JPH08310396A - Controller of temporary speed limit signal device - Google Patents

Abstract

PURPOSE: To detect abnormalities even during normal ATC driving or even during performing of temporary speed control by comparing the condition of an equipment targeted for control and the control output result prediction of a controller and outputting an alarm when the comparison result shows non-coincidence. CONSTITUTION: In a determining part 15, the condition of equipment targeted for control inputted by a control target equipment condition input part 14 is fetched into a control target equipment condition fetching part 41, and during performing of condition change determination, a change in the control target equipment condition is determined. The condition change determination is performed based on the control target equipment condition fetched from the control target equipment, the prediction of a control output result and existence determination information for determining the actual existence of its bit in the equipment and a determination result is created. For alarm information, a control target equipment in which a change occurs is calculated from the determination result and information is set. When the control target equipment condition is not coincident with the prediction of a control output result, alarm information is edited and the alarm information is outputted to the machine part of a controller in an alarm information output part 17.

Description

Detailed Description of the Invention

[0001]

The present invention relates to automatic train control (hereinafter referred to as A
A temporary speed limit signal device for temporarily limiting the speed of a train in operation.

[0002]

2. Description of the Related Art In a line section where ATC operation is performed, when it is judged that train operation at a normal control operation speed is dangerous due to construction of the line, rain, wind, earthquake, etc., this place is regarded as a speed limit section. The speed limit signal is output to the automatic train operation device by the manual operation of the operator. Regarding the method of outputting the temporary speed limit signal, the method described in Japanese Patent Application No. 56-17759 has been proposed.

[0003]

In order to set the temporary speed limit signal, the speed limit signal is actually output to ensure that
Controlling the train to a safe speed is essential.
Therefore, it is necessary to have a method for determining whether or not an appropriate temporary speed limit signal is actually output and is actually reflected in the speed control of the train. However, although Japanese Patent Application No. 56-17759 describes a method of outputting a temporary speed limiting signal, it does not describe anything regarding safety.

[0004]

[Means for Solving the Problem] The state of the controlled equipment,
The control output result prediction state of the control device is compared, and if the comparison results do not match, an alarm is output. In addition, after the alarm is output, the control output result prediction is edited so as to match the control target equipment state, and the same alarm is not continuously output.

[0005]

Since the state of the equipment to be controlled and the state of the control output result prediction of the control device are constantly compared, an abnormality occurs even during normal ATC operation or temporary speed control. Can be detected.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a temporary speed limiting signal device according to an embodiment of the present invention. Reference numeral 11 is a control information input unit that takes in information for controlling the equipment to be controlled into the control device, 12
Is a control pattern creation unit that creates information to be controlled and output to the controlled equipment when the control information is input, 13 is a control information output unit that outputs control contents to the controlled equipment, and 14 is a state of the controlled equipment, The control target equipment state input unit 15 to be taken into the control device collates and determines whether the state of the control target equipment and the control output result prediction state of the control device match, and if they do not match, the alarm information is edited Part, 16
Is a control output result prediction creation unit that creates a control output result prediction when a control pattern is created and when the state of the controlled object equipment and the control output result prediction state do not match.
An alarm information output unit 7 outputs the alarm edited by the determination unit.

When the control information of the equipment to be controlled is input from the control information input unit 11, the control pattern creating unit 12 creates a control pattern for the equipment to be controlled.

The control pattern created in 12 is output to the equipment to be controlled by the control information output unit 13. Also, 12
The control output result prediction creating unit 16 creates a control output result prediction on the basis of the control pattern created in.

FIG. 2 is an explanatory diagram when the control output result prediction is created from the control pattern. The control pattern information 21 created by the control pattern creation unit 12 is bit-inverted, and a control output result prediction 22 is created as information for all the equipment to be controlled. This is the control pattern information, where the bit is "0" is "set", the bit is "1" is "unset", and the control output result prediction is "1" is "set". This is because the state where the bit is “0” is defined as “unset”.

The control output result prediction is based on the state of the controlled object equipment input from the controlled object equipment state input section 14 and the determination section 1
Whether or not they match is determined in 5, and even if they do not match, they are created.

FIG. 3 is an explanatory view of the control output result prediction creation in the case where the control target equipment state and the control output result prediction state do not match. When the control target equipment state 31 and the control output result prediction 32 do not match, the relevant bit of the control output result prediction is adjusted to the state of the control target equipment.

FIG. 4 is a flow chart for detecting the state change of the equipment to be controlled, and FIG. 5 is an explanatory diagram of the state change determination part. In the determination unit 15, the control target equipment state input by the control target equipment state input unit 14 is fetched into 41, and the state change determination 4
In step 2, it is determined whether or not there is a change in the controlled equipment condition. The state change judgment is taken from the controlled equipment,
The control target equipment state 51, the control output result prediction 52, and the bit thereof are determined by the presence determination information 53 that determines whether or not the equipment actually exists, and a determination result 54 is created. The information creation method is as follows. Where 51,5
The state of the bit of 2 is the same as that of the control prediction state creation unit described above. In 53, the state where the bit is "1" is "presence" of the equipment, and the state where the bit is "0" is "absence" of the equipment. The controlled object equipment state information 51 and the control output result prediction 52 are EOR-operated for each corresponding bit. Next, when the operation result is ANDed with the information 53 for determining whether or not the equipment exists, only the bit where the equipment exists and the control target equipment state has changed becomes “1”, and the change occurs. It is possible to determine the equipment to be controlled that had a problem. The calculation result is the determination result 54. When there is a change in the determination result, the alarm information 43 is set.
In the alarm information, the control target equipment that has changed from the determination result 54 is calculated, and the information is set. When the controlled object equipment state and the control output result prediction do not match, the alarm information is edited, and the alarm information output unit 17 outputs the alarm information to the man-machine unit of the control device. Further, as described above, the control output result prediction creating unit 16 creates the control output result prediction in accordance with the control target equipment state. The same alarm can be output only once by matching the control target equipment state information with the control output result prediction.

[0013]

[Effects of the Invention] Since the state of the equipment to be controlled is monitored regardless of the normal ATC operation and the operation with the temporary speed control, the abnormality can be detected promptly. In addition, since an alarm is output only once when an abnormality is detected, duplication of the same information can be prevented.
