The switch made by the switch manufacturer replaces the AC motor drive under the control of the current drive mode in the small-power high-precision automatic transmission system. Its main features are small size, high output power, low noise, maintenance-free, low-rotation inertia control, and high control accuracy. These advantages are very difficult to achieve in the exchange drive. Retractable components mounted in aluminum alloy housings, signal generation equipment, random inspection generators, emergency power supply, judgment and processing of information read from the card, and application pass signals to the main control board. Power off two-way free traffic, power automatically restore the lock function, in order to quickly organize personnel evacuation in case of emergency.
When the valid card is read, after the pedestrian enters, the driver only needs to gently turn the door to open the door, automatically reset, two-way access, and the four doors are always in the closed state. Each time the revolving door is rotated by 90 degrees, the switch made by the switch manufacturer has automatic Reset function, if the passer does not pass within the specified time after the card is read, the system will automatically cancel the passer's current pass, and the limited time can be set by the administrator. When the resistance of the telescopic arm is reset, the motor will automatically bounce or automatically stop working within a specified time, and the intensity is very small. At the same time, an audible and visual alarm signal is issued.
