Turn to carry out relay process by repeater by the process for carrying out script in terminal body and the base stations GPRS, relative to
The transmission mode of the prior art can effectively improve transmission range；In addition the root between proximal end converter and distal end converter
Different communication modes is used according to demand, can more improve communication efficiency.
Description of the drawings
It, below will be to needed in embodiment description in order to illustrate more clearly of the technical solution of the utility model
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the utility model, for
For those of ordinary skill in the art, without creative efforts, other are can also be obtained according to these attached drawings
Attached drawing.
Fig. 1 is the structural schematic diagram of repeater provided by the utility model.
Specific implementation mode
It is clearer for the structure and advantage that make the utility model, the structure of the utility model is made below in conjunction with attached drawing
It is further described through.
Embodiment one
The utility model provides more communication type repeaters based on GPRS, more communication type repeaters, including：
The proximal end converter and distal end converter of interconnection, proximal end converter by cable either shielding line or
RS485 lines are connect with terminal body, and distal end converter is then communicated by built-in GPRS communication modules with the base stations GPRS；
Wherein, proximal end converter is connected with distal end converter by least one communication mode.
In force, as shown in Figure 1, more communication type repeaters include two portions of proximal end converter and distal end converter
Part is attached by communication therebetween.In the prior art, terminal be directly with the communication mode of GPRS
It is communicated with the base stations GPRS, in order to make up the defect that communication efficiency is bad between terminal body and the base stations GPRS, passes through proximal end
The information that script is transmitted by converter and distal end converter between terminal body and the base stations GPRS relays, to increase
The ability that strong information is transmitted.
Specifically, in more communication type repeaters based on GPRS, including proximal end converter and distal end converter, proximal end
Converter is connected with terminal body, and distal end converter is communicated with the base stations GPRS, in this way, originally in terminal body and GPRS bases
The process carried out of standing turns to carry out relay process by repeater, and transmission mode compared with the existing technology can effectively improve biography
Defeated distance；In addition it uses different communication modes according to demand between proximal end converter and distal end converter, can more improve logical
Believe effect.
It should be noted that communicated using various ways between proximal end converter and terminal body, including cable,
Shielding line or RS485 lines.Best communication mode is chosen according to specific communicating requirement or communication efficiency, to ensure end
Communication data between end ontology and proximal end converter will not be lost.
Optionally, at least one communication mode, including：
The wireless private network of specific frequency；Or
Bandwidth carrier based on power line；Or
Wired connection based on shielding line.
In force, in order to meet a variety of different data transmission environments, between proximal end converter and distal end converter
A variety of different communication modes can be used to be transmitted into row information.
The wireless private network of specific frequency can typically be used；Or the bandwidth carrier based on power line；Or it is based on shielding line
Wired connection.It is different according to practical communication environment difference or use demand in actual use, select different communication modes.
During selection, wireless private network/bandwidth carrier/wired equal communication modes can be automatic to detect according to field condition
Which kind of communication mode effect is optimal and suboptimum, is then used as primary channel.When actually switching over, engineering staff is needed
Manual switching is carried out, i.e., existing connection type is switched to the permitted connection type of current environment, to most to adapt to work as
The communication mode of the mode of preceding environment is relayed.
For example, in repeater original communication mode be based on wireless private network, but under current environment, wireless signal compared with
Difference causes transmission packet loss very high, can the communication mode in repeater be switched to the bandwidth carrier based on power line at this time
Mode or wired connection mode based on shielding line, can make up the defect of wireless private network communication mode, to be promoted in this way
The using effect of repeater.
In particular to micropower wireless frequency 470MHZ, wideband carrier frequency is 2~12MHZ, and wired connection is mobile joins
Passband section.
Optionally, the proximal end converter, including：
The first signal processor of signal is sent out for receiving and processing terminal body, and is connected with the first signal processor

The distal end converter, including：
The second communication unit of data transmitting and receiving is carried out with the first communication unit, and connect with the second communication unit
Second signal processor, second signal processor are connected with GPRS communication modules.
In force, proximal end converter passes through the first signal processing first after receiving the information that terminal body is sent out
Device received after processing, and then according to current environment and demand, select suitable communication mode, and then by specific
One kind in three kinds of wireless private network of frequency, the bandwidth carrier based on power line, the wired connection based on shielding line modes, passes through
First communication unit transmits information to distal end converter.
In the converter of distal end, after receiving information by the second communication unit corresponding with the first communication unit, it will connect
The information received is transmitted in the second communication unit, so that the information that terminal body is sent is transmitted to GPRS by the second communication unit
Communication module finally enables the information that terminal body is sent be transmitted through the base stations GPRS by GPRS communication modules, relative to existing
There is terminal body in technology directly to transmit information to the scheme of the base stations GPRS, using this repeater can improve signal transmission away from
From, in addition between proximal end converter and distal end converter according to demand use different communication modes, prevent single communication side
The defect that formula causes transmission limited improves communication efficiency.
The utility model provides more communication type repeaters based on GPRS, including the proximal end converter of interconnection and
Distal end converter, by cable, either shielding line or RS485 lines are connect proximal end converter with terminal body, and distal end converter is then
