Description

Technical Field

[0001] The invention relates to a multifunctional river water quality monitoring buoy, belonging to the technical field of water quality monitoring buoys. Background Art

[0002] Water quality testing is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality conditions. The testing scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various types of industrial drainage.

[0003] For example, the application No. 201510209783.9 discloses a water quality vertical profile monitoring system, which includes a buoy main structure, a vertical lifting mechanism, a power supply unit and a water quality monitoring instrument; the buoy main structure includes a buoy body, a sealed cabin cover and a buoy body bottom pipe; the sealed cabin cover is covered on the buoy body, the buoy body bottom pipe is arranged at the lower part of the buoy body, the buoy body is provided with a hollow pipe, and the hollow pipe extends to the buoy body bottom pipe;

[0004] The power supply unit and the water quality monitoring instrument are arranged in the buoy body, the vertical lifting mechanism is arranged on the closed cabin cover, and the closed cabin cover is provided with an opening, the cable of the vertical lifting mechanism passes through the opening and is connected with the probe of the water quality monitoring instrument, and a tail pipe is provided under the bottom tube of the buoy body, which can grasp the water quality changes of lakes, reservoirs and rivers, improve the early warning function, enhance the ability to cope with sudden changes in water quality, and provide a scientific basis for decision-making.

[0005] Most existing water pollution detection buoys have the detector fixedly connected inside the buoy, which makes it inconvenient to inspect and replace the detector. In addition, the existing water pollution detection buoy is easily affected by weather or animals when floating on the water, causing the buoy to tilt, thereby affecting the detection work of the buoy, and the collected data is small and the efficiency is low.

[0006] The common water quality detection buoys on the market are divided into offshore water quality detection buoys and river water quality detection buoys. Since offshore water quality detection buoys work far away from land, mobile networks cannot transmit data normally. Therefore, Beidou short message communication is mostly used. River water quality detection buoys work in freshwater areas and mostly use 4G network transmission, a single transmission method, a fixed working mode and strict environmental requirements. It cannot cover the entire inland and offshore areas, and has low communication success rate and difficult data transmission. Summary of the invention

[0041] A magnetic key 2 is docked and installed at the bottom of the lower shell cover 102 of the buoy, a connecting piece 201 is installed at the bottom of the magnetic key 2, a Bluetooth module 203 is installed at the bottom of the connecting piece 201, a multi-parameter water quality sensor 204 is installed at the bottom of the Bluetooth module 203, and the outer circles of the multi-parameter water quality sensor 204 and the Bluetooth module 203 are wrapped with an outer wrapping 207.

[0042] The main control board 108 is respectively connected to the mechanical switch 106 , the battery unit 107 , the Beidou short message communication module 109 , the 4G communication module 110 , the wireless communication module 111 , the 4G communication antenna 202 , the Bluetooth module 203 , the multi-parameter water quality sensor 204 and the Beidou communication antenna 206 .

[0048] like Figure 1 - Fig.10 As shown, the working process of a multifunctional river water quality monitoring buoy provided by this embodiment is as follows: when the buoy is working, the battery unit 107 in the battery unit provides a continuous working power regulated output for the entire buoy system, and the main control board 108 controls the power-on time of each module. When the preset time is reached, the main control board 108 controls the multi-parameter water quality sensor 204 to power on and start, and the transfer data acquisition board transmits the monitoring data uploaded by the received device back to the main control board to transmit the monitoring data to the communication module, and determines the current attitude information of the buoy based on the gyroscope, accelerometer and magnetometer built in the buoy. If the attitude information belongs to the communicable attitude range, the collected information is sent to the Beidou satellite system;

[0049] If it is not in the communication posture range, the 4G communication module 110 is started to connect to the ground data center. If the connection is successful within the specified time, the data is sent to the ground data center and the interaction with the big data platform is maintained;

[0050] If the link fails within the specified time, the data will be saved in the flash memory, and the data will be transmitted to the buoy ground data center when the program determines that the conditions for sending data are met next time.

[0051] Example

[0052] like Figure 1 - Fig.10 As shown, after the buoy is started, through data collection, 112 sends the hydrological parameters obtained by the meteorological monitoring module and the multi-parameter water quality monitoring module to the ground data center through the communication module 110, and the ground data center pushes the hydrological parameters to the water quality monitoring system cloud platform in real time. Users can obtain real-time and historical hydrological parameters through mobile terminals and compare them accordingly;

[0053] Based on the gyroscope, accelerometer and magnetometer built into the buoy, the current attitude information of the buoy is determined, and the attitude information is the pitch angle, roll angle and heading angle. If the attitude information belongs to the communicable attitude range, the collected information is sent to the Beidou satellite system;

[0054] Based on the main control board, the 4G communication module 110 is started to establish a link connection with the ground data center. If the link is successful within the specified time, the collected hydrological parameters are sent to the ground data center;

[0055] After the buoy is started, the satellite positioning module is used to receive the positioning signal sent by the satellite and calculate to obtain the location information;

[0056] After the buoy is deployed, the user can remotely connect to the buoy through a mobile terminal to obtain the latest buoy status and set the sensor to collect hydrological parameters and send data.

[0057] If both the 4G communication module and the Beidou short message module fail to communicate within the specified time, the hydrological parameters of that time will be saved in the flash storage module and sent to the buoy ground data center when the hydrological parameters are collected next time.

[0058] The battery unit 107 is threadedly fixed to the inside of the buoy lower shell 102 by a battery protection cover through screws, and is electrically connected to the main control board to provide a stable voltage output of 14.5V for the entire buoy circuit system, ensuring that the buoy can operate normally and effectively for a long time.

[0060] The main control board is the core component of the buoy, which is mainly used to receive the monitoring data uploaded by each device, control the running time of each device, and keep in touch with the ground monitoring center to realize remote data transmission. The core control chip of the main control board is the STM32L151RDT6 chip. The detailed information of the chip is as follows: 1.8V~3.6V wide voltage power supply; main frequency is 32Hz; supports multiple low power consumption modes, including standby mode, sleep mode, shutdown mode, etc., suitable for applications that need to run for a long time and have strict requirements on power consumption; has rich security mechanisms, including hardware encryption, CRC check, independent watchdog Etc.; It has high-speed embedded memory, supports up to 384KB of flash memory and 48KB of RAM, and provides powerful data processing and storage capabilities; It has standard and advanced communication interfaces: two I2C, three SPI, two I2S, one SDIO, three USART, two UART and one USB; It has one general 32-bit timer, six general 16-bit timers and two basic timers, and one real-time clock (RTC), which can count the seconds, minutes, hours, date, week, month, year details, and can control the working time of each module, thereby reducing power consumption and improving work efficiency.
