Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of radar transmitters, and particularly relates to a high-frequency radar transmitting device and a transmitting control method thereof. BACKGROUND

[0002] The transmitter is an important component in a radar system, and mainly functions to amplify input signals and transmit the amplified signals to a transmitting antenna for radiation.

[0003] At present, the high-frequency radar transmitting device only has a single analog amplification function. When the antenna system environment of the transmitter changes, such as sudden power failure or parameter drift caused by strong wind, the transmitter will stop working. However, sometimes the antenna system environment of the transmitter changes only temporarily and does not need to be stopped for processing all the time. However, the high-frequency radar transmitting device stops working when the above-mentioned situation occurs, and needs to be manually checked and repaired before it can be started again, so the stability and continuity of the work are low. SUMMARY

[0004] Therefore, the application provides a high-frequency radar transmitting device and a control method thereof, which solve the problem of low stability and continuity of the high-frequency radar transmitting device.

[0005] The application adopts the following technical scheme:

[0006] The high-frequency radar transmitting device comprises a shell and a first transmitter installed in the shell.

[0007] The first transmitter is used to amplify input signals and transmit the amplified signals to an antenna for radiation.

[0008] The first transmitter is provided with an acquisition unit, a control unit and an execution unit.

[0009] The acquisition unit is used to acquire at least one parameter of the supply voltage, the bias voltage, the total current, the output voltage standing wave ratio and the temperature of the first transmitter, and input the acquired parameter to the control unit.

[0010] The control unit can compare the received parameter with a corresponding preset range. If the value of a certain parameter exceeds the corresponding preset range, the control unit sends a shutdown instruction to the execution unit.

[0011] The execution unit can shut down the first transmitter according to the received shutdown instruction, and send a restart instruction to the execution unit after a set time, and the execution unit restarts the first transmitter according to the received restart instruction.

[0012] Further, the execution unit in the first transmitter closes / restarts the first transmitter by cutting off / turning on the power supply or input signal of the first transmitting unit.

[0013] Further, the high-frequency radar transmitting device further comprises a display screen.

[0014] The display screen is signal-connected with the control unit in the first transmitter, and can display the values of the parameters collected by the collection unit in real time.

[0015] Further, the high-frequency radar transmitting device further comprises a second transmitter as a redundant backup.

[0016] The control units in the first transmitter and the second transmitter are signal-connected with an upper computer, and can upload the collected parameters to the upper computer and receive the control instructions issued by the upper computer.

[0017] Further, the high-frequency radar transmitting device further comprises a switch.

[0018] The output of the first transmitter is signal-connected with a first input channel of the switch, the output of the second transmitter is signal-connected with a second input channel of the switch, and the output channel of the switch is signal-connected with the antenna.

[0019] The control units of the first transmitter and the second transmitter can control the switch to switch the input channels, so as to realize the alternate work of the first transmitter and the second transmitter.

[0020] In addition, the application further provides a transmitting control method of the high-frequency radar transmitting device, comprising the following steps:

[0021] Step one: the first transmitter is started, the collection unit in the first transmitter collects at least one parameter of the power supply voltage, bias voltage, total current, output voltage standing wave ratio and temperature in the first transmitter, and inputs the collected parameter into the control unit of the first transmitter;

[0022] Step two: the control unit compares the input parameter with the corresponding preset range; if the value of a certain parameter exceeds the preset range, a closing instruction is sent to the execution unit, and the next step is entered; otherwise, step one is returned;

[0023] Step three: the execution unit automatically closes the first transmitter according to the received closing instruction, and the first transmitter starts the protection action;

[0024] Step four: after a set time A, the control unit sends a restarting instruction to the execution unit;

[0025] Step five: the execution unit makes the first transmitter restart according to the received restart instruction.

[0026] Further, after the step five, if there is an abnormal parameter whose value is beyond the preset range, the first transmitter is closed, and then step six is performed:

[0027] The control unit in the first transmitter adjusts the preset range of the abnormal parameter, so that the adjusted range can cover the value of the abnormal parameter, and after a preset time B, the adjusted range is restored to the corresponding preset range.

[0028] Further, after the step six, if there is an abnormal parameter whose value is beyond the corresponding preset range, the first transmitter is closed, and then step seven is performed:

[0029] The control unit in the first transmitter adjusts the preset range of the abnormal parameter, so that the adjusted range can cover the value of the abnormal parameter.

[0030] Further, if there is an abnormal parameter whose value is beyond the adjusted range, the first transmitter is closed, and then step eight is performed:

[0031] The control unit in the first transmitter shields the abnormal parameter, so that the abnormal parameter does not close the first transmitter, and makes the first transmitter work in the following mode: work for C1 minutes, stop working for P1 minutes, stop working for P1 minutes, work for C2 minutes, stop working for P2 minutes, and work for C3 minutes after stopping working for P2 minutes.

[0032] The C1, C2 and C3 increase in turn.

[0033] Further, if the value of a certain parameter in the parameters exceeds the preset bearing value of the first transmitter, the first transmitter is closed and switched to the second transmitter.

[0034] Advantages:

[0035] (1) The execution unit can close / restart the first transmitter according to the control instruction, and restart the first transmitter after a set time, which has high automation degree and ensures the stability and continuity of the work of the high-frequency radar transmitting device.

[0036] (2) The execution unit in the first transmitter can make the first transmitter close by cutting off the power supply voltage or input signal of the first transmitting unit, so that the work of the high-frequency radar transmitting device is more safe and reliable.

[0037] (3) The display screen is signal connected with the control unit in the first transmitter, and can display the parameter values collected by the collection unit in real time, which makes the working state of the transmitter be known in time and conveniently on the high-frequency radar transmitting device, and enhances the reliability of the working of the high-frequency radar transmitting device.

[0038] (4) The high-frequency radar transmitting device is also provided with a second transmitter, which is used as a redundant backup, enhances the continuous working ability of the high-frequency radar transmitting device, and further improves the stability and reliability of the high-frequency radar transmitting device.

[0039] (5) After the first transmitter is restarted for a set time A, if there is still an abnormal parameter in the collected parameters, i.e. the parameter is greater than the corresponding preset range, the restarted first transmitter will start the protection action again, and the first transmitter will be turned off. At this time, the control unit in the first transmitter will adjust the preset range of the abnormal parameter, so that the adjusted range can cover the value of the abnormal parameter, and after a set time B, the enlarged range will be restored to the original corresponding preset range. In this way, when the high-frequency radar transmitting device encounters a persistent fault in the periphery, such as a typhoon, the high-frequency radar transmitting device can continue to work by temporarily adjusting the preset range of the abnormal parameter, and the stability and continuity of the working of the high-frequency radar transmitting device are ensured.

[0040] (6) If the first transmitter starts the protection action after the enlarged range is restored to the original corresponding preset range, it means that it is not caused by temporary fault and persistent fault in the periphery, i.e. it is not caused by the change of the periphery environment, but it may be caused by the aging of the electronic components inside the first transmitter. At this time, the control unit adjusts the range of the abnormal parameter again, so that the adjusted range can cover the value of the abnormal parameter. In this way, when the electronic components inside the first transmitter are aging but the first transmitter can still work, the high-frequency radar transmitting device can continue to work, and the stability and continuity of the working of the high-frequency radar transmitting device are ensured.

[0044] The present application will be described in detail below with reference to the accompanying drawings and examples.​

[0045] Embodiment one:

[0046] With reference to Figure 1 With Figure 2 The embodiment provides a high-frequency radar transmitting device, which comprises a shell 5 and a first transmitter 1 installed in the shell, and wherein:

[0047] The first transmitter 1 is used for amplifying an input signal and transmitting the amplified signal to an antenna for radiation. Moreover, the first transmitter 1 is provided with a collection unit, a control unit and an execution unit, the collection unit is used for collecting at least one of a power supply voltage, a bias voltage, a total current, an output voltage standing wave ratio and a temperature of the first transmitter 1, wherein the temperature is a highest temperature collected by each temperature sensor arranged in the first transmitter 1 in the collection unit; the control unit is capable of comparing the collected parameters with corresponding preset ranges, if a value of a certain parameter exceeds the corresponding preset range, the control unit sends a shutdown instruction to the execution unit, the execution unit is capable of shutting down the first transmitter according to the received shutdown instruction, and the execution unit is capable of sending a restart instruction to the execution unit after a set time length, and the execution unit restarts the first transmitter 1 according to the received restart instruction.

[0048] The high-frequency radar transmitting device is further provided with a display screen 4, the display screen 41 is signal-connected with the control unit in the first transmitter, and the value of the parameter collected by the collection unit of the first transmitter 1 can be displayed in real time, so that the working state of the high-frequency radar transmitting device can be learned in time and conveniently, and the reliability of the working of the high-frequency radar transmitting device is enhanced.

[0049] Moreover, the shell of the high-frequency radar transmitting device is further provided with a second transmitter 2 as a redundant backup, the control unit in the second transmitter 2 is signal-connected with the display screen 4. The high-frequency radar transmitting device is provided with a switch 3, the outputs of the first transmitter 1 and the second transmitter 2 are respectively input into a first input channel and a second input channel of the switch 3, and then the switch 3 is signal-connected with the antenna through an output channel of the switch 3. The switch 3 is controlled to switch the first input channel and the second input channel by a voltage control circuit through a PIN tube, the control units of the first transmitter 1 and the second transmitter 2 can control the switch 3 to switch from the first input channel to the second input channel or from the second input channel to the first input channel through the voltage control circuit, so as to realize the alternate working of the first transmitter 1 and the second transmitter 2. The setting of the redundant backup second transmitter 2 enhances the continuous working capability of the high-frequency radar transmitting device.

[0050] In addition, if the input signals of the first transmitter 1 and the second transmitter 2 are from the receiver (the input signals are not echo signals received by the receiver), the control units in the first transmitter 1 and the second transmitter 2 can also turn off / on the receiver. Moreover, a switch for controlling signal input is arranged on the input signal line of the first transmitter 1 and the second transmitter 2, and the control units in the first transmitter 1 and the second transmitter 2 can turn off / on the switch. In this way, the first transmitter 1 and the second transmitter 2 can be turned off / on as required.

[0051] When the second transmitter 2 stops working, the transmitter can be stopped by cutting off the power supply voltage and the bias voltage, or by turning off the receiver or the switch, which makes the high-frequency radar transmitting device work more safely and reliably.

[0052] Moreover, the control units in the first transmitter 1 and the second transmitter 2 of the high-frequency radar transmitting device are connected with the host computer signal, can upload the collected parameters to the host computer in real time, and can also receive the control instructions issued by the host computer, which is beneficial to timely and remotely master the working state of the high-frequency radar transmitting device, and is also convenient for targeted maintenance work of the high-frequency radar transmitting device.

[0053] Embodiment Two:

[0054] On the basis of the above-mentioned embodiment one, the embodiment provides a transmitting control method of the high-frequency radar transmitting device, which comprises the following steps:

[0055] Step One: The first transmitter 1 is started, and the data acquisition unit in the first transmitter 1 collects at least one parameter of the power supply voltage, the bias voltage, the total current, the output voltage standing wave ratio and the temperature in the first transmitter 1, and inputs the collected parameters to the control unit in the first transmitter;

[0056] Step Two: The control unit compares the input parameters with the preset range corresponding to the parameters, and if the value of a certain parameter exceeds the corresponding preset range (which can be greater than or less than), sends a shutdown instruction to the execution unit, and enters the next step; otherwise, returns to Step One;

[0057] Step Three: The execution unit turns off the first transmitter 1 according to the received shutdown instruction;

[0058] Step Four: After a set time A, the control unit sends a restart instruction to the execution unit;

[0059] Step Five: The execution unit restarts the first transmitter 1 according to the received restart instruction.

[0060] Specifically, when any parameter such as the supply voltage, the bias voltage, the total current, the output voltage standing wave ratio, the temperature, etc. exceeds the preset range, the control unit sends a shutdown instruction to the execution unit, and the execution unit, after receiving the shutdown instruction, can shut down the first transmitter 1 by cutting off the supply voltage and the bias voltage of the first transmitter 1 or by other means such as closing the switch or closing the input signal of the receiver, i.e., the first transmitter 1 can start the protection action and automatically shut down when the parameter exceeds the preset range.

[0061] The control unit sends a restart instruction to the execution unit after a set time A (the set time A is relatively short, such as 1-3 hours), and the execution unit restarts the closed first transmitter 1 after receiving the restart instruction. In this way, the high-frequency radar transmitting device can automatically cut off the supply voltage and the bias voltage of the first transmitter 1 for protection in the case of temporary peripheral failure such as temporary strong wind or temporary power failure, which is called failure mode Y1, and can restart the closed first transmitter 1 after the set time A, so that the high-frequency radar transmitting device can recover to the normal working state after the temporary failure is removed. The high-frequency radar transmitting device is automatically shut down and restarted, with high automation degree, ensuring the stability and continuity of the operation of the transmitting device.

[0062] As an improvement, after the first transmitter 1 is shut down and restarted after the set time A, if the value of any parameter such as the supply voltage, the bias voltage, the total current, the output voltage standing wave ratio, the temperature, etc. still exceeds the preset range, i.e., there is an abnormal parameter, so that the restarted first transmitter 1 starts the protection action again and shuts down, the control unit in the first transmitter 1 adjusts the preset range corresponding to the abnormal parameter, so that the adjusted range can cover the value of the abnormal parameter, so that the first transmitter can continue to work, and after a set time B, the adjusted range is restored to the corresponding preset range (or restored to be close to the corresponding preset range). The set time B is relatively long, such as 24 hours, and it is considered that the continuous failure has been removed after the set time B. In this way, the high-frequency radar transmitting device can continue to work by temporarily adjusting the preset range of the abnormal parameter in the case of continuous peripheral failure such as typhoon, which is called failure mode Y2, ensuring the stability and continuity of the operation of the high-frequency radar transmitting device.

[0063] If the first transmitter 1 starts the protection action after the enlarged range is restored to the corresponding preset range after the set time B, it indicates that it is not caused by the temporary failure of the periphery and the persistent failure of the periphery, that is, it is not caused by the change of the peripheral environment, but it may be caused by the aging of the electronic components inside the first transmitter 1. At this time, the control unit adjusts the range of the abnormal parameter again, so that the adjusted range can cover the value of the abnormal parameter, without restoring to the preset range. In this way, in the case that the electronic components inside the first transmitter 1 are aging, but the first transmitter 1 can still work, a failure mode Y3 is called, so that the high-frequency radar transmitting device continues to work, and the stability and continuity of the work of the high-frequency radar transmitting device are ensured.

[0064] If the first transmitter 1 still starts the protection action after the above operation, it indicates that the electronic components inside the first transmitter 1 are damaged, which is called a failure mode Y4. At this time, the control unit shields the abnormal parameter, that is, the abnormal parameter does not make the first transmitter 1 start the protection action, and starts a test working mode: the control unit makes the first transmitter 1 work intermittently, for example: after shielding the abnormal parameter, the first transmitter 1 continues to work for a preset time C1 (such as ten minutes), during the C1 time, the abnormal parameter such as the total current will increase, but it does not exceed the preset bearing value of the first transmitter 1 (the bearing value can be obtained by test, or can be determined according to the specification of the electronic components inside the first transmitter such as the control chip), then after the first transmitter 1 works for C1, the control unit makes the first transmitter 1 stop working, and after stopping for a preset time P1, the first transmitter 1 works for a longer preset time C2 (such as twenty minutes), during the C2 time, if the total current still does not exceed the maximum total current that the first transmitter 1 can bear, then after the first transmitter 1 works for C2, the control unit makes the first transmitter 1 stop working, and after stopping for a preset time P2, the high-frequency radar transmitting device works for a longer preset time C3 (such as thirty minutes), during the C3 time, the total current is continuously monitored whether it exceeds the maximum total current that the first transmitter 1 can bear.

[0065] If the abnormal parameter does not exceed the preset bearing value of the first transmitter 1 during intermittent work, the test is passed, and the control unit makes the first transmitter 1 work continuously. Otherwise, the test is failed, the control unit turns off the first transmitter 1, and the upper computer starts the backup second transmitter 2, and the working mode of the second transmitter 2 is the same as that of the first transmitter 1.

[0066] The preset time length C1, the preset time length C2 and the preset time length C3 gradually increase, so that the situation that the first transmitter 1 is continuously worked, the first transmitter 1 is damaged (for example, the temperature is continuously increased, and the first transmitter is burned out), and the safety performance of the first transmitter 1 is improved. Moreover, through the test working mode, the first transmitter 1 has an opportunity (in the case of test passing) to continue to work continuously under the fault mode Y4, and the stability of the high-frequency radar transmitting device is ensured. The preset time length C1, the preset time length C2 and the preset time length C3 make the first transmitter 1 work intermittently, and the number of preset time lengths for making the first transmitter 1 work intermittently can be flexibly set according to the working condition.

[0067] It is worth noting that if the value of the parameter collected by the collection unit exceeds the preset bearing value of the first transmitter 1 or the temperature is sharply increased, the control unit directly controls the execution unit to close the first transmitter 1, the first transmitter 1 waits for repair, and the upper computer controls the second transmitter 2 to start. Moreover, the first transmitter 1 and the second transmitter 2 will upload the fault codes corresponding to the fault mode Y1, the fault mode Y2, the fault mode Y3 and the fault mode Y4 to the upper computer, so as to facilitate the subsequent repair of the transmitting device.

[0068] In summary, the above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the present application shall be included in the protection scope of the present application.
