IoT-based environmental monitoring system

Abstract

The invention relates to an environment monitoring system based on the internet of things, which is characterized by comprising a power supply module, a master control module, a wireless communication module, a sensor module and a central monitoring module, wherein the master control module is connected with the power supply module, the wireless communication module and the sensor module respectively; the central monitoring module is connected with the master control module in a wireless manner; the master control module comprises a master control core processor, a storage and interfaces; and the sensor module comprises a sensor, a signal conditioner, an amplifier, a singlechip and an interface connected with the master control module. The system dispenses with laying power lines, data communication lines and the like, has small volume and low power consumption, is convenient to install and maintain and has the equipment, installation and maintenance costs greatly lower than the costs of the similar equipment; in addition, the system uses the 3G wireless network for data communication and can provide high-speed data interaction.

Description

technical field [0001] The invention relates to an environment monitoring system, in particular to an environment monitoring system based on the Internet of Things. Background technique [0002] The main media of environmental pollution are "water, air and sound". Environmental noise is one of the important components. The control of environmental noise has received more and more attention from the state and society. The existing environmental noise detection equipment mainly includes handheld noise detectors, vehicle-mounted noise detectors, and fixed-point installation detectors. [0003] Among the existing noise monitoring and monitoring equipment, hand-held or vehicle-mounted detection equipment can only be manually operated by a single machine, and can only be viewed or stored on this machine, and cannot be connected to the Internet. Because manual operation is required, it cannot be monitored for a long time, and it cannot be monitored at special times (such as late n...

AI Technical Summary

Problems solved by technology

[0003] Among the existing noise monitoring and monitoring equipment, hand-held or vehicle-mounted detection equipment can only be manually operated by a single machine, and can only be viewed or stored locally, and cannot be connected to the Internet

Because manual operation is required, it cannot be monitored for a long time, and it cannot be monitored at special times (such as late night, etc.) or in specific locations (such as high-risk locations), and the cost of personnel used is high

Because it cannot be connected to the Internet, it cannot provide unified data within the metropolitan area

[0004] The existing fixed-point installation detectors for noise are bulky and expensive, and the installation location needs to provide power lines, data communication lines, etc., so it is difficult to distribute them in a large range and high density, and even some wireless transmission monitoring equipment adopts a point-to-point transmission scheme , the speed is low, the transmission data is single, and it is difficult to network on a large scale
