Converter/multiplexer for serial bus
This disclosure relates to a converter/multiplexer and associated method of use therefor or converting and multiplexing parallel inputs, a modem, a GPS, or even modem information into a single multimaster broadcast serial bus standard for connecting electronic control units, and more specifically, to a multiplexer for transforming analog, digital, frequency, GPS, or modem inputs into a CAN bus data transmittal over LAN and/or PAN and interrelation with a similarly equipped receiving module. Further, the converter/multiplexer is used alone or in a group as part of a larger system for multiplexing and demultiplexing signals for serial bus processing and also for guidance when the converters are cabled by operators using stored configurations.
1. A converter for multiplexing multiple inputs to a plurality of buses, the converter comprising:
a central processing unit connected to at least two inputs for receiving parallel data from each of the at least two inputs;
at least a first transceiver connected to the central processing unit for merging the at least two serial inputs into a first serial output format to a serial bus; and
at least a second transceiver connected to the central processing unit for merging the at least two serial inputs into a second serial output format to a CAN bus.
2. The converter of claim 1 , further comprising a third transceiver connected to the central processing unit for merging the at least two serial inputs into a third serial output format to either a wireless antenna or a SNA connector, for transmitting the serial output via a wireless protocol.
3. The converter of claim 2 , wherein the transmission over the serial output is for an optical cable, or an Ethernet over twisted cable.
4. The converter of claim 1 , further comprising a third transceiver for transmitting the serial output of the third transceiver over a protocol taken from a group consisting of a local area network protocol, a personal area network protocol, a low-power digital radio protocol, and a hypertext transfer protocol.
5. The converter of claim 2 , wherein the first transceiver is a first UART with asynchronous input/output connected serially with a microtransceiver with auto shutdown, the second transceiver is a CAN transceiver, and the third transceiver is a low-power transceiver.
6. The converter of claim 5 , wherein the low-power transceiver transmits the serial output over a high-level communication protocol using small, low-power digital radios based on the IEEE 802.15.4 standard.
7. The converter of claim 1 , wherein the inputs are selected from a group consisting of an analog input, a digital input, a frequency input, modem data, or GPS data.
8. The converter of claim 1 , wherein the inputs are at least one analog input and at least one digital input.
9. The converter of claim 1 , further comprising a real-time clock for regulating the central processing unit and the inputs.
