Intelligent mainboard of environment protective data collecting transmitter and work method of mainboard

Abstract

The invention discloses an intelligent mainboard of an environment protective data collecting transmitter and a work method of the mainboard. The intelligent mainboard comprises a core controller; the core controller is connected with an A / D conversion interface circuit, a liquid crystal screen controller circuit, a USB interface circuit, an Ethernet port circuit, a serial port circuit and a real-time clock circuit; the A / D conversion interface circuit is connected with an analog input circuit; the analog input circuit is used to input collected analog quantity and transmits the analog quantity to the A / D conversion interface circuit; the A / D conversion interface circuit converts the uploaded analog quantity into digital quantity and transmits the digital quantity to the core controller; and the core controller further processes the uploaded data and outputs the processed data to a display circuit via an output circuit. According to the invention, different types of environment indexes collected by peripheral equipment can be calculated and displayed effectively, different input and output serial ports are provided to satisfy different monitoring requirements, users can implement secondary development on the mainboard of the data collecting transmitter conveniently, and different functions can be provided in a customized manner according to requirements.

Description

technical field [0001] The invention relates to the field of digital acquisition, in particular to a main board of an intelligent environmental protection digital acquisition instrument and a working method. Background technique [0002] Environmental protection data acquisition instrument is a new generation of powerful professional environmental protection data acquisition instrument, suitable for environmental monitoring, pollution source monitoring, etc., such as remote monitoring and data acquisition of various pollution source discharge outlets in environmental protection, air quality monitoring, surface water Water quality monitoring, etc., as well as environmental parameter monitoring such as factory internal environmental monitoring, warehouse environmental monitoring, and distributed computer room monitoring. [0003] The problems existing in the current environmental data acquisition instrument are: [0004] 1. The input and output interface is single, not compat...

AI Technical Summary

Problems solved by technology

[0004] 1. The input and output interface is single, not compatible with a variety of peripheral devices, and has certain restrictions on use;

[0005] 2. The product has poor compatibility and cannot be adjusted with the type of on-site equipment. Only the product model can be replaced or even redeveloped;

[0006] 3. In terms of data transmission, the existing environmental protection data acquisition instrument needs to be transmitted to the computer through the transmission equipment. Without a computer, it is inconvenient to use, and the data may be disturbed during the transmission process, which will affect the transmission accuracy.
