Description

Technical Field

[0001] The present invention relates to the field of device development for sensor product testing, and more particularly to a device development system and method for sensor product testing. Background Art

[0002] In modern industrial production, sensor product testing is a critical step in ensuring product quality and performance. With technological advancements, more and more factories require extensive testing equipment to verify design effectiveness during new product development or pilot testing. These testing processes are often complex and varied, requiring precise control of the sensor product under test and acquisition of its signal output under varying environmental conditions. Consequently, the requirements for test equipment flexibility, variability, and test accuracy are extremely high.

[0003] However, existing sensor product testing systems have some problems and shortcomings in practical applications. First, traditional testing equipment is often only capable of testing specific sensor products and lacks versatility and flexibility. This means that whenever a company needs to test a different type of sensor product, it may need to repurchase or develop dedicated testing equipment, which not only increases costs but also prolongs the testing cycle. Second, existing testing systems have shortcomings in terms of control and monitoring. The operation and monitoring of sensor products during the test process are not intuitive enough, making it difficult to understand the test progress and results in real time. For example, operators usually need to perform multiple operations through a complex operating interface to obtain test data, and the presentation of this data is not intuitive enough, making it difficult to quickly determine whether the test status is normal.

This independent power supply effectively prevents system malfunctions caused by power instability or interference, improving the stability and reliability of the test system. The stable power supply ensures the proper operation of the communication board and PC interface / HMI, ensuring accurate transmission and processing of test signals and enhancing test accuracy and efficiency.

The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0021] It should be understood by those skilled in the art that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] like Figure 1 As shown, on the one hand, a preferred embodiment of the present invention provides a device development system for testing a sensor product, comprising a sensor product to be tested, a communication board, a sensor product, and a PC interface / human-machine interface; The communication board is connected to the sensor product to be tested and is used to guide or instruct the action of the sensor product to be tested; The communication board is also connected to a PC interface / human-machine interface, which receives a control signal and transmits it to the communication board. The communication board controls the sensor product to perform a corresponding action according to the control signal. The communication board monitors the action status of the sensor product and feeds it back to the PC interface / human-machine interface for display; The programmable power supply is connected to the sensor product to supply power to the sensor product.

[0024] In the above technical solution, the PC interface / human-machine interface is connected to the communication board, and the communication board receives the control commands of the PC / human-machine interface through Modbus communication. The PC interface / human-machine interface is connected to the communication board and the PLC controller through Modbus communication.

[0025] The sensor product is controlled to be in working state through the PC interface / human-machine interface. The PC interface / human-machine interface is connected to the PLC controller and communication board through the Modbus serial port interface. The PC first sets the working parameters of the device, such as the Modbus serial port communication rate, slave station number, etc.

[0026] The communication board acts as a slave computer connected to the PC / HMI interface. It establishes a communication connection with the PC / HMI via the Modbus serial port, receives control commands from the PC / HMI, executes actions on the sensor product based on the communication protocol defined within the sensor product, and receives the sensor product's action status, reporting it back to the PC / HMI interface. The communication board can also transmit this interaction data to the user app via LTE for display.

[0027] In actual applications, operators input control signals through a PC / HMI interface. These signals are transmitted to the sensor product via the communication board, and the sensor product then performs corresponding actions based on the received signals. For example, when testing a sensor, the sensor product can adjust operating parameters such as temperature and humidity based on the signals to simulate different operating environments. As the sensor product executes its actions, the communication board monitors its status in real time, such as whether the action is complete and whether there are any anomalies. This status information is then fed back to the PC / HMI interface. The operator can intuitively see the sensor product's execution status through the interface, allowing them to promptly identify and address any issues.

[0028] The collaboration between the communication board, sensor products, and PC / HMI interface enables precise control and real-time monitoring of sensor products, meeting the testing needs of a wide range of sensor products and improving test flexibility and efficiency. The system also provides feedback on the sensor product's execution status to the PC / HMI for display, enabling operators to understand test status in real time and adjust test parameters promptly, ensuring test accuracy and reliability. Furthermore, the inclusion of a programmable power supply provides stable power to the sensor products, further ensuring smooth testing.

[0029] According to a preferred embodiment of the present invention, it also includes a programmable power supply and a PLC controller, the programmable power supply is connected to the PLC controller, the PLC controller is also connected to a PC interface / human-machine interface, the PLC controller receives control commands from the PC / human-machine interface, and controls the programmable power supply voltage according to the control commands.

[0030] In practical applications, operators input the required power supply voltage parameters through a PC interface / human-machine interface. These parameters are transmitted to the programmable power supply via the PLC controller, which then adjusts its output voltage accordingly. For example, when testing electronic equipment with high power supply voltage requirements, operators can set the programmable power supply to output a stable DC voltage through the interface to ensure proper functioning of the equipment during testing. While controlling the programmable power supply, the PLC controller monitors the power supply's output status in real time, such as voltage stability and any abnormal fluctuations, and provides this status information to the PC interface / human-machine interface.

[0031] By introducing a PLC controller and a programmable power supply, precise control of the programmable power supply voltage is achieved. This allows for flexible adjustment of the power supply voltage based on varying test requirements, meeting power supply requirements under a wide range of test conditions. Furthermore, the PLC controller, as the control core, improves the system's automation and control precision, making power supply control more stable and reliable. Furthermore, the PLC controller monitors the status of the programmable power supply in real time, promptly identifying power supply anomalies and providing feedback to operators. This prevents test failures or equipment damage caused by power supply issues, thereby improving the safety and stability of the testing process.

[0032] The PLC controller acts as a strong electrical isolation. Usually, some sensor products have power supply or input and output with high voltage parts, which need to be controlled by the PLC controller. A communication connection is established between the PLC controller and the PC interface / human-machine interface through the Modbus serial port, and the controller receives the control commands sent by the PC interface / human-machine interface. The controller controls the voltage and current of the programmable power supply according to the communication protocol defined within the programmable power supply, receives the voltage and current status feedback from the programmable power supply, and feeds it back to the PC interface / human-machine interface.

[0033] In practical applications, operators can view the status of the programmable power supply in real time through a PC interface or human-machine interface. For example, if the output voltage of the programmable power supply fluctuates, the PLC controller immediately detects this abnormality and issues an alarm through the interface, prompting the operator to take appropriate measures. The PLC controller also records detailed information such as the time and duration of the abnormality, facilitating subsequent troubleshooting and analysis.

[0034] Real-time monitoring of the program-controlled power supply status by the PLC controller enables timely detection of power supply anomalies, preventing test failures or equipment damage due to power problems, and improving the safety and stability of the test process. Simultaneously, monitoring results are fed back to the PC interface / human-machine interface for display, allowing operators to intuitively understand the power supply status and facilitate tracking and recording of the entire test process. This provides strong support for subsequent test analysis and troubleshooting, further improving the reliability and practicality of the test system.

[0035] According to a preferred embodiment of the present invention, the PLC controller also monitors the status of the program-controlled power supply and feeds back the status to the PC / human-machine interface for display.

[0036] According to a preferred embodiment of the present invention, the system further includes a switching power supply A and a switching power supply B. Power supply A powers the communication board, while power supply B powers the PC interface / human-machine interface. This independent power supply arrangement effectively prevents system operation abnormalities caused by power instability or interference.

[0037] In practical applications, both switching power supplies A and B utilize high-performance switching power modules with stable output voltage and current, capable of meeting the power supply requirements of the communication board and the PC interface / human-machine interface. For example, the communication board requires stable power to receive and process control signals. Switching power supply A provides a stable DC power source to ensure the normal operation of the communication board. Similarly, the PC interface / human-machine interface requires stable power to display test information and receive operational commands. Switching power supply B provides a stable AC power source to ensure normal display and operation.

[0038] By equipping the communication board and PC interface / HMI with independent switching power supplies A and B, respectively, we ensure a stable and reliable power supply for both. This independent power supply effectively prevents system malfunctions caused by power instability or interference, improving the stability and reliability of the test system. The stable power supply ensures the proper operation of the communication board and PC interface / HMI, ensuring accurate transmission and processing of test signals and enhancing test accuracy and efficiency. Furthermore, the independent power supply design facilitates system maintenance and troubleshooting, further enhancing the overall performance of the test system.

[0039] According to a preferred embodiment of the present invention, the communication board receives control commands from the PC interface / human-machine interface through Modbus communication. Specifically, the Modbus serial port communication method is adopted, which can replace or increase hardware interfaces such as the network port communication method and the CAN communication method.

[0040] In actual applications, a PC / HMI sends control commands via the Modbus communication protocol. The communication board receives these commands and performs corresponding operations based on the command content. For example, when an operator inputs control signals through the PC / HMI, these signals are transmitted to the communication board via the Modbus communication protocol. The communication board then controls the sensor product to perform the corresponding action based on the signal content. Furthermore, the communication board also uses the Modbus communication protocol to feedback the sensor product's execution status information to the PC / HMI, allowing the operator to understand the test progress and results in real time.

[0041] The Modbus communication protocol enables efficient and reliable communication between the communication board and the PC interface / human-machine interface. The Modbus communication protocol offers excellent compatibility and versatility, ensuring smooth communication between different devices and improving system integration and scalability. Through Modbus communication, the communication board can quickly and accurately receive control commands from the PC interface / human-machine interface and provide timely feedback on the execution status of sensor products, enhancing system control accuracy and response speed. Furthermore, Modbus communication supports a variety of hardware interfaces, such as serial ports, Ethernet ports, and CAN communications, allowing flexible selection based on actual needs. This further enhances the system's adaptability and flexibility, improving the overall performance and ease of operation of the test system.
