Description

An equipment for monitoring natural environment and the monitoring method}

The present invention relates to a natural environment monitoring device for water quality measurement and examples, alarms used in the environmental field.

Specifically, the present invention can be used in various field measuring instruments such as a depth gauge, a water level, and a scourer without change, and can detect and predict natural disasters such as landslides, collapse of bridges, and overflows of embankments during flooding. The present invention relates to a natural environment monitoring device capable of relaying analysis data and images in real time through the Internet and providing them as necessary if necessary.

In general, in the conventional technology, when measuring water quality in a river or an ocean, a sample is taken and analyzed in a laboratory or a person directly measures a measuring device, which requires a large measurement error and requires a lot of time and personnel. In addition, since it was impossible to measure in real time for 24 hours continuously, it was impossible to forecast and alarm about the risk of deterioration of water quality, and it was difficult to establish a water quality monitoring system at all times such as unauthorized discharge of wastewater at night, and it was expensive.

The purpose of the present invention is to measure the water quality at all times for 24 hours, and when the water quality is abnormal due to the unauthorized discharge of wastewater, the current situation data and video are automatically transmitted to the relevant monitoring personnel by using a regular wired or wireless telephone, and the Internet It also aims to provide technology for relaying water quality measurement, monitoring, forecasting and alarming.

To this end, the present invention connects a water quality sensor, GPS and a digital camera to a personal computer, and automatically analyzes and measures the measured water quality data and the location of the measured data in real time using a program in the computer, and wirelessly installs the analyzed data based thereon. The telephone must be inputted to the telephone or computer of the designated number through the communication telephone so that it can be recognized unattended from a distance.

As it can be used in many necessary places as described above, it is dangerous to call or pager at water quality monitor or related office through general wireless mobile phone attached to computer when water quality measured in the field and their rate of change exceeds set threshold. The software is developed so that users can be notified of the data and access the measurement points at home or office using regular wired or wireless telephones so that they can always know the values in real time and receive their analysis data and video.

The operation and effects of the present invention thus constructed will be described.

First, the present invention installs the sensor S shown in FIG. 5 as a component of the field part 20 at a desired location, and these are connected to the analog-digital converter 5 shown in FIGS. 2 and 1. The computer 7 and 32 are set with the programs to be executed by the flowcharts of Figs. 4A and 4B, respectively. For example, the field unit 20 program may be stored in the ROM 8-1 or may be stored in a separate disk. Therefore, in the present invention, it is assumed that it is stored in the ROM 8-1 for convenience and explanation. In addition, the computer 7 program of the field unit 20 stores reference data of various sensors together. In this state, if the output of the sensor S shown in FIG. ) Is provided to the microcomputer 8 so that the microcomputer 8 recognizes it. In addition, the output of the digital camera 21 is also downloaded by the computer 32 through the serial port, the microcomputer 8 stores the data in the RAM (8-2) by addressing the sensor input data and the image. Then, the reference data stored together with the program is loaded into the ROM 8-1 to compare with each other to check whether there are any abnormalities, and the result is interface 9, input / output unit 4, modem 2, and a wireless mobile communication telephone. 3) to notify. The digital camera 21 captures an image signal and outputs it in the form of a picture file in a digital state, and is provided to the serial port of the computer 7. For this purpose, mutual data between the computer 7 and the digital camera 21 is obtained. It is required to have a built-in program to send and receive, and to provide it periodically, or to provide only when an alarm, which can be set as necessary. Of course, when transmitting the data data including the image data to the central control unit 30, the micro-communication (8) first provides a pre-stored number to be called, and then dials through the modem, when the other party has a dial tone and the reception initial state is completed, Then it sends the result of the sensor value. The outgoing data is transmitted to the central control unit 30 via the wireless mobile communication telephone 3. In the above, the image data is not an essential element, and even if it operates without it, the abnormality of the data can be known. The central control unit 30 receives the data data received through the wireless mobile communication phone 31 and activates the alarm means 35 so that the worker of the central control unit 30 can immediately know. In addition, the computer 32 can receive all the data and store the data, and can easily analyze the data because it can recognize the desired data in real time based on various sensor measurements. Of course, prior to the GPS receiver 35, the position and time of the sensor can be accurately recognized, and there is an advantage of coping with the accurate analysis of the position of the sensor. In addition, since the computer 32 connects to the Internet communication only 33 through the modem 34, it is possible to provide the image and data results to the desired customer in real time.

In addition, when the present invention is described based on the flowchart of FIG. 4A, the computer 7 used in the present invention can turn on the power, run the startup program, and then drive the program of the present invention to turn the GPS receiver 1 on. The current time is displayed (the illustration of the display means of the computer 7 is omitted in FIG. 2) (step 1-1; 110). In addition, by checking whether there are inputs of the various sensors (S) and temporarily stores the input value including the video signal in the RAM (8-2) (step 1-2; 120). The stored sensor value is compared with the reference value (step 1-3); The input value and the comparison result are stored together with the measured time in the RAM 8-2 or in a separate storage means (steps 1-4; 140). The measurement results obtained by the above steps 1-3 and / or steps 1-4 are called and then transmitted (steps 1-5); 150 (steps 1-6). In this case, if the sensor data is transmitted, the measured result can be transmitted in real time (in this case, the receiving receiver and the sending wireless mobile phone are always waiting for transmission), and of course, the transmission time of the received data is 5 minutes or 10 times. It is also possible to set the repetition time by the minute or hour, etc., and transmit it every set time accordingly. If the user sets it to real time as needed, the user only needs to call the cellular phone and keep it in standby mode only when the user sets it to real time.If the time interval is set, it is designated by using the cellular phone every set time. Call the receiver and then send the data. In this case, since a process of storing data for a time interval (time interval) is required, the first to fourth processes 140 may be performed. Of course, you can also send measurement data once a day, week or month if needed. However, the greatest advantage of the present invention is to install the various sensors (S) in the necessary place to receive the sensor output using a multi-channel analog-to-digital converter and to use it in real time using a wireless mobile telephone (3) or a landline telephone It should perform the function to transmit. At this time, the current accurate time and position can be recognized based on the received data of the GPS receiver 1, so that there is an advantage that it is easy to analyze and cope with the data. In addition, since various data are received through the computer 7, various data can be analyzed and displayed on the basis of this, so that customers (viewers) can obtain the effect of providing the reliability and speed of the information.

As such, the data controlled by the field unit 20 is applied to the wireless mobile communication telephone 31 of the central control unit 30 through the wireless mobile communication telephone 3, and the central control computer 32 is the GPS receiver 35. In step 2-1, the clock receives the standard time and synchronizes the clock synchronization with the received data. Then, it is checked whether an alarm signal is input among the received data (step 2-2, 220). If there is an alarm input signal in step 220, the sensor receives and stores data of the sensor and stores the corresponding video signal (step 2-3). Then, the real-time image data and the result data are transmitted to the internet network (step 2-4, 240). If there is no alarm signal input, the signal data is periodically downloaded (step 2-5). Also in this case, the data is periodically updated (steps 2-6, 260).

In fact, the graph of the sensor of the present invention installed in the fire prevention bridge and calculated the depth, width and the like of the ear can be illustrated as shown in Figure 10 has the advantage that can be recognized in real time.
