Authorization Notice No. is: the utility model patent of CN 2735885 Y proposes a kind of Inductive mail box, comprises inductor, optoelectronic induction processing controller, optoelectronic induction processing controller probe, LED signal lamp.Adopting household electric or solar cell with rechargeable battery powered, dropping into by being arranged on mailbox delivery port optoelectronic induction processing controller probe detection with or without mail, when realization has a mail, LED signal lamp lights, reminding user pickup.
Authorization Notice No. is: the utility model patent of CN201939066 U proposes a kind of mailbox having function of warning letter incoming, comprise the gravity sensor, the main control chip that are arranged on bottom half, and be arranged on the bulb of mailbox outside, gravity sensor receives outer signals, and it is converted into digital signal transfers to main control chip, main control chip transmits control signal to bulb circuit after receiving signal, the control signal that bulb circuit sends according to the main control chip received, control bulb light on and off, realize letter prompting function.
Existing mailbox letter alarm set, major part determines whether mail by gravity sensing or optoelectronic induction, but all lack the quantitative statistics of mail number, and user does not know the mail number deposited in mailbox.For the discipline inspection department that those need the user of quantitative Treatment mail and needs record often to seal the time of delivery of offence reporting letter, existing mailbox can not meet the demands.In such cases, design a kind of existing letter prompting function, the mailbox having counting and record mail time of delivery function concurrently just shows highly significant.
Summary of the invention
The object of the invention is to solve the problem, providing a kind of mailbox letter alarm set.
For achieving the above object, the method that the present invention adopts is: a kind of mailbox letter alarm set, comprise mailbox body, mailbox body upper end is provided with mailbox entrance, the mailbox body of mailbox entrance lower end is provided with infrared transmitter and infrared remote receiver, infrared transmitter and infrared remote receiver are separately positioned on the both sides of mailbox body, this device also comprises power supply module, MCU control module, letter indicator lamp, display module, wherein infrared infrared remote receiver is connected with MCU control module output pulse signal, power supply module and MCU control module phase vicinal system power supply, MCU control module is connected with letter indicator lamp, export letter cue, MCU control module is connected with display module, display mail quantity.
Improve as one of the present utility model, described mailbox is also provided with a reset button, and described reset button is connected with described MCU control module.
Improve as one of the present utility model, described MCU control module adopts MSP430F149 single-chip microcomputer.
Improve as one of the present utility model, described power supply module adopts the button cell of 3V.
Beneficial effect:
The utility model structure is simple, easy to use, when there being mail to deliver, the bright mail number simultaneously recording delivery of indicator lamp, and record the time of delivery of every part of mail, user can to check in mailbox the time of delivery of existing how many envelope letter and every envelope letter without the need to opening mailbox.The utility model adopts chip that is cheap, low-power consumption in addition, and main chip is power consumption hardly in stand-by mode, farthest extends the service life of battery.When the power supply adopting 3V button cell as this device, this device can continuous operation about month, practical.
Accompanying drawing explanation
?fig. 1 is mailbox structure schematic diagram.
Fig. 2 is software flow figure.
Fig. 3 is mailbox letter alarm set hardware theory of constitution block diagram.
Each parts in figure are: 1 mail, 2 mailbox entrances, 3 infrared transmitters, 4 infrared remote receivers, 5 circuit boards and display module part.
Detailed description of the invention
Below with reference to specific embodiment, the technical scheme that the utility model provides is described in detail, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Fig. 1 is mailbox structure schematic diagram of the present utility model, comprise mailbox body, mailbox body upper end is provided with mailbox entrance 2, the mailbox body of mailbox entrance 2 lower end is provided with infrared transmitter 3 and infrared remote receiver 4, and infrared transmitter 3 and infrared remote receiver 4 are separately positioned on the both sides of mailbox body.Mailbox body is also provided with circuit board and display module part 5.
Circuit board and display module part 5 comprise power supply module, MCU control module, letter indicator lamp, display module as shown in Figure 3, wherein infrared infrared remote receiver 4 is connected with MCU control module output pulse signal, power supply module and MCU control module phase vicinal system power supply, MCU control module is connected with letter indicator lamp, export letter cue, MCU control module is connected with display module, display mail quantity.
MCU control module of the present utility model adopts low-power consumption MSP430F149 as controller, power supply module adopts 3V button cell and provides power supply by the various piece that power-switching circuit is this device, wherein MSP430F149 uses the dc source of+3V, and display module adopts LCD liquid crystal display screen.Each components and parts are selected as follows in the present embodiment:
Battery: button cell, brand or model: CLN/CR2477, normal voltage: 3V, rated capacity: 1100mAh.
MSP430F149: working power voltage: 1.8 V to 3.6 V, normal mode of operation 280 μ A@1MHz, 2.2V, standby mode 1.6 μ A, 0.1 μ A, 2K RAM, 60K+256B Flash Memory under the power-down mode that RAM data are preserved.
LCD liquid crystal: Changsha sun people, SMS1005, module work voltage: 1.4 ~ 1.6V module optimum operating voltage: 1.5V, operating current: 15 μ A (1.5V) backlight operating voltage: 3V(40mA, can external resistor regulate).
