Descriptive Annex

1 INTRODUCTION

This pattern of an automatic catchweighing instrument, designated the Vehicle Data Hub (VDH), comprises one load cell, electronic equipment and position sensors mounted on a waste collection vehicle. This pattern automatically determines the weight of the loaded containers during the lifting process, then the weight of the empty containers on the way down to determine the net weight of refuse emptied. In addition, the container may be identified by an RFID tag reader system. The data is displayed on an indicator mounted near the operating console and recorded.

This pattern uses one load cell connected to a single weighing board. Two instruments (two load cells into two weighing boards) may be connected in a master-slave arrangement, allowing both weights to be added to obtain the total weight, for example for large trade containers. Two displays are used in this configuration, each display showing the individual net weight for the instrument (combined weights are recorded but not displayed). 2 FUNCTIONAL DESCRIPTION

2.1 Mechanical

Figures 1 shows a schematic representation of a typical installation configuration. 2.1.1 Load cell The pattern comprises one Flintec load cell type PC2H, maximum capacity 2000kg, mounted on the lifter at the rear of the vehicle (Figure 2). Its output is fed into an A/D converter and it is calibrated through the VDH Manager program. 2.1.2 Inclinometer The pattern comprises an inclinometer type LISD53E, mounted on the weighing board, to compensate for the pitch and roll of the vehicle. Its output is fed into the microcontroller and it is calibrated through the VDH Manager program. The maximum tilt angle shall not exceed 10%, weighing at greater angles shall be recorded as not legal for trade and an error code displayed.

2.1.3 Lift status and position sensing Analogue potentiometer(s) or proximity switches can be mounted on the lifter(s) connected to each VDH. These sensors can be fed to the VHD either through ADCs (for analogue signals) or into digital inputs (for digital signals). These sensors are used to determine status and position of the lifter(s). Alternatively the lifter(s) may communicate with the VDH through signal interfaces or buses, (for example CANBUS). The VDH monitors these signals and/or buses appropriately to determine lift status and position.

2.2 Electrical

2.2.1 VDH Unit

The unit operates from 17-32 V DC, supplied from the 24 V DC vehicle battery.

3/15

2.2.2 PCBs

The system comprises at least two PCBs; one Weighing PCB and the Back Plane PCB, which are appropriately enclosed and mounted in an IP66 aluminium box type AC200 (Figure 3). An example of mounting at the rear of the vehicle is shown in Figure 4. The system is supplied with 17 to 32V DC power, internal power supplies on the boards step the voltage to appropriate levels for the electronic components. A temperature sensor on the weighing boards compensates the weighing over the required temperature range.

2.2.3 CPU

The CPU on the weighing board is an ADSP 538 digital signal processor. The settings and calibrations for the VHD are stored on the memory on this board and read by the DSP. The memory also contains the weighing software. The VDH Manager Program is used to calibrate the board and store setup and calibration settings onto the weighing board memory.

2.2.4 Indicator

The proprietary display supplied with the system or any other CE-marked display may be used. On power-up the revision of the software is displayed. During operation the individual net weight including the measurement unit shall be clearly displayed and if appropriate the RFID tag number is displayed (Figure 5). Combined weights are not displayed.

2.2.5 On-board computer

The system is configured with an On-Board Computer (OBC). The OBC allows a screen in the cabin to facilitate sat-nav, customer address display etc.

2.2.6 RFID tag reader (optional)

Containers may be equipped with RFID tags that are read via an antenna located at the rear of the vehicle (Figure 6) before and after every weighing operation in order to allocate the weight of refuse emptied to a particular customer and charge accordingly for it. The optional RFID reader is built on the Weighing board, and its status is constantly monitored; when a tag is in view it is immediately read.

2.3 Devices

2.3.1 The instrument is not provided with any zero-setting or tare device due to its weighing principle. It is only used to calculate net weights by determining the difference between the two weights determined on the lifting and lowering cycles, hence any error due to a drift of zero does not affect the net result. 2.3.2 The VHD weighs dynamically, the parameters for the weighing window are protected and cannot be changed. 3 TECHNICAL DATA

3.1 The system has the following technical characteristics:

Individual container

Trade container

Max (kg) 300 600

3.2 Documentation and drawings The instrument is fully described in technical file held at NMO 3.3 Software 3.3.1 Operation The following sequence of events applies:

− Container is placed on lifting platform.

− Platform lifts container to be emptied.

− RFID tag information is read (when present).

− Lift position is monitored until optimum weighing position is reached.

− Weight is calculated and contents of container emptied.

− Weight of empty container measured on the down cycle.

− Net weight calculated and recorded

− Cycle complete 3.3.2 Weighing algorithms and adjustments Weighing is set to start automatically based on the lifter position. The weighing window cannot be modified by the user. The weight is adjusted for ambient temperature as measured by the onboard temperature sensor. The truck inclination is read and the final weight adjusted. 3.3.3 Start-up The display is tested at start-up, a pattern is written to the display to allow the user to verify that every pixel is functional. 3.3.4 Version number

The firmware identification is displayed on system start-up and is visible until the first lift is performed. The designation and version number shall be as follows:

VDH: V1.X.Y

with X and Y reflecting non-legally relevant changes to the software.

3.3.5 Security It is not possible to read or change the software code, and there is no provision for the end user to install new software or modify the weighing parameters.

A maintenance and calibration technician must use the "VDH Manager Program" to interface and/or update the legally relevant configuration and must use a password. There is no user interface access to the legally relevant data, parameters or software. The "VDH Manager

5/15

Program" is the only user interface available and only gives access to configuration settings. If changes are made to the legally relevant configuration, this causes a non-editable counter, designated “Configuration counter”, to increment. Its current value is shown on the display at start-up.

A checksum is included with the transmitted data as well as a known header and data structure information. Each measurement includes a time stamp, plus the unit’s VDH number and checksum. Data is stored on the OBC in the Alibi data storage device

If no communication is available from the weighing board then no weights are displayed nor recorded. 3.3.6 Data storage The following data shall be recorded for all measurements:

− Net weight with unit of measurement

− Instrument ID

− Date and time

− Firmware revision The data is stored on the Alibi Checker data storage device within the On-board computer located in the vehicle cabin. The data storage device is approved under Test Certificate GB-1225. 3.3.7 On-Board Computer The OBC does provide a touch screen interface for the vehicle driver screen but does not allow operation of the weighing system and as such is not subject to legal control. 4 PERIPHERAL DEVICES AND INTERFACES

7 ALTERNATIVES

7.1 Having a modified weighing algorithm and software structure.

7.1.1 The firmware is designated VDH: V2.X.Y, with X and Y reflecting non-legally relevant changes to the software. The security measures are as described in section 3.3.5.

7.1.2 The instrument may be fitted with a Data Storage Device within the weighing board itself, and replacing the storage device within the On-board computer described in section 3.3.6.

The following data is automatically recorded for all measurements:

− Gross weight (weight Up) with unit of measurement

− Tare weight (weight Down) with unit of measurement

− Net weight with unit of measurement

− Timestamp

− Instrument ID

− CRC check (corrupted records identified as such)

− Record ID (unique identification number for each measurement) Figure 8 shows an example of retrieved data.

7.1.3 The instrument may operate without the On-board computer described in section 3.3.6 when the integrated storage device described above is present. The instrument uses in this case the Masterboard located in slot 1, which manages the complete weighing operation. The instrument is self-contained, and the only user interface is the display indicator described in section 2.2.4.

In this configuration there is no requirement for an On-board computer, but one may be present.

7.2 Having a modified firmware designated VDH: V3.X.Y, with X and Y reflecting non-legally relevant changes to the software.

The firmware is as described in section 7.1 with the addition of a semi-automatic zero-setting device, with the following characteristics:

− Dynamic zero-setting, over the Up and Down parts of the cycle

− Range of zero-setting +/- 2% Max

− Accuracy of zero-setting ≤ 0.25 e The zero-setting is triggered by a push-button located by the display indicator. The zero-setting device requires two consecutive lifts to be within 0.25e of each other, in which case the first lift is taken as the new zero for the instrument. The zero-setting mode cannot be exited until this condition is achieved. The zero-setting device operates on individual weighers only; an interlock prevents the operation of the device for tilt angles exceeding 10%. 7.3 Instruments using the firmware described in section 7.2 may use the Up and Down weights as legal for trade (Gross and Tare weights, as opposed to Net weight only).

8/15

7.4 The instrument may be fitted with an AMCS SPL79-880kg (Emax = 880 kg) load cell instead of a Flintec PC2H (Emax = 2000 kg) load cell (see section 2.1.1). 7.5 Having a modified configuration comprising two load cells (on one lifter) connected to a single weighing board. The combined load cell signal is processed into the weight indication for the lifter by the weighing board.

This configuration may be used to weigh individual containers, with the specifications as listed in section 3.1.

This configuration may be also used to weigh individual or trade containers if the lifter is fitted with an extra wide chair. The specifications for both individual and trade containers in this case are: Max = 300 kg, e = 0.5 kg, Min = 2.5 kg.

The load cells may be either a pair of Flintec PC2H (Emax = 2000 kg) load cells or a pair of AMCS SPL79-880kg (Emax = 880 kg) load cells. 7.6 Having the instrument fitted with an Elite Transducers DT4650 load cell (Emax = 1000 kg), or a pair of DT4650 load cells in the configuration described in section 7.5.

7.7 Having modified software allowing the summation of left and right weight indications. The combined weight is indicated as Trade (Figure 9).

7.8 The instrument may be fitted with a Flintec PC5H (Emax = 2000 kg) load cell instead of a Flintec PC2H (Emax = 2000 kg) load cell (see section 2.1.1). 7.9 Having the instrument and lift installed on a fixed platform (e.g. waste compactor, Figure 10). 7.10 The zero-setting described in section 7.2 can also be triggered directly through the VDH Manager program. 8 ILLUSTRATIONS
