Description

  The present invention relates to an elevator maintenance terminal apparatus suitable for use in changing a setting of various data by accessing a computer installed in a control panel.

  A computer used as an elevator control device is installed in the elevator control panel. Various data for controlling the operation of the elevator is set in the memory of the computer. The various data includes, for example, data relating to car load adjustment (balance control with car and counterweight), car travel pattern adjustment, car door adjustment, and the like.

  Usually, when changing the setting of these data, a portable terminal device called a “maintenance tool” is used. The maintenance staff connects the terminal device to a computer in the control panel, reads out the address of the data whose setting is to be changed, and inputs the data corresponding to the address.

  At that time, while connecting a measuring instrument to the computer and checking the waveform of the input data on the screen of the measuring instrument, if it is insufficient, the operation of inputting the data again and adjusting it is repeated.

Conventionally, regarding such a data setting change, there has been known one in which a monitor screen with a touch panel function is installed in a control panel and various data are input on the monitor screen (for example, Patent Document 1). reference).
