[Abstract]:With the promotion of the construction of the Internet of environmental protection, China will build a three-dimensional and omni-directional environment monitoring system in the period of 12th Five-Year. Based on the mobile data transmission application as the target, and relying on the mobile network with the largest wireless coverage area, an embedded device for real-time monitoring of data acquisition is designed, which is the Tianjin City It provides technical support to the national energy conservation and emission reduction, the real-time monitoring of the key pollution sources and the emergency monitoring and treatment of major environmental pollution events. The project proposed the design scheme of the data collection and transmission instrument for environmental protection special pollution sources based on ARM11, and the data transmission standard of the "on-line automatic monitoring and control (monitoring) system of pollution sources" issued by the Ministry of environmental protection of the State Environmental Protection (HJ/T) 212) and the technical requirements of the "on-line automatic monitoring and monitoring (monitoring) data acquisition and transmission instrument" (HJ 477) as the design standard, and the establishment of the Tianjin environmental protection network as a long-term vision.
The ARM11 based environmental data acquisition and transmission instrument for pollution sources has the following characteristics:
1, based on the new generation of Samsung S3C6410 processor, the ARM platform is constructed, and the auxiliary A/D sampling module is designed and developed, which can collect 8 channel analog (4mA~20mA current input) and reach a resolution of 12 bits.
2, by expanding the chip, 5 RS232 (or RS485) digital input channels can be used to connect monitoring instruments to achieve two-way transmission of data and commands.
3, at the same time, it supports two transmission modes of wireless and wired network, and the GPRS network transmission is realized by Siemens MC39i module, and Ethernet transmission is realized by DM9000 network chip.
4, the power module is designed by ourselves, which realizes the function of power supply of external power supply and standby battery, and meets the requirements of national standard HJ 477 "for at least six hours after the external power supply is cut off."
5, on the basis of customizing Windows CE embedded operating system, the communication protocol (national standard HJ/T212) and human-computer interaction function of embedded software are developed on the basis of software implementation.
6, the design introduces the SQLite technology to build the pollution information database on the embedded system, and provides reliable and efficient data sources for the future development of the cloud computing application of the environmental protection network.
The TY-001 model of the source data acquisition and transmission based on the above scheme has achieved small batch production. The prototype can be successfully butted with the analog / digital interface with the CEMS system and the water quality monitoring instrument, and the data collection is stable and reliable. At present, the prototype has passed the EMC of the Tianjin quality supervision and inspection station, the high temperature fatigue test and so on. At the same time, the instrument accuracy and communication protocol have also passed the identification of the China environmental monitoring station. After the last MTBF (60 day failure continuous running time) test passed, the qualification certificate of national environmental protection products can be obtained and formally entered the domestic market.
