Description

Technical Field

[0001] The utility model relates to a gate machine, in particular to a driving circuit of a full-automatic three-roller gate. Background Art

[0002] The gate is a channel blocking device, which is mainly used in urban rail transit management and ticket gate systems to manage the flow of people and regulate the entry and exit of pedestrians. Among the traditional channel gate types, the three-stick gate has a clever structure and good anti-tailgating and anti-reverse effects, and is used in many consumer ticket inspection and attendance scenarios.

[0003] like Figure 1 As shown, Figure 1 The utility model relates to an installation structure of a tripod turnstile in the prior art.

[0004] Currently, the mainstream three-stick gates are divided into semi-automatic three-stick gates and fully automatic three-stick gates. The semi-automatic three-stick gates control the locking of the movement through electromagnets and mechanical mechanisms. The noise and vibration of the entire operation are relatively large. At the same time, because the locking mechanism is hard-connected, it is not resistant to collision and is easily damaged.

[0005] Since the power supply from the gate rod of the tripod turnstile to the main control chip is only powered by a step-down circuit without any isolation circuit measures, there is a certain probability that the reverse electromotive force of the motor will impact the power supply and the main control chip.

[0006] The gate drive of the traditional gate machine movement drive circuit is controlled by only one PWM, which cannot achieve hybrid drive and cannot control the position loop of the motor. Utility Model Content
