Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A magnetically attached DCS system data interface device includes a data acquisition unit 1. A signal connector 2 is fixedly connected to the upper right side of the data acquisition unit 1. Several connectors 3 are provided on the upper end of the signal connector 2. A support component 4 is inserted and connected to the right side of the data acquisition unit 1. Connecting screws 5 are inserted and connected to the front right side and the rear right side of the data acquisition unit 1. A groove 6 and two slots 7 are opened on the right side of the data acquisition unit 1, and the groove 6 is located between the two slots 7.

[0028] In this embodiment, the support component 4 includes a connecting frame 41, a connecting structure 43 is inserted through the right end of the connecting frame 41, a terminal 44 is fixedly connected to the middle of the right end of the connecting structure 43, and insert plates 42 are fixedly connected to the front and rear of the left end of the connecting frame 41; a data interface 45 is fixedly connected to the left end of the connecting frame 41, a connecting groove 46 is opened on the right end of the connecting frame 41, a data connector 48 is inserted through the inner wall of the connecting groove 46, and the data connector 48 is inserted through the data interface 45; a second magnet 49 is inserted through the front and rear of the right end of the connecting frame 41, and the data interface 45 is inserted through the groove 6; the two second magnets 49 correspond to the positions of the two connecting structures 43 respectively, and the data connector 48 contacts the contact spring 435; the two insert plates 42 are inserted through the two slots 7 respectively.

[0029] The above scheme involves connecting two insert plates 42 to two slots 7 on the data acquisition unit body 1, and connecting the data interface 45 to the slot 6. The position of the support component 4 is positioned by two connecting screws 5. The connecting slot (46) is sleeved with the connecting structure (43) to support the connection process between the connecting structure (43) and the connecting frame (41).

[0030] In this embodiment, the connecting structure 43 includes a connecting plate 431, a locking block 433 is fixedly connected to the rear end of the connecting plate 431, connecting blocks 432 are fixedly connected to both the left and right ends of the connecting plate 431, a third magnet 434 is fixedly connected to the rear end of the locking block 433, a contact spring 435 is fixedly connected to the inner ring wall of the third magnet 434, the locking block 433 is inserted and connected to the connecting frame 41; the third magnet 434 is attracted to the first magnet 47.

[0031] Through the above scheme: the card block 433 is inserted and connected to the connecting groove 46, and the contact spring 435 is in contact with the data connector 48. At the same time, the contact spring 435 and the data connector 48 are fixed by the adsorption process of the first magnet 47 and the third magnet 434, so as to prevent the contact spring 435 and the data connector 48 from falling off during the contact process. The connection between the connecting structure 43 and the connecting frame 41 is strengthened by the adsorption of the two connecting blocks 432 with the two second magnets 49 respectively, thereby improving stability.

[0032] It should be noted that this utility model is a magnetically attached, convenient connection DCS system data interface device. During use, the two insert plates 42 of the support component 4 are aligned with the two slots 7 of the data acquisition unit 1 and inserted to form initial axial positioning. Simultaneously, the data interface 45 on the support component 4 is precisely aligned with the slot 6 of the data acquisition unit 1 to ensure the subsequent data transmission channel is aligned. After pre-positioning, the two connecting screws 5 are passed through the screw holes of the data acquisition unit 1 and the positioning holes of the insert plates 42, respectively, and tightened to achieve rigid locking. During maintenance, only the two connecting screws 5 need to be removed to quickly remove the support component 4 without disassembling the entire device, significantly reducing maintenance time. This is especially suitable for emergency maintenance needs in continuous production scenarios such as chemical and power industries. The connecting structure 43 on the support component 4 is aligned with the connecting frame 41 of the data acquisition unit 1: first, the slot 433 is inserted into the connecting slot 46. The connection structure 43 guides the contact spring 435 to make precise contact with the data connector 48. At the same time, the first magnet 47 built into the connection structure 43 and the third magnet 434 of the data acquisition unit 1 generate a strong magnetic attraction force, pressing the contact spring 435 tightly onto the surface of the data connector 48, preventing the contact from falling off due to vibration or impact, and ensuring the stability of the data transmission link. The two connecting blocks 432 (with built-in permanent magnets) on both sides of the connection structure 43 and the two second magnets 49 on the inner side of the connection frame 41 simultaneously form a second magnetic attraction fixation. After the above positioning and fixing process is completed, the data acquisition unit 1 forms a complete data link through the data interface 45, the contact spring 435 and the data connector 48: the analog signal of the field instrument is transmitted to the data interface 45 through the support component 4, and is transmitted to the data acquisition unit 1 through the reliable contact between the contact spring 435 and the data connector 48. After being converted by the multi-protocol compatible transmission module, it is uploaded to the DCS system.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
