Specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

Referring to figs. 1 to Fig. 8, the utility model provides a kind of 433M wireless signal and changes hands machine short message apparatus, including shell, shell Intracorporal PCB circuit board 4 and key 5, the PCB circuit board 4 include power module, lithium battery module, high-decibel buzzer, GPRS module, single-chip microcontroller, RF wireless module, the power module, lithium battery module, high-decibel buzzer are electrically connected to each other, institute It states GPRS module, single-chip microcontroller, RF wireless module to be electrically connected with lithium battery module, the GPRS module, RF wireless module, high score Shellfish buzzer, key 5 with monolithic mechatronics.

The single-chip microcontroller selects model STM8S005K6.

The high-decibel buzzer drives work by buzzer drive circuit, and the buzzer drive circuit uses three feet Boost inductance and triode Q1 drive high-decibel buzzer to boost.

The single-chip microcontroller drives buzzer drive circuit by the PWM wave generated.

The GPRS module includes GPRS chip and its peripheral circuit, and the GPRS chip connects SIM card holder, and uses serial ports Communicate to connect single-chip microcontroller.

The power module includes that charging chip SD8055 passes through charging chip when power module external power supply SD8055 charges to lithium battery.

The voltage of the lithium battery module is powered by voltage stabilizing chip HT7333 pressure stabilizing to single-chip microcontroller.

The key 5 includes switching circuit, and the switching circuit is controlled jointly by triode Q5, field-effect tube and single-chip microcontroller Startup and shutdown processed.

The shell includes shell 6 in shell 2, second in be fixed on pcb board two sides first, for the steel mesh 1 of heat dissipation, and For the shell 8, bottom cover 3 and rear cover 7 of encapsulating housing, an opening is equipped with before the shell 8, the steel mesh 1 is set to opening.
