Wireless intelligent watering system for municipal roads and highways

With the rapid development of my country's economy and the acceleration of urbanization, environmental pollution is facing increasingly severe challenges. A city's road surface is clean and dust-free. It is not only an important reflection of the city's appearance, but also a major livelihood issue that reduces pedestrians from inhaling harmful gases and endangering their health. For this reason, local governments attach great importance to road dust removal work and invest a lot of money to purchase various types of dust removal equipment. vehicles, improve the service quality of sprinkler operations, and try to solve the problem of sprinkler services to the greatest extent possible.


But can the government's great attention and large investment of funds really solve the problem of road dust removal? On the surface, it can indeed be seen that the number of sprinkler truck operations has increased, and dust suppression has also played a certain role, but some problems have also arisen:
1. Affect road traffic and make road congestion more serious;
2. The number of traffic accidents increases;
3. Most of the sprinkler trucks are fuel vehicles, which increases CO2 emissions;
4. Cause disturbance to residents during operation and cause dissatisfaction among residents.

So how can we achieve the purpose of dust removal and haze reduction while avoiding creating new problems during the operation? TSC Smart uses "black technology" to teach you what to do. In view of China's current road and traffic conditions, Beijing TSC Smart uses Lora Internet of Things wireless communication, wireless electric valve control, wireless air quality sensor collection, air temperature and humidity (PM index) polling control, and smart municipal big data management platform, etc. This "black technology" independently developed this Internet of Things intelligent water sprinkling, dust removal and haze reduction system.

The TSC Smart intelligent control system integrates major components such as intelligent gateways, wireless solenoid valve controllers, and wireless air temperature sensors based on the cloud center. The devices communicate using the LoRa transmission protocol and can be independently networked through the controller to solve the problem. This solves the problem of long distance and high cost of belt highways. The system also sets a temperature and humidity value, and then after analysis and processing by the cloud platform management software, the green belt valve can be automatically opened or closed. Through the three modes of remote timing, remote linkage and remote switch, a mobile phone can realize intelligent control of wireless automated agricultural irrigation.


Wireless intelligent watering system for municipal roads and highways

1.Intelligent gateway

The main function of the Smart Network gate (smart gateway) independently developed by TSC Smart is to perform control operations or analyze data. It can realize localized calculation and control. It can be used when data cannot be uploaded temporarily or the user control terminal cannot be used. In this case, it can automatically control and start corresponding equipment such as solenoid valves, water pumps, fans, etc. through intelligent autonomous learning and calculation based on real-time data and historical records collected by various sensors. You can upload or receive instructions with the cloud center in the form of GPRS, WIFI, and RJ45; it is connected to the data collection equipment and control equipment through LPWAN low-power LORA communication without paying additional fees. It can be powered by mains electricity or solar energy.

2.Wireless solenoid valve controller

The wireless intelligent sprinkler system consists of a wireless air temperature and humidity sensor, a wireless Lora electric valve controller for wheel irrigation, a DN25 electric ball valve and a special intelligent retractable sprinkler head (with a pressure of not less than 0.8MPa). The nozzle can be wirelessly controlled and sprayed every 30 minutes. The installation process of the control system does not require any work such as slotting, wiring, or buried pipes, which greatly reduces the difficulty and cost of construction in municipal projects.

3.The first intelligent pump room

The first intelligent pump room is composed of frequency conversion control cabinet, wireless Lora water pump control module and other equipment. It not only ensures the stability of water supply pressure during road sprinkling, but also protects the booster pump. At the same time, users can realize control through mobile APP or computer. Remote intelligent control.

System Features

Ease of project transformation

All control equipment in the entire IoT intelligent sprinkler dust removal and haze reduction system adopts Lora wireless communication, which has long transmission distance and strong penetration. No additional slotting or wiring is required. As long as there are water pipes, it is suitable for on-site modification. At the same time, it adopts Wireless will also greatly reduce post-maintenance costs.

Superior equipment performance

The wireless Lora intelligent gateway (the core of the system, which interacts with the cloud center through GPRS in the uplink and communicates with the controller and sensors in the downlink through Lora) has independent transmission and acquisition channels (2 to 4 channels), which can effectively avoid signal transmission and reception. A collision occurs. At the same time, it has 32 different assignable channels and supports the mobile APP to modify the device frequency online, which greatly improves the anti-interference ability of the system. The latest Lora wireless networking method adopted by the system uses star networking between intelligent gateways and nodes (control equipment, sensing equipment), and the transmission distance can be stable at 500M-1400M in urban areas. Both the passing equipment and sensing equipment can have IP68 protection level.

Improvement of system mechanism

The system can be equipped with various sensors such as air temperature and humidity, PM2.5, PM10, etc., and supports real-time display on a large LED screen. It has four control modes: manual, timing, automatic and polling control, which can meet the needs of users in different situations. The mobile APP has standard mode and advanced mode, which managers can switch freely, and is suitable for managers of different ages. Supports simultaneous alarm mechanism for mobile phone SMS and WeChat multiple users. Supports daily water consumption statistics, making the usage of water resources clear at a glance. It can be seamlessly connected to the smart city management platform and provide valuable water data for the operation of smart cities.
