The Hägglunds CMp is a comprehensive system designed for condition monitoring of hydraulic drive systems, extending the capabilities of local hydraulic system control units. It collects and transmits data for remote condition monitoring, offering various connectivity options, sensor integration possibilities, and mounting alternatives.
Function Description
The core of the Hägglunds CMp system is the S-Link Monitoring Unit (SLMU), which houses the active components. The SLMU is a robust, stainless steel enclosure containing a CCM module (a small Linux computer), an optional MMM module (an interface for external sensors), and a GPRS router for data transmission via the mobile network. The system collects sensor data through a serial connection from the Hägglunds Spider 2 control system, utilizing existing sensors connected to the control unit and system internal signals for evaluation. Additional sensors can be integrated via one or more MMM I/O modules. The collected sensor data package is then transferred to the ODIN database via a GPRS router or Ethernet for calculation and evaluation of system behavior. Data transfer is encrypted using TLS/SSL over HTTPS Port 443 to ensure security.
The S-Link Hardware Package (SLHP) provides an overview of the monitored drive system, detailing the number of hydraulic motors (actuators), Drive Units (PEC, PAC, DUe, DUc), and additional sensors. The S-Link Mounting Package (SLMP) offers various assembly alternatives for the SLMU, allowing it to be mounted inside a PEC cabinet, on the side of a DU, or separately on a wall near the drive unit. The S-Link Sensor Package (SLSP) handles add-on sensors, including the sensor elements, adapter couplings for mechanical connection to the hydraulic system, and necessary connection cables.

Usage Features
The Hägglunds CMp system is designed for professional use in machine and system integration. It allows for flexible installation of the S-Link Monitoring Unit and various sensors to optimize condition monitoring. The system provides real-time data collection and transmission to the ODIN database for analysis and evaluation. Commissioning involves connecting the S-Link Monitoring Unit to the Spider control unit, installing antenna and power cables, and updating software and parameters using SpiderCom software. The system includes a drive log to store drive parameters over time, which may require reconfiguration after firmware updates. Start-up procedures involve verifying power indicators and communication between the S-Link Monitoring Unit and the Spider control unit.
