The invention relates to a distributed anti-skid control method and device for a railway vehicle. The method comprises the steps that: a speed sensor acquires wheel speed information; a control processor of an antiskid microcontroller obtains a first wheel speed and a second wheel speed; the control processor calculates a difference value between the second wheel speed and the first wheel speed and calculates the ratio of the difference value to a preset time interval to obtain the speed change rate of the first wheel; according to the difference value between the first wheel speed and a preset speed correction value, an equivalent vehicle speed at the current time is obtained; when a communication state is normal, the host processor acquires the wheel speeds of all wheels at the current time and determines the vehicle speed with the maximum numerical value; the control processor obtains a first wheel speed difference according to a difference value between the larger one of the vehicle speeds and the equivalent vehicle speed and the first wheel speed; and when the first wheel speed difference is larger than or equal to a first preset threshold value and/or the speed change rate issmaller than a second preset threshold value, an exhaust control signal is output.
本发明涉及一种铁道车辆用分布式防滑控制方法和装置,其中方法包括:速度传感器获取车轮速度信息;防滑微控制器的控制处理器获取第一车轮速度和第二车轮速度;控制处理器计算第二车轮速度和第一车轮速度的差值,并计算差值与预设时间间隔的比值,得到在第一车轮的速度变化率;根据第一车轮速度与预设速度修正值的差值,得到当前时间的当量车速;当通讯状态正常时,主机处理器获取当前时间所有车轮的车轮速度,并确定数值最大的车辆速度;控制处理器根据车辆速度和当量车速中较大的一个,与第一车轮速度的差值,得到第一车轮速度差;当第一车轮速度差大于或等于第一预设阈值和/或速度变化率小于第二预设阈值时,输出排风控制信号。
