Description

Technical Field

[0001] The invention relates to the technical field of automobile performance testing tools, and in particular to a non-wired strobe interval time detection device and method for an automobile turn signal lamp. Background Art

[0002] The detection of the interval time of the non-wired strobing of the automobile turn signal is of great significance. First, it can ensure that the turn signal complies with domestic and international regulatory standards, such as GB 17509-2008, ECE R6, etc., so that the vehicle can be legally on the road, and at the same time adapt to changes in regulations and make timely adjustments to meet new requirements. Secondly, the detection helps to ensure driving safety. The appropriate strobing interval time can improve the warning effect, allowing other road users to clearly understand the driver's intentions and reduce the risk of accidents; if the strobing is abnormal, the turn signal fault can be discovered and repaired in time. In addition, this test plays an important role in optimizing product design and controlling quality for automobile manufacturers. It can provide a basis for design, ensure that the products produced meet quality standards, and improve the efficiency and quality of after-sales maintenance.

[0003] In the prior art, a wired turn signal detection device is used to collect the synchronous strobe time interval of the turn signal. During use, it is usually necessary to directly connect the detection device to the turn signal circuit, and determine the working status of the turn signal by measuring the current, voltage or flash frequency in the circuit. This method often has the following disadvantages: for different vehicles, due to the inconsistency of the vehicle models, for the early non-centralized wiring harness wiring form of vehicles, a strobe receiver wired wiring method is used, and the test method is connected to the turn signal strobe, resulting in the destruction of the wiring harness insulation layer for wiring during the test, and the increase in the workload of disassembling the turn signal line speed wiring, which is inefficient; for the centralized wire control wiring form of the vehicle, because its wiring is more complicated, only the visual strobe plus stopwatch timing method is used, which has low collection accuracy and large human errors.

[0046] By using a non-wired detection device to detect the stroboscopic frequency of vehicle lights, there is no need to perform such disassembly and wiring operations. The touch acquisition module 1 is directly installed on the turn signal lever, and the stroboscopic frequency acquisition module 2 is mounted on the surface of the turn signal to perform detection, which greatly saves the preliminary preparation time and workload and significantly improves the detection efficiency. At the same time, the device is easy to install and does not require complex adjustments or additional disassembly work due to differences in vehicle models, further improving the versatility and convenience of detection, so that it can be efficiently applied to the stroboscopic frequency interval detection of turn signals of various vehicle models.

[0047] like Figure 1 As shown, in this embodiment, the stroboscopic acquisition module 2 includes a shell 21 and a photosensor 22. The shell 21 is used to be mounted on the surface of the turn signal lamp to prevent interference from external light sources. A cavity is formed in the shell 21, and the photosensor 22 is installed in the cavity. The photosensor 22 is communicatively connected with the integrated control box 3 for transmitting the stroboscopic signal to the integrated control box 3.

[0048] The shell 21 of the stroboscopic acquisition module 2 is sleeved on the surface of the turn signal lamp to form a closed cavity, which can effectively block the interference of external light sources and ensure that the photosensitive sensor 22 can only receive the stroboscopic light of the turn signal itself, thereby improving the accuracy of stroboscopic signal acquisition and making the detection result more reliable; the shell 21 not only plays an anti-interference role, but also protects the internal photosensitive sensor 22. The shell 21 can effectively block the invasion of dust and moisture and reduce the impact of vibration on the sensor, thereby extending the service life of the photosensitive sensor 22, enhancing the stability and reliability of the equipment, and reducing the maintenance cost of the equipment; and the shell 21 can play a certain fixing and buffering role, reducing the possibility of such loosening, ensuring that the signal can be stably and continuously transmitted to the integrated control box 3, and avoiding detection failure due to communication interruption or signal loss; at the same time, the detachable installation method facilitates the disassembly and installation of the stroboscopic acquisition module 2.

[0049] Preferably, the housing 21 can be designed and adjusted accordingly according to the shape and size of the turn signal lamps of different vehicle models. Whether it is a common round or square turn signal lamp, or a turn signal lamp of a special shape, the strobe receiver can be adapted and installed by customizing the housing 21. This adaptability enables the detection device to be widely used in various vehicle models, improves the versatility and flexibility of detection, and reduces the detection difficulty and cost caused by differences in vehicle models.

[0050] like Figure 1 and Figure 2 As shown, in this embodiment, the integrated control box 3 includes a network switch 31, and the network switch 31 is respectively connected to the touch acquisition module 1, the photosensitive sensor 22 and the host computer 4 for communication, so that the touch sensor 1 and the photosensitive sensor 22 can transmit the toggle signal and the strobe signal to the network switch 31, and the network switch 31 can transmit the toggle signal and the strobe signal to the host computer 4.

[0051] The network switch 31 provides multiple ports so that the integrated control box 3 can communicate with the touch acquisition module 1, the photosensitive sensor 22 and the host computer 4 through multiple ports at the same time, which simplifies the connection method of the device and improves the communication efficiency of the system, making the data transmission between various devices smoother and more stable; at the same time, the network switch 31 can effectively manage data transmission, reduce data conflicts and congestion, and ensure that data transmission between various devices is more stable and reliable.

[0052] In other embodiments, if more sensors or other detection equipment need to be added, they can be connected through the ports of the network switch 31 without making large-scale changes to the existing system, so that the detection device can flexibly adapt to detection needs of different scales and complexities, thereby improving the versatility and scalability of the system.

[0053] Preferably, the design of the network switch 31 enables the integrated control box 3 to be compatible with a variety of different types of devices, including touch acquisition modules 1, strobe acquisition modules 2 and host computers 4 of different brands and models. This compatibility not only improves the versatility of the system, but also reduces the procurement and maintenance costs of the system, allowing users to choose the most suitable device according to their needs.

[0054] like Figure 1 and Figure 2 As shown, in this embodiment, the integrated control box 3 also includes a digital switch input and output module 32, and the touch acquisition module 1 is communicatively connected to the network switch 31 through the digital switch input and output module 32; the digital switch input and output module 32 is configured to transmit the toggle signal through the network switch 31 to the host computer 4 for processing and display.

[0055] The digital switch input and output module 32 is communicatively connected with the touch acquisition module 1, so that the toggle signal collected by the touch acquisition module 1 can be transmitted to the digital switch input and output module 32, and the digital switch input and output module 32 is communicatively connected with the network switch 31, so that the toggle signal can pass through the touch acquisition module 1, the digital switch input and output module 32, the network switch 31 and the host computer 4 in sequence, so that the signal received by the host computer 4 is accurate, thereby improving the accuracy of the detection result; the digital switch input and output module 32 can ensure the integrity of the signal during the transmission process, reduce data loss or distortion caused by signal interference or transmission errors, and through the processing of digital signals, can improve the anti-interference ability of the device, ensure the stable transmission of the signal, thereby improving the reliability of the system.

[0056] In other embodiments, if more sensors or other detection devices need to be added, they can be connected through the ports of the digital switch input and output module 32 without making large-scale changes to the existing system. This not only improves the scalability of the system, but also reduces the maintenance cost and time of the system.

[0057] like Figure 1 and Figure 2 As shown, in this embodiment, the integrated control box 3 also includes a photoelectric conversion module 33 and a relay module 34. The photoelectric conversion module 33 is communicatively connected with the photosensor 22, and the photoelectric conversion module 33 is used to receive the stroboscopic signal and convert the stroboscopic signal into an electrical signal; the relay module 34 is communicatively connected with the photoelectric conversion module 33 and the digital switch input and output module 32 respectively, and the relay module 34 is configured to transmit the electrical signal from the photoelectric conversion module 33 to the digital switch input and output module 32; the digital switch input and output module 32 is used to convert the electrical signal into a digital signal, and the digital signal is transmitted to the host computer 4 via the network switch 31 for processing and display.

[0058] The two ends of the photoelectric conversion module 33 are respectively connected to the photosensor 22 and the relay module 34 for communication, so that the photoelectric conversion module 33 can receive the stroboscopic signal collected by the photosensor 22, and can convert the stroboscopic signal into an electrical signal, and transmit the electrical signal to the relay module 34. The relay module 34 is connected to the digital switch input and output module 32 for communication, so that the electrical signal can pass through the relay module 34, the digital switch input and output module 32, the network switch 31 and the host computer 4 in sequence, so that the signal received by the host computer 4 is accurate.

[0059] Preferably, the optoelectronic conversion module 33 is an independent module of the integrated control box 3, and its modular design makes the system more convenient for expansion and upgrading. For example, the optoelectronic conversion module 33 of the QSFP-40G-ER4 model has 4 channels, and the pluggable interface transmission rate of each channel is 10Gbps. It is a compact hot-swappable optical module for data communication applications, with four independent optical signal sending and receiving channels, mainly used for high-speed data transmission of switches, routers and data center equipment. If the signal conversion function needs to be optimized or upgraded, it is only necessary to replace or update the optoelectronic conversion module 33, without large-scale changes to the entire integrated control box 3.

[0060] like Figure 1 and Figure 2 As shown, in this embodiment, the integrated control box 3 also includes a power supply module 35, which is installed in the integrated control box 3, and the power supply module 35 is used to supply power to the network switch 31, the touch acquisition module 1, the stroboscopic acquisition module 2, the digital switch input and output module 32, and the relay module 34. The power supply module 35 is installed in the integrated control box 3, and is used to provide a stable power supply to the network switch 31, the touch acquisition module 1, the stroboscopic acquisition module 2, the digital switch input and output module 32, and the relay module 34, which ensures the basis for the normal operation of each module, avoids the instability or failure of the module caused by power fluctuations, and thus improves the stability and reliability of the entire detection system.

[0061] Preferably, the power supply module 35 can be designed to adapt to power supply environments with different voltages and currents, so that the detection device can be used on different types of vehicles without the need for additional power adapters or converters. This design improves the versatility and compatibility of the system and reduces the user's usage cost.

[0062] In summary, in this embodiment, a non-wired strobe interval detection device for a car turn signal light is specifically implemented as follows: before the test, the touch acquisition module 1, the strobe acquisition module 2 and the host computer 4 are respectively connected to the integrated control box 3, and then the strobe acquisition module 2 is mounted on the headlight so that the strobe acquisition module 2 is tightly combined with the headlight, and the touch acquisition module 1 is installed on the turn signal lever. During the test, a force is applied to the touch acquisition module 1. At this time, the touch acquisition module 1 collects a toggle signal so that the force can be transmitted to the turn signal lever, thereby starting the turn signal function, that is, the turn signal synchronously strobes. At this time, the strobe acquisition module 2 collects the strobe signal, and the strobe signal is first converted into an electrical signal through the photoelectric conversion module 33, and the electrical signal is transmitted to the digital switch input and output module 32 through the relay module 34. At the same time, the toggle signal is transmitted to the digital switch input and output module 32, and the digital switch input and output module 32 converts the electrical signal and the toggle signal into a digital signal, and the digital signal is then transmitted to the host computer 4 through the network switch 31, and the host computer 4 processes the digital signal.

[0063] like Figure 3 As shown, in this embodiment, a method for detecting the interval time of a non-wired strobe light of a vehicle turn signal lamp is also included, using a detection device, and the detection method includes the following steps:

[0064] S1: Acquire the toggle signal data and the stroboscopic signal data through the touch acquisition module 1 and the stroboscopic acquisition module 2 respectively;

[0065] S2: The integrated control box 3 converts the stroboscopic signal data into electrical signal data, and transmits the toggle signal data and the electrical signal data to the host computer 4;

[0066] S3: The host computer 4 processes the electrical signal data and the toggle signal data to obtain the first light-on time, the first light-off time and the flash frequency, and takes the time of obtaining the toggle signal data as time 0, and records the experimental time. If the experimental time is equal to the preset experimental time value, the experiment is stopped;

[0067] S4: Compare the first lighting time with the preset lighting time value, compare the first lighting off time with the preset lighting off time value, and compare the flashing frequency with the preset flashing frequency value. If the first lighting time meets the preset lighting time value, the first lighting off time meets the preset lighting off time value and the flashing frequency meets the preset flashing frequency value, then the test is qualified; otherwise, it is unqualified.

[0068] The touch acquisition module 1 and the strobe acquisition module 2 automatically collect the toggle signal and strobe signal of the turn signal, and then the integrated control box 3 and the host computer 4 automatically process and analyze the data, thus realizing the automation of the detection process. This not only improves the detection efficiency, but also reduces the influence of human factors on the detection results, ensuring the consistency and accuracy of the detection results; at the same time, it simplifies the traditional detection process, without the need for complex disassembly and wiring work, and directly uses the non-wired detection device for data collection and analysis, which greatly shortens the detection time, improves the detection efficiency, and makes the detection of turn signals more convenient and efficient.

[0069] Preferably, in this embodiment, the host computer 4 synchronously collects the time interval value of the turn signal flashing, including the following steps:

[0070] 1. The light sensor 22 converts the light changes of the car lights into on / off signals of the relay module 34, and the on / off signals are converted into transmission control protocol TCP data packets through the digital switch input and output module 32. The data packets are sent to the TCP server of the host computer 4 through the network switch 31;

[0071] 2. The TCP server of the host computer 4 parses the data packet, intercepts the valid data in the data packet according to the acquisition protocol, and converts the data into a binary system to obtain the switch signal. The data conversion code language provides functions for processing, converting hexadecimal to binary to confirm the stroboscopic acquisition module or touch collector interface, and then converting hexadecimal to decimal to obtain the acquisition result;

[0072] 3. Each switch signal is stored in an array in sequence, and then in a database, an array queue of all switch signals of the test, with the index value increasing from 0 in sequence until the test ends. At the same time, when the touch switch on the turn signal lever is detected to be touched, the switch electrical signal is transmitted to the digital switch input and output module 32. When the controller converts the switch signal into a TCP data packet, it is sent to the TCP service in the host computer 4 through the network switch 31 to determine whether to start the test. When the test starts, the start time is recorded with the code. After the countdown ends, the collection is stopped and the end time is recorded.
