Description

Technical Field

[0001] The utility model relates to a data acquisition device, in particular to a ship CAN bus data acquisition device. Background Art

[0002] For example, the company's previous patent application number 202321134942.X discloses a ship energy efficiency data collection box, which concentrates multiple information collection interfaces in one box. There is no need to disperse multiple interfaces. It adopts a modular setting, compact structure, centralized management and deployment, and simple operation. The existing technology uses ship CAN bus data collection to monitor each sub-sensor system in real time to reduce the complexity of wiring.

[0003] The main purpose of ship CAN bus data acquisition is to achieve monitoring, control and optimization of ship systems. The application of CAN in ships began in the early 1990s. In 1994, the German MTUQ company successfully developed the MCS51 monitoring system based on CAN, creating a new era of CAN network ship system application. Since then, CAN networks have been widely used in ship remote control, safety monitoring, voyage analysis, patrol inspection and other systems. The successful application of CAN networks in ship control systems provides a stable and reliable solution to solve the Internet communication problems of ship equipment level such as sensors, actuators, and control modules. However, ships will be affected by external forces such as waves and wind during navigation, which will cause frequent shaking, and the collection device is prone to heat accumulation in the shell during operation, which will affect the normal data collection. Utility Model Content

[0004] The purpose of the utility model is to provide a CAN bus data acquisition device, which has good shock absorption performance and heat dissipation performance.

[0005] The technical solution of the utility model is as follows: a CAN bus data acquisition device comprises a shell provided on the front side of a rear cover, a front cover provided on the front side of the shell, a surface sticker provided on the front cover, a mounting plate arranged in the shell through a shock absorbing mechanism on the rear cover, a CAN bus data acquisition processing module provided on the mounting plate; the shock absorbing module comprises a telescopic rod connected to the mounting plate at one end and connected to the rear cover at the other end, a spring is provided outside the telescopic rod, and a heat dissipation mechanism is provided on one side of the mounting plate.

[0006] In the aforementioned CAN bus data acquisition device, the heat dissipation mechanism includes a rotating shaft arranged on the shell, a fan blade is arranged on the rotating shaft, a coaxially arranged gear is arranged on one side of the fan blade, and a rack corresponding to the gear is arranged on one side of the mounting plate.

[0007] In the aforementioned CAN bus data acquisition device, guide blocks are provided on both sides of the mounting plate.

[0008] In the aforementioned CAN bus data acquisition device, a guide groove corresponding to the guide block is provided in the shell.

[0009] In the aforementioned CAN bus data acquisition device, the front cover and the surface sticker are provided with 2 CAN bus interfaces, 1 RS485 interface and 1 NC interface.

[0010] Compared with the prior art, the utility model uses the telescopic rod to play a guiding and positioning role, and the springs between the telescopic rods can play a shock-absorbing role on the CAN bus data acquisition and processing module, reducing the impact of vibration during ship navigation on the CAN bus data acquisition and processing module, and utilizing the vibration during the operation of the ship to make the gear and rack on the shell produce relative movement, thereby driving the fan blades to rotate and improving the heat dissipation efficiency.

DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0015] Embodiment. A CAN bus data acquisition device is constructed as follows Figure 1-2 As shown, a shell 1 is provided on the front side of a rear cover 2, a front cover 3 is provided on the front side of the shell 1, a surface sticker 4 is provided on the front cover 3, a mounting plate 5 arranged in the shell 1 is provided on the rear cover 2 through a shock absorbing mechanism, and a CAN bus data acquisition and processing module 6 is provided on the mounting plate 5; the shock absorbing module includes a telescopic rod 7 connected to the mounting plate 5 at one end and connected to the rear cover 2 at the other end, a spring 8 is provided outside the telescopic rod 7, and a heat dissipation mechanism is provided on one side of the mounting plate 5.

[0016] The heat dissipation mechanism comprises a rotating shaft 9 arranged on the housing 1 , a fan blade 10 is arranged on the rotating shaft 9 , a coaxially arranged gear 11 is arranged on one side of the fan blade 10 , and a rack 12 corresponding to the gear 11 is arranged on one side of the mounting plate 5 .

[0017] Guide blocks 13 are provided on both sides of the mounting plate 5 .

[0018] The housing 1 is provided with a guide groove 14 corresponding to the guide block 13 .

[0019] The front cover 3 and the surface sticker 4 are provided with two CAN bus interfaces 15 , one RS485 interface 16 and one NC interface 17 .

[0020] Principle of the utility model: The present application is a CAN bus data acquisition device, in particular, a ship CAN bus data acquisition device, which can convert various collected protocols into Ethernet IP / TCP output. The CAN bus data acquisition processing module 6 is a prior art, so it will not be described in detail. The present application is mainly aimed at the CAN bus data acquisition processing module 6 being damaged by frequent and continuous vibrations during the operation of the ship. The present application uses the telescopic rod 7 to play a guiding installation role, and the spring 8 outside the telescopic rod 7 plays a role in absorbing vibration shocks, and uses the relative displacement generated by the mounting plate 5 and the shell 1 during the vibration process as the power of the heat dissipation mechanism. During the movement of the mounting plate 5, the rack 12 will be driven to move, and the rack 12 will cooperate with the gear 11 to drive the gear 11 to move, thereby driving the coaxially arranged fan blades 10 to rotate, so as to achieve a better heat dissipation effect. Compared with the solution of driving the fan blades to rotate with a conventional motor, the influence of motor vibration can be reduced.
