Current Detection Circuit Temperature Compensation for Solenoid Valves

The patent applies parameter changes by introducing temperature compensation coefficients that adjust the detection characteristics based on temperature conditions. The correction unit changes the detection parameters (gain and offset) according to temperature, thereby maintaining high detection accuracy across different temperature ranges while ensuring reliable operation.

The patent implements feedback by using the temperature detection value to dynamically adjust the current detection characteristics. The correction unit receives temperature information and feeds back adjusted detection parameters to compensate for temperature-induced errors, thereby improving both accuracy and reliability simultaneously.

The patent applies preliminary action by pre-storing temperature compensation coefficients in the storage unit before actual current detection is needed. These coefficients are calculated in advance based on temperature characteristics, so when temperature correction is required, the system simply retrieves and applies the pre-computed values, avoiding complex real-time calculations and reducing circuit complexity.

The patent segments the temperature compensation process into distinct functional units: temperature sensor, storage unit for coefficients, and correction unit. This segmentation allows each component to perform a specific function efficiently, simplifying the overall design while achieving accurate temperature compensation across different operating conditions.

The patent applies self-service by having the system automatically measure its own temperature and apply the appropriate compensation coefficients without external intervention. The temperature sensor monitors the actual operating temperature, and the correction unit automatically adjusts the detection characteristics, enabling the system to self-correct for temperature variations and reducing the need for high manufacturing precision.

The patent uses parameter changes to compensate for manufacturing variations. By storing multiple compensation coefficients corresponding to different temperature conditions and selecting the appropriate coefficient based on actual temperature, the system can accommodate normal manufacturing tolerances while maintaining high detection accuracy across the operating temperature range.
