installation of equipment and cable laying for each subsystem of the intelligent system are carried out simultaneously. The main cable is Cat.6 STP shielded cable, and branch cables are selected according to the transmission distance. The integrated commissioning phase includes single-system function debugging and multi-system linkage scenario testing. Linkage scenarios include intrusion alarm linkage, entrance / exit anomaly linkage, and elevator malfunction linkage. This achieves the effects of shortening the construction cycle, improving construction efficiency, and increasing the compatibility of the intelligent system, meeting the requirements for real-time monitoring and rapid response. This is because the integrated design avoids rework in later modifications, the coordination of pre-embedding work and main building construction reduces additional construction steps, and the close cooperation between each phase and the pre-set linkage interfaces of the system make the entire construction process more efficient and orderly, with better compatibility and linkage between systems.

[0030] Specifically, the integrated design phase includes architectural structural design and intelligent system design.

[0031] The building structure design is the responsibility of the structural engineer, who must fully consider the laboratory's functional requirements, spatial layout, and load-bearing capacity. For example, the size and shape of the rooms must be rationally planned according to the type of experiments and equipment layout; the impact of low temperatures on building materials must be taken into account, and suitable building materials, such as wall materials with good thermal insulation properties, must be selected. The intelligent system design is completed by the intelligent system engineer. The intelligent system includes a video security monitoring system, access control system, intrusion alarm system, elevator monitoring and five-way intercom system, and equipment monitoring system. The video security monitoring system adopts digital video implementation, including a video management server, network storage devices, video fusion equipment, a video wall, network switches, and front-end cameras configured in the monitoring center. The video management server can be a high-performance server with powerful data processing and storage capabilities; the network storage devices can be disk arrays to meet the storage needs of large amounts of video data. The front-end cameras include indoor fixed bullet cameras and outdoor fixed bullet cameras, and the cameras support dual-stream characteristics to achieve live transmission and storage separately. Indoor fixed bullet cameras can be selected as 5-megapixel infrared integrated models, supporting low-light and corridor functions, suitable for indoor environments with dim lighting; outdoor fixed bullet cameras are equipped with surge protectors, and wide dynamic range cameras are selected for areas with significant light contrast, adaptable to different outdoor lighting conditions. The access control system includes access controllers, card readers, electric locks, and management software. The system is set to a one-way passage mode, i.e., entry uses facial recognition or contactless IC card verification, and exit uses button triggering, and has a fire emergency passage function. The access controller can be an access controller with offline working capability, ensuring that key information and recorded information are not lost after power failure; the card reader supports contactless IC cards, with an installation height of 1.2m, and the facial recognition access control terminal is installed at a height of 1.5m. The intrusion alarm system includes an alarm host, infrared microwave dual-technology detectors, and an emergency alarm button. The detectors and host are equipped with tamper protection and independent zones, supporting arming, disarming, and bypass settings for zones by time and area. The alarm control panel can be installed in the electrical rooms on the first floor of the experimental support equipment building and the electrical rooms in the radioactive solid waste storage hall, using a network architecture. Front-end detectors include passive infrared and microwave dual-technology detectors and emergency alarm buttons, installed at high and low positions in the radioactive waste storage hall and the accessible restroom on the first floor of the experimental support equipment building, respectively. The elevator monitoring and five-way intercom system includes a car camera, a five-way intercom control panel, and communication cables. The camera overlays floor signals and connects to the five-way intercom equipment. The communication cable uses a dedicated elevator traveling cable with reserved redundant length. The car camera is installed in the top corner of the car, powered by the elevator car lighting circuit. The dedicated elevator dome camera has a floor signal overlay unit. The five-way intercom equipment is installed in the park's comprehensive experimental fire and security control center, the machine room, the car top, the car, and at predetermined installation locations in the pit.The equipment monitoring system includes a PLC controller, air quality detectors, dampers, and exhaust fans. The PLC controller collects environmental parameters via cables and executes ventilation interlock control. When a gas concentration alarm is detected, the exhaust fan and electric valves are automatically activated. The PLC controller is installed in the equipment room cabinet. The air quality detectors and manual start / stop buttons inside and outside the room are fixed in the laboratory. The damper switches and feedback are installed in the exhaust system ducts and connected to the PLC controller via cables.

[0032] The design logic behind this approach is that the building structure provides the foundational space and support for the installation and operation of intelligent systems. The various subsystems of these intelligent systems work together to achieve comprehensive monitoring and management of the cryogenic laboratory. For example, the video security monitoring system monitors all areas of the laboratory in real time, the access control system controls personnel entry and exit, the intrusion alarm system promptly detects abnormal intrusions, the elevator monitoring and five-way communication system ensures elevator safety and emergency communication, and the equipment monitoring system adjusts the laboratory's environmental parameters. This combination enables the cryogenic laboratory to operate efficiently and safely.

[0033] Specifically, the main building structure construction phase includes the construction of the main building structure and the pre-embedded work of intelligent systems.

[0034] The main building structure is constructed according to the integrated design drawings to ensure the building's stability and safety. During construction, strict quality control is maintained, adhering to relevant building construction codes and standards. The pre-installation work for the intelligent system includes cable channel pre-installation, grounding equipment pre-installation, and equipment installation foundation pre-installation. Cable channel pre-installation includes the main and branch channels of each subsystem. The main cables for the video security monitoring system and access control system connect the park control center to the floor's low-voltage electrical room, while branch cables extend to the pre-designated installation areas. The video security monitoring system's branch cables and power cables run from the floor's low-voltage electrical room to the building's ground floor and rooftop entrances, main entrances, public corridors, elevator lobbies, equipment rooms, and electrical rooms, passing through communication lines and PoE power lines. In outdoor areas, conduits are pre-buried from the ground floor's low-voltage electrical room to the outdoor camera pole foundations, with lightning protection grounding interface channels reserved simultaneously. The pre-buried branch cable channels for the entrance / exit control system must run from the floor's low-voltage electrical room to each entrance / exit. The pre-buried main cables for the intrusion alarm system include conduits running from the ground floor low-voltage electrical room of the experimental support equipment building and the low-voltage electrical room of the radioactive solid waste temporary storage hall, connecting to the park's comprehensive experimental fire protection and security control center. Branch cables will be pre-buried in conduits from the low-voltage electrical rooms on the first floor of the experimental support equipment building and the low-voltage electrical rooms of the radioactive solid waste temporary storage hall, respectively, to the accessible restrooms and the radioactive waste temporary storage hall on the first floor of the experimental support equipment building. The pre-buried cable channels for the elevator monitoring and five-way intercom system will include conduits pre-buried in the low-voltage electrical shaft of the park's comprehensive experimental fire and security control center, connecting to each elevator machine room. The main cable channel for the equipment monitoring system will connect to the control center via pre-buried conduits in the low-voltage electrical shaft from the PLC controller installation location. Branch cables will be laid in conduits at the air quality detectors, manual start / stop buttons inside and outside the rooms, and wind pressure sensor installation locations, leading to the PLC controller installation location. Grounding equipment pre-buried installations must ensure good grounding to provide a safe electrical environment for the intelligent system. Equipment installation foundation pre-buried installations must accurately reserve installation locations and dimensions according to the installation requirements of each piece of equipment.

[0035] The construction of the main building structure and the pre-installation of intelligent systems are carried out in a coordinated manner. This avoids large-scale modifications to the building structure later, reducing construction time and costs. At the same time, the early pre-installation work also facilitates the subsequent installation of intelligent systems.

[0036] Specifically, the installation phase of the intelligent system includes the installation of equipment for each subsystem and the laying of cables.

[0037] The installation of each subsystem equipment is carried out according to the preset locations. During the installation of the video security monitoring system, indoor dome cameras and indoor fixed bullet cameras are installed at the pre-installed locations on the first floor and rooftop entrances / exits, main entrances / exits, public corridors, elevator lobbies, equipment rooms, and electrical rooms. Outdoor bullet cameras are installed on the upper sections of preset poles. Indoor cameras are powered uniformly via PoE from the low-voltage room switch, while outdoor cameras are powered via PoE. Lightning rods are installed at the top of the poles, and the grounding terminals of the surge protectors are reliably connected to the grounding electrode. For the entrance / exit control subsystem, card readers, door magnets, door opening buttons, and electric locks are installed at the entrances / exits respectively. The connection cables of the actuators outside the controlled area are enclosed for protection, and the tensile and bending strength of the input cable protection structure is no less than that of galvanized steel pipe. During the installation of the intrusion alarm system, passive infrared microwave dual-technology detectors and emergency help alarm buttons are connected to the alarm host via cables. During the installation of the elevator monitoring and five-way intercom system, the elevator car camera is first installed in the corner of the elevator car's top, and then the intercom devices are installed in the predetermined locations. During the installation of the equipment monitoring subsystem, air quality detectors and manual start / stop buttons inside and outside the room are fixed in the laboratory. Air valve switches and feedback mechanisms are installed inside the exhaust system ducts and connected to the PLC controller via cables. The main trunk cable uses Cat.6 STP shielded cable, while branch cables use Cat.6 UTP cable for transmission distances ≤100 meters and Cat.6 STP cable for transmission distances >100 meters.

[0038] The installation of equipment and cabling in each subsystem are coordinated to ensure that all devices in the intelligent system can be connected and operate normally. Proper cabling can reduce signal interference and guarantee system stability.

[0039] Specifically, the integrated debugging phase includes single-system functional debugging and multi-system linkage scenario testing.

[0040] Single-system functional debugging is performed for each subsystem. The video security monitoring subsystem must meet the following requirements: recording retention time ≥ 30 days, alarm pre-recording time ≥ 5 seconds, and clear, smooth images. The access control subsystem must meet the following requirements: card reading and recognition time to execution of opening / closing action ≤ 0.5 seconds, alarm information transmission time to the management center ≤ 2 seconds, and record storage time ≥ 180 days. The intrusion alarm subsystem must meet the following requirements: single controller alarm response time ≤ 2 seconds, and detectors must have no missed or false alarms. The equipment monitoring subsystem must meet the following requirements: accurate sensor data acquisition, PLC controller control accuracy meeting design requirements, and when an alarm is triggered by a room's emergency gas concentration, the room's duct electric valve and exhaust fan should be interlocked to start. When the emergency gas is extinguished, the exhaust fan and valve should be electrically closed. After the fire is extinguished, the valve should be electrically opened, and the exhaust fan should be interlocked to start. Multi-system linkage scenario testing includes intrusion alarm linkage, access abnormality linkage, and elevator malfunction linkage. Intrusion Alarm Linkage: When the passive infrared microwave dual-technology detector in the radioactive waste storage hall is triggered, the intelligent system will switch the corresponding area's view to the video security monitoring system within ≤3 seconds and start pre-recording. The intrusion alarm system will activate the audible and visual alarm, and the access control subsystem will lock all entrances and exits in the area. Entrance / Exit Anomaly Linkage: When simulating unauthorized entry into a laboratory room, the intelligent system will trigger an alarm in the access control system within ≤2 seconds, and the video security monitoring subsystem will capture the scene. The intrusion alarm subsystem will issue a notification, and the management center will receive the alarm information. Elevator Failure Linkage: When an emergency call is triggered in the elevator car, the intelligent system will immediately connect to the control center via the five-way communication system, and the video security monitoring system will automatically switch to the elevator car view.

[0041] Single-system function debugging ensures that each subsystem can operate normally, while multi-system linkage scenario testing verifies the linkage and compatibility between subsystems, ensuring that the entire intelligent system can respond to various situations efficiently and accurately.

[0042] The implementation principle of this embodiment is as follows: This embodiment organically combines building structure design and intelligent system design through integrated design, avoiding the problems caused by the decentralized design and construction of various systems in traditional construction methods. The pre-embedding work of the intelligent system is carried out simultaneously during the construction of the main building structure, reducing the workload and difficulty of later construction and improving construction efficiency. During the intelligent system installation phase, equipment installation and cable laying are carried out in a reasonable manner, ensuring the stability and reliability of the system. The integrated commissioning phase tests single and multi-system linkage to ensure that the system can operate normally and achieve efficient intelligent management. This integrated construction process optimizes the construction process of the cryogenic laboratory as a whole, improves construction efficiency and system compatibility, and meets the needs of modern cryogenic laboratories for real-time monitoring and rapid response. Compared with traditional construction methods, it has significant advantages and represents a significant improvement and enhancement to existing cryogenic laboratory construction technology.
