Product Details

Industry background

Policy driven and smart water, electricity, and gas meters rise

Ladder water, electricity, and gas prices accelerate the popularization of smart water, electricity, and gas meters

●Ladder water price:In December 2013, the National Development and Reform Commission and the Ministry of Housing and Urban Rural Development issued the "Guiding Opinions on Accelerating the Establishment and Improvement of a Tiered Pricing System for Urban Residents' Water Use"; In November 2016, the Ministry of Housing and Urban Rural Development released the "Guidelines for the Construction and Application of Smart Water Information Systems";
●Ladder gas price:Guiding Opinions of the National Development and Reform Commission on Establishing and Improving the Ladder Pricing System for Residential Life Gas (NDRC Price [2014] No. 467)
●Tiered electricity priceNational Development and Reform Commission: Starting from July 1, 2012, a comprehensive trial of tiered electricity pricing will be implemented

Smart communities promote the intelligence of water, electricity, and gas meter enterprises

●Ningbo Water Meter and HuaweiJointly solve problems such as wireless communication technology for smart water meters and big data processing and application in pipeline networks;

●Xintian Technology and Schneider ElectricXintian Technology and Schneider Electric signed a strategic cooperation agreement on smart water solutions business;
In 2019, a total of 77.21 million smart meters and electricity information collection terminals were purchased, with an amount of up to 16 billion yuan
In September 2017, Shenzhen Gas, China Telecom, and Huawei jointly released the "NB IoT Smart Gas Solution White Paper"

Current pain points

The problems of traditional hospital meter reading

1. Low accuracy and efficiency: Traditional manual meter reading faces problems such as difficulty in entering households, high intensity, long cycle, low efficiency of manual settlement methods, and easy occurrence of errors. At the same time, most of them do not support tiered pricing and cannot obtain table side data, among other issues.

2. High operating costs: Traditional manual meter reading methods face the problem of increasing labor costs year by year, and enterprises are unable to effectively control operating costs.

3. There is a production and sales gap: errors in upstream and downstream measurement, accuracy of measuring instruments, supply environment (temperature, pressure, etc.), leakage and pipeline replacement in the pipeline network, and accuracy of meter reading can all cause a production and sales gap.

4. Difficulty in obtaining electricity: Taking water and gas as examples, most meters are deployed at the end of the supply side, and production faces the problem of difficulty in obtaining electricity. Using wired equipment for power and network supply results in high construction costs!

5. Network coverage: Smart meters are usually installed in enclosed environments, such as corridors, indoors, underground, etc. Not only are the installation environments complex, but network signals are often difficult to guarantee. Without effective network coverage support, intelligent devices become virtually non-existent

Solution Introduction

Solution Architecture

LoRaWAN remote meter reading overall solution

Solution Overview

1. Using water meters that support LoRaWAN protocol for metering and remote data transmission

2. G500 gateway is used for network coverage outdoors, and G300/100 gateway is used for network supplementation indoors

3. Reliable data transmission, network and device management through network management cloud platform and meter reading business support platform

Effect feedback

1. The water and electricity meters collect measurement data on a regular basis, and the meters can be read in real time, reducing the labor cost of manual meter reading, calculating errors, and increasing meter reading flexibility

2. Water meter battery power supply, meeting a battery life of over 6 years

3. Real time statistics of water and electricity meter data can dynamically and comprehensively grasp the energy consumption status of the community

4. 1-2 G500 gateways can cover the vast majority of the entire residential area

Technical highlight: LoRa physical transmission

LoRa physical transmission is currently the best practice for wireless meter reading

1. With a receiving sensitivity of up to -142dBm, it is thousands of times higher than 4G networks and can achieve reliable transmission within 3km in urban areas and up to 15km in suburban areas

2. Sleep current as low as 5uA, emission current up to about 100mA, ensuring long battery life of the device

3. Strong penetration ability, capable of penetrating up to 15 floors of floor slabs

4. Low module cost, economical and practical

5. In 2017, more than 10 million LoRa chips were shipped in Chinese Mainland, of which more than 80% were used in the meter industry. Its transmission stability and quality have been widely recognized and verified in practice

Technical highlight: LoRaWAN transmission protocol

LoRaWAN is an excellent network protocol for implementing meter reading services
Compared to the private LoRa protocol
1. More professional, with strong network maintenance capabilities
2. Native support for AES128 based data encryption and authentication
3. Unified standards, deploying a network that can scale numerous IoT applications
Compared to NB IoT
1. The protocol was commercialized earlier, and its application has been validated by a large number of projects
2. Network deployment on demand, more flexible, can quickly complete signal coverage for every corner
3. Lower network costs
4. Terminal devices have lower power consumption and longer battery life
5. A large number of LoRaWAN devices have been developed and commercialized
