Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
With reference to Fig. 1, Fig. 3 and Fig. 4, an instance of gas-jar scale of the present invention is proposed, comprise the scale body, be used to place the gas-jar carriage of gas-jar, this scale body comprises a cup dolly and power supply 50, on the scale body, also is provided with the guidance panel 40 of button.This gas-jar scale also comprises:
(1) pressure transducer 10, can produce deformation according to ballast, and resistance changes after the deformation, can be in real time, accurately detect the general assembly (TW) electric signal of gas-jar and coal gas, and with detected general assembly (TW) electric signal output.
(2) main control module 20, are used for regularly detecting said general assembly (TW) electric signal, analyze the general assembly (TW) data that draw gas-jar and coal gas, and the weight of removing gas-jar again obtains coal gas weight data and output; This main control module 20 is a single-chip microcomputer, and single-chip processor i/o mouth state is different, and the display result of corresponding output also corresponding variation can take place.
(3) display module 30, are LED or LCD display, are used for going out said coal gas weight data through numeral or graphic presentation.
Button on the guidance panel 40 has start key, reset key and peeling key, is used for the level state of control single chip computer I/O mouth.The start key is used to control the switching on and shutting down of gas-jar scale, and the peeling key is used to circulate and switches the net weight state of coal gas, takes off behind the gas-jar by reset key, and the gas-jar weighing is newly resetted.Press key on time, single-chip processor i/o is put low level.Display module 30 is exported the relevant detection result according to the change of single-chip processor i/o mouth level state, and on display screen, shows the relevant detection result.
Press the start key, after the gas-jar scale is opened, under scale body no-load condition, press reset key, make the intrasystem digital zero clearing of gas-jar scale, reset again, in order to avoid occurrence of errors during weighing.Then; Put and be full of the bottle coal gas cylinder, pressure transducer 10 can produce deformation according to ballast, and resistance changes after the deformation; Produce the general assembly (TW) electric signal of this gas-jar and coal gas; I/O through single-chip microcomputer is input to single-chip microcomputer inside with the general assembly (TW) electric signal and analyzes again, draws the general assembly (TW) data of gas-jar and coal gas, and intuitively weight information is shown through LED or LCD display.Then press the peeling key, handle, obtain the coal gas weight data and on display screen, show by the weight that single-chip microcomputer is removed gas-jar to general assembly (TW).Also show coal gas surplus prompt on the display screen simultaneously, when the coal gas service wear, weight and coal gas surplus prompt can change accordingly, make things convenient for user real time to understand the surplus of coal gas.When pressing the peeling key once more, only show the general assembly (TW) data of gas-jar and coal gas on the display screen, continue to press the peeling key, just recover the weight data and the coal gas surplus prompt of coal gas on the display screen again.When the coal gas weight data that shows on the display screen is 0.0kg or when being lower than preset data value, coal gas surplus prompt is empty, the gas-jar scale can send alerting signal, reminds the coal gas in user's gas-jar to use up, and needs to change gas-jar; When the weight instantaneous variation on no button operation and the display screen was no more than 0.2kg, the scale body just can shut down after after a while automatically.When coal gas after using after a while, as wonder and still remain how much coal gas, then by the start key, switch through the peeling key, check current coal gas weight and coal gas surplus prompt.
With reference to Fig. 2, an instance of the measuring method of gas-jar scale of the present invention is proposed, may further comprise the steps:
Step S100, will detect the general assembly (TW) electric signal output of gas-jar and coal gas.
Step S200, timing detect said general assembly (TW) electric signal, analyze the general assembly (TW) data that draw gas-jar and coal gas, and the weight of removing gas-jar again obtains coal gas weight data and output.
Step S201, when detecting said coal gas weight data and not changing within a certain period of time, the shutdown of control gas-jar scale.
Step S202, when detecting the coal gas weight data and be lower than preset data value, send alerting signal.
Step S300, go out said coal gas weight data through numeral or graphic presentation.
The present invention can measure the weight of coal gas in the gas-jar, and can go out the data of said coal gas weight through numeral or graphic presentation, makes things convenient for user real time to understand the surplus of coal gas.
The above is merely the preferred embodiments of the present invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
