Embodiment 1
[0033] Such as Figure 1 to Figure 3 As shown, a platform door blocking control method includes the following steps:
[0034] Detect whether the encoder of the motor used to drive the opening and closing of the platform door is blocked. If the encoder is blocked, the platform door enters the obstruction control mode. , the platform door is controlled according to the normal environment driving mode, that is, the platform door opens and closes normally. Judging whether the encoder is blocked can be judged by whether the pulse signal of the encoder changes. When the pulse signal does not change, the encoder is blocked. Otherwise, the encoder is not blocked.
[0035] When the platform door enters the obstruction control mode, it is necessary to further determine whether the platform door enters the driving mode of the person obstruction or the wind pressure obstruction driving mode. The driving mode of person encountering resistance refers to the platform door opening and closi...
Embodiment 2
[0047] This embodiment provides a door control unit, the door control unit is also referred to as DCU, the door control unit includes a collection module, a judgment module and an output module, the collection module is used to collect the encoder stall signal and the motor rotation signal , the acquisition module sends the collected signal to the judgment module, the judgment module sends the judgment result to the output module, and the output module outputs the corresponding output signal, so that the platform door enters the corresponding normal environment driving mode and the resistance control mode. one of them.
[0048] Specifically, the judging module outputs a judging result signal that the platform door enters one of the normal environment driving mode and the blocked control mode according to the encoder stall signal, and sends the judging result to the output module, and the output module outputs According to the corresponding output signal a, the platform door en...
Embodiment 3
[0062] This embodiment provides a platform door. The platform door is usually used in the subway, and can also be used in other places, such as the following bus platforms or passenger stations, etc., without specific limitations. The platform door includes the door control unit of the second embodiment, the door The control unit is used to control the opening and closing of the platform door.

Abstract
The invention relates to a platform gate resistance control method, a gate control unit and a platform gate. The method comprises the following steps of: stalling a detection coder; correspondingly making the platform gate enter one of a normal environment drive mode and a resistance control mode according to a stalling result of the detection coder, wherein the resistance control mode comprises aperson resistance drive mode and an air pressure resistance drive mode; and after the platform gate enters the resistance control mode, making a detecting motor rotate and correspondingly making theplatform gate enter one of the person resistance drive mode and the air pressure resistance drive mode according to a rotation result of the detecting motor. The platform gate resistance control method provided by the invention can be used for accurately judging the resistance condition of the platform gate, can realize accurate control on resistance met by the platform gate, can also be used forjudging whether the resistance met by the platform gate is air pressure resistance or not so as to judge whether the platform gate needs to enter the air pressure resistance control mode or not, and can also realize quite good control on opening and closing operation of the platform gate which meets the resistance caused by air pressure.
Description
technical field [0001] The invention relates to the technical field of platform door control, in particular to a platform door blocking control method, a door control unit and a platform door. Background technique [0002] The platform doors of urban rail transit such as subways are easily affected by tunnel wind pressure and obstruction by foreign objects, which may cause the platform doors to fail to open and close normally and affect the operating efficiency of the station. The tunnel wind pressure is usually caused by piston wind. The wind pressure will cause additional friction to the platform door, and the increase of the additional friction will lead to an increase in the resistance when the platform door is opened or closed, that is, the door resistance of the platform door will increase. The dynamic wind pressure will press the platform door and cause the door resistance of the platform door to change. The change of the door resistance will affect the detection of o...
