Abstract
The utility model relates to a computer scale for filling liquified gas, which is composed of an explosion-proof instrument box, a microcomputer system, a weighing platform, a displayer, etc. A weight sensor is installed in the weighing platform. The weight sensor transmits weighing signals to the microcomputer system in the instrument box. A peeling starting button, a filling quantity setting device, and the setting device of an advanced valve-off quantity are also arranged on the instrument box. The utility model has the advantages of accurate measurement and convenient operation. The computer scale for filling liquified gas not only solves the problems of the mechanical filling scale of complicated structure, big reading errors, and many troubles at operation aspects, but also solves the problem that a common computer scale is easy to generate reading errors.
Description
The utility model relates to a kind of metering outfit, particularly a kind of liquefied gas computer can scale with microcomputer system control.
At present, the various liquefied gas auto-filling scales of domestic production and use, mainly be divided into two classes, one class is a mechanical type, it is provided with peeling heavy-duty machine structure and quantitative mechanism, rely on the metering scale to finish the function that peeling heavily reaches quantitative filling, the weight transfer system that (as ZL91222427.4) this class scale adopts multi-grade lever to form, and by arm beam of steelyard scale or dial plate pointer demonstration gravimetric value.Its measuring accuracy is low, speed is slow, and show not directly perceived, dial plate beat of pointer amplitude is bigger, bigger when carrying out weighing continuously to the precision influence, and all need to claim the weight of empty bottle before each can, use peeling scale and peeling thallium to remove tare weight, weighing speed is low, can not satisfy the requirement of city gas bottling quantity-produced.Second class is the automatic control scale based on the common computer scale.Existing technology (as ZL88211511.1) is according to the pouring process of controlling liquefied gas for accept dynamic scan numeral font with microcomputer system, its shortcoming is that microcomputer system obtains data to accept this indirect mode of dynamic scan numeral font signal, might cause microcomputer system to obtain error in data because of the fault of display system, and influence the degree of accuracy of can.
The purpose of this utility model provides a kind of novel liquefied gas computer can scale, it can overcome mechanical type can scale complex structure, the dial plate beat of pointer is big, influence measuring accuracy, and troublesome poeration, and that the common computer scale is accepted dynamic scan numeral font signal accuracy is poor, and shortcoming such as easily make a mistake.
The technical solution of the utility model is as follows: liquefied gas computer can scale, comprise instrument box, microcomputer system, weighing unit, display, it is characterized in that: the inner installing of weighing unit (a 2) LOAD CELLS (201), the signal wire connecting of LOAD CELLS (201) is on the special purpose interface on the instrument box (1); Microcomputer system (101) is equipped with in instrument box (1) inside, peeling is housed on the panel of instrument box (1) starts button (102), can variable setting apparatus (103), close valve variable setting apparatus (104) and nixie display (105) in advance; The signal wire interface circuit is connected to analog to digital converter (113) through amplifier (116), analog to digital converter (113) links to each other with the P1 mouth of single card microcomputer (111), the P0 mouth of single card microcomputer (111) is connected with charactron dial switch control chip (115), charactron dial switch control chip (115) data output end is connected with nixie display (105), can variable setting apparatus (103) with close valve variable setting apparatus (104) in advance and be connected with charactron dial switch control chip (115), single card microcomputer (111) P0 mouth is connected to program storage (112), the output of program storage (112) data is connected to the P2 mouth of single card microcomputer (111), and the T of single card microcomputer (111) * D end is connected to the control end of solenoid valve (5) through relay (114).
The utlity model has following advantage and effect: using by microcomputer system is that the electronic scales of core is controlled whole pouring process, the weight data that microcomputer system obtained directly obtains from LOAD CELLS, degree of accuracy is greatly improved, and do not need artificial peeling heavy, only need push a key and just can finish peeling automatically and heavily reach the can overall process by microcomputer system; Adopt and close threshold value setting in advance, improved filling accuracy.
The drawing of accompanying drawing is described as follows:
Fig. 1, liquefied gas computer can scale structural representation.
Fig. 2, the microcomputer system circuit diagram.
Be described further below in conjunction with drawings and Examples:
See also Fig. 1 and Fig. 2,, have the function of weigh and demonstration weight by the ordinary electronic scale that microcomputer system (101) is formed; The input port of microcomputer system (101) and can variable setting apparatus (103) and close valve variable setting apparatus (104) in advance and link to each other.Microcomputer system (101) is respectively from can variable setting apparatus (103) and close valve variable setting apparatus (104) in advance and read in the quantitative filling gravimetric value and close threshold values in advance, the difference that this two value is subtracted each other is closed the gravimetric value of valve as reality, deposit in the microcomputer system (101), microcomputer system (101) controlling and driving solenoid valve (5) opens or closes to realize the switch control to the liquefied gas stream, the middle fracture of microcomputer system (101) starts button (102) with peeling and links to each other, after microcomputer system (101) detects peeling and starts button (102) and be depressed, just immediately current gravimetric value of weighing is delivered in the tare weight register in the microcomputer system (101), the value of weighing later on all deducts the tare weight value, send nixie display (105) with difference, shown gravimetric value is the net weight value that pours into liquefied gas in the steel cylinder, after having preserved the tare weight value, microcomputer system (101) control electromagnetic valve (5) is opened, can liquefied gas in steel cylinder.When the weight that detects the liquefied gas that charges into when microcomputer system (101) reaches actual pass valve gravimetric value, then solenoid valve (5) is turn-offed in control, after liquefied gas falls into steel cylinder fully, the can that the weight of liquefied gas and can variable setting apparatus (103) set in the steel cylinder is equal in weight, and reaches the purpose of quantitative filling.
