[0002] At present, during the operation of the elevator, after the car is leveled, the door-opening time of the car has nothing to do with whether there are passengers in the car. The door-opening time of the car is usually preset by the elevator operation program, so that passengers calling on other floors wait If the time is too long, the passenger carrying efficiency of the elevator will be reduced and the operating cost of the elevator will be increased.

Embodiment Construction
[0013] like figure 1 As shown, the present invention automatically adjusts the method for elevator car door opening maintenance time to comprise the following steps:
[0014] Step 1. Preset the door-opening time from the car to the destination floor through the elevator control system. When the car reaches the destination floor along the running direction, use the car load sensor to detect the car load. When the car has a load, the car will The car opens the door according to the preset door opening holding time. When the car is empty, go to step 2;
[0015] Step 2. The elevator control system senses the call request in the car. When there is a call request signal, the car opens the door according to the preset door opening holding time. When there is no call request signal, perform step 3;
[0016] Step 3. The elevator control system senses whether there are passengers entering or leaving the car through the light curtain of the car door. When a passenger enters or exits the...

The invention discloses a method for adjusting the door opening retention time of an elevator car automatically. The method comprises the steps that firstly, the door opening retention time of the elevator car to the target storey is preset through an elevator control system; when the elevator car reaches the target storey, the load of the elevator car is detected by means of an elevator car weighing sensor; the elevator control system induces a call request in the elevator car and induces whether a passenger enters or comes out of the elevator car through an elevator car door light curtain; and when a load and a call request signal exist in the elevator car and a passenger enters or comes out of the elevator car, a door of the elevator car is opened according to the preset door opening retention time, otherwise, the elevator control system controls the door of the elevator car to be closed directly, and the door of the elevator car does not need to be opened according to the preset door opening retention time. By the adoption of the method, the defects of the door opening retention time of a traditional elevator car are overcome, the waiting time of passengers which call for an elevator and located on other storeys is shortened, the passenger carrying efficiency of the elevator is improved, and the operation cost of the elevator is reduced.
Description
technical field [0001] The invention relates to a method for automatically adjusting the time for keeping the door of an elevator car open. Background technique [0002] At present, during the operation of the elevator, after the car is leveled, the door-opening time of the car has nothing to do with whether there are passengers in the car. The door-opening time of the car is usually preset by the elevator operation program, so that passengers calling on other floors wait If the time is too long, the passenger carrying efficiency of the elevator will be reduced and the operating cost of the elevator will be increased. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for automatically adjusting the door-opening time of the elevator car. This method overcomes the defect of the traditional elevator car door-opening time, reduces the waiting time of passengers calling for elevators on other floors, and improv...
