Patent attributes
Implementations of the present disclosure involve an apparatus and/or method for a modular communication system for use in a tractor trailer to monitor and/or control various components associated within the trailer. In one particular embodiment, the communication system includes encryption/decryption controller boards configured to encrypt/encode messages or signals received at the boards for transmission along a transmission media between the front controller board and rear controller board. Further, one or both of the controller boards may be configured to decrypt/decode messages or signals received at the boards from the other controller board and perform a function in response to the decrypted message. The communication system may also integrate and communicate with several modules within or associated with the trailer, such as sensors, locators, or communication mechanisms.
