[0002] When additional peripheral devices need to be installed on a vehicle, the vehicle is usually modified on a large scale to configure an additional power system to specifically power the additional peripheral devices. For example, for a gasoline vehicle, it is necessary to install a generator in the engine compartment of the vehicle to specifically power various on-board peripheral devices (such as vehicle-mounted jammers). Since an additional generator needs to be installed, this power supply method requires a major modification of the vehicle. At the same time, there is a disadvantage that some vehicles do not have enough space for modification.

DETAILED DESCRIPTION

[0056] In order to have a clearer understanding of the technical features, purposes and effects of the embodiments of the present invention, the specific implementation methods of the embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0057] like Figure 1 As shown, the first embodiment of the power supply system of the present invention is disclosed. The power supply system is used to be installed on a movable carrier (not shown in the figure), and the carrier is provided with an external device 300 and a carrier power supply circuit 210 for providing power to the carrier. Figure 1In one embodiment of the power supply system of the present invention shown, the power supply system includes: a parameter adjustment unit 110 and a power conversion unit 120. The parameter adjustment unit 110 connects the carrier power supply circuit 210 and the power conversion unit 120, and the power conversion unit 120 is also used to connect the peripheral device 300. Among them, the parameter adjustment unit 110 is used to obtain the power supply parameters of the carrier power supply circuit 210 to the carrier, and adjust the input parameters of the power conversion unit 120 according to the power supply parameters and the preset working parameters of the carrier power supply circuit 210. The power conversion unit 120 is used to connect the power supply from the carrier power supply circuit 210 according to the input parameters adjusted by the parameter adjustment unit 110, and is used to convert the connected power supply to power the peripheral device 300.

[0058] Specifically, the movable carrier is used to carry objects and to move the objects to achieve the purpose of transportation. Common movable carriers may include vehicles, aircraft and other transportation vehicles. A carrier power supply circuit 210 is provided on the carrier, and the carrier power supply circuit 210 is used to provide working power for the carrier. The specific type of the carrier power supply circuit 210 is determined by the energy type of the carrier, and the embodiment of the present application does not limit this. For example, for a vehicle that uses fuel as an energy type (i.e., an oil truck), the carrier power supply circuit 210 may include at least a vehicle-mounted generator, and for a vehicle that uses a power battery as an energy type (i.e., an electric car), the carrier power supply circuit 210 may include at least a power battery. The carrier power supply circuit 210 can provide power to the functional modules of the vehicle itself. The peripheral device 300 can be a device set on the carrier. The peripheral device 300 can also be powered by the carrier power supply circuit 210 when working. It can be understood that the peripheral device 300 is a device mounted on the carrier, utilizing the mobile characteristics of the carrier and having nothing to do with the working process of the carrier itself. For example, the peripheral device 300 may be a frequency jammer or a signal receiving device. In one embodiment, the power supply system may be used to supply power to a jammer disposed on a vehicle.

[0059] Among them, in the power supply system, the power supply parameters of the vehicle power supply circuit 210 when supplying power to the vehicle are obtained through the parameter adjustment unit 110, and the input parameters of the power conversion unit 120 are adjusted in combination with the preset working parameters of the vehicle power supply circuit 210. In this embodiment, the power supply parameters may be any one or more combinations of parameters such as power supply current, power supply voltage or actual output power, and the power supply parameters may reflect the power required by the current vehicle. That is, the working process of the power conversion unit 120 needs to consider the actual working conditions of the vehicle power supply circuit 210 and the working characteristics of the vehicle power supply circuit 210, so as to avoid the working process of the power conversion unit 120 affecting the power supply of the vehicle by the vehicle power supply circuit 210, and then affecting the normal operation of the vehicle. The preset working parameters, for example, are the maximum power that the vehicle power supply circuit 210 can provide.

[0060] Among them, the power supply parameters corresponding to the vehicle are determined by the working conditions of the vehicle. For example, when the vehicle is in a working condition with a large power consumption, that is, when a large power is required, the corresponding power supply parameters will be large. When the vehicle is in a working condition with a small power consumption, that is, when a small power is required, the corresponding power supply parameters will be relatively small. Therefore, the parameter adjustment unit 110 can determine the size of the current power supply demand of the vehicle according to the size of the power supply parameters, and compare the power supply parameters with the preset working parameters of the vehicle power supply circuit 210 to obtain the current idle power size of the vehicle power supply circuit 210. Idle power can be understood as the power that the vehicle power supply circuit 210 can provide, but is currently idle and has not been output. The parameter adjustment unit 110 can increase, decrease or maintain the input parameters of the power conversion unit 120 according to the idle power, so that the power conversion unit 120 can draw power from the carrier power supply circuit 210 without affecting the power supply of the carrier to the carrier by the carrier power supply circuit 210. For example, the parameter adjustment unit 110 can always control the input parameters of the power conversion unit 120 so that the power obtained by the power conversion unit 120 from the carrier power supply circuit 210 does not exceed the idle power.

[0061] Specifically, when the vehicle requires a larger power consumption, the corresponding idle power will become smaller. At this time, the parameter adjustment unit 110 can adjust the input parameters of the power conversion unit 120 based on the determined smaller idle power, so that the power conversion unit 120 receives a smaller power from the vehicle power supply circuit 120. When the vehicle only requires a smaller power consumption, the corresponding idle power will be relatively large. At this time, the power conversion unit 120 can increase the input parameters of the power conversion unit 120 based on the larger idle power, so that the power conversion unit 120 receives a larger power from the vehicle power supply circuit 120. After the parameter adjustment unit 110 adjusts the input parameters of the power conversion unit 120, the power conversion unit 120 can access the power from the vehicle power supply circuit 210 according to the adjusted input parameters, and the power conversion unit 120 can convert the accessed power to obtain the power supply required by the peripheral device 300, and output the converted power supply to the peripheral device 300. That is, it is finally realized to adjust the power supply to the peripheral device 300 according to the power supply parameters of the vehicle power supply circuit 210.

[0062] Through the above process, the power supply system proposed in the embodiment of the present invention directly draws power from the existing vehicle power supply circuit 210 of the vehicle to power the peripheral device 300. There is no need to install an additional generator, and only the corresponding hardware circuit needs to be added. Therefore, there is no need to make major modifications to the vehicle. In addition, the technical solution of the embodiment of the present invention does not require the modification of the existing vehicle power supply circuit 210 on the vehicle. It can realize the power supply to the peripheral device 300 without affecting the power supply of the vehicle by the vehicle power supply circuit 210. The whole design is simple, the design cost is low, and it can be applied to a variety of different vehicles.

[0063] In one embodiment, if Figure 2 As shown, the parameter adjustment unit 110 includes: a parameter monitoring module 111 and a controller 112. The parameter monitoring module 111 is connected to the vehicle power supply circuit 210, and is used to obtain the power supply parameters of the vehicle by the vehicle power supply circuit 210. The controller 112 is connected to the parameter monitoring module 111 and the power conversion unit 120, and is used to adjust the input parameters of the power conversion unit 120 according to the power supply parameters of the vehicle and the preset working parameters of the vehicle power supply circuit 210.

[0064] Specifically, the specific implementation method of the parameter monitoring module 111 can be determined by the type of power supply parameters monitored, which is not limited in this embodiment. The controller 112 can be implemented by MCU, FPGA, DSP or CPU. In the parameter adjustment unit 110, the power supply process of the vehicle by the vehicle power supply circuit 210 is monitored by the parameter monitoring module 111, so as to realize the monitoring of the power supply parameters of the vehicle by the vehicle power supply circuit 210, so as to obtain the corresponding monitored power supply parameters and input them into the controller 112. The controller 112 can compare the power supply parameters input each time with the power supply parameters input last time, so as to determine whether it is necessary to adjust the current input parameters of the power conversion unit 120 according to the comparison results. For example, if the power supply parameters received this time are consistent with the power supply parameters input last time, it means that there is no need to adjust the input parameters, and the current input parameters for the power conversion unit 120 can be maintained. If the power supply parameters received this time are inconsistent with the power supply parameters input last time, the controller 112 may compare the power supply parameters received this time with the preset working parameters to obtain the input parameters that meet the requirements again, and may use the input parameters to control the power conversion unit 120 to increase or decrease the power connected from the vehicle power supply circuit 210 accordingly, thereby achieving input parameter adjustment of the power conversion unit 120.

[0065] It is understandable that the controller 112 may also directly compare the power supply parameters input each time with the preset working parameters of the vehicle power supply circuit 210 , and adjust the input parameters of the power conversion unit 120 according to the comparison result.

[0066] Simply put, the control process of the power conversion unit 120 can be realized by the controller 112. In a specific embodiment, taking the actual output power as an example of the power supply parameter, when the controller 112 determines that the actual output power of the vehicle power supply circuit 210 to the vehicle increases according to the monitoring parameters of the parameter monitoring module 111, which means that the power required by the vehicle at this time increases, then the idle power that the current vehicle power supply circuit 210 can provide to the peripheral device 300 will become smaller. At this time, in order not to affect the normal operation of the vehicle, the controller 112 correspondingly reduces the input power obtained by the power conversion unit 120 from the vehicle power supply circuit 210 according to the monitoring results of the parameter monitoring module 111. Similarly, when the controller 112 determines that the actual output power of the vehicle power supply circuit 210 to the vehicle is reduced based on the monitoring parameters of the parameter monitoring module 111, it may mean that the power required by the vehicle at this time is reduced. Then the idle power that the current vehicle power supply circuit 210 can provide to the peripheral device 300 will increase. At this time, in order to ensure that the peripheral device 300 is in a better working state, the controller 112 increases the input power obtained by the power conversion unit 120 from the vehicle power supply circuit 210 according to the monitoring results of the parameter monitoring module 111.

[0067] Optionally, in one embodiment, the power supply parameter includes a power supply voltage (this embodiment is not shown separately in the figure), the parameter monitoring module 111 includes a voltage parameter monitoring module, and the voltage parameter monitoring module is used to obtain the power supply voltage of the vehicle. That is, in this embodiment, the parameter monitoring module 111 can obtain the power supply voltage of the vehicle from the vehicle power supply circuit 210 through the voltage parameter monitoring module, and input the obtained power supply voltage to the controller 112, so that the controller 112 adjusts the input parameters of the power conversion unit 120 according to the power supply voltage, and then adjusts the power supply connected to the power conversion unit 120 from the vehicle power supply circuit 210.

[0068] Optionally, in one embodiment, the power supply parameter includes a power supply current (this embodiment is not shown separately in the figure), the parameter monitoring module 111 includes a current parameter monitoring module, and the current parameter monitoring module is used to obtain the power supply current of the vehicle. That is, in one embodiment, the parameter monitoring module 111 can obtain the power supply current of the vehicle from the vehicle power supply circuit 210 through the current parameter monitoring module, and send the obtained power supply current to the controller 112, so that the controller 112 adjusts the input parameters of the power conversion unit 120 according to the power supply current, and then adjusts the power supply connected to the power conversion unit 120 from the vehicle power supply circuit 210.

[0069] In one embodiment, if Figure 3As shown, the power supply parameters may include the power supply voltage and the power supply current at the same time. That is, the voltage parameter monitoring module 1111 and the current parameter monitoring module 1112 are set at the same time to monitor the power supply voltage and the power supply current respectively, so as to obtain the corresponding monitoring results and send them to the controller 112 respectively, so that the controller 112 can adjust the input parameters of the power conversion unit 120 according to the obtained monitoring results. Alternatively, the controller 112 can further calculate other types of power supply parameters, such as actual output power, according to the monitoring results, and then adjust the input parameters of the power conversion unit 120 according to the calculated other types of power supply parameters.

[0070] Optional, such as Figure 4 As shown, the power supply parameter is the actual output power, and the parameter monitoring module 111 includes a power monitoring module 1113. The power monitoring module 1113 is connected to the vehicle power supply circuit 210, and is used to obtain the actual output power of the vehicle power supply circuit 210 to the vehicle 400. The controller 112 is connected to the power monitoring module 1113, and is used to adjust the input power of the power conversion unit 120 connected from the vehicle power supply circuit 21 according to the actual output power of the vehicle power supply circuit 210 to the vehicle 400 and the rated output power of the vehicle power supply circuit 210. The sum of the actual output power and the input power of the power conversion unit 120 is not greater than the rated output power of the vehicle power supply circuit 210.

[0071] Specifically, in the parameter monitoring module 111, the actual output power of the vehicle power supply circuit 210 to the vehicle 400 can be obtained through the power monitoring module 1113, and the idle power of the vehicle power supply circuit 210 can be obtained according to the rated output power of the vehicle power supply circuit 210. The input power of the power conversion unit 120 is controlled according to the idle power. The ultimate goal is to make the input power of the power conversion unit 120 not greater than the idle power of the vehicle power supply circuit 210.

[0072] For example, when the controller 112 determines that the actual output power of the carrier power supply circuit 210 to the carrier 400 increases at this time, it means that the idle power of the carrier power supply circuit 210 decreases, and the controller 112 can adjust the input power of the power conversion unit 210 accordingly, so that the input power of the power conversion unit 120 can always be maintained at no more than the idle power of the carrier power supply circuit 210 as the idle power decreases. When the controller 112 determines that the actual output power of the carrier power supply circuit 210 to the carrier 400 decreases at this time, it means that the idle power of the carrier power supply circuit 210 increases, and the controller 112 can adjust the input power of the power conversion unit 210 accordingly. For example, the input power of the power conversion unit 120 can be made close to the optimal input power of the peripheral device 300, and the increased input power is still made no more than the idle power of the carrier power supply circuit 210. When the controller 112 determines that the actual output power of the vehicle power supply circuit 210 to the vehicle 400 remains unchanged at this time, it means that the idle power stability of the vehicle power supply circuit 210 has not changed. If the input power of the power conversion unit 120 is already the optimal input power of the peripheral device 300 at this time, the input power of the power conversion unit 210 does not need to be adjusted.

[0073] In a specific embodiment, if the vehicle 400 is a vehicle, the vehicle power supply circuit 210 can be a vehicle-mounted generator of the vehicle, wherein the power monitoring module 1113 is connected to the output end of the vehicle-mounted generator to detect the power supply current and power supply voltage output by the vehicle-mounted generator to power the vehicle, and return the detection data to the controller 112, and the controller 112 obtains the real-time output power of the vehicle-mounted generator according to the power supply current and power supply voltage. The controller 112 can also subtract the calculated real-time output power from the rated output power of the vehicle-mounted generator to obtain the idle power of the vehicle. For example, the input end of the power conversion unit 120 is also connected to the vehicle-mounted generator, and the power conversion unit 120 can be implemented by an adapter circuit (DC-DC) constructed by a switch tube, and dynamically draws power from the vehicle-mounted generator under the control of the controller 112. Taking the rated output power of the vehicle-mounted generator as 1900W as an example, under most working conditions, the actual output power of the vehicle-mounted generator is usually only 100W-400W, and there is a large idle power. For example, when the real-time output power of the on-board generator to the vehicle is 400W, the controller 112 is used to dynamically control the PWM signal (i.e., a specific form of input parameter) output to each switch tube in the power conversion unit 120, thereby dynamically adjusting the input power of the power conversion unit 120 to ensure that the total output power of the on-board generator (the sum of the real-time output power to the vehicle 400 and the input power of the power conversion unit 120) does not exceed its rated output power. At this time, the input power of the power conversion unit 120 can be adjusted to 200W. At this time, the total input power of the vehicle and the peripheral device 300 is 600W, which is less than the rated output power of the on-board generator. This process can avoid damage to the on-board generator.

[0074] Optionally, the controller 112 is further configured to adjust the input power of the power conversion unit 120 according to a preset power range of the power conversion unit 120 so that the input power of the power conversion unit 120 is within the preset power range.

[0075] The preset power interval is, for example, a power interval that ensures that the carrier 400 and the peripheral device 300 can be in a working state that meets the requirements at any time. In this embodiment, the input power of the power conversion unit 120 can be set according to the rated output power, the actual output power, and the preset power interval of the carrier power supply circuit 210, so that when the input power of the power conversion unit 120 is adjusted according to the idle power of the carrier power supply circuit 210, the input power of the carrier power supply circuit 210 to the power conversion unit 120 will not exceed the rated output power of the carrier power supply circuit 210, and will not exceed the preset power interval of the power conversion unit 120. When the controller 112 increases the input power of the power conversion unit 120 by adjusting the input parameters of the power conversion unit 120, the input power of the power conversion unit 120 will only be adjusted to the upper limit of the preset power interval at most. Similarly, when reducing the input power of the power conversion unit 120, the input power of the power conversion unit 120 will only be adjusted to the lower limit of the preset power interval at least, that is, the input power of the power conversion unit 120 is always controlled within the preset power interval. For example, the preset power range of the power conversion unit 120 can be 100W-600W, that is, even if the idle power of the carrier 400 is greater than 600W, the power conversion unit 120 can only take a maximum input power of 600W, and at the same time, the power conversion unit 120 can be limited to a minimum of 100W to meet the power supply requirements of the peripheral device 300.

[0076] In this way, it is possible to prevent the power conversion unit 120 from receiving an input power that is too high from the carrier power supply circuit 210, thereby preventing the carrier 400 from having an excessively increased power demand due to the output power of the carrier power supply circuit 210 being excessively occupied, resulting in insufficient power supply to the carrier 400 itself. To a certain extent, it can also prevent the input power of the power conversion unit 120 from being too low, causing the peripheral device 300 to work poorly due to insufficient power supply.

[0077] Optionally, the controller 112 obtains the actual output power of the vehicle power supply circuit 210 to the vehicle 400 according to a first preset frequency, wherein the first preset frequency is greater than or equal to 100 times / second.

[0078] Specifically, when the vehicle power supply circuit 210 supplies power to the vehicle 400, the power demand of the vehicle 400 will change with the change of its working state. When the power demand of the vehicle 400 changes, for example, the power demand increases, if the controller 112 fails to monitor the power demand change in time and adjust the input power of the power conversion unit 120, but still sets the input power of the power conversion unit 120 according to the old monitoring result, it will lead to the inability to adjust the input power of the power conversion unit 120 in time, which may cause the sum of the input power of the vehicle power supply circuit 210 to the peripheral device 300 and the actual output power to the vehicle 400 to be greater than the rated output power of the vehicle power supply circuit 210, and then cause the vehicle power supply circuit 210 to be overloaded. Therefore, in this embodiment, the frequency at which the controller 112 obtains the actual output power is set to a higher frequency (not less than 100 times per second), so that the controller 112 can be approximately set to be able to monitor in real time the actual output power supplied to the vehicle 400 by the vehicle power supply circuit 210, and to perform an adjustment process of the power conversion unit 120 based on the approximately real-time monitoring results, thereby effectively reducing the probability of overloading the vehicle power supply circuit 210 due to untimely acquisition of the actual output power.

[0079] In this embodiment, the frequency at which the controller 112 regulates the input power of the power conversion unit 120 can also be set to a higher frequency to match the first preset frequency.

[0080] Here, the vehicle 400 is taken as a vehicle, and the peripheral device 300 is a vehicle-mounted jammer as a specific embodiment for explanation. During the operation of the vehicle, since the power supply of the vehicle changes frequently, during the power supply process of the vehicle-mounted jammer, the controller 112 should have a high sampling frequency for the detection data fed back by the power monitoring module 1113, and the frequency of controlling the power conversion unit 120 to adjust the power should also be high, for example, the sampling frequency and the adjustment frequency are both greater than 100 times per second, so as to ensure that when the power consumption of the whole vehicle increases suddenly, the controller 112 can monitor and adjust in time, so as to reduce the probability of damaging the generator due to power overload of the vehicle-mounted generator caused by untimely power adjustment of the power conversion unit 120.

[0081] like Figure 5As shown, in one embodiment, the power conversion unit 120 includes a charging module 121 and a first power conversion module 122. The first input end of the charging module 121 is connected to the parameter adjustment unit 110, and the second input end of the charging module 121 is connected to the vehicle power supply circuit 210. The input end of the first power conversion module 122 is connected to the charging module 121, and the output end of the first power conversion module 122 is used to connect to the peripheral device 300. Among them, the charging module 121 is used to adjust the input power connected from the vehicle power supply circuit 210 under the control of the parameter adjustment unit 110. The first power conversion module 122 is used to adjust the output power of the charging module 121 to power the peripheral device 300.

[0082] Specifically, in the power conversion unit 120 , the input power is adjusted by the charging module 121 , and the output power of the charging module 121 is converted by the first power conversion module 122 to obtain the power supply required by the peripheral device 300 .

[0083] like Figure 6 As shown, in one embodiment, the power supply system further includes an external power interface 141, a second power conversion module 142 and a first switching module 143. The input end of the second power conversion module 142 is connected to the external power interface 141, and the first switching module 143 is respectively connected to the output end of the charging module 121, the first output end of the second power conversion module 142, and the input end of the first power conversion module 122. Among them, the first switching module 143 is used to switch the output end of the charging module 121 or the first output end of the second power conversion module 142 to the input end of the first power conversion module 122.

[0084] Specifically, the power supply system can be powered by an external power supply. The external power supply can be connected from an external source such as a power grid, an outdoor power supply, etc. through an external power supply interface 141, and this application does not limit this. The first switching module 143 can be switched under the drive of the parameter adjustment unit 110, specifically, for example, the controller 112 therein, or can also be switched under the drive of other dedicated controllers, and this application does not limit this.

[0085] When it is confirmed that there is an external power supply connected to the external power interface 141, the first switching module 143 can be driven to connect the second power conversion module 142 with the first power conversion module 122, so that the external power can be converted by the second power conversion module 142, and then output to the first power conversion module 122 through the first switching module 143 for power conversion again and then output to the peripheral device 300, thereby realizing the power supply of the peripheral device 300 by the external power. When it is confirmed that there is no external power supply connected to the external power interface 141, the first switching module 143 can be driven to connect the charging module 121 with the first power conversion module 122, and at this time, the vehicle power supply circuit 210 can still be used to power the peripheral device 300.

[0086] In a specific embodiment, the first power conversion module 122 can adopt a DC-DC circuit, and the second power conversion module 142 can be implemented by an AC-DC circuit. The external power interface 141 is used to connect to alternating current, and the second power conversion module 142 is used to convert the external power into a DC voltage and output it to the first power conversion module 122. The first power conversion module 122 is used to convert the connected DC voltage into a DC power supply voltage with an amplitude suitable for the external device 300 to connect to the external device 300, and then power the external device 300.

[0087] In this way, by setting an external power interface 141, a second power conversion module 142 and a first switching module 143, the embodiment of the present invention can make it possible to select an external power supply connected through the external power interface 141, and switch the power input source of the first power conversion module 122 through the first switching module 143 when the vehicle is in a non-moving state and using the peripheral device 300 (for example, the vehicle is in a parking state and the on-board jammer is turned on), so as to realize the use of an external power supply to power the peripheral device 300, so as to save the energy of the vehicle itself, which is beneficial to improving the endurance of the vehicle.

[0088] like Figure 7 As shown, in one embodiment, the power supply system of the embodiment of the present invention further includes an energy storage module 150. The energy storage module 150 is respectively connected to the output end of the charging module 121 and the first switching module 143, and the energy storage module 150 is used to charge through the charging module 121 or to supply power to the first power conversion module 122 through the first switching module 143.

[0089] In this embodiment, when the first switching module 143 connects the charging module 121 and the first power conversion module 122, the input voltage connected to the first power conversion module 122 is jointly determined by the charging module 121 and the energy storage module 150. If the input power of the charging module 121 is low and its output voltage cannot meet the power supply demand of the peripheral device 300 alone, the energy storage module 150 can be in a discharging state, at which time the output voltage of the charging module 121 and the discharge voltage of the energy storage module 150 together constitute the input voltage connected to the first power conversion module 122. If the input power of the charging module 121 is high and its output voltage can meet the power supply demand of the peripheral device 300 alone, the energy storage module 150 can be in a charging state, that is, the energy storage module 150 can also be charged by the charging module 121 at this time, and the output voltage of the charging module 121 is the input voltage connected to the first power conversion module 122. If the charging module 121 has no input power at this time (i.e., the vehicle power supply circuit 210 is not working), the energy storage module 150 may be in a discharging state, and the discharge voltage of the energy storage module 150 is the input voltage connected to the first power conversion module 122, thereby realizing power supply to the first power conversion module 122 through the energy storage module 150.

[0090] It is understandable that when the first switching module 143 is connected to the second power conversion module 142 and the first power conversion module 122 , if the vehicle power supply circuit 210 is in a working state at this time, although the charging module 121 does not supply power to the first power conversion module 122 , it can also charge the energy storage module 150 .

[0091] The energy storage module 150 may include a battery assembly or a capacitor assembly, the battery assembly may be a battery pack, and the capacitor assembly may be a capacitor group composed of multiple supercapacitors. It is understandable that any assembly that can store electrical energy and output the stored electrical energy can be used to implement the energy storage module 150 in the embodiment of the present invention.

[0092] like Figure 8 As shown, in one embodiment, the power supply system of the embodiment of the present invention further includes a second switching module 144. The second switching module 144 is connected to the vehicle power supply circuit 210, the second output end of the second power conversion module 142, and the input end of the charging module 121, and the second switching module 144 is used to switch the vehicle power supply circuit 210 or the second output end of the second power conversion module 142 to the charging module 121.

[0093] Specifically, when the external power interface 141 has an external power input, the second switching module 144 can be controlled to switch the input end of the charging module 121 from being connected to the vehicle power supply circuit 210 to being connected to the second power conversion module 142, so as to form a charging path for the energy storage module 150 from the external power supply, and to charge the energy storage module 150 through the external power supply. When the external power interface 141 does not have an external power input, the second switching module 144 can be controlled to restore the input end of the charging module 121 to be connected to the vehicle power supply circuit 210, so as to switch to charging the energy storage module 150 through the vehicle power supply circuit 210. This process can reduce the power consumption of the vehicle power supply circuit 210.

[0094] Of course, it can be understood that in this embodiment, no matter the first switching module 143 is connected to the first power conversion module 122 and the second power conversion module 142, or is connected to the output end of the first power conversion module 122 and the charging module 121, at this time, the external power source simultaneously charges the energy storage module 150 and powers the peripheral device 300.

[0095] Optional, such as Figure 8 As shown, in one embodiment, the parameter adjustment unit 110 is connected to the second switching module 144 and the first switching module 143, wherein the parameter adjustment unit 110 is used to control the first switching module 143 to connect the first output end of the second power conversion module 142 to the input end of the first power conversion module 122, and disconnect the output end of the charging module 121 from the input end of the first power conversion module 122 when detecting that the external power interface 141 is connected to the external power supply. The parameter adjustment unit 110 is also used to control the second switching module 144 to connect the second output end of the second power conversion module 142 to the input end of the charging module 121, and disconnect the vehicle power supply circuit 210 from the input end of the charging module 121.

[0096] Specifically, the switching process of the first switching module 143 and the second switching module 144 can be controlled by the parameter adjustment unit 110. For example, when the parameter adjustment unit 110 detects that there is an external power input to the external power interface 141, the first switching module 143 and the second switching module 144 can be controlled to switch the power supply system from the vehicle power supply circuit 210 to the external power supply, so that the external power input to the external power interface 141 can be sequentially supplied to the peripheral device 300 via the second power conversion module 142, the first switching module 143 and the first power conversion module 122, and finally realize the external power supply process of the peripheral device 300. At the same time, the external power can also supply power to the energy storage module 150 via the second power conversion module 142, the second switching module 144 and the charging module 121.

[0097] Optional, such as Figure 8 As shown, the parameter adjustment unit 110 is connected to the second switching module 144 and the first switching module 143, wherein the parameter adjustment unit 110 is used to control the first switching module 143 to connect the output end of the charging module 121 with the input end of the first power conversion module 122, and disconnect the first output end of the second power conversion module 142 from the input end of the first power conversion module 122 when it is detected that the external power interface 141 is not connected to the external power supply. The parameter adjustment unit 110 is also used to control the second switching module 144 to disconnect the second output end of the second power conversion module 142 from the input end of the charging module 121, and to connect or disconnect the vehicle power supply circuit 210 from the input end of the charging module 121.

[0098] Specifically, when the parameter adjustment unit 110 detects that there is no external power input, it can confirm again whether the vehicle power supply circuit 210 has power output. When the vehicle power supply circuit 210 has power output, the first switching module 143 and the second switching module 144 can be controlled (at this time, the second switching module 144 disconnects the second output end of the second power conversion module 142 from the input end of the charging module 121, and connects the vehicle power supply circuit 210 to the input end of the charging module 121), so that the vehicle power supply circuit 210 forms a conductive relationship with the peripheral device 300 through the second switching module 144, the charging module 121, the first switching module 143 and the first power conversion module 122, so as to realize the power supply of the vehicle power supply circuit 210 to the peripheral device 300. At the same time, the vehicle power supply circuit 210 can also charge the energy storage module 150 through the charging module 121.

[0099] When the vehicle power supply circuit 210 has no power output, the first switching module 143 and the second switching module 144 can be controlled (at this time, the second switching module 144 disconnects the second output end of the second power conversion module 142 from the input end of the charging module 121, and disconnects the vehicle power supply circuit 210 from the input end of the charging module 121) so that the peripheral device 300 is powered by the energy storage module 150.

[0100] In one embodiment, the first switching module 143 and the second switching module 144 can be controlled to connect the output end of the charging module 121 and the input end of the first power conversion module 122 when there is no external power input and the vehicle power supply circuit 210 has no power output, so that the energy storage module 150 supplies power to the peripheral device 300. At this time, the state of the second switching module 144 is not limited.

[0101] In another embodiment, when there is no external power input but the vehicle power supply circuit 210 has a power output, the first switching module 143 and the second switching module 144 can be controlled so that the second power conversion module 142 and the charging module 121 and the first power conversion module 122 are not conductive, and the charging module 121 and the vehicle power supply circuit 210 are conductive, and the charging module 121 and the first power conversion module 122 are conductive, so that the peripheral device 300 is powered by the vehicle power supply circuit 210 unit and the energy storage module 150 at the same time.

[0102] Optional, such as Fig. 9 and Fig.10 As shown, in one embodiment, the second power conversion module 142 includes a first adapter circuit 1421. The first adapter circuit 1421 is connected to the external power interface 141 and the first switching module 143, and the first adapter circuit 1421 is used to convert the external power connected to the external power interface 141 and then supply power to the peripheral device 300 through the first switching module 143 and the first power conversion module 122.

[0103] exist Fig. 9 and Fig.10 In the illustrated embodiment, the first adapter circuit 1421 can be implemented by an AC-DC circuit, and the corresponding external power interface 141 can be a mains interface. It can be understood that in the second power conversion module 142, the external power supply can be converted into a voltage by the first adapter circuit 1421 to obtain the input voltage required by the first power conversion module 122. In other optional embodiments, the first adapter circuit 1421 can be set according to the power input of the external power interface 141 and the input requirements of the first power conversion module 122.

[0104] Optional, such as Fig. 9 and Fig.10 As shown, the second power conversion module 142 also includes a second adapter circuit 1422. The second adapter circuit 1422 is connected to the external power interface 141 and the second switching module 144, and the second adapter circuit 1422 is used to convert the external power connected to the external power interface 141 and then supply power to the external device 300 through the second switching module 144, the charging module 121, and the first power conversion module 122.

[0105] It can be understood that when it is determined that the external power interface 141 is connected to the external power supply, the first switching module 143 can connect the charging module 121 and the first power conversion module 122, and the second switching module 144 can connect the second adapter circuit 1422 in the second power conversion module 142 to the charging module 121. In the second power conversion module 142, the voltage of the external power connected to the external power interface 114 can be converted by the second adapter circuit 1422 to obtain the input voltage required by the charging module 121, and the charging module 121 works according to the input voltage to supply power to the peripheral device 300 through the first power conversion module 122. In this embodiment, the output of the charging module 121 can simultaneously supply power to the energy storage module 150 and the peripheral device 300 after passing through the first power conversion module 122, that is, the design of the second adapter circuit 1422 can simultaneously consider the charging requirements of the energy storage module 150 and the power supply requirements of the peripheral device 300.

[0106] In one embodiment, the second adapter circuit 1422 is used to charge the energy storage module 150 through the second switching module 144 and the charging module 121 after converting the external power connected to the external power interface 141. It can be understood that in the second power conversion module 142, the voltage of the external power connected to the external power interface 141 can be converted by the second adapter circuit 142 to obtain the input voltage required by the charging module 121, and the charging module 121 can convert the input voltage and output the voltage to charge the energy storage module 150. In this embodiment, when it is determined that the external power interface 141 is connected to the external power, it is only necessary to ensure that the second switching module 144 conducts the second adapter circuit 1422 with the charging module 121, so that the energy storage module 150 can be charged by the external power. For the first switching module 143, if the first adaptation circuit 1421 is connected to the first power conversion module 122, the external power supply will power the peripheral device 300 through the first adaptation circuit 1421, the first switching module 143, and the first power conversion module 122; if the first switching module 143 is changed to connect the charging module 121 to the first power conversion module 122, the output of the charging module 121 from the external power supply can simultaneously power the energy storage module 150 and the peripheral device 300 after passing through the first power conversion module 122.

[0107] exist Fig. 9 and Fig.10 In the illustrated embodiment, the second adaptation circuit 1422 may also be implemented using an AC-DC circuit, and the corresponding external power interface 141 may also be a mains power interface.

[0108] like Fig. 9As shown, in a specific embodiment, the first switching module 143 may include a single-pole double-throw switch SW1, and the second switching module 144 may include a single-pole double-throw switch SW2. The first power conversion module 122 includes an inverter and its peripheral circuits, the peripheral device 300 is a vehicle-mounted jammer, and the controller 112 includes an MCU and its peripheral circuits. Among them, the single-pole double-throw switch SW1 is used to switch the first adapter circuit 1421 and one of the charging modules 121 to be connected to the first power conversion module 122. The single-pole double-throw switch SW2 is used to switch the second adapter circuit 1422 and any one of the vehicle power supply circuit 210 to be connected to the input end of the charging module 121.

[0109] Optional, such as Fig.10 As shown, the first switching module 143 includes a first switch SW31, a second switch SW32, a first diode D1, and a second diode D2. The first end of the first switch SW31 is connected to the output end of the charging module 121, the second end of the first switch SW31 is connected to the anode of the first diode D1, the first end of the second switch SW32 is connected to the first output end of the second power conversion module 142, the second end of the second switch SW32 is connected to the anode of the second diode D2, and the cathode of the first diode D1 and the cathode of the second diode D2 are respectively connected to the input end of the first power conversion module 122.

[0110] Specifically, the first switching module 143 cooperates with the first switch SW31 and the second switch SW32 to switch the first adaption circuit 1421 or the charging module 121 to the first power conversion module 122. The controller 112 can achieve seamless power supply switching control of the input end of the first power conversion module 122 by controlling the first switch SW31 and the second switch SW32.

[0111] When the first switch SW31 is in the on state, when the second switch SW32 needs to be switched on, the second switch SW32 can be controlled to be switched on first, and then the first switch SW31 can be switched off. Since the first power conversion module 122 has been connected to the power supply from the second power conversion module 142 through the second switch SW32 when the first switch SW31 is turned off, the seamless switching of the power supply at the input end of the first power conversion module 122 is achieved, the efficiency of the first diode D1 and the second diode D2 when they are combined is ensured, the energy consumption of the first diode D1 and the second diode D2 can be effectively reduced, and the efficiency is improved.

[0112] Similarly, when the second switch SW32 is in the on state and the first switch SW31 needs to be switched on, the first switch SW31 can be controlled to be turned on first and then the second switch SW32 can be turned off to achieve seamless switching to the power supply connected to the first end of the first switch SW31 to power the input end of the first power conversion module 122.

[0113] In addition, at the moment of switching, when the first switch SW31 and the second switch SW32 are turned on at the same time, although the voltage received by the first switch SW1 and the voltage received by the second switch SW2 are inconsistent, the first diode D1 and the second diode D2 can prevent the current from flowing backwards. That is, when the voltage connected to the first switch SW31 is higher than the voltage connected to the second switch SW32, the second diode D2 can prevent the current of the first switch SW31 from flowing to the second power conversion module 142 through the second switch SW32, so as to protect the second power conversion module 142.

[0114] Similarly, when the voltage connected to the first switch SW31 is lower than the voltage connected to the second switch SW32 , the first diode D1 can prevent the current output by the second power conversion module 142 from flowing to the charging module 121 through the first switch SW31 .

[0115] In a specific embodiment, the controller 112 may be composed of an MCU and its peripheral circuits, and the first power conversion module 122 may be composed of an inverter and its peripheral circuits. The energy storage module 150 may be composed of a battery pack.

[0116] Optionally, based on the above, the parameter adjustment unit 110 is also used to obtain the power supply parameters of the vehicle power supply circuit 210 to the vehicle 400 when it is detected that the external power interface 141 is not connected to the external power supply, so as to adjust the input parameters of the power conversion unit 120 according to the power supply parameters of the vehicle 400 and the preset operating parameters of the vehicle power supply circuit 210.

[0117] It can be understood that when the parameter adjustment unit 110 detects that there is no external power input, the input parameters of the power conversion unit 120 can be adjusted based on the power supply parameters of the vehicle power supply circuit 210 when supplying power to the vehicle 400 obtained through the parameter adjustment unit 110, and combined with the preset working parameters of the vehicle power supply circuit 210. Among them, the preset working parameters can be parameters representing the working characteristics of the vehicle power supply circuit 210. For example, when the vehicle power supply circuit 210 is a vehicle-mounted generator, the preset working parameters can be rated power. That is, the working process of the power conversion unit 120 needs to take into account the actual working conditions of the vehicle power supply circuit 210 and the characteristics of the vehicle power supply circuit 210 itself, so as to avoid the working process of the power conversion unit 120 affecting the power supply of the vehicle power supply circuit 210 to the vehicle 400, thereby affecting the operation of the vehicle 400.

[0118] In an optional embodiment: the parameter adjustment unit 110 may perform corresponding calculations, such as subtraction calculations, on the power supply parameters and the preset operating parameters of the carrier power supply circuit 210 to obtain the difference between the two, and the difference may be used as the idle power supply parameter. The parameter adjustment unit 110 may adjust the input parameters of the power conversion unit 120 according to the idle power supply parameter, so that the power conversion unit 120 may access the corresponding input voltage from the carrier power supply circuit 210 according to the input parameter, and drive the power conversion unit 120 to convert the input voltage to obtain the power supply voltage required by the peripheral device 300.

[0119] Next, Fig. 9 Take this as an example to explain at least part of the working principle of the power supply system:

[0120] 1. When an external power source is connected: If the controller 112 detects that the external power source interface 141 is connected to an external power source, the controller 112 controls the first switching module 143 to switch to a state where the first adapter circuit 1421 and the first power conversion module 122 are connected, and the external power source can supply power to the peripheral device 300. At the same time, the controller 112 controls the second switching module 144 to switch to a state where the second adapter circuit 1422 and the charging module 121 are connected, and the external power source can also supply power to the energy storage module 150 through the second adapter circuit 1422, the second switching module 144, and the charging module 121.

[0121] 2. The situation where the vehicle power supply circuit 210 is powered while the external power supply is not connected: If the controller 112 detects that the external power supply interface 141 is not connected to the external power supply, and the vehicle power supply circuit 210 is normally supplying power to the vehicle 400, the first switching module 143 is controlled to switch to the state where the charging module 121 and the first power conversion module 122 are connected, and at the same time, the second switching module 144 is controlled to switch to the state where the vehicle power supply circuit 210 and the charging module 121 are connected. At this time, the vehicle power supply circuit 210 can supply power to the peripheral device 300, and at the same time, the vehicle power supply circuit 210 will also charge the energy storage module 150. Among them, the current parameter monitoring module 1112 detects the power supply current of the vehicle generator, and the voltage parameter monitoring module 1111 detects the power supply voltage of the vehicle generator. The MCU calculates the actual output power of the vehicle-mounted generator based on the detected power supply voltage and power supply current, and calculates the idle power based on the actual output power and rated output power of the vehicle-mounted generator, thereby controlling the charging module 121 to access a power supply of corresponding power from the vehicle-mounted generator based on the idle power to power the peripheral device 300, and ensure that the power supply power to the peripheral device 300 and the power supply power to the vehicle 400 do not exceed the rated output power of the vehicle-mounted generator.

[0122] 3. The situation where there is no external power supply and the vehicle power supply circuit 210 is not powered: If the controller 112 detects that the external power supply interface 141 is not connected to the external power supply and the vehicle power supply circuit 210 is not powered, the first switching module 143 is controlled to switch to a state where the charging module 121 and the first power conversion module 122 are connected, and the state of the second switching module 144 is not required. At this time, the energy storage module 150 can power the peripheral device 300.

[0123] In addition, an embodiment of the present invention provides an interference system installed on a vehicle, the vehicle includes a vehicle power supply circuit 210, the interference system includes an interference device and a power supply system such as any one of the above, the power supply system is respectively connected to the vehicle power supply circuit 210 and the interference device, wherein the interference device is used to generate an interference signal.

In one embodiment, the interference device may include a vehicle-mounted jammer, which is arranged on the vehicle and is powered by the power supply system described above. When the vehicle-mounted jammer is working, a corresponding interference signal can be generated.

[0124] In addition, a vehicle according to an embodiment of the present invention includes a vehicle power supply circuit 210, a peripheral device 300, and a power supply system as described above.

[0125] In another embodiment, the vehicle includes a vehicle power supply circuit 210 and the above interference system. That is, the interference system can also be set on the vehicle, and the interference system is directly powered by the vehicle power supply circuit 210. In this case, the interference device is in the interference system. It can also be understood that in this embodiment, the vehicle power supply circuit 210 supplies power to the power supply system of the interference system.

[0126] In addition, a vehicle according to an embodiment of the present invention includes a vehicle power supply circuit 210, a peripheral device 300, and a power supply system as described above.

S3, controlling the power conversion unit 120 to access the power supply from the vehicle power supply circuit 210 according to the adjusted input parameters, and powering the peripheral device 300.

[0129] That is, during the operation of the power supply system, the power supply parameters of the carrier power supply circuit 210 to the carrier are first obtained. In the power supply system, the power supply parameters of the carrier power supply circuit 210 when supplying power to the carrier are obtained through the parameter adjustment unit 110, and the input parameters of the power conversion unit 120 are adjusted in combination with the preset working parameters of the carrier power supply circuit 210. That is, the working process of the power conversion unit 120 needs to consider the actual working conditions of the carrier power supply circuit 210 and the working characteristics of the carrier power supply circuit 210, so as to avoid the working process of the power conversion unit 120 affecting the power supply of the carrier power supply circuit 210 to the carrier, and then affecting the operation of the carrier. When the parameter adjustment unit 110 obtains appropriate parameters according to the carrier power supply circuit 210, the input parameters of the power conversion unit 120 are adjusted.

On the basis of the above, when it is determined that there is no external power input in the power supply input of the power supply system, that is, when there is no external power input to the external power interface 141, if there is no power input to the vehicle power supply circuit 210 at the same time, the power supply system can be powered by the energy storage module 150.
