Automatic observation system for water and sediment

【Automatic observation system for water and sedimentEquipment Introduction:
The runoff sediment monitoring instrument for the runoff community is developed using the latest international CCD image sensor and Siemens infrared sensor. The online sediment flow monitor/runoff community sediment flow monitor adopts ARM technology, which has high reliability and strong stability, and is more cost-effective than the community runoff process observation instruments produced by peers using 8-bit microcontrollers and photoresistors!

【Automatic observation system for water and sedimentEquipment principle:
The runoff sediment monitoring instrument for runoff communities is mainly used for real-time online observation of small flow runoff community soil and water conservation monitoring data under natural rainfall or artificial simulated rainfall conditions. In the same community, according to the requirements of the number of weirs, data on rainfall, runoff flow, sediment content, soil erosion content, and other factors can be provided for multiple weirs channels in the runoff community. The automatic monitoring instrument for the production process in this community has taken into account the inaccurate measurement accuracy of peers in its research and development and production. Therefore, the sensor part has been modified into a set of transmitting, three sets of receiving, and weighted evaluation algorithms, making our community's production process observation instrument have high collection accuracy. At the same time, advanced 32-bit ARM technology is adopted, which makes the system run faster and more reliable than the 8-bit 51 microcontroller used to make the community flow process observation instrument.
【Automatic observation system for water and sedimentEquipment performance:
1. 24/7 unmanned operation, with ultrasonic and photoelectric sensor integrated technology for automatic data measurement.
2. The main control machine for work management data collection and storage can locally store a large amount of data, which can be downloaded on-site through RS232, RS485, and CAN interfaces. The CAN interface communication can reach up to 10KM.
3. It has the function of real-time monitoring and displaying the dynamic process of various measurement parameters, as well as downloading curves and historical data on the upper computer.
4. It is possible to freely set the sampling frequency and adjust the clock data on the data management host on site, thereby achieving complete time consistency.
5. It has GPRS wireless networking function, and if several communities are not in the same area, it can be networked for comprehensive monitoring.
6. Adopting 19264 dot matrix LCD and button operation mode, the human-machine dialogue is simple and convenient.
7. Adopting ARM technology enables high acquisition accuracy, fast computation speed, and extended lifespan.
