▲1. Wireless micro-vibration sensors ≥4 units, single sensor mass ≤500g, diameter (hexagonal diagonal) ≤80mm, hexagonal prism structure, product digital number silk-printed on top and side surfaces; Audio host (handheld control terminal) mass ≤1kg.
▲2. Connection Method: Sensors connect to host via WIFI, featuring wireless networking function, supporting automatic connection to handheld control terminal after startup. Control terminal can simultaneously access ≥4 sensors, adaptively adjust display ratio based on number of accessed sensors, and display sensor numbers.
3. Supports simultaneous display of detection signal strength from 4 accessed wireless micro-vibration sensors in bar chart form. Can synchronously display audio column charts of each probe and vibration frequencies received by each probe on computer terminals in remote command halls. Also supports real-time saving of detection data at computer remote data center, and playback of detection data from selected historical time periods.
▲4. System features sound restoration function, capable of real-time restoration of sounds made by persons such as tapping, scratching, etc. (not preset electronic simulated audio), and distinguishing sound types and intensities.
5. System features relative positioning function, displaying relative position and orientation of accessed wireless micro-vibration sensors and handheld control terminal (audio host) on simulated map interface of control terminal.
6. In open environment, wireless communication distance between wireless micro-vibration sensors and handheld control terminal should be ≥80m.
7. Voice Intercom Probe: Composed of speaker, microphone, 10m data transmission cable, and communication module. Supports two-way voice intercom with handheld control terminal.
▲8. Protection rating of wireless micro-vibration sensors ≥IP67, drop resistance height 2 meters.
9. Operating ambient temperature -20℃～60℃, storage ambient temperature -40℃～70℃.
10. Built-in rechargeable lithium battery, working time ≥10 hours.
11. Product Configuration: Wireless micro-vibration sensors *4, handheld control terminal *1, voice intercom probe (including 10-meter cable) *1, noise-canceling headphones *1, magnetic metal pieces and magnetic needles for accompanying data, chargers *2, carrying case *1, smart management cloud platform software (built-in) *1.
12. Device can connect to computer cloud data center, allowing remote low-latency viewing of device location, online status, operating data, and battery information via cloud. Supports same-screen display of multi-probe audio column charts. Maintenance management and reminders for devices can be realized through cloud data center, including training assessments. Detection data information can be permanently saved for later review and analysis. Provide screenshots of above functional interfaces.
13. ▲ Marked clauses require inspection reports issued by national authoritative testing institutions with CMA or CNAS certification marks. Provide query results from the "National Level Qualification Certification Obtained Institutions" or "National Quality Inspection Centers" directory on the National Certification and Accreditation Information Public Service Platform.
▲14. Intrinsically safe explosion-proof design, explosion-proof grade not lower than IIC level. Provide explosion-proof certificate issued by national explosion-proof testing institution.
