The present invention relates to a system for comprehensively managing a building by forming an integrated broadband control system using an intranet and the Internet using TCP / IP, and more specifically, a web browser regardless of various types of management control systems. It is possible to manage buildings and control lighting on the Internet using the Internet, so that it is possible to easily manage buildings by accessing the Internet anytime, anywhere, and to control lights in the building through the Internet, and multiple people can access them at the same time. And, it is possible to integrate the management of distributed facilities into one, it is possible to easily remotely integrated management through an Internet browser without additional programs.

The integrated management and automatic control system is implemented to perform energy saving functions by managing / controlling various facilities of the building, and is mainly composed of a central control device, a direct digital controller (DDC), and a control device.

The central control device refers to various devices installed in the central control room where the operator comprehensively controls the building facilities through a system such as a video display device. The central control device includes a host computer, peripheral devices, and all communication devices between a person and a machine. Direct digital control device (ddc) is a digital processing device that is installed in a building and on a facility site to control various facilities with a digital function. It has an independent processing function that collects various facility data and directly controls each device and equipment. And equipment for transmitting the data to another direct digital controller or central control unit. The controller is a device that corresponds to sensors, controllers, valves, etc., and is directly connected to a digital controller (DDC), which is responsible for measuring and controlling the actual data of the facility.

The basic configuration of the system is to configure the DDC communication line under the central control device and connect the DDC for floor equipment control on the DDC communication line so that data can be exchanged through mutual communication between the DDCs to implement air compensation control, interlock control, reservation control, and the like. It is.

However, DDC communication lines having such a series of structures have their own characteristics for each manufacturer of field equipment and for each system that applies the same company's products. The problems are scattered. A representative example is the de-standardization of communication protocols between devices.

It has its own protocol that is reluctant to disclose to each manufacturer that manufactures each device, making it almost impossible to communicate with other companies' products, and even if it is the same company product, it cannot communicate according to its application system. This may cause complexity in the communications environment. This non-standardized communication environment is due to the closed integrated control management environment and brings about a considerable difficulty in configuring the remote management system. On the other hand, the current remote management (TM / TC) configuration does not use a generalized Internet infrastructure network, but uses a leased line (low speed, high speed), which is a method of moving the Internet, and includes costs, real-time management, data stability, Difficulties in transferring large amounts of data. This is because the integrated network between the industrial equipment is not made, the time, cost, facilities, etc. according to the management is duplicated and wasted, there was a problem that must be managed and controlled in a predetermined location, that is, the central control room for the management of the building.

The present invention converts the signals of various sensors in a building into a TCP / IP protocol to configure a network through the Internet network so that the user's computer monitor can indicate the current building status, and the user sends the TCP / IP over the Internet. By converting the protocol control signal to the protocol of the device to control the device, it is possible to integrate other model management systems into one network through the Internet, so that if only the Internet is connected without the need for additional programs through the web browser It aims to provide web-based remote integrated building management control system that enables building management / control and lighting control anytime and anywhere.

The integrated management and automatic control system that enables the integrated management of the building by forming a broadband integrated control system using an intranet using the present invention TCP / IP to achieve this technical problem, the serial communication protocol of the controllers in the building To convert the TCP / IP protocol into the TCP / IP protocol and bypass the TCP / IP protocol input and output signals to the respective input and output ports. In order to control, the protocol conversion device can be directly connected to the sensor in the field, and the signal input and output from the end can be communicated with the manager, and it can be converted into TCP / IP protocol by receiving input signals from other PLC devices. It consists of the upper end.

As shown in FIG. 1, the distal end includes an analog signal receiver 130 for receiving various analog data such as temperature and humidity in a building, and a digital signal receiver for receiving various digital data such as a security sensor; 110), an analog signal transmitting unit (Analog Output; 140) to pass the data received from the upper end back to the analog sensor, and a digital signal transmitting unit (Digital Output; 120) to pass to the digital sensor, the analog signal and the digital signal Consists of a coupling part coupled to the upper end to transmit and receive the signal of the upper end.

The upper part is a coupling part for coupling to send and receive signals with the terminal as shown in Figure 3, RS-232C serial communication ports 320, 330 and RS that can communicate with other devices using the serial communication port -422,485 serial communication port 340, Ethernet port 350 for connecting to the Internet, built-in CDMA wireless modem 360 for message service and emergency remote backup configuration, and USB 310 to enable Bluetooth communication 32-bit CPU 370 that controls the overall functions of the port and protocol converter, and a flash memory 380 on which application programs are mounted.

Analog and digital I / O signals can be received through the end of the protocol converter so that the received signals can be processed at the upper end to provide information to the user using the Internet communication line.

In addition, a device using a protocol other than the TCP / IP protocol is connected to the serial communication port for each protocol in the upper part and bypassed to the TCP / IP signal by the protocol converter.

A device that has a feature for controlling each building with a protocol for control is called a MCU (Main Control Unit). The MCU can monitor and control the status of various sensors.

Referring to the flowchart of the data shown in FIG. 2, the process of transmitting the data 210 collected by the digital signal receiver 110 or the analog signal receiver 130 to the gate server 220 and receiving the control signal from the gate server DO 120 Or AO 140, and if there is no control signal or if the control signal is transmitted to the data collection step 210 again.

On the other hand, as described above, the software configuration that enables communication between the manager and various control devices and sensors of the building is mounted in the flash memory, and determines the protocol of the input signal according to the program, By passing, communication between each other is possible, and the match between different protocols and TCP / IP protocols can be freely changed and added by adding and modifying programs.

This MCU and gate server configuration enables not only analog data, digital data collection, monitoring, and control but also communication with other devices using serial communication, Bluetooth, and TCP / IP communication. Gathering enables the integrated management by converting protocols between different models into a single protocol.

FIG. 4 converts a signal input when different devices 410, 420, 430, and 440 communicate with each other through a connection to a single communication port through a gate server 450, and transmits the signal in a reverse direction. The flowchart reversely shows that the devices are managed by integrating different devices in the manager PC 460 by being delivered to the respective devices.

In addition, the transmission and reception of the gate server is performed using TCP / IP as a standard, but the transmission and reception of the serial port is also possible, so that the PC can be monitored using various communication ports.

The protocol conversion process according to the characteristics of the gate server according to the above is specified in FIG. When another type of device receives data (510) and sends it as a communication signal (520), the gate server receives the TCP / IP protocol corresponding to the protocol and converts it (530) and then outputs (540). Protocol conversion is done through

Looking at the process of the data is converted and delivered to the administrator PC as follows. First, data about various information of a building is collected from an analog signal receiving unit AI and a digital signal receiving unit DI and inputted to an end portion, and the input data is transmitted to an upper end portion.

The data is transmitted using the protocol of the PLC, the protocol is based on TCP / IP, the control code to control the PLC, PLC status information, device status information, device control information, code information, system reservation This includes code. The protocol can be divided into three areas: a data head, a body, and a flag. The data head includes information necessary for communication, information necessary for transmitting PLC information, and information on data to be contained in the body. And the body describes the detailed information according to the data head. The flag determines the basic unit of reading or writing when reading or writing data recorded in the body part. In the data head portion, a source, a target, a type, a size, and a command reserved area exist. The source and the target store information of a sender transmitting data and information of a receiver receiving data. Type refers to the data type of the current frame. This part is used to distinguish between the type of the source and the target.

The data transmitted to the upper part is read by the protocol conversion gate server program loaded in the flash memory, and then converts the data head, body and flag information into the data head, body and flag of the standardized protocol. It is sent to the gate server on the user's PC through the internet.

Data sent using the standardized protocol is interpreted by the user gate server, and the standardized protocol is interpreted and monitored by the user. When the control command is sent from the user's PC to the PLC, the transmission is performed in the same manner as in FIG. 13B.

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

First of all, the sensor is connected to the sensor and the digital input device at the end of the protocol converter of the gate server. When connected as described above, if the indoor light is on, the digital signal of 1 is sent, and if the light is off, the digital signal of 0 is sent to indicate the on / off state of the lighting. The device converts the signal into a TCP / IP signal and inputs it to the gate server. The TCP / IP signal input to the gate server is transmitted to the user's computer through the Internet and displayed on the monitor.

On the other hand, the control unit for controlling the on / off of the light by the sensor is connected to the upper end of the protocol conversion device, when the user's command is issued through the Internet, the protocol conversion device converts the TCP / IP signal into the control signal of the light By converting and sending a control signal through the upper end it is possible to turn on / off the light.

Therefore, the user can determine the on / off of the lighting of the entire building or the limited room through a computer monitor connected to the Internet, and control the lighting of the building through the Internet according to the identified signal.

Therefore, if you can access the Internet not only inside the building but also outside the building, it is possible to determine whether the lighting inside the building is on or off, and send a control signal to control Bildi's lighting outside the building according to the data. It can be.

On the other hand, the use of the protocol conversion device is not limited to the lighting device of the building, but can be applied to all the control and management devices that control the PLC program inside the building, a system for managing a building using the protocol conversion device as described above Looking at it as follows.

First, a gate server capable of storing and managing information of a system for managing a building is provided, and the gate server and a protocol converter are connected using an Ethernet port.

And it connects various sensors and controllers to manage the building, and connects them to the standard port on the upper part of the protocol converter according to various serial communication protocols used by those devices.

For example, if the port of the device that controls and manages the elevator uses the RS-232 port, and the air conditioner that controls and manages the temperature uses the RS-422 port, RS- at the top of the protocol converter in the gate server. It is connected to 232 and RS-422 port, respectively, so that it can input / output signal.

In order to convert the protocol of the connected devices to TCP / IP, which is the Internet protocol, the conversion is performed at the upper end of the protocol conversion device.

In the protocol conversion operation, a signal input from the upper end is first stored in a flash memory, and the stored signal is interpreted by a CPU installed at the upper end. After the CPU interprets the signal, it finds the TCP / IP protocol that matches the signal in the database by the program entered into the flash memory, and finds the TCP / IP protocol that matches the input signal and sends the information to the user through Ethernet. Will be done.

On the contrary, when a user sends a command signal, the CPU receives a command signal of the TCP / IP protocol through the Internet and interprets the signal to send a signal to a device that seeks and controls a protocol signal matching the signal from a database. will be.

On the other hand, the signal coming from the various sensors of the building can be directly communicated by the analog signal transceiver and the digital signal transceiver at the end of the protocol converter.

All signals transmitted from the building are stored in the gate server, and the information in the storage server is transmitted through the Internet so that the user can always identify the state and information of the building anytime, anywhere, and identify problems and prompt response thereto. It will let you do it.

Figure 6 is an exemplary application of the present invention to a building management system, each gate server is assigned a public IP by installing a bypass device on the sensor and control device side and the administrator side 610 for sensing information of the state of the building. Due to this, the system configuration diagram converted to a multiple access environment through the Internet is shown.

The serial communication protocol is converted into TCP / IP communication protocol through a series of processes as shown in FIG. 2 and FIG. 5 to enable the construction of a building management system irrespective of region or distance, and also between gate servers. The use of TCP / IP communication protocols does not limit the use of TCP / IP applications. In other words, not only the web browser installed on the manager PC but also a function that enables the existing management system, that is, the management HMI program configured to be used only in the management area, can be used after being installed on the remote manager PC. .

When connected to the serial port (611, 711a) instead of the Ethernet port of the gate server (610, 710a) installed on the manager side, serial from the existing management HMI program installed in the remote manager PC (640) or measuring device (740a) The communication command 710b is converted (720b) from the gate server to the TCP / IP, and then transmitted (730b) to the gate server on the industrial equipment side and received (740b), the gate server on the control device side is converted to TCP / IP. It restores the serial communication command (750b) and transmits it to the controller in the building (760b), so that the serial communication command from one remote location is transmitted to another remote device without being limited to the distance. And the result can be confirmed in the remote gate server (630, 730a) through the data collection again. This makes it possible to use existing management programs that are familiar to administrators, and allows administrators to adapt to the migration of management systems so that they can adapt to Internet-based management systems without difficulty.

FIG. 9 illustrates a system configuration of building remote integrated management according to the present invention in a structure capable of not only one-to-one remote communication but also many-to-one remote communication as shown in FIG. In more detail, it is a configuration of a system that enables multiple access by integrating each management system of a distributed building of several regions or building management systems of a one-to-one integrated region as shown in FIG. 6. In addition, the gate server is installed on the control unit side (920, 930, 940) and responsible manager side (910) in the building distributed in each region to enable the administrator's PC to be connected via the Internet through the public IP. It enables integrated monitoring and control through the internet, and local managers can also access and control gate servers in each region via the Internet.

The reason for this distributed multi-access configuration is for more efficient management as the scale is more comprehensive as described above, so that it can be extended to national scale or international scale as security policy allows. It also has a feature that allows the use of unauthorized IP to configure a multi-access remote integrated management system for areas where public IP cannot be used for security reasons, system configuration reasons, or regional reasons.

FIG. 8 illustrates the connection between an unauthorized IP network and a public IP. A gate server is installed on top of management systems constructed in each isolated and closed environment. All measurement devices 860, sensors 870, etc. connected to the bottom of the server can be configured to remotely manage the local administrator's PC (880). When the remote integrated management request to the public IP is configured in the private IP integrated management system configured as described above, the configuration of the gate server 810 using the public IP is installed and the gate servers 820, 830, and 840 of the private IP network band are configured. If the target point is set to the gate server 810 using the public IP, it is possible to communicate with the gate server of the non-certified IP network band that finds the target point, so that it can monitor and control the devices of the non-official IP band. .

In summary, we have gate servers 920, 930 and 940 in the building to collect from the data end of each controller, send the data to the upper end to convert it into a single protocol and use an Ethernet port to integrate the integrated gate server (910). Send data to The transmitted data is mapped in the integrated gate server so that data from multiple regions can be managed in one place. If the integrated gate server 910 uses a public IP on the Internet, the area managed by the gate servers 920, 930, and 940 in each region can communicate using an unauthorized IP and can use a public IP. Do. Administrators in each region can also access the corresponding gate servers 920, 930, and 940 via the Internet to monitor and control the status.

In addition, the integrated manager is connected to the integrated gate server 910 can simultaneously monitor and control the area that each of the lower gate server (920, 930, 940) manages, as shown in Figure 10 connected to the gate server ( I) After collecting the model data 1010 and converting it into a single protocol (1020) and transmitting it to the integrated server (1030), the administrator determines whether a request for data (1040) may provide the data to the administrator (1050). Return to the data collection step 1010.

FIG. 11 is a flowchart illustrating a data flow of an integrated gate server. The data collected in each region is collected 1110, and the collected data is managed 1120 and then provided to the manager according to whether or not the manager requests data 1130. You can also collect data (1110) to monitor again.

FIG. 12 shows the flow when the administrator requests the data collected and processed by the gate servers as shown in FIG. 10 or FIG. 11. When the administrator makes a connection 1210 via the Internet via a web browser, the authentication process ( 1220, and after the authorization is requested to request data to the local gate server or integrated gate server (1230), receiving the data according to the result of the request (1240) and the control signal using the web browser screen configuration (1250) In this case, the control signal is transmitted (1260). When the control signal is transmitted, the control result data is transmitted again (1270), and when the control signal is not transmitted, the control signal is returned to the data receiving step (1240). do. Therefore, the administrator can access the gate server (integrated gate server or local gate server) by using a web browser or an Internet access application, and the gate server provides a web page format screen and data. It provides data to the user using HMI program to monitor and control. All of these communications are done using the Internet standard protocols TCP / IP and UDP / IP. The gate server has an embedded web server so that administrators can monitor it anywhere at any time that provides an Internet connection environment. Due to the nature of the web, multiple administrators can manage it in different places at the same time. In addition, the gate server has a built-in CDMA modem, which can send SMS messages to the administrator through a wireless connection using a CDMA network even when the Internet communication line is disconnected, and transmits the status of various measuring devices in the field without disconnection. And built-in Watchdog function can effectively cope with instability in the system itself by initializing through automatic reboot in case of abnormality.

The present invention is an integrated management system of a building capable of multiple access through the Internet using a gate server. If the Internet is connected, a management system irrespective of distance and place is established, data collection, high speed data communication, and monitoring through a web browser. And control management. Therefore, the lighting can be controlled through the Internet to turn the lights on and off, so that the lights can be turned on and off without moving to the switch to turn on the lights, and the status of the lights can be checked at places other than inside the building. It can be controlled immediately, which has the advantage of saving energy.

In addition, the gate server according to the present invention can be connected to a variety of terminals (PC, PDA, mobile phone, etc.), and after the connection of monitors of the measuring devices connected to the local gate server or a single gate server through a web browser without additional software installation and It can be controlled and connected with the upper system (ERP, etc.) to provide real-time management function regardless of time and place, and to upgrade equipment function remotely and prompt real-time response in case of trouble, cost reduction by minimizing travel, minimum number of people System integration for management, building a remote integrated management system of the building through the Internet connection is possible.
