    • PURPOSE:To economize time and labor by evaluating the service performance for the specification as the initial values in the elevator installation planning and assisting the optimum installation plan preparation for an elevator in which estimation through the repetition of the improvement and evaluation for the specification until the evaluation achieves the aims. CONSTITUTION:A calculation part 1 receives the aims of the traffic demand for an elevator and the service performance obtained by the elevator from FD drives 3 and 4 in the installation designing of the elevator, and sets the specification of the elevator as initial values, and evaluates the service performance by the elevator specification as the initial values, and carries out estimation in which the improvement and evaluation for the elevator specification as the initial values are repeated until the evaluation reaches the aims. The elevator installation plan in the combination of the elevator specification for achieving the aims and the service performance as the result of the estimation is outputted from an output device 5 and a printer 6. Accordingly, the optimum elevator installation plan preparation is assisted, and time and labor can be economized.

    • PURPOSE:To keep off the extreme worsening of efficiency due to overregulation for a degree of congestion in a cage by assigning a service elevator on the basis of an allowable value to the degree of congestion in the cage in adding an allowable value of latency to the former. CONSTITUTION:A user sets an allowable value of a degree of a congestion in a cage and that of latency to a group-control governing system 2 with an input unit 1. If it is difficult for this setting, a degree of significance to the degree of congestion in the cage is inputted through an intelligence part 2-1, and a fuzzy inference taking account of traffic situations is applied to the allowable value of congestion in the cage and the allowable value of the latency, converting them and these values are set. Then, an assigning part 2-2 performs its assignment according to the precedence of three stages, namely, the elevator coming in earliest in two allowable values, the second one of the lowest congestion in the cage satisfying the latency allowable value and the third one coming in earliest. Thus, the extreme worsening of efficiency due to overregulation for the degree of congestion in the case can be prevented from occurring.

    • PURPOSE:To perform the quick trouble diagnosis in a wide range on the elevator control device side by providing an arithmetic circuit generating the door opening/closing continuous position signal based on detected signals of the opening/closing action direction and opening/closing speed and a trouble judging circuit in an elevator and a door opening/closing control device. CONSTITUTION:An opening/closing direction detecting circuit c201 and a speed detecting circuit c202 processing detected signals of the opening/closing action direction and opening/closing direction from the opening/closing detector c51 in a door opening/closing drive device c50 are provided in a door opening/closing control device c20, and a trouble judging circuit judging the presence of the trouble of the door opening/closing control device c20 based on the continuous position signal and outputting the signal to stop the opening/closing control of a door is provided in an elevator control device. Actions of the door opening/ closing control device c20 and the drive device c50 for the command from the elevator control device side can be checked.
