Abstract

The invention relates to a control method of an electronic scale, which is implemented according to the following steps: customers place a product to be weighed onto a scale pan; signal wires that are connected with four sensors on four corners under the scale pan centralize analog weighing signals that are measured and transmit the signals to an A/D module; the A/D module converts the analog signals into digital signals, and a mainboard computes and processes the weights, and further sends the weights onto a main display and a customer display; the mainboard prints a price tag of the weighted product through an LPT communication interface after receiving a command that is sent out; an operator uses a scanner that is externally connected by a USB/RS232 port to scan barcodes of unpaid products one by one; data is transmitted to the mainboard through the signal wires; the mainboard computes and processes the data through foreground software, and further sends the data onto the main display and the customer display; when summing and bill settling are required, the operator can operate through a touch screen or a keyboard that is externally connected with a PS/2 port; the data stored in a hard disk is called by foreground processing, and the required data is printed through the LPT communication interface.

Description

The control method of electronic scales

Technical field

The present invention relates to a kind of electronic scales, relate in particular to a kind of control method of electronic scales.

Background technology

Electronic scales be a kind of integrate weigh, the electronic scales of printing, POS system.Be mainly used in supermarket, the hypermarket; The article that client weighs needs are placed on the scale pan of this electronic scales, and this scale prints corresponding price tag or receipt; And POS system can be passed through in supermarket or sales field, utilizes scanner reading tag and bar code and utilizes other specialized equipment to write down the income of this point of sale.

In some large-scale sales fields or supermarket, the use of electronic scales all is to locate to be provided with some electronic scaless free of variety classes commodity usually, treat that weighing is printed after, unify cash register to cashier.Along with expanding economy, medium and small chain store is more and more, concerning these shops, if still adopt metering earlier, print little of individual event, and then, first the client is brought inconvenience to cashier scanning cash register, second concerning businessman, two equipment had not only taken originally with regard to little space but also had brought the management trouble of manpower and materials.

The formation of these problems all is because the control module function singleness that adopts in the existing equipment causes.How utilizing the control module of prior art to design a kind of control method is the problem that the technician will solve.

Summary of the invention

The technical issues that need to address of the present invention have provided the control method in a kind of electronic scales, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the present invention realizes by following steps:

The commodity that client weighs needs are placed on the scale pan;

Connect the signal wire that by four sensors on following four angles of the scale pan and weigh the simulating signal concentration of transmissions to what record to A/D;

By A/D simulating signal is changed into digital signal and weight is sent to main apparent and objective showing by the mainboard computing;

Mainboard receives the price tag that prints the commodity of weighing after the instruction of sending again by the communication interface of LPT;

Operating personnel pass through the external scanner of USB/RS232 to the commodity of needs payment bar code one one scan of commodity;

Data arrive mainboard by signal wire transmits;

Mainboard carries out computing by foreground software to data again and sends to main apparent and objective showing;

Do not have the commodity of bar code to operate intuitively for some, also can carry out function operations such as subtotal by the preset key function on the touch-screen; Mainboard prints the receipt of all commodity again by the communication interface of LPT simultaneously;

When needing statistics to check out, operating personnel can operate by touch-screen or the external keyboard of PS/2;

Processing by the foreground is being stored in that data in the hard disk access and communication interface by LPT prints the data that need.

Compared with prior art, the invention has the beneficial effects as follows: can be on an electronic scales realize simultaneously weighing, the function of printing, cash register, be Yi Taiji weigh and POS system in the multifunction electronic scale of one, make some middle-size and small-size chain stores that bigger space be arranged; The expense of many electronic scaless is purchased in saving; Alleviate the management on the man power and material; Can also increase work efficiency effectively, shorten the time that client waits.

Description of drawings

Fig. 1 is a module map among the present invention;

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

This equipment be Yi Taiji weigh and POS system in the multifunction electronic scale of one, the present invention is a kind of improvement to the electronic scales control method, realizes host and guest's demonstration, touch screen operation, prints, weighs, function such as cash register.

As seen from Figure 1, whole module 10 comprise main show 1, the visitor shows 2, touch-screen 3, printer 4, primary power 5, hard disk 6, audio amplifier 7, case fan 8 and internal memory 9.Main apparent 1 is to realize Presentation Function by communication port 101 and the LVDS/TTL mouth 102 on the mainboard 10; It is to realize Presentation Function by communication port 201 and the com interface 202 on the mainboard 10 that the visitor shows 2; Touch-screen 3 is to link to each other with USB interface 302 on the mainboard 10 by the interface on the touch-screen control panel 31 301 to realize the work of touch keyboard part; Printer 4 can be connected with corresponding LPT/COM/USB interface 402 on the mainboard 10 by LPT/COM/USB interface 401 realizes printing function.After the energising, primary power 5 by interface 501 with electric current divide supplementary biography on mainboard interface 502, scale body control panel 51 interface 503 and the interface 504 on the printer 4, make mainboard, scale body and the printer can operate as normal; Hard disk 6 is to be connected the storage that realizes this equipment by the communication port on the hard disk 6 601 with IDE/SATA mouth 602 on the mainboard 10, and the memory capacity of hard disk 6 can reach 40G, also can unrestrictedly enlarge according to requirement of client; Audio amplifier 7 is to be connected with AUDIO mouth 702 on the mainboard 10 by communication port 701 to connect the function that loudspeaker are realized audio frequency output by communication port 703 again; Case fan 8 is the functions that realize the fan heat radiation by communication port 801 and the interface 802 on the mainboard 10; The max cap. of internal memory 9 also can reach 1G; Mainboard 10 also has a plurality of I/O mouths to be used to connect USB external equipment and interior external keyboard etc.

This invention has effectively utilized the powerful CPU of INTEL; Can use the system operation of WINDOWS/LINUX, realize host and guest's demonstration, touch screen operation, print, weigh, cash register is in the multifunction electronic scale of one.
