Wireless public network communication module (GPRS or CDMA),
With the technology development of wireless public network communication, 2G, 3G, the 4G communication technology also experienced.The 2G technology of early stage because
Construction is early, backward in technique, occupies good radio band, and maintenance cost is high, in consideration of it, operator determines to close 2G network,
Develop the band resource released for following 5G.This just brings the most of communication for all using 2G of a problem electric power terminal,
Utilities Electric Co. just faces used equipment to be eliminated or handle and upgrades to 4G with regard to equipment communications portion.
Utility model content
The utility model needs to upgrade to pressure brought by 4G for the most of communication for all using 2G of current electric power terminal
Power, provides a kind of Internet of Things wireless communication routing device, and the 2G communication that electric power terminal largely uses is upgraded to 4G communication, installation
Facilitate investment also small.
The technical solution of the utility model is: a kind of Internet of Things wireless communication routing device, including passes through net with electric power terminal
The ethernet nic and microprocessor of line connection；Further include 4G network interface, under the control of the microprocessor realize with
The too module mutually converted of network card interface and 4G network interface.
The 2G for largely using electric power terminal may be implemented using the Internet of Things wireless communication routing device of the utility model
Communication upgrades to 4G communication, and investment easy for installation is also small.
Further, in above-mentioned Internet of Things wireless communication routing device: further including RS485 interface, in the micro process
The module that RS485 interface and 4G network interface are mutually converted is realized under the control of device.
Further, in above-mentioned Internet of Things wireless communication routing device: the microprocessor is RISC instruction framework, work
The processor of industry grade 32 C0 kernels.
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Detailed description of the invention
Fig. 1 is 1 system block diagram of the utility model embodiment.
Fig. 2 is 2 block architecture diagram of the utility model embodiment.
Specific embodiment
Embodiment 1, as depicted in figs. 1 and 2, the present embodiment are a kind of 4G electric power terminal DTU, are realized current electric power terminal
2G system be converted into 4G communication Internet of Things wireless router.As shown in Figure 1, in addition to including in 4G electric power terminal DTU terminal
Ethernet nic, RS485 communication interface, microprocessor, clock, power supply, LED including being connect with electric power terminal by cable are aobvious
Show that other than device etc. further include 4G network interface, realizes that Ethernet card interface connects with 4G network under the control of the microprocessor
The module and realize the module that RS485 interface and 4G network interface are mutually converted that mouth is mutually converted, there is the two modules, so that it may
Realize current electric power terminal and 4G network interface.
In the present embodiment, MCU, which is used, has independent intellectual property right, RISC instruction framework, technical grade 32 C0 kernels
Processor, maximum operational speed 48MHZ, built-in independent WDG guarantee the reliable and stable operation of system.Specific MCU uses 32bit
C0 kernel processor, 128KFlash, 8KSRAM, the operating rate of 48MHZ, 1 SPI, 3 UART ports, QFN48 encapsulation,
Give uplink assignment one GPIO, downlink Ethernet and RS485 respectively distribute a UART port, distribute a LED 7 GPIO mouthfuls and show
Show.
Technical grade power management chip provides a system to reliable and stable power supply.CLOCK is supplied to MCU continuous-stable
Clock guarantees that system can be with the operation of continuous-stable.The Ethernet chip of technical grade supports 10M/100M to adapt to automatically.Specifically
, ethernet segment is that (CH395Q is the ether of a superelevation cost performance, built in hardware ICP/IP protocol stack by CH395Q chip
Network Communication chip), network transformer, RJ45 interface composition.It supports a server-side that can connect multiple client simultaneously, is
The multiple electric power terminals of DTU connection provide possibility.Furthermore DTU connects as server-side, electric power terminal as client in system
