Embodiment
Principle of the present utility model is to realize the purpose of while to a plurality of Bluetooth device to send information by setting up a plurality of system threads.Wherein, thread described in the utility model is meant the set of one group of instruction, or the particular segment of program, and it can independent execution in program.Described multithreading is meant permission a plurality of instruction streams of concurrent execution in program, and each instruction stream all is called a thread, and is independent mutually to each other.Multithreading makes the work of a plurality of thread parallels to finish the multi-task, can improve the efficient of system.
Specify the utility model below in conjunction with accompanying drawing.
See also Fig. 1, it is a kind of multithreading bluetooth information broadcast platform structure schematic diagram of the utility model embodiment.This thread bluetooth information broadcast platform comprises a processor, two usb 1s 05, two bluetooth rods 107, network interface 109 and power supply 111.The processor of present embodiment is S3C2440 chip 103, and usb 1 05, network interface 109 and power supply 111 all link to each other with S3C2440 chip 103.Bluetooth rod 107 is connected on the usb 1 05, be used to detect in the Bluetooth signal coverage bluetooth equipment and to Bluetooth device to send information.Network interface 109 is connected with netting twine 113, and multithreading bluetooth information broadcast platform is connected in the network.
Quantity that it should be noted that above-mentioned usb 1 05 is corresponding with the quantity of system thread, if processor has more thread, more usb 1 05 can be set link to each other with processor, as 34 or more usb 1 05.
See also Fig. 2, it is a kind of processor structure schematic diagram of the utility model embodiment.This processor comprises bluetooth search module 203, register 205 and bluetooth sending module 207.Bluetooth search module 203 links to each other with bluetooth rod 107, is used to detect bluetooth equipment in the Bluetooth signal coverage.Register 205 links to each other with bluetooth search module 203, is used to deposit bluetooth search module 203 detected bluetooth equipment information.Bluetooth sending module 207 links to each other with register 205 and bluetooth rod 107 respectively, is used for sending initialize data by the plurality of sub thread to the detected bluetooth equipment of bluetooth search module.
Introduce the course of work of multithreading bluetooth information broadcast platform below. at first bluetooth search module 203 is implemented inquiry by the bluetooth equipment that is connected in the 107 pairs of Bluetooth signal coverages of bluetooth rod on the usb 1 05, detection has or not bluetooth equipment to appear in the platform bluetooth information coverage. after having detected the bluetooth equipment appearance, bluetooth search module 203 forms a tables of data with the address information of bluetooth equipment, and writes in the register 205 of processor.
Then, bluetooth sending module 207 obtains the tables of data of bluetooth equipment from register 205, and the area information different according to bluetooth equipment in the tables of data, creates out several threads, and the preset information of appointment sent to bluetooth equipment in the Bluetooth signal coverage, finish transmission of Information.Wherein, these threads can carry out simultaneously, and in other words, bluetooth sending module 207 can be simultaneously to a plurality of Bluetooth device to send information in other words.
Especially, for the bluetooth equipment that does not retrieve once more at certain time intervals, register 205 can be taked the table that clears data perdurabgility.Exactly when searching an equipment for the first time, add an initial time in the tables of data, just make this time into new time when searching again for the second time, and this initial time with surpass a time interval now, left in the Bluetooth signal scope with regard to devices illustrated, so just can remove this facility information tabulation.
See also Fig. 3, it is the another kind of processor structure schematic diagram of the utility model embodiment.Compare with Fig. 2, present embodiment also includes data operation modules 303, data recordin module 305 and system monitoring information module 307.Data operation modules 303 links to each other with register 205 and bluetooth sending module 207 respectively with data recordin module 305, and system monitoring information module 307 links to each other with bluetooth search module 203 and bluetooth sending module 207 respectively.
After a new bluetooth equipment is caught in, data operation modules 303 can be called, and read tables of data in the register 205, whether differentiate this equipment exists in the tables of data of register 205, if exist then change initial time, if there is no then set up tables of data, write initial time, information channel etc.When being ready for sending data to certain equipment in the tables of data, bluetooth sending module 207 also need call data operation modules 303, check this equipment whether to receive the information that platform sends, this equipment is once attempted having connected several inferior data record by platform, judges whether the information that will send and reattempt transmission several inferior with this.
Article one, information or file are received or are rejected when receiving, data recordin module 305 can be called, and in tables of data, carry out record, the data owner of record will comprise: transmitting time, receive Bluetooth address, send Bluetooth address, receiving flag is changed to and sends etc.And platform is attempted to set up with equipment the process record of communication link and also can be write in the tables of data by data recordin module 305.
System monitoring information module 307 can be called by the mode of hardware interrupts and software interrupt, and this module is responsible for monitoring unusually simultaneously, also can finish the protection of system and application program simultaneously according to configuration file.
Than prior art, the utlity model has following advantage: the utility model has been broken through the data transfer mode of existing Bluetooth technology " point " to " point ", by setting up the data transmission channel of multithreading, realize the function of while to a plurality of Bluetooth device to send information, widened the use field of Bluetooth technology, especially made Bluetooth technology can apply to the field of large information capacity transmission such as broadcasting, medium.
More than disclosed only be several specific embodiment of the present invention, but the present invention is not limited thereto, any those skilled in the art can think variation, all should drop in protection scope of the present invention.
