Abstract

An elevator test operation apparatus for a multi-floor service elevator comprises a digital computer for processing an elevator control signal. The digital computer is provided with means for storing an elevator operation control program, and interface means for transferring a signal from an elevator control system to the digital computer or transferring a signal from the digital computer to the elevator control system, thereby to process the signal from the elevator control system in accordance with said elevator operation control program. The elevator test operation system further comprises means operated by maintenance personnel in a test operation and generating test signals such as a command for establishing an elevator car weight and a command for shortening a period of time when an elevator door is opened, and interface means for supplying those test signals to the digital computer, wherein the digital computer further comprises means for storing various programs for shortening the opening time of the elevator door during test operation and for establishing the elevator car weight, and a test operation program thereby to execute the test operation program in accordance with the test operation signal.

Claims

1. An elevator test operation apparatus for a multi-floor service elevator, comprising:

a digital computer for processing a signal from an elevator control system in accordance with an elevator operation control program to operate said elevator;

first interface means for transferring the signal from said elevator control system to said digital computer; and

second interface means for transferring a signal from said digital computer to said elevator control system, wherein the improvement comprises test operation control means built into said digital computer for executing the test operation of said elevator, and means connected to said digital computer through detachable connector means for generating a test operation signal for actuating said test operation control means.

2. An elevator test operation apparatus according to claim 1, wherein said test operation control means comprises test operation program execution means for executing a test operation program in response to said test operation signal, and means for storing said test operation program.

3. An elevator test operation apparatus according to claim 2, wherein said test operation signal includes a plurality of kinds of test operation commands, and wherein said test operation program execution means includes means for executing a plurality of kinds of test operation programs corresponding to said plurality of test operation commands.

4. An elevator test operation apparatus according to claim 3, wherein said test operation signal is a coded signal, and wherein said test operation programs include programs for decoding said coded test operation signal and said test operation program execution means includes means for initiating the test operation program associated with each coded test operation signal.

5. An elevator test operation apparatus according to claim 2, wherein said elevator control signal processing digital computer includes means responsive to a timer interruption for first executing said elevator control program and thereafter to execute said test operation program.

6. An elevator test operation apparatus according to claim 1, wherein said test operation signal includes commands for changing time intervals in the operation of the elevator by said digital computer, and wherein said test operation control means includes means for changing said time intervals in accordance with said commands for changing time intervals.

7. An elevator test operation apparatus according to claim 6, wherein said commands for changing time intervals include a command for shortening a period of time when an elevator door is opened, and wherein said test operation control means includes means for shortening the period of time when the elevator door is opened in response to control by said digital computer.

8. An elevator test operation apparatus according to claim 1, wherein said test operation signal includes a command for establishing calls which will result in said digital computer causing the elevator to stop at a selected position, and wherein said test operation control means includes means for establishing such calls in accordance with said command for establishing calls.

9. An elevator test operation apparatus according to claim 1, wherein said test operation signal includes a command for canceling set calls which would have resulted in said digital computer causing the elevator to stop at a selected position, and wherein said test operation control means includes means for canceling such set calls in accordance with said command for canceling set calls.

10. An elevator test operation apparatus according to claim 1, wherein said test operation signal includes a command for sequentially establishing calls which will result in said digital computer causing the elevator to stop at successive selected positions, and wherein said test operation control means includes means for sequentially establishing such calls in accordance with said command for sequentially establishing calls.

11. An elevator test operation apparatus according to claim 1, wherein said test operation signal includes a command for establishing an elevator car weight which will result in said digital computer establishing the weight of the elevator car, and wherein said test operation control means includes means for establishing such an elevator car weight in accordance with said command for establishing an elevator car weight.

12. An elevator test operation apparatus according to claim 1, wherein said test operation signal is a coded signal which includes test codes for indicating the kinds of tests and test data for indicating specific contents of the test indicated by each test code.

13. An elevator test operation apparatus according to claim 1, wherein interface means for transferring said test operation signal to said elevator control signal processing digital computer is provided on the side of the elevator system.

14. An elevator test operation apparatus according to claim 1, wherein both said test operation control means and said test operation signal generator means are detachably interconnected by means of a detachable connector.

15. An elevator test operation apparatus according to claim 14, wherein said test operation control means includes means for determining that the function of said test operation signal generator means has stopped, and means responsive to said determining means for changing said test operation control condition to the usual operation.

16. An elevator test operation apparatus according to claim 15, wherein said determining means includes means for detecting that said test operation signal generator means has not generated any signal for a predetermined period of time.
