Embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1, be applicable to that the collector of copying and accepting that the low-voltage power carrier electric energy meter is checked meter comprises single-chip microcomputer 2, storer 5, communication interface 4 and carrier wave receiving circuit 1 and carrier wave transtation mission circuit 3.The single-chip microcomputer model is PL3106, and described type of memory is EEPRom, and described communication interface type is RS485; Single-chip microcomputer 2 one ports are connecting storer 5, and the another port is connecting communication interface 4, and its other two ports are connecting carrier wave receiving circuit 1 and carrier wave transtation mission circuit 3 respectively.

Single-chip microcomputer 2 communicates with concentrator by carrier wave transtation mission circuit 3 and carrier wave receiving circuit 1, transmits the electric energy meter data that collector is read, and perhaps receives the parameter that concentrator is sent.Single-chip microcomputer 2 is according to the parameter of setting of checking meter, the time of setting then, communicate by RS485 communication interface and electric energy meter, read the electricity consumption data; And be stored in EEPRom storer 5.Collector is provided with carrier communication pilot lamp and RS485 pilot lamp in addition, is used to indicate communications status.

As seen from Figure 2, initialization module: be used to finish initialization to single-chip microcomputer, the initialization of EEPRom storer, electric energy meter communication module: be used to finish data read to electric energy meter, carrier communication module: be used to finish response, data memory module: be used to preserve the electric energy meter data that read to concentrator.

Main program flow is seen Fig. 2, and step 10 is to begin action, is step 11 then, finish the initialization of single-chip microcomputer, EEPRom storer etc., enter step 12 then, judge whether to receive the carrier wave message, if, then enter step 13, carry out carrier communication and handle, if not, then return step 12.

The initialization flow process is seen Fig. 3; Step 20 is to begin action, is step 21 then, and step 21 is at first closed interruption, enter step 22 then, finish initialization, enter step 23 then real-time clock, finish initialization to timer, enter step 24 then, carrier communication module is entered initialization, enter step 25 then, to the EEPRom initialize memory, after all hardware initialization is finished, enter step 26 then and open interruption, enter step 27 at last and return master routine.

Timer interrupts flow process, sees Fig. 4; In interrupting, timer finishes reading to the electric energy meter data.Step 30 is to begin action, enters step 31 then, judges whether the time of checking meter of setting has arrived, if then enter step 32, if not, then directly withdraws from interruption, returns master routine.Step 32 is closed interruption, enters step 33 then, sends out communication message and gives electric energy meter, reads the electric energy meter data, enters step 34 then, judges whether electric energy meter has response data, if, then enter step 35, if not, then enter step 36.The electric energy meter data that step 35 is read are preserved, and enter step 36 then, and whether judgment data is copied and accepted and finished, if enter step 37; If not, then return step 33, continue to copy and accept.Step 37 judges whether all ammeters are copied and accepted and finishes, if, then enter step 38, if not, then enter step 33, copied and accepted all ammeters.Step 38 is opened interruption, enters step 39, returns master routine.

The carrier communication flow process is seen Fig. 5; Step 50 is to begin action, enters step 51 then, judges whether the message that receives is correct, if, enter step 52, if not, then enter step 57, directly return.Step 52 judges whether message is to mail to this machine, if, then enter step 53, if not, then enter step 57, directly return.Step 53 judges whether message is relay messages, if, then enter step 55, adjust the trunk information of message, message is sent once more.If not, enter step 54, message is analyzed, and carry out corresponding order according to message, enter step 56 then, the message that sends execution result is to concentrator.Enter step 57 then, return master routine.
