Communication module with industrial smart card chip

Abstract

The invention discloses a communication module with an industrial smart card chip, which can improve the reliability of communication. In the communication module, a smart card is packaged with the communication module by dual-in-line packaging technology or surface mount technology, or is packaged in the communication module in a form of an IP core. Compared with the prior art, the communication module of the invention improves the reliability of the communication module because the smart card chip is connected with a wireless communication module or a wired communication module in a mode of welding.

Description

technical field [0001] The invention relates to communication technology, in particular to a communication module with an industrial smart card chip. Background technique [0002] With the wide application of wireless and wired communication modules in the industrial field, the environmental adaptability of the accompanying Subscriber Identity Module (SIM) card has encountered unprecedented challenges. The usual SIM card is a device that is relatively fragile in structure, easy to break, and has limited tolerance to temperature, humidity, pH, vibration and dust. [0003] Most of the existing wireless communication modules use ordinary consumer electronic SIM cards, which are usually packaged with PVC, PET, ABS or PVC and ABS mixed materials, and the pins are usually 6 pins, and there are also 8 pins. [0004] The pin definition of 6-pin or 8-pin SIM card conforms to the specification of ISO7816 integrated circuit card with contacts. combine figure 1 8-pin SIM card pin sch...

AI Technical Summary

Problems solved by technology

Common smart cards such as SIM cards in the prior art often have various problems such as abnormal operation, deformation or poor contact in this environment, resulting in the failure of wireless or wired communication modules to communicate normally.
