Description
Technical Field
The invention relates to the technical field of administrative law enforcement printing, and particularly provides a law enforcement printing system based on an intelligent mobile terminal.
Background
In the existing on-site administrative law enforcement and inspection business process, law enforcement and inspection personnel cannot get rid of the traditional handwriting office mode. That is, the law enforcement officer needs to manually fill out the law enforcement examination record or the penalty record on site and perform the secondary entry of the data on the office system at the later stage. This is contrary to the principle of electronic and paperless law enforcement data of most e-government systems.
To address this pain, a completely new, digital law enforcement and office printing system must be employed. And considering the difference in economy, technology and existing e-government system level among various places, various departments, the system must have the characteristics of low cost, high versatility and simple operation.
Disclosure of Invention
The technical task of the invention is to provide a law enforcement printing system based on an intelligent mobile terminal, which has the advantages of low cost, high universality and simple and convenient operation and can meet the administrative law enforcement requirement of an e-government system.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a law enforcement printing system based on intelligent Mobile terminal, includes printing apparatus and intelligent Mobile terminal, is equipped with on the intelligent Mobile terminal and prints the processing unit, and intelligent Mobile terminal is connected with printing apparatus through printing the processing unit.
Preferably, the printing device is a bluetooth printer.
The bluetooth printer uses bluetooth 4.0 agreement to be connected with mobile intelligent terminal, uses 57 to 50mm package thermal printing paper as the printing consumptive material, can select to use ordinary thermal printing paper or the thermal printing paper of taking the non-setting adhesive according to actual need. The resolution of the printer is 203dpi and 384 dots/line, and after the Bluetooth connection is established, the Bluetooth connection mode can be used for sending instructions and exchanging data with the terminal.
Preferably, the printer is responsible for printing, printing plain text information or printing graphic information represented by a two-dimensional code.
Preferably, the intelligent mobile terminal is a mobile phone or a tablet computer.
Preferably, the intelligent mobile terminal is a device for operating andorid8.0 +.
The intelligent terminal is connected with the printer through the Bluetooth technology, and the intelligent terminal must have the connection capability of more than 4.0 Bluetooth.
Preferably, the intelligent mobile terminal exchanges data with the printing device, and the data exchange comprises instruction sending, graphic processing and word processing.
Preferably, the print processing unit is a bluetooth thermal printing unit. And the Bluetooth thermal printing unit is internally provided with Bluetooth printer printing software. The bluetooth printer contains 24 × 24 GB18030 character set G word stock by default, and needs to generate 48 × 48 lattice word stock in consideration of actual application scenes (such as titles and the like). The 48 x 48 lattice library was generated using Java code as a Unicode character set encoded in UTF-16 LE. Each character theoretically occupies 48 × 48/8-288 bytes, and the reason for aligning addressing considering physical storage hardware occupies 512 bytes/character. The 16-bit code is computed directly with 65536 characters for ease of computation, and the word bank takes up 32MB of memory space.
Preferably, the printing unit processes raw data in the smart mobile terminal, converts the character string into byte data, and binarizes and formats the picture into a format recognized by the printing device.
Since the bluetooth printer supports only black-and-white printing and does not support grayscale printing, it is necessary to perform binarization conversion on a printed picture. The binarization conversion is processed in a manner of traversing pixel values of the picture. Pixels with a pixel value of 0 in the RGB model are collectively converted into 1 (black), and pixels other than 0 are collectively converted into 0 (white).
Because the basic printing unit of the bluetooth printer is 8 pixels in the vertical direction, the bluetooth printer needs to convert the pictures stored in the matrix form of the conventional row and column scanning lines into the format of the matrix format of 8 pixels in the vertical direction.
The software is responsible for starting the Bluetooth equipment of the terminal, scanning the surrounding Bluetooth printers and realizing socket connection. The control instruction is different according to the different printing contents.
1) Underlying GBK encoded byte data
Can be directly sent to a printer through a socket, and a word stock built in the printer can directly print 24 characters on thermal paper.
2) Black and white BMP picture (Picture, two-dimension code, custom word stock)
Printing needs to be done in cmd + parameter form. The graphic print command is a 6+ N byte command, with N representing the width of the graphic. The command fixes the first 4 bytes to be 0x0,0x1B,0x2A,0x1, and the last two bytes to be the width of the picture, where the 4 th byte is the lower 8 of the graphic width N and the 5 th byte is the upper eight bits of the graphic width N. The graphic printing is performed line by line in units of 8 pixels per line.
In the law enforcement printing system based on the intelligent mobile terminal, the thermal printer is connected with the intelligent mobile terminal through a Bluetooth technology, data exchange is carried out through printing software of the Bluetooth printer, the mobile intelligent terminal runs the printing software of the Bluetooth printer, and data in the law enforcement process are gathered, processed, converted and printed through the printing software. The system can be used for daily administrative law enforcement inspection work of an administrative law enforcement officer, realizes the on-site printing of law enforcement results in the administrative law enforcement inspection process, can be combined with a two-dimensional code technology, directly prints the download address of a legal document on a paper receipt in a two-dimensional code mode, and realizes efficient and convenient modernized law enforcement.
Compared with the prior art, the law enforcement printing system based on the intelligent mobile terminal has the following outstanding beneficial effects: the law enforcement printing system based on the intelligent mobile terminal is low in cost, high in universality and simple and convenient to operate, realizes field printing of law enforcement results in the administrative law enforcement inspection process, can be combined with a two-dimensional code technology, directly prints a downloading address of a legal document on a paper receipt in a two-dimensional code mode, realizes high-efficiency and convenient modernization law enforcement, can meet the administrative law enforcement requirements of an e-government system, and has good popularization and application values.
