There are disadvantages in agricultural equipment testing systems, such as difficulties with wiring, limited transmission and the problematic expansion. Yet with embedded technology and virtual instruments, the development of various wireless transmission modes for agricultural equipment, which related to parameters measurement and control systems, improved the overall reliability. Embedded technology and virtual instruments addressed testing in the field, the single function of traditional testing instruments, the lack intelligent data processing, and so on. The core technology integrated intelligent agricultural equipment by using similarity parameters acquisition, and wireless transmission platform development, in addition to computer software platforms for receiving and handling wireless data transmission. The quality of agricultural equipment and automation level was effectively improved. 
