Abstract
A kind of separate type can extend wireless data communication equipment, comprising: body; With body part from the data acquisition portion that also can extend movement within the specific limits for wireless data communication equipment relative to described separate type; And, data transfer part; Wherein, described body is connected by described data transfer part with described data acquisition portion.
Description
Technical field
The utility model relates to wireless communication field, and particularly, the utility model relates to the equipment that a kind of separate type can extend wireless data communication.
Background technology
In recent years, in information communication field, with fastest developing speed, most widely used is wireless communication technology.The radio communication realized in movement is commonly referred to as mobile communication again, and people are collectively referred to as wireless mobile communications the two.In the communication wirelessly carried out, signal power is the criterion of information transmission quality, important indicator especially.In the process of transmission, signal can weak causing cannot carry out effective data communication gradually along with the various impact in transmission path.
Traditional communication receipt module is integrated in device interior, when being in the weak or null zones of signal, just cannot communicate, now, if this equipment moving is constant, or can not installation site be changed, often cause the poor reliability of communications reception data system.
The mode that current solution signal difference does not cover has three kinds, and one, adjust base station equipment by operator, this mode settling mode relies on that telecommunications company's limitation is large, result has uncertainty completely.Two, install signal amplifier, such as utilize multiple Routers bridge etc., this mode technical requirement is high, cost is high, and this kind of mode has impact to telecommunications company's networking, and part operator has forbidden the installation of this kind equipment.Three, obtain useful signal by extending reception antenna, this kind of mode has distance limit usually to only have tens meters and DeGrain.
To sum up, need a kind of communication apparatus badly, when equipment moving inconvenience maybe cannot change installation site, overcome wireless signal weak, ensure the stable of transfer of data.
Utility model content
For the problems referred to above, the utility model provides a kind of separate type can extend wireless data communication equipment, comprising: body; With body part from the data acquisition portion that also can extend movement within the specific limits for wireless data communication equipment relative to described separate type; And, data transfer part; Wherein, described body is connected by described data transfer part with described data acquisition portion.
Wherein, described data acquisition portion comprises the data reception portion for receiving data from wireless network, for the data conversion unit changed described data.
Wherein, to be transferred to the receiving port of described body by the transmission link in described data transfer part through the described data of conversion.
Wherein, described data carry out inverse conversion by described receiving port to described data after being received by described receiving port.
Wherein, the described data after inverse conversion are done follow-up use after the data processing division process of described body.
Wherein, described wireless network includes but not limited to GPRS network, 3G network, 4G network.
Wherein, described data carry out transmitting and processing with the form of RS232 in described data acquisition portion and in described body after format conversion.
Wherein, described data transfer part comprises RS485 cable, described in be converted to RS232/RS485 conversion, described link is RS485 link, described reverse be changed to RS485/RS232 conversion.
By the way, user is without the need to the GPRS Principle of Communication of complexity and TCP/IP, udp protocol, the wireless network that can realize original serial equipment without the need to changing program connects, can be used for long haul communication transmission, realize data acquisition, upload and download, thus solve because signal strength signal intensity is weak and cannot the problem of data communication.
Accompanying drawing explanation
Fig. 1 is the structural representation that can extend wireless data communication equipment according to the separate type of the utility model embodiment.
Embodiment
Below, wireless data communication equipment can be extended to separate type described in the utility model by reference to the accompanying drawings further to describe in detail.
Fig. 1 is the structural representation that can extend wireless data communication equipment according to separate type described in the utility model.It is worth mentioning that, it can be any equipment possessing radio communication function that described separate type can extend wireless data communication equipment, such as, can be placed in the inner TV for broadcast advertisement or other audio-video frequency contents of building, audio amplifier also can be that the public transport being positioned at a certain remote point shows station board automatically.This kind equipment has a feature usually, and namely self is mobile restricted, but needs to receive data in a wireless communication environment.
As shown in Figure 1, separate type described in the utility model can extend wireless data communication equipment 100 comprise body 101, be separated with described body 101 and can extend the data acquisition portion 102 of movement within the specific limits for wireless data communication equipment 100 relative to described separate type, described separate type can extend wireless data communication equipment 100 and also comprise data transfer part 103.Wherein, described body 101 is connected by data transfer part 103 with described data acquisition portion 102.Described data acquisition portion 102 comprises the data reception portion 104 for receiving data from wireless network, and the data conversion unit 106 for changing described data, described data through changing are transferred to the receiving port 105 of described body 101 by the transmission link in described transport part 103, after the inverse conversion of described receiving port 105, described data are done follow-up use after the data processing division 107 of described body 101 processes.Preferably, described wireless network includes but not limited to GPRS network, 3G network, 4G network.
Preferably, described data carry out transmitting and processing with the form of RS232 in described data acquisition portion 102 and in described body 101 after format conversion.
Preferably, described data transfer part 103 comprises RS485 cable.
Preferably, described in be converted to RS232/RS485 conversion, described link is RS485 link, described reverse be changed to RS485/RS232 conversion.
When signal condition of wireless network declines, described separate type can extend reception and the process that wireless data communication equipment normally cannot carry out data, now, the movement flexibly of described data acquisition portion 102 can be made, until it moves to the good position of signal condition of wireless network, continue to receive data from described wireless network.
After a series of conversion being carried out to data in described data acquisition portion 102, send data to described body 101 by RS485 cable, then, carry out changing in described body 101 thus described data can be used suitably.
The utility model adopts the mode of transparent transmission, user is without the need to the GPRS Principle of Communication of complexity and TCP/IP, udp protocol, the wireless network that can realize original serial equipment without the need to changing program connects, and can be used for long haul communication transmission, realizes data acquisition, upload and download.By utilizing RS485 cable to expand, the data receiver that separate type described in the utility model can extend wireless data communication equipment extends distance and can reach 300 meters, thus solves because signal strength signal intensity is weak and cannot the problem of data communication.
Those skilled in the art should know; the description that can extend wireless data communication equipment to described separate type in the utility model specification is principle; it is not appreciated that restriction of the present utility model, does not anyly depart from the utility model purport and all falls into the utility model scope required for protection to point improvement that utility model is carried out.
