Abstract
The utility model relates to a multifunctional matrix calculator which comprises a body. The body is provided with a display screen and a keyboard, the keyboard is a matrix keyboard and is composed of 16 keys which are arranged to be in a square array that four keys are in one row and four keys are in one line, the body is further provided with a light-emitting diode (LED) bulb, an alarm clock and a bulb switch, and a controller is arranged in the body. The multifunctional matrix calculator can not only be used for calculation of adding, subtracting, multiplying and dividing, but also has lighting and alarm clocking alarming functions and the like, and the multifunctional matrix calculator is convenient to use and simple in operation.
Description
Technical field
The counter that the utility model relates to, what be specifically related to is the multi-functional matrix counter.
Background technology
At present, counter has made things convenient for users' use as a kind of quick, general computational tool.Single-chip microcomputer is widely used in the fields such as household electrical appliance, Industry Control, financial management because of characteristics such as the little and cost of its volume are low.Existing counter comprises body, be provided with keyboard and display screen on the body, but above-mentioned calculator function is single, only possess computing function, when using night, compartment lamp need to be opened, otherwise do not see the button of counter, can not calculate, and the work of turning on light night can impact for other people in the room, affect that other people normally has a rest in the room; In addition, existing counter can not be reminded the user, makes people usually forget rest because being busy with work, and is unfavorable to health.
Summary of the invention
The purpose of this utility model provides the multi-functional matrix counter, and this multi-functional matrix counter is used for solving the existing single problem of calculator function.
The technical scheme that its technical matters that solves the utility model adopts is: this multi-functional matrix counter comprises body, be provided with display screen and keyboard on the body, keyboard is matrix keyboard, and keyboard is comprised of 16 buttons, and 16 buttons are lined up the square array of 4 buttons of the every row of 4 buttons of every row; Also be provided with LED bulb, quarter-bell, bulb switch on the body, be provided with controller in the body.
It is the single-chip microcomputer PLC of 89C51 that the such scheme middle controller adopts model.
Display screen adopts integrated 7 sections Liquid Crystal Module LCD1602 charactrons in the such scheme.
The utlity model has following beneficial effect:
The utility model not only can add, subtracts, the multiplication and division computing, also has the functions such as illumination and clock alarming, and is easy to use, simple to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the circuit diagram of quarter-bell in the utility model;
Fig. 3 is the cut-away view of keyboard in the utility model.
1 display screen 2LED bulb, 3 quarter-bells, 4 keyboards, 5 bulb switches, 6 bodies.
Embodiment
As shown in Figure 1, this multi-functional matrix counter comprises body 6, is provided with controller in the body 6, and it is the single-chip microcomputer PLC of 89C51 that controller adopts model, and single-chip microcomputer PLC is control core.Be provided with display screen 1 and keyboard 4 on the body 6, also be provided with LED bulb 2, quarter-bell 3, bulb switch 5 on the body 1.
Quarter-bell 3 is prompting parts of multi-functional matrix counter, and quarter-bell 3 adopts the special-purpose quarter-bell of common counter, and its Main Function is timely user's prompt function, and Fig. 2 provides the circuit diagram of quarter-bell.
Keyboard 4 is inputs of multi-functional matrix counter and part is set, keyboard 4 is matrix keyboards, it adopts four I/O lines as line, article four, the I/O line forms keyboard as alignment, in each point of crossing of line and alignment a button is set, the quantity of button just is 4 * 4=16 on the keyboard like this.As shown in Figure 3, it is comprised of 16 buttons, just in time has a P port to realize 16 keypress functions in single-chip microcomputer.Adopt matrix keyboard as input circuit, its characteristics: the transmission of data is fast, when number of keyboard keys is more, more saves the I/O mouth.The matrix keyboard that the utility model adopts is input value easily, makes operation interface have more hommization, has saved valuable I/O mouth resource.
Principle of work of the present utility model:
The user can be according to different requirements, utilize the multi-functional matrix counter to calculate, throw light on and remind operation.When calculating, open the counter switch, utilize keyboard 4 with budget data and sign of operation input counter, the result of calculation of data and unit of account will be presented on the counter display screen 1.When illumination, open LED bulb switch 5, make LED bulb 2 beginning illumination works, realize the illumination operation of multi-functional matrix counter.When utilizing the multi-functional matrix counter to remind, open the counter switch, utilize keyboard 4 that reminder time and prompting sound type are set.When counter count down to the corresponding time, the quarter-bell 3 of multi-functional matrix counter was started working, and realized the prompting function of multi-functional matrix counter.
