Description

Technical Field

[0001] The utility model relates to an industrial control computer integrating data acquisition, display and storage with multiple board cards. Background Technique

[0002] Most of the control devices in traditional erection systems, commercial aerospace, industrial control and other fields only have some of the functions of control, display, online testing and data storage. There are few devices that integrate control functions, display functions, online testing functions and data storage functions in the same device. This results in that traditional control devices either lack online detection means or cannot continuously store data for a long time, resulting in insufficient maintainability of control devices and increasing the detection and guarantee cycle of control devices. If you want to achieve an integrated control system with complete functions, you need to select devices with different functions and interconnect them through cables to obtain the required system. This not only increases the research and development cost of the control system, but also increases the installation space of the control system, is not convenient for equipment management, and is not conducive to the miniaturization and intelligent development of the control system. For example, the multi-board card heat dissipation industrial control chassis disclosed in the publication number CN208737376U improves the heat dissipation capacity of the multi-board card chassis by wrapping a heat dissipation plate on the outer wall of the card slot, but a display is not directly provided outside the chassis to display the control interface of the industrial control computer, and an additional connection with the display is required, increasing the volume of the control equipment.
