DeLaval positioning module AFC_ASN General The positioning module AFC_SENS board is used for navigating an autonomous vehicle (HOST) along an inductive guidance wire embedded within concrete floor. AFC_SENS board integrates two functions: detection of the guidance wire – vehicle guiding function detection of FDX type RFID tags – coding of special action for vehicle along path Product overview Picture 1. Product overview Picture 2.
DeLaval positioning module AFC_ASN Block diagram Inductive line detection circuit The inductive line detection circuit consists of four sensors, each using two ferrite coils, which are detecting the magnetic field generated by the wire. The four separate sensors allows HOST to determine its transverse displacement in relation to the wire. RFID tag reader circuit The RFID reader uses two rectangular air coils (measuring 19.88”×8.
DeLaval positioning module AFC_ASN The tuning circuit on the receiving side ensures the receiving coil (RX coil) is always in resonance with the carrier frequency. The signal picked up by the RX coil is demodulated and then goes back to the microcontroller. Microcontroller AFC_SENS is based on NXP LPC4078 microcontroller (using 12 MHz crystal resonator), which performs several functions including: generation of the 133.
DeLaval positioning module AFC_ASN Data bytes 0-7 The byte 0 is used as a ‘Command byte’. The data bytes 1-7 are associated with parameters specific for given command. Commands 0x01 (Handing over identifier) Priority: 0x02 Direction bit: 0x00 (Slave -> Master) Expected response: None Description: Sent cyclically by each node. Cycle time for initialization status = 0 is about 30 seconds, for initialization status ! = 0 about 5 seconds. Can be used to detect new participants on the bus.
DeLaval positioning module AFC_ASN 0x01 (Requesting identier) Priority: 0x01 Direction bit: 0x01 (Master -> Slave) Expected response: 0x01 Description: Master can request Identify to check if all registered subscribers are on the bus. Every approx. 30 sec the cyclic transmission is reset.
DeLaval positioning module AFC_ASN 0x39 (AFC_Sens handover [responses]) Priority: 0x01 Direction bit: 0x00 (Slave -> Master) Expected response: none Description: Hands over requested data or confirms receiving CAN settings Data byte 0 1 2 ⁞ 7 Meaning AFC_Sens Mode DB 2 ⁞ DB 7 Data byte 1 (Mode) Value Meaning 0x00 Response with Status 0x01 Response with cycle time 0x02 Response with inductive line lateral position / tag ID 0x03 Alive response Value Comment 0x39 0x## Values presented in th
