Description

Technical Field

[0001] The present invention belongs to the forefront of water environment monitoring technology and focuses on providing an innovative intelligent multi-parameter water quality observation / monitoring terminal device. Background Art

[0002] In modern society, the water ecological environment, including rivers, lakes, oceans and farms, plays an indispensable role. With the enhancement of environmental awareness, the development of marine monitoring technology and the progress of aquaculture, the demand for water quality monitoring is growing. The accuracy of water quality monitoring data is directly related to the effectiveness of scientific research results and the accuracy of scientific decision-making, and is crucial for scientific decision-making in environmental protection and water resources management. In the wave of scientific and technological progress, it has become particularly urgent to apply advanced technology for scientific, economical and efficient water quality monitoring. It is not only the driving force for industrial upgrading, but also an inevitable trend of social development.

[0003] The rise of the Internet of Things (IoT) has given new vitality to water quality monitoring. By deploying smart sensors at monitoring points, it is possible to identify chemical and physical parameters in water, such as pH, dissolved oxygen, and concentration of harmful substances, and track water quality trends in real time. Especially in sudden water quality problems, such as water pollution incidents caused by industrial leaks or natural disasters, the application of IoT technology demonstrates its vital role. By establishing multiple monitoring nodes, a comprehensive water quality monitoring network is constructed to achieve seamless monitoring of vast waters and ensure coverage of all potential risk points. Relying on the IoT platform, data is automatically collected and analyzed, greatly reducing the reliance on manual operations. Through big data analysis, potential water quality problems can be predicted and identified, providing empirical data support for decision makers. In short, the application of IoT technology has made immeasurable contributions to the effective and continuous monitoring and efficient management of water quality, as well as environmental protection and the rational use of water resources.

[0004] The current water quality monitoring technologies on the market are mainly divided into two categories: box-type and portable. Box-type equipment is known for its high precision and multi-parameter monitoring capabilities, but it is bulky and has high requirements for power stability, which limits its application in outdoor and remote areas. Although portable devices are convenient for on-site monitoring, they have limited battery life and insufficient measurement accuracy. They can usually only measure one or two parameters, which is insufficient in complex water body analysis and long-term continuous monitoring. In terms of data processing and storage, whether it is box-type or portable equipment, most rely on memory cards. This data storage method is not conducive to real-time analysis and limits the effective use of data. In terms of equipment control and maintenance, many existing devices rely on manual on-site operations, which increases costs and reduces efficiency. Although wireless data transmission technologies such as Bluetooth and Wi-Fi have become increasingly popular in water quality monitoring equipment in recent years, their processing capabilities are still limited and most of them are only effective in signal coverage areas.

[0005] In response to these practical needs and challenges, the present invention proposes a multi-purpose water quality monitoring terminal device. The device aims to break through the limitations of traditional equipment such as reliance on cables, difficulty in long-distance transmission, bulky size, and high cost. It integrates the advantages of wireless data transmission, remote control, multi-parameter acquisition, portability, flexibility, and high-precision monitoring, and provides an integrated, efficient, and scientific solution for the acquisition, data transmission, and management of water quality parameters. The vision of this device is to become a monitoring tool that is easy to operate and can generate high-quality data. Its design concept aims to combine the accuracy, portability, and ease of use of multi-parameter detection, and to be able to operate stably in various complex environments, while providing efficient data transmission and processing capabilities to ensure data accuracy and promote rapid decision-making. Against the backdrop of emerging technological innovations and diversified monitoring needs, this invention is of milestone significance for the future development of water quality monitoring technology. Summary of the invention

[0006] In order to achieve the above objectives, the present invention introduces an intelligent multi-parameter water quality observation / monitoring terminal. The design of this terminal adheres to the concept of flexibility and intelligence, and is suitable for a variety of application scenarios, including ship-mounted, surface buoy-fixed, shore-fixed, and handheld and portable modes. Once deployed, the terminal equipment can automatically collect water quality data and automatically transmit it through a preset wireless network without human intervention, which significantly improves the efficiency of monitoring work. The monitoring terminal has configuration options for a variety of communication modules, including 4G / 5G, LoRa, NB-IoT, etc., and can automatically or manually select the most appropriate transmission method according to the actual environment to ensure instant data upload and low-latency feedback. In addition, the terminal has been carefully designed to work continuously for a long time in an outdoor environment, has excellent weather resistance and excellent battery life, and can operate stably under various climatic conditions. The present invention realizes the integration of measurement, control and transmission, greatly simplifies the operation process, and improves work efficiency. Water quality monitoring personnel do not need to go to multiple monitoring points to collect data in person, but can obtain data in real time remotely, thereby achieving rapid response and scientific decision-making. The high-precision sensors and advanced intelligent data algorithms built into the device jointly ensure the accuracy and reliability of the collected water quality data, providing solid data support for scientific research and environmental monitoring. In general, the intelligent multi-parameter portable water quality monitoring terminal of the present invention not only revolutionizes the method, efficiency and accuracy of water quality data collection, but also realizes low-cost and high-efficiency water quality monitoring through innovative integrated technology. This innovative achievement will bring about a breakthrough in water environment protection work, and will have a profound and positive impact on maintaining public safety, promoting scientific research and protecting natural resources.

[0093] The following takes the LoRa+4G communication version as an example to illustrate the general operation process:

[0094] After pressing the power button 23, the device starts to start, and the third relay 162, the fourth relay 163, and the fifth relay 164 will start to control the power on and off of the first water quality sensor interface 1625, the second water quality sensor interface 1626, and the third water quality sensor 1627 in turn to automatically detect the sensor type word. After completing the self-test, the single-chip microcomputer 1628 starts to coordinate the work of each sensor. The temperature and humidity sensor 1613 collects the temperature and humidity values ​​of the device, the air pressure sensor 1617 obtains the current atmospheric pressure value, the power sensor 1611 obtains the voltage value of the lithium battery pack 15, and the GPS sensor 172 obtains the latitude and longitude and time of the current location of the device. These sensor data will eventually be transmitted to the single-chip microcomputer 1628 for processing. When the user issues a sensor working command through the host computer, the sensor of the corresponding channel will start to collect data and enter the single-chip microcomputer 1628 after converting it to TTL1616 through RS485; during the collection process, the single-chip microcomputer 1628 will automatically control the start and close of the sensor according to the collection frequency and time, so as to achieve the purpose of reducing power consumption. The first water quality sensor interface indicator light 1625, the second water quality sensor interface indicator light 1626, and the third water quality sensor interface indicator light 1627 are used to intuitively see which interface is in working state. The device uses the LoRa communication mode by default, and only changes to the 4G communication mode when the user manually presses the communication mode switching button switch 24. When in the LoRa communication mode, the signal is sent to another LoRa antenna 72 on the gateway through the LoRa antenna 20. The gateway needs to be placed in a place with a Wi-Fi signal and enter the Wi-Fi name and password through the Bluetooth module 745. Then the Bluetooth module 745 transmits the data to the single-chip microcomputer 740 for processing and feedback and sends it to the Wi-Fi module 741 for networking. In addition to sending the collected data to the upper computer through wireless transmission, it will also be sent to the inserted TF card in the second block layer TF serial port connector 171 through the TF storage card module interface 168 for local storage. The OLED screen 22 will display some device information (including: time, date, instruction, power, water quality sensor interface channel usage, temperature, humidity, sampling frequency). When the OLED screen button switch 25 is pressed, the screen will turn on. The first status indicator light 1622 is green and lights up when the program is running normally. The second status indicator light 1623 is yellow and lights up when the device is in standby mode. The third status indicator light 1624 is red and lights up when the device is abnormal. When the host computer sends a signal to open the channel or needs to locate by sound, the alarm 26 will emit light and sound. The solar interface 13 and the 12V DC input interface 14 on the device casing are used to connect external solar panels and power cords to improve battery life when the device needs to undertake long-term monitoring, and are respectively connected to the solar interface 1705 and the 12V DC input interface 1708 on the power board.All input power will first be processed by the power board 170 (solar to 12V DC module 1700 and 12V DC to 5V DC module 1704) to 5V and 12V power supply voltages, and then input current to the 5V power input interface 169 and 12V power input interface 1610 through the 5V output interface 1707 and 12V power output interface 1706 respectively. The battery charging end DC female socket plug 1701 and the battery discharging end DC female socket plug 1702 on the power board are connected to the lithium battery pack 15, responsible for the charging and discharging of the battery. The power board switch interface 1703 is connected to the power button 23.
