A kind of environment monitoring data adapter based on pc104 bus

Abstract

In order to overcome the problems in the prior art that the interface types of detection instruments are various and the data formats are not uniform, and thus inconvenient for communication and control, the present invention provides an environmental monitoring data adapter based on PC104 bus, including: system board, total communication Board and several sub-communication boards, the system board is the main control part, the main communication board is responsible for data transmission, the sub-communication board is responsible for adapting the interfaces of various environmental monitoring instruments, and the system board, main Both the communication board and the sub-communication board are connected through the PC104 bus. On the basis of retaining the original hardware, it can configure and maintain on-site testing instruments by flexibly adding or subtracting interface modules and drivers; it has wireless network functions, is easy to install, and can quickly access the Internet; Unified management and control of on-site testing instruments.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to an environment monitoring data adapter based on a PC104 bus. Background technique [0002] Through the analysis of domestic environmental monitoring adapter products, the price is its main advantage, but the interface type and quantity of the instrument are relatively simple and limited. With the rapid development of my country's environmental monitoring, new testing content, testing technology, and testing methods are constantly updated. Once a new interface testing instrument is added, the original adapter cannot meet the needs of interface adaptation. Therefore, it is necessary to develop new data interfaces and drivers, resulting in frequent changes of adapters, which is not conducive to the sustainable development of environmental monitoring. foreign [0003] Environmental monitoring adapter interface types and quantities are relatively rich, but exp...

Problems solved by technology

However, environmental monitoring is often carried out in harsh field environments, and GPRS / GSM networks cannot cover it. Even if it can be covered, the operating costs are expensive; while wired network wiring costs are high, mobility is poor, technical difficulties are high, and anti-interference and anti-lightning capabilities are weak. , maintenance costs are expensive, these are the difficulties that cause adapter networking
