Specific embodiment
Embodiment:
The utility model relates to a kind of mobile communication relay based on low pressure carrier wave, wherein including host module, from
Machine module, Homeplug module, communication module and serial ports interconnecting module, the serial ports interconnecting module are mounted in acquisition equipment, institute
It states slave module to connect by cable with the serial ports interconnecting module, the GPRS module of concentrator is mounted on the communication module
On, and connect by cable with the host module, pass through power line carrier between the host module and the slave module
Carry out data remote transmission.
In the present embodiment, the relay is by host module, slave module, Homeplug module, communication module and serial ports
Interconnecting module composition.Realize following two aspect functions；
First is that the data of multiple terminals acquire function simultaneously.The main serial ports interconnecting module of the function is mounted on acquisition equipment
Upper replacement original GPRS communication module, slave module are connected by cable with serial ports interconnecting module, and serial ports interconnecting module is concentrator
Serial data and port status pass through network cable transmission and give slave module；It is preferable that host module is mounted on same area's base station signal
Place, the GPRS module of original concentrator is mounted in communication module, and is connect by cable with host module, host module,
Data remote transmission, host module compatible GPRS, CDMA, 3G, the communication such as 4G are carried out by power line carrier between slave module
Module, as shown in Figure 2.
Second is that carrier wave turns WIFI, wireless signal is received by 4G router, then the electricity in host module is connected by cable
Power cat module, WIFI signal is transmitted to basement signal blind zone by power line by Homeplug module, then is discharged by slave module
WIFI signal, the final WIFI signal covering for realizing basement, operating personnel are realized with after by connection WIFI using IP phone
Platform main website personnel real time phone call function, as shown in Figure 3.
Together by above-mentioned two function synthesized, so that it may know the mobile communication relaying dress based on low pressure carrier wave to be formed
It sets, as shown in Figure 4.
In the specific implementation process, the GPRS remote communication module of concentrator is removed first, not according to different specification
