Divide the safety for considering that the semaphore of Current traffic whistle control system is connected with traffic police control centre and monitoring center.Current letter
Number machine with traffic police control centre networking generally in such a way that interchanger is directly connected to, if LAN there are network storm,
It is be easy to cause semaphore program operation exception, influences crossing traffic control, simultaneously because the reasons such as construction, Network Abnormal can also be made
The case where can not accessing control centre in for a period of time at part signal machine；Meanwhile for semaphore producer, also it is badly in need of solution
The problem of certainly monitoring intersection annunciator equipment operation condition in real time, since semaphore may be generally laid out in the arbitrary city in the whole nation
City is only monitored by way of Wireless Networking, currently to the solution of Wireless Networking joint control generally directly by 4G
Transmission module is connected to semaphore, and this method need to change semaphore hardware and update semaphore program, increase the hard of semaphore
Part and human cost；Semaphore directly increases WiFi wireless devices and is also easy traffic police control centre private network being exposed on public network,
Influence the safety of traffic police control centre private network.
Utility model content
The purpose of this utility model is to provide a kind of semaphore network communication devices, and it is relevant various to realize semaphore
Network communication and security mechanism processing, improve intelligence and the operational reliability of semaphore.
To achieve the above object, the utility model uses following technical scheme：Including main control module, the main control module
It is the AccessPort processing circuit that is connect including data processing circuit and with data processing circuit, WIFI processing modules, first wireless
Transceiver module, the second radio receiving transmitting module, the first network interface processing monitoring circuit and the second network interface processing monitoring circuit, the WIFI
Processing module is wirelessly connected by WIFI and handheld terminal, and the second network interface processing monitoring circuit passes through Ethernet interface and signal
Machine connects, and first radio receiving transmitting module is connect by 4G networks with O＆M monitoring center, second radio receiving transmitting module
It is connect with traffic police control centre by 4G networks and the first network interface processing monitoring circuit, the AccessPort processing circuit and serial ports
Communication interface connects.
As a further improvement of the above technical scheme：
The data processing circuit uses the core board of model MC-335.
As shown from the above technical solution, the utility model realizes signal by the design of semaphore network communication module
The safety-optimized processing of machine wire and wireless networking joint control function, solves possibility security implication of the wireless public network to semaphore.It is logical
The private network processing based on route pattern is crossed, the security isolation management of wireless public network and traffic police's private network is realized, solves wireless public affairs
The problem of net may cause safety to reduce traffic police's private network, and further improve between traffic police's private network and semaphore and be
System safety, the equipment safety is reliable, and convenient for extension, application is high.
Description of the drawings
Fig. 1 is the circuit block diagram of the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, the semaphore network communication device of the present embodiment, including main control module 1, main control module 1 include number
According to processing circuit 11 and the AccessPort processing circuit 12 being connect with data processing circuit 11, WIFI processing modules 18, the first nothing
Line transceiver module 14, the second radio receiving transmitting module 15, the first network interface processing monitoring circuit 16 and the second network interface processing monitoring circuit
17, WIFI processing modules 18 are wirelessly connected by WIFI and handheld terminal, and the second network interface processing monitoring circuit 17 passes through Ethernet
Mouth is connect with semaphore, and the first radio receiving transmitting module 14 is connect by 4G networks with O＆M monitoring center, the second wireless receiving and dispatching mould
Block 15 by 4G networks and the first network interface processing monitoring circuit 16 connect with traffic police control centre, AccessPort processing circuit 12 and
Serial communication interface connects.
Operation principle：In the present embodiment, data processing circuit 11 is using the core board of model MC-335, core board tool
There are 2 road network interfaces, it can external 2 road ethernet communication；1 road MINI-PCIE interfaces are used to connect 4G communication modules, 2 road USB connect
The 4G and WIFI module of mouth connection USB interface；Core board dominant frequency 800MHz can meet the various calculation processings of network communication device
Function.
Radio receiving transmitting module 14 is realized and is supervised with O＆M using the ME909S-821 wireless modules of Huawei's MINI-PCIE interfaces
The data interaction function at control center, since the wireless network is in 4G public networks, core board when handling the wireless communication module,
Only transmission of the permissible semaphore information to O＆M monitoring center does not receive any data of 4G networks, has ensured that semaphore
Safety.Network interface processing monitoring circuit 17 realizes network using ethernet PHY interface chip DP83848 adaptive 10/100M
The network connection of communication device and semaphore.
Network processes monitor circuit 16 and monitor 17 identical circuit chip of circuit using with network processes, realize and are controlled with traffic police
