Avtonom o’lchash va kommutatsiya qurilmasi ROSSMA® IIOT-AMS TILT COUNTER Ex (Og’ish hisoblagich)

The ROSSMA IIOT-AMS TILT COUNTER switch registers housing tilt at angles greater than 15 degrees and counts the tilts. The switch operates autonomously and provides wireless data transmission via LoRaWAN or NB-IoT networks.

Purpose

Designed for use with devices and mechanisms where it is necessary to monitor the presence of oscillation (tilt) of moving parts. Contains two sensitive elements for tilt registration.

The switch can be used at industrial facilities, housing and utilities infrastructure, and hard-to-reach locations (manholes, basements). The switch enables installation of measuring instruments in places without power sources and operates in harsh climatic and weather conditions.

Equipment is registered in the register of the Ministry of Industry and Trade of the Russian Federation as equipment manufactured on the territory of the Russian Federation (Conclusion 48859/11 dated June 11, 2021).

Operating Algorithm

Counting and accumulation of housing tilts is performed continuously. Packet transmission with counted data is performed via wireless network with period from 1 minute.

Recommendation: Do not set intervals less than 1 minute to ensure long autonomous operation.

Operating Modes

With delivery confirmation (Confirmed):

• Switch sends next packet only after receiving confirmation of previous delivery
• If confirmation not received after 3 retries, communication session ends
• Unsent data is saved to memory and transmitted in next session
• Advantage: guaranteed data delivery
• Disadvantage: increased power consumption

Without confirmation (Unconfirmed):

• Switch sends data at specified interval
• No packet delivery verification
• No unsent packets remain in memory
• Advantage: minimum power consumption
• Disadvantage: possible data loss

Transmission Period Configuration

Data transmission period is configured via wireless network commands:

• Default: once per 15 minutes
• Minimum: 1 minute (not recommended for long autonomous operation)
• Maximum: unlimited

Communication time management is performed via LoRaWAN network server and can be adjusted by command.

Indication

The ROSSMA IIOT-AMS TILT COUNTER switch has the following indicators:

• ACT – tilt registration (sensor triggered)
• LoRa – data transmission/reception via LoRaWAN network

The switch has a RESET button for device restart.
