Page 6: Transmission Range And Function
Identification Systems HG 71451-A 1.4.2 Transmission Range and Function The field intensity of the magnetic alternating field decreases with an increasing dis- tance between transponders and reading antenna. Thus the information exchange is only feasible within a certain area. The field length L and the field width B of the transmission range (see Figure 2 auf Seite 6) will be defined via the parallel centre line through the reading antenna (road). -
Page 7: Signals And Timing
Identification Systems HG 71451-A 1.4.3 Signals and Timing With the transponders G 71310, G 71320 and G 71325. Signals and Timing Figure 3 Initially the data are insecure and the signal strength is still small (range II). Approach- ing further the signals of the data become stronger and can be read completely. The loss of the interception area is detected via the controller in that the thresholds are reached (3 and 4). -
Page 8: Components And Operation
HG 71370-W is able to change the positioning mode. The transponder code provides 16 Bit serially or parallel. 2.2 Identifying Antenna HG 71451-A (Profibus) The antenna system is in a 53 x 31 x 156.5 mm casing (polycarbonate). The antenna is connected by 5-pole cables. -
