DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control system for a remote monitoring system that provides services such as security based on information from a remote monitoring device installed at a remote location.

[Conventional technology]

FIG. 2 is a block diagram showing the configuration of a conventional remote monitoring system. In FIG. 2, 7a and 7b are remote monitors having a monitoring circuit for obtaining monitoring information by detecting the operation of the monitoring sensors, in which a plurality of monitoring sensors for performing various types of monitoring are connected through respective terminals. It is a device.

The remote monitoring device 7a includes a fire sensor 2 as a monitoring sensor.
a and the intrusion sensor 2b, and a signal input terminal 4a and a signal line 3b connected to the fire sensor 2a via the signal line 3a.
A signal input terminal 4 connected to the intrusion sensor 2b via
The monitoring circuit 1a has a monitoring circuit 1b. The remote monitoring device 7b includes a fire sensor 2C, an intrusion sensor 2d, a signal input terminal 4C connected to the fire sensor 2C via a signal line 3C, and a signal input terminal 4C connected to the intrusion sensor 2d via a signal line 3d. The monitoring circuit 1b has a terminal 4d.

The fire sensors 2a and 2c are used to detect, for example, a fire in a building, and the intrusion sensors 2b and 2d are used to detect, for example, a person's intrusion. 8 is an information processing center where monitoring information from the remote monitoring devices 7a and 7b installed in various places is collected, and this information processing center 8 is equipped with a host computer 6 that performs predetermined information processing based on the monitoring information. ing. Signal lines 5a and 5b connect the host computer 6 and the remote monitoring devices 7a and 7b, respectively.

Next, the operation will be explained.

For example, the monitoring circuit 1a of the remote monitoring device 7a includes the sensor 2
The operating states of a and 2b are detected by signal lines 3a and 3b connected to terminals 4a and 4b.

When the operation of the sensors 2a, 2b is detected, the remote monitoring device 7a sends information on the sensor operation (monitoring information) to the host computer 6 via the signal line 5a.

This information includes the number of the terminal that detected the operating state of the remote monitoring device 7a, for example, if terminal 4a is in the operating state, code 1, and if terminal 4b is in the operating state:
If it becomes 1, information such as code 2 is included and 1
Based on this code, the host computer 6 stores the information sent from the monitoring devices 7a and 7b in the computer's memory until it is immediately notified to a person (online processing) or until a person requests the information. It is determined from the terminal code whether the process is to be saved (batch process) and the corresponding process is performed.

By the way, for example, in a remote monitoring device for LPG meter reading, the sensor connection terminals include a cylinder exchange reset terminal, an automatic switching valve device terminal, a gas cutoff valve monitor terminal, a fire sensor terminal, an intrusion sensor terminal, and an emergency sensor terminal. etc., so the user connects each sensor to a designated terminal.

(Problem to be Solved by the Invention) Since the conventional remote monitoring system is configured for the above-mentioned purposes, there is a problem in that sensors that are not set in the system (such as a rice bin sensor or a kerosene sensor) cannot be used. For example, if a kerosene sensor is connected to a fire sensor terminal, the remote monitoring device will consider the information sent when the kerosene sensor is activated as fire sensor information, and the terminal code for the fire sensor will be sent to the host computer. On the host computer side, processing is performed assuming that a fire has occurred.

This invention was made in order to solve the above-mentioned problems, and even if the number of terminals to which monitoring sensors are connected is limited, it is possible to freely select the type of monitoring sensor to be set on the system. The object of the present invention is to provide a control method for a remote monitoring system that can expand the range of use and perform various types of information processing.

[Means to solve the problem]

In the control method of the remote monitoring system according to the present invention, the type of monitoring sensor is included as a type code, and the type code is set for each terminal, and when the monitoring sensor connected to the corresponding terminal operates, Remote monitoring devices 7a, 7
b includes the relevant type code in the relevant monitoring information, sends the monitoring information including the type code to the host computer 6, and causes the information processing to be performed based on the type code.

(Function) For example, the monitoring sensor (fire sensor 2
When a) is activated, the remote monitoring device 7a includes a type code indicating the type of the monitoring sensor in the monitoring information by the monitoring sensor, and sends the monitoring information including the type code to the host computer 6. The host computer 6 performs information processing based on the type code in the sent monitoring information.

d is connected to the fire sensor 2d via a signal line 3d.

Note that the kerosene sensor 2C detects, for example, the amount of kerosene in the kerosene tank.

Next, the operation will be explained.

When using a fire sensor as the monitoring sensor 2a, an intrusion sensor as the fire sensor 2b, a kerosene sensor as the monitoring sensor 2C, and a fire sensor as the monitoring sensor 2d, the type code "
01'', the type code ``02'' is set to the terminal 14b, the type code ``03'' is set to the terminal 14C of the monitoring circuit 1b in the remote monitoring device 7b, and the type code ``01'' is set to the terminal 14d.

For example, when the fire sensor 2a operates, the type code "01" is also transmitted from the remote monitoring device 7a to the sensor operation information (
(monitoring information) and sends it to the host computer 6.

The host computer 6 determines that it is a fire by looking at the type code "01" in this sensor operation information. In addition, even if the terminals are located at the same position as viewed from the monitoring circuit, if the kerosene sensor 2C of the remote monitoring device 7b operates, the terminal 14G
Since the type code "03" set in is sent to the host computer 6, the host computer 6 detects the amount of kerosene and performs information processing accordingly.

In the above embodiment, only the type of monitoring sensor is set as the code, but if the code is set to 3 digits, the last two digits are the type of monitoring sensor, and the first digit is the online batch specification on the host computer. , Even if the same type of monitoring sensor is used, the processing can be changed.

(Effects of the Invention) As described above, according to the present invention, the type of the monitoring sensor is provided as a type code, the type code is set for each terminal to which the monitoring sensor is connected, and the monitoring information including the type code is hosted on the host. Since the information is sent to the computer and processed based on the type code, even if the number of terminals is limited, the type of monitoring sensor set on the system can be freely selected. At least many types of monitoring sensors can be used, thereby expanding the scope of use and allowing various types of information processing to be performed.
