In a preferred embodiment of the present invention, when judging whether decoded decoded data satisfies predetermined device replied rate, can determine first the Frame number Y of home bus system device replied, determine device replied rate U:U=Y/X according to following formula again, wherein, the Frame number of X for calling the roll, as device replied rate U during more than or equal to predetermined device replied rate, determine that test result is qualified, otherwise, determine that test result is defective.
In actual applications, HBS equipment can comprise the various electric equipments that can be applied to HBS, for example: air-conditioning.Certainly, also can adopt above-mentioned bus data method of testing fully for the HSB system that comprises various household electrical appliance.
Be described in detail below in conjunction with Fig. 2 and preferred embodiment bus data method of testing to above-mentioned home bus system.
Fig. 2 is the bus data test flow chart of according to the preferred embodiment of the invention HBS, and as shown in Figure 2, this flow process mainly may further comprise the steps: (step S202-step S212):
Step S202, (for example use the transducer of computer USB mouth by a HBS/USB, in actual applications, can use the chip of ARM company, this chip possess data are transformed into the computer network of supporting USB from the HBS system) in scheduled duration (for example, in the present embodiment, scheduled duration is 24 hours) the interior data (data in 24 hours, i.e. above-mentioned initial data) that receive from the bus of HBS system;
In actual applications, the transducer of HBS/USB can also be transformed into the HBS signal with 232 signals, and the baud rate of HBS signal can be supported 57600bit/s, and the baud rate of usb signal can be supported 38400bit/s.
The initial data (data in namely 24 hours) that step S204, importing receive;
In actual applications, the method fully can be on the special-purpose software of good each section working procedure of centralized configuration in advance (for example, each section working procedure can be concentrated and become a kind of labview software), Once you begin receive initial data, namely initial data is preserved and is imported to software inhouse in real time, for next step initial data is resolved and prepares.
Step S206, initial data is carried out decision operation and decode operation;
In actual applications, if detect the initial data that to decode, the data that can can't decode are presented on the display interface of host computer (being in charge of all HBS equipment) in real time, like this, these initial data that can't decode just can tested personnel be found at any time, in order to according to actual conditions each device or equipment in the HBS system are adjusted, are adjusted again and need not all to finish all test conditions.
The data (being decoded data) behind the decode operation are carried out in step S208, acquisition;
Step S210A, detect the initial data that to decode in the initial data in 24 hours, and judgement HBS bus data error rate (namely according to formula: the number of the number/initial data of the initial data that can not decode obtains), if error rate reaches more than 5% (being the predetermined bus data error rate), the accuracy of then judging the data in the bus is excessively low, thereby determine that result of determination is defective, otherwise, then judge the accuracy of the data in the bus as normal, thereby determine that result of determination is qualified.
Step S210B, judge whether the application layer sequential of the decoded data in 24 hours is correct, if the application layer sequential of all initial data is all correct, then the display interface at host computer shows " sequential is normal ", otherwise wrong place appears in display application layer sequential on the display interface of host computer;
In actual applications, can be in advance all application layer sequential of the initial data on the HBS bus be integrated in the Rule of judgment such as above-mentioned labview software, with the sequential criterion of these application layer sequential as the initial data on the bus.
Step S210C, judge whether the decoded data in 24 hours meets the application layer protocol of HBS bus, do not reach 5% if meet the decoded data of application layer protocol, then judge the data exception in the HBS bus, otherwise, judge that the data in the HBS bus are normal;
In actual applications, can be integrated into the application layer protocol form of the initial data on the HBS bus in the judgement such as above-mentioned labview software, software will automatically extract the data that do not meet the application layer protocol form in the bus data (comprising: disconnected frame, mess code, check errors) and preserve.
Step S210D, judge the device replied rate corresponding to the various HBS equipment of decoded data in 24 hours, if the response rate of each HBS equipment reaches more than 95%, then judge data on the HBS bus as normal, otherwise, judges that data on the HBS bus are as unusually;
Step S212, gather the result of determination in each stage, with final judgment result displays on the display plane of host computer.
Below in conjunction with specific embodiment the interface that each result of determination shows is described.
Halfhour data instance with the HBS bus, initial data is imported labview software, the data length that software will calculate internal bus half an hour is N:N=929114, the data that can not decode are M:M=30000, the data of decoding are T:T=899114, show decoded data T, can not decoded data M and the result of calculation P:P=M/N=3% of bus data error rate.
