What are the design principles of electronic truck scale weighing management system?

Design principle of electronic truck scale weighing management system 1. Principle of reliability. The system and hardware equipment follow the principle of 24 hours uninterrupted stable, reliable operation, and can adapt to extremely harsh working environment. In the design, the system and hardware equipment can still provide services to users when some faults occur, and can quickly recover normal operation. 2. Safety principle. The system should adopt strict hierarchical management technology, operation password and smart card authentication network permission design, double authentication, effectively avoid illegal leapfrog operation, all levels of management through customer requirements to define; For all data files have security protection measures, for the establishment of data, modify, delete and query should be authorized, in order to prevent illegal operation of data; The modification and deletion of original data are recorded in log files for future verification. 3. Principle of scalability. According to the system analysis, overall planning and development, the system is designed to be an economic benefit system with strong expansibility and expansion. The software system uses the advanced network development platform, takes the client/server architecture as the framework, combines the modularization and the structural design idea, that is, considering the current use of the ease of use, has the appropriate advance; The central system adopts the superposition module upgrade mode to gradually realize smooth expansion, reduce the complexity of system maintenance and upgrade, and improve the efficiency of system update, maintenance and upgrade. At the same time, the system has the ability to exchange and share data with other information systems, and the computer network ADAPTS to the wide area expansion and opening, so that the whole system is easy to operate, simple, efficient, and convenient for management to provide information in time. 4. Standardization principle. The system is implemented with the technology in line with industry standards as far as possible to ensure the quality of technology implementation and facilitate the daily maintenance and expansion of the system.
