Projects
Vibration Measurement System:
I have been working on a vibration measurement system for vibration screens. It includes sensor nodes, transceivers, and gateway products. I have focused on developing sensor nodes and transceiver products. Essentially, sensor nodes measure vibration, downsample it, and then apply some calculations. Snippets of raw data and calculated data are sent through BLE to transceivers. Transceivers gather data from multiple sensor nodes and send it to the gateway over TCP and CBOR protocols. They also utilize PTP for timesync between transceivers and a custom timesync protocol over radio. Transceivers have an mDNS server for gateways to find connectable transceivers in the network along with their service info, such as IP address and port number. Both products are developed with the Zephyr RTOS.
Keys: Zephyr, TCP, CBOR, PTP, BLE, mDNS, nRF5340, Ethernet, FOTA/Bootloader, Low power, Timesync, etc.
Real-Time Locating System for Mines:
This system comprises three main devices: Concentrator Gateway, Anchor, and Personal Tag. Tags periodically transmit a package containing the tag's unique ID. Anchors listen for these packages, collecting them with RSSI. Anchors are connected to each other and to the concentrator gateway in a chain structure. The communication interface between anchors and the concentrator is CANBUS. The concentrator gateway sends a tag info request message to each anchor, collects tag information, and sends it to the server via TCP/IP over Ethernet. I have designed the entire system. There are seven different products in this system, I have developed all hardware and most of the software.
Keys: TCP, Ethernet, CANBUS, SPI, RF, FTP, Bootloader, Low power, ATEX, etc.
Furniture Lift Automation:
In this project, the controller reads two encoders in quadrature mode and calculates the position, speed, and acceleration of the furniture lift platform. The controller then calculates the proper valve signal to maintain constant acceleration. The controller also includes a wireless communication system. I designed three different hardware components and developed their embedded software: hand remote controller, platform remote controller, and main motion controller.
Keys: Motion control-PID, RF, Low power, Battery Management, etc.
