The communication port unit includes a RAM, a ROM, a GAL, a power supply circuit, an LCD display, and a MAX232 using a high performance processor.

The transmitting / receiving unit exchanges data with the wireless communication device through the RS-232 communication port and sends an SM message instructing the connection from the server computer to the wireless communication device, and the wireless communication device receives the message and transmits it to the main system through the communication port. To pass.

The main system selects the data communication method according to the type of this command and attempts to connect to the Internet network through TCP / IC so that the main system and the server computer can maintain a warm state.

Also, if the wireless communication device is a mobile phone, the standard time provided by the telecommunications company is checked and obtained through the ping command.The main system accepts this time as the system time, and the acquired time if the message should be sent to the server computer at the designated time. An interrupt occurs to transmit data to the server computer through the communication device.

The A / D, D / D, and D / A converters use the A / D conversion function of the microprocessor in case of A / D and the analog value through the sensor using a chip such as ADC0809, which is an A / D conversion chip. In the case of digital conversion and D / A conversion, a chip such as DAC0800, a D / A dedicated conversion chip, is applied to an element requiring analog control.

The data processing unit processes software for recognizing and removing data of noise generated in the performance of the sensor, and uses statistical methods such as regression analysis, multiple regression analysis, and nonlinear regression analysis.

In addition, the noise data may be classified as noise data when the identification process is out of the tolerance range when the average value of the previously acquired data is calculated and compared with the currently acquired data value. Choose how to remove

The power circuit unit, the power selection component unit, and the power failure protection stabilization unit use a method of using a power supply of 220 V and a battery. The contact point of the relay is changed when the power input to the system is cut off through the power circuit. Replaced.

In addition, the battery is connected to the solar panel to supplement the current consumed by the charging circuit, and the main system checks the voltage and current of the battery to prevent discharge and overcharge.

The position and standard time acquisition unit obtains the information by connecting the GPS system with the main system through the RS-232 communication port to obtain the position data and the standard time data, and the main system uses the current position coordinates and the standard time through this information. To a ROM or transfer to a server computer.

In the standard time acquisition part, the reason why the wireless communication device and the GPS system are parallel is because there are two options. Therefore, when the GPS system is not added to the option, the standard time obtained through the wireless communication device is used.

Information is output using the LCD display.

The control system control and status monitoring unit controls and monitors a control object using an input / output port. The input / output port uses an input / output port of a microprocessor and uses an interface chip 8255 for the expansion of the port. It is operated by the main system's instruction or transmits status information to the main system.

The vibration and noise detection unit and the image data acquisition unit acquire noise and image data using a vibration sensor, a voice recognition chip, a CCTV camera, and a digital camera mobile communication system.

3 is a block diagram of a data transmission and reception server computer and a communication unit of the main system of the multi-purpose remote monitoring and management system using the wireless communication device and the Internet protocol of the preferred embodiment, the server computer is connected to the Internet network through a LAN or a modem. The server computer is configured to form an internet network and share data with a computer. The server computer includes a server program driving means, a data processing program driving means, and a GIS.

Therefore, the server program driving means requires a program capable of processing data at all times in order to collect data transmitted from the client in real time, and a tray icon is a small icon that appears at the bottom right of the window when the program driving means is executed. Indicates that this is currently running.

Therefore, in order to process the data transmitted in real time, the program must be running all the time. In order to eliminate the inconvenience of general users using the computer, the tray icon was created.

In addition, the server program driving means is manufactured based on the Internet so that data can be collected in real time. The control of the client dependent on the server is a driving means that cannot be executed in the computer which is not connected to the socket program, that is, the LAN. Since the sockets are connected to each other by searching for an IP address, the socket driving means is mainly used to transmit data to and receive data from different computers in a LAN or a wide area LAN.

When a client connects to the server, the server creates a socket to connect with the new client. That is, the number of clients connected to the socket is made, and the client and the socket are 1: 1 connected, so the server program can control the connected clients by controlling each socket.

All clients must have an IP address, so all connected clients are identified by their IP addresses. The client and the connected Socket are stored in a pointer list. In other words, you can control a specific client or multiple clients using a Socket stored in a list.

Thus, the data passed from each client is received by each socket and designed to be monitored.

The data processing program driving means uses an ADO (ActiveX Data Object) program, and ADO is composed of five object models. Five fraudulent objects consist of five objects such as connection, command, recordset, stream, and record. The Connection object is used to connect to a database, executes a Command Query statement, and a Recordset is an object that contains the result values of the Connection Command object.

The program driving means of the present invention combines with the generated MS data grid control in a state in which the Recordset can be modified to provide a more convenient interface to the user by digitizing it like a general Excel or Access.

In addition, the server program is a program that should always be executed. As its capacity grows, it is unreasonable on the computer, so in order to prevent this, a program that can modify and edit the data is independent. The server simply sends the received data to the ADO Connection object. It only saves the data using, and all editing work is handled by the data access program.

The processing of the data stored in the server program driving means is made in the form of grid, and it is the same type of Excel and Access used by general users, so it can be used for the first time and can be expressed by passing Recordset to MS Data Grid. By using this method, any computer connected to the server computer can manage the data, not the computer on which the data is currently stored.

Using the Recordset created by the Connection, you can graph through the Chart control and use the Chart Control to display various types of graphs such as Excel, compare them by every client, and compare data at specific times, especially all numbers. Graphed.

Database construction using GIS enabled flexible queries and multiple conditions using relational database models. For data accuracy, comparison, and analysis, the basic data structure used raster structure and as an auxiliary structure to solve spatial inaccuracy. It uses vector structure, that is, interlock structure of register and vector.

In addition, the topology structure can be used to analyze the proximity, connectivity, and inclusion relationships to immediately interpret the response to the surrounding area.

The GIS program is designed for the purpose of receiving specific data, and the surrounding situation of the station is also important, and in order to obtain such an important situation, the shape of the station is created in 3D based on the input data when a specific station is clicked.

Digitized maps can be created and tailored to specific situations. A portion of a multiscale map can be selected to be a partial map. In other words, by using a multi-scale map, one area within a map can be represented interactively, and the selected area can be separated into another map.

In order to receive the location and data of a specific object, GPS function is used and GPS and GIS are linked. Based on the data passed by the client to the server, the data in grid form and graph form are output through statistics and analysis. The result is a map and database update.

Finally, an automatic error detection program driving means for analyzing the data passed by the client to the server and detecting the client's error was installed.

Therefore, the main system unit and the server computer described with reference to FIGS. 1 to 3 transmit SMS data to the wireless modem of the main system unit by a wireless modem connected to the server computer, and receive the data through the modem of the main system unit. When control message system is received or a message requesting connection with server computer is received, connection to server computer is established through internet network using TCP / IP as data communication method.

As described above, one server computer and two or more main system units form a communication method so that data can be simultaneously transmitted and received, and using one or more control target systems using a server computer or a mobile phone of an administrator using this communication method. Simultaneously control in real time and configure to transmit / receive data.

This communication method is to send data to the administrator and any mobile phone set in a specific situation according to the setting of the administrator.

As described above, the present invention uses a target monitoring and system control device using a wireless communication device through a high performance microprocessor with excellent system control and computing power, high precision data, stable power supply, and high reliability communication success rate. It can be installed in places where communication and power cables cannot be installed for various monitoring targets such as marine, environment, agriculture, air, buildings, etc., and can receive and monitor data through sensors and video equipment in real time. This makes it possible to share all the information on the Internet through data processing, charting, sorting, and schematization.

In addition, since the multi-control using the Internet network is possible through the DATA communication method of the present invention, it is possible to freely control the mechanical system and the conversion system located in the remote place, so that the wireless factory automation, building automation, environmental monitoring device automation, agricultural / public system When applied to automation, it is possible to guarantee unnecessary wiring, cost reduction, convenience of maintenance, and control excellence.

And by setting the specific situation according to the user's needs, the administrator can receive the message on the mobile phone even when the server computer cannot be monitored, so it is effective to cope with the specific situation regardless of the place and time. It is a very excellent invention.
