JPS6051041A - Trouble deciding system by deciding pattern - Google Patents

Abstract

PURPOSE:To enable to grasp the cause of a trouble easily, when inputted trouble information is different from the state of stored trouble information by sending this to a deciding section and making decision according to a deciding pattern of a deciding pattern generating section. CONSTITUTION:Trouble information detected from various apparatus is inputted to a status change detecting section 32. The section 32 compares the state of trouble information stored in a memory section 33 with the state of trouble information inputted this time. When the states are different, it is judged that there is change of the state, and outputted to a deciding section 34, and at the same time, trouble information stored in the memory section 33 is replaced with the state of inputted trouble information. When data are inputted from the detecting section 32, the deciding section 34 reads a deciding pattern from a deciding pattern generating section 35 and makes decision using inputted trouble information. When function is stopped as the result of decision, the result of decision is outputted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a remote monitoring and control system that collects and monitors failure information of each device such as a communication terminal station and a relay station in a communication system. Regarding the method.

Conventionally, in this type of failure monitoring, failure information detected by various devices is transmitted to a center that monitors all of the various devices by a remote monitoring and control device installed at the same location, and then the information is transmitted to a center that monitors all of the various devices. Received by the supervisory control device. In this remote monitoring and control device, received various failure information is displayed in Ll:1 (individual display) or 1:N by lamp display, etc.
The failure of each device was determined by the operator of the device by looking at the display (selective display by location).

As this failure information, for example, a single relay station having two active and standby transmitters/receivers sends a plurality of pieces of failure information about each transmitter, receiver, power supply, etc. to the monitoring device. This failure information is divided into combinations of those that are affected by other devices and those that are not, and those that are and are not affected by other devices, depending on the cause of the failure, and those that are not affected by other devices. can determine a failure based on the failure information of the device itself, but if the device is affected by another device, it cannot be determined whether the device has failed unless the failure state of that device is known. For example, the failure information of the receiving system of the relay station is a hierarchical connection system that completely reflects the influence of the previous relay station, so if you do not understand the connection relationship, you will make incorrect decisions. . Therefore, in systems where a large number of devices are connected, it has become impossible for the operator to make decisions.

The purpose of the invention is to solve all of these problems and to create a failure determination method using a determination pattern that facilitates failure determination by combining these various types of failure information and using a determination pattern that aggregates the failure information of each device. VC to provide
be.

The failure determination method based on determination patterns of the present invention includes a determination pattern forming means for forming a determination pattern for each device by combining various types of failure information outputted from each device in advance in terms of malfunction of each device; The system includes a pattern matching means that inputs a pattern, matches the various types of fault information for each of the devices, and outputs aggregated virtual fault information.

The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a pattern diagram showing a specific example of the judgment pattern in the embodiment of the present invention.
Saturday 2) shows the judgment pattern of failure information of a wireless relay station with a transmitter and receiver - In the figure, 1 to 9 are various failure information sent from this relay station to the monitoring device, io ~ 1
8 is the AND (22, 25, 2
7, 28), 0 几 (20゜21, 23.24.26
) shows various types of virtual fault information created based on generation conditions. These correspondence relationships are shown in Table 1 below.

Table 1 This table actually shows failure information, but tentatively shows virtual failure information, and R
X is the receiver, TX is the transmitter, and PS is the power supply.

TP is the transmission power amplification section, and ADJ is the previous stage opposite station.

TR indicates all transmitting and receiving sections. For example, the RXI virtual failure information 10 is No.1. RX failure information 1, NQl, P
The virtual failure information 16 of R and ADJ) failure information 9 and virtual failure information 15 of UX 12 are formed by 0R26, and it is determined that the reception system failure is due to a failure in the previous opposite station or a failure in both reception systems. It should be noted that the failure of the preceding opposite station is determined based on the simultaneous failure of the working and standby power supply systems.

This determination pattern is for determining all the failures of this device by consolidating nine types of failure information 1 to 9 into three types of virtual failure information 16 to 18 (reception failure, transmission failure, and transmission/reception failure).

FIG. 2 is a block diagram of an embodiment of the present invention, which includes a state change detection section 32 that inputs fault information from an input terminal 31 and detects state changes, and a storage section 33 that stores the states of various input fault information. , a determining section 34 that detects a state change, performs a failure determination, and outputs the determination result from an output terminal 36, and a determination pattern generating section 35.

Failure information detected from various devices is sent to the state change detection unit 3.
2 Tlc is input, and the state change detection section 32 compares the state of the fault information stored in the storage section 33 with the state of the fault information input this time, and if the states are different, it is determined that there is a state change. It makes a judgment and outputs it to the judgment unit 34, and also replaces the failure information stored in the storage unit 33 with the state of the input failure information. In the determination unit 34, when there is data input from the state change detection unit 32, the determination pattern generation unit 3
5, all judgment patterns are read and all input failure information is used to perform judgment processing. As a result of this judgment process, if the function has stopped, the judgment result is output.

This judgment pattern generating section 35 creates a combination of judgment patterns as shown in FIG. 1 for each device and outputs the corresponding judgment pattern according to the input device information. Determining which virtual failure information corresponds to As explained above, the present invention performs failure determination by patterning it from the perspective of malfunction of various devices, and even if different devices As long as the conditions leading to the above are the same, failure can be determined using the same determination pattern, and the cause of the failure can be easily determined.
