Description
Technical field
The utility model relates to sound product testing fields, in particular to the sound product testing of CAN bus communication, specifically
Say be a kind of CAN communication sound product function detection device.
Background technique
There is critical role using the audible alarm of CAN communication and suggestion device product in automobile electronics.Due to this
Class product uses the particularity of CAN communication, cannot control product by simply powering on/off in production and detection process
It works normally, it is necessary to which sending corresponding message by specific detection device could work, especially when multiple functions of product are used
Different message control, more increases the difficulty in production detection.It is often artificial using triggering manually in production detection
The mode of judgement checked, this detection mode not only inefficiency and also cannot exclude in artificial judgment it is uncertain because
Element.
According to the relevant test software of CANOPEN, it is corresponding that corresponding different product also needs technical professional to carry out
Secondary development is obtained, cost input is increased significantly, this committed step of artificial judgment may be still unavoidable from.So above scheme
Difficulty is larger, higher cost and the unstable factor there are artificial judgment, it is difficult to which large-scale popularization and application is promoted.
Summary of the invention
The technical problem to be solved by the utility model is to propose a kind of Function detection dress of CAN communication sound product
It sets, the Function detection of CAN communication sound product is made to have many advantages, such as safety, it is economical, easy to maintain, greatly improve product testing
Efficiency, cost, and it is convenient for commercialization and popularization and application.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of function detection device of CAN communication sound product, including the host computer and use for graphical display and operation
In the sound detection module for receiving acoustic information, the host computer is connected with USB-CAN equipment by computer USB interface, described
USB-CAN equipment is connected with testing product by CAN interface, and the testing product receives the specified sound of start of heading sending
Sound, the sound detection module are connected with the MCU for receiving and handling acoustic information, and the MCU is connected with CAN transceiver,
The CAN transceiver is connected to the USB-CAN equipment sound detection infomational message that sends that treated, is returned by USB interface
The host computer is back to carry out analysis judgment and show processing result.
The function of the host computer includes the work of control testing product and differentiates whether display product function is normal.
The model CANalyst- II of the USB-CAN equipment.
The model STM32F0 of the MCU.
The software of the host computer is developed based on LabView.
The CAN transceiver model TJA1050.
The real-time display that the host computer can be realized product test result is stored with synchronous.
The beneficial effects of the utility model are: the utility model examines the triggering work of CAN communication sound product and function
Survey it is integrated, operate it is more convenient, eliminate artificial subjective judgement factor, test result is more accurate；Test mode and survey
Test result is intuitively shown in real time, to increase the reliability of test result；Sound detection device is applied to CAN communication sound
It in product, solves denouncing for such product, realizes that the science of such product testing is intelligent, while this installation cost is relatively low
It is honest and clean, increase the market competitiveness.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure principle chart figure of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
It is further described in face of the utility model.
Functional block diagram as shown in Figure 1:
A kind of function detection device of CAN communication sound product, including for 1 He of graphical display and the host computer of operation
For receiving the sound detection module 4 of acoustic information, the host computer 1 is connected with USB-CAN equipment by computer USB interface
2, the USB-CAN equipment 2 is connected with testing product 3 by CAN interface, and the testing product 3 receives start of heading
Specified sound is issued, the sound detection module 4 is connected with the MCU5 for receiving and handling acoustic information, the MCU5 connection
There is a CAN transceiver 6, the CAN transceiver 6 is connected to the USB-CAN equipment 2 sound detection information report that sends that treated
Text is back to the progress analysis judgment of host computer 1 by USB interface and shows processing result.
Further, the function of the host computer 1 includes the work of control testing product 3 and whether differentiates display product function
Normally.
Further, the model CANalyst- II of the USB-CAN equipment 2.
Further, the model STM32F0 of the MCU5.
