Claims

5 Air with a change in pressure from the chamber enters through the channel into the hot-wire anemometer 2, where a change in pressure leads to a change in the resistance of the thermistor. The signal from the output of the thermomemometer 2 through the electrical measuring circuit 3 is fed to the inputs of the pulse shaper 9, the element 10 for calculating the amount of motion and the element 11 for calculating the mass. Element 10 of calculating the amount of movement determines the amplitude value of the strain rate, which is a component of the amount of movement. The motion amount calculation element 10 is executed in the form of an extreme memory element, for example in the form of an electrical capacitance, sub-. connected through the diode to the source of the signal. The mass calculation element 11 determines the mass component. By integrating the magnitude of the strain rate over the time the wheel passes the magnitude of a section of the road, it is possible to obtain a component of the mass of the automobile. The mass calculation element 11 can be made in the form of an integrating chain and an operational amplifier. The signal from the output of the mass calculation element 1 and the signal from the output of the movement amount calculation element 10 are fed to the input of the speed calculation element 12. Signals from the outputs of the mass calculation element 11 and the speed calculation element 12 are fed to the shaper 13 and 16 of the code. A pulse from the output of the pulse driver 9 triggers the time sensor 6, the control element 18, the drivers 13 and 16 of the code. In this case, the formers 13 and 16 to convert single signals into the code. The sensor 6 of time produces a countdown of the time of passage of the first inter-center distance. Signals from outputs 19 and 20 of control element 18, information from shapers 13 and 16 of the code are transmitted through elements 14 and 17, element 15, to the input of calculating unit 5, where information is recorded on signal 21 from control element 18. When driving over the wheel sensor 1 of the second axis of the vehicle, the process of measuring the mass and speed is repeated. Additionally, at the output 22 of the control element 18, a signal is generated, which is fed to the second input of the time sensor 6. From the output of the latter, the time code through the element OR 15 enters the computational unit 5. The signal from the output 21 of the control element 18 in the computational unit 5 calculates the first center distance. Next, the computing unit 5 produces the summation of axial loads. According to the total axial load and the number of axles equal to two, the computing unit 5 selects, from the information input unit 7, a group of reference values for center distance for two-axis cars and compares the measured value for center distance with reference values. In case of equality with one of the reference values, the computing unit 5 determines the type of automobile, its own mass. Next, the computing unit determines the difference between the car's own weight and the measured total axial load corresponding to the weight of the transported cargo. After passing each axis of the vehicle through sensor 1 according to the signal from the output of sensor 6 of time, computing unit 5 calculates the maximum time over the allowable distance between vehicles at a given speed of movement. When driving over the sensor 1 of the wheels of the third axis of the vehicle, the computing unit stops calculating the maximum time. At its first input through the element OR 15, the elements AND 14 and 17, the shapers 13 and 16 of the code receive signals from the outputs of the mass calculation element 11 and the speed calculation element 12. Computing unit 5 begins to perform a sequence of operations, like sending the wheels of the second axle of a car. At the same time, on command from the output 21 of the control element 18, the computing unit 5 selects from the information input block 7 a set of axial spacings of three-axle vehicles, determines a new type of automobile, its mass, the mass of the truck. When driving over the sensor of the fourth axis of the vehicle, the computing unit 5, similarly to the above, determines its type, mass and the cargo being carried. After determining the maximum belt, the calculated parameters are calculated by the computing unit 5 to the registration unit 8. The use of the proposed device allows to obtain continuous 785 MO 3 during the day on various roads for various services relevant information, for example, dynamic loads on the road bed for the road condition monitoring service, traffic flow parameters, taking into account the type of vehicle, accounting of the transported cargo by type of vehicles for transport and production units, etc. In these cases, the device allows to significantly increase the production of TejtbHocTb labor of workers of these services.
