Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator maintenance device, and more particularly, to an elevator maintenance device suitable for an elevator that uses a microcomputer in the signal processing section of a %jr (x repeater).

[Background of the invention]

In general, an elevator system consists of a car that moves back and forth on each floor, a motor that drives the car, and a control panel that processes signals from each floor and inside the car to drive and control the motors. In addition, the control panel monitors the on/off status of the hall button and car call button, as well as the on/off status of each operating circuit.

It includes an information processing section that takes out an off signal, and a drive control section that performs controls related to driving the motor.

In order to operate this sophisticated elevator system safely, careful fc monitoring is required, and for this monitoring (IJ), maintenance staff must use a maintenance device consisting of a cathode ray tube (CRT) or printer, etc. It was connected to the information processing section of this maintenance equipment Y control panel and checked the signal Y of the information processing section.Also, in the event of a failure in the elevator system, the signal from the information processing section was also sent. Regardless of whether the failure σ9 occurred in the past or the present, the method of ``investigating the condition of the failure and the cause of the failure'' has been adopted.

By the way, the above-mentioned conventional maintenance device is configured to extract only the signals from the information processing section, so it has the disadvantage that it is not possible to see the signals from the drive control section related to the motor drive. Furthermore, even if the signals of the drive control section were taken out by another appropriate device, it would be difficult to read both signals using the same time chart. For this reason, it is impossible to quickly investigate a fault, especially when investigating a fault, and there is also the problem that this cannot be carried out completely even during normal monitoring.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to solve the problems of the prior art, to enable simultaneous management of the information processing section and the drive control section, and to reduce maintenance costs. An object of the present invention is to provide an elevator maintenance device that can improve the workability of elevators.

[Summary of the invention]

In order to achieve the above-mentioned objectives, the present invention inputs the signal of the information processing section and the signal of the drive control section through the input means, and simultaneously outputs the signal yc'rlt of the computer to an output device such as a printer. It is characterized in that it is designed to output pressure force.

It is stored in a predetermined form at a predetermined address in address area AH2 of M24.

In this way, the information processing unit 2 stores information in the RAM 24 at regular intervals.
Then, the keyboard input unit 36 is used to select the required data from the data stored in the R, AM 24 (there are several thousand pieces of stiffness data), and output the data. ? When instructed, the selected data is taken out from the RAM 24 in order to become a program stored in the engineering ROM 23, and the PIA 25, 26

The waveforms of CHI data to CH4 data stored in are displayed. In these waveforms, all the horizontal axes are the same time axis, so each waveform of the information processing unit 2 and drive control unit 3I7) is displayed in the same time chart on the display screen 41, and both data are directly Also, it can be compared continuously and check Y can be easily performed.

Here, the comparison of stiffness data will be explained with reference to the required parts of the specific examples shown in Figures 4 and 5.
Ru. SGI data is from left to right in the figure, bit 7 to bit O.
It consists of 8 bits, and its data is rlooo
This is olloJ. In this case, for example, 7th bit: A signal indicating the opening/closing state 2 of the elevator car door 6th bit: A travel command signal that gives a travel command to the elevator 5th bit: A deceleration command signal to give an elevator deceleration command Y 4th bit: Elevator Command to stop? The stop signal to be given is stipulated. Furthermore, the 7th bit to 0th bit in the SG4 data is a signal representing the operating state Y of the elevator car destination floor call registration device for the 8th floor to the 1st floor, and the recorded 804 data "00100010" shown in the figure is
indicates that call registration for the 2nd and 6th floors is being performed.

CH1 data to CH4 data represent the drive control system signal Y as described above, for example, CHI data: elevator car CI) acceleration/deceleration CH2 data: speed command voltage CH3 data: drive current CH4 data for accelerating and running the motor. : Defined as the braking current that applies the electric brake to slow down the motor.

In addition, 5GI-7, 5GI-6°8G1 in Fig. 5
-5,801-44! 7th bit in 5G1f-fiK, 6th bit, ! 5 bits, represents the 4th bit signal.

The elevator is configured so that a driving system signal is outputted by an information processing system signal button. According to the above example, when the calls for the elevator car destination floors (2nd floor and 6th floor) are registered, the car destination floor call registration signals 5G4-1 and 8G
A high level signal "1" indicating signal establishment is output to 4-5, and in response to this, the area elevator performs the door closing operation Y.
When the door is fully closed, the warpage confirmation device is activated and signal 8Gl is activated.
-7 becomes a high level signal "1" indicating signal establishment.

By outputting this signal rlJ, travel command signals 8G1-6 are output to the elevator, speed command voltage CH2 is applied, and drive current CH3 flows to the motor. As a result, the elevator accelerates and runs toward the second floor.

When the elevator approaches the second floor, deceleration command signal 5GI
-5 is output, and therefore the speed command voltage CH2 is lowered for deceleration, and a braking current is supplied to the motor by a signal CH4 corresponding to the voltage to decelerate the elevator. The elevator arrives at the second floor level-f
Then, a stop signal by signal 5G1-4 is output, and the elevator stops at the second floor.

The above is the operation during normal operation, and this operation is the fifth
This can be clearly understood by observing the waveforms shown in the figure.

Figure 6 shows C when a failure occurs during the operation shown in Figure 5.
It is an ILT cv display waveform diagram. In the figure, each waveform is shown when the signal 8G1-41, which is a stop signal, occurs early for some reason. According to this, the waveforms of the signal CHI and the signal CH2 are disturbed in synchronization with the generation of the signals 8G1-4, and it is determined that an abnormal state exists. In this case, it is possible to clearly determine whether the cause of the abnormal state is in the information processing system or the drive control system, and the causal relationship between the two. Therefore, conventionally, when investigating the cause of a failure, first, the failure phenomenon Y is inferred, the signal Y of the information processing system or drive control system that is presumed to be the cause is separately captured, and those signals are identified. This greatly simplifies the work of investigating the cause compared to the method in which the cause of the failure was determined by comparing the two.

In this way, in this embodiment, both the data of the information processing section and the data of the drive control section are input into the data calculation/control section, and the desired data from among these data is selected using the keyboard input device to output data to the printer, CRT, etc. Since the value of each data at the same time can be recorded on the same recording paper, and the value of each data can be displayed on the same display screen with the same time chart, various σ can be output by kneading. This allows for easy checking and improves work efficiency.

The keyboard input device can not only select data, but also set various setting values, issue operational commands for dummy operation, etc. Further, it is not necessary to have both a printer and a CRT; it is also possible to have only one printer and one CRT.

〔Effect of the invention〕

As described above, in this embodiment, data is input to the information processing section and the drive control section, and required data of this data is input. Since the information is output to the output device at the same time, the information processing section and the drive control section can be managed at the same time, which facilitates various checks and improves maintenance work efficiency.
