[Detailed ways]

Referring to Figures 1-5, an intelligent power-saving infrared split display electronic scale includes a scale body 1 and a hand-held display 2 set separately from the scale body 1. The scale body 1 includes a central controller 3 and is used for weighing The weighing module 5 of object weight is connected with the automatic frequency conversion detection module 31 that is used for frequency conversion detection weighing module 5 weighing data between central controller 3 and weighing module 5, and described central controller 3 is also connected with When the weighing module 5 weighs and reaches the set value, send the infrared transmitting module 6 of the control signal and the data signal, and the handheld display 2 includes an infrared receiving module 8 for receiving the infrared transmitting module 6 signal, on the infrared receiving module 8 It is connected with a terminal controller 7 that controls the closing of the infrared receiving module 8 after not receiving the signal of the infrared transmitting module 6 within a certain period of time, and the terminal controller 7 is connected with a display 9 for displaying weighing data. the

The weighing module 5 includes a load cell 51 , an amplification and filtering circuit 52 , and an A/D conversion circuit 53 connected in sequence. the

The central controller 3 is also connected with a power management module 32 and a data processing module 35 for weighing data unit conversion, and an infrared emission control module 33 is connected between the central controller 3 and the infrared emission module 6 . the
