Description

Technical Field

[0001] This utility model relates to the field of electrical testing, and in particular to a parameter tester for the electromechanical system of armored vehicles. Background Technology

[0002] In traditional electrical testing of armored vehicles, specialized tests targeting vehicle subsystems or components cannot fully reflect the actual condition of the vehicle under dynamic operating conditions, making it difficult to provide effective data references for the optimization and improvement of the vehicle. Therefore, testing instruments for online real-time monitoring of the dynamic operating conditions of armored vehicles are particularly urgent.

[0003] Current methods for conducting electrical tests on armored vehicles primarily involve using measuring instruments such as voltmeters and ammeters to perform starting tests on stationary vehicles and tests on the power grid performance, including power consumption at different speeds. This testing method is inconvenient and unreliable, and has several problems, including the following:

[0004] 1. Voltmeters and ammeters have relatively low sampling rates and most of them have certain filtering processes, so they cannot accurately collect instantaneous peak and surge data of the power grid;

[0005] 2. Testers need to collect data inside the vehicle, which makes synchronous data collection impossible, and the test results are affected by the harsh environment;

[0006] 3. It is impossible to record data in large quantities and quickly, or to plot data trends; the analysis and processing of experimental data relies on manpower, which is labor-intensive and prone to errors.

[0007] 4. Unable to collect state data of the vehicle in motion. Summary of the Invention

[0008] In order to solve the problems existing in the background art, this utility model proposes an armored vehicle electromechanical system parameter tester.

[0009] An electromechanical system parameter tester for armored vehicles includes a main unit housing. The main unit housing includes a housing body and a cover hinged to the housing body. A display panel is provided inside the cover. An integrated keyboard and mouse, an electrical connector, and a push-button switch are respectively provided on the housing body. An embedded board, a data acquisition control board, a data acquisition card, and a current sensor are respectively provided inside the housing body. The current sensor is connected to the embedded board through the data acquisition card. The display panel, the integrated keyboard and mouse, and the push-button switch are respectively connected to the embedded board. The data acquisition card, the data acquisition control board, and the embedded board are respectively connected to the electrical connectors.

[0010] Based on the above, the display panel includes a display panel, a heated glass, a display screen, a fixing plate, and a temperature control switch.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3 As shown, an electromechanical system parameter tester for armored vehicles includes a main unit housing. The main unit housing includes a housing body and a cover hinged to the housing body. A display panel is provided inside the cover. An integrated keyboard and mouse 7, an electrical connector, and a button switch are respectively provided on the housing body 6. An embedded board, a data acquisition control board, a data acquisition card, and a current sensor are respectively provided inside the housing body 6. The current sensor is connected to the embedded board through the data acquisition card. The display panel, the integrated keyboard and mouse 7, and the button switch are respectively connected to the embedded board. The data acquisition card, the data acquisition control board, and the embedded board are respectively connected to the electrical connectors.

[0020] In practice, this also includes communication cables and storage units. Both ends of the cable have plug-in terminals. After connecting the cable to the electrical connector and the object being tested, pressing the button switch starts the tester. The collected test data is processed by the acquisition control board or data acquisition card and then sent to the embedded board. The embedded board outputs the test results through the display panel and simultaneously sends them to the storage unit for storage. Various types of electrical connectors are available, each with multiple channels, capable of simultaneously acquiring, storing, and displaying multiple channels of voltage, current, speed, temperature, and humidity data from armored vehicles in real time. The data is displayed intuitively on the screen, providing convenient human-machine interaction and facilitating operation by testing personnel.

[0021] Specifically, the display panel includes a display panel 1, a heated glass 3, a display screen 5, a fixing plate 4, and a temperature control switch 8. The display panel has an installation opening, and the heated glass 3 is placed inside the installation opening. A rubber strip 2 is provided between the installation opening and the heated glass 3. The display screen 5 is placed on one side of the heated glass 3 and fixed to the display panel 1 by the fixing plate 4. An embedded board is connected to the heated glass 3 and the display screen 5 via the temperature control switch. In other words, the fixing plate presses and fixes the display screen and the heated glass to the display panel. In this embodiment, the fixing plate is fixed to the display panel with screws. The temperature of the heated glass is controlled and adjusted by the temperature control switch to prevent the display screen from fogging due to ambient temperature, which could affect the output display.

[0022] The electrical connectors include power connectors, communication connectors, USB connectors, voltage connectors, and current connectors. The power connectors connect to the embedded board via a push-button switch, controlling the power supply to the tester. In practice, the embedded board has a power conversion circuit to convert the voltage to the required target voltage. The USB connector connects to the embedded board, enabling communication with external devices. The communication connector connects to the embedded board via a data acquisition control board, acquiring one CAN bus data stream and one Flexray bus data stream. The CAN bus baud rate, frame type, address, data byte location, correction factor, and offset can be set using an integrated keyboard and mouse. The voltage connectors connect to the embedded board via the data acquisition control board and data acquisition card. In this embodiment, there are eight voltage connectors. The voltage acquisition circuit uses a common resistor divider circuit to acquire eight voltage streams, with acquisition ranges of 0V to ±100V, 0V to ±500V, and 0V to ±1500V. The current connector connects to the current sensors. In this embodiment, there are six current sensors (models CDL-B50S, CDL-B100S, CDL-B300S, CDL-B500S, CDL-B1000S, and CDL-B2000S), used to collect six current signals. Each current sensor has a range of 50A, 100A, 300A, 500A, 1000A, and 2000A. There are a total of six ranges for the current sensors: 50A, 100A, 300A, 500A, 1000A, and 2000A. During the test, the appropriate current sensor range can be selected based on the different current magnitudes required in the relevant electrical tests of the armored vehicle. For example, during the starting test of an armored vehicle, an inrush starting current of about 800A-1700A will be generated. At this time, a current sensor with a range of 2000A can meet the test requirements. During the heating test of the armored vehicle, the current is relatively small. At this time, a current sensor with a range of 100A can meet the test requirements.

[0023] The enclosure is equipped with temperature and humidity sensors, which are connected to an embedded board for collecting ambient operating temperature data. In this embodiment, the operating temperature is -43℃ to +50℃. A high-precision temperature and humidity transmitter (model TH10S-BH) is used, with a temperature measurement accuracy of ±0.5℃ and a resolution of 0.1℃, and a humidity measurement accuracy of ±5% and a resolution of 0.1rh. This meets the requirements for collecting temperature and humidity data in the test environment during the experiment. The data acquisition card is a USB bus-based card (model USB3200N) with a conversion accuracy of 16 bits. The maximum sampling rate for each channel can be set to 500KHz, which far exceeds the 2KHz sampling rate requirement during startup testing, solving the problem of severe data loss due to excessively low sampling rates during electrical tests of armored vehicles. The control core uses an embedded industrial motherboard (model AIO-3588JQ). This motherboard is small in size and can be easily integrated into a panel or display screen in a small space, optimizing the space utilization of the instrument. In terms of performance, it can meet the requirements of the electromechanical system parameter tester to perform a series of data operations such as real-time display of multi-channel data and data analysis.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
