Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to the operating status of equipment such as buildings and factories, electricity,
Manage consumption of gas, water, etc., and each i1Q! ! Concerning a centralized monitoring system that controls equipment.

[Prior art] Control of electricity, gas, water, etc. in buildings, factories, etc., C visibility of fire alarms, security alarms, etc., lighting equipment, sky *5
A system is known in which a computer is used to centrally control Ar, a refrigeration system, a water supply system, a boiler, and the like.

In such a system, a manual panel is installed between the computer and the equipment installed in the building or factory in order to provide backup in case something goes wrong with the computer. The switch on the manual panel was set to ``manual,'' and backup control of the equipment was performed manually.

Normally, the selector switch on this manual panel is set to ``auto'', and the signals from the equipment are directly input into the combination, and the signals from the computer are input to the equipment.
control signal is output. Set the selector switch on this e-board to "f"
When the switch is switched to "first", the presence or absence of a signal from the equipment equipped with g2 is displayed with a lamp, and an 0N-OFF signal is sent to the equipment by the operator operating the "output signal dummy switch" installed on the manual panel. Output. In other words, from the display status of the lamp installed on this manual panel, for example, it can be determined whether the air conditioner should be turned on or off based on the 0N-OFF signal of the thermostat. You can remotely control the air conditioner by operating ``. Therefore, this
The J board also served as an adjustment device to check the presence or absence of signal transmission between the equipment 81 ri at each site and the computer when the system was introduced.

However, this f: moving plate differs depending on the specifications of the equipment in each building and factory, so it has to be manufactured as a product, so it is expensive and requires a considerable amount of El to manufacture. There is a problem in that the panel cannot be designed until the system specifications are determined in detail, and it also takes a considerable amount of time and effort to change the specifications. Furthermore, manual panels have a complex structure with a large number of switches and lamps housed in tall cubicles for operating and confirming a large number of controls, making them difficult for amateurs to operate. , it had to be operated by a dedicated operator.

In addition, computers used to manage and control such buildings and factories must input pulse signals from a large number of equipment and send control signals to each equipment based on the input signals. A medium-sized computer with a fast response speed and the ability to process large amounts of data is needed. However, such medium-sized computers have the drawback of being expensive. As described above, since manual panels and computers are expensive, it is necessary to invest a large amount of money in installing the system.

Therefore, the purpose of the present invention is to reduce the cost of the system, shorten the production period, facilitate and speed up specification changes, and further facilitate operation in the above-mentioned centralized monitoring system for buildings, factories, etc. There is a particular thing.

Means for Solving Problem C 1 In order to solve the above problem, in the system of the present invention, the management and i, II control of each equipment R in buildings, factories, etc. The data collected by the computer and the u-controlled microcombi 1,
Humidity, energy consumption, operating status of each equipment, etc.
- Data processing such as displaying data and analyzing and editing the data is performed by a versatile terminal device, such as a computer, a personal computer, a word processor, and a multifunctional terminal with multiple functions.
This terminal device performs the role that was previously performed by a conventional manual panel.

That is, the centralized monitoring system of the present invention connects each equipment to a control microcomputer or a terminal device in a switchable manner using a changeover switch, and also enables signals to be sent and received between the control microcomputer and the terminal device via a communication line. Normally, the selector switch is switched to the control microcomputer 1-1, the control microcomputer manages and controls each equipment, and the terminal device controls the control based on the input signal from the control microcomputer 1-1. Displays the operating status of each piece of equipment and performs data processing, and during normal operation, the changeover switch is switched to the terminal device, and the signals from each piece of equipment are displayed on the terminal device. So each stage is 11? It is possible to send control number 13 to + equipment.

In one embodiment of the present invention, the control microcomputer and each equipment are connected via an IP? It continues.

[Function] In the system of the present invention, data collection from each piece of equipment and A and II control of the equipment are normally performed by a control microcomputer, and data display and data processing are performed by a terminal device such as a personal computer. Since the functions are uniform, the control microcomputer can collect a large amount of data, and the terminal device only needs to be operated when it is necessary to display or process data, and can be used at other times. Can be used as Nigi OA equipment. Furthermore, since the data processing is carried out on a versatile terminal, the content of the data processing can be easily changed as desired by changing the block diagram at the user's J3.

If an abnormality occurs in this control microcomputer, when the changeover switch is switched to the terminal device, signals from each equipment are displayed on the terminal device, and based on that, the work plan is changed to the keyboard of that terminal device, etc. By manually sending control signals to each equipment device using the traditional hand! It can play the role of lla&.

When the control microcomputer and each equipment are connected via a transmission device that performs serial-to-parallel conversion of signals,
Since signals are exchanged between multiple installed M devices and the control microcomputer using serial signals, there is no need to add signal lines when adding monitoring and control controls, making it easy to change the system. It is.
