Title: Device for controlling door open of elevator
Inventor: IKEDA HIDEO
IPC: B66B5/02
Filed: 1988-03-11
Abstract: PURPOSE:To ensure the safety of riders while giving a sense of security to the riders by providing a failure judging means which makes the most of a signal for indicating a narrow door open range at the normal time of an elevator while making the most of a signal for indicating a wide door open range at the time of failure of the elevator. CONSTITUTION:Door zone detecting signals S6, S7 obtained from a door zone detecting switch 8 are detected as two different zones of a narrow range zone and a wide range zone by a door zone detecting portion 19, and the narrow range portion is outputted as S15 while outputting the wide range portion as S16. A door zone judging portion 20 selects either door zone of the input signals S15, S16 based on a failure signal S14 outputted from a failure detecting portion 18. That is, at normal times, no failure signal S14 is inputted and the signal S15 is selected limiting the door zone in a narrow range. At the time of failure, the signal S14 is inputted and the signal S16 is selected to spread the door zone to the large range. Thereby, the self-escapable zone of riders can be increased.

CONSTITUTION:Reception data (a) from a host device 409 is supplied to and stored in a page buffer 403a. After that, a CPU 401 checks whether or not a null buffer 403a exists, and when it is filled, a set signal (d) is sent from an input/output port 408a to an FF 408b. Thereby, set output is inverted at an inverter circuit 408c, and a busy signal is outputted to the device 409. The degree of vacancy of the buffer 403a is checked i.e. whether or not it approaches near-end. When no near-end state is detected, the CPU 401 continues the delivery of a reset signal (e) from the port 408a to the FF 408b. In such a way, the FF 408b remains reset, and the busy signal from the circuit 408c remains turned off, then, the data can be sent from the device 409 at the highest speed.
