sending the first prompt message to a hall door safety prompt device; and the hall door safety prompting device is used for sending a prompt according to the first prompting information so as to prompt that the hall door on the current floor is abnormally opened.
6. The elevator prompt control method according to claim 5, wherein the step of determining whether the elevator is abnormally opened according to the opening floor information and the car height comprises:
determining the height of an opening layer according to the opening layer information and preset layer height information;
calculating the height difference between the height of the opening layer and the height of the car;
and judging abnormal opening when the height difference is larger than a preset threshold value.
7. The elevator guidance control method according to claim 5, further comprising:
acquiring the opening state of the car door;
generating second prompt information when the car door opening state is abnormal;
sending the second prompt information to a car safety prompt device; and the car safety prompting device is used for sending a prompt according to the second prompting information so as to prompt the car door to be opened abnormally.
8. An elevator guidance control device, characterized in that the device comprises:
the first information acquisition module is used for acquiring the state of a hoistway door and the height of a lift car; the elevator hall door state comprises a hall door opening state and opening layer information;
the abnormal door opening judging module is used for judging whether the elevator car is abnormally opened or not according to the opening layer information and the height of the elevator car when the hoistway door is opened;
