The RSL10 module is plugged into the self-made optocoupler isolation circuit board, and the entire module is connected in series with the modified target instrument (4-20mA two-wire passive digital display meter) and then connected to the 4- In the 20mA current loop, when the actual working zero current is 4mA, the target instrument displays 4.000mA in the current mode; the overall voltage drop of the circuit board of the work is 2.513V; the changed range or unit is sent to the RSL10 on the circuit of the work through the mobile APP Setting command, the target instrument (currently its own voltage drops by more than 1V) will be changed by Bluetooth remote control to change the setting state, such as switching to different ranges or displaying different measured physical quantity units, etc.
The project implementation uses RSL10 and external mechanical control structure to complete wireless control of traditional switches.
The acceleration sensing unit (RSL10+KX023) attached to the back of the door is used to detect vibration and movement to detect events such as opening the door and knocking on the door. It also interacts with the terminal through information through BLE and can view the log on the handheld terminal. Handheld terminals are also implemented with RSL10. After powering on, it automatically scans the target device and connects to it. After connecting, it obtains the time and date information of the device (which can be modified at this time), and then enters the log interface. The wireless sensing unit and the BLE terminal exchange information through the BLE connection.
The author is located in an area with a lot of convective weather and hot and humid weather. I stared at it silently, and saw that the clothes to be dried came in and out five or six times a day... Weather forecast on the mobile app? Weather warning text message? It can only be regarded as a late report. I am lazy, do it myself, have enough food and clothing...
Design and implementation of solar power generation simulation system based on TMS320F28335
The system is an intelligent tracking device based on TMS320F2812, which has the function of intelligently locking targets and automatically tracking locked targets. CPLD is used to obtain image information collected by the camera, and TMS320F2812 is used to process the image information. Median filtering, corrosion and other algorithms are used to extract target information, and then the target coordinates are calculated. The car movement is controlled through the internal PWM module of the DSP, and the target coordinates are wirelessly sent to the handheld device. Remote control device to achieve real-time tracking of targets.
The AC excitation variable speed constant frequency wind power generation experimental system was developed using TI's TMS320F2812 to complete the maximum wind energy tracking control experiment.
A hardware control circuit with TMS320F28335 as the core was designed, and experiments were conducted on the AC speed regulation SVPWM algorithm.
A stator-side direct power control algorithm based on multi-frequency proportional integral resonant controller
This design uses LM3S811 as the processor of the lubricating oil dielectric constant detection device, designs the AD5933 impedance measurement circuit, extracts capacitive reactance information from the impedance data, and calculates the change in the lubricating oil dielectric constant based on the change in capacitance to achieve lubrication control. Test the dielectric constant of oil and record the data to find out the change pattern between lubricating oil quality and dielectric constant.
The system uses TI's MSP430F149 microcontroller as the core controller. This microcontroller has a 16-bit CPU integrated register and constant generator, which can maximize the code efficiency of the microcontroller. It integrates JTAG and supports online programming; two universal full-duplex Serial synchronous/asynchronous communication interface; PWM control output; external interrupt input interface. The microcontroller is responsible for sampling the bus door opening and closing signals, turning on or off the infrared counting module, recording the number of people getting on and off at each bus stop, storing the data on the number of people getting on and off at each bus stop, and transmitting the stored data to the computer.
With TMS320F28033 as the core, it is composed of signal amplification circuit, signal acquisition circuit, data storage and processing module, system control and display module and other parts.
