Embodiment
For making to have a better understanding and awareness architectural feature of the present invention and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 1, a kind of ammeter data collector possessing infrared upgrade function of the present invention, comprise main control module 1, main control module 1 adopts uPD78F0526 processor, for controlling whole collector and calculating.Also comprise storer 5, RS485 communication module 3 and infrared transceiver module 2, storer 5 stores for data and program, and RS485 communication module 3, for the connection between collector and outside ammeter, can obtain the data on outside ammeter.Infrared transceiver module 2 is for the communication between infrared palm machine 7 and main control module 1, and infrared palm machine 7 and main control module 1 can transceiving datas in infrared allowed band.
RS485 communication module 3 is connected with main control module 1, and the other end of RS485 communication module 3 is connected with outside ammeter, sends the data of outside ammeter to main control module 1.Storer 5 is connected with main control module 1 by I2C bus, uses I2C bus can complete transmission work reliably, fast.Infrared transceiver module 2 is connected with data output end with the data input pin of main control module 1 respectively, and infrared transceiver module 2 and infrared palm machine 7 carry out wireless infrared transmitting, can carry out wireless data input and output with infrared palm machine 7.
Carrier module 6 is for the carrier processing of signal, and carrier module 6 is connected with the signal output part of main control module 1, and the other end of carrier module 6 is connected with power circuit.The ammeter data that main control module 1 is collected by RS485 communication module 3 on power circuit, utilizes power circuit to reach system terminal by carrier module 6 carrier wave.Power module 4 is for powering to whole collector, and power module 4 is connected with infrared transceiver module 2 with main control module 1, carrier module 6, storer 5, RS485 communication module 3 respectively.Power taking is by after transformer pressure-reducing, rectifier rectification, capacitor filtering from line of electric force for power module 4, and access three-terminal voltage-stabilizing feed regulator isolator (78L05) is that+5V voltage supply whole system uses after adjustment.
The invention provides the infrared upgrade method that a kind of dependence possesses the ammeter data collector of infrared upgrade function, comprise the following steps:
The first step, is placed in infrared palm machine 7 within the scope of the Infrared Transmission of infrared transceiver module 2, utilizes the method for prior art to set up with infrared transceiver module 2 and communicates.Infrared palm machine 7 is by ROMPaq framing composition upgrading message, and multiple Frame forms upgrading message.Upgrading message is sent to infrared transceiver module 2 by wireless infrared transmitting by infrared palm machine 7.
Second step, the upgrading message received is passed to main control module 1 by infrared transceiver module 2, and main control module 1 reads the upgrading message that infrared transceiver module 2 receives.Upgrading message is resolved and validation verification it according to frame number by main control module 1, first carries out the sequence of frame number, then resolves to upgrade data, finally verify validity.If it is invalid to verify, the corrupted data that there is Receiver Problem and cause is described in data transmission procedure, the upgrading message damaged is deleted, again receive upgrading message from infrared palm machine 7 by infrared transceiver module 2.If upgrade data effectively, is then write in the corresponding stored unit of storer 5 by main control module 1 by checking.
3rd step, after all frames have all issued, main control module 1 has checked the integrality of the upgrading frame in storer 5, judges in transport process, whether have the Frame do not transmitted.If imperfect, main control module 1 record lacks the frame number of frame, owing to sorting to frame number in second step, directly can find out the frame number of lacked frame.By infrared transceiver module 2, the frame number lacking frame is sent to infrared palm machine 7, require that infrared palm machine 7 is reissued and lack frame.
4th step, the frame lacked is sent to infrared transceiver module 2 by infrared palm machine 7 again, the frame that infrared transceiver module 2 sends to main control module 1 polishing to lack, and the transmission that the ROMPaq now in storer 5 is complete terminates.
5th step, main control module 1 carries out reset operation, and the Bootloader started in main control module 1 checks the legitimacy of application area and upgrading district program, determines whether ROMPaq.
If upgrading district does not conform to rule and abandons updating operation, present procedure version, without the need to upgrading, proceeds to application area and performs.If upgrading district is legal, ROMPaq, ROMPaq terminates the ROMPaq in rear deletion storer 5, prevents program to be again upgraded, and completes a program upgrade.When reality uses, broadcast in infrared palm machine 7 pairs of infra-red range can be utilized to issue ROMPaq, and multiple infrared transceiver module 2 receives laggard line program upgrading processing, can realize the program upgrade of batch to ammeter data collector with this.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and instructions; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
