[0002] With the continuous advancement of industrial automation and increasing complexity, more and more industrial control systems are adopting distributed bus control. In a distributed bus control system, each device is independent of each other. A failure in one device does not affect the normal operation of other devices, resulting in a highly stable distributed bus control system. There are many types of fieldbuses in distributed bus control systems, and the CAN bus is one of them. The CAN bus is a multi-master control bus with advantages such as high transmission speed, long communication distance, strong anti-interference performance, and low cost. It is widely used in automotive, marine, and industrial automation applications.

[0016] An analysis method for a CAN bus detection and analysis device, comprising the following steps:

[0017] S1: By pressing the surface of the connecting ring, the push frame can be pushed into the control groove through the push rod so that the push frame leaves the contraction groove. By setting two control mechanisms, the two push frames can be pushed relative to each other in the contraction groove. The curved surface of the outer surface of the push frame abuts the curved surface of the inner wall of the fixed frame, so that the two fixed frames are squeezed and expanded toward the inner wall of the control groove, thereby making the inner wall of the two fixed frames leave the surface of the round rod.

[0018] S2: By loosening the two connecting rings, the return spring can be extended and retracted inside the limit slot, which can drive the return spring and the push frame to reset. Moreover, after the fixed frame enters the contraction slot, the pressure of the extrusion spring can be used to re-clamp the fixed frame to the surface of the round rod through the extrusion spring, thereby preventing the movable mechanism from driving the grip mechanism to slide freely inside the movable slot, thereby completing the adjustment of the grip mechanism.

[0019] S3: After the position of the gripping belt mechanism is adjusted by the connecting frame, the angle of the gripping belt can be adjusted arbitrarily by the connection of the retractable belt through the hinge and the rotational connection of the connecting frame and the surface of the round rod. Moreover, when the user places the palm of the hand holding the device on the rear wall of the main body, the elasticity of the retractable belt can stretch the length of the gripping belt so that the operator's palm can be inserted between the gripping belt and the rear wall of the main body.

[0020] S4: Connect the external data input line through the input port and the connection port to transmit the CAN bus data to the main body for detection and analysis. The progress and results of the CAN bus detection and analysis can be displayed by setting the display screen. At the same time, the function of the main body can be quickly changed through the control button.

[0021] Compared with the prior art, the present invention provides a CAN bus detection and analysis device and analysis method thereof, which has the following beneficial effects:

[0022] 1. The present invention connects an external data input line through the input port and the connection port to transmit the data of the CAN bus to the inside of the main body for detection and analysis. By setting a display screen, the progress and results of the CAN bus detection and analysis can be displayed, which increases the practicality of the device. At the same time, by setting a control button, the function of the main body can be quickly changed, which provides convenience for the use of the device. The main body can be easily placed by the protrusion to avoid direct contact between the main body surface and the ground or desktop, thereby preventing the surface of the main body from being worn due to storage. The belt grip mechanism can be clamped inside the groove when the device is placed by the groove, thereby facilitating the placement of the main body.

[0023] 2. When the device is hand-held, the push frame can be pushed into the control groove through the push rod by pressing the surface of the connecting ring so that the push frame leaves the contraction groove. By setting two control mechanisms, the two push frames can be pushed relative to each other in the contraction groove. The curved surface of the outer surface of the push frame is pressed against the curved surface of the inner wall of the fixing frame, so that the two fixing frames are squeezed and expanded like the inner wall of the control groove, so that the inner wall of the two fixing frames leaves the surface of the round rod. The gripping mechanism can be driven by the connecting frame to adjust the position inside the movable groove, so that the gripping mechanism can be adjusted to different sizes of palms, thereby avoiding the difficulty of placing the palm inside the gripping mechanism to control the main body by hand due to the palm being too small or too large, and by loosening the two connecting rings, the reset spring can be extended and retracted inside the limit groove, which can drive the reset spring and the push frame to reset, and the fixing frame can be re-clamped on the surface of the round rod by the pressure of the extrusion spring after entering the contraction groove through the extrusion spring and the mounting block, thereby avoiding the movable mechanism driving the gripping mechanism to slide arbitrarily inside the movable groove, thereby increasing the stability of hand-holding the main body.

[0024] 3. After the present invention adjusts the position of the gripping belt mechanism through the connecting frame, the angle of the gripping belt can be adjusted at will by the connection of the telescopic belt through the hinge and the rotational connection of the connecting frame and the surface of the round rod, thereby increasing the comfort when the gripping belt fits against the back of the hand, and by the user placing the palm of the hand holding the device on the rear wall of the main body, the elasticity of the telescopic belt can stretch the length of the gripping belt to facilitate the insertion of the operator's palm between the gripping belt and the rear wall of the main body, and the elasticity of the telescopic belt makes the inner wall of the gripping belt fit against the back of the hand, thereby avoiding the phenomenon of the CAN bus detection and analysis device falling due to hand slippage when holding it, avoiding the CAN bus detection and analysis device being broken, thereby causing greater damage to the CAN bus detection and analysis device.

The angle of the gripping band 502 can be adjusted at will by the connection of the telescopic band 501 through the hinge 503 and the rotation connection between the connecting frame 401 and the surface of the round rod 303, thereby increasing the comfort when the gripping band 502 fits against the back of the hand. The elasticity of the telescopic band 501 can stretch the length of the gripping band 502 to facilitate the operator's palm to be inserted between the gripping band 502 and the rear wall of the main body 1. The gripping band 502 is made to fit the inner wall of the gripping band 502 against the back of the hand through the elasticity of the telescopic band 501, thereby avoiding the phenomenon of the CAN bus detection and analysis device falling due to slipping of the hand when held in the hand.

[0040] Working principle: The data of the CAN bus is transmitted to the inside of the main body 1 for detection and analysis by connecting the external data input line through the input port 102 and the connection port 103.

The main body 1 can be placed conveniently through the protrusion 106 to avoid direct contact between the surface of the main body 1 and the ground or desktop, thereby preventing the surface of the main body 1 from being worn due to being placed. The gripping mechanism 5 can be stuck inside the groove 105 when the device is placed, thereby facilitating the placement of the main body 1. The retractable belt 501 is hinged to The connection of the connector 503 and the rotational connection between the connecting frame 401 and the surface of the round rod 303 can arbitrarily adjust the angle of the gripping belt 502, thereby increasing the comfort when the gripping belt 502 fits against the back of the hand, and by the user placing the palm of the hand holding the device on the back wall of the main body 1, the elasticity of the telescopic belt 501 can stretch the length of the gripping belt 502 to facilitate the insertion of the operator's palm between the gripping belt 502 and the back wall of the main body 1, and the elasticity of the telescopic belt 501 makes the inner wall of the gripping belt 502 fit against the back of the hand, thereby avoiding the phenomenon of the CAN bus detection and analysis device falling due to slipping of the hand when holding it, avoiding the CAN bus detection and analysis device being broken, thereby causing greater damage to the CAN bus detection and analysis device.

The outer surface of the pushing frame 603 is arc-shaped, which is counteracted by the arc-shaped surface of the inner wall of the fixing frame 703. The sliding of the pushing frame 603 causes the fixing frame 703 to squeeze or release the round rod 303. By pressing the surface of the connecting ring 604, the pushing frame 603 can be pushed into the control groove 403 through the push rod 601 to make the pushing frame 603 leave the contraction groove 404. By setting two control mechanisms 6, the two pushing frames 603 can be pushed relative to each other in the contraction groove 404. The arc-shaped outer surface of the pushing frame 603 is counteracted by the arc-shaped surface of the inner wall of the fixing frame 703, so that the two fixing frames 703 are squeezed and expanded like the inner wall of the control groove 403;

The outer surface of the side of the push rod 601 away from the connecting ring 604 is an arc shape. There are two control mechanisms 6, and the two control mechanisms 6 are symmetrically distributed with the connecting frame 401 as the center. By loosening the two connecting rings 604, the return spring 602 can be extended and retracted inside the limit groove 405, which can drive the return spring 602 and the push frame 603 to reset;

[0053] S3: After the position of the gripping belt mechanism 5 is adjusted by the connecting frame 401, the angle of the gripping belt 502 can be adjusted arbitrarily by the connection of the retractable belt 501 through the hinge 503 and the rotational connection between the connecting frame 401 and the surface of the round rod 303.
