[0002] With the continuous development of wind resources, people's requirements for wind measurement technology are increasing. Pulse coherence Doppler wind measurement lidar is a commonly used detection equipment in the field of wind measurement. Pulse coherence Doppler wind measurement lidar uses Doppler coherence theory, that is, it achieves wind speed measurement by comparing the frequency shift of the transmitted laser pulse light signal and the reflected laser pulse light signal.

[0003] Nowadays, in order to measure wind conditions at a longer distance and achieve a higher range, it is necessary to continuously increase the width of the emitted laser pulse light signal. The larger the width, the larger the blind area. The blind area refers to the position close to the radar where the wind speed cannot be measured. The blind area is proportional to the width of the pulse.

[0004] However, in the prior art, the use of pulse coherent Doppler wind laser radar for wind speed measurement has the following problems: in order to solve the problems of high range and low blind area, higher requirements are placed on radar optical design, optical devices, mechanical design and mechanical parts. In addition to the increased design difficulty, the weight and volume of the radar increase, which also brings higher hardware costs; or the problems of high range and low blind area cannot be solved at the same time.

The method can be performed by a wind speed determination device, which can be implemented in the form of software and / or hardware, and optionally, by an electronic device, which can be a mobile terminal, a PC, or a server. Figure 1 As shown, the method includes:

[0021] S110. Determine a target parameter corresponding to at least one pulse width type based on distance values ​​of multiple altitude layers input by a user.

[0022] Among them, the distance value can be understood as the vertical distance from the radar to the corresponding position of a certain altitude layer, in meters. The altitude layer can be understood as the vertical distance interval covered by the radar signal, that is, the different levels or intervals detected by the radar in the vertical direction. In this embodiment, the number of altitude layers is not limited, for example, it can be 12 layers. In this embodiment, the distance value of each altitude layer is not limited, and the interval value between each altitude layer is also not limited. In this embodiment, the number of distance values ​​input by the user can be equal to the number of altitude layers.

[0023] Exemplarily, the number of altitude layers is 12. The distance values ​​of the 12 altitude layers may be respectively: 30, 40, 60, 80, 100, 140, 160, 180, 200, 220, 250, 300; or respectively: 30, 40, 60, 80, 100, 140, 180, 200, 260, 320, 350, 400; or respectively: 20, 25, 40, 80, 100, 140, 180, 200, 260, 320, 350, 400.

[0024] Among them, the pulse width type can be understood as a parameter. In this embodiment, there is no restriction on the pulse width type, for example, it can be 100ns, 200ns, 300ns, etc. In this embodiment, there is no restriction on the number of pulse width types, for example, it can be 3. In this embodiment, there is no restriction on the target parameter, which can be specifically configured according to the number of pulse width types and pulse width types.

[0025] The target parameters may include current parameters, pulse waveform parameters, pulse accumulation times, etc.

[0026] Among them, the current parameter can be used as a parameter basis for current switching. The pulse width type, pulse waveform parameter and pulse accumulation times can be used as a parameter basis for emitting laser pulse light signals.

[0027] In this embodiment, at least one corresponding pulse width type can be determined according to the distance values ​​of multiple altitude layers, and corresponding target parameters can be configured for each pulse width type. The target parameters can support dynamic modification.

[0028] Optionally, the target parameters corresponding to at least one pulse width type are determined based on the distance values ​​of multiple altitude layers input by the user, including: determining at least one target distance range based on the distance values ​​of the multiple altitude layers; determining at least one pulse width type based on the at least one target distance range; and configuring the target parameters corresponding to the at least one pulse width type.

[0029] In this embodiment, there is no limitation on the number of target distance ranges and specific distance ranges. Exemplarily, at least one target distance range includes at least one of the following: 20-30m, 30-300m, and 300-500m.

[0030] The at least one pulse width type includes at least one of the following pulse width types: a first pulse width type, a second pulse width type, and a third pulse width type.

[0031] The width of the first pulse width type is smaller than the width of the second pulse width type, and the width of the second pulse width type is smaller than the width of the third pulse width type.

[0032] Exemplarily, the first pulse width type may be 100 ns, the second pulse width type may be 200 ns, and the third pulse width type may be 300 ns.

[0033] Exemplarily, the target distance range of 20 to 30m corresponds to the first pulse width type, the target distance range of 30 to 300m corresponds to the second pulse width type, and the target distance range of 300 to 500m corresponds to the third pulse width type. The target parameters corresponding to each pulse width type are different or the same. For example, the current parameters corresponding to the three pulse width types can be 2500, 4000, and 5000, respectively. The pulse waveform parameters corresponding to the three pulse width types are also different, and the specific values ​​are determined according to the actual situation. The number of pulse accumulations corresponding to the three pulse width types can all be 10,000.

[0034] For example, when the distance values ​​of the multiple altitude layers are 30, 40, 60, 80, 100, 140, 160, 180, 200, 220, 250, and 300, respectively, the corresponding pulse width type is the second pulse width type, and there is only one type. At this time, the target parameter is fixed.

[0035] For example, when the distance values ​​of multiple height layers are 30, 40, 60, 80, 100, 140, 180, 200, 260, 320, 350, 400, respectively, two pulse width types are corresponding, namely the second pulse width type and the third pulse width type. At this time, the current parameters can be 4000mA and 5000mA respectively, and the current is switched once, the two different pulse waveform parameters, and the two pulse accumulation times can be 10000 or different.

[0036] For example, when the distance values ​​of multiple height layers are 20, 25, 40, 80, 100, 140, 180, 200, 260, 320, 350, and 400, respectively, there are three pulse width types, namely the first pulse width type, the second pulse width type, and the third pulse width type. At this time, the current parameters can be 2500mA, 4000mA, and 5000mA, respectively, and the current is switched twice, with three different pulse waveform parameters. The three pulse accumulation times can all be 7000, or they can be different.

[0037] In this embodiment, by determining the target distance range based on the distance values ​​of the multiple altitude layers, determining the pulse width type according to the target distance range, and configuring corresponding target parameters for the pulse width type, it is possible to automatically adjust the pulse width type, the number of pulse width types, and the target parameters corresponding to the pulse width type according to the distance values ​​of the multiple altitude layers, thereby satisfying the user's needs of increasing the measurement range while reducing blind spots.

[0038] S120. Within a set time period, emit a laser pulse light signal of at least one pulse width type based on the target parameter, and collect signal data reflected from corresponding positions at each altitude layer according to the at least one pulse width type.

[0039] The set duration can be 1s.

[0040] In this embodiment, at least one type of laser pulse light signal of pulse width can be emitted in sequence within a set time period according to target parameters corresponding to at least one type of pulse width, and signal data reflected from corresponding positions of each altitude layer can be collected according to the at least one pulse width type, and the signal data corresponding to at least one type of pulse width can be processed to obtain target signal data corresponding to each altitude layer, so that the wind speed value corresponding to each altitude layer can be obtained according to the target signal data corresponding to each altitude layer.

[0041] Exemplarily, at least one pulse width type is exemplified by the first pulse width type, the second pulse width type, and the third pulse width type. The emission and collection process may be: emitting a laser pulse light signal of the first pulse width type according to the target parameter corresponding to the first pulse width type, and collecting signal data reflected from the corresponding positions of each height layer. Emitting a laser pulse light signal of the second pulse width type according to the target parameter corresponding to the second pulse width type, and collecting signal data reflected from the corresponding positions of each height layer. Emitting a laser pulse light signal of the third pulse width type according to the target parameter corresponding to the third pulse width type, and collecting signal data reflected from the corresponding positions of each height layer.

[0042] Optionally, emitting a laser pulse light signal of at least one pulse width type based on the target parameters includes: switching to a set beam channel; emitting a laser pulse light signal according to the target parameters corresponding to the first pulse width type; and / or; emitting a laser pulse light signal according to the target parameters corresponding to the second pulse width type; and / or; emitting a laser pulse light signal according to the target parameters corresponding to the third pulse width type.

[0043] The setting of the beam channel can be understood as a specific direction or angle of emitting a laser pulse light signal. This direction or angle can be understood as the spatial directivity of the beam channel, which determines the detection direction of the radar.

[0044] In this embodiment, after the setting is switched to the setting beam channel, the parameters are initialized to obtain the initialization parameters. If the user inputs the distance values ​​of multiple height layers, the initialization parameters are replaced by the target parameters corresponding to at least one pulse width type determined according to the distance values ​​of the multiple height layers, and the target parameters are stored in the register. In this embodiment, when there is one pulse width type, the laser pulse light signal is emitted according to the target parameters corresponding to the pulse width type in the register, without switching the current; when there are multiple pulse width types, the laser pulse light signal is emitted in turn according to the target parameters corresponding to each pulse width type in the register and the necessary current switching is performed.

[0045] Exemplarily, at least one pulse width type takes the first pulse width type as an example. The laser pulse light signal is emitted according to the target parameter corresponding to the first pulse width type. Exemplarily, at least one pulse width type takes the second pulse width type as an example. The laser pulse light signal is emitted according to the target parameter corresponding to the second pulse width type. Exemplarily, at least one pulse width type takes the third pulse width type as an example. The laser pulse light signal is emitted according to the target parameter corresponding to the third pulse width type.

[0046] Exemplarily, at least one pulse width type has a first pulse width type and a second pulse width type. The laser pulse light signal is emitted according to the target parameter corresponding to the first pulse width type, and the current is switched, and the laser pulse light signal is emitted according to the target parameter corresponding to the second pulse width type.

[0047] Exemplarily, at least one pulse width type is a first pulse width type and a third pulse width type. The laser pulse light signal is emitted according to the target parameter corresponding to the first pulse width type, and the current is switched, and the laser pulse light signal is emitted according to the target parameter corresponding to the third pulse width type.

[0048] Exemplarily, at least one pulse width type is exemplified by the second pulse width type and the third pulse width type. The laser pulse light signal is emitted according to the target parameter corresponding to the second pulse width type, the current is switched, and the laser pulse light signal is emitted according to the target parameter corresponding to the third pulse width type.

[0049] Exemplarily, at least one pulse width type is exemplified by a first pulse width type, a second pulse width type, and a third pulse width type. According to the target parameter corresponding to the first pulse width type, the laser pulse light signal is emitted, the current is switched, and according to the target parameter corresponding to the second pulse width type, the laser pulse light signal is emitted, the current is switched, and according to the target parameter corresponding to the third pulse width type, the laser pulse light signal is emitted.

[0050] It should be noted that, taking 1s as an example, if the total number of laser pulses in 1s is 30,000, excluding the light-cutting time and the current switching time, there are about 22,000 remaining, then the sum of the accumulated pulse times of all pulse width types may not exceed 22,000.

[0051] In this embodiment, there is no restriction on the current switching time, which is in milliseconds.

[0052] In this embodiment, by switching to a set light beam channel and sequentially emitting laser pulse light signals of different pulse width types according to target parameters corresponding to different pulse width types, more accurate and flexible wind speed measurement can be achieved.

[0053] like Figure 2 As shown, Figure 2 A schematic timing diagram of emitting laser pulse light signals of various pulse width types provided in an embodiment of the present invention. Taking 1 second as an example, the set duration is used to complete a light cut (i.e., switch to the set beam channel) within 1 second, replace the initialization parameters with the target parameters, emit the laser pulse light signal according to the target parameters corresponding to the first pulse width type, switch the current, emit the laser pulse light signal according to the target parameters corresponding to the second pulse width type, switch the current, and emit the laser pulse light signal according to the target parameters corresponding to the third pulse width type.

[0054] S130. Determine the target signal data corresponding to each altitude layer according to the signal data corresponding to the at least one pulse width type.

[0055] In this embodiment, the signal data reflected from the corresponding position of each altitude layer corresponding to each pulse width type can be processed to obtain the spectrum results of each altitude layer corresponding to each pulse width type, determine the spectrum results corresponding to the target distance range corresponding to each pulse width type, and combine the spectrum results corresponding to the target distance range corresponding to each pulse width type into target signal data corresponding to each altitude layer.

[0056] Optionally, the target signal data corresponding to each altitude layer is determined based on the signal data corresponding to the at least one pulse width type, including: for each pulse width type, processing the signal data reflected from the corresponding position of each altitude layer to obtain the spectrum results of each altitude layer corresponding to each pulse width type; from the spectrum results of each altitude layer corresponding to each pulse width type, screening the spectrum results of at least one target altitude layer corresponding to each pulse width type; wherein the target altitude layer is determined according to the target distance range corresponding to the pulse width type; and combining the spectrum results of at least one target altitude layer corresponding to each pulse width type to obtain the target signal data corresponding to each altitude layer.

[0057] The number of all target altitude layers is equal to the number of the plurality of altitude layers. Exemplarily, if the number of the plurality of altitude layers is still 12, the number of target altitude layers is 12. The target signal data is the spectrum result of the target altitude layer.

[0058] In this embodiment, for each altitude layer of each pulse width type, spectrum calculation is performed on the signal data transmitted at the corresponding altitude layer position, and spectrum accumulation is performed as the spectrum result corresponding to the altitude layer, so that the spectrum results of each altitude layer corresponding to each pulse width type can be obtained.

[0059] Exemplarily, the distance values ​​of multiple altitude layers are 20, 25, 40, 80, 100, 140, 180, 200, 260, 320, 350, and 400, respectively, corresponding to three pulse width types, namely the first pulse width type, the second pulse width type, and the third pulse width type. The target distance range of 0 to 30m corresponds to the first pulse width type, the target distance range of 30 to 300m corresponds to the second pulse width type, and the target distance range of 300 to 500m corresponds to the third pulse width type. The target altitude layers corresponding to the first pulse width type are the first altitude layer and the second altitude layer, and the corresponding distance values ​​are 20 and 25 respectively; the target altitude layers corresponding to the second pulse width type are the third altitude layer, the fourth altitude layer, the fifth altitude layer, the sixth altitude layer, the seventh altitude layer, the eighth altitude layer and the ninth altitude layer, and the corresponding distance values ​​are 40, 80, 100, 140, 180, 200 and 260 respectively; the target altitude layers corresponding to the third pulse width type are the tenth altitude layer, the eleventh altitude layer and the twelfth altitude layer, and the corresponding distance values ​​are 320, 350 and 400 respectively.

[0060] Exemplarily, the spectral results of the first altitude layer and the spectral results of the second altitude layer corresponding to the first pulse width type, the spectral results of the third altitude layer, the spectral results of the fourth altitude layer, the spectral results of the fifth altitude layer, the spectral results of the sixth altitude layer, the spectral results of the seventh altitude layer, the spectral results of the eighth altitude layer and the spectral results of the ninth altitude layer corresponding to the second pulse width type, and the spectral results of the tenth altitude layer, the spectral results of the eleventh altitude layer and the twelfth altitude layer corresponding to the third pulse width type are combined as target signal data corresponding to each altitude layer.

[0061] In this embodiment, the signal data of different pulse width types are processed, the frequency spectrum results of at least one target altitude layer corresponding to each pulse width type are screened, and the frequency spectrum results of at least one target altitude layer corresponding to each pulse width type are combined, so that the target signal data of all altitude layers can be accurately obtained.

[0062] S140. Determine the wind speed value corresponding to each altitude layer based on the target signal data corresponding to each altitude layer.

[0063] In this embodiment, the wind speed value corresponding to each altitude layer can be accurately obtained through the target signal data corresponding to each altitude layer.

[0064] like Figure 3 As shown, Figure 3 A schematic flow chart of another method for determining wind speed provided in an embodiment of the present invention.

[0065] S301, switch to set beam channel.

[0066] S302: Are there target parameters? If yes, execute S303; if no, execute S304 directly according to the initialization parameters.

[0067] S303, write the target parameters into the register.

[0068] S304: Transmit a laser pulse light signal according to target parameters corresponding to the first pulse width type.

[0069] S305. Collect signal data reflected from corresponding positions at each altitude layer according to the first pulse width type.

[0070] S306. Process the signal data reflected from the corresponding position of each altitude layer to obtain the frequency spectrum results of each altitude layer corresponding to the first pulse width type.

[0071] S307 , emitting a laser pulse light signal according to target parameters corresponding to the second pulse width type.

[0072] S308. Collect signal data reflected from corresponding positions at each altitude layer according to the second pulse width type.

[0073] S309, processing the signal data reflected from the corresponding position of each altitude layer to obtain the spectrum results of each altitude layer corresponding to the second pulse width type.

[0074] S310 , emitting a laser pulse light signal according to target parameters corresponding to the third pulse width type.

[0075] S311. Collect signal data reflected from corresponding positions at each altitude layer according to the third pulse width type.

[0076] S312. Process the signal data reflected from the corresponding position of each altitude layer to obtain the spectrum results of each altitude layer corresponding to the third pulse width type.

[0077] S313. Filter the spectrum results of at least one target altitude layer corresponding to each pulse width type from the spectrum results of each altitude layer corresponding to each pulse width type.

[0078] S314, combining the frequency spectrum results of at least one target altitude layer corresponding to each pulse width type to obtain target signal data corresponding to each altitude layer.

[0079] The technical solution of the embodiment of the present application determines the target parameter corresponding to at least one pulse width type based on the distance values ​​of multiple altitude layers input by the user; within a set time length, based on the target parameter, emits the laser pulse light signal of the at least one pulse width type, and collects the signal data reflected from the corresponding position of each altitude layer according to the at least one pulse width type; determines the target signal data corresponding to each altitude layer according to the signal data corresponding to the at least one pulse width type; determines the wind speed value corresponding to each altitude layer based on the target signal data corresponding to each altitude layer. The embodiment of the present application determines the target parameter corresponding to at least one pulse width type according to the distance values ​​of multiple altitude layers, and emits the laser pulse light signal of at least one pulse width type according to the target parameter corresponding to the at least one pulse width type within a set time length, thereby ensuring that the wind speed of all altitude layers can be accurately measured within each set time length without increasing the hardware cost, and can solve the problems of high range and low blind area at the same time.

[0080] It should be noted that all processing processes in the above embodiments can use Field-Programmable Gate Array (FPGA) chips to strictly ensure synchronization and real-time performance, that is, each process cycle and the time of each pulse type are executed according to the configured target parameters. While emitting the laser pulse light signal of at least one pulse width type based on the target parameters, and collecting the signal data reflected from the corresponding positions of each altitude layer according to the at least one pulse width type, the target signal data corresponding to each altitude layer and the wind speed value corresponding to each altitude layer can be synchronously determined. The solution provided in this embodiment has good compatibility. It only needs to ensure that the total time of light cutting, that is, the total number of laser pulses within the set time length, remains unchanged, and the number of pulse accumulations of each pulse type can be adjusted arbitrarily.

[0081] It should be noted that different pulse width types require different current parameters, so the current needs to be changed in advance each time the pulse width type is switched. This process takes a certain amount of time. Using a circuit design with a higher response speed can effectively reduce this time.

[0082] The technical solution provided in this embodiment allows users to accurately obtain wind speed values ​​at all altitude levels by only inputting the distance values ​​of multiple altitude levels that need to be measured. For radar products, no other costs are added, and users do not need to perceive changes in pulse width types, but the measurement range is expanded and blind spots are reduced.

[0083] Figure 4 A schematic diagram of the structure of a wind speed determination device provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the device includes: a target parameter determination module 410, which is used to determine a target parameter corresponding to at least one pulse width type based on the distance values ​​of multiple altitude layers input by the user;

[0084] The emission collection module 420 is used to emit the laser pulse light signal of the at least one pulse width type based on the target parameter within a set time period, and collect the signal data reflected from the corresponding position of each altitude layer according to the at least one pulse width type;

[0085] A target signal data determination module 430 is used to determine the target signal data corresponding to each altitude layer according to the signal data corresponding to the at least one pulse width type;

[0086] The wind speed value determination module 440 is used to determine the wind speed value corresponding to each altitude layer based on the target signal data corresponding to each altitude layer.

[0087] The technical solution of the embodiment of the present application is to determine the target parameter corresponding to at least one pulse width type based on the distance values ​​of multiple altitude layers input by the user through the target parameter determination module; to transmit the laser pulse light signal of the at least one pulse width type based on the target parameter within the set time length through the emission collection module, and to collect the signal data reflected from the corresponding position of each altitude layer according to the at least one pulse width type; to determine the target signal data corresponding to each altitude layer according to the signal data corresponding to the at least one pulse width type through the target signal data determination module; to determine the wind speed value corresponding to each altitude layer based on the target signal data corresponding to each altitude layer through the wind speed value determination module.
