Abstract
The invention discloses a portable multimedia over coax alliance (MoCA) network tester, which comprises an MoCA terminal and a control part, wherein the control part comprises a liquid crystal display (LCD) screen and a micro control unit (MCU); the LCD screen is in communication with the MCU in an interface mode with serial interfaces, serial peripheral interfaces (SPI) or parallel interfaces; and the MCU is in communication with the MoCA terminal through the serial interfaces or network interfaces. By using the characteristic that MoCA head end codes can be configured into a terminal, and communicating the terminal with a computer through the serial interfaces or the network interfaces, a function of checking the own information of the terminal is realized, and the same function is realized by simulating the computer in a combination mode of the MCU and the LCD screen. The portable MoCA network tester has the advantages of portability, convenience for test, and the like; all relevant parameters of an MoCA network can be tested; the problem of no special instrument for test of the MoCA network can be effectively solved; and further popularization of MoCA products is facilitated.
Description
Technical field
The present invention relates to a kind of MoCA network tester.
Background technology
Along with MoCA is extensively applied to broadcasting and TV EOC network as access technology, and paid close attention to by increasing radio and TV operator.But,, also do not have a kind of network testing instrument of special use to assist the broadcasting and TV workmen to construct or the investigation of network failure as a kind of emerging technology and utilization.
At present the broadcasting and TV operator generally is to use conventional instruments such as frequency spectrograph, power meter, can only test some link radio-frequency informations, such as link attenuation, noise situations, can only obtain through the information of checking the MoCA head end for the whole service state of MoCA system.
And when installing terminal in users home or investigation problem; Also must check information to MoCA head end installation site; And the installation site of head end makes the installation and maintenance personnel operation extremely inconvenient generally in the place away from the user such as corridor, basement, vertical shaft, field equipment case, and need operate through using equipment such as notebook computer; For general construction team, cause great difficulty for the investigation problem.
Summary of the invention
Technical problem to be solved by this invention provides a kind of portable MoCA network tester, to solve the difficult problem of MoCA network test.
In order to solve above-mentioned technical problem; Technical scheme of the present invention is: a kind of portable MoCA network tester; Comprise MoCA terminal and control section; Control section comprises LCD display and MCU, interface mode and the MCU communication of LCD display through having serial ports, SPI or parallel port, and MCU is through serial ports or network interface and MOCA terminal called.
Said LCD display is connected communication with the MOCA terminal through the serial ports commutation circuit with MCU, MCU.
Because the MoCA standard mainly MoCA solution that provides of the side of drafting U.S. Entropic company has bigger flexibility; He both provided independent terminal solution; Can be compiled into the terminal code through the software arrangements of head end again, and use the hardware of head end to use as the terminal; And can use serial ports or network interface to check the information relevant of reflection MoCA link through modes such as local command line, telnet by means of computer like percentage modulation physical layer rate, packet loss etc.
Utilize this principle; The present invention is through being configured to the terminal to the MoCA head end, and increases microprocessor MCU and LCD liquid crystal display screen, selects the parameter that will check through the push-botton operation menu; Then through microprocessor MCU MoCA terminal called therewith, obtain relevant data and be presented on the liquid crystal display screen; And use the rechargeable battery that can reuse to originate, can be convenient for carrying use as the power supply of entire equipment.
Use this device to test at user node (position at installing M oCA terminal); Can check conveniently that user node is to indexs such as the link attenuation of MoCA head end, noise condition; And can check all important indicators of relevant MoCA such as percentage modulation carrier-to-noise ratio, physical layer rate, packet loss, numeral and the simulation focusing system in the MoCA work; And can in time locate the problem that in use possibly occur, handle for the attendant.
For being used to investigate network problem, can be installed in user node to this device to each network node between the MoCA head end easily, carry out network segmentation investigation, and needn't worry that ground such as corridor, basement field do not have the problem that power supply can not connection device.
The present invention is by means of the characteristics at the configurable one-tenth of MoCA head end code terminal, and utilizes this terminal and computer expert to cross serial ports or network interface communication, and the function that can check this terminal self information adopts MCU+LCD display screen analogue computer to realize identical function.Have advantages such as portable, convenient test, can test all relevant parameters of MoCA network, can effectively solve the problem that present MoCA network test does not have instrumentation, help the further popularization of MoCA product.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is principle of the invention figure.
Fig. 2 is an embodiment of the invention schematic diagram.
Embodiment
As shown in Figure 1, the present invention includes MoCA terminal and control section.MoCA terminal part hardware is identical with MoCA head end scheme commonly used at present, is configured to terminal pattern to it through configuration.
Control section comprises microprocessor MCU, LCD display, power supply etc. and partly forms.The communication at MCU and MOCA terminal can be selected serial ports or network interface; LCD display can select to have interface mode and MCU communications such as serial ports, SPI or parallel port.
Selected the display screen of serial communication among Fig. 2 for use, control section and MoCA terminal part adopt the serial communication mode, through the serial ports commutation circuit control MCU respectively with MoCA terminal, LCD display communication.
As shown in Figure 2, SW is the output pin of MCU, is used to control the forwarding of serial ports; TX and RX are respectively serial ports output and the input pin of MCU; RXLCD and TXLCD are respectively the input and output pin of LCD display serial ports; RXMOCA and TXMOCA are respectively the input and output pin of the serial ports of CPU on the MoCA terminal.Concrete implementation procedure is following:
1.MCU test button, judgement need to show any information;
2.MCU be changed to high level to SW, at this moment serial ports tangential and MoCA terminal called;
3.MCU, send acch x or clnkstat x (x is corresponding to the parameter of wanting displaying contents in these two orders) to the MoCA terminal according to wanting content displayed, for example to show information transfer system, then send the clnkstat-a order;
4. wait for MoCA terminal return information;
5. after receiving the information of returning at the MoCA terminal, carry out data extract;
6. be changed to low level to SW, this moment, serial ports tangential and LCD display communication wanting content displayed to send to LCD display, let it show;
7. carry out 3～6 step refresh datas, and judged whether that button is pressed and require to show other guide.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
