AUTOMATIC INDUSTRIAL STATION FOR VEHICULES TEAMS OF INTELLIGENT VALVES Module 2: operation types
Siemens Schrader (GB) Each valve has: An antenna for reception + An antenna for emission
- 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)
Waiting time for detection of the vehicle PHASE 1
Detection of the balancelle and the Vehicle PHASE 2
Recovery of the identifier of the valve PHASE 8
Even proceeded with the back valves Back wheels
Sending of information to the network machines Results
Technical configuration VT520 Network machines x 1 control cabinet, 1 VT520, 2 antennas
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.
Frequency of activation: 125 KHz. l Range: adjustable of 20 cm at 60 cm maximum. l Cycle time : generaly 60 sec. * l Emission field: approximatively +/- 20 A/m (contact). l Reception AM/FM: 433 and/or 315 MHz (only one installation = bi-frequency) l 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
