Description

From the international paging code code generator of programming

The utility model belongs to technical field of information processing, relates to a kind of from the international paging code code generator of programming.

At present, all kinds of code generators that are widely used in (as communication, electronics etc.) in a lot of fields, owing to need be equipped with special receiver in use, and shortcomings such as the ubiquity volume is big, cost height, and code capacity is little, and error correcting capability is poor.And an existing international paging code code generator though can overcome some above-mentioned shortcomings, owing to can't need be equipped with PC during use from programming, still have shortcomings such as volume is big, cost height, and function is fairly simple.

The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of from the international paging code code generator of programming.

Certainly the international paging code code generator of programming provided by the utility model is by single-chip microcomputer IC ₁, memory IC ₂, composition such as input circuit, display circuit, power supply, electronic switching circuit, wherein:

Input circuit is by button AN, resistance R ₄, dial B ₁Form button AN one terminating resistor R ₄With IC ₁Tie point, other end ground connection, resistance R ₄Another termination battery BAT positive pole.

Display circuit is by light-emitting diode L ₁, resistance R ₃, capacitor C ₃And Microspeaker SP forms.

Power supply is by battery BAT, capacitor C ₄-C ₇, diode D ₁And integrated regulator IC ₃Form capacitor C ₄, C ₅BAT is connected in parallel on IC with battery ₃Between the output and ground, capacitor C ₆, C ₇Be connected in parallel on IC ₃Between input and the earth terminal, diode D ₁Be connected on positive supply input A and IC ₃Between the input.

Electronic switching circuit is by triode N ₂, N ₃, biasing R ₈, R ₉, capacitor C ₈Form, its input passes through resistance R ₁₀With IC ₁The coding output link to each other, its output neither one is by capacitor C ₉, C ₁₀, the filter network that inductance L is formed.

IC of the present utility model ₁With R ₅Between neither one vibrating sensor interface G, resistance R ₅The other end links to each other with battery BAT is anodal.

To reach embodiment with reference to the accompanying drawings below is described in further detail the utility model.

Fig. 1 is circuit theory diagrams of the present utility model.

Among the figure: A is a 5-30V positive supply input; B is a ground wire; C is the coding output; D is system's Enable Pin; E is a 5V rechargeable battery link; F is a power output end; G vibrating sensor interface.

According to Fig. 1, IC₁Adopt the PIC16 series monolithic; IC₂Adopting model is the EEPROM of 24LCo2; It consists of the memory system of code generator. Four driver plate B in the input circuit₁With IC₁The 6-9 pin link to each other successively, button AN is connected on IC₁17 pin and ground wire between, resistance R₄Be connected on battery BAT positive pole and IC₁17 pin between, under programming state, the user can be by AN and B₁Input needs the information code (such as paging information, address code, bit rate etc.) of transmission, and in operating process, system is by the light emitting diode L in the display circuit₁With Microspeaker SP indication and feedback states information, the information of input is through single-chip microcomputer IC₁The international paging code code of generation standard is preserved after the computing, and passes through in due course 13 pin through resistance R₁₁Carry Export to transmitter. IC₁13 pin in code output, send preamble to open by triode N₂、N ₃Deng the on-off circuit that forms, to the external equipment that is connected to power output end F (such as transmitter, information ring Device etc.) power supply. 5-30V positive supply input A is through resistance R, diode D₁With integrated regulator IC₃Provide the floating charging electric current to battery BAT, the E line connects the 5V charging current simultaneously, so that back-up source to be provided. IC₁5 pin and the resistance R between 18 pin₁₂, the contact between the R13 is the Enable Pin D of system, when the D line is in height Forbid alert program during level, and when the D line unsettled or when being pulled to low level code generator enter the timing journey Order after time-delay, enables warning system and enters the state of alert. IC₁10 pin be vibrating sensor interface G, Can not start alert program during G line level equalization, when system enables the outside incoming level saltus step of rear G line Just can start alert program. IC₁11 pin and ground wire between be serially connected with resistance R₆、R ₇, its minute pressure side and diode D₁Positive pole joins, and when the positive supply that is connected to the A line is destroyed, can start immediately alert program.

According to the effect of above A-G line, the utility model can form multiple wireless with the existing beeper of user Electric alarm, burglary-resisting system, as: house safety defence system, ward emergencycallboxsystem, motor vehicles Burglar alarms etc. also can form beeper maintenance testing equipment with the variable frequency transmitter.

Application example: the positive supply input A and the motorcycle battery electrode of code generator are joined, the E point connects the 5V rechargeable battery, the G line directly articulates vibrating sensor, the D line connects motorcycle electric switch rear end, the C line connects the signal input part of HF transmitter, F line and the power supply of B alignment HF transmitter can constitute a motorcycle anti-theft alarm.After the motorcycle electric switch cuts out, the D line is a low level, make code generator enter timing program, after delaying time, (allow the car owner that the motorcycle that comes to a complete stop of enough time is arranged) and enter the state of alert, monitoring motorcycle, move car if any the people and will trigger alert program this moment, and by HF transmitter information is mail to car owner's beep-pager, and the car owner can know the situation of motorcycle according to the beeper of carrying like this.Because the detection of power loss function of code generator can start alert program immediately when having the people to attempt to remove or destroying alarm.

The utlity model has that cost is low, volume is little, code capacity is big, error correcting capability is strong, stable performance Etc. advantage.
