Compared with other brake machine, three roller brake machine's main advantages are: low cost, high reliability and durability. When choosing three roller gates, need to focus on the following indicators:
1, reliability: the reliability of the brake machine is based on the reliability of the various parts of the brake machine and integrated way. Choose good quality parts is the foundation, such as card reader, controller, display, etc.; Integration mode mainly the design and selection of the control unit and communication methods. Lightning protection components have also is related to the reliability of the equipment.
2, rotating life: brake machine is a constant movement of the body, the mechanical wear and fatigue of parts is inevitable, mechanical rotating life is one of the key indicators. Can be judged from the action mechanism, material selection, of course have formal institutions test report is the best;
3, the case material: brake machine for common people, all kinds of external force is frequent, mechanical strength is an important consideration; Brake machine running for a long time, is a "gateway", ought to be beautiful, so choose 1.5 2.0 mm stainless steel material is necessary. Stainless steel material is divided into many types, had better use 304 stainless steel.
4, movement principle: three rod movement is a major part of the brake machine, mechanical and electric, has adopted the international big company. In performance mainly focus on mechanical life, rail pressure, running noise, and the size of the thrust (touch), whether the balance, parts for easy replacement, etc.; On the function, can automatically rod (as needed), etc.
5, bar code reader at the top of the glass material: bar code reader above must be transparent, using organic glass of low cost, easy fabrication and installation, but after repeatedly brush ticket, glass will wear coarse, affect the bar code read speed and accuracy, so we must adopt wear-resisting quartz glass;
6, check-in speed: brake machine passing through the heavy traffic in the recount traffic speed is an important indicator. Check-in speed depends on the brake machine control mode, communication networking mode, recount processing software, mechanical movement speed. In general, the brake machine response speed within 500 ms.
7, environmental requirements: in the outdoor open-air occasion, the high requirement of humidity and temperature. Electronic circuit design of complex brake machine, it is difficult to applied in open environment. Brake machine shell can be designed rainproof, but moisture condensation and high temperature is inevitable, so use moisture, high temperature resistant parts is very important. Choose to have open application experience of the gate is wise.
