Problems solved by technology
The noise generated by the rotation of the fan is loud and prone to fatigue, which not only affects the reliability of the monitoring and display equipment, but also, the humid gas in the working environment is easy to corrode the internal components of the monitoring and display equipment through the opening of the casing; at the same time, there is no sealed casing The body directly leads to electromagnetic compatibility radiation and makes the anti-interference ability of monitoring and display equipment poor
In addition, the internal functional modules of the monitoring and display equipment are located on different circuit boards, which makes the internal connection lines of the monitoring and display equipment complicated and greatly increases the probability of human error

Embodiment Construction
[0011] Such as figure 1 , figure 2 As shown, the locomotive monitoring and display device includes a main circuit 11 , an interface circuit 12 , a connecting wire 13 for realizing electrical connection between the two, a housing 14 and a panel 15 .
[0012] Wherein, the main circuit 11 performs calculations according to externally input information and controls the input and output of information, including a central processing unit (CPU), a programmable logic unit (CPLD), a control circuit, an external bus, and the like. In the present invention, the central processing unit adopts an ARM processor with strong processing capability and low calorific value as an example.
[0013] The housing 14 is made of metal, and the housing 14 is divided into a sealed part 141 and a non-sealed part 143 by a partition 142 . The main circuit 11 is placed in the sealed portion 141 of the casing 14 , and the interface circuit 12 is placed in the non-sealed portion 143 of the casing 14 . A c...

The invention discloses a monitoring display device for a locomotive, which at least comprises a main body circuit, an interface circuit, and a shell used for packaging the interface circuit and the main body circuit, wherein the shell is made of a metal material and comprises at least one sealing part and at least one non-sealing part, the sealing part packages the main body circuit, and the non-sealing part packages the interface circuit; and an intercommunicating pore is arranged between the sealing part and the non-sealing part, and a connecting wire between the main body circuit and the interface circuit passes through the intercommunicating pore to realize the electrical connection. The monitoring display device for the locomotive has less heat productivity of a system, and adopts a novel heat dissipation mode at the same time, not only the problem of heat dissipation is solved, but also the sealing part of the shell improves the anti-jamming ability of internal circuits, simultaneously the damage of damp air and dust to internal components is prevented, and the service life of the system can be effectively improved.
Description
【Technical field】 [0001] The invention relates to a display device, in particular to an embedded monitoring display device for locomotives. 【Background technique】 [0002] Locomotive monitoring and display equipment is widely used in various train operation safety monitoring fields at home and abroad, and is the human-computer interaction part of the train operation safety monitoring system. Because locomotives have the characteristics of wide range of use and harsh and changeable operating environments, as an electronic device used in locomotives, locomotive monitoring and display equipment should have the ability to work normally in harsh environments. [0003] With the development of my country's railway industry, the expansion of the scope of railway laying and the increase of train speed, the requirements for locomotive monitoring and display equipment are also increasing. Most of the locomotive monitoring and display devices commonly used in my country currently use f...
