CONTROL OVER SPACECRAFT HARDWARE HEATERS Russian patent published in 2015 - IPC G05D23/19 

FIELD: aircraft engineering.

SUBSTANCE: claimed control device comprises the following components interconnected via internal trunk: microprocessor, RAM with digital data output ports, ROM and discrete data receiver port. ROM stores software of temperature setting for every setting and operation of the entire device. New operating parameters are incorporated therewith, that is, ADC, digital comparator and info interface module, to maintain the preset temperature of every electric heater. This is based on a continuous tracing of spacecraft every element actual temperature and generation of pulse signal to control the heating of said element at preset measuring cycle frequency written in ROM. This allows a stable operation of the control device with n-m number of electric heaters for objects that required the maintenance of different operating temperatures. Besides, it provides for a high validity of telemetry and control over the device operating conditions.

EFFECT: high stability and accuracy of temperatures, higher reliability.
