Abstract: A cutting fluid digital monitoring and management system and method are provided, applicable to a computer numerical control (CNC) machining device. The CNC machining device has a cutting fluid tank configured to accommodate a cutting fluid. The cutting fluid digital monitoring and management system includes: a detection tank, configured to extract a cutting fluid from the cutting fluid tank through a motor and an electrically controlled water valve; a concentration sensing module, a pH sensing module, a water hardness sensing module, and a temperature sensing module, respectively configured to obtain a concentration, a pH value, a hardness, and a temperature of the cutting fluid; a processing module, configured to generate a monitoring integration value, compare the monitoring integration value with a standard model, and generate an adjustment signal; and an adjustment module, configured to actively adjust a variable parameter of the cutting fluid according to the adjustment signal.

Abstract: A data packet processing method comprises: receiving data packet including a key message; analyzing the key message; determining whether the data packet is a high priority data packet or a normal data packet according to a result of analyzing the first key message of the data packet; and executing an Rx high priority interrupt in response to determining that the data packet is the high priority data packet. The Rx high priority interrupt is to immediately transmit an interrupt signal to interrupt receiving of the data packets.
