[0002]

2. Description of the Related Art FIG. 11 shows an example of a building management system. In this building management system, a center device 1 of a central monitoring system or a self-contained distributed controller 2 controls and outputs information such as names of facilities to be monitored and status names. / O data and graphic data indicating the arrangement of equipment are registered. These I / O data and graphic data require repeated changes even after delivery of the system, due to equipment changes or additions, and the ingress and egress of tenants. In this change work, the supplier of the system discusses the contents with the purchaser, brings back the contents, creates I / O data and graphic data, and writes the created I / O data and graphic data on the data medium. The procedure is carried out by bringing the FD to the installation site and updating and registering I / O data and graphic data. The remote station 5 has a control signal line 3
And a terminal 4 for exchanging control data and monitoring data through the terminal device 4. The terminal device 4 is controlled by the control data from the autonomous distributed controller 2 through the terminal device 4, or the operation state of the equipment device is controlled. The data is sent to the self-contained distributed controller 2 as monitoring data.

[0003]

In such a system as described above, data cannot be registered unless a graphic data registration operator goes to the installation site. In particular, when the system is located in a remote place, costs and days are reduced. Had spent a great deal of effort on the surface. In the event that any failure occurs in the system, there is a problem that quick response is lacking because the recovery work is performed at the installation site regardless of the degree of the failure.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object thereof is to remotely change data, thereby reducing the number of days and costs required for data change. Building management system.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a center device and an independent distributed controller are connected by a LAN, and equipment equipment is exchanged with the independent distributed controller by exchanging data. In a building management system connected to a remote station for monitoring and controlling the remote device, a remote device is connected to the LAN, a service device is connected to the remote device via a public telephone line, and the remote device is registered in the center device or the autonomous distributed controller. When the graphic data or the I / O data is changed, a transfer command is sent from the service device to the center device or the independent distributed controller via the public telephone line, the remote device, and the LAN, and the graphic data or the I / O data is transmitted between the LAN and the remote device. Through the public telephone line Is transferred from the over device or autonomous distributed controller to the service apparatus, modify graphic data, or I / O data transferred in the service device,
While adding, modifying and adding the graphic data or I / O data after the addition, the public telephone line, the remote device and the LA
N to send the updated data to the center device or the autonomous decentralized controller for graphic data or I / O data. The system side transfers graphic data and I / O data to be modified and added to the service device through the public telephone line, and transfers the transferred graphic data and I / O data.
After modifying and adding data with the service device, modify and add graphic data and I / O through public telephone lines.
The data can be sent to the system and registered for update.
Therefore, even if the system is in a remote place, it is not necessary to go to the installation site, and the number of days and cost required for changing data as in the related art can be reduced.
