Research On Monitoring System Of Remote Multi-Point For Oil Depot Temperature

In the modern society, the storage of fuel is the lifeblood of the national economy, it related to economic construction, production and living and even social development or other aspects, however, the temperature any-time monitoring and control system of oil depot has not received due attention. Therefore, this research aims to realize multi-point remote any-time temperature detection system of oil depot.The paper based on temperature measurement technology of thermistor sensor, research for the oil tank temperature multi-point any-time detection system of special environment. The system is composed of three major components, temperature detection module, wireless communication module and data processing and display module. the temperature detection module is mainly composed of athermistor temperature sensor, unbalanced bridge, integrated amplifier, every tank can achieve64test points, according to the select hardware and correction of software, the module improve the system temperature measurement accuracy; wireless communication module uses nRF905chip as the core, realize the wireless short distance transmission; the display module developed interface on the platform of windows with VB6.0software, realized in the upper PC end multi-point temperature data any-time display, monitoring function and warning temperature alarm, it can refer to any point in the history of the temperature and the number of alarms.In this paper, according to the function of the system, have designed hardware and software of system, pass the actual test of the nonlinearity correction of thermistor an experimental verification of the calibration method of B value. The system has stable performance, high reliability, friendly interface and convenient operation, its measurement accuracy meets the design requirements. This study has the practical significance to improve the detection method of oil temperature in the future.
