AUTOMATIC INDUSTRIAL STATION FOR VEHICULES TEAMS OF INTELLIGENT VALVES

Training

Module 2: operation types

Siemens Schrader (GB)

Each valve has:

An antennafor reception

+ An antenna for emission

Training

•

- Schrader (GB) (125 KHz / 315 MHz FM (FSK))- Siemens, Beru ( Allemagne) (125 KHz / 315 ou 433 MHz)- TRW ( USA) (125 KHz / 315 Mhz (ASK))- SMART TYRE (125 KHz / 433 MHz (ASK))- Toyota (Lexus) (125 KHz /315 MHz)- Pacific valve (Asie) - Johnson control (SAGEM)- etc………

Details on the valves available on the market:

After being awaked, the valve transmits its identifier and the pressure of the wheel. Each valve is programmable and can be sent to sleep again.

Example of information: Remaining lifespan of the battery, date of production of the valve, moisture, acceleration, Temperature....

Note: in general, to function the valve must be under pressure (> 500 mbar)

• Each valve has its own identifying code=> the driver knows which wheel is concerned

with a possible problem of under-inflation.

• This identifying code is also used to avoid an interference between 2 vehicles stationed one beside the other.

• Installed on the line of production, the station will transmit each code-identifier to the calculator of the vehicle, by the intermediary of the network machines.

Without that, the dashboard of the vehicle would indicate a "error", because no valve would be recognized by the calculator of the vehicle.

Training

• Frequency of activation: 125 KHz.

Range: adjustable of 20 cm at 60 cm maximum.

Cycle time : generaly 60 sec. *

Emission field: approximatively +/- 20 A/m (contact).

Reception AM/FM: 433 and/or 315 MHz (only one installation = bi-frequency)

Tape speed of the line of assembly: until 5m/min*

STATION TPMS:Technical data antenna / network

* depends on type of valve and line of assembly
