2. Description of the Related Art In general, when an internal load of a car is 80% or more of a rated load, an elevator does not respond to a hall call at a landing on each floor, but only to a car call. That is, the packed lights provided at the landings are turned on to indicate that the car is full and to pass through the landings on each floor.

[0003] Further, in an elevator in which the group management control is performed, if there is a car in which the load in the car exceeds a certain reference value, the car is prevented from responding to the hall call, and the load in the car is reduced. Another car below a certain standard value is made to respond to the hall call. As described above, whether or not to respond to the hall call is determined on the elevator side based on the congestion degree of the car.

However, in such a conventional apparatus, even if the passengers at the landing desire to use an elevator with low congestion, the information is not transmitted to the landing. For this reason, when the elevator is opened in response to the hall call at the landing, the congestion status in the car is first known. Then, when the inside of the car is congested, even if the door is opened in response to the hall call, the passenger does not get into the car and waits for a car of low congestion to respond.

[0005] For this reason, even though the passengers at the landing do not get into the car, the car responds to the hall call, and the driving efficiency is deteriorated. Also, after answering the hall call, the passenger must press the hall call again and wait for the car to answer. Therefore, it is desired that the passengers at the landing can select a car according to the degree of congestion of the car.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an elevator control device which displays the congestion degree in an elevator car at a landing and allows a passenger to select a car according to the car congestion degree.

In FIG. 1, a call button 7 is provided at the landing on each floor, and a hall call input from the call button 7 is input to a call registration control unit 2 in the elevator control panel 1. The call registration control unit 2 registers the hall call input from the button 7 and inputs the hall call to the group management control device 12.

In the group management controller 12, a plurality of hoistways 8
Among the plurality of cars 9 existing in the car, a registered hall call is determined to be assigned to any car, and the result is output to the operation control unit 5. The operation control unit 5 performs operation control so that the car 9 assigned by the group management control device 12 responds to the hall call.

The car 9 is provided with load detecting means 10 for detecting the load in the car. The load in the car detected by the load detecting means 10 is inputted to the congestion degree recognizing means 4 in the elevator control panel 1. Is done. The congestion degree recognition means 4 determines the congestion degree of the car 9 based on the load in the car, and the congestion degree is displayed and output on the congestion degree display device 6 attached to the landing. Thus, the congestion degree of the car 9 assigned is displayed on the congestion degree display device 6 provided on each floor after the car assignment is determined.

The passenger determines from the congestion degree displayed on the congestion degree display device 6 whether or not to get on the car 9. If the passenger judges that he or she will not get on the car 9, the car 9
Will be canceled. The cancellation is performed by pressing the call button 7 again, and a cancellation signal is input to the call cancellation control unit 3.

When a cancel operation of a hall call is input from the call button 7 in the call canceling control unit 3, the registered hall call is canceled, and the fact is notified to the group management control unit 12.
