YD360 wireless monitoring: fifteen-page source
Piezoelectric/Zigbee hardware description and the v1.2.0 monitoring-software workflow, including FFT and logs.
On this page
This fifteen-page source differs from the three-page MEMS/LoRa source: it describes piezoelectric/Zigbee hardware, 800 spectrum lines, two lithium batteries, 36 × 60 mm and 400 g. Hardware release applicability is unconfirmed. Software v1.2.0 and the closing date October 20, 2019 apply to the software section, not necessarily the hardware. Ethernet-to-server communication was described as unfinished.
Measurements and sensor hardware
The system monitors rotating-machine vibration and temperature, sends data to a computer and provides condition indications with normal status and two alarm levels. The source describes analysis for imbalance, structural looseness and misalignment, and refers to GB/T 6075.3-2001 vibration-severity assessment.

Battery life is a source claim without a stated duty-cycle test. Smartphone synchronization is custom.
Collection and upload schedule
The default collection interval is 10 minutes. Overall values upload every two hours by default, and spectra upload once per day. Upload intervals are configurable. When an alarm occurs, overall values and the spectrum are uploaded.
Do not substitute the schedule or specifications from the three-page YD360 source. That source lists different intervals and hardware.
Sensor mounting and controller setup
Sensor mounting choices are an M8 × 5 mm threaded hole, adhesive or a magnetic base. The wireless controller can be clamped/bolted to a pole or screwed to a fixed plane; the source recommends mounting it as high as possible. Its connection layout is graphical, so obtain the drawing for the supplied controller before wiring.
The controller is specified for USB or external 5 V DC power, 150 m open line-of-sight transmission, a −20 to 60 °C operating environment, and dimensions of 160 × 120 × 35 mm excluding the antenna. USB communicates with the acquisition computer and wireless communication serves the monitors. Ethernet-to-server communication is explicitly described as still being completed.
The power indicator stays green after power is connected. The link indicator stays green when powered and connected to a network switch. Communication and status indicators illuminate during device data transfer; status also lights when commands are sent or data is uploaded. They go out after the exchange.
Manage sensors and groups in software v1.2.0
The software supports adding, deleting and renaming sensors, viewing online state, assigning sensors to groups and clearing sensor history. Groups can be added, renamed, moved within a nested structure and deleted. These commands are accessible through a context menu.
To configure a device, select that individual sensor and open its settings. Documented fields include upload interval, sampling rate, alarm threshold and danger threshold. The configuration is sent to the selected sensor and saved. The manual does not establish that editing a group applies a sensor configuration to every member.
Historical-data clearing is distinct from clearing a live monitoring display. No history-deletion recovery procedure is documented.
Query historical, alarm and danger data
For history, choose a start and end time or a query period. Run the query, choose the number of rows per page and page through the records without changing the query conditions. Export saves the current page as an Excel spreadsheet.
Historical line plots show velocity, displacement and acceleration. Select X, Y, Z or the combined value as required.
Alarm and danger records have their own query views with the same time-range/period selection, paging and row-count controls. Export in each of those views also applies to the current page. The manual does not describe a bulk export of every page in one action.
Live monitoring and FFT review
Live monitoring provides Start, Stop and Clear controls. Use the real-time line plots for velocity, displacement and acceleration and choose the required X, Y, Z or combined component.
To inspect stored FFT results:
- Set the start and end times for the FFT query.
- Query and select an FFT result.
- Display the selected result.
- Adjust the horizontal and vertical viewing angles for inspection.
The source illustrates these controls but does not document advanced spectrum algorithms, diagnosis thresholds or numerical export formats for FFT results.
Logs, messages and host requirements
The log view lists log files. Select one to display its content, open the containing directory when needed, and refresh the content to see updates. Some user operations create messages in the message list; that list can be cleared.
The historical software requirements are an Intel Core i3 or higher, at least 4 GB RAM, at least 5 GB free storage, a 1 or 2 GB discrete graphics card, Windows 7 SP1 / Windows 8 / Windows 10 and DirectX 9.0c or later. These describe the recorded software edition, not a current compatibility guarantee.
The guide lists custom launch logos, application names and other agreed custom work. Such entries are options rather than confirmation that arbitrary custom features are present.
