Abstract
The utility model is applicable to the field of electric energy metering, and provides an electric energy meter. The electric energy meter comprises a microcontroller and a push-button module which isconnected with the microcontroller, wherein the push-button module further consists of a sensor and a touch induction module which can convert signals sensed by the sensor into digital signals and outputs the digital signals to the microcontroller. The electric energy meter provided by the utility model has excellent waterproof and dustproof effects, strong interference resistance and long service life through adopting touch push-buttons.
Description
Technical field
The utility model belongs to the electric energy metrical field, relates in particular to electric energy meter.
Background technology
Electric energy meter is the clearing foundation of " " this specialty goods as measuring products, needs non-stop run 24 hours every days, and complicated industrial environment has been aggravated the requirement to the ammeter reliability especially.
Present electronic electric energy meter all is to adopt the mechanical type button, particularly does as one wishesly not to the utmost at aspects such as waterproof and dustproofs, is difficult to guarantee the reliability of ammeter long-time running.
The utility model content
The purpose of this utility model is to provide a kind of electric energy meter, is intended to solve existing electric energy meter and adopts the mechanical type button to cause the waterproof and dustproof effect bad, and anti-interference is not strong, the problem that button comes off easily and serviceable life is short.
The utility model is achieved in that a kind of electric energy meter, comprises microcontroller, and described electric energy meter also comprises the key-press module that is connected with described microcontroller; Described key-press module further comprises:
Sensor; And
With the conversion of signals of described sensor sensing is digital signal and the touch sensible module of exporting to described microcontroller.
The electric energy meter that the utility model embodiment provides adopts touch-key to make that the electric energy meter waterproof and dustproof is effective, strong interference immunity, button never drop-off and long service life.
Description of drawings
Fig. 1 is the structural drawing of the electric energy meter that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The electric energy meter that the utility model embodiment provides adopts touch-key to make that the electric energy meter waterproof and dustproof is effective, strong interference immunity, and long service life.
Fig. 1 shows the structure of the electric energy meter that the utility model embodiment provides, and for convenience of explanation, only shows the part relevant with the utility model embodiment, and details are as follows.
Electric energy meter comprises: key-press module 1 and microcontroller 2, and key-press module 1 is connected with microcontroller 2; Wherein, key-press module 1 further comprises: sensor 11 and touch sensible module 12; Touch sensible module 12 is digital signal and exports to microcontroller 2 conversion of signals of sensor 11 inductions.
As an embodiment of the present utility model, sensor 11 can be spring, also can be conductive sponge, can also have the components and parts of induced signal function for other are any; Touch sensible module 12 is that (Programmable System On Chip PSoC), can be capacitive sensing chip or resistance induction chip to a kind of programmable system level chip; The capacitive sensing chip comprises a capacitance switch, and capacitance switch is a pair of adjacent electrode, and very little electric capacity is arranged between electrode; When a conductor during, between electrode and conductor, can produce a coupling capacitance near two electrodes; Finger is exactly this conductor, and the form of capacitance switch is the electric capacity of one side ground connection usually, and the existence of conductor has increased switch to the electric capacity between the ground; Whether have finger close, whether have button press, can judge according to changes in capacitance if just detecting if detecting.Simultaneously, spring is equipped with in electric energy meter watchcase inside, and when finger touches the local time of spring induction, whether the capacitive sensing chip recognizes by changes in capacitance has key to press.
The design of traditional mechanical type button always has the space, so that the chance of entry is arranged, and makes control panel malfunctioning, the electric energy meter that the utility model embodiment provides adopts the touch-induction-type button, the incorporate panel that does not have the space, cleaning is really accomplished waterproof and dustproof easily; Simultaneously, anti-interference is extremely strong; The permanent reliably working of membrane keyboard does not have mechanical key problem in serviceable life; In addition, the size of touch-induction-type button or quantity are not limited by mould, and layout depends on the design of pcb board fully, and promptly same mould can have different key arrangements because of the design of pcb board.
The electric energy meter that the utility model embodiment provides adopts touch-key to make that the electric energy meter waterproof and dustproof is effective, strong interference immunity, button never drop-off and long service life.Simultaneously, touch-key has reduced the structure assembling procedure that brings because of mechanical key, adopts the touch of hommization, can not experience the ravage of mechanical key to user's finger.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
