Problems solved by technology
[0003] Due to the lack of technical support, when people are trapped, the trapped people cannot be comforted in time, the elevators are sealed, and some even have no mobile phone signal, so they cannot get in touch with the outside world.

Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0035] see figure 1 , the present invention provides a kind of technical scheme: elevator trapped people alarm algorithm, comprises the following steps:
[0036] S1: Periodically read the motion sensor data installed on the car door, and calculate the horizontal and vertical motion data of the car door;
[0037] S2: Live sensors are arranged in the car to monitor whether there are people in real time and keep corresponding signal information;
[0038] S3: When th...

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.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator trapped alarm algorithm. Background technique [0002] At present, although domestic elevators are implementing a five-party intercom system, because all parties are working manually, there are often situations where people are trapped but cannot be connected, especially when a trapped person accident occurs at night. many. Some elevators do not have a five-party intercom system or are just a decoration. [0003] Due to the lack of technical support, when people are trapped, the trapped people cannot be appeased in time, the elevators are airtight, and some even have no mobile phone signal, so they cannot get in touch with the outside world. Incidents that caused trapped people to panic and irrationally save themselves and lead to secondary accidents also occurred, especially the psychological disorders and trauma caused by children being trapped are even more dif...
