Description

The utility model relates to the field of trade using computer technology, in particular, to use for conducting payment transactions in various financial systems, to methods and systems of payments and other cash transactions using information transfer using wireless communications, and can be used for sale goods and the provision of various types of services with the printing of a cash receipt on a heat-sensitive tape.

The market of goods and services currently uses many different models of smart terminals containing thermal printing mechanisms. The charging system of such devices is based on the use of batteries (rechargeable batteries) as sources of energy storage, which is spent on ensuring the operation of the entire device as a whole, while compact batteries can not give large currents to ensure high speed printing. This circumstance encourages the developers of such devices to compromise, reducing printing speed compared to the printing speed of stationary devices. However, even such currents, which provide sufficiently slow printing of receipts, are significant for compact batteries, which inevitably leads to accelerated degradation of the latter, reducing their useful life and limiting the life of the devices as a whole.

At the same time, modern developments are known in which high-capacity ionistors-capacitors are used as energy storage devices. Such energy storage devices are used primarily as a backup, and not the main, power source, for example, transport systems, aircraft, emergency and uninterruptible power supply systems for communications and telecommunications, etc. In particular, a portable electric lamp RU 2234638 C2, F21S 9/04 is known. 08/20/2004, in which the ionistors are used to recharge the lamp in the process of lighting the object. A portable information storage device is known in which large-capacity ion-capacitors are used as a backup power source in the absence of the main source provided by the device design - RU 108167 U1, 09/10/2011, i.e. a hybrid power source is used. However, energy sources operating only on ionistors have not yet been used as the main power sources for portable devices, in particular those used in thermal printing mechanisms.

Closest to the claimed technical solution is the patent of Poynt Co. US 9092766 B1, G06K 15/00, 07/28/2015, in which a smart payment terminal with the function of printing receipts by means of a thermal printer is disclosed. In a known solution, the tablet part of the smart terminal is connected to a thermal printer, and a battery located on the back of the tablet part is used as an energy storage device for the entire device. The thermal printing mechanism is configured to replace the printed ribbon. The disadvantage of this device is the presence of an energy storage device with low operating currents that provide low printing speed (no more than 30 mm / sec), which in modern conditions of use of a smart terminal increases the time of customer service.

In connection with the foregoing, the technical problem is the creation of a smart terminal that provides thermal printing of checks with high speed, as well as increasing its reliability and service life in general.

The technical result provided by the claimed utility model is to supplement the conventional smart terminal energy storage scheme, made on lithium-ion batteries, with the ionistors used for thermal printing of checks, which will achieve not only high printing speed, but also reduce the overall dimensions of the smart terminal to increase the reliability and durability of its work, as well as reduce the price of the product, which is important in modern conditions of development of the market of goods and services.

The envisaged technical result is ensured by the fact that the smart terminal comprises a tablet portion located in a plastic case, a thermal printer and batteries associated with it. In this case, the thermal printer is made in the form of a removable unit, in the housing of which there is an additional energy storage device designed for thermal printing of checks. The specified energy storage device is made in the form of ionistors, which are installed in parallel mode for their continuous power supply and have the ability to switch to serial connection to ensure thermal printing of the checks.

The technical solution is illustrated by the following drawings:

in FIG. 1 shows a general view of a smart terminal with a tablet portion and a thermal printer;

in FIG. 2 shows an electronic board with components for controlling a thermal printing mechanism and three ionistors;

in FIG. 3 shows a block diagram of the operation of the thermal printing mechanism;

in FIG. 4 shows a diagram of the use of ionistors in a smart terminal.

The smart terminal contains (see Fig. 1) a tablet portion (2) enclosed in a common plastic housing (1) with a thermal printer (3) made in the form of a removable unit. The tablet part (2) contains a touch panel, a display and four lithium-ion batteries, as well as all the elements and modules necessary for the full operation of the device (in particular, a microphone, speakers, antennas, calculation modules, cash register, etc.) that are not indicated because they are not the objects of consideration of this application. In the thermal printer (see Fig. 2) on the electronic board (4) there is an additional energy storage device in the form of ionistors (5) (large capacitors), which provides direct printing of checks on the thermal tape. The thermal printer is powered and controlled (see block - diagram of Fig. 3) via the USB connector (block 1). Three ionistors (5) (see FIG. 2) installed in a parallel connection (block 4) are fed through a pulse power converter (block 2). The switching circuit (block 6) can put the ionistors in parallel mode to obtain triple voltage, which is necessary to power the thermal printing mechanism (block 8). The microcontroller (block 5) is powered through a pulse voltage converter (block 3) and controls the thermal printing mechanism directly and through a bridge chip to control the stepper motor (block 7). The electronic board (4) (Fig. 2) of the smart terminal contains components for controlling the thermal printing mechanism and three ionistors (5), from the energy of which thermal printing of the smart terminal checks is carried out.

Ionistors (capacitors) are charged in parallel (Fig. 4). For this, the n-channel transistors VT10, VT11 must be open, and the p-channel VT16, VT17 - closed. For use in the operating mode for thermal printing of the checks, the ionistors are switched in serial connection using mosfet transistors, while VT10, VT11 must be closed, and VT16, VT17 open.

As an example, 25F ESHSR-0025CO-001R7 ionistors can be used, which are fed through a switching power converter, for example MIC2267, in parallel with current limitation. A microcontroller, such as the LPC1768FBD100, is powered from the USB connector via a switching voltage converter, such as ST1S12GR. The microcontroller controls the thermal printing mechanism, for example SS205-V4-LV, directly and through a bridge chip to control a stepper motor, for example DRV8835DSSR. The advantage of using ionistors is a large working current, which, based on the documentation for the specified thermal printing mechanism, allows you to provide high-speed printing characteristics of 100 mm / sec. According to the USB2.0 standard, 2.5 W taken from the port is enough to power the ionistors and supply power to the rest of the smart terminal circuit.

The final consumer characteristics are that we get standard 2.5 W from USB, and we can spend up to 64 W at the time of printing.

The given indicators confirm that as a result of using such a work scheme, it becomes possible to carry out thermal printing only through the use of ionistors, while ensuring a high printing speed of up to 100 mm / sec, which is not possible for printing checks in smart terminals using only compact batteries.

Along with the indicated advantages, the ionistors have a rather long service life, which also improves the possibility of maintenance of the smart terminal.

Smart terminals made on the basis of the described design will allow to reduce overall dimensions and facilitate the design of such devices, increase the service life of built-in batteries by reducing operating currents, which is ensured by the presence of an additional energy storage in the form of ionistors, and also reduce the consumer price of a smart terminal, including number by reducing the power used in the device power supply.
