Description

Electronic bar code recognition

Technical field

The present invention relates to a kind of product electronic bar code recognition, particularly a kind of electronic bar code recognition of air-conditioning.

Background technology

Present many companies control the region allocation of product by bar code, determine according to bar code which area certain product is assigned to, and can be protected interlocal the flowing of product, and reinforcement company are to the control of production marketing.But because present many product bar codes are the paper Jie bar code that is affixed on product surface, wearing and tearing or torn to pieces easily cause producer to carry out good control to the flow direction of product by bar code.

Summary of the invention

Technical problem to be solved by this invention is, a kind of bar code recognition simply and easily is provided, and this kind bar code is not fragile.

Technical problem to be solved by this invention is achieved by the following technical solution: a kind of electronic bar code recognition, it is characterized in that, and comprise the steps:

A) bar code writes and stores;

B) bar code reads and shows;

C) communications protocol is set;

D) display mode is set;

Step a comprises following substep:

A1. the bar code keyset reads the air-conditioning bar code by barcode scanner;

A2. the bar code keyset sends to the air-conditioner controller mainboard by infrared mode with barcode data;

A3. air-conditioner controller mainboard verification password, if the password mistake, process stops;

A4. air-conditioner controller mainboard verification bar code, preserve legal barcode data in EEPROM (electricity erasable memorizer);

Step b comprises following substep:

B1. remote controller sends and reads bar code command;

B2. the air-conditioning mainboard reads barcode data in EEPROM

B3. air-conditioning receives lamp plate run indicator show bar code data

Step c comprises following substep:

C1. communications protocol is set between bar code keyset and air-conditioner controller mainboard;

C2. communications protocol is set between remote controller and air-conditioner controller mainboard.

Because the present invention writes the air-conditioner controller mainboard by bar code reading rifle and bar code keyset with bar code information, and is stored in EEPROM, the bar code information storage is simple and convenient with reading, and bar code information can be preserved for a long time, and is not fragile.

Fig. 1 is an electronic bar code recognition flow chart of the present invention;

Embodiment

Referring to Fig. 1, a kind of electronic bar code recognition is characterized in that, comprises the steps:

1. bar code writes and stores;

2. bar code reads and shows;

3. communications protocol is set;

4. display mode is set;

Step 1 comprises following substep:

11. the bar code keyset reads the air-conditioning bar code by barcode scanner;

12. the bar code keyset sends to the air-conditioner controller mainboard by infrared mode with barcode data;

13. air-conditioner controller mainboard verification password, if the password mistake, process stops;

14. air-conditioner controller mainboard verification bar code, preserve legal barcode data in EEPROM (electricity erasable memorizer);

Step 2 comprises following substep:

21. sending, remote controller reads bar code command;

22. the air-conditioning mainboard reads barcode data in EEPROM;

23. air-conditioning receives lamp plate run indicator show bar code data;

Step 3 comprises following substep:

31. communications protocol is set between bar code keyset and air-conditioner controller mainboard;

32. communications protocol is set between remote controller and air-conditioner controller mainboard.

In said method, behind completing steps 1, can insert the verifying correctness step of bar code, the user can use the bar code keyset to send a certain specific barcode data to control main board in this process, whether this bar code of air conditioner control main board verification is consistent with the local bar code of depositing of controller, and gives the user with feedback information; In addition, behind completing steps 1, also can insert the password test step, the user can use the bar code keyset to send a certain specific cryptosystem to control main board in this process, and whether this password of air conditioner control main board verification is consistent with the local password of depositing of controller, and gives the user with feedback information.

Below in conjunction with this bar-code identification process of a case description:

One, bar code writes and preserves:

(1), the bar code keyset reads the air-conditioning bar code by barcode scanner;

(2), the bar code keyset sends the air-conditioner controller mainboard by infrared mode with barcode data;

(3), air-conditioner controller mainboard verification bar code, preserve legal barcode data in EEPROM;

Two, bar code reads and shows:

(1), remote controller sends and reads bar code command;

(2), the air-conditioning mainboard reads barcode data in EEPROM;

(3), air-conditioning receives lamp plate run indicator show bar code data;

Three, communications protocol

(1) bar code keyset and air-conditioner controller mainboard:

(1) initial with specific initial guiding level;

(2) barcode data begins by waiting to send out after the packing of agreement predetermined rule from a high position;

Adopt the mode of repeating transmission and verification when (3) sending, strengthen the reliability that data transmit;

(4) the air-conditioning mainboard is received and is preserved that buzzer rings once (0.5S) behind the legal barcode data;

(2) control device and air-conditioner controller mainboard:

(1) utilizes existing remote controller;

(2) length was pressed the light key 5 seconds;

(3) customer number is 1001;

Four, show standard

(1) charactron or LCD are arranged

(1) directly utilizes " temperature is set " section demonstration in " temperature is set " charactron or the LCD;

(2) barcode data begins per two one group flicker (bright 0.5S, 0.5S goes out) from a high position and continued for 3 seconds;

(3) charactron extinguished 2 seconds between every group, and buzzer rings once (0.5S)

(2) has only indicator light

(4) utilize run indicator to show;

(5) barcode data begins to glimmer by turn (bright 0.5S, 0.5S goes out) from a high position, ten expressions 0 of glimmering, flicker once represent 1, the flicker secondary represents 2, and the like;

(6) run indicator was extinguished 2 seconds between every, and buzzer rings once (0.5S).

Because the present invention writes the air-conditioner controller mainboard by bar code reading rifle and bar code keyset with bar code information, and be stored in EEPROM, during reading, call the bar code information that is stored in EEPROM by the air conditioner control main board, and on the display device that run indicator or other air conditioner carry show bar code data directly perceived, the bar code information storage of bar code recognition of the present invention is simple and convenient with reading, and bar code information can be preserved for a long time, and is not fragile.
