The implementation process of a kind of electric energy meter data intelligence read-write equipment based on bluetooth communication of this utility model is:
S1. intelligent mobile terminal is connected with bluetooth transparent transmission module bluetooth communication, main control unit and described bluetooth transparent transmission mould
Block, peripheral communication module serial communication connect, peripheral communication module communication module physical connection corresponding with electric energy meter；
S2. the application module on intelligent mobile terminal sends electric energy meter digital independent to bluetooth transparent transmission module or arranges finger
Order；After bluetooth transparent transmission module receives the reading of described ammeter data or arranges instruction, send in electric energy meter data to main control unit
Pass request；Described electric energy meter data upload requests is transmitted to peripheral communication module by main control unit；Peripheral communication module is by described
Electric energy meter data upload requests is sent to electric energy meter；
S3., after electric energy meter receives described electric energy meter data upload requests, communication module returns data recovery information to the periphery,
Data recovery information is transmitted to main control unit by peripheral communication module, and main control unit sends described data to bluetooth transparent transmission module and returns
Complex information, the application module that described data recovery information is sent on intelligent mobile terminal by bluetooth transparent transmission module.
In the present embodiment, as shown in Figure 2,3, intelligent mobile terminal (mobile phone) and bluetooth transparent transmission module BLE are completed
Bluetooth connects, and after bluetooth transparent transmission module BLE is connected with the serial ports of main control unit MCU, triggers the enable of main control unit MCU with button
End EN, presses the triggering button triggered in key circuit for the first time, and main control unit MCU detects in trailing edge and has no progeny, and closedown removes
Other outside trailing edge own interrupts interrupt, and press triggering button again, and main control unit will be connected with bluetooth transparent transmission module
Enable pin EN to set low；When enabling pin EN and setting low (for low level), bluetooth transparent transmission module BLE can start at certain intervals
Broadcast, until docking successfully with mobile phone, when enabling pin EN and being high level, bluetooth transparent transmission module BLE is in shape of sleeping completely
State；When enabling pin EN saltus step from low to high, no matter which kind of state is module be in, sleep state can be immediately entered.
When after successful connection, as it is shown in figure 5, the present embodiment is by the delivery outlet that can regularly overturn of bluetooth transparent transmission module BLE
LED1, LED2 be connected indication LED lamp and wake up up indication LED lamp connect, display bluetooth transparent transmission module BLE and mobile phone be in connection
State.The physical pins of bluetooth transparent transmission module BLE and main control unit MCU connects as shown in Figure 4, after successful connection, and can be from TX
Be given " TTM:OK r n 0 " word string, main control unit MCU can determine whether normally to forward behaviour according to this word string
Make；
After connecting and actively being disconnected by mobile phone A PP end, can be given from TX " TTM:DISCONNET r n 0 " word string prompting,
If improper disconnection, can be given from TX " TTM:DISCONNETFORTIMEOUT r n 0 " word string prompting.
After successful connection, ammeter data just can be read out or arrange by mobile phone A PP.Mobile phone A pp sends and reads
Or instruction is set, after bluetooth transparent transmission module BLE receives this instruction, send electric energy meter data upload requests to main control unit MCU,
Bluetooth transparent transmission module BLE can set low 15BCTS pin, can start the soonest to send at 16TX pin after 500us, until electric energy
Table data request last time is sent.Forward delay interval can be configured by AT instruction.Electric energy meter data upload requests sends
Complete, 15BCTS pin can be set high by bluetooth transparent transmission module BLE.Main control unit MCU receives the electricity from bluetooth transparent transmission module BLE
Energy table data upload requests, forwards the request to peripheral communication module, is last transmitted to electric energy meter.
DL/T645 agreement followed by electric energy meter, after receiving the instruction reading or arranging data, needs to reply data or mistake etc.
Information, main control unit MCU receives data recovery information and is transmitted to bluetooth transparent transmission module BLE, when main control unit MCU has data recovery
Information sends to bluetooth transparent transmission module BLE, need to be dragged down by 16BRTS pin, and main control unit MCU can start to send after about 100us
Data recovery information；After being sent, main control unit MCU answers Active elevation 16BRTS pin, allows bluetooth transparent transmission module BLE move back
Go out serial ports and receive pattern.It should be noted that PLSCONFM serial data is sent completely before raising 16BRTS pin, otherwise can
Censored Data phenomenon occurs.If the 16BRTS pin of main control unit MCU is always maintained at low level, then bluetooth transparent transmission module BLE
Serial ports can be constantly in and receive pattern, result in higher power consumption.
In process of data communication, it is significant to note that bluetooth transparent transmission module BLE support serial ports hardware protocol and
The serial port protocol of electric energy meter difference, therefore main control unit MCU is also responsible for the important task of unified serial port protocol.Main control unit MCU
AT instruction can be used to arrange different baud rates and bluetooth transparent transmission module BLE communication, and main control unit MCU is optional to be led to electric energy meter
The serial port setting of news, being 7 or 8 as can be arrange serial ports sent data bit, can set check bit, no parity check position, even parity check, strange school
Test, 1 stop position, and communication baud rate is set.So, main control unit MCU is receiving the electricity that bluetooth transparent transmission module BLE sends
During the data recovery information that energy table data upload requests and electric energy meter send, the data message received is carried out protocol conversion, so
After retransmit away, it is ensured that being properly received and resolving of data.
Above disclosed only preferred embodiment of the present utility model, it is impossible to limit right of the present utility model with this
Protection domain, the equivalent variations therefore made according to this utility model claim, still belong to the model that this utility model is contained
Enclose.
