Solutions for remote monitoring project of community direct drinking water system

      NB-IOT wireless intelligent instrument used in the case of remote monitoring project of community direct drinking water system:

      Direct drinking water, also known as healthy living water, refers to water that can be directly consumed without pollution or degradation, meets the physiological needs of the human body (contains beneficial mineral elements similar to the human body), and has a weak alkaline pH. Long-term drinking of direct drinking water is very beneficial to human health, and the appearance of direct drinking water is clearer than ordinary drinking water, and the taste is better. In addition, the economic cost of direct drinking water is much lower than that of ordinary drinking water, so direct drinking water project appeared. The direct drinking water projects include community direct drinking water, campus direct drinking water, real estate direct drinking water, direct drinking water in public places, direct drinking water in office buildings, direct drinking water in hospitals, etc.

      Direct drinking water is generally through the quality of water supply to users directly. Separate water supply, that is, according to the different needs of people in life, the tap water provided by the municipal government is domestic drinking water. The domestic water in tap water is separated from the direct drinking water, and a pipe network is set up. The tap water is further processed by a special process that can become directly drinkable pure water. And then it was exported to households through food sanitary pipes to achieve drinking water and domestic water quality and diversion, and to meet the requirements of high quality, excellent use, low quality and low use.

      Direct drinking water can also be directly purified through the water purification equipment at the user terminal, and activated, energized, and treated by a purification system that simulates natural water, then directly output drinking water that meets national standards. When the pure water is output to the residents through the pipeline, the water supply pressure must be within its normal range, and cannot be too high or too low. If it is too high, it may cause the pipeline to burst. If it is too low, there is not enough pressure to transport drinking water to the residents. And the water quality of its water supply must meet the standards set by the state. Therefore, it is necessary to monitor the pressure and water quality of the pipeline.

      Most pressure sensors nowadays have to watch their pressure values until now, and the water quality must be regularly checked, which consumes too much manpower and material resources and is not managed. It can now be combined with sensor technology and Internet of Things communication technology to remotely monitor the pressure of the pipeline, water quality, pipeline valve opening and closing, etc., and can dynamically monitor and stereoscopically display the pipeline status of the networked unit through the PC computer and mobile phone APP system. The pressure and water quality of the pipeline are detected in real time to ensure that the pressure of the pipeline is within the normal range, the water quality complies with national standards, and stable and safe delivery of safe and qualified direct drinking water to the user.

      NB-IOT wireless intelligent instrument can solve this problem well. NB-IOT wireless intelligent instrument is composed of wireless pressure sensor, temperature gauge, water immersion transducer, wireless liquid level and water quality gauge. The instrument is installed in each fire water system, and the data such as pressure, TDS (water quality), liquid level, temperature, gas, etc. can be monitored in real time. Data can be transferred to the IoT cloud platform (currently supports several major IoT platforms such as telecommunication platforms, mobile onenet platforms, Huawei platforms, TLINK platforms), and data can be viewed on computers and mobile phones. When the data monitoring is abnormal, the smart meter will immediately send an alarm message through WeChat, SMS, phone, email, etc., so that the staff can make specific countermeasures. In addition, the smart meter has a built-in lithium battery for power supply and can work for more than five years, which solves the trouble and worry of frequently changing the battery.

    The pressure sensor of the NB-IOT wireless smart instrument has its own historical data storage function and supports the continued transmission of historical data breakpoints. If the network interruption occurs under special circumstances, after the network is restored, the smart instrument will be in the first place transfer historical data to the IoT cloud platform to avoid data loss and other phenomena. The smart meter itself also comes with saved data and can be exported with USB at any time. Data is saved on both sides, which is reliable and safe.

      In addition, the NB-IOT wireless intelligent instrument can meet the requirements of harsh working conditions such as moisture resistance, waterproof, explosion-proof, dust-proof, and anti-soaking. The pressure sensor has high temperature stability and time stability, has a 200% FS overload pressure design and corrosion resistance and impact resistance 316L isolation diaphragm, and can be in direct contact with most media.

      After installing Topray NB-IOT wireless intelligent instrument in the pipeline of the community direct drinking water system, in addition to the pressure and water quality data directly displayed on the display interface of the wireless pressure gauge, the staff can also use the IoT cloud platform or WeChat public account , WeChat applet to remotely monitor and configure the binding device. Once the data exceeds its limited range, it can be alarmed by the set method. The alarm methods include WeChat, SMS, voice, and mailbox. This ensures that the staff can monitor the pressure and water quality of the pipeline at any time, thus avoiding the situation where the pressure of some pipelines is always too high or too low or the water quality is unqualified, saving manpower and material resources, and certainly giving a qualified and healthy guarantee for direct drinking water.
