Title:
2.4GHZ WIRELESS CODE TABLE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/058504
Kind Code:
A1
Abstract:
A 2.4GHz wireless code table circuit, comprising a pulse detection transmitting circuit and a receiving display circuit, wherein the pulse detection transmitting circuit comprises a power supply circuit (110), a first low-voltage reset circuit (111), a pulse detection circuit and a 2.4GHz wireless transmitting circuit; the 2.4GHz wireless transmitting circuit comprises a ninth 2.4G wireless transceiving chip (U9) and a first antenna matching circuit (112); a pulse detection interrupt pin (P10) of the ninth 2.4G wireless transceiving chip (U9) is grounded via a reed switch (G1); when a magnet is within a detection distance range of the reed switch (G1), the interior of the reed switch (G1) is conducted, and when the magnet is outside the detection distance range of the reed switch (G1), the interior of the reed switch (G1) is an open circuit; a timer is embedded in the ninth 2.4G wireless transceiving chip (U9); and when the timer overflows, the ninth 2.4G wireless transceiving chip (U9) sends the detected number of pulses to the receiving display circuit via the first antenna matching circuit (112). The 2.4GHz wireless code table circuit can reduce power consumption, enlarge a speed detection range, and improve the reliability of a wireless code table.
