First of all, to ensure the security of the front-end equipment, mainly refers to the card and card reader, it is recommended to use a more secure CPU card and card reader, because the encryption function of the CPU card is far stronger than the previously commonly used Mifare1 card. However, the real application of the specific analysis of specific issues, from the cost point of view, the current Mifare1 cards and readers in the access control card system is the most widely used, but due to last year's "break the door" incident, Mifare1 card manufacturers also upgrade the encryption level Basically, it can meet the needs of regular users. For users with high encryption requirements, it is recommended to use a CPU card access control card.
At present, the user has a stable and reliable product quality in the card system for access control, which is the first requirement. Secondly, the function needs to be customized to meet the specific needs of the customer; the degree of integration is high, the software database is unified, and card issuance and cancellation are unified. Subsystems are unified in terms of transmission methods, easy to use, and friendly to man-machine interfaces.
The integrated application of the access control card as the first step of active defense, how to integrate the access control card and other security subsystems such as video surveillance, anti-theft alarm, patrol, firefighting, etc., to improve the efficiency of security protection, will also become At present, many product manufacturers and system integrators work together.
Chen Haiwen, deputy director of Guangzhou Taishang Information System Co., Ltd., believes that the "integration of the access control card" and other security subsystems is an inevitable development of the market. The specific linkage is as follows:
The access control card triggers the video surveillance system to automatically record or capture. It can be triggered directly by the hardware switch signal, or linked through the underlying protocol.
The integration of access control systems and burglar alarms will be even higher. Advanced access control masters can now integrate the functions of the control panel and access control panels design alarm input and output ports. Some PC software also integrates access control alarms, and can also display electronic maps. When an alarm occurs, it can automatically block pre-set key access doors.
Patrols and attendance often use access control readers and cards in the access control card system, selecting some of the appropriate locations for the access control readers as well as online patrolling and attendance checking;
The linkage between the fire protection system and the access control is mainly reflected in the fact that, when a fire alarm occurs, the corresponding access door is opened automatically for the escape of the personnel. It can be directly triggered by the hardware switch signal, or it can be linked through the underlying protocol.
Cold Rolled Stainless Steel Sheets
Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion resistance. It is an alloy steel that does not rust easily, but not absolutely. Stainless steel plate refers to the corrosion resistance of weak medium such as atmosphere, steam and water steel plate, and acid resistant steel plate refers to the corrosion resistance of chemical etched medium such as acid, alkali, salt steel plate.
According to the structure is divided into austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic ferritic biphase stainless steel plate and so on four categories? According to the main chemical composition of the steel plate or some characteristic elements in the steel plate to be classified into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate. According to the performance characteristics and use of steel plate classification, is divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting stainless steel plate, stress corrosion resistant stainless steel plate, high strength stainless steel plate. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, no magnetic stainless steel plate, easy cutting stainless steel plate, super plastic stainless steel plate. Currently, the commonly used classification method is according to the structural characteristics of steel plate and steel plate chemical composition characteristics and the combination of the two methods. Generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate and precipitation hardening type stainless steel plate or divided into chromium stainless steel plate and nickel stainless steel plate two categories.
Typical uses: pulp and paper equipment heat exchanger, mechanical equipment, dyeing equipment, film washing equipment, pipelines, coastal area building external materials, etc.
