[0001] The present application relates to the technical field of agricultural power supply, in particular to an analog voltage output system, method, medium, program product and terminal. BACKGROUND

[0002] In recent years, with the acceleration of agricultural modernization process and the continuous improvement of technology level, domestic agricultural auxiliary driving system has made remarkable development and progress. With its advanced positioning, navigation and automatic control technology, it can accurately guide agricultural machinery to work according to the preset route, effectively improve the operation accuracy, efficiency and quality of agricultural production, and reduce the labor cost and labor intensity. Due to its increasing maturity and great advantages in agricultural production, the acceptance and popularity of domestic agricultural auxiliary driving system among farmers are rising, and more and more farmers choose to use the system to improve the efficiency of agricultural production.

[0003] However, with the sharp increase in the number of agricultural auxiliary driving systems, various unknown problems have also emerged, which have led to the instability of the system. Among them, the power supply problem is a key factor affecting the stable operation of the system. Different types and brands of agricultural machinery equipped with DC power supply have differences in specifications, parameters and other aspects. Moreover, during use, the power supply will inevitably have different degrees of attenuation and unstable output due to the extension of use time and different use methods. Such unstable power supply brings certain operation risk to the power supply of agricultural auxiliary driving system.

[0004] In order to ensure the reliability and stability of the operation of agricultural auxiliary driving system under different power supply conditions, it is necessary to conduct comprehensive operation test on the system. At present, the commonly used test method is to manually adjust the power supply voltage to simulate different voltage output conditions, so as to observe and evaluate the running state of agricultural auxiliary driving system in the whole voltage variation range.

[0005] However, in the actual operation environment of the field, there are tens of thousands of agricultural auxiliary driving systems in operation. The manual adjustment of voltage output is too simple and fixed to simulate the real and complex power supply operation environment in the field, resulting in a large deviation between the test results and the actual situation, and the potential problems that may exist in the actual use of the system cannot be accurately found. Moreover, manual adjustment of voltage output requires the test personnel to participate in operation and monitoring throughout the process, which is tedious and time-consuming, and the test efficiency is low.

[0022] The embodiments of the present application will be described in detail hereinafter with reference to the drawings, and other advantages and effects of the present application can be easily understood by those skilled in the art from the content disclosed in the present specification. The present application can be implemented or applied in other different specific embodiments, and each detail in the present specification can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] To facilitate understanding of the embodiments of the present application, first, the analog voltage output system according to an embodiment of the present application will be described in conjunction with Figure 1Detailed description. Figure 1 A structural schematic diagram of an analog voltage output system in an embodiment of the present application is shown. The analog voltage output system in this embodiment is connected with the agricultural auxiliary driving system 3 and is used to output analog voltage for the agricultural auxiliary driving system 3 to perform running test; the analog voltage output system comprises a control host computer 1 and a program-controlled power supply 2, the control host computer 1 is connected with the program-controlled power supply 2;

[0024] The control host computer 1 is used to obtain analog voltage by using a sine random algorithm based on the standard output voltage of the agricultural power supply;

[0025] The program-controlled power supply 2 is used to transmit the analog voltage to the agricultural auxiliary driving system 3 for the agricultural auxiliary driving system 3 to perform running test.

[0026] It needs to be explained that the agricultural power supply is used to supply power to the agricultural auxiliary driving system, but in actual application scenarios, the actual output voltage of different agricultural power supplies fluctuates, for example, a variety of nonlinear voltages can be generated in an instant (within 1 millisecond), and such fluctuations will affect the normal operation of the agricultural auxiliary driving system.

[0027] The agricultural auxiliary driving system is not sensitive to all voltage fluctuations, and fluctuations within the normal working voltage range will not affect its performance, and the system can still work normally. However, once there is an instantaneous non-theoretical voltage fluctuation (i.e., a voltage change beyond the normal expectation) or an instantaneous power failure (voltage suddenly drops to zero), it will bring unpredictable effects to the agricultural auxiliary driving system, which may cause the agricultural auxiliary driving system to malfunction or run abnormally.

[0028] In view of the situation that causes the malfunction or abnormal operation of the agricultural auxiliary driving system, it needs to be analyzed and optimized. In the actual field operation environment of the agricultural machine, the agricultural auxiliary driving system cannot obtain practical log files, and the technical personnel are difficult to carry out debugging work on the software system. Without effective data as support, it is difficult to deeply understand the root cause of the problem of the system, and thus it is difficult to optimize and improve the performance of the system. If the manual voltage regulation function in the laboratory is limited, it is difficult to simulate all possible voltage change scenarios in actual operation, which makes it difficult to comprehensively test and solve various problems of the auxiliary driving system caused by voltage fluctuations in actual application in the laboratory environment.

[0029] The simulation voltage output system can accurately reproduce the output voltage characteristics of the agricultural power supply under actual operating conditions and simulate the actual output voltage of the agricultural power supply. The simulation voltage output system can generate voltages with different amplitudes and comprehensively and accurately simulate all possible voltage variation scenarios, providing an actual voltage environment for subsequent operation tests of the agricultural auxiliary driving system.

[0030] During the specific test process, the simulation voltage generated by the simulation voltage output system is transmitted to the agricultural auxiliary driving system. The agricultural auxiliary driving system operates according to the received simulation voltage. In this way, the influence of the actual output voltage on various performance indicators of the agricultural auxiliary driving system under different voltage variation conditions can be systematically tested. This test method breaks through the limitations of traditional test methods, can realize comprehensive evaluation of the agricultural auxiliary driving system under complex voltage environments, effectively improves the test efficiency, and provides strong data support for performance optimization of the agricultural auxiliary driving system.

[0031] In some examples, the program-controlled power supply 2 adopts an ITECH brand program-controlled power supply of IT6723 model. The program-controlled power supply can accurately control and output the simulation voltage within 1 millisecond.

[0032] In this embodiment, the simulation voltage is transmitted to the agricultural auxiliary driving system by the program-controlled power supply, which can accurately control and output the voltage within a time accuracy of 1 millisecond. This is crucial for simulating instantaneous voltage changes and some test scenarios that require high response speed and accuracy of voltage changes, which can greatly improve test efficiency and accuracy. Compared with existing manual test methods, the program-controlled power supply has incomparable advantages. Manual test methods usually rely on manual adjustment of voltage by operators, which not only has slow adjustment speed and cannot meet the needs of rapid changes in testing, but also cannot achieve high-precision voltage control due to human factors, affecting the accuracy and reliability of test results.

[0033] The fast and accurate voltage control capability of the program-controlled power supply not only greatly shortens the test time, but also can obtain more reliable test data. Specifically, when facing large-scale test tasks, the program-controlled power supply can quickly complete the output of simulation voltage, significantly improve the overall test efficiency, and effectively reduce the test cost. Accurate voltage output ensures that the test process of the agricultural auxiliary driving system is completely similar to the actual working scenario, so that more realistic test data can be obtained. These test data provide solid and effective data support for subsequent performance optimization of the agricultural auxiliary driving system, which helps technicians to improve and optimize the system more targetedly, and improves the overall performance and stability of the agricultural auxiliary driving system.

[0034] In an embodiment, the process of obtaining the analog voltage based on the standard output voltage of the agricultural power supply by using the sine random algorithm comprises: obtaining the standard output voltage of the agricultural power supply and the power supply voltage fluctuation range; and calculating the analog voltage with different amplitudes based on the standard output voltage of the agricultural power supply and the power supply voltage fluctuation range in combination with a sine function.

[0035] The standard output voltage of the agricultural power supply refers to the output voltage value of the agricultural power supply under standard working conditions, which is a core parameter in the product specification and is set by the manufacturer during the production of the power supply and generally cannot be changed by the user. Currently, the standard output voltage of the commonly used agricultural power supply is 12V or 24V. However, in actual application, the actual output voltage of the agricultural power supply will be affected by various factors, such as the use environment and use time of the battery, etc., which will cause differences between the actual output voltage and the standard output voltage. The purpose of calculating the analog voltage based on the standard output voltage in this embodiment is to obtain the actual output voltage of the agricultural power supply under various scenarios.

[0036] The power supply voltage fluctuation range is used to simulate the random fluctuation of the power supply voltage. By limiting the power supply voltage fluctuation range, it can be ensured that the analog voltage will not exceed the actual fluctuation range. In this embodiment, the value range of the power supply voltage fluctuation range is 0-5V, for example, the lower limit of the fluctuation is that the analog voltage is not less than 0V, and the upper limit of the fluctuation is that the analog voltage does not exceed the maximum value of the standard output voltage plus 5V. By introducing the parameter of the power supply voltage fluctuation range, the generated analog voltage can be closer to the dynamic change of the output voltage of the agricultural power supply in the actual working scenario, thereby realizing accurate simulation and reproduction of all possible voltage change scenarios.

[0037] In an embodiment, the calculation formula for obtaining the analog voltage with different amplitudes based on the standard output voltage of the agricultural power supply and the power supply voltage fluctuation range in combination with the sine function comprises:

[0038] V=A sin θ+ω; (Formula 1)

[0039] Wherein, V is the analog voltage, A is the standard output voltage of the agricultural power supply, ω is the power supply voltage fluctuation range, and the value range of θ is 0°-90°.

[0040] In this embodiment, the value range of ω is 0-5V. For example, when the standard output voltage of the agricultural power supply is 12V, the output range of the analog voltage calculated according to Formula 1 is 0V-17V; when the standard output voltage of the agricultural power supply is 24V, the output range of the analog voltage calculated according to Formula 1 is 0V-29V. The above calculation formula can be used to control the voltage to simulate the power supply voltage of different agricultural machines.

[0041] In an embodiment, the control host computer 1 is connected with the program-controlled power supply 2 through a serial port. The serial port is an interface for data transmission between devices. This method is simple and direct, and can realize the control and data interaction of the control host computer 1 on the program-controlled power supply 2.

[0042] In an embodiment, the serial port is an RS485 serial port. The RS485 serial port is a standard for serial communication interface, which has the advantages of strong anti-interference ability, long transmission distance, and realization of multi-machine communication, and is widely used in industrial control and other scenes, and is suitable for the communication needs between the control host computer 1 and the program-controlled power supply 2.

[0043] In an embodiment, the control host computer 1 is also used to convert the analog voltage into an analog voltage in the Modbus protocol format.

[0044] It should be noted that the RS485 serial port supports the Modbus communication protocol. Modbus is a communication protocol used for data transmission in serial communication. It is a simple and reliable protocol widely used in industrial automation. Modbus protocol supports multiple data formats, including hexadecimal format. When sending hexadecimal data through Modbus, the data is encoded and decoded in hexadecimal form.

[0045] The control host computer 1 communicates with the program-controlled power supply 2 through the serial port, and the control host computer 1 needs to convert the data into Modbus protocol format. The analog voltage calculated by the control host computer 1 according to the above formula 1 is in decimal format, which is sent to the program-controlled power supply 2 through the serial port in the Modbus communication protocol. At this time, the analog voltage in the decimal format needs to be converted into the analog voltage in the hexadecimal format, which is the analog voltage in the Modbus protocol format, which can facilitate subsequent transmission to the program-controlled power supply 2 through the serial port.

[0046] After the program-controlled power supply 2 receives the hexadecimal format data transmitted based on the Modbus protocol, it can parse it and identify the analog voltage contained in it, and then accurately adjust its voltage output according to the analog voltage, so that the output corresponds to the received analog voltage, thereby realizing precise control and output of the analog voltage.

[0047] It should be emphasized that the analog voltage output system provided by the present application can simulate voltage changes in all scenarios, providing a realistic voltage environment for subsequent operation tests of the agricultural auxiliary driving system, realizing comprehensive evaluation of the agricultural auxiliary driving system in complex voltage environments, effectively improving test efficiency, and providing strong data support for performance optimization of the agricultural auxiliary driving system.
