(1) Technical Requirements for Meter Reading Box (IoT)
1) Communication function: The IoT meter reading box exchanges data information upstream with the system server through the mobile 4G IoT network; The downlink channel passes through RS485 busCommunicate with remote water meters and automatically collect data from all water meters under its jurisdiction.
2) Power supply: Adopting a dual power supply mode of external power supply and battery. The meter reading box contains a battery that can be replaced. Under the condition of sending and receiving data once a day, it can be used for 25 years under full load testing, ensuring that it can work for more than 6 years without the need to replace the battery.
3) Setting function: can set initial parameters and reading intervals; And it has the function of preventing unauthorized personnel from operating.
4) System management information collection function: automatic collection through busElectronic remote water meterAccumulate water volume, work status and other data information to truly achieve meter reading and monitoring automation.
5) The meter reading box adopts a low-power design as a whole, and data storage is required to be retained for more than 1 year.
6) The meter reading box is equipped with a manual reading function and a reserved manual reading interface. The manual reading function is directly integrated with the system software function.
7) Power management function: It can automatically detect and report the working status of the system power supply.
8) Total error rate of data reading: The system guarantees 100% error free data reading.
9) System stability: Open or short circuits in any position of the road in the system cannot cause the water meter to lose data. Bus short circuit has no impact on interface circuit. Unexpected damage to the interface circuit does not affect other functions of the instrument.
10) System reliability: Under normal working conditions, the system can operate without faults for 6 years.
(2). Technical requirements for solar power supply system
1) The solar panel is a 12V50W flexible solar panel.
2) Solar controller: 12V10A, must support dual power supply of solar energy and DC power, adopt floating surge mode for the battery, and the controller has overshoot and overdischarge protection, short circuit protection, overcurrent protection, open circuit protection, and reverse connection protection
3) The battery adopts lithium battery.
4) Surge protection module: prevents large surges, sudden abnormalities, and protects equipment functions
5) Lightning protection module: plays a role in lightning protection, protecting equipment from damage caused by lightning strikes
6) Air switch: controls the power circuit, plays a role in short-circuit protection and mains overcurrent protection
