[0092] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0093] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0094] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the above-mentioned technologies, methods, and equipment should be considered as part of the specification.

[0095] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0096] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0097] First, the application scenario of the present invention is described. The embodiment of the present invention can be applied to antenna control scenarios, especially vehicle-mounted antenna control scenarios.

[0098] In some embodiments, the antenna control system may include an antenna device and a communication device, and the antenna device and the communication device may be connected via a cable (e.g., a coaxial cable or other forms of cables). In this way, the communication device may transmit or receive signals to the antenna device via the cable to achieve vehicle-mounted communication.

[0099] In an optional embodiment, the communication device may send a control signal to the antenna device, and control the antenna device to transmit or receive signals through the control signal. For example, the antenna device may include an antenna component, a signal amplification component, and a microcontroller. The communication device may modulate the control signal and send it to the antenna device. The microcontroller of the antenna device demodulates the control signal to obtain the control signal, and controls the switch state of the signal amplification component according to the control signal to control the antenna device to transmit or receive signals. Among them, the method of modulating the control signal may include an on-off keying (OOK) modulation method.

[0100] However, the control signal is transmitted by modulation and demodulation, which has poor anti-interference ability and high bit error rate. In some scenarios, the communication device and the antenna device can be installed in different positions of the vehicle. For example, the communication device (including the modulator) is installed in the vehicle cab, where the temperature is relatively stable, for example, it can be stable at around 25 degrees; while the antenna device (including the demodulator) is installed on the roof, where the temperature varies greatly due to the influence of sunlight, for example, it may vary between minus 40 degrees Celsius and 150 degrees Celsius. The demodulator frequency drifts with temperature changes, resulting in a high demodulation bit error rate, which affects the reliability of antenna control.

[0101] In order to solve the above technical problems, embodiments of the present utility model provide an antenna device, a communication device, an antenna control system and a vehicle.

[0102] Figure 1 FIG. 1 is a schematic diagram of the structure of an antenna control system provided according to an embodiment. Figure 1 As shown, the antenna control system 1000 may include an antenna device 1100 and a communication device 1200 .

[0103] In some embodiments, the antenna control system may be an antenna control system for satellite communication, for example, the antenna assembly may be an antenna for satellite communication, and the communication device may be a device for satellite communication.

[0104] In other embodiments, the antenna control system can support one or more of satellite communications, 4G, 5G, and 6G.

[0105] In some embodiments, the antenna device 1100 and the communication device 1200 may be connected via a cable, which may be a coaxial cable. For example, the antenna device 1100 may be provided with at least one cable terminal, and the communication device 1200 may also be provided with at least one cable terminal, and the cable connection between the antenna device 1100 and the communication device 1200 may be achieved through the cable terminals at both ends.

[0106] like Figure 1 As shown, an embodiment of the present utility model provides an antenna device. The antenna device 1100 may include:

[0107] Antenna assembly 1110;

[0108] a signal amplifying component 1120, wherein a first signal terminal of the signal amplifying component 1120 is connected to the antenna component 1110, and a second signal terminal of the signal amplifying component 1120 is used to connect to a communication signal terminal of the communication device 1200; and

[0109] The driving circuit 1130 has an input end connected to a control signal end of the communication device 1200 to receive a first electrical signal output by the communication device 1200; the output end of the driving circuit 1130 is connected to a control end of the signal amplifying component 1120, and the driving circuit 1130 is configured to control a switching state of the signal amplifying component 1120 based on the first electrical signal.

[0110] In this embodiment, the antenna device includes an antenna component, a signal amplifying component and a driving circuit, wherein the first signal end of the signal amplifying component is connected to the antenna component, and the second signal end of the signal amplifying component is used to connect to the communication signal end of the communication device; the input end of the driving circuit is used to connect to the control signal end of the communication device to receive the first electrical signal output by the communication device; the output end of the driving circuit is connected to the control end of the signal amplifying component, and the driving circuit is configured to control the switching state of the signal amplifying component based on the first electrical signal. In this way, the switching state of the signal amplifying component is controlled based on the first electrical signal. Since the electrical signal does not need to be modulated, it is simple and reliable, and has a strong anti-interference ability, thereby avoiding the problem of high bit error rate caused by temperature changes and improving the reliability of antenna control.

[0111] In some embodiments, the antenna device may further include a cable terminal, a capacitor and an inductor; wherein:

[0112] The capacitor is connected between the second signal terminal of the signal amplifying component and the cable terminal, and the cable terminal is used to connect the communication signal terminal of the communication device 1200;

[0113] The inductor is connected between the input end of the driving circuit 1130 and the cable terminal, and the cable terminal is also used to connect to the control signal end of the communication device 1200 .

[0114] In one implementation, the communication signal between the communication device and the antenna device is an AC signal (e.g., an AC radio frequency signal), and the control signal between the communication device and the antenna device is a DC signal (e.g., a high level or a low level). The capacitor can filter the DC signal for transmitting the communication signal, and the inductor can filter the AC signal for transmitting the control signal.

[0115] In this way, the antenna device can be connected to the communication signal end and the control signal end of the communication device through a cable terminal, and the communication signal and the control signal can be extracted respectively through the capacitor and the inductor.

[0116] In one implementation, there are M cable terminals, and there are M capacitors and M inductors respectively, where M may be a positive integer greater than or equal to 1.

[0117] For example, if M is 1, the antenna device may include a cable terminal, a capacitor, and an inductor.

[0118] For another example, if M is 2, the antenna device may include two cable terminals (e.g., a first receiving cable terminal and a first transmitting cable terminal), two capacitors (e.g., a first capacitor and a second capacitor), and two inductors (e.g., a first inductor and a second inductor). The first capacitor and the first inductor are respectively connected to the first receiving cable terminal, and the second capacitor and the second inductor are respectively connected to the first transmitting cable terminal.

[0119] In some embodiments, the antenna device may be an active antenna, and the antenna device may include a power conversion component, and the power conversion component may be used to receive the power output of the communication device to power the antenna device. Optionally, the communication device may continuously power the power conversion component of the antenna device, for example, the antenna device may be powered by the above-mentioned coaxial cable, and the power supply voltage may be a preset voltage.

[0120] Figure 2 FIG. 1 is a schematic diagram of the structure of an antenna control system provided according to an embodiment. Figure 2 As shown, the signal amplifying component in the antenna device 1100 of the antenna control system 1000 may include a transmitting signal amplifying component 1122 and a receiving signal amplifying component 1121 .

[0121] In some embodiments, the first signal end of the transmit signal amplifying component 1122 is connected to the antenna component, and the second signal end of the transmit signal amplifying component 1122 is used to connect to the communication signal transmitting end of the communication device.

[0122] In some embodiments, the first signal end of the receiving signal amplifying component 1121 is connected to the antenna component, and the second signal end of the receiving signal amplifying component 1121 is used to connect to the communication signal receiving end of the communication device.

[0123] In some embodiments, the output end of the driving circuit 1130 includes a first output end and a second output end, the first output end of the driving circuit 11301130 is connected to the control end of the transmitting signal amplifying component 1122, and the second output end of the driving circuit 1130 is connected to the control end of the receiving signal amplifying component 1121; the driving circuit 1130 is configured to output a second electrical signal corresponding to the first electrical signal through the first output end, and to output a third electrical signal corresponding to the first electrical signal through the second output end, wherein the second electrical signal is used to control the switching state of the transmitting signal amplifying component 1122, and the third electrical signal is used to control the switching state of the receiving signal amplifying component 1121.

[0124] In this way, the driving circuit can control the switching state of the transmitting signal amplifying component and the receiving signal amplifying component based on the first electrical signal, thereby achieving accurate control of the antenna device, improving the reliability of antenna control, and improving communication efficiency and signal quality.

[0125] In some embodiments, the antenna assembly may include a receiving antenna and a transmitting antenna, the receiving antenna is connected to the receiving signal amplifying assembly, and the transmitting antenna is connected to the transmitting signal amplifying assembly.

[0126] In some embodiments, the transmit signal amplifying component 1122 includes at least one power amplifier PA. The receive signal amplifying component 1121 includes at least one low noise amplifier LNA.

[0127] Optionally, when the PA is turned on (in working state), the power consumption is 2W, and the static current is also 280mA. If the current is always 280mA, the power consumption of 5V voltage is 1.4W. When the PA is turned off (not working state), the power consumption current is only 5mA, and there is basically no heat.

[0128] Optionally, when LNA is turned on (in working state), it has a power consumption of 0.23W, and the static current is also 140mA. If it is always working with a current of 140mA, the power consumption of 3.3V voltage is 0.23W. When LNA is turned off (in non-working state), it has only a power consumption current of 5uA, and basically no heat is generated.

[0129] In this way, the driving circuit controls the switching states of the transmitting signal amplifying component and the receiving signal amplifying component based on the first electrical signal, which can not only meet the timing control requirements of the two-way transmission and reception of satellite communications, but also control the PA of the transmitting signal to have no power consumption and no heat generation when not transmitting a signal, and the LNA of the receiving signal to have no power consumption and no heat generation when not receiving a signal, thereby saving electric energy and eliminating heating.

[0130] In some embodiments, if the voltage value of the first electrical signal is within the first voltage range, the voltage value of the second electrical signal is the first voltage value, and the voltage value of the third electrical signal is the second voltage value; the first voltage value is used to turn on the signal amplification component, and the second voltage value is used to turn off the signal amplification component. In this way, by controlling the voltage value of the first electrical signal to be within the first voltage range, the transmission signal amplification component can be turned on and the reception signal amplification component can be turned off.

[0131] In other embodiments, if the voltage value of the first electrical signal is within the second voltage range, the second electrical signal is the second voltage value, and the third electrical signal is the first voltage value. In this way, by controlling the voltage value of the first electrical signal to be within the second voltage range, the transmitting signal amplifying component can be turned off and the receiving signal amplifying component can be turned on.

[0132] In some other embodiments, if the voltage value of the first electrical signal is within the third voltage range, the second electrical signal and the second electrical signal are both the second voltage value. In this way, by controlling the voltage value of the first electrical signal to be within the third voltage range, the transmitting signal amplifying component and the receiving signal amplifying component can be turned off.

[0133] In some embodiments, the first voltage value may be a low level, such as 0V or less than or equal to 0.7V; the second voltage value may be a high level, such as 5V or 3.3V.

[0134] Optionally, the communication controller of the communication device is also connected to a baseband, and the first voltage value and the second voltage value may be preset voltages, for example, voltages agreed upon with the baseband.

[0135] Among them, the first voltage range, the second voltage range and the third voltage range are all different.

[0136] In some embodiments, it can be determined according to the output voltage of the second DC power supply of the communication device. For example, if the output voltage of the second DC power supply is a first preset voltage, the first preset voltage may be 5V, then: the first voltage range may include greater than 3.3V and less than or equal to 5V, the second voltage range may include greater than 1.6V and less than or equal to 3.3V, and the third voltage range may include less than or equal to 1.67V.

[0137] Optionally, the communication controller of the communication device is also connected to the baseband, and the voltage value of the first electrical signal (e.g., the first voltage range, the second voltage range, and the third voltage range) can be a preset voltage range, for example, a voltage range agreed with the baseband. The higher the voltage value of the first electrical signal, the stronger the anti-interference ability.

[0138] In this way, by precisely controlling the voltage value of the first electrical signal, the transmitting signal amplifying component and the receiving signal amplifying component can be turned on and off, effectively improving the working efficiency and stability of the communication device.

[0148] In some embodiments, Figure 4 As shown, the first power supply circuit 1131 may include a first DC power supply DC1, a first resistor R1, a second resistor R2 and a third resistor R3, wherein:

[0149] The first resistor R1, the second resistor R2 and the third resistor R3 are connected in series between the positive electrode and the negative electrode of the first DC power supply DC1;

[0150] The two power supply output terminals of the first power supply circuit 1131 include:

[0151] A first power supply output terminal connected between the first resistor R1 and the second resistor R2, wherein a voltage value outputted by the first power supply output terminal may be within a second voltage range, for example, may be an upper limit value of the second voltage range;

[0152] The second power supply output terminal is connected between the second resistor R2 and the third resistor R3 , and the voltage value output by the second power supply output terminal may be within the third voltage range, for example, may be the upper limit value of the third voltage range.

[0153] In one implementation, the first resistor R1 , the second resistor R2 , and the third resistor R3 have the same resistance value, for example, all are 1 kilo-ohm, 10 kilo-ohm, or 100 kilo-ohm.

[0154] In one implementation, the output voltage of the first DC power supply may be a first preset voltage, and the first preset voltage may be 5 V. At this time, the voltage output by the first power supply output terminal is 3.3 V, and the voltage output by the second power supply output terminal is 1.67 V. The output voltage of the first DC voltage may be the same as the output voltage of the second DC voltage of the above-mentioned communication device.

[0155] In one implementation, the first direct current power source may be a direct current power converter DC / DC, and the DC / DC may convert the power of the antenna device into the above-mentioned first preset voltage.

[0156] In some embodiments, Figure 4 As shown, the comparison circuit 1132 may include a first comparator U0, a second comparator U1, and a NAND gate A1; wherein:

[0157] The reference voltage input terminals of the first comparator and the second comparator are respectively connected to the two power supply output terminals of the first power supply circuit 1131. The comparison input terminals of the first comparator and the second comparator serve as the input terminals of the driving circuit 1130, and are used to receive the first electrical signal output by the communication device 1200. The output terminal out0 of the first comparator and the output terminal out1 of the second comparator are respectively connected to the two input terminals of the NAND gate.

[0158] The output terminal out1 of the second comparator serves as the first output terminal of the driving circuit 1130 , and the output terminal out2 of the NAND gate serves as the second output terminal of the driving circuit 1130 .

[0159] In one implementation, when the voltage at the comparison input terminal is higher than the voltage at the reference voltage input terminal, the first comparator outputs a second voltage value (e.g., a high level) through the output terminal out0; conversely, when the voltage at the comparison input terminal is lower than the voltage at the reference voltage input terminal, the first comparator outputs a first voltage value (e.g., a low level) through the output terminal out0.

[0160] In one implementation, the second comparator may be an inverting comparator, which outputs a first voltage value through the output terminal out1 when the voltage at the comparison input terminal is higher than the voltage at the reference voltage input terminal; conversely, the second comparator outputs a second voltage value through the output terminal out1 when the voltage at the comparison input terminal is lower than the voltage at the reference voltage input terminal.

[0161] In one implementation, when both input terminals of the NAND gate have the second voltage value, the output terminal has the first voltage value; when any one of the two input terminals of the NAND gate has the first voltage value, the output terminal has the second voltage value.

[0163] If the voltage of the first electrical signal is within the first voltage range (for example, 5V), that is, the voltages of the comparison input terminals of the first comparator and the second comparator are both 5V, then the output terminal of the first comparator is the second voltage value (for example, a high level), and the output terminal of the first comparator is the first voltage value (for example, a low level), and the transmitting signal amplification component can be turned on; the output of the NAND gate is the second voltage value (for example, a high level), and the receiving signal amplification component can be turned off.

[0164] If the voltage of the first electrical signal is within the second voltage range (for example, 3.3V), that is, the voltages of the comparison input terminals of the first comparator and the second comparator are both 3.3V, then the output terminal of the first comparator is the second voltage value (for example, a high level), and the output terminal of the first comparator is the second voltage value (for example, a high level), and the transmitting signal amplification component can be turned off; the output of the NAND gate is the first voltage value (for example, a low level), and the receiving signal amplification component can be turned on.

[0165] If the voltage of the first electrical signal is within the third voltage range (for example, 1.67V), that is, the voltages of the comparison input terminals of the first comparator and the second comparator are both 1.67V, then the output terminal of the first comparator is the first voltage value (for example, a low level), and the output terminal of the first comparator is the second voltage value (for example, a high level), and the transmitting signal amplifying component can be turned off; the output of the NAND gate is the second voltage value (for example, a high level), and the receiving signal amplifying component can be turned off.

[0166] In this way, through the first power supply circuit and the comparator, the switching states of the transmitting signal amplifying component and the receiving signal amplifying component can be controlled based on the first electrical signal.

[0167] In some embodiments, the state switching delays of the first comparator, the second comparator and the NAND gate are all less than or equal to N microseconds, where N is a positive integer. For example, N can be equal to 1 or 10.

[0168] Optionally, the first comparator, the second comparator and the NAND gate may all have nanosecond accuracy.

[0191] In some embodiments, Figure 4 As shown, the communication device 1200 may further include a third direct current power supply DC3 and a fourth inductor L4.

[0192] In one implementation, the fourth inductor L4 is connected between the third DC power supply DC3 and the fourth cable terminal of the communication device 1200. The fourth cable terminal is another cable terminal between the second receiving cable terminal D3 and the second transmitting cable terminal D4 except the third cable terminal. The fourth cable terminal is also used to connect the power conversion component 1140 of the antenna device.

[0193] In some embodiments, Figure 4 As shown, the power conversion component 1140 may include a first DC power converter DC / DC and a second DC voltage converter LDO.

[0229] A fifth power supply output terminal is connected between the fifth resistor R5 and the sixth resistor R6, and a voltage value output by the fifth power supply output terminal is within a third voltage range.

[0230] In one implementation, the fourth resistor R4, the fifth resistor R5 and the sixth resistor R6 have the same resistance value, for example, all are 1 kilo-ohm, 10 kilo-ohm or 100 kilo-ohm.

[0231] In one implementation, the output voltage of the second DC power supply may be a first preset voltage, and the first preset voltage may be 5 V. At this time, the voltage output by the third power supply output terminal is 5 V, the voltage output by the fourth power supply output terminal is 3.3 V, and the voltage output by the fifth power supply output terminal is 1.67 V. The output voltage of the second DC voltage may be the same as the output voltage of the first DC voltage of the above-mentioned antenna device.

[0232] In one implementation, the second direct current power source may be a DC / DC converter, and the DC / DC converter may convert the power of the communication device into the above-mentioned first preset voltage.

[0233] In some embodiments, Figure 7 As shown, the switch circuit 1222 may include a first switch SW1 and a second switch SW2, and the switch control end of the switch circuit 1222 includes a first control end of the first switch SW1 and a second control end of the second switch SW2, the first control end of the first switch is connected to a first control signal output end of the communication controller, and the second control end of the second switch is connected to a second control signal output end of the communication controller; wherein:

[0234] The output end of the first switch SW1 is the output end of the switch circuit 1222 , and the first input end of the first switch SW1 is connected to the output end of the second switch SW2 ;

The third cable terminal is also used to connect the input end of the driving circuit 1130 .

[0252] In this way, the communication device realizes connection with the antenna device by integrating receiving and transmitting cable terminals, capacitors and inductors, so as to reliably control the antenna device and improve the stability and reliability of antenna control.

[0253] In another implementation, the third inductor L3 is connected between the control signal terminal of the communication device 1200 and the third control cable terminal of the communication device 1200, the third control cable terminal is different from the first receiving cable terminal D1 and the first transmitting cable terminal D2, and the third control cable terminal is used to connect the input end of the driving circuit 1130. In this way, the input end of the driving circuit can be connected through a separate cable terminal.

[0254] In some embodiments, Figure 7 As shown, the communication device 1200 may further include a third DC power supply DC3 and a fourth inductor L4.

[0255] In one implementation, the fourth inductor L4 is connected between the third DC power supply DC3 and the fourth cable terminal of the communication device 1200.
