Technical Field

[0001] The present invention relates to the field of integrated circuits, and in particular to a control method for a wind profiler radar. Background Art

[0002] Wind profiler radar is a remote sensing device that detects high-altitude wind fields by emitting electromagnetic beams in different directions to high altitudes, receiving and processing the information returned by these electromagnetic beams due to the uneven vertical structure of the atmosphere. Wind profiler radar uses the Doppler effect to detect the changes in meteorological elements such as wind direction and wind speed above it with altitude, and has the advantages of high spatial and temporal resolution and high degree of automation.

[0003] In actual applications, the infrastructure conditions around the wind profiler installation site will affect the normal operation and use of the wind profiler.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The embodiment of the present application provides a control method for a wind profiler radar, which can realize power-on self-start of the wind profiler radar when the mains power is frequently cut off or the voltage is unstable, so as to improve the environmental adaptability of the wind profiler radar.

[0048] The control method of the wind profiler radar is applied to the incoming call self-starting control device of the wind profiler radar, see Figure 1The incoming call self-start control device of the wind profile radar mainly includes: an analog-to-digital conversion processing circuit 101, a first solid-state AC relay 102, a second solid-state AC relay 103, at least one AC sampling and shaping circuit 104, and a first switch circuit 105 with the same number of circuits as the AC sampling and shaping circuit 104.

[0049] Among them: the analog-to-digital conversion processing circuit 101, the AC sampling and shaping circuit 104 and the first switch circuit 105 are all arranged on the circuit board, the sampling end of the AC sampling and shaping circuit 104 receives the AC sampling signal corresponding to the AC sampling point, and the AC sampling signal is a voltage sampling signal representing that the incoming call self-starting control device receives the mains; the output end of the AC sampling and shaping circuit 104 is connected to the first input end of the analog-to-digital conversion processing circuit 101 and outputs the AC sampling and shaping signal.

[0050] The first output terminal of the analog-to-digital conversion processing circuit 101 is connected to the input terminal of the first switch circuit 105 and outputs a switch control signal. Specifically, the switch control signal is a signal that controls the first switch circuit 105 to be turned on or off.

[0051] The output end of the first switch circuit 105 is respectively connected to the control end of the first solid-state AC relay 102 and the control end of the second solid-state AC relay 103 to output a relay control signal. The first solid-state AC relay 102 is connected in series between the uninterruptible power supply output end of the wind profile radar and the AC power access end of the transmitter cabinet through its own input and output ends. The second solid-state AC relay 103 is connected in series between the uninterruptible power supply output end and the AC power access end of the receiving cabinet through its own input and output ends.

[0052] In practical applications, if the number of paths of the AC power shaping circuit 104 is set to 1, the AC power shaping circuit 104 will output one AC power sampling and shaping signal to the analog-to-digital conversion processing circuit 101, and the corresponding analog-to-digital conversion processing circuit 101 will output one switch control signal after performing analog-to-digital conversion processing on the AC power sampling and shaping signal; similarly, if the number of paths of the AC power shaping circuit 104 is 2, the analog-to-digital conversion processing circuit 101 will output two switch control signals, that is, the number of paths of the AC power sampling and shaping circuit 104 and the AC power sampling and shaping circuit 104 is the same, so that the analog-to-digital conversion processing circuit 101 can perform AC power detection at each sampling point and power on / off control under the corresponding detection results.

[0053] The control method of the wind profiler radar is as follows: Fig.15 As shown, the specific steps include:

[0054] S1501. Acquire an alternating current sampling signal of a wind profiler radar.

[0055] In practical applications, the AC sampling signal of the wind profiler radar can be obtained by starting the sampling and shaping circuit in the control device through the incoming call of the wind profiler radar.

[0056] The specific process of obtaining the AC sampling signal through the sampling and shaping circuit can be found in the above content and will not be repeated here.

[0057] S1502: Determine whether the voltage of the AC power received by the incoming call self-starting control device represented by the AC power sampling signal is within a normal range.

[0058] In actual applications, the voltage of the mains is not always stable, but will be affected by various factors and fluctuate. The power-on self-start control device should be started when the mains voltage is within the normal range, so as not to cause damage to the components in the wind profile radar system.

[0059] The normal range of voltage is the range of voltage required when the wind profile radar works normally. Specifically, the normal range can be 180V to 260V, but it is not limited thereto. Regardless of the value of the normal range, it belongs to the protection scope of this application.

[0060] If it is determined that the voltage of the incoming call self-starting control device received by the AC power represented by the AC sampling signal is within the normal range, step S1503 is executed; if it is determined that the voltage of the incoming call self-starting control device received by the AC power represented by the AC sampling signal is within the abnormal range, step S1504 is executed.

[0061] S1503, respectively connect the receiving cabinet and the transmitting cabinet to receive the mains power circuit.

[0062] In practical applications, the first solid-state AC relay and the second AC relay in the incoming power self-start control device of the wind profiler radar can be closed to connect the circuits of the receiving cabinet and the transmitting cabinet to receive the mains power respectively, so as to realize the self-start of the wind profiler radar.

[0063] S1504. Control the uninterruptible power supply in the wind profiler radar to supply power to the receiving cabinet and the transmitting cabinet.

[0064] In practical applications, by closing the first solid-state AC relay and the second AC relay in the incoming call self-starting control device of the wind profiler radar, the uninterruptible power supply in the wind profiler radar can be controlled to power the receiving cabinet and the transmitting cabinet through its internal battery, so as to realize the self-starting of the wind profiler radar.

[0065] See also Figure 1After the AC sampling and shaping circuit 104 obtains the AC sampling signal of the AC sampling point, it is processed by the analog-to-digital conversion processing circuit 101. When the analog-to-digital conversion processing circuit 101 determines that the AC sampling signal obtained by the AC sampling and shaping circuit 104 meets the startup requirements of the wind profiler radar, for example, the voltage of the mains is within the normal range (180V~260V), the transmitter cabinet and the receiver cabinet in the wind profiler radar are directly connected to the mains. Alternatively, if the voltage of the mains exceeds the normal range but the power of the uninterruptible power supply is sufficient, the battery inside the uninterruptible power supply is used to power it to maintain the normal operation of the wind profiler radar system. Specifically, in actual applications, when the acquired AC sampling signal meets the startup requirements of the wind profiler, the first switch circuit 105 can be controlled to be turned on according to the switch control signal output by the analog-to-digital conversion processing circuit 101, so that the first solid-state AC relay 102 and the second solid-state AC relay 103 are closed, and the circuit between the uninterruptible power supply and the transmitter cabinet and between the uninterruptible power supply and the receiver cabinet of the wind profiler radar is controlled to be turned on, and the transmitter cabinet and the receiver cabinet are powered by the AC power received by the uninterruptible power supply or the battery inside the uninterruptible power supply, so as to realize the self-starting of the wind profiler radar.

[0066] In practical applications, if the voltage of the mains is in an abnormal range, the uninterruptible power supply in the wind profiler radar can be controlled to supply power to the receiving cabinet and the transmitting cabinet through its internal battery. In addition, after the uninterruptible power supply supplies power to the receiving cabinet and the transmitting cabinet, it is determined in real time whether the current power of the uninterruptible power supply is lower than the power-off threshold according to the current power of the uninterruptible power supply, specifically the current power of its internal battery. If the current power of the uninterruptible power supply is lower than the power-off threshold, only the uninterruptible power supply is retained to supply power to the computer in the wind profiler radar, so that the limited power of the uninterruptible power supply can be provided to the computer, extending the working time of the computer, so that the remote operator has sufficient time to save radar data or perform other corresponding operations. Through the above description, it can be seen that the wind profiler radar can perform corresponding control operations according to the actual situation to realize the self-start of the wind profiler radar and ensure its normal operation, thereby improving the environmental adaptability of the wind profiler radar.

[0067] Based on the above principles, the present application can control the uninterruptible power supply in the wind profiler radar to power the receiving cabinet and the transmitting cabinet when the voltage of the AC power received by the incoming call self-starting control device represented by the AC sampling signal is not within the normal range, thereby realizing the self-start of the wind profiler radar, thereby reducing the impact of the AC power voltage fluctuation on each component in the wind profiler radar system and extending the working time of the wind profiler radar; it can also realize the self-start of the wind profiler radar by connecting the receiving cabinet and the transmitting cabinet to receive the AC power circuit when the voltage of the AC power received by the incoming call self-starting control device represented by the AC sampling signal is within the normal range, thereby ensuring the normal operation of the wind profiler radar and improving the environmental adaptability of the wind profiler radar.

[0068] Optionally, in practical applications, after executing step S1504 and controlling the uninterruptible power supply in the wind profile radar to supply power to the receiving cabinet and the transmitting cabinet, refer to Fig.16 , the control method further includes:

[0069] S1601. Determine whether the current power level of the uninterruptible power supply is lower than a power-off threshold.

[0070] The power-off threshold is a value corresponding to the power-off that should be executed when the power of the uninterruptible power supply is within a certain threshold range. Specifically, the value of the power-off threshold can be determined according to the parameters of the uninterruptible power supply or user needs, and this application does not make specific limitations, and all belong to the protection scope of this application.

[0071] If it is determined that the current power of the uninterruptible power supply is not lower than the power-off threshold, it means that the uninterruptible power supply can still guarantee the power supply to the wind profiler radar for a long time, does not affect the normal operation of the wind profiler radar, and does not need to be operated. If it is determined that the current power of the uninterruptible power supply is lower than the power-off threshold, step S1602 is executed.

[0072] S1602. Only the uninterruptible power supply is retained to supply power to the computer in the wind profiler radar.

[0073] In actual applications, when the power of the uninterruptible power supply is lower than a certain level, the power of the uninterruptible power supply can only sustain the working time of the wind profiler radar for a short time. At this time, the uninterruptible power supply to the transmitter cabinet and the receiver cabinet can be stopped, and only the power supply to the computer in the wind profiler radar is retained to extend the working time of the computer, so that the remote operator has sufficient time to save radar data or perform other operations.

[0074] However, in specific applications, the power supply of the uninterruptible power supply to each device can also be controlled according to manual control instructions issued by remote monitoring personnel.

[0075] It should be noted that, when the uninterruptible power supply has sufficient power, it can be used to power the transmitter cabinet and the receiver cabinet regardless of whether the mains voltage is within the normal range. However, in order to extend the working time of the wind profiler radar system and ensure the normal operation of the wind profiler radar, the backup power supply function of the uninterruptible power supply is generally only enabled when the mains voltage is not within the normal range, or the backup power supply function of the uninterruptible power supply is started after receiving the manual control command sent by the remote operator.

[0076] Optionally, in the incoming call self-starting device for executing the control method of the wind profile radar, see Figure 2 The AC sampling and shaping circuit includes: an overvoltage protection circuit 201, a first voltage transformation circuit 202, a voltage division processing circuit 203 and a first effective value detection circuit 204.

[0077] Among them, the first input end of the overvoltage protection circuit 201 receives the AC sampling signal AC1_L on the ignition line of the corresponding AC sampling point, the second input end of the overvoltage protection circuit 201 receives the AC sampling signal AC1_N on the neutral line of the AC sampling point, the first output end of the overvoltage protection circuit 201 is connected to the first input end of the first transformer circuit 202, and outputs the AC sampling signal on the corresponding live line, and the second output end of the overvoltage protection circuit 201 is connected to the second input end of the first transformer circuit 202, and outputs the AC sampling signal on the corresponding neutral line.

[0078] The output end of the first voltage transformer circuit 203 is connected to the input end of the voltage divider processing circuit 203 and outputs a first voltage transformer signal. The output end of the voltage divider processing circuit 203 is connected to the input end of the first effective value detection circuit 204 and outputs a voltage divider signal. The output end of the first effective value detection circuit 204 outputs a first detected effective value as the AC sampling and shaping signal.

[0079] In practical applications, the function of the overvoltage protection circuit 201 is to prevent the AC sampling signal received at the AC sampling point from having an excessive current, or from having an excessive current caused by an accident, which may damage the subsequent circuit.

[0080] The function of the first transformer circuit 202 is to output two sinusoidal wave signals with the same amplitude and a phase difference of 180° according to the input-output ratio of the AC sampling signal on the live line and the AC sampling signal on the neutral line, and to obtain a first transformer signal after rectifying the output signal, and output the first transformer signal to the voltage division processing circuit 203.

[0081] The voltage division processing circuit 203 is used to protect the safety of the subsequent circuit. It divides the first voltage conversion signal output by the first voltage conversion circuit 203 and sends the divided voltage signal to the input end of the first effective value detection circuit 204 according to a preset ratio.

[0082] The function of the first effective value detection circuit 204 is to process the voltage division signal through its own chip to obtain a DC signal equal to the effective value of the voltage division signal, that is, the AC sampling shaping signal. The DC signal is proportional to the effective value of the AC sampling signal on the AC sampling ignition line and the AC sampling signal on the neutral line.

[0083] It should be noted that Figure 2 The case of two AC sampling and shaping circuits is shown. However, in actual applications, the self-starting requirements of the wind profiler radar can also be achieved by using one AC sampling and shaping circuit. However, the more AC shaping circuits are used, the more AC sampling points there are. It is more reliable to achieve the self-starting of the wind profiler radar based on the AC sampling signals of more sampling points.

[0084] In practical applications, the power supply of wind profiler radar is generally that the AC power entering the radar cabin is first sent to the uninterruptible power supply, and the uninterruptible power supply is stabilized and then sent to the transmitter cabinet and the receiver cabinet. Therefore, if the following Figure 2 In the two-way AC sampling and shaping circuit shown, generally, one AC sampling point is set at the input end of the uninterruptible power supply, and the other sampling point is set at the output end of the uninterruptible power supply. Of course, the AC sampling point can also be set at other positions in the wind profiler radar depending on its application and user conditions. This application does not specifically limit the setting position of the AC sampling point. No matter where it is set in the wind profiler radar, it belongs to the protection scope of this application.

[0085] Since the composition and connection relationship of each AC sampling and shaping circuit are the same regardless of how many AC sampling and shaping circuits are used, for the convenience of description, the following description of the AC sampling and shaping circuit is based on the following description. Figure 2 The upper part shows an AC current sampling and shaping circuit as an example.

[0086] The overvoltage protection circuit 201 in the AC sampling and shaping circuit includes: a first resistor R30 and a first fuse F1.

[0087] Among them, one end of the first resistor R30 is connected to the AC sampling ignition line as the first input end of the overvoltage protection circuit 201, and receives the AC sampling signal AC1_L on the AC sampling ignition line. The other end of the first resistor R30 is used as the first output end of the overvoltage protection circuit 201, and outputs the AC sampling signal on the ignition line.

[0088] One end of the first fuse F1 is connected to the AC sampling point neutral line as the second input end of the overvoltage protection circuit 201 and receives the AC sampling signal AC1_N on the sampling point neutral line. The other end of the first fuse F1 is connected to the AC sampling signal on the neutral line as the second output end of the overvoltage protection circuit 201 and outputs the AC sampling signal on the neutral line.

[0089] Specifically, the resistance of the first resistor R30 is 200 ohms, and the parameter of the first fuse F1 is 0.5A.

[0090] The first voltage transformation circuit 202 in the AC sampling and shaping circuit includes: a first induction transformer T1, a first diode D1, a second diode D2 and a second resistor R33.

[0091] Among them, the same-name end of the primary winding of the first induction transformer T1 serves as the first input end of the first transformer circuit 202 to receive the AC sampling signal AC1_L on the live line, and the opposite-name end of the primary winding of the first induction transformer T1 serves as the second input end of the first transformer circuit 202 to receive the AC sampling signal AC1_N on the neutral line.

[0092] The same-name end of the secondary winding of the first induction transformer T1 is connected to the anode of the first diode D1, the opposite-name end of the secondary winding of the first induction transformer T1 is connected to the anode of the second diode D2, and the center point of the secondary winding of the first induction transformer T1 is grounded GND through the second resistor R33.

[0093] The cathode of the first diode D1 is connected to the cathode of the second diode D2, and the connection point serves as the output end of the first voltage transformation circuit T1 to output the first voltage transformation signal.

[0094] Specifically, the specific model of the first inductive transformer T1 may be Trans CT, and the specific models of the first diode D1 and the second diode D2 may be Diode 1N5404.

[0095] The voltage division processing circuit 203 in the AC sampling and shaping circuit includes: a third resistor R32, a fourth resistor R37 and a first capacitor C40.

[0096] Among them, one end of the third resistor R32 serves as the input end of the voltage divider processing circuit 203 and receives the first voltage-changing signal. The other end of the third resistor R32 is respectively connected to one end of the fourth resistor R37 and one end of the first capacitor C40. The other end of the fourth resistor R37 is grounded GND. The other end of the first capacitor C40 serves as the output end of the voltage divider processing circuit 203 and outputs the voltage divider signal.

[0097] Specifically, the resistance value of the third resistor R32 is 1M ohm, the resistance value of the fourth resistor R37 is 100K ohm, and the capacitance value of the first capacitor C40 is 0.1uf.

[0098] The first effective value detection circuit 204 in the AC sampling and shaping circuit includes: a first effective value detection chip U9, a fifth resistor R38, a sixth resistor R42, a second capacitor C39 and a third capacitor C41.

[0099] Among them, the IN1 pin 2 of the first effective value detection chip U9 serves as the input end of the first effective value detection circuit 204 and receives the voltage division signal. The IN2 pin 3 of the first effective value detection chip U9 is respectively connected to one end of the fifth resistor R38 and one end of the sixth resistor R42. The other end of the fifth resistor R38 receives the first power supply voltage P5V, and the other end of the sixth resistor R42 is grounded GND.

[0100] The GND pin 1 and the SD pin 8 of the first effective value detection chip U9 are respectively connected to the ground GND.

[0101] The Vp pin 7 of the first effective value detection chip U9 is connected to one end of the second capacitor C39, the connection point receives the first power supply voltage P5V, and the other end of the second capacitor C39 is grounded GND.

[0102] The VOUT_RIN pin 6 of the first effective value detection chip U9 is connected to one end of the third capacitor C41, and the connection point is grounded GND.

[0103] The VOUT pin 5 of the first effective value detection chip U9 is connected to the other end of the third capacitor C41, and the connection point serves as the output end of the first effective value detection chip U9, outputting the first detection effective value AC RMS OUT1 as the alternating current sampling and shaping signal.

[0104] In practical applications, the specific model of the first effective value detection chip U9 can be LTC1967, the resistance of the fifth resistor R38 is 20K ohms, the resistance of the sixth resistor R42 is 10K ohms, the capacitance of the second capacitor C39 is 0.1uf, and the capacitance of the third capacitor C41 is 10uf.

[0105] Also combined Figure 2 The specific working process of the AC sampling and shaping circuit is as follows: through the external interface P4 of the circuit board, the AC sampling signal AC1_L on the AC sampling ignition line and the AC sampling signal AC1_N on the neutral line are received. In order to prevent accidental excessive current, the AC sampling signal AC1_L on the live line is connected in series with the first resistor R30 with a resistance of 200K ohms, and the AC sampling signal AC1_N on the neutral line is connected in series with the first fuse F1 of 0.5A, and then connected to the input end of the first induction transformer T1. Among them, the first induction transformer T1 outputs two sine wave signals with the same amplitude and a phase difference of 180° with an input-output ratio of 220:8. After half-wave rectification by the first diode D1 and the second diode D2, they are converged to the third resistor R32. At this time, the signal waveform converged on the third resistor R32 is as follows: Figure 3As shown. In order to ensure the safety of the subsequent circuit, the signal output by the third resistor R32 is sent to the 1IN pin 2 of the first effective value detection chip U9 at a ratio of 1%; since the first effective value detection chip U9 and some auxiliary capacitors and resistors such as the fifth resistor R38, the sixth resistor R42, the second capacitor C39 and the third capacitor C41 constitute an effective value detection circuit with high accuracy, a DC signal AC RMSOUT1 equal to the effective value of the input signal of its 1IN pin 2 is obtained at the VOUT pin 5 of the first effective value detection chip U9.

[0135] In practical applications, the resistance of the seventeenth resistor R38 may be 200K ohms.

[0136] Also combined Figure 4The specific working process of the AC sampling and shaping circuit in the incoming call self-starting device of the wind profile radar is as follows: through the external interface P4 of the circuit board, the AC sampling signal AC1_L on the AC sampling ignition line and the AC sampling signal AC1_N on the neutral line are received. In order to prevent the accidental excessive current, the AC sampling signal AC1_L on the live line is connected in series with the first resistor R14 with a resistance of 200K ohms, and the AC sampling signal AC1_N on the neutral line is connected in series with the first fuse F2 of 0.5A, and then connected to the input end of the second induction transformer T2. The second induction transformer T2 will scale down the received signal and output two sine wave signals with an amplitude of 8V. One of the signals is sent to the shaping circuit 302 composed of the first shaping chip U2C and related resistors. The signal waveform after shaping by the shaping circuit 302 is a 50 Hz sine wave. Then, the shaped signal is sent to the second effective value detection circuit 303 composed of the second effective value detection chip U4 and related resistors and resistors to obtain the second detection effective value AC RMS OUT1. The second detection effective value AC RMS OUT1 is a DC signal. The second detection effective value AC RMS OUT1 is proportional to the signal of the AC sampling shaping circuit at the beginning. The other signal output by the second induction transformer T2 is also a sine wave proportional to the signal of the AC sampling shaping circuit at the beginning. Since it is connected to the first light-emitting diode LED0 and the seventeenth resistor R38 in the photoelectric intensity display circuit 304, it can quantitatively reflect the presence or absence of AC input and whether it is abnormal through the change of the light intensity of the first light-emitting diode LED0.

[0137] It should be noted that Figure 4 The AC sampling and shaping circuit shown needs to be powered by a +-15V dual power supply, which provides a +15V second power supply voltage P15V and a -15V third power supply voltage N15V to the AC sampling and shaping circuit respectively; Figure 2 The AC sampling and shaping circuit shown in the figure only needs to use a +5V first power supply voltage. Therefore, it can be seen that in practical applications, Figure 2 The AC sampling and shaping circuit solution provided in the corresponding embodiment is simpler.

[0138] Although the above shows the specific schemes of two AC sampling and shaping circuits, in actual applications, in addition to the two AC sampling and shaping circuit schemes shown above, other AC sampling and shaping circuits can also be used in the incoming call self-starting device that can execute the control method of the wind profiler radar. For example, a rectifier bridge can be used after voltage transformation, and then a large-capacity capacitor can be used for filtering and smoothing, and finally a DC voltage that can be detected can be obtained. Although the circuit of this scheme is simple, the DC voltage generated in the end fluctuates greatly, and because of the presence of large-capacity capacitors, the output DC voltage is insensitive to the input AC voltage; compared with this AC sampling and shaping circuit scheme, the wind profiler radar's incoming call self-starting device corresponding to the two AC sampling and shaping circuits provided above has higher safety, stability and accuracy, and can better ensure the stable and reliable execution of the control method of the wind profiler radar.

The capacitance value of the thirty-third capacitor C23 is 0.1uf. The specific model of the second low-noise power supply chip 4 is LT1763CS8-3.3.

[0162] It should also be noted that other conventional circuits in the analog-to-digital conversion processing circuit used in conjunction with the single-chip microcomputer chip U2 are no different from the prior art. For details, please refer to the relevant description of the prior art, which will not be repeated here.

[0163] In practical applications, see Figure 8 The first switch circuit includes: an eighteenth resistor R21, a nineteenth resistor R20, a tenth capacitor C24 and a first switch tube Q2.

[0164] Among them, one end of the eighteenth resistor R21 serves as the input end of the first switch circuit and receives the switch control signal, the other end of the eighteenth resistor R21 is respectively connected to one end of the tenth capacitor C24 and the control end of the first switch tube Q2, and the other end of the tenth capacitor C24 is connected to the source of the first switch tube Q2 and is grounded GND.

[0165] The drain of the first switch Q2 is connected to one end of the nineteenth resistor R20 , and the other end of the nineteenth resistor R20 serves as an output end of the first switch circuit and outputs the relay control signal AC1_AW.

[0167] Of course, in practical applications, the first switch tube Q2 may also be other types of transistors or triodes. Regardless of the type of switch tube the first switch tube Q2 is, it belongs to the protection scope of the present application.

[0168] Combination Figure 5 and Figure 8 The specific working process of the first switch circuit is: if the switch control signals output by the PC1 pin 9 of the single-chip microcomputer chip U2 in the analog-to-digital conversion processing circuit are all high level, the first switch Q2 is turned on and the relay control signal AC1_AW is output; otherwise, the first switch Q2 is not turned on.

[0169] It should be noted that Figure 8 Only one specific first switch circuit is shown, but in actual applications, the number of first switch circuits is generally the same as the number of AC sampling and shaping circuits. Since no matter how many first switch circuits are set, the specific composition and connection of each first switch circuit are the same, this application will not repeat the circuit setting of multiple first switch circuits, and no matter how many first switch circuits are specifically set, they all fall within the protection scope of this application.

[0170] In practical applications, since the number of paths of the first switch circuit is generally the same as the number of paths of the AC sampling and shaping circuit, if the number of paths of the AC sampling and shaping circuit is 2, the number of paths of the first switch circuit is also 2, such as Fig. 9As shown. When the number of paths of the AC sampling and shaping circuit and the first switch circuit are both set to 2, the AC sampling and shaping circuit outputs the AC sampling results of two sampling points to the analog-to-digital conversion processing circuit, that is, two shaping signals. The two shaping signals enter the single-chip microcomputer chip through their respective pins connected to the single-chip microcomputer chip in the analog-to-digital conversion processing circuit for analog-to-digital conversion processing, and output corresponding control signals at the pins connected to the corresponding first switch circuits in the single-chip microcomputer chip to control the on and off of the two first switch circuits respectively. In practical applications, since the single-chip microcomputer chip pins in the analog-to-digital conversion processing circuit are abundant, multiple signals can be simultaneously converted and output.

[0204] The first temperature sensor is installed in the receiving cabinet.

[0205] The second temperature sensor is installed on the surface of the preset temperature sensitive element.

[0206] See also Fig.11The specific working process of the first temperature sensor (not shown), the second temperature sensor (not shown), the first digital communication interface circuit 601, the second digital communication interface circuit 602, the follower circuit 603, the operation comparison circuit 604, the dual-channel DIP switch circuit 605, the preset temperature sensitive element temperature control circuit 606 and the third solid-state AC relay 607 is as follows:

[0207] The first digital communication interface circuit 601 is actually a circuit board J1, which is externally connected to two temperature sensors composed of LM135DZ, namely the first temperature sensor and the second temperature sensor. The first temperature sensor collects the temperature inside the receiving cabinet, and the second temperature sensor collects the temperature on the surface of the preset temperature sensitive element, and returns the collected temperature to the circuit board J1 from the 1st leg and the 10th leg of the circuit board J1 in the form of direct current.

[0208] At present, if the preset temperature sensitive element is a limiter, the first temperature sensor is suspended in the radar receiving cabinet, measures the radar ambient temperature, and returns the ambient temperature monitoring signal ANA_TEMP_LN_AMB; the second temperature sensor is installed close to the surface of the preset temperature sensitive element, measures the surface temperature of the preset temperature sensitive element, and returns the preset temperature sensitive element temperature monitoring signal ANA_TEMP_LN_LIMTER.

[0209] The two DC voltages pass through the magnetic beads to filter out some unnecessary burrs, and then are processed by the follower circuit 603 respectively, and output the follower ambient temperature monitoring signal TEMP_AMB and the follower preset temperature sensitive element temperature monitoring signal TEMP_LIMTER. The two signals are divided into two paths at the same time, one path goes to the single-chip microcomputer chip in the analog-to-digital analog-to-digital conversion processing circuit for digital signal processing, realizes digitization and makes corresponding processing, and the other path enters the operation comparison circuit 604. If the voltage amplitude of the follower preset temperature sensitive element temperature monitoring signal TEMP_LIMTER entering the operation comparison circuit 604 is 40mv higher than the voltage amplitude of the follower ambient temperature monitoring signal TEMP_AMB (that is, the temperature of the preset temperature sensitive element is 4°C higher than the ambient temperature), the operation comparison signal TEC_CTR2 output by the operation comparison circuit 604 is high, otherwise it is low.

[0210] The first input terminal of the dual-channel DIP switch circuit 605 inputs the operation comparison signal TEC_CTR2, and the other input terminal inputs the temperature control signal TEC_CTR1. The operation comparison signal TEC_CTR2 is a control signal generated by the analog circuit; the temperature control signal TEC_CTR1 is a control signal output by the single-chip microcomputer chip in the analog-to-digital conversion processing circuit after reading and processing the two signals, that is, the control signal generated by the digital circuit.

[0211] The dual-channel dial switch circuit 605 can select any one of the operation comparison signal TEC_CTR2 and the temperature control signal TEC_CTR1 according to the demand and output it to the preset temperature sensitive element temperature control circuit 606. The preset temperature sensitive element temperature control circuit 606 outputs a control signal again according to the signal received by itself to control whether the third solid-state AC relay 607 is turned on. Among them, when the preset temperature sensitive element temperature control circuit 606 controls the third solid-state AC relay 607 to be turned on, the external temperature control circuit can control the temperature of the preset temperature sensitive element; when the preset temperature sensitive element temperature control circuit 606 controls the third solid-state AC relay to be turned off, the external temperature control circuit stops controlling the temperature of the preset temperature sensitive element. Among them, the specific model of the third solid-state AC relay 607 is AQZ192; of course, in actual applications, the third solid-state AC relay 607 can also be other types of relays, and this application does not limit its specific type, which all belong to the protection scope of this application.

If the temperature information of the limiter or other preset temperature sensitive components in the wind profile radar is to be obtained, it can be obtained through the first temperature sensor and the second temperature sensor in the embodiment corresponding to FIG. 5 .

The specific model of the first remote control chip U7 is LT1763CS8-5.

[0264] Combination Fig.12 and Fig.13 , the specific working process of the air conditioner remote control start power circuit and the air conditioner remote control circuit is explained: the air conditioner start power circuit can be an infrared remote control circuit board, which is controlled by the single-chip microcomputer chip in the analog-to-digital conversion processing circuit. After the single-chip microcomputer chip automatically or remotely enables the air conditioner start power circuit, the air conditioner remote control start power supply outputs a 5V voltage source, that is, the air conditioner remote control start power circuit is started. After starting, the air conditioner remote control start power circuit can supply power to the air conditioner remote control circuit, so that the air conditioner remote control circuit automatically sends an infrared command to the air conditioner, sets the air conditioner to the preset working mode, and achieves the purpose of cooling the wind profile radar.

[0265] In practical applications, the air conditioner remote control circuit can also be controlled to automatically send infrared commands to the air conditioner at intervals to control the operation of the air conditioner.

[0266] The preset working mode can be a cooling mode, a dehumidification mode, and of course it can also be an adjustment of wind direction, wind speed, etc. This application does not make any specific limitations on the preset working mode, and all of them belong to the protection scope of this application.

[0267] Each time the analog-to-digital conversion processing circuit is powered on or receives a remote control command to turn on the air conditioner, the air conditioner remote control start power supply circuit is enabled to supply power to the air conditioner remote control circuit, so that it works for a preset time. Specifically, the preset time can be 60S or other values. This application does not specifically limit the value of the preset time, which belongs to the protection scope of this application.

[0268] Specifically, in practical applications, the air conditioner remote control circuit can be a control circuit in a HC-KT-01 module, and of course, can also be a control circuit in a YK003 infrared remote control module.

[0269] If it is the control circuit in the HC-KT-01 module, then Fig.13The air conditioner remote control circuit shown outputs a 5V voltage source, which enables it to automatically send a control signal to control the air conditioner to start up and work in the cooling mode at 24°C, so its control circuit is very simple.

[0270] If it is the control circuit in the YK003 infrared remote control module, it can achieve more flexible control of the air conditioner, such as switching from cooling mode to dehumidification mode, or adjusting the wind direction and wind speed, etc. However, if it is the control circuit in the YK003 infrared remote control module, it not only needs power supply, but also needs to obtain specific control instructions through the serial communication interface. Fig.13 After the air conditioner remote control circuit shown outputs a 5V voltage source to provide power, it also needs to pass Fig.10 The J2 interface 4, 5, and 9 legs in the provided fourth communication interface circuit can forward the air-conditioning operation instructions sent by the host computer to the digital-to-analog conversion module to the YK003 infrared remote control module. The YK003 infrared remote control module will issue corresponding instructions to the air-conditioning according to the instructions obtained to realize the corresponding functions, thereby further improving the environmental adaptability of the wind profiler radar.

[0271] Correspondingly, in actual applications, in the control method of the wind profiler, after executing step S1504 and controlling the uninterruptible power supply in the wind profiler radar to power the receiving cabinet and the transmitting cabinet, the control method also includes: controlling the air conditioner in the wind profiler radar to start and be in a preset working mode.

[0272] The specific process of controlling the air conditioner in the wind profile radar to start and be in a preset working mode may be any of the following:

[0273] (1) Automatic control The air conditioner in the wind profiler radar is started and in a preset working mode.

[0274] (2) Enable the air conditioner infrared remote control to control the air conditioner in the wind profile radar to start and be in the preset working mode.

[0275] (3) Receive and control the air conditioner in the wind profile radar to start and be in a preset working mode according to the control instructions issued by the host computer.

[0276] The preset working mode can be a cooling mode or a dehumidification mode, or it can be other working modes of the air conditioner. The present application does not specifically limit the preset working mode. As long as it belongs to the working mode of the air conditioner, it is within the protection scope of the present application.

[0277] In practical applications, after the air conditioner in the wind profile radar is started and in a preset working mode, the method further includes: receiving a remote control instruction from a host computer or a remote controller and controlling the air conditioner to enter a corresponding working mode.

[0278] Specifically, when the system where the wind profiler radar is located is powered on, the air conditioner can be started according to the preset working mode. After that, the air conditioner can be flexibly controlled by receiving remote control instructions from the host computer or remote control and controlling the air conditioner to enter the corresponding working mode through the control computer or remote control.

[0279] It should be noted that in practical applications, Fig.10 After the USART2 serial port provided by the fourth communication interface circuit 502 is connected, the state of the air conditioner can be flexibly set through the air conditioner remote control circuit.

[0280] On the basis of the above, see Fig.14 The wind profiler radar corresponding to the incoming call self-starting device that executes the above-mentioned wind profiler radar control method may specifically include: an uninterruptible power supply 1301, a receiving cabinet 1302, a transmitting cabinet 1303 and an incoming call self-starting control device 1304 of the wind profiler radar.
