[0036] Figure 1 It is a structural block diagram of a voltage regulation system for engineering equipment provided by the embodiments of this application. As Figure 1 shown, the embodiments of this application provide a voltage regulation system for engineering equipment. The engineering equipment includes a turntable 100, a work bucket 200, and a power transmission component 300. The work bucket 200 and the turntable 100 are connected by a boom. The voltage regulation system may include:

[0037] Power supply 400;

[0038] Electrical components 310, arranged on the work bucket 200 of the engineering equipment;

[0039] The voltage regulating device 210 is arranged on the turntable 100 of the engineering equipment. The input end of the voltage regulating device 210 is connected to the power supply 400, and the output end of the voltage regulating device 210 is connected to the electrical component 310 through the power transmission component 300. It is used to boost the voltage of the power supply 400 input and then output it to the electrical component 310 to supply power to the electrical component 310. Among them, the power transmission component 300 is mainly used for conducting electricity and transmitting the power output by the voltage regulating device 210 to the electrical component 310. The power transmission component 300 can be a cable, a wire, a cable, etc.

[0040] In the embodiment of the present application, the voltage regulating system mainly aims at engineering equipment including a turntable 100, a working bucket 200, and a power transmission component 300, such as a fire truck. The engineering equipment also includes a boom. The turntable 100 and the working bucket 200 are connected by the boom. An electrical component 310 is arranged on the working bucket 200. The power supply 400 usually transmits power to the electrical component 310 through the power transmission component 300. Since the power transmission component 300 is too long and has a large resistance, the voltage output by the power supply 400 is weakened by the power transmission component 300, and the voltage is too low when it reaches the electrical component 310 to meet the power consumption requirements of the electrical component 310. To ensure that the voltage reaching the electrical component 310 can meet the power consumption requirements, a voltage regulating device 210 is newly added to the turntable 100 of the engineering equipment in the embodiment of the present application. The input end of the voltage regulating device 210 is connected to the power supply 400, and the output end is connected to the electrical component 310 through the power transmission component 300. It is used to boost the input voltage of the power supply 400 and then output it to the electrical component 310. In this way, when the voltage rises to an appropriate magnitude, even after being weakened by the power transmission component 300, it can meet the power consumption requirements of the electrical component 310. Compared with the method of increasing the wire diameter of the power transmission component 300 in the prior art, the method of newly adding the voltage regulating device 210 to the turntable 100 in the embodiment of the present application does not significantly change the basic configuration of the engineering equipment and has a lower cost.

[0041] The above technical solution provides a voltage regulating system for engineering equipment. The engineering equipment includes a turntable and a working bucket connected by a boom, and a power transmission component. The voltage regulating system includes a power supply, an electrical component, and a voltage regulating device. The electrical component is arranged on the working bucket, and the voltage regulating device is arranged on the turntable. The input end of the voltage regulating device is connected to the power supply, and the output end of the voltage regulating device is connected to the electrical component through the power transmission component. It is used to boost the power supply input and then output it to the electrical component to supply power to the electrical component. The present application can adjust the voltage output from the power supply to the electrical component through the voltage regulating device, so that the voltage received by the electrical component meets the power consumption requirements. The present application only newly adds a voltage regulating device to the turntable and does not significantly change the structure of the engineering equipment, which is beneficial to reducing costs while meeting the power consumption requirements of the electrical component.

[0042] Figure 2The structural block diagram of a voltage regulating system for engineering equipment provided by another embodiment of the present application. As Figure 2 shown, in the embodiment of the present application, the voltage regulating device 210 may include: a voltage regulating unit 220, the input end of the voltage regulating unit 220 is connected to the power supply 400, and is used for regulating the voltage input by the power supply 400.

[0043] Specifically, to implement the voltage regulating operation, the voltage regulating device 210 may include a voltage regulating unit 220, the input end of the voltage regulating unit 220 is connected to the power supply 400, and the power supply 400 input by the power supply 400 can be regulated. In one example, the voltage regulating unit 220 may adopt an existing voltage regulating device.

[0044] In the embodiment of the present application, the voltage regulating unit 220 may include: a surge suppressor 221, which is used for filtering processing to keep the voltage stable; a booster 222, which is used for raising the input voltage to a high voltage; a boost controller 223, which is used for controlling the boost range of the booster 222.

[0045] Specifically, the voltage regulating unit 220 may include a surge suppressor 221, a booster 222 and a boost controller 223. After the voltage of the power supply 400 enters the voltage regulating unit 220, it is first filtered by the surge suppressor 221. The surge suppressor 221 can filter out surges and clutter, so as to keep the input voltage stable. The surge suppressor 221 is connected to the booster 222, and the voltage processed by the surge suppressor 221 is output to the booster 222. The booster 222 is used for raising the input voltage to a high voltage. To prevent danger caused by an excessive boost range, the voltage regulating unit 220 further includes a boost controller 223. The boost controller 223 is connected to the booster 222 and is used for controlling the boost range of the booster 222, and this range can be set artificially before use.

[0046] In one example, the voltage regulating unit 220 further includes a voltage switching circuit 224 connected to the booster 222, which is used for adjusting the output voltage by means of PWM.

[0047] In one example, the voltage regulating unit 220 further includes a rectifying / filtering circuit connected to the voltage switching circuit 224. The rectifying / filtering circuit 225 is obtained by combining a rectifying circuit and a filtering circuit, and is used for rectifying and filtering the input voltage into a smooth voltage and outputting it. It can be understood that the output end of the rectifying / filtering circuit is connected to the output end of the voltage regulating unit 220, and the output voltage of the rectifying / filtering circuit 225 is the output voltage of the voltage regulating unit 220.

[0048] In one example, the voltage regulating unit 220 further includes an over-temperature protection circuit connected to the boost controller 223, which is used for performing over-temperature protection control on the boost circuit.

[0049] In one example, the voltage regulating device 210 further includes a detection circuit 226 connected to the output terminal of the rectification / filter circuit 225, which is used to detect the output voltage of the rectification / filter circuit 225 and feedback to form a closed-loop control.

[0050] In one example, the voltage regulating device 210 further includes an overvoltage protection circuit 227 connected to the output terminal of the rectification / filter circuit 225, which is used to detect whether the output voltage is overvoltage and perform overvoltage protection.

[0051] In one example, the voltage regulating unit 220 further includes an external voltage regulating controller 228, which is used to receive an external voltage regulating instruction and generate a voltage regulating signal.

[0052] In one example, the voltage regulating unit 220 further includes a PWM control circuit respectively connected to the voltage switching circuit 224, the detection circuit 226, the external voltage regulating controller 228 and the overvoltage protection circuit 227, which is used to receive the signals of the detection circuit 226, the overvoltage protection circuit 227 and the external voltage regulating controller 228, and output a PWM wave to the voltage switching circuit 224.

[0053] In the embodiment of the present application, the voltage regulating device 210 may further include: a redundant power supply unit 230. The input terminals of the redundant power supply unit 230 are respectively connected to the power supply 400 through a first circuit and connected to the voltage regulating unit 220 through a second circuit. The output terminal of the redundant power supply unit 230 is connected to the power transmission element 300 and is used to supply power to the electrical component 310.

[0054] Specifically, the voltage regulating device 210 further includes a redundant power supply unit 230. The redundant power supply unit 230 includes two input terminals, which are respectively connected to the power supply 400 through a first circuit and connected to the voltage regulating unit 220 through a second circuit. The output terminal of the redundant power supply unit 230, that is, the output terminal of the voltage regulating device 210, is connected to the power transmission element 300, so as to supply power to the electrical unit through the power transmission element 300. It can be understood that the output unit of the redundant power supply unit 230 is the larger of the output voltages of the first circuit and the second circuit, that is, the larger of the voltage of the power supply 400 and the output voltage of the voltage regulating unit 220. In this way, direct power supply from the power supply 400 or power supply from the voltage regulating unit 220 can be realized according to the requirements of the engineering equipment.

[0055] In the embodiment of the present application, the voltage regulating device 210 may further include: a circuit on-off control element 240, which is arranged in the circuit where the voltage regulating unit 220 is located and is used to change the on-off state of the circuit of the voltage regulating unit 220.

[0056] Specifically, the voltage regulation system further includes a circuit on-off control element 240, which is disposed in the circuit where the voltage regulation unit 220 is located, i.e., the second circuit, and is used to change the on-off state of the circuit of the voltage regulation unit 220. In one example, the circuit on-off control element 240 may be a power switch or a relay or other components capable of realizing circuit on-off.

[0057] In the embodiment of the present application, the voltage regulation device 210 may further include: a first voltage detection element, which is disposed on the second circuit and is used to detect the output voltage of the voltage regulation unit 220.

[0058] Specifically, the voltage regulation device 210 further includes a first power supply 400 detection element disposed on the second circuit, which is used to detect the output voltage of the voltage regulation unit 220 in real time.

[0059] In the embodiment of the present application, the voltage regulation system may further include: a comparator 320, which is disposed on the work bucket 200 and is connected to the circuit where the input end of the electrical component 310 is located. The input voltage of the non-inverting input end of the comparator 320 is the input voltage of the electrical component 310, and the input voltage of the inverting input end of the comparator 320 is a preset input voltage. The comparator 320 is used to compare the magnitudes of the input voltage of the electrical component 310 and the preset input voltage and output a level signal, and the level signal includes a high-level signal and a low-level signal.

[0060] Specifically, the comparator 320 is a component that can be used to compare the magnitudes of voltages. The comparator 320 includes two input ends and an output end, and the input ends are a non-inverting input end and an inverting input end. In the embodiment of the present application, a comparator 320 is disposed on the work bucket 200 of the engineering equipment. The non-inverting input end of the comparator 320 is connected to the circuit where the input end of the electrical component 310 is located, and the input voltage is the input voltage of the electrical component 310. The input voltage of the inverting input end is the preset input voltage, and the preset input voltage is the required voltage for the normal operation of the electrical component 310 and is a fixed value, which can be manually modified according to the actual situation. It can be understood that when the voltage at the non-inverting input end of the comparator 320 is greater than the voltage at the inverting input end, the output end will output a high-level signal; when the voltage at the non-inverting input end of the comparator 320 is less than the voltage at the inverting input end, the output end will output a low-level signal. Therefore, when the input voltage of the electrical component 310 is greater than the preset input voltage, the comparator 320 outputs a high-level signal; when the input voltage of the electrical component 310 is less than the preset input voltage, the comparator 320 outputs a low-level signal.

[0061] In the embodiment of the present application, the voltage regulation system may further include a work bucket controller 330 connected to the comparator 320. The work bucket controller 330 is used to: receive the high-level signal sent by the comparator 320 and generate a step-down request; or receive the low-level signal sent by the comparator 320 and generate a step-up request.

[0062] Specifically, the voltage regulation system further includes a work bucket controller 330 connected to the comparator 320. The work bucket controller 330 is disposed on the work bucket 200 and can be used to control the operation of the work bucket 200, and can also be used to receive the signal sent by the comparator 320 and generate a voltage regulation request. Since the comparator 320 sending a high-level signal indicates that the input voltage of the electrical component 310 is greater than the preset input voltage, there is an overvoltage risk and voltage reduction is required. At this time, after receiving the high-level signal, the work bucket controller 330 generates a voltage reduction request according to the set logic. If the comparator 320 sends a low-level signal to the work bucket controller 330, it means that the voltage received by the electrical component 310 is too low to meet the normal working requirements and voltage increase is required. At this time, the work bucket controller 330 can generate a voltage increase request according to the set logic. In this way, the situation of the input voltage of the electrical component 310 can be determined through simple logic settings for adjustment.

[0063] In the embodiment of the present application, the voltage regulation system may further include a turntable controller 250 disposed on the turntable 100, which communicates with the work bucket controller 330 and the voltage regulation device 210 respectively. The turntable controller 250 is used for: receiving the voltage increase request sent by the work bucket controller 330 and sending a voltage increase instruction to the voltage regulation device 210; or receiving the voltage reduction request sent by the work bucket controller 330 and sending a voltage reduction instruction to the voltage regulation device 210.

[0064] Specifically, the voltage regulation system further includes a turntable controller 250 disposed on the turntable 100. The turntable controller 250 communicates with the work bucket controller 330 and the voltage regulation device 210 respectively and can be used to control the operation of the turntable 100. In one example, the turntable controller 250 can respond to the voltage regulation request sent by the work bucket controller 330, and its built-in logic is: after receiving the voltage increase request sent by the work bucket controller 330, sending a voltage increase instruction to the voltage regulation device 210; after receiving the voltage reduction request sent by the work bucket controller 330, sending a voltage reduction instruction to the voltage regulation device 210. The built-in logic of the turntable controller 250 can be preset and is a simple control logic.

[0065] In another example, the external voltage regulation controller 228 in the voltage regulation device 210 can respond to the voltage regulation instructions sent by the turntable controller 250, including the voltage increase instruction and the voltage reduction instruction, and generate corresponding PWM signals. In this way, it is beneficial for the subsequent voltage regulation device 210 to achieve flexible voltage regulation according to the input voltage situation of the electrical component 310.

[0066] In the embodiment of the present application, the voltage regulation system may further include: an alarm device, disposed on the turntable 100, for outputting an abnormal voltage warning.

[0067] Specifically, an alarm device is also provided on the turntable 100 of the engineering equipment, which is used to output a voltage abnormality warning when the output voltage is abnormal, so that technicians can handle it in time and improve the safety of the system.

[0068] The above technical solution provides a voltage regulating system for an engineering equipment. The engineering equipment includes a turntable and a working bucket connected by a boom, and a power transmission component. The voltage regulating system includes a power supply, an electrical component and a voltage regulating device. The electrical component is arranged on the working bucket, and the voltage regulating device is arranged on the turntable. The input end of the voltage regulating device is connected to the power supply, and the output end of the voltage regulating device is connected to the electrical component through the power transmission component, and is used to boost the power supply input from the power supply and then output it to the electrical component to supply power to the electrical component. This application can adjust the voltage output from the power supply to the electrical component through the voltage regulating device, so that the voltage received by the electrical component meets the power consumption requirements. This application only adds a voltage regulating device to the turntable and does not significantly change the structure of the engineering equipment, which is beneficial to reducing costs while meeting the power consumption requirements of the electrical component.

[0069] In a specific embodiment of the application, combined with the actual application scenario, the working bucket is used as a multi-functional operation platform. In addition to the basic leveling function, it is also equipped with various subsystems, such as a fire fighting water cannon, a water cannon pan-tilt, a weighing system, a voice intercom, a searchlight system, a fire field monitoring system, etc. These functions are turned on or off according to operation instructions, and sometimes overlap in time cycles, which results in a change in the actual power consumption of the working bucket. If the overlap is serious, there will be a power mutation, which will cause voltage fluctuations. In addition, the instantaneous starting power of motors such as the leveling oil pump and the pan-tilt can reach 2-3 times the rated value, which also exacerbates the voltage fluctuations. Excessive voltage fluctuations and high frequencies have negative impacts on the performance and lifespan of each subsystem. In response to this, the voltage regulating device provided in the embodiment of this application can be combined to solve this problem through further development. For example, on the basis of adjusting the voltage of the working bucket in real time, the action instructions of the working bucket can be read, and the voltage change trend of the working bucket caused by the execution of the instructions can be obtained by analyzing the instructions, and the voltage can be actively and proactively over-adjusted forward or backward according to the predicted results to achieve the purpose of suppressing voltage fluctuations. When it is detected that the working bucket is about to execute a leveling action and the leveling oil pump motor will start in advance, the voltage is increased so that the voltage will not drop too much when the motor starts.

[0070] It should also be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, commodity or equipment including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, commodity or equipment. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, commodity or equipment including the element.

[0071] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
