Abstract

The present invention discloses a wetland environment monitoring data acquisition circuit. The circuit comprises: a power supply circuit, a sensor signal conversion circuit, a main control circuit, anRTC clock circuit and an LCD screen control circuit. The sensor signal conversion circuit includes a USART conversion circuit, a CAN bus conversion circuit, a 485 bus conversion circuit, and an AD conversion circuit. The RTC clock circuit provides a clock signal to a main control chip in the main control circuit through a clock chip. The AD conversion circuit includes an analog to digital conversion chip. The USART conversion circuit includes a serial port chip. The CAN bus conversion circuit includes a CAN bus driver / receiver and a first surge suppression module. The 485 bus conversion circuit includes a 485 bus driver / receiver and a second surge suppression module. The circuit can quickly collect various environmental parameters in the wetland, and thus can carry out targeted intervention on the wetland environment.

Description

technical field [0001] The invention belongs to the technical field of wetland environment monitoring, and in particular relates to a digital acquisition circuit for wetland environment monitoring. Background technique [0002] Known as the kidneys of the Earth, wetlands filter and clean drinking water and provide habitat for many iconic species such as cattails, cranes, alligators and more. Coastal wetland resources have played an important role in the social and economic development and ecological environment protection of my country's coastal areas, produced huge social and economic value, and made positive contributions to the economic take-off of my country's coastal areas. However, with the development of society and economy in coastal areas, many problems have been exposed in the development and utilization of coastal wetland resources. Unreasonable development and utilization have brought some irreparable losses and impacts on coastal wetland resources. The main pro...
