[0025] In order to further understand the utility model content, characteristics and effects of the present application, the following examples are given, and the detailed description is as follows in conjunction with the drawings.
[0026] As Figs. 1 to 3 shown, the utility model embodiment provides a kind of integrated CAN intelligent control communication module with adjustable polarity, including mounting plate 1, mounting plate 1 is fixedly connected with mainboard 3, mounting plate 1 is buckled with protective cover 2, mainboard 3 is provided with CAN communication port 4, mainboard 3 is provided with power supply port 5, mainboard 3 is provided with input crimping terminal 6, mainboard 3 is provided with output crimping terminal 7, mainboard 3 is provided with jumper cap 8, jumper cap 8 is used to change terminal output polarity, mainboard 3 is electrically connected with power supply by power supply port 5.
[0027] Further, the utility model embodiment provides a polarity adjustable integrated CAN intelligent control communication module, the polarity of output crimp terminal 7 is changed through the design of jumper cap 8, the compatibility and flexibility of module are greatly improved. This design not only simplifies the polarity matching problem when external equipment is connected, but also reduces the failure risk caused by polarity mismatch. At the same time, the integrated mounting plate 1, mainboard 3 and protective cover 2 structure is compact, easy to install and maintain, improves the stability and reliability of system, ensures the high efficiency and stability of communication, provides ideal communication solution for various application scenarios.
[0028] Specifically, the number of input crimp terminals 6 and output crimp terminals 7 is multiple, and the input crimp terminals 6 and the output crimp terminals 7 are symmetrically distributed.
[0029] Further, the input crimp terminals 6, the output crimp terminals 7, the CAN communication port 4, the jumper cap 8 and the power supply port 5 on the mainboard 3 are all distributed on both sides of the mainboard 3 and arranged neatly, improving the neatness and compactness of the structure.
[0030] Specifically, the input crimp terminals 6 receive input signals and perform standardized processing, which includes denoising, filtering and amplification; the CAN communication port 4 receives the processed data signals; the CAN communication port 4 is electrically connected with the mainboard 3; the CAN communication port 4 follows the CAN communication protocol, converts the data signals into frame format, and outputs to the CAN bus or receives the data frames output by the CAN bus.
[0031] Further, the input crimp terminals 6 of the communication module ensure the high quality and stability of the input signals through standardized processing, and then the CAN communication port 4, which is electrically connected with the mainboard 3, efficiently converts the processed data signals into frame format following the CAN communication protocol and outputs to the CAN bus, realizing fast data transmission. At the same time, the CAN communication port 4 can also receive data frames from the CAN bus, completing bidirectional communication. Not only does it improve the efficiency and accuracy of data transmission, but also enhances the compatibility and flexibility of the communication module, meeting the real-time communication needs in complex environments.
[0032] Specifically, the number of CAN communication ports 4 is two groups, and the two groups of CAN communication ports 4 are symmetrically distributed on the mainboard 3; both groups of CAN communication ports 4 are connected with the input crimp terminals 6 and the output crimp terminals 7 in independent loops respectively, and the two groups of CAN communication ports 4 serve as backups for each other.
[0033] Further, first, the two groups of CAN communication ports 4 are connected with the input crimp terminals 6 and the output crimp terminals 7 in independent loops respectively, ensuring the independence and stability of data transmission, so that even if one loop fails, the other loop can still work normally, greatly improving the reliability and fault tolerance of the system.
[0034] Secondly, the two CAN communication ports 4 are mutually redundant, realizing redundancy design. When the main communication port cannot be used due to failure, the standby communication port can immediately take over the work, ensuring the continuity of communication, avoiding system downtime or data loss caused by communication interruption. In addition, this design also improves the expansibility and flexibility of the communication module, adapts to more diversified application scenarios and needs, and provides more reliable and efficient communication solutions for industrial automation and intelligent control fields.

[0040] (3) 0V power terminal.
[0041] Specifically, when the common end of the jumper cap 8 is connected to the 24V power terminal, the output is PNP signal, and when the common end of the jumper cap 8 is connected to the 0V power terminal, the output is NPN signal.
[0042] Further, the communication module realizes flexible switching of output signal types by adopting the jumper cap 8 design containing 24V power terminal, COM common end pin and 0V power terminal.
[0043] When the common end of the jumper cap 8 is connected to the 24V power terminal, the module outputs PNP signal, which is suitable for application scenarios that require high-level active; and when the common end of the jumper cap 8 is connected to the 0V power terminal, it outputs NPN signal, which is suitable for environments that require low-level active.
[0044] This embodiment not only improves the compatibility and flexibility of the communication module, making it seamlessly interface with different types of control systems and devices, but also simplifies the polarity configuration process. Users can quickly switch signal types by simply adjusting the connection of the jumper cap 8 without changing the circuit or adding additional hardware.
[0045] In summary: the embodiment by setting jumper cap 8 on the mainboard 3, control communication module output crimp terminal 7 polarity, improve the compatibility and flexibility of communication module, also makes it can seamlessly docking a variety of equipment and system.
