关于无线环境监测模拟装置的英文翻译

英文

Wireless environmental monitoring through wireless mobile communications (GPRS / CDMA) and the Internet (INTERNET) seamless docking with real-time data acquisition, remote transmission, remote storage and web publishing functions, may facilitate the realization of a variety of remote site monitoring and management, through analysis of data mining and the combination of knowledge and experience of experts can provide remote diagnostics of the relevant objects and control management. Wireless remote environmental testing real-time monitoring system integration technology, modern sensor technology, wireless communication, computer network technology as a whole, from the structure and composition was divided into three parts: the terminal acquisition transmit modules, the server receives storage module, Web-based data dissemination and analysis modules.

Wireless monitoring and control is a remote control unit terminal devices, monitoring and control terminal set A / D functions and I / O functions as one, is responsible for on-site signals, industrial equipment monitoring and control. DTD110 RTU series wireless module is through a long period of Xi'an Datai electronics companies to explore and develop with feedback from users of wireless telemetry remote terminal equipment. The module uses 16-bit low-power

16-bit MCU control, and DTD465 series wireless module with wireless telemetry and remote control. Provides 4 analog input and 4 analog outputs; or 4-way switch input, 4-way switch output. Analog can be a 0 ~ 5V voltage signal, it can be 4 ~ 20mA current signal. Industrial field transmitter can capture a variety of analog output, digital signal; to output control signals to control the relay output.

There is also a remote wireless environmental monitoring simulation device. For unattended monitoring of remote environmental issues, an experimental simulation system design. Modular design, mainly by the energy harvesting module, the control center module, the sensor monitors the node module, the wireless transmission module and LCD display modules and other components. Monitoring center and the monitoring node with AVRAtmega16L microcontroller as the control and monitoring of environmental monitoring nodes encoded by amplitude modulation signal from the wireless transceiver module sent to the monitoring center. Environmental monitoring by the energy harvesting modules supply nodes, without replacing the battery. The system is low power consumption, flexible configuration node, simple structure, can achieve the temperature, humidity and light intensity monitoring, wireless and digital display.

Simulator wireless environmental monitoring on the instructions there are so few parts. 1. Monitoring and detection of the terminal nodes with a circular air core coil antenna with a diameter of less than 1mm enameled wire or wire insulation jacket made of a tightly wound 5 turns. Coil diameter (3.4 ± 0.3) cm (One battery can be used for skeleton). Medium between the antenna coil air. Wireless carrier frequencies below 30MHz, modulation custom. Terminal node and detection monitoring shall not be used other than the provisions of the antenna coupling outside. Wireless transceiver circuitry to be made, not by the wireless sending and receiving finished module. Whether the changes in illumination, the method used to achieve occlusion photoelectric sensor. 2. Play some of the basic requirements to be in the detection delay and detection range to meet the requirements under the premise implementation. 3. Testing the detection of the node power consumption of nodes in Figure 2 shows the distribution map, keep a distance D + D1 = 50cm, by measuring the battery supply current detection node A to estimate the power consumption. Current test circuit shown in Figure 3. The figure for the filter capacitor capacitance C, current meter with 3 ½-digit multimeter DC current file and read the normal work of the maximum display value. If the D + D1 reach 50cm, this item is not tested. 4. Body of the report should include the design of the overall system block diagram, the core circuit schematic, the main flow, the main test results. Complete circuit diagram, it is important to use accessories given source.
