Problems solved by technology

However, this adjustment method requires manual adjustment according to the wind pressure, which is cumbersome to operate. Once the personnel do not adjust in time (usually it is difficult to adjust according to the wind pressure in time), the platform door cannot be closed in time; the other is that there are potential safety hazards , when the wind pressure formed by the piston wind in the tunnel is weakened, the clamping force formed by the closing of the platform door due to the untimely adjustment is too large and it is easy to pinch passengers

Embodiment 1

[0036] Such as figure 1 As shown, this embodiment relates to a method for identifying the maximum current of a platform door motor under wind pressure under the influence of obstruction. , do not make the closing thrust of the platform door exceed the standard due to the adjustment of the working power of the motor, and avoid the excessive clamping force caused by the closing of the platform door, which will cause pinching injuries to passengers. The method for identifying the maximum current of the platform door motor under wind pressure includes the following steps:

[0037] Step S1: Turn on the current loop of the motor. The initial value of the current loop current is a mA (milliampere), usually set a=100mA, and the motor enters the torque mode by turning on the current loop of the motor. After the current loop is turned on, judge whether the motor starts normally. The normal start of the motor means that the output shaft (rotor) of the motor can rotate. Otherwise, it is ...

Embodiment 2

[0052] Such as figure 2 As shown, this embodiment proposes a platform door control method based on Embodiment 1 to deal with the solution to the situation that the platform door is blocked by wind pressure and other factors, including the following steps:

[0053] Step S4: According to Embodiment 1, the maximum allowable operating current I of the motor is obtained max Finally, control the motor to run normally, so that the platform door can be closed according to the door-closing stroke plan under the drive of the motor. The door-closing stroke plan of the platform door is as follows: image 3 As shown, this figure is also a specific example of the working principle of the motor when the platform door is normally closed, image 3 The screen door in the platform is also a kind of platform door. In the figure, the abscissa represents the time (seconds), correspondingly, it can also represent the displacement of the platform door, and the acceleration, constant speed, deceler...

Abstract

The invention relates to a platform gate motor maximum current recognition method under wind pressure and a platform gate control method. The platform gate motor maximum current recognition method under the wind pressure comprises the following steps that firstly, a current ring is started, whether a motor is normally started or not is judged, and if start is normal, the next step is conducted; secondly, the current of the current ring is gradually increased, whether the motor is normally started or not is judged, if the motor is normally started, the next step is conducted, and if the motor is not normally started, the current of the current ring is continuously increased; and thirdly, according to the current set current ring current during normal start of the motor, the allowed runningmaximum current of the motor is calculated according to the corresponding formula. By means of the platform gate motor maximum current recognition method under the wind pressure and the platform gatecontrol method, the motor allowed running maximum current under the situation of platform gate hindering due to the wind pressure and other factors can be well calculated, the platform gate control method is achieved, accordingly, the wind pressure is overcome, and a platform gate can be safely and completely opened and closed; and meanwhile, the situation that clamping force generated during platform gate closing is excessive when the current is increased to be excessive is avoided, and passengers are prevented from being mistakenly hurt.

Description

technical field [0001] The invention relates to the technical field of subway platform door control, in particular to a method for identifying the maximum current of a platform door motor under wind pressure and a method for controlling the platform door. Background technique [0002] The subway has become an important means of transportation for citizens. Among them, the platform door plays the role of isolating passengers from the subway / subway track, which greatly guarantees the safety of passengers. During the daily normal use of the platform door, there will be potential safety hazards caused by external interference. External interference mainly includes interference from foreign objects, geographical factors such as earthquakes, and wind pressure interference. Wind pressure is usually caused by tunnel piston wind. Wind pressure interference is A common distraction. When the subway increases the traffic density and gaps in order to increase the passenger carrying capa...
