Electronic access control in the application of the most basic requirements
The main purpose of the access control security system is to prevent losses and prevent crime, so it must have extremely high reliability. An access control security system, most of its operation may not have a police situation, so there is no need to alarm, the probability of the alarm need to alarm is generally very small, but if the alarm system failure in this very small probability, it often means that disaster has come. Therefore, in all stages of design, construction and use of access control security systems, reliability design (redundancy design) and reliability management must be implemented to ensure the high reliability of products and systems.
In the system design, equipment selection, commissioning, installation and other links are strictly implemented in the national or industry standards, as well as the public security department related to safety technology prevention requirements, the product must be a number of authoritative certification, and has a large number of typical users, many years of normal operation.
Access control and security systems are used to protect people and property, so the system itself must be safe. The high safety mentioned here, on the one hand, refers to the natural or quasi-natural attributes of the product or system, which should ensure the safety of equipment and system operation and the safety of operators, such as: the equipment and system itself should be able to prevent high temperature, low temperature, warmth, smoke, mold, rain, and can prevent radiation, electromagnetic interference (electromagnetic compatibility), impact, collision, fall, etc., the operation safety of equipment and systems also includes fire prevention, lightning protection, explosion prevention, electric shock, etc.; On the other hand, the access control and security system should also have the function of anti-man-made destruction, such as: a protective shell with anti-vandalism, and an anti-demolition alarm, anti-short circuit and open circuit.
With the continuous improvement of people's requirements for all aspects of access control systems, the application range of access control systems is becoming more and more extensive. People's application of access control system is not limited to a single entrance and exit control, but also requires that it can not only be applied to access control, attendance management, security alarm, parking lot control, elevator control, building automation, etc. in intelligent buildings or intelligent communities, but also can be linked with other systems and other control functions.
The access control system should choose an open hardware platform, with a variety of communication methods, to achieve a good foundation for the interconnection and integration between various devices, and also requires that the system should have standardized and modular components, with great flexibility and expansion.
