Abstract
The utility model discloses a bidirectional transparent transmission device with a wireless serial port, which comprises a serial port module, a micro processor and a wireless module, wherein the serial port module adopts a standard UART port which can also be expanded into various serial ports such as an RS-232-C, an RS-422 port, an RS485 port, a USB port and a CAN port; a C51-inner core 8-bit singlechip is adopted by the micro processor; and the wireless module adopts a wireless radio-frequency chip of NFR series of the NODIC company. By adopting the method of transparent transmission, the bidirectional transparent transmission device with the wireless serial port is nearly non-existent to an external serial device, thus not influencing the data transmission of the original serial device, and further leading the bidirectional transparent transmission device to have wide applicability and practicality, wider using range, more convenient operation, more reliable conversion, higher speed, higher accuracy, higher cost-performance ratio and more convenient maintenance, greatly improving the efficiency for users and avoiding the trouble of the laying of circuits.
Description
Technical field
The utility model relates to the two-way transparent transmission device of a kind of wireless serial, is specially adapted to the wireless communication system of short-distance wireless data acquisition, intelligent multipoint control system.
Background technology
We have really entered the epoch that wireless technology is ubiquitous now.Home intelligence system, sub-district safety defense monitoring system, GPS navigation wireless technology just constantly change our life style, make people's life more comfortable, fine, safety.The application of canonical systems such as system, agriculture gardens monitoring system has represented the continuous expansion and the development of wireless technology.Radio communication comprises long apart from wireless from communication system and short distance radio communication system.Short distance radio communication system, along with the continuous development of digital communication and computer technology produces, short-distance wireless communication and long distance wireless communication have a lot of differences, mainly contain the low powered battery that is fit to of radio transmitted power, general power at several 1mW to less than 10mW, communication distance from several centimetres to hundreds of rice, use omnidirectional antenna or PCB antenna, not intercepted by environment influences, and is generally operational in advantages such as ISM band.In the middle of different digital signals converges to by wireless transmission link or terminal equipment when processing, the wireless signal of various different manufacturers, different brands, dissimilar external equipment is during with different protocol transmission information, just need different software, different equipment that it is carried out code parsing, such situation has increased cost, has increased the maintenance difficulties of system, has reduced efficient.
The utility model content
The utility model provides a kind of wireless serial two-way transparent transmission device in order to address the above problem, and is specially adapted to the wireless communication system of short-distance wireless data acquisition, intelligent multipoint control system.
The two-way transparent transmission device of wireless serial is characterized in that: comprise serial port module, microprocessor and wireless module composition.Described serial port module adopts standard UART interface also can expand to RS-232-C, RS-422, RS485, USB, many kinds of serial line interfaces of CAN, has good versatility, model applied widely.
Described microprocessor adopts 8 single-chip microcomputers of C51 kernel, and is cheap, reliable at a high speed, rich interface.
Described wireless module adopts the NRF series radio frequency chip of NODIC company, and the integrated level height is with low cost, strong interference immunity.
Principle of the present utility model is: it is that external equipment sends data to serial port module that the information between from the external equipment to the wireless module sends, serial port module is sent to microprocessor with data, microprocessor sends data through wireless module after data being encoded and packed handling again; Data Receiving between from the wireless module to the external equipment is after wireless module receives wireless data, radio equipment data is sent to microprocessor, microprocessor through to data unpack with decoding processing after, send the data to external equipment through serial port module again.The utility model device is not analyzed data packet form, data length and the data encryption mode etc. of outside serial equipment, just former serial data is carried out the secondary package according to the Communication Control agreement that self defines and add address and id information etc. simultaneously, receive and carry out control protocol and resolve at receiving terminal then, restore source data packet at last and send to external equipment, realize the double-direction radio transparent transmission of serial data with this by serial ports.
Effect of the present utility model is:
The two-way transparent transmission device of wireless serial is equivalent to not exist for outside serial equipment owing to adopt the transparent transmission mode, therefore can not influence the transfer of data of former serial equipment, therefore have extensive applicability and practicality, the scope of application is wider, and more convenient operation is changed more reliable, speed is faster, more accurate, cost performance is higher, keeps in repair more convenient, the user is raised the efficiency greatly, avoided the trouble of line arrangement.
