正常であるか否定かを知ることができる。[Prior art] An AC induction motor is used as a railway point machine.
Its mechanical output and torque are proportional to the square of the current. The output is transmitted to a branching device via a friction clutch. The purpose of this clutch is to protect the motor, not to apply a shock to the motor at the time of starting, and to make the motor run idle when an excessive load is applied. Therefore, by measuring the operating current of the motor, it is possible to know whether the operating state of the point machine is normal or not.

整備を行っている。For this reason, in the past, regular patrols were performed at night when train operation was interrupted, and the switch was operated by the manual switch,
The company measures current, measures conversion time, and performs maintenance such as close contact, lock adjustment, loosening of bolts and nuts, and lubrication to achieve the specified values.

Therefore, detecting a failure in advance is very important for normal operation of a train. By increasing the number of times, failures can be predicted in advance to some extent, but there are limitations.

The current information detected by the sensor 2 is amplified by an amplifier unit 5 and then filtered by a filter to remove noise, and then supplied to a microcomputer unit 7 via an A / D converter 6. . The microcomputer unit 7 captures and stores the data in the storage unit 7a, and stores and stores the peak value, the peak position, the average value, the operation time, and the number of operations of the current by the threshold value storage unit 7b and the comparison unit 7c and the operation pattern extraction unit 7d. Compare with threshold. The switch 9 sets an apparatus number, and the conversion section 8 converts an output signal from the microcomputer section into a format suitable for a transmission line.

る度に発生する。FIG. 3 shows measurement data obtained from a sensor, which is stored in a memory after A / D conversion. When a current is supplied to the motor, a starting current flows, and an initial peak appears. Thereafter, a substantially constant current flows, and a second peak appears immediately before the power is turned off. This is a characteristic when the point machine is operating normally and occurs each time the point machine changes.

FIG. 4 (c) shows how the transition time is extracted, and the time from the beginning to the end of the current flow is extracted. FIG. 4 (d) shows how the average current is extracted. After masking the hatched portion of the first peak from the beginning of the current flow, the average up to the end is taken as the average current.

Data extracted as shown in FIG. 4 is stored in a comparing unit 7c in a microcomputer unit 7 from a threshold storage unit 7b and an operation pattern extracting unit 7d. Is compared with the control limit pattern 7f. If the point machine has any signs of failure, there is some change in the extracted data. For example, when the sliding portion runs out of oil, the conversion time increases and the average time increases. For this reason,
If at least one of the parameters is out of the management limit, the result is transmitted to a central station (not shown) via the transmission means 7e. This allows the central office to constantly monitor the operating state, so that a failure can be detected in advance and optimal processing can be performed before the failure occurs.
