The monitoring center 3 only receives the transmitted data.

An object of the present invention is to solve such a problem, and it is an object of the present invention to allow a monitoring center to perform data analysis in many aspects.

[0009]

The present invention for achieving the above object is as follows. (1) A data collection unit that collects data from equipment added to the facility, and a computer that stores and processes data from the data collection unit and couples the data to a communication network.
In a facility monitoring system including a system and a monitoring center connected to the communication network and remotely installed to monitor data, a data collection condition in the data collection unit is input to the monitoring center and the communication network is A facility monitoring system comprising: a condition input unit for transmitting; and a condition setting unit for setting data collection conditions from the condition input unit in the computer system or the data collection unit. (2) The equipment monitoring system according to (1), wherein the communication line network is an Internet line. (3) The data collection condition is characterized by non-execution of execution of alarm monitoring generated on the facility side, upper and lower limit values of data for the device as conditions for generating an alarm, and the like (1). Equipment monitoring system as described. (4) The equipment monitoring system according to (1), wherein the condition input unit includes a security unit that changes a condition that can be input according to a level of an operator. (5) The equipment monitoring system according to (1), wherein data collected according to conditions set in the condition setting unit is stored in a database in the computer system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration block diagram showing the concept of the present invention. In this figure, components having the same reference numerals as those shown in FIG. 2 have the same functions, and therefore detailed description is omitted.

The present invention provides a condition input unit 31 for arbitrarily inputting conditions for data collection to the data collection unit 1 in the monitoring center 3, and a communication line L from the condition input unit 31.
And a condition setting unit 22 for setting the conditions via the control unit.

According to such a configuration, the monitoring center 3
In the case of monitoring data transmitted via the communication line network L and changing the setting of this data and observing the transition state of the data, install it as a man-machine interface. In a certain condition input unit 31,
What is necessary is just to input a new condition.

After inputting the condition, the condition is transmitted to the condition setting section 22 of the computer system 2 via the communication line network L such as the Internet line or public telephone line.

Thereafter, the data collection unit 1 sets the devices d1, d2, and d2 in accordance with the conditions set in the condition setting unit 22.
, Dn are changed and set, and data collection is started under these conditions.

The conditions to be set and transmitted from the monitoring center 3 include the non-execution of alarm monitoring generated on the equipment side and various devices d1 and d as conditions for generating an alarm.
, Dn, the upper and lower limits of data, and the like.

As a result, in the monitoring center 3, data according to the new data collection conditions is transmitted, and by analyzing the data, it is possible to perform data analysis from a different aspect.

A security means may be provided so that several levels of passwords are set in the condition input unit 31 of the monitoring center 3 so that the input of data collection conditions can be changed according to the level of the operator.

Although FIG. 1 shows an example in which the condition setting unit 22 is installed in the computer system 2, it may be installed in the data collection unit 1.

The data collected according to the conditions set in the condition setting unit 22 may be stored in the database DB2 in the computer system 2, processed by the data processing unit 21, and output.

[0020]

According to the first, second, and third aspects of the present invention, data collection conditions are specified from a remote monitoring center to a computer system or a data collection unit via a communication line such as the Internet. Since the data can be set, the data analysis can be easily performed in many aspects in the monitoring center, and the data collection conditions can be dynamically changed. According to the fourth aspect of the present invention, the condition that can be input is changed according to the level of the operator, so that the security function can be improved. According to the fifth aspect of the present invention, the data collected according to the conditions set in the condition setting unit is stored in the database in the computer system. Therefore, the computer system 1 processes and outputs these data. Can be.
