Host computer of the present invention receives the data program process flow diagram as shown in figure 11.In Fig. 6 (a) lining input front end processor IP address, click " beginning communication " button, host computer will connect the embedded server (front end processor) in a distant place by the Internet, if successful connection, then front end processor sends response character " Q " to host computer, and front end processor is responsible for the task of data relay always afterwards.After host computer is received response character, learn the network successful connection, just enable communication clock, send command character " A " to slave computer per 0.5 second in timer interrupts.Slave computer sends the 16 system character 0xEE that beginning is transmitted in an expression toward host computer earlier after receiving order, begin to send each 2 byte such as three-phase voltage value (A, B, C), three-phase electricity flow valuve (A, B, C), three-phase phase poor (AB, BC, CA), generator active power, generator reactive power, frequency values, generator power factor, field voltage value, exciting current value, exciting power value then, 1 byte of system failure sign indicating number, the valid data of 33 bytes altogether.Transmit 16 system character 0xDD of an expression end of transmission (EOT) then.Comprise end to end totally 35 bytes.Host computer was promptly asked for a secondary data to a slave computer transmission command character " A " in per 0.5 second, thereby realized the dynamic demonstration of motor status.Do not receive response character " Q " if surpass certain hour, the expression network is obstructed, and system will point out the customer inspection network to connect.
Because the DSP serial communication can only send the integer data, and the host computer video data only requires and keeps a decimal, forces conversion to become integer after 4 so will move to left the floating type data, reduction of data returned in host computer again.Host computer is set to the scale-of-two receiving mode, when host computer is received the data that slave computer sends, carries out following steps, as shown in figure 12:
Step 1: when the data arrival event appears in the WinSock control, judge at first whether 35 data are arranged in the send buffer, just read out data are disposable if any, be placed in the BYTE type array, otherwise continue to wait for next reception incident;
Step 2: the following synthetic double precision datum of number that is designated as odd number (most-significant bytes of data) and is designated as even number (least-significant bytes of data) down adjacent in the BYTE type array is reduced to original data divided by 16 then;
Step 3: each data presentation in text box separately, is kept a position effective digital, if exceed standard value, font color can become redness;
Step 4: the handling failure sign indicating number, the fault that analytic system occurs, if fault, corresponding pilot lamp flicker also has buzzer to report to the police;
Step 5:, then on the interface of Fig. 4 (b), show curve if require to draw voltage, electric current performance graph;
Step 6: under slave computer is uploaded, before the secondary data, the fault of these various data, current date and time, motor ruuning situation and appearance is kept in the ACCESS database file, in order to inquire about or draw history curve afterwards.
System failure sign indicating number is 8 binary codes, is exactly one 8 character variable in slave computer, is initialized as 0, if system detects fault, just adds corresponding fault value on this variable.Whether the first bit representation phase sequence is correct, if just add 1; Whether second bit representation phase shortage, if just add 2; The whether overvoltage of the 3rd bit representation is if just add 4; Whether the 4th bit representation overcurrent, if just add 8; Whether the 5th bit representation underfrequency, if just add 16; Whether frequency is too high for the 6th bit representation, if just add 32; Whether insulation resistance is little for the 7th bit representation, if just add 64; Whether the 8th bit representation controls the protection combined fault, if just add 128.Host computer receives diagnostic trouble code, just can be according to the definition in the agreement, and judgement is what fault to have occurred.

Step 5:, then on the interface of host computer, show curve if require to draw voltage, electric current performance graph;
Step 6: under slave computer is uploaded, before the secondary data, the fault of these various data, current date and time, motor ruuning situation and appearance is kept in the ACCESS database file, in order to inquire about or draw history curve afterwards.
