Description

technical field

[0001] The invention relates to the technical field of network and communication, in particular to a CAN bus communication method and structure. Background technique

[0002] The automatic coagulation analyzer includes a blood sample delivery module, a reagent position management module, a test cup delivery module, a detection module, a three-dimensional motion module, and a gas-liquid circuit module. The main function of the communication system is to connect each module to form a communication network, combined with the mechanical structure, and send different command combinations through the PC to realize the entire workflow control and monitoring of the coagulation analyzer. With the continuous improvement of the automation of the coagulation analyzer, a large amount of data needs to be exchanged and processed between various modules during the working process, so the performance of the communication system directly affects the working efficiency of the c...
