Abstract: 1,143,232. Train speed control. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. 18 March, 1966 [23 March, 1965; 14 Oct., 1965], Nos. 12162/65 and 43590/65. Heading B7N. [Also in Divisions G1 and G3] Apparatus for providing an indication of the speed of a train and for controlling the speed in accordance with a predetermined braking pattern comprises first and second cable loops 3 and 4, Fig. 3, arranged along the track in the pattern shown, loop 3 being connected to a signal source 5 operating at frequency fo and loop 4 being connected to the same source via a 90 degrees phase shift circuit 6 and a pick-up 1 on the train arranged to couple with the forward and return legs of each loop. Assuming the forward leg of loop 3 carries a reference (zero) phase signal, the forward leg of loop 4 and the return legs of loops 3 and 4 carry signals shifted in phase by 90, 180 and 270 degrees respectively and these signals when summed in the pick-up produce an output signal K cos 2 # (fo + V/#) t, where V is the train speed and the wavelength of the cable pattern. This signal when mixed with a signal at frequency fo, obtained on the train from a second pick-up 8 coupled to a loop 7 also arranged along the track, provides a signal having a frequency equal to V/# and where the pattern wavelength is constant, proportional to the speed of the train. By counting the number of cycles of this signal an indication of the distance travelled by the train is obtained. Speed control system.-Fig. 4. The signals from pick-ups 1 and 8 after amplification and filtering are mixed in unit 12 and the output signal having a frequency V/# is applied via L.P. filter 15 to a shaping circuit 16 feeding a counter 17. The counter is controlled to count input pulses for a period determined by a time base unit 18 and the count at the end of each period is applied via a digital-analogue converter to a comparator 20 in which it is compared with a fixed voltage from unit 21 representing a predetermined fixed number of pulses. The result of the comparison controls the train brake pressure via a control circuit 22. Thus the speed of the train is controlled to maintain the number of pulses per unit time or V/# constant and the train can be made to follow a particular braking pattern built into the track by altering successive wavelengths of the track loop pattern. Greater accuracy of control may be obtained, particularly at low speeds by increasing the frequency V/# by a factor N, Figs. 5 and 7 (not shown), and Fig. 8 (not shown) indicates an arrangement for deriving from the signal picked up an indication of the direction of travel. The signal source 5 may be provided on the train, Fig. 9 (not shown).
