Title: Means for detecting presence and movement of bodies
IPC: G08G1/01
Filed: 1945-10-05
Abstract: 615,978. Road signals for controlling traffic. AUTOMATIC SIGNAL CORPORATION. Oct. 5, 1945, No. 25971. Convention date, Oct. 7, 1944. [Class 118 (ii)] [Also in Group XL (c)] In a traffic control system, means are provided for determining the direction of travel of a vehicle in a predetermined traffic path. A wave director 17 (Fig. 1) situated at the control point directs a narrow beam 12 of frequency - modulated ultra - high - frequency radio waves along a road and the waves reflected by a vehicle such as 11 are received by 17 and heterodyned with the transmitted wave in the transceiver 16. After detection and amplification in an A.V.C. amplifier, the beat frequency is applied to frequency selective circuits arranged to operate appropriate speed, direction and distance, &c. indicating devices. Details of these circuits are shown in Fig. 2 and comprise inductively coupled coils 21, 22 tuned to the frequency band representative of the distance over which it is desired to establish a zone of detection, a power amplifying valve 26 and a resistor-capacitance network 34, 35, 36, 37 which with resistor 38 comprises a voltage divider, the ratio of which is proportional to frequency over a frequency range determined by the values of the condensers 35, 37. The voltage across resistor 38 which is proportional to the beat frequency and therefore to the distance of the reflecting vehicle from the control point, is rectified in valve 40, a voltmeter 43 calibrated in terms of distance being included in the output of the rectifier. To determine the speed of the vehicle, the voltage across resistor 41 is applied to a thermionic voltmeter 46, 47 through condenser 44, the impedance of which is directly proportional to the rate of change of this voltage and consequently to the speed of the vehicle. The. thermionic voltmeter has a centre zero corresponding to zero movement of the vehicle and deflection to one side or the other indicates both the speed and direction of the vehicle. To reduce the spurious peak reading on meter 47, as the vehicle enters or departs from the controlled zone, the output of valve 26, when it exceeds a predetermined value, is arranged to cause two locking valves 77, 78 to conduct and thus to short-circuit the input to valve 46. By means of a system of relays, Fig. 3 (not shown), information regarding the presence and motion of the vehicle in both the " approach " and " departure " direction, is indicated by either visual or audible signal apparatus. This information includes indications of parked vehicles, moving vehicles and speeds greater than or less than a predetermined speed. A modified Eccles-Jordan multi-vibrator circuit, Fig. 4 (not shown), arranged to trigger on the positive peaks of the beat frequency and supplying an output voltage which is a function of vehicle speed may replace the resistancecapacity network 34 ... 37.
