Intelligent houses are selected with fully automatic automatic control systems to consider the diverse requirements of community owners, managers and users in housing management methods. In the new project of Yili Group's Food Science R&D Trend Management Center, under the framework of opening to the outside world, Damei used the Loyteciot residential management system to create cross-building, cross-system software, standardized management, and decentralized control of various mechanical equipment, which not only applied various communication protocols and IP connection network technologies, but also helped community users reduce the cost of system software integration and configuration.
Yili Group is a leading brand enterprise in the dairy industry, and is also strictly supervised for new projects and the selection of manufacturers of intelligent building systems, hoping that the technical nature of housing is not only the basic overall planning of system software, but also needs to consider the integration of cross-house, complex housing machinery and equipment, and multi-level application, and has a simple and reliable system architecture diagram, so as to truly complete the role of convenient maintenance, high-efficiency operation, environmental protection and energy saving.
The latest project of Yili Dairy and Food R&D Trend Management Office is in four areas, including the Comprehensive Industrial Zone, the Archives Network Information Center, the Hotel Engineering Building Management Office, and the Yili Dairy Financial Industry Sharing Center. How to effectively integrate different residential and complex residential subsystems in industrial zones and establish a cross-engineering, cross-system, and efficient intelligent management system is an important topic.
In response to customers' requests for an efficient converged service platform, Delta presented LOYTEC's IoT housing management system with LOYTEC's intelligent building solution, which can integrate customers' basic property management services to complete the platform-based and centralized management method and decentralized control of various machinery and equipment.
DeltaLoytec's smart building solutions are built on an open, all-IP network that not only works with national standard communication protocols, but also features RS-485 (modbusrtu/bacnetms/tp) that can be integrated with Bacnetip/modbustcp for fast cross-system software integration. According to the single service platform of multi-task fusion and data visualization, the optimization of cross-construction, cross-system software, software control of cold and hot systems, and software operation is completed.
In addition to the fact that each control board is equipped with 26 I/O levels to be suitable for multi-level applications, Delta's solution selects the newly released LOYTECL-IOB-589 control board as a key key system software product, in addition to its built-in ModbusRTU communication socket, which does not need to add other machines and equipment to the shopping cart to carry out the conversion.
According to the solution, the clearly proposed solution is conducive to improving the automatic control system such as refrigerator unit, VRV multi-online air conditioning and refrigeration unit, heat exchanger generator set, power distribution system, exhaust system, etc. In view of the abnormal external gas, the system software can improve the expected effect of environmental protection and energy conservation and environmental protection of the software of the high-energy home decoration household central air conditioning system, automatically adjust the load, select the operation mode of long and short routes, improve the application period of industrial equipment, and ensure the effective operation of industrial equipment
The revised scheme can not only consider the customer's requirements for the multi-stage application of housing construction and cross-system software, but also greatly reduce repeated purchases, reduce the convergence configuration time and network setup costs, and save more than 20% of the configuration convergence cost. The simple structure is more convenient for the management personnel to maintain and manage the management method after the fact, and the IP connection network also makes the system software transmission more rapid, and improves the linkage rate of the system software, which can not only consider the company's energy management system and power energy form regulations, but also has excellent environmental protection and energy saving practical effects in the long run
