DEVICE FOR VISUAL INDICATION OF THE ACCELERATION OR DECELERATION OF A TRANSPORT VEHICLE

摘要

The device is used in transport vehicles when the acceleration or deceleration exceeds the preset values. The visual indication is quick and accurate with comparable assessment of the critical values of the acceleration or deceleration of the movement with preset value allowances. The device includes an acceleration sensor (1) made of first integrated circuit (11) and a second integrated circuit performing the role of a amplifier (12) The output of sensor (1) is coupled to the input of a logical element consisting of a comparator unit (2), monovibrator (3) and pulse generator (4). The comparator unit (2) is made of two aperiodic links (21) of different time constants connected to the first and second input, respectively, of the integrated circuit (22). The monovibrator (3) is an awaiting multivibrator made of two logical elements AND-NO coupled to a differentiation link and a positive feed back. The output signal of the monovibrator (3) is coupled to the input of the pulse generator (4) the output of which is coupled to a control input of a unit for indication control (5) including the indication unit (6). All components are connected to the supply unit (7). 2 claims, 1 figure
