The invention discloses an elevator person trapping alarm algorithm. The elevator person trapping alarm algorithm comprises the following steps that 1, data of a motion sensor mounted on a car door are periodically read, and transverse and vertical motion data of the car door are calculated; 2, a living body sensor is arranged in a car, whether a person exists or not is monitored in real time, andcorresponding signal information is kept; and 3, when someone is in the car, the car door is closed, a timer is started, when the car starts moving, the timer is stopped and reset, if the timing process of the timer exceeds a set value, an alarm triggering signal is generated, and alarm is started. The algorithm is simple, and a complex computing system is not needed; the algorithm operates independently, is not affected by elevator faults, does not interfere with elevator operation, and is safer; one sensor is adopted to calculate the car operating state and the car door operating state at the same time, so that the structure is simpler, and the cost is lower; and unattended guard is achieved, and automatic calculation and automatic alarm are realized.
本发明公开了电梯困人报警算法,包括以下步骤:S1:周期读取轿门上安装的运动传感器数据,计算轿门横向和竖向运动数据;S2:轿厢内布置活体传感器,实时监测是否有人,并保持对应的信号信息;S3:当轿厢内有人时,轿门关闭则启动计时器,轿厢开始运动时停止计时器并清零,计时器计时过程超过设定值产生报警触发信号,启动报警,本发明算法简单,无需复杂的计算系统;独立运行,不会受到电梯故障影响,也不会干扰电梯运行,更安全;采用一个传感器同时计算轿厢运行状态和轿门运行状态,结构更简洁,成本更低;无需人员值守,自动计算自动报警。
