Four-Faith WIFI advertising system comprehensive coverage the Buses in Fuzhou

Recently, the Ministry of Transport issued " on accelerating the second batch of urban public transport intelligent application demonstration projects relating to the matter ," which was selected second batch of Fuzhou Public Transport Intelligent demonstration cities.

With the drive to accelerate the intelligent transportation -related grants and state funds , Fuzhou has begun on the basis of the integration of existing resources , through information, intelligence means to further improve urban public transport enterprises operating scheduling and management efficiency, enhance trade management , decision-making and emergency response capabilities , providing passengers with fast, safe , convenient and comfortable travel services.

Kang Chi new bus company which is Four Faith customer, after test wifi router samples, they give a high evaluation and established a good cooperation with Four-Faith.

At the beginning of this year,the Four Faith with its good brand image and reputation in the intelligent transportation field , becoming the Kang Chi new bus company car WIFI advertising system service provider , currently Four-Faith has provided more than 500 wireless communication devices help Fuzhou Bus WIFI coverage projects construction .

​

Fuzhou wireless 4G/3G/2.5G network covering more perfect degree , Four-Faith -board WIFI installed in the bus advertising system , you can achieve a better Wi-Fi access experience, while local storage terminal entertainment , advertising push and monitoring and other aspects of vehicle safety features also can achieve better results. Currently, Fuzhou free bus WIFI still in beta stage , Four-Faith  have been gradually completed vehicle equipment installation and commissioning .

After passengers linked WIFI, will first see the advertising message ; then jumps to the login , registration page , for the first time passengers need to transit through WIFI passengers carry their mobile phone number after registration ( message authentication code ) to log in , the login success You can surf the web after ; already registered for the passengers through the phone number and password login to surf the web .

Reactive Power Compensation wireless Solutions for power distribution network

Part 1  Overview

In the power system, consume large amounts of reactive power devices exist, the use of power system voltage of these devices will generate intense volatility, such as the impact of reactive power load: rolling mill, electric arc furnace, electric railway and so on. At the same time there are users of the system voltage stability has higher precision equipment requirements: such as computers, medical equipment and so on. If the reactive power can not be controlled, it will cause adverse effects on the grid voltage. Also lack of reactive power reserves will lead to lower voltage levels. For these reasons, how quickly and effectively solve the power system reactive shortfall. Has important practical significance. After the installation of reactive power compensation controller in the grid can provide inductive reactance reactive power consumed by reducing the grid to provide power to the inductive load, reactive power delivered by the line, due to the reduction of reactive power flow in the grid, thus reducing transportation lines and transformer reactive power caused by power loss, which is the reactive power compensation. Reactive power compensation can improve the power factor is less investment and quick results in a loss reduction of energy saving measures.

With the development of industrial automation, the original site with a notebook computer or data logger and reactive power compensation controller wired communications and data collection has grown to a remote intelligent monitoring, many must unattended equipment or monitoring point, not suitable to build a wired communication network, with Four-Faith IP Modem (F2114), through existing wireless network intelligence gathering from remote data needed to put together, greatly improving efficiency.

Part 2  Project analysis

2.1 System components

2.1.1 Controller: With RS232 communication interface

​

2.1.2 Transfer Terminal: Transfer terminal uses Four-Faith F2114, permanent online in real time, embedded proprietary TCP / IP protocol stack, transparent transmission, support RS232 and RS485 in parallel.

2.1.3  Center software system: PC software with the controller.

2.2 System architecture

Reactive power compensation controller via RS232 communication interface and Four-Faith IP modem (F2114) connection, remote data center server can use APN ordinary ADSL, leased line or a network access. When F2114 is connected through GPRS network to a remote data center server host, create a transparent data channel, as long as the data controller to generate serial, F2114 will receive the data sent to the intact data center server host; same server commands issued by the host channel after transfer to F2114, F2114 to the controller via serial port, enabling data transmission in transparent way. System topology is shown below:

Part 3  Project framework

3.1 Collection terminal is connected with transmission modem

Four-Faith F2114 wireless transmission modem supports terminal interface that can connect to communication terminal via RS232/485.

F2114 and the collector junction line sequence as follows:

3.2 Wireless data transmission

Transmission equipment using Four-Faith F2114 GPRS modem, which featured, stable performance, easy to use, it is an industrial grade wireless transmission terminal, has been widely used in a variety of industrial and financial applications.

After the terminal equipment and transmission equipment connected, set up a variety of communications parameters, operating mode, fill in the address and data center application port numbers in the transport equipment F2114. So that when data is transmitted to F2114, F2114 will be transparently transmitted the data to data center.

Terminal equipment supports multiple center mode (standby center, multi-center), multiple active mode (telephone, SMS, data), multiple operating modes (TCP, UDP, telnet, etc.), user-friendly networking and various system requirements. Heartbeat mechanism, registration pack mechanisms frame control data, a variety of mechanisms, such as reconnection mechanism to ensure that equipment is not only real-time online, and reliable, and convenient for customers according to the scene to set the various transmission parameters, and thus achieve the best results.

3.3 Data Center Software Platform

Reactive power compensation is a core part of the wireless monitoring system software.

Currently Four-Faith provide such center interface: Serial read the original program, to be compatible with the original system without doing development work, we provide a virtual serial port software (TCP2COM);

TCP2COM software

PC software
