Background/Objectives: The drones became a representative item in the IoT era. However, there is no drone pilot test system that can safely train this in the education field. Drones have very dangerous structural problems, so it is very necessary to practice them easily. Therefore, it is necessary to develop a system that can control the drones safely and easily while controlling them.Methods/Statistical analysis: In this paper, we will develop software for controlling a dedicated board platform that can securely perform ground testing by mounting four drones of motor and drive on a board (PCB). To this end, we supported various control IMU (Inertial Measurement Unit) boards for attitude control by using sensor which is the core technology of drone flight control. Also, Acceleration Data, Angular Velocity Data, Earth Magnetic Field Data, and Atmospheric Pressure Data for maintaining the altitude were used for the drone flight.Findings: In the implemented central control system, the AT chip is built in and designed to perform all control related to the flight of the drone. In addition, since it is an embedded system, we have programmed the attitude control using the sensor, the motor output setting, and the controller connection information. The CPU required for drones control can be replaced with various types of controllers besides Fno Arduino, UNO, Muiltiwii. For this purpose, the main PCB is designed so that the power supply terminal can be used for each CPU. Finally, it was developed as a setup program to correct the sensor and output of the drone.Improvements/Applications: The system implemented in this paper can easily control the drone. In addition, acceleration, angular velocity, geomagnetic field, air pressure sensor, GPS, etc. necessary for drone control can be utilized by stabilizing the initial set value. In other words, the zero point of the sensor can be captured and the signal appropriate to the current state of the drone can be stored in the processor.

Measurement And Control

In this paper, the design scheme of a Measurement and Control(M&C) system based on AT91RM9200 is proposed. For expanding the test functions, based on the AT91RM9200 control platform the GPIB interface is added in the platform. With the EMAC interface, the automatic test function on multiple communication channels is realized on the GPIB test bus and Ethernet. In this paper, the Modular architecture is used to design the hardware platform. While in the design of the software, the real-time multitasking function of RTOS is combined with the task processing methods corresponding to the interruptions to make the design , building and reusing of tasks more convenient. So that the whole test system can be more common and scalable.

VXI or PXI modules based on embedded computers are playing a significant role in test systems for both agricultural and commercial applications. In an Agricultural equipments remote diagnosis and Maintenance ATS (automatic test system), we applied ARM based VXI modules to developing an equipment called Portable Maintenance Aid Equipments (PMAE) as well as an Ethernet-based measurement system which solved a sticking point of this large-scale ATS. The main testing system is designed as a large-scale integrated test system that will perform automatic test for faulty LRUs (Local Replaceable Unit), and faults will be isolated to SRUs (Shop Replaceable Unit). PMAEs could cooperate with the main testing system in realizing remote measurement and control through virtual instrument (VI) technology, thus the localization veracity of faulty LRUs and cables could be greatly improved. ARM based embedded system was used to realize 0－slot controller as well as some dedicated test modules. It could offer maximum performance and the most compact size because they are installed directly into the VXI mainframe. Test results indicated good performance of this scheme, thereby greatly augmenting diagnostic capacity and efficiency of the Agricultural equipments remote diagnosis and Maintenance ATS.

Isolation Performance

The vehicle-mounted equipment is easy to be disturbed by external vibration excitations during transportation, which is harmful to the measurement accuracy and performance of the equipment. Aiming at the vibration isolation of the vehicle-mounted equipment, a semiactively controlled quasi-zero stiffness (QZS) vibration isolator with positive and negative stiffness is proposed. The vertical spring is paralleled with a magnetorheological (MR) damper, and the semiactive on-off control scheme is adopted to control the vibration. The analytical expression of the isolator’s displacement transmissibility is derived via the averaging method. Then, the vibration isolation performance under different road excitations and different driving speeds is simulated and compared with the uncontrolled passive QZS vibration isolator. In addition, the mechanical structure of the semiactive QZS isolator is designed and manufactured, and the test system is built by LabVIEW software and PXI embedded system. The isolation effect of the semiactive QZS isolator is verified through test data. It is found that the proposed semiactive QZS isolator shows excellent vibration isolation performance under various road excitations, while the passive QZS isolator is effective only under harmonic excitations. The vertical acceleration of vehicle-mounted device can be decreased over 70% after isolation, and the vibration isolation effect is remarkable. The design idea and research results of the semiactive QZS isolator may provide theoretical guidance and engineering reference for vibration isolation.

Geothermal Parameters

A test system for geothermal parameters is designed with S3C2440, it is an embedded system which can friendly display the test values and geothermal parameters in real time. The test theory is based on heat balance principle. A heater produce heat to induce into the ground through U buried tube. When equilibrated, the heat from the heater is equal to the heat taken away by ground. The heat taken away by ground is measured by testing the temperatures of two ends of U buried tube and the water velocity flowing through tube; the real produced heat by heater is measured by testing the current and voltage of heater. The heat power can be changed by controlling solid-state relay with PWM. The driver programs in S3C2440 for the testing sensor of temperature, current, voltage, water flow and PWM are designed with Linux; the testing values are real displayed and can be saved which interface is designed with OSS QT4.
