It is featured as connecting Bluetooth module chip to CPU of T1 pattern calculator through differential signal and using control unit to receive or emit radio communication signal. The radio teaching network structured by said calculator comprises teaching computer based on Bluetooth technique and T1 pattern calculator with Bluetooth controller.

Description

technical field [0001] The invention relates to a T1 graphic calculator and a wireless teaching network, in particular to a wireless teaching network applied to the T1 graphic calculator. Background technique [0002] The existing wireless teaching network of TI graphing calculator adopts a solution based on WLAN (wireless local area network) (IEEE802.11b), but the current WLAN solution needs to use HUB, so the cost is relatively high, and the required HUB The TI graphing calculator on the terminal needs to be connected with a cable, so the mobile TI graphing calculator is less portable and consumes more power. Although it has the advantages of fast transmission speed and long transmission distance, as far as the actual classroom teaching environment is concerned, such high transmission distance and transmission speed are generally not required. Contents of the invention [0003] The invention provides a T1 graphic calculator and a wireless teaching network constructed us...
