On a basis of control of the controller 15, proper operations of a boiler and an air conditioner and opening/closing, temperature, and humidity of control dampers of individual ducts, for example, in an air conditioning equipment are controlled, and the power consumption, fuel, water, etc. are held down to a required minimum.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus based on a system that monitors all of the installations of a building and efficiently controls all of the equipment.

In buildings such as nearby buildings, as equipment becomes more sophisticated, l:
! 11 The capacity of the equipment installed there is extremely low, and therefore the energy used here, such as electricity, oil, gas, and water, is also considerable. Therefore, it is important to efficiently manage these facilities in accordance with the building environment from the standpoint of environmental conservation and energy conservation. Option C, in which A.L.G. is managed only by human supervision, requires a large number of personnel and time, and it is difficult to carry out appropriate operation management according to the environment.

The above is a large-scale building, for example, with a floor area of 10.0
In buildings of OOyy12 and above, computers are used to manage the operation of the equipment mentioned above, monitor the status of the equipment, manage its operation, and understand the energy consumption, making management more efficient and saving energy. He is showing his full potential. Measuring and disinfecting building equipment using a computer has the following advantages: That is, (1) optimal bactericidal control can be performed based on the situation of the entire building based on a large amount of measurement data, and predictive planning can be performed using a load calculation program. (2) Complex electric circuits can be replaced with computer programs, making the interior of the 1III board simple and compact. (3
) When changing the operating method, there is no need to completely remodel the control panel; in the case of a computer system, only the program needs to be changed. (4) By using the computer's CR1 display and operation panel19, it is possible to centrally monitor the equipment of the entire building, and it is also possible to easily print out information such as energy consumption status, making it easy to record data. (5)
This makes it easier to control scheduled operation of air conditioners, lighting equipment, etc. by making full use of computer timers.

However, in large-scale buildings, the number of measurement and measurement points for equipment can reach over 1,000 points, and it is necessary to monitor and control the various equipment distributed throughout the building's floors and locations. Concentrating the mechanism and managing it on one computer would make the management structure and equipment too complicated, and it would also make management difficult to manage, reducing the effort of management workers. It will increase. Therefore, in the past, the first
As illustrated in the figure, a system was adopted in which computer functions were distributed, that is, a central monitoring board 1 was installed in an appropriate part of the building, and terminal monitoring boards 2', 2"I2" and 2"
'... is provided. This terminal monitoring board 2', 2" 2

2"'..., l: 9 sensors or breakage equipment are connected to monitor and control the equipment. Therefore, the central monitoring board 1 performs overall monitoring, and each terminal monitoring board 2', 2".

2''... adopts a system in which operation management is performed for each level or unit of equipment.

Although the above method is suitable for large-scale buildings,
In reality, if this method is adopted as is for small and medium-sized buildings, which make up the majority of buildings, the equipment capacity of the monitoring equipment will be excessive and expensive as the number of measurement and imaging points will be reduced. Not only that, but it also complicates its management, and it is not easy to recover the cost required for its introduction with the energy saving effect obtained as a result of the soot and the labor savings for management.

The present invention has been made to solve all of the above-mentioned problems.
