Example 1
As shown in fig. 1, an embodiment of the present application provides a radar-based automatic monitoring method for a working fluid level of an oil well, where the method is applied to a radar intelligent monitoring and analysis system, and the system is communicatively connected to a first signal transmitting device and a first signal receiving device, and the method includes:
s100: obtaining a first position of the first signal transmitting device, and obtaining a first preset transmitting angle according to the first position;
specifically, in an actual oil well working fluid level monitoring process, the radar intelligent monitoring and analyzing system generally comprises a first signal transmitting device for transmitting electromagnetic wave signals and a first signal receiving device for receiving electromagnetic wave reflection signals. The electromagnetic wave signal emitted by the first signal emitting device contacts the liquid level in the oil well to emit, and is further received by the first signal receiving device, and then the liquid level in the oil well is measured according to the time between the emitting and receiving and the total height of the oil well.
The first signal transmitting device of the radar intelligent monitoring and analyzing system is generally arranged at a first position, close to the center, of the wellhead of the oil well, so that the problem that the liquid level in the oil well cannot be detected due to the fact that electromagnetic wave signals transmitted by the first signal transmitting device touch the inner wall of the oil well to transmit reflection or deflection in advance is avoided.
The first preset transmitting angle is generally set to be a transmitting angle perpendicular to the liquid level in the oil well, so that electromagnetic wave signals transmitted by the first signal transmitting device can be contacted with the liquid level in the oil well as perpendicularly as possible and reflected, further, the electromagnetic wave signals are prevented from contacting the inner wall of the oil well in the process of propagation or returning to the liquid level without a primary path in the process of reflection, the first signal receiving device cannot receive the reflected electromagnetic wave signals, and further, the problem that the liquid level in the oil well cannot be measured is avoided.

Therefore, it is necessary to make the first signal transmitting device transmit electromagnetic waves with different frequencies according to a certain frequency, make the frequency of the reflected electromagnetic wave received by the first signal receiving device different from the frequency of the electromagnetic wave transmitted by the first signal transmitting device at the same time, calculate the frequency difference between the two, and calculate the time of propagation and reflection of the electromagnetic wave in the oil well, so as to detect and obtain the height of the liquid level in the oil well.
In the embodiment of the present application, the first preset transmitting frequency is a frequency of the number of times of transmitting the electromagnetic wave by the first signal transmitting device in a predetermined period, and as described above, the frequencies of the electromagnetic wave itself transmitted in the predetermined period are different, so as to detect and obtain the liquid level height in the oil well.

The first signal transmitting device transmits electromagnetic waves according to a first preset transmitting frequency, so that the first electromagnetic wave signal set is theoretically also characterized by the first preset transmitting frequency.
