Abstract
The invention discloses a mini-type thermal printer based on Bluetooth communication, which comprises a main control chip, wherein an interface module, an RAM, an ROM, a mini-type thermal-printing head, a stepping motor driver module and a printing head state detection module are connected onto the main control chip; a USB interface is arranged in the interface module; the thermal-printing head and the stepping motor driver module are supplied with power by a power supply module; the main control chip is communicated with an upper computer through the interface module; a Bluetooth module is further arranged in the interface module; all the Bluetooth protocol stacks are solidified in a chip of the Bluetooth module; the Bluetooth module is connected with the main control chip through a UART assembly. The mini-type thermal printer integrates a electromechanical technology, an embedded technology and a wireless Bluetooth technology, can be in wireless communication with any device provided with a Bluetooth interface by adopting a serial port transparent technology, has the advantages that the size is small, the noise is low, the printing is clear, and the maintenance is convenient, and meets the requirement of people for printing in places with small space and without finite network access.
Description
Technical field
The present invention relates to thermal printer technical field, particularly relate to a kind of minitype thermal printer based on bluetooth communication.
Background technology
Thermal printing technique scribbles the printing paper of chemical heat-sensitive materials as on heat-sensitive paper, label paper by the area of heating surface, makes coating blackening, obtains the technology of image.Thermal printer is on the basis of thermal printing technique, and a kind of set electron technology produced along with the high speed development of computer technology, Controlled by micro computer technology, Bluetooth technology, material technology, computer technology, automatic technology, Bluetooth technology, material technology are in the high-tech product of one.Minitype thermal printer has the features such as volume is little, resolution ratio is high, noise is low, printing writing is clear, print speed is fast, the ratio of performance to price is high, working service is convenient, belongs to non-impact printer.
Bluetooth technology is a kind of short-distance wireless communication technology.Follow Open System Interconnection reference model, adopt the protocol stack of layering.HCI is positioned at L2CAP(logic link control and the adapting protocol of bluetooth protocol repertory) layer and LMP(LMP Link Manager Protocol) between layer, be the interface of software restraint in bluetooth protocol repertory.
At present, when place that is little in spaces such as running trains, that lack finite element network access needs to print, common thermal printer cannot satisfy the demands.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide the minitype thermal printer based on bluetooth communication, volume is little and can carry out radio communication with the equipment of any band blue tooth interface, realizes blue teeth wireless printing function.
In order to achieve the above object, the present invention is by the following technical solutions: a kind of minitype thermal printer based on bluetooth communication, comprise main control chip, main control chip is connected with interface module, RAM, ROM, miniature thermal printing head, driving stepper motor module and printhead state detection module, USB interface is provided with in interface module, thermal printing head and driving stepper motor module are powered by supply module, host chip is communicated with host computer by interface module, also bluetooth module is provided with in described interface module, whole bluetooth protocol repertories is have cured in the chip of described bluetooth module, described bluetooth module is connected with host chip by UART assembly.
Described UART assembly comprises transmit block, receiving-member, Baud rate generator and control unit.
Printhead state detection module mainly detects some status informations of minitype thermal printer, as the temperature of scarce paper, hang-up and thermal printer.Comprise scarce paper detection module and printhead temperature control module.In time detecting that appearance lacks paper, main control chip does not have printing paper by display screen reminding user; When detecting that thermal head is in higher temperature, main control chip judges that whether temperature is reasonable, and the time of calculating heating next time thermal printing head is to facilitate the basic stationary temperature of thermal printing head.
The module of paper feeding when driving stepper motor module mainly controls the printhead prints of temperature-sensitive, be related to the quality and speed etc. during thermal printing, main control chip produces stepper motor driven clock signal according to the setting of print speed, and clock signal is just transformed into the drive singal of motor through conversion.
The invention has the beneficial effects as follows: minitype thermal printer of the present invention integrates mechanical & electrical technology, embedded technology, wireless blue tooth technology, adopt serial ports transparent technology can carry out radio communication with the equipment of any band blue tooth interface, have that volume is little, noise is low, print advantage clear, easy to maintenance, meet people in space the little demand lacking again the place needs such as finite element network access and print.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of minitype thermal printer of the present invention;
Fig. 2 is the structured flowchart of UART assembly of the present invention.
Detailed description of the invention
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
A kind of minitype thermal printer based on bluetooth communication, as shown in Figure 1, comprise main control chip, main control chip is connected with interface module, RAM, ROM, miniature thermal printing head, driving stepper motor module and printhead state detection module, USB interface is provided with in interface module, thermal printing head and driving stepper motor module are powered by supply module, host chip is communicated with host computer by interface module, also bluetooth module is provided with in interface module, whole bluetooth protocol repertories is have cured in the chip of bluetooth module, bluetooth module is connected with host chip by UART assembly.
As shown in Figure 2, UART assembly comprises transmit block, receiving-member, Baud rate generator and control unit.Wherein transmit block has the fifo buffer sending shift register and 16 bit byte sizes to form, receiving-member has the fifo buffer receiving shift register and 16 bit byte sizes to form, send shift register and add the data sending FIFO and interrupt, in like manner receiving-member completes reception.
