Below in conjunction with accompanying drawing Help by Phone device of the present utility model is described further:

Fig. 1 is the circuit block diagram of the utility model A Help by Phone device.

Fig. 2 is the circuit theory schematic diagram of the utility model Help by Phone device.

As shown in Figure 1 and Figure 2, under the control of u2 CPU, the exchange line signal is imported from JK1, flow through behind the high voltage protective, output circuit is divided into two-way: one tunnel rectifier bridge that outputs to the clamp diode composition carries out polar switching, outputs to the ringing detection circuit then and carries out the ring detecting, bell signal is outputed to the interrupt interface INT1 of u2CPU, u2 CPU receives behind the bell signal to send to u3 by its P4 and opens high level command, makes u3 in running order; Circuit is adjusted by dtmf signal in another road, signal is outputed to the P1P2 input port of u3, after u3 receives signal, carry out the A/D analog-to-digital conversion, u2 CPU by its P3 after the P15 of u3 sends control command, u3 outputs to digital signal among the u2 CPU by data port Q1, Q4, u2 CPU outputs to LCD when showing with the digital signal that receives, the digital signal of input is stored in the RAM district of u2 CPU, finishes the work of received signal, displayed record, stored record.

Clock oscillation circuit links to each other with P12, the P13 of u2 CPU by oscillator, produces frequency of oscillation, links to each other with P74, the P75 of u2 CPU by the function vibration then, makes the function vibration produce the required work main oscillation frequency of u2 CPU.

Energy storage and power supply circuits, when+after the 9V environment-friendly battery carries out circuit protection by clamp diode D14, be divided into two-way output, the one tunnel outputs to accumulator, to its charging energy storage; Another road outputs to reduction voltage circuit, and general+9V becomes+5V, simultaneously, and to charge energy storage and of capacitor C 6 to the power supply of u2 CPU and entire circuit.Not enough or when changing battery when the power of battery, discharge by accumulator, capacitor C 6, guarantee the power supply of u2 CPU and entire circuit within a certain period of time, keep operate as normal and preserve the record that the RAM district of u2 CPU stores.When accumulator, capacitor C 6 discharge offs, the record of the RAM district of u2 CPU storage will disappear.

When the low level test circuit test power of battery was not enough, weak electric signal outputed to the P2 of u2 CPU, and u2 CPU outputs to the light current marking signal on the LCD, carried out light current and showed that the prompting user changes battery.

When the record in the RAM district of needs inquiries or deletion u2 CPU, utilize external key " History ", " DOwn ", " uP ", " Remove " to send middle fracture INT0 from interruptive command to u2 CPU, P29.When pressing " Remove ", send querying command to the middle fracture INT0 of u2 CPU, press the record that " uP " or " Down " just can inquire about u2 CPU RAM district up and down; When pressing " History ", fracture INT0 sends delete command in u2CPU, and u2 CPU will start reset circuit, finish delete function.
