Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring control system using a portable communication terminal for building management.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram of a conventional supervisory control system for building management. The monitoring personal computer is connected to a distributed processing device for air conditioning, a distributed processing device for electricity, and a PBX connection device via a network.
It is connected to the S base station and can communicate with a business-use PHS terminal for emergency calling.

However, the conventional monitoring and control system is composed of a monitoring device unique to each equipment manufacturer and a unique automatic control network, and the control computer and interface are different for each manufacturer. Therefore, in order to monitor and control each facility in a unified manner, software and hardware are required to absorb the differences between the manufacturers, which complicates the system and increases the cost. In addition, when a business PBX is connected to this system, there is a problem that a PBX connection device of the interface unit and connection software are further required.

In recent years, LONWORK has been developed as an open monitoring and automatic control system independent of a specific manufacturer.
S (registered trademark), general-purpose sequencers, and the like are receiving attention. However, digitalization of these automatic control devices is advanced, and it is assumed that monitoring is performed by a monitoring computer.Therefore, the devices themselves do not have indicators, etc. It is often difficult to do. Therefore, a monitoring method using a mobile communication terminal has been proposed.

FIG. 4 is a configuration diagram of a monitoring control system using a portable communication terminal. This is a laptop computer or PDA equipped with a WWW browser or dedicated application.
(Personal Digital Assistant), etc., and a wireless LAN or PHS for business use to access a monitoring and control network (intranet). Using a mobile phone having an Internet access function such as i-mode (registered trademark), This is a method of accessing the monitoring and control network through a dedicated line.

[0006]

However, when a notebook personal computer is combined with a wireless LAN or a business PHS, the size, weight, and ruggedness of the main body of the personal computer, and the short duration of the battery are reduced. There is a problem if the facility manager who patrols the inside always carries it. In particular, when PHS for business use is used, PB for PHS for business use
More cost is required to connect X, and further, such as an access server and a PBX connection device, and depending on the model, connection may not be possible.

[0007] In addition, a mobile phone having an Internet access function such as an i-mode has a problem that communication cost is high and reliability is low because the mobile phone passes through a packet network center of the mobile phone or the Internet. . Although it is possible to communicate without going through the Internet by connecting the packet network and the in-building LAN with a dedicated line in order to increase the reliability, a dedicated line is separately required, which further increases the communication cost.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a building management supervisory control system capable of reducing equipment costs and communication costs.

[0009]

In order to achieve the above object, a building management monitoring and control system according to the present invention connects an automatic control device for a building to a network via a gateway, and connects a monitoring computer to the network. , An automatic control device after each of the gateways and an automatic control network unit for connecting them, a mobile communication network including a mobile terminal proxy server, a LAN connection base station, and a mobile terminal device. The portable terminal device transmits and receives character information to and from the portable terminal proxy server, the portable terminal proxy server communicates with a monitoring computer or gateway on behalf of the portable terminal, By converting the communication of monitoring and control and the communication of the mobile terminal, monitoring and control can be performed by the mobile terminal alone. And performing.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of a building management monitoring and control system according to the present invention. FIG. 1 is a system configuration diagram, and FIG. 2 is a diagram for explaining a processing flow.

In FIG. 1, a monitoring network section (a) comprising a heat source gateway, an air conditioning gateway, an electric gateway, a monitoring computer, a printer, and a network connecting them, an automatic control device after each gateway, and It comprises an automatic control network unit (b) to be connected, a mobile communication network unit (c) including a mobile communication terminal data conversion server, a LAN-connected mobile communication device base station, and a mobile terminal device.

Control systems such as heat source equipment, disaster prevention equipment, sanitation equipment, lighting equipment, air conditioners, and fan coil units are connected to the heat source gateway, the air conditioning gateway, and the electric gateway. Further, the configurations of the monitoring network unit (a) and the automatic control network unit (b) differ depending on the building scale and building use. In addition, a configuration in which control systems for air conditioning and electric equipment are mixed in one gateway is also conceivable.

Each of the gateways and the monitoring computer operates a monitoring control program internally, and data of each node can be exchanged between the gateway and the monitoring computer by inter-process communication. Normally, monitoring and control can be performed directly by the monitoring computer, but remote monitoring or control can also be performed from a remote monitoring personal computer connected to the network by accessing the monitoring computer. .

In this system, a LAN-connected base station is used to connect a portable terminal to a network. Thus, the portable terminal can be used without using the PBX. However, a portable terminal alone cannot connect to a network and directly communicate with a monitoring computer or a gateway. Therefore, as shown in FIG. 1C and FIG. 2, a proxy server for portable terminals is installed. The portable terminal transmits / receives character information to / from the portable terminal proxy server using the short message between portable terminals. The server communicates with the monitoring computer and the gateway in the same manner as the remote monitoring personal computer on behalf of the mobile terminal, and acquires monitoring data and gives control commands. The server performs the conversion between the monitoring control communication and the mobile terminal communication, so that the mobile terminal can perform monitoring and control alone.

[0015]

As is apparent from the above description, according to the present invention, by combining a facility monitoring / automatic control system in a building with a portable communication device, it is possible to grasp the operation status of the facility equipment, perform remote operation, Allows administrators to make emergency calls. In this case, a PBX, a PBX connection device, and the like are not required, so that equipment costs can be reduced, and communication costs such as a public line cost and a dedicated line cost can be reduced. In addition, the facility management can be performed as it is with the business-use PHS used in daily work, and it is not necessary to carry equipment separately.
