Multi-Channel Temperature Test Solution for Floor Scrubbers

In R&D validation and mass-production quality control of household smart floor scrubbers, the temperature rise characteristics of key components such as the roller brush motor, water suction motor, lithium battery pack, main control PCB (MOS/driver IC) and clean water tank heating assembly directly determine product service life, electrical safety and user experience.

Floor scrubbers form complex dynamic temperature fields under long full-load operation, roller brush stall, carpet/hard floor switching and high-temperature return water conditions; traditional single-point infrared or handheld temperature measurement can no longer meet the data traceability requirements of multi-station parallel ageing.

1. Test Requirements

Synchronous Multi-Point Monitoring

A single machine must cover 10~16 measuring points simultaneously, including the roller brush motor housing/winding, water suction motor bearings, battery pack (multiple points on cell surfaces), PCB drive area, air outlet and clean water tank heating tube; a 4-station ageing rack requires 64 channels of concurrent acquisition.

Stall/Overload Transient Capture

When the roller brush jams, the motor temperature can surge to 130~150℃ within tens of seconds, requiring a fast enough scan rate, with upper and lower limits set independently on each channel to trigger alarms.

Live Measurement with Interference Immunity

The floor scrubber drives motors and heating tubes with PWM during operation, so the instrument must support live temperature measurement (isolation voltage ≥230V) to avoid data jumps caused by common-mode interference.

Long-Term Recording and Traceability

The 300h/500h ageing test of the complete machine requires uninterrupted recording; data should be exportable to Excel for analysis and connect to the MES quality system.

2. Equipment Selection and Configuration (Recommended Solution)

64-Channel High-Density Acquisition with Wide Temperature Coverage

Compatible with J/K/T/E/S/N/B/R thermocouples and Pt100/Pt1000 RTDs, with a test range of -200~1800℃ (K-type accuracy ±0.8℃) and 0.01℃ resolution; battery/PCB measurements and motor stall measurements (K-type wide range) in floor scrubber scenarios can be completed with the same instrument.

High-Speed Scanning and Real-Time Display

It scans all 64 channels in 500ms, and the mirror touch screen displays values, curve graphs and bar charts simultaneously, with high/low/average values shown on one screen for quick judgement during line patrol.

Automation Interfaces and Large Data Storage

Standard RS232C + USB + LAN + USB flash drive interfaces and ATS45 data acquisition software support SCPI/MODBUS connection to PLCs and host computers; built-in 64G storage keeps data safe through 500h of continuous ageing, and data can be moved in real time to a USB disk.

Smart Sorting and Live-Test Safety

Each channel is calibrated independently with independent upper and lower limit thresholds, and the comparator outputs GO/NOGO directly to drive sound-light alarms or sorting IO; fully isolated live testing with 230V AC/350V DC isolation voltage allows safe live temperature measurement while the floor scrubber runs under load.

3. Summary of Core Advantages

High Efficiency and High Throughput

A single AT4764AV covers 3~4 complete machines (10~16 measuring points each) for simultaneous multi-station ageing tests, significantly reducing the temperature rise test cost per unit.
