The Remote Monitoring System Of Medical Equipment Environmental Parameters Based On STM32

In the development of medical technology, a large number of advanced, precision, complex medical equipment assemble to the hospitals, but most hospitals lack of the regulation of equipment and professional maintenance technicians, the use of equipment risk and the incidence of adverse events showed a trend of rising year by year. The remote monitoring system of the medical equipment environmental parameters in this paper, provide the basis for medical staff to grasp equipment running status to reduce the adverse events of medical equipment, also provide a simple basis for equipment maintenance.First of all, introduced the main monitoring objects and related monitoring technology in this paper, analyzed the goals and principles of system design, combining with the actual, proposed the system overall scheme. Second, according to the overall scheme, monitoring environmental parameters such as leakage current, magnetic field intensity, infrared temperature and acceleration, selected the sensor and designed the interface circuit. Combined with the STM32 chip instruction, built the minimum operation system by designing power system and clock system of STM32, and designed other related interface circuit for the hardware platform of whole system. Then, though programming software and developing PC drive, the lower computer realized the data acquisition and the communication with upper computer, the upper computer realized the data processing, display, alarm and remote monitoring. Combined with the hardware platform, realized the remote monitoring of the medical equipment environmental parameters. Finally, tested the system and analyzed the result, calculated measurement accuracy of each parameter.After the system test, all the modules realized the corresponding function, measurement precision meet the design requirements. The system has advantages of low costing, more measurement parameters and easy for carrying, and you can measure more parameters by extending the additional modules and upgrade the software. The remote monitoring system avoids one man with one set of medical equipment, reduced the workload of medical staff, the system has strong application significance.
