System Overview

System OverviewSystem Overview

System Overview

2.1 Overview

The entire purpose behind a fleet management system is to be able to remotely contact a vehicle, determine its location or status, and do something meaningful with that information. This could include displaying the vehicle location on a map, performing an address look-up, providing real-time driving directions, updating the vehicles ETA, monitoring vehicle and driver status or dispatching the vehicle to its next pick up.

These functions, of course, are completely dependent on the capabilities of the vehicle management application. The role of the CalAmp LMU-2x30™ is to deliver the location information when and where it is needed.

A typical fleet management system based on a CalAmp device includes the following components:

• A wireless data network

• An LMU-2x30™

• Host Device (GPS NMEA only)

• An LM Direct™ communications server

• Backend mapping and reporting software which typically includes mapping and fleet

reporting functions

• PULS™

• LMU Manager™

2.2 Component Descriptions

2.2.1 Wireless Data Network

The Wireless Data Network provides the information bridge between the LM Direct™ server and the LMU-2x30s™. Wireless data networks can take a variety of forms, such as cellular networks, satellite systems or local area networks. At this point in time, the networks available to the LMU-2x30™ are:

• GSM/GPRS

2.2.2 LMU-2x30™

The LMU-2x30™ is responsible for delivering the location and status information when and where it is needed. Data requests can come from any of the following sources:

• PEG™ script within the LMU-2x30™

• A location or status request from the LM Direct™ server

• A location or status request from LMU Manager

• An SMS request made from a mobile device such as a customer’s cell-phone

In some cases, it is necessary to run an application in the vehicle while it is being tracked by the backend software. Such examples could include instant messaging between vehicles or a central office, in-vehicle mapping or driving directions, email or database access. In most of these cases you will be using the LMU-2x30™ as a wireless modem as well as a vehiclelocation device.

2.2.3 LM Direct™ Server

LM Direct™ is a CalAmp proprietary message interface specification detailing the various messages and their contents the LMU-2x30™ is capable of sending and receiving. This interface allows System Integrators to communicate directly with LMU-2x30’s™. Please refer to the LM Direct™ Reference Guide for details.

2.2.4 Backend Software

Backend software is a customer provided software application. Regardless of its purpose, one of its primary functions is to parse and present data obtained from the LM Direct™ server. This allows the application to do any of the following:

• Display location database on reports received from the LMU-2x30™ in a variety of

formats

• Present historic information received from the LMU-2x30™, typically in a

report/chart style format

• Request location updates from one or more LMU-2x30s™

• Update and change the configuration of one or more LMU-2x30s™

2.3.2 GPRS (General Packet Radio Service)

“The General Packet Radio Service (GPRS) is a new non-voice value-added service that allows information to be sent and received across a GSM mobile telephone network. It supplements today's Circuit Switched Data and Short Message Service. GPRS is NOT related to GPS (the Global Positioning System), a similar acronym that is often used in

mobile contexts.”2

GPRS is being deployed in its initial stages in approximately 52 countries around the world. Keep in mind that GSM frequencies change depending on your geographic location. In Europe, GSM sits in both the 900Mhz and 1.8GHz bands. In North America it sits in the

1.9GHz and 850 MHz bands. This means, that in order to roam with your GSM/GPRS mobile between countries, it needs to be able to operate on multiple frequencies. The LMU2x30™ offers quad-band (850/900/1800/1900 MHz) capabilities to support networks worldwide.

Hardware Overview

3.1 Location Messaging Unit-2x30™ (LMU-2x30™)

3.1.1 LMU-2x30™ Handling Precautions

3.1.1.1 Electrostatic Discharge (ESD)

Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials caused by direct contact or induced by an electrostatic field. The term is usually used in the electronics and other industries to describe momentary unwanted currents that may cause damage to electronic equipment.

3.1.1.2 ESD Handling Precautions

ESD prevention is based on establishing an Electrostatic Protective Area (EPA). The EPA can be a small working station or a large manufacturing area. The main principle of an EPA is that there are no highly charging materials in the vicinity of ESD sensitive electronics, all conductive materials are grounded, workers are grounded, and charge build-up on ESD sensitive electronics is prevented. International standards are used to define typical EPA and can be obtained for example from International Electro-technical Commission (IEC) or American National Standards Institute (ANSI).

This ESD classification of the sub assembly will be defined for the most sensitive component, therefore the following classifications apply:

• Class 1B – Human Model (< 1 Kv)

• Class M1 – Machine Model (< 100V)

When handling the LMU-2x30’s™ main-board (i.e. sub assembly) by itself or in a partial housing proper ESD precautions should be taken. The handler should be in an ESD safe area and be properly grounded.

3.1.1.3 GPS Ceramic Patch Handling

When handling the sub assembly it may be natural to pick it up by sides and make contact with the antenna boards. In an uncontrolled ESD environment contact with the center pin of ceramic patch antenna can create a path for electrostatic discharge directly to the GPS Module. The GPS Module is very sensitive to ESD and can be damaged and rendered nonfunctional at low levels of ESD.

One should avoid contact with the center pin of the patch during handling. Going forward the Factory will be placing a protective layer of Kapton® tape over the patch element to eliminate this ESD path.

3.1.1.4 Packaging

Anytime the sub assembly is shipped and it is not fully packaged in its final housing it must be sealed in an ESD safe bag.

3.1.1.5 Electrical Over-Stress (EOS)

The GPS receiver can be damaged if exposed to an RF level that exceeds its maximum input rating. Such exposure can happen if a nearby source transmits an RF signal at sufficiently high level to cause damage.

3.1.1.6 Storage and Shipping

One potential source of EOS is proximity of one LMU-2x30™ GPS Antenna to another LMU-2x30™ GSM Antenna. Should one of the units be in a transmit mode the potential exists for the other unit to become damaged. Therefore any LMU-2x30™ GPS Antenna should be kept at least four inches apart from any active LMU-2x30™ GSM Antenna or any other active high power RF transmitter with power greater than 1 Watt.

3.1.2 Environmental Specifications

The LMU-2x30™ is designed to operate in environments typically encountered by fleet vehicles, including wide temperature extremes, voltage transients, and potential interference from other vehicle equipment.

To ensure proper operation in such an environment, the LMU-2x30™ was subjected to standard tests defined by the Society of Automotive Engineers (SAE). The specific tests included temperature, shock, vibration, and EMI/EMC. These tests were performed by independent labs and documented in a detailed test report. In accordance with Appendix A of SAE J1113 Part 1, the Unit is considered a “Functional Status Class B, Performance Region II” system that requires Threat Level 3 Testing.

The following shows the environmental conditions the LMU is designed to operate in and the relevant SAE tests that were performed. No formal altitude tests were conducted.
