Description

Technical Field

[0001] This utility model relates to the field of industrial control computer technology, and in particular to a modular industrial control computer. Background Technology

[0002] Industrial control computers, or industrial PCs for short, are core equipment in the field of industrial automation and are widely used in industrial scenarios such as process control, data acquisition, and equipment monitoring. To meet the high reliability requirements of industrial environments, existing industrial PCs generally adopt a modular structure, integrating host modules, I / O modules, communication modules, and other modules into a cabinet to enable rapid replacement and maintenance in case of module failure.

[0003] However, traditional modular industrial PCs typically have the mounting structure placed on both sides of the module, and then the module is installed in the cabinet through the mounting structures on both sides. This setup causes the interface wiring to be obstructed on both sides of the cabinet. Therefore, the expansion interfaces of the module must be centrally located on the front panel of the module. However, due to the limited space on the front panel of the module, the interface expansion capability of a single module is severely restricted, making it difficult to meet the growing demand for multi-device access in modern industrial equipment. Utility Model Content

[0004] The technical problem this invention aims to solve is how to improve the module interface expansion capability of industrial control computers.

[0005] To solve the above-mentioned technical problems, this utility model provides a modular industrial control computer, including a host module and a functional module. The rear panel of the host module extends upward to form a back plate. The back plate is provided with an interface component that connects to the host module. The functional module is connected to the host module after being inserted into the interface component through its rear interface. The functional module is provided with a screw that extends from the front panel to the rear panel. The back plate has a screw hole that matches the screw. The side of the host module and / or the side of the functional module are provided with expansion interfaces.

[0006] Furthermore, there are two functional modules and two interface components on the back panel, which are arranged vertically on the back panel.

[0007] Furthermore, the front panel of the host module and / or the front panel of the functional module are provided with an expansion interface.

[0008] Furthermore, the front end of the screw is thicker than the through hole on the functional module.

[0009] Furthermore, the functional module is an I / O module or a communication module.

[0010] This utility model has the following advantages: the functional module is connected to the host module after being inserted into the interface component of the back plate through its rear interface, and then the screw is screwed into the screw hole on the back plate after passing through the functional module to fix the functional module on the back plate. In this way, the integrated installation of the industrial control computer module can be realized without installing the module in the cabinet. Moreover, the installation structure of the functional module is set on the front panel instead of on the sides of the module. In this way, in addition to setting expansion interfaces on the front panel, the host module and the functional module can also set expansion interfaces on the sides of the module, which improves the module interface expansion capability of the industrial control computer.

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] Example 1

[0018] This embodiment provides a modular industrial control computer, such as Figure 1 As shown, the modular industrial control computer includes a host module 1 and two functional modules 2, such as... Figure 2 As shown, the rear panel of the host module 1 extends upward to form a back plate 3. Two interface components 4 connected to the host module 1 are provided on the back plate 3. These two interface components 4 are arranged vertically on the back plate 3, corresponding to the positions of the two functional modules 2. The rear panel of the functional module 2 is provided with a rear interface 8. The functional module 2 connects to the host module 1 after inserting the interface component 4 through its rear interface 8, thereby realizing the communication connection between the host module 1 and the functional module 2.

[0019] Each functional module 2 has two screws 5 extending from the front panel to the rear panel. The front end of the screw 5 is thicker than the through hole on the functional module 2, allowing it to be secured to the outside of the functional module 2. The back plate 3 has screw holes 6 that fit these screws 5. After the functional module 2 is inserted into the interface component 4 of the back plate 3 through its rear interface 8, the screws 5 can be screwed through the functional module 2 and into the screw holes 6 on the back plate 3 to fix the functional module 2 to the back plate 3. This allows for the integrated installation of the industrial control computer modules without installing the host module 1 and functional modules 2 in a cabinet. Furthermore, the installation structure of the functional module 2 is located on the front panel instead of on the sides of the module. Thus, in addition to the expansion interface 7 on the front panel, the host module 1 and functional modules 2 can also have expansion interfaces 7 on the sides of the module, improving the module interface expansion capability of the industrial control computer. For example, in this embodiment, the host module 1 has expansion interfaces 7 on both the front panel and the side. The first functional module 2 from bottom to top is an I / O module, which has expansion interfaces 7 on both the front panel and the side. The second functional module 2 is a wireless communication module and does not require expansion interfaces 7.

[0020] When functional module 2 malfunctions and needs to be replaced or maintained, the user can first unscrew the screw 5 of the malfunctioning functional module 2, and then disconnect the connection between the rear interface 8 of the functional module 2 and the interface component 4. The malfunctioning functional module 2 can then be removed from the back plate 3 for replacement or maintenance.

[0021] Example 2

[0022] This embodiment provides a modular industrial control computer, such as Figure 3 As shown, the modular industrial control computer differs from Embodiment 1 in that this embodiment only has one functional module 2, and correspondingly, the backplane 3 only has one interface component 4. The host module 1 of this embodiment is the same as that of Embodiment 1, with expansion interfaces 7 on both the front panel and the side. The functional module 2 is an I / O module, with expansion interfaces 7 on both its front panel and the side.

[0023] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
