Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interface unit for controlling and monitoring equipment such as power equipment, lighting equipment, and air conditioning equipment, and an interface unit connected to the interface unit for controlling equipment corresponding to the interface unit. The present invention relates to a central monitoring system including a host control unit that performs monitoring intensively.

[0002]

2. Description of the Related Art Conventionally, a plurality of interface units for controlling and monitoring equipment in a facility field corresponding to power equipment, lighting equipment, air conditioning equipment, and the like, and a plurality of interface units are connected to each other. A central monitoring system from a host control unit that centrally controls and monitors the installed equipment and a setting unit that sets a type code indicating the corresponding equipment field of the interface unit connected to the host control unit in the host control unit. There was something to configure.

[0003]

In the central monitoring system having the above-described structure, since no type code is set for each interface unit, the host control unit determines the field of equipment corresponding to the interface unit connected to the host control unit. It could not be read from the interface unit.

Therefore, the setting unit sets the type code indicating the equipment field corresponding to each interface unit in the host control unit. The host control unit determines the equipment field of each interface unit from the type code set by the setting unit. I knew. However, if an interface unit of a facility field different from the type code set by the setting unit is erroneously connected to the host control unit,
The problem is that the system does not operate properly and the host control unit cannot read the type code from the interface unit actually connected, so it is not clear that the cause of the system abnormality is incorrect connection of the interface unit. was there.

[0005] The present invention has been made in view of the above problems, and an object of the present invention is to easily determine that an interface unit in a facility field different from the type code set by the setting unit has been connected. It is to provide a central monitoring system that can be used.

[0006]

To achieve the above object, according to the first aspect of the present invention, an interface unit for controlling and monitoring equipment in a corresponding equipment field and an interface unit for a desired equipment field are electrically connected. A host controller for centrally controlling and monitoring equipment and devices corresponding to the interface unit, and a setting unit for setting a type code indicating the equipment field of the interface unit connected to the host controller in the host controller And a display unit whose display screen is controlled by the host control unit, sets its own type code in the interface unit, the host control unit reads the type code set in the interface unit from the interface unit, Type code and setting read from the interface unit Results of the comparison between the classification code of the interface unit set by parts, if they are different, being displayed on the display unit that set a different interface unit setting unit are connected. Therefore, the host control unit can read the type code of the interface unit connected to the host control unit from the interface unit, and the type code of the interface unit set by the setting unit,
If the type code read from the interface unit is different, the display unit indicates that an interface unit different from the setting in the setting unit was incorrectly connected. Can be easily recognized as being incorrect.

According to a second aspect of the present invention, in the first aspect of the present invention, the interface unit includes a data storage area for exchanging data with the host control unit and a board type for storing the type code of the interface unit. Dual port memory with storage area set and C
A host control unit connected to the dual port memory via a bus and exchanging data with the interface unit via the dual port memory;
Equipped with PU, CPU of interface unit
Writes its own type code in the board type storage area of the dual port memory, the CPU of the host control unit reads the type code from the board type storage area of the dual port memory of the interface unit via the bus,
The type code read from the interface unit is compared with the type code of the interface unit set by the setting unit. Therefore, the CPU of the host control unit reads the type code of the interface unit through the dual port memory,
The type code of the interface unit connected to the host control unit can be grasped. If the type code of the interface unit set by the setting unit is different from the type code read from the interface unit, an interface different from the setting of the setting unit Since the display unit indicates that the unit was connected incorrectly,
The user can easily recognize from the display on the display unit that the connection of the interface unit is incorrect.

According to a third aspect of the present invention, in the first aspect of the present invention, the interface unit is connected to the host control unit via a transmission line, and the host control unit transmits the type to the interface unit connected via the transmission line. When the interface unit receives the board type request message transmitted from the host control unit, it sends a board type response message including its own type code via the transmission line. The host control unit compares the type code of the board type response message received from the interface unit with the type code of the interface unit set by the setting unit.
Therefore, the host control unit can recognize the type code of the interface unit connected to the host control unit by receiving the board type response message from the interface unit via the transmission line, and recognize the type code of the interface unit set by the setting unit. If the type code and the type code read from the interface unit are different, the display unit indicates that an interface unit that is different from the setting in the setting unit is incorrectly connected. It can be easily grasped from the above that the connection of the interface unit is wrong.
