Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail:
As shown in figure 1, a kind of for usb microwave power probe wireless extension device, include usb microwave power pop one's head in 8,
Usb interface 1, usb main mouth control module 2,8051 single-chip microcomputers 3, energy supply control module 4 and serial ports turn bluetooth module 5；Described
Usb microwave power probe 8 connects usb main mouth control module 2 by usb interface 1, has inside described usb main mouth control module 2
Usb control chip 10, described usb main mouth control module 2 is connected with 8051 single-chip microcomputers 3, and 8051 described single-chip microcomputers 3 are provided with string
Mouth turns bluetooth module 5.
Described usb interface 1 connects energy supply control module 4, and described energy supply control module 4 is lithium battery power supply.
As shown in Fig. 2 described usb control chip 10 adopts the cy7c68014a of cypress company.Described usb controls
Chip 10 is mated by the configuration data in reading eeprom read only memory 9 and identifies usb microwave power probe 8.
Usb interface 1 be configured to master mode, usb control chip 10 adopt both-end point fifo pattern, usb control chip
Cpu in 10 is not involved in data processing, sets up direct data channel 12 between usb interface 1 and 8051 single-chip microcomputers 3, improves
