Problems to be Solved by the Invention However, since all of these conventional configurations use dedicated communication equipment, they have electrical levels, modulation/demodulation methods, and transmission procedures unique to the dedicated communication equipment, and other It is difficult to connect to the equipment systems (lighting, security), etc. of the central equipment, and it is difficult to connect the secondary equipment to other equipment systems (lighting, security), etc.
When monitoring and controlling with multiple third central devices, since the system is completely independent, the control information is sent through the first central device, so there is a risk that the information may change, reducing reliability. There was a problem with the lack of.

The present invention solves the above-mentioned problems, and is easy to connect with other equipment systems, and can directly monitor and control the status of a specific terminal controller from a location other than the location where the central device is placed, and transmit control information. The purpose is to provide a building management system that is error-free.

Means for Solving the Problem In order to solve this problem, the present invention includes a plurality of terminal controllers that control a plurality of equipment installed in a building, and a control system for controlling the equipment via the terminal controller. It has at least one central device that centrally monitors and controls the operation, and a network control device, a modem device, and a switch network, each of which is connected to the terminal controller and the central device by a communication line, and a control device that controls each of them. This system includes a facility switching device having an automatic switching connection function, and a private telephone switching device to which the facility switching device is connected via a private telephone line.

Effect: With this configuration, when a call signal with a call number unique to the terminal controller is sent from the central device that monitors and controls equipment via the terminal controller to the equipment switching device that has an automatic switching connection function, The control signal sent to the control device of this device automatically closes the switch network and allows data communication with the equipment via the terminal controller.

Conversely, if a terminal control device connected to the equipment sends out a call signal with a call number unique to the central unit, the equipment will be automatically connected and data communication with the central unit will be performed in the same manner as above.

Communication between terminal devices connected to equipment also has the same effect as above.

When there is equipment connected to a local telephone line and data communication is to be performed with equipment or central equipment connected to a facility switching device, a call signal with an extension number unique to the facility switching device and a terminal controller are used. When a device sends a calling signal with a designated calling number to the local telephone exchange via the private telephone line, the private telephone exchange automatically receives the call to the network controller of the equipment switching equipment with the designated number and transmits the call via the modem. The layer number is sent to the control device, and the control signal automatically closes the switch circuit network, allowing data communication between the two sides. In the opposite case, the terminal controller or central unit connected to the facility equipment first sends a call signal with a specific number and extension number to be sent to the facility exchange equipment, so that the control device can The network receives this signal and sends a control signal to the network control device; the R1 control device issues a signal to connect the private telephone exchange and the equipment for communication. The control device also issues a signal to close the switch network, allowing data communication to continue.

Since it has such an effect, therefore, facility switching equipment is still not used for private telephone exchanges [
It is easy to add or relocate equipment to the line and connect it, and the central equipment can manage each piece of equipment installed within the premises.
