Problems solved by technology

The photoelectric detection method is limited to transparent pipes. When the light cannot pass through the pipe, this method will not be used. At the same time, when the speed of the object is fast, the speed measurement is unstable; the passive inductive detection method, this method is due to the detection of passive detection method The distance is short, it is only suitable for the speed measurement of larger objects, but the speed of the smaller pipeline car will not be detected

Embodiment 1

[0033] Such as image 3 As shown, an instantaneous speed measurement system for pipeline vehicles based on the electromagnetic method, the measurement system includes an excitation coil located on the pipeline and a pair of detection coils installed on the pipeline vehicle, a core controller, an electromagnetic signal generating circuit, an electromagnetic signal receiving Conditioning circuit, wireless data transmission module and PC processing end; the electromagnetic signal generating circuit can have an alternating current with a constant effective value, so that the excitation coil generates a changing electromagnetic signal, and the detection coil receives the electromagnetic signal and transmits it to the electromagnetic signal Receive the conditioning circuit and transmit it to the core controller. The core controller calculates the instantaneous speed data of the pipeline car according to the time difference between the two received electromagnetic signals. The instant...

Embodiment 2

[0045] Concrete structure and application process are the same as embodiment 1.

[0046] A field test experiment was carried out by putting the pipe truck into the hydraulic conveying pipeline of the drum loading pipeline. The experimental pipe was a plexiglass round pipe with a total length of 44m and a pipe diameter of 100mm. There were devices for feeding and receiving pipe trucks at both ends of the pipe. During the experiment, the water is first pumped into the water delivery steel pipe by the centrifugal pump from the underground reservoir, the flow is adjusted by the valve, and then sent into the plexiglass pipe and the stainless steel pipe.

[0047] Use the electromagnetic method to measure 15 times at the same position of the pipeline at the same time, compare the results of the two measurements, and draw a graph such as Figure 5 As shown, the deviation value of the two is within 0.08m / s, the fluctuation of each point value in the measurement result is small, and the...

Abstract

The invention provides a pipeline vehicle instantaneous velocity measurement system based on an electromagnetic method. The system comprises an exciting coil located on the pipeline, and a pair of detection coils, a core controller, an electromagnetic signal production circuit, an electromagnetic signal receiving conditioning circuit, a wireless data transmission module and a PC processing end which are arranged on the pipeline vehicle; the electromagnetic signal production circuit can produce AC with an constant effective value, so that the exciting coil can produce changed electromagnetic signals; the detection coil receives the electromagnetic signals and transmits the electromagnetic signals to the conditioning circuit, and then transmits to the core controller; the core controller performs computation according to the time difference of receiving two electromagnetic signals so as to obtain the pipeline vehicle instantaneous velocity data; the pipeline vehicle instantaneous velocity data is transmitted to the PC processing end to store through a wireless data transmission module. The defect that the photoelectric method cannot measure the pipeline vehicle velocity in a non-transparent pipeline is solved, and the measurement system can be used as a mature pipeline vehicle instantaneous velocity measurement system to be popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of electromagnetism and pipeline hydraulic transportation, and in particular relates to an instantaneous speed measurement system of a pipeline vehicle based on an electromagnetic method. Background technique [0002] There are a series of problems restricting social development such as environmental pollution and consumption of large amounts of non-renewable energy in traditional railway and road transportation, air and water transportation. Therefore, seeking new energy-saving and environment-friendly transportation methods has become a key issue to be solved in the actual transportation industry. [0003] The hydraulic conveying method of the barrel-loading pipeline is an energy-saving and environment-friendly conveying technology in line with this concept. It uses water as the carrier, uses the pump as the power, and conveys materials through sealed pipes. The problem of energy consumption in the transp...
