Abstract

PURPOSE:To improve the data collecting efficiency by setting the data collecting time point in response to the processing result of collection data. CONSTITUTION:Information collected by an error counter 2 of a part 10 to be monitored is sent to an NTT communication network 30 through the 1st communication control unit NCU 3. At a monitor control part 20, the information data is sent to the 2nd communication control unit NCU 6 through the network 30. A CPU 7 processes the received data and transmits a collection command signal. In other words, the data information received by a data receiving part 21 is checked by a data deciding part 22 as to whether it is an error data or not. If the error data is confirmed, a decision output part 23 outputs fault decision data. While a collecting cycle setting part 24 sets automatically and variably the data collecting cycle in response to the generating frequency of the error data. A data collection designating part 25 actuates the NCU 6 for each set collecting cycle to collect data.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a preventive maintenance data collection system, and more particularly to a remote preventive maintenance data collection device for collecting preventive maintenance data of computer systems located in remote locations.

B1 Overview of the Invention The present invention is a system that collects preventive maintenance data from monitored units located in remote locations into a computer at a maintenance center via a telephone line network, so that the collection time point can be set according to the collected data processing results. By doing so, data collection efficiency was improved.

BACKGROUND OF THE INVENTION Computer systems are provided with error counters for diagnosing equipment failures.

This error counter indicates the number of times the protection circuit operates, and is different from the monitoring alarm counter, which indicates the stoppage of external functions. Furthermore, from the standpoint of equipment, error counters are effective for determining equipment deterioration and failure analysis. For this reason, as a preventive maintenance data system for computer systems scattered over a wide area, a method is used in which error counter data is periodically collected from a maintenance center via a telephone line.

D2 Problem to be solved by the invention In order to effectively operate a system such as a preventive maintenance data system for computer systems that periodically collects data from a maintenance center through a telephone line, it is necessary to collect a large number of extremely rare error information. System J3 is required to collect data from managed computers. Furthermore, preventive maintenance data collection systems generally collect data at regular intervals, and as the number of target systems increases, the amount of data increases and the transmission time increases. Therefore, if a change occurs in the preventive maintenance data, it is important to shorten the data collection cycle, collect as much effective data as possible, and analyze and take countermeasures.

Means and operation for solving the E1 problem The present invention has the following features:
This was done in view of the problem mentioned above, and the maintenance data of the number of error counter operations of the monitored units, which are located in remote locations and are processed by computer systems, is sent to the maintenance center's computer station 1 through the telephone line network. In a system that collects data in a monitoring unit including , the next data collection point can be set according to the data processing of the collected data.

F. EXAMPLES The present invention will be specifically explained below using examples shown in FIGS. 1 and 2.

FIG. 1 shows the configuration of a preventive maintenance data collection system, in which 10 is a first computer system which is a monitored unit scattered in various places, and 20 is a monitor that monitors and controls the monitored unit 10 through a telephone line network 30. This is a second computer system which is a control unit.

The monitored unit 10 includes a first arithmetic processing unit 1. error counter 2
．． It is composed of a first communication control unit 3 connected to a telephone line network 30 and an input/output circuit 4 that connects these to a device 5 to be monitored.

The supervisory control section 20 is composed of a second communication control unit 6 connected to a telephone line network 30 and a second arithmetic processing section 7.

FIG. 2 shows the configuration of the second arithmetic processing section 7.
is a data receiving section, which receives data transmitted through the communication control unit 6.

22 is a data determination unit that determines whether or not there is error information in the received data. Reference numeral 23 denotes a judgment output section which operates and outputs a judgment signal if there is error information in the data. 24 is a collection cycle setting section, and the data determination section 22
The data collection cycle is set according to the determination result. 25
is a data collection command unit that transmits a data collection command at the cycle set by the collection cycle setting unit 24.

In the data collection device having the above configuration, the error counter 2 of the computer system of the monitored unit IO indicates the number of times the protection circuit of the monitored device 5 is operated due to, for example, noise mixed in the electronic circuit or deterioration of the element. Therefore, it is not an error that immediately deteriorates external functions. However, this data on the number of times the error printer 2 operates is useful for preventive maintenance. Also, it only works very rarely. As parts and circuits deteriorate, the number of protection operations increases, providing useful information for fault diagnosis.

Information from the error counter 2 of the monitored unit IO is sent to the telephone line network 30 through the first communication control unit 3. In the monitoring control section 20, information data is transmitted from the telephone line network 30 to the second communication control unit 6. The second arithmetic processing unit 7 processes the received data and transmits a collection command signal. That is, as shown in FIG. 2, the data information received by the data receiving section 21 is determined by the data determining section 22 whether or not it is error data. If the data is an error, the determination output section 23 operates and a failure diagnosis is performed. Further, the collection cycle setting unit 24 automatically sets the data collection cycle variably according to the number of occurrences of error data. In other words, if more errors occur, the data collection cycle is shortened to improve analysis accuracy.

The data collection command w-25 causes the communication control unit to operate and collect data every set collection cycle.

G4 Effects of the Invention The present invention is as described above, and by setting the next data collection cycle based on the error data processing result, it is possible to increase the number of computer systems that can be accommodated and managed, and to collect more data for degraded systems. This allows highly accurate data collection, and even if there are many target systems, it can be operated with a relatively small amount of data collection, and data volume and transmission time can be prevented from increasing.
