초록 ▼

A remote temperature sensing and warning system for a temperature controlled vehicle comprising a remote temperature sensing unit for measuring the temperature in the transport container and transmitting the temperature signal within a repeating time frame through the existing vehicle wiring to a remote receiver; the receiver decoding and converting the signal into a displayable form to continuously display the current temperature of the transport container; the receiver further detecting out of range temperatures and signal transmission errors and providing visual and aural alarms therefrom.

대표청구항 ▼

A remote temperature sensor and alarm system for a temperature controlled vehicle comprising: a. a fixed rate oscillator; b. means for sensing temperature said sensing means producing a temperature related electrical output; c. means producing an analog repeating ramp voltage time frame synchronous with said oscillator; d. a transmitter comparator receiving the output of the temperature sensing means as a first input and the analog ramp voltage as a second input said transmitter comparator producing a low output while the first input exceeds the second input and a high output while the second input exceeds the first input; e. a programmable divider receiving a first input from the oscillator and a second input from the transmit comparator said programmable divider producing an output of a first frequency while the second input is low and an output of a second frequency while the second input is high; f. a transmitter receiving the programmable divider output, said transmitter conditioning and transmitting said first and second frequencies; g. a receiver receiving said first and second frequencies; said receiver conditioning said frequencies for transmission therefrom; h. a processor unit receiving the said conditioned first and second frequencies from said receiver and decoding from each of the said transmitted time frames a temperature value; i. a means for displaying said temperature value received from said processor unit.
