The present invention relates to a building management system for detecting the status of a site control point and managing a building situation, and in particular, a building management system having a graphic processing system for displaying the situation data of the site point on a graphic panel. It is about.

In general, management of facilities such as buildings, such as air purifiers, cold and warm heat sources and circulation devices in buildings, water level control devices of various tanks, electric and power monitoring devices, security monitoring devices and fire alarm devices, etc. In the integrated building management system, the situation data is detected by various types of detectors installed on the site in order to grasp the situation of the site away from the central system such as the central control room.

If the status of the site is determined to be abnormal by this data, the data is displayed on the alarm system, which is a separate display device, in addition to the basic system terminal installed in the central control room. It will sound an abnormal condition of the site such as a fire.

Conventionally, in order to see the data detected by the field detector at a glance, a graphic panel was used to provide graphic information in addition to simply displaying numerical values.

However, in the past, since one graphic panel processing means had to be installed in each field detector of each control point to process the detection data on the graphic panel, the field detector and the graphic panel processing means increased as the control point to process the data into the graphic panel increased. The wiring between them became complicated and uneconomical in terms of installation costs.

The integrated building management system equipped with the conventional graphic processing system obtains the data using the sensors installed at the site control points of various forms such as the sensors installed on the site, and then transmits the data to the central control unit that controls the respective sensors. Graphical indicators (graphic panels) which process and also display status were connected to the detector using a distributor. Thus, the data displayed on these graphical indicators could only display status and was connected to multiple indicators using a divider, which made the electrical wiring complicated and uneconomical at system installation.

In addition, since the physical values of the data collected through the sensor were directly displayed through the graphic panel, the loss rate through the display path was large and there was a problem in the accuracy of the information by the loss rate.

Accordingly, an object of the present invention is to provide a building management system having a graphic processing system capable of efficiently processing situation display information using a separate graphic driver controller for displaying information.

Another object of the present invention is the integrated building management system having a graphics processing system that allows the user to easily know the exact state of the information and improve the reliability by using the graphics processing system and to manage the situation of the building in various and efficient ways. To provide.

In order to achieve the above object, the present invention provides a detection means for detecting the situation of the site control point; Direct control means for processing the situation data of the spot control point detected by the detector according to a predetermined program; Central processing means for controlling the overall operation together with the situation management of the building according to the data transmitted and processed by the direct control means; And a graphic processing system for displaying a processing result in the central processing unit, wherein the graphak processing system receives a data from the central processing unit and transfers the data to a lower controller. GDC); A subgraphic driver controller (SGDC) serving as an interface for displaying the data transmitted from the graphic driver controller; And a graphic panel displaying data received from the subgraphic driver controller.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows a schematic diagram of a building integrated management system having a graphic processing system according to the present invention.

In FIG. 1, 10 is a central processing unit that monitors the situation of the entire devices and controls the operation. 20 is a detector for detecting the situation of the site described above. In order to represent the function of detecting the surrounding situation.

30 is a direct controller, which is a distributed control system configured to perform some functions similar to those of the central processing unit, and collects situation data from a plurality of connected sensors 20 and processes data on its own. If the data is to be processed internally, and the data to be processed in the central processing unit (10) that controls the entire function, and transmits the data to the central processing unit (10).

40 is a graphic processing system according to the present invention which receives data from the central processing unit 10 and displays the data detected by the central processing unit 10 according to the characteristics of the data detected from the sensor 20 of the site control point. Play a role.

Referring to the operation of the integrated building management system having a graphic processing system according to the present invention having the above configuration as follows.

A user such as a building checks the situation of a building by checking the situation data detected by the detector 20 by installing the detector 20 at a plurality of site control points to grasp the situation of the building. Normally, the situation of the site is detected as a numerical value, or the change of the situation is detected as state (binary) data indicating the situation of the site.

As such, the data detected through the detector 20 is transmitted to the direct controller 30 which directly controls the detectors 20. The direct controllers 30 receiving the data determine whether the data is data to be processed by a separate operation program from the central processing unit 10, and process the data if it can process itself. In the case of the data in the form required by the device 10, the data is transmitted to the CPU 10 for processing.

The central processing unit 10 always monitors the situation of all site control points through the data transmitted from the direct controllers 30. If a change in the status of the site control point is found from the received data, that is, the sensor 20 detects the state of the site control point installed and transfers the data directly to the controller 30.

The direct controller 30 compares the data with a predefined range by an operation program built in the controller to the central processing unit 10 for comprehensively managing the situation of the building. If the data transmitted from the detector 20 is included in the predetermined stable range, the data is processed by itself without being transmitted to the CPU 10, and the data is not within the stable range. If so, it may be sent to the central processing unit (10).

When the central processing unit 10 receives data from the direct controller 30, the central processing unit 10 recognizes whether the data is data of a predetermined field control point to determine whether the data is to be processed in the graphic processing system and processes the data in the graphic processing system. If the data is not defined to be processed, the data is processed according to its own programmed order of the central processing unit 10.

However, if the data is data prescribed for processing in the graphics processing system, the data is transmitted to be processed by the graphics processing system. In this case, the CPU 10 may be configured as a network control unit (NCU) or a personal computer.

In this case, a method of transmitting data between the devices may be performed using a general communication method such as RS232C, RS485, or TRDRIVER.

The graphic processing system roughly performs the terminal screen and digital display after the sensor 20 of the spot control point detects the situation of the spot control point by an analog or binary value through the processing of the central processing unit 10. Serves to help.

As shown in FIG. 1, a graphic processing system that performs such a function receives a data from a central processing unit such as an NCU or a personal computer and transmits the data to a lower controller. Driver Cotroller (hereinafter referred to as GDC) 50 and a sub graphic driver controller which serves as an interface for transmitting the analog or binary data transmitted from the GDC to be displayed on the display unit. (Hereinafter referred to as SGDC) 60, and a graphic panel serving as a display unit for displaying analog or binary data received from the SGDC 60.

The operation of such a graphic processing system is as follows.

The GDC 50 is generally composed of a semiconductor device having a high integrated circuit, and receives data from the central processing unit 10 and determines whether the data is numerical display data or status display data, and displays the amount. The data is sent to the SGDC 65 for numerical display for both displays in the 60, and to the SGDC 70 for the status display if it is for displaying the status. In this case, the GDC 50 may control the plurality of numerical display SGDCs 65 and the status display SGDCs 70. In this case, the connection relationship between the GDCs 50 and the SGDCs 60 depends on the communication method. It can be changed in various ways.

The SGDC 60 receives the status display and numerical display data transmitted by the GDC 50, and the analog display data is a digital display unit installed in the graphic panel, and the data indicating the status (binary) is transmitted to the lamp installed in the graphic panel. Serving as an interface, one SGDC 60 may control a plurality of digital displays and lamps.

The digital display unit in the graphic panel is configured so that the data received from the numerical display SGDC 65 in the SGDC 60 can be displayed numerically by a decimal display having a certain number of digits displayed on the graphic panel.

In addition, the lamp in the graphic panel receives binary data from the status display SGDC 70 in the SGDC 60 and displays the status or alarm value in the lamp, and the display method used at this time is to display the different colors on each lamp. (E.g. status indicator (red, green), alarm (yellow), etc. can be generated.

The graphic processing system having the component operated as described above always monitors all the control points to be monitored on the graphic panel through the central processing unit, and the sensor in the field, the central processing unit and the graphic processing according to the present invention when the state is changed. By sending to GDC through asynchronous communication between systems and displaying the status value on the graphic panel, monitoring and monitoring status and analog or digital value such as temperature, humidity, and pressure and maintaining and comparing the value with the preset value And digital or analog point monitoring and upper and lower alarm functions that output alarms and display them on the graphic panel. The flow of the data transmitted from the central processing unit 10 is processed on the graphic processing system. It demonstrates with reference.

The central processing unit 10 receives the data from the sensor 20 at the site control point through the direct controller 30 and checks it, and then the data is required to be displayed on the graphic panel in the graphic processing system. To the GDC 50.

Since the number of GDCs 50 included in the graphic processing system is plural, the data transmitted from the central processing unit 10 includes a module ID for selecting a specific GDC 50, actual data processed by the central processing unit, and an SGDC 60. It includes a point address for. The GDC 50 may be selected based on a module ID for selecting a specific GDC. Various methods may be used as the selection method. In the present invention, a polling method is used as an example. That is, if the information indicating the module ID among the data transmitted from the central processing unit 10 is the same as its own module ID (step 100), and if it is different, the corresponding data is moved to the next adjacent module (step 110). Step), repeat step 100. However, if it is the same as its own module ID, the corresponding data is transmitted to the SGDC 60 (step 120).

In addition, when the point ID delivered to the SGDC 60 side is compared with the ID of the SGDC 60 (step 130), if there is a mismatch, the data is moved to the next adjacent SGDC 60 (step 140). If the IDs of the corresponding data match, the transmitted data is accepted. The SGDC 60 recognizes the point address on the graphic panel on which the transmitted data is to be displayed, compares the point address of the digital display unit or the lap with the address (step 150), and if it does not match, the data to the adjacent module. (Step 160) and repeat step 150. However, if the data coincide with each other, the transmitted data is transmitted to the corresponding digital display or lamp to generate a numerical value or an alarm sound corresponding to the value (step 170).

In this way, the conventional display method of displaying data displays the status data by connecting wiring to each of the individual graphic panels, thereby introducing a new type of graphic processing system to solve the complicated wiring problem and the inefficiency of data transmission. In building management, there is an effect that can be configured efficiently and economically with a simple electrical wiring.

In addition, since data is transmitted to the digital amount converted by communication using a sub-controller or the like, there is no data loss and a large amount of information can be processed without loss of precision.
