Messenger
What can the Messenger save us time and money?
There are few reasons to implement an AVL, engine diagnostic or remote monitoring solution unless there are tangible benefits. The Messenger provides engine, vehicle and operator performance information to allow owners/operators to:
| Reduce downtime | Know when equipment needs maintenance before a breakdown occurs. Engine diagnostics provide a good start, and monitoring other engine parameters over time provides a more complete predictive view. The Messenger reports diagnostics as well as exceeded operating limits and max and min conditions. |
| Reduce fuel usage | By knowing exactly how much fuel is used idling and working, used at high speeds, used at high RPMS, you can define the "sweet spot" of operation and save fuel. |
| Increase operator efficiency | Capture speeding, hard braking, fast accelerations and poor MPG to confirm non-optimal operator performance. |
| Perform maintenance on your schedule | By precise reporting of engine hours, both idling and working, you can perform your maintenance on schedule.
Or use the engine load values and switch to maintenance based on accumulated engine load. |
| Go Green | By reducing the fuel usage you are reducing your carbon emissions - and have the data to prove it! |
| Increase equipment resale value | By maintaining equipment to a higher standard the value of your equipment is greater when you sell it. Provide a detailed record of all manintenance faults to justify your price. |
| Eliminate theft | Know where your equipment is at all times and when it moves out of your defined geofences. |
| Reduce wear and tear | By setting operating limits and know when they are being violated. |
| Create employee incentives | By knowing who follows company policies the best. |
| Better fleet and unit reporting | Allowing managers to quickly compare and detail individual pieces of equipment or entire fleets. Click here to see reports created from Messenger data. |
Overview
Each Messenger monitors and computes values from CANbus(J1939), OBD-CAN PGNs, J1708/1587 PIDs and 100s of Modbus RTU Registers When user-defined operating conditions are violated, like receipt of an engine diagnostic message, information is immediately sent to web-based partner applications.
The Messenger connects to the ECU through a single cable with a standard J1939, J1708 or OBD connector. Modbus Master communication is serial via RS-232 or RS-485. The dual GPS/GSM antenna connects to the two keyed connectors on the Messenger.
Communication to the internet-based applications is via UDP or TCP over a GSM, CDMA or Wi-Fi network. Various satellite communication options are also available.
How the Messenger Works
The Messenger continually monitors pre-defined values read from the engine, performs computations and limit comparisons on those values. These processed values are sent to an internet-based application based on a timed interval or when various conditions or limits violations occur.
The information sent to the internet includes the unit identification, GPS location, date/time, processed values based on PGN parameters of interest, computed values, remote unit status, etc.
Capabilities that provide real benefit
The Messenger is designed to provide a highly robust and configurable platform for unique applications. The powerful 32-bit processor, real-time operating system, FLASH and SRAM on the Messenger allow for:
- Virtual real-time transfer or monitored conditions
- Local computations and evaluations from monitored conditions
- User-specified PGNs to be monitored
- Event and data logging
- Exception-based reporting to internet-based applications
- Over-the-air tunneling into the Messenger or other OEM equipment attached to the Messenger for remote diagnostics or re-configuration
- Reprogram a single unit or 1000s of units automatically via FTP
- Automatic firmware upgrades via FTP
- Event log and current configuration upload via FTP
- SMS messaging to change configuration or request monitored values
- Notifications based on time, events or computations from data
- Very low power mode based on RPM limit or other conditions
- Over-the-air re-flashing of the Messenger application - add new capabilites to the Messenger without having to visit it!
