Detailed description of the invention
Fig. 1 is the structural schematic diagram of present invention detection terminal.
Specific embodiment
Detect terminal embodiment:
The detection terminal that the present embodiment proposes, including acquisition module, display module, input module and controller acquire mould
Block, display module and input module are connect with controller respectively.
As shown in Figure 1, display module and input module use same equipment, for display/input module, using multi-point touch
Touch display screen, for input information and display information；In the present embodiment, detects direct setting RS485 in terminal and connect
Mouthful, but it is provided with USB interface, and electric energy meter generally uses RS485 interface, therefore acquisition module is in order to acquire electric energy meter
Data communicate the data of electric energy meter via RS485 including RS485 connection and built-in USB-RS485 signal conversion module
Line, USB-RS485 signal conversion module, USB interface are connected in detection terminal, and acquisition module data collected are transferred to
Controller.Certainly, as other embodiments, display module and input module can not also be same equipment, and display module is logical
It crosses display screen to be shown, input module can be inputted using key form.In addition, acquisition module may be other classes
The communication interface of type, as long as may be implemented to obtain data from electric energy meter.
Controller include memory, processor and storage in memory and the computer journey that can run on a processor
Sequence, processor realize the detection method of electric energy meter when executing computer program.
Central scope of the invention is that electric energy meter detection method is formed by computer program, including two kinds of carriers (or
Two kinds of applications of person), that is to say, that detection terminal of the invention can be a kind of hand-held maintenance terminal, can also be a kind of hand
Hold meter reading terminal.Electric energy meter detection method is introduced by taking hand-held maintenance terminal as an example below.
Electric energy meter detection method, comprising the following steps:
1) table corresponding to the type information and each type of electric energy meter of various electric energy meters is stored in memory first
Read rule and communication protocol in address；Table address reads rule including the visual information on required electric energy meter and to visual
The mode of operation of information can obtain table address in conjunction with visual information and visual information operating method, this is that the hand-held maintenance is whole
Hold the important prerequisite condition of work.
2) after hand-held maintenance terminal is connect with electric energy meter, touch display screen shows the first prompt information, fills out for prompting
Write the type of electric energy meter；Under normal circumstances, the type of electric energy meter includes manufacturer and the model of electric energy meter, and outside electric energy meter
Manufacturer and model are passed through touch by the manufacturer (i.e. producer) and model, testing staff that can all have the electric energy meter on shell
Display screen input, the electric energy meter type that processor is inputted according to the touch display screen detected determine corresponding to the electric energy meter
Table address reads rule and communication protocol.
It is different that the table address of the electric energy meter of different manufacturer's productions, which reads rule, such as: certain producer's electric energy meter
The inverse the 13rd of sequence number to 2 reciprocal totally 12 be the multifunction electric meter table address, it is thus determined that electric energy meter institute is right
After the table address answered reads rule and communication protocol, the communication connection with electric energy meter is established by RS485 connection, post-processing
Device issues request the second prompt information of input.
There are many kinds of communication protocols: such as DL/T614-2007, represents 07 specification；DL/T614-1997 represents 97 specifications；
There are also external specification standards etc..
3) touch display screen shows the second prompt information, fills in the corresponding visual information of the type electric energy meter for prompting；
Under normal circumstances, visual information includes sequence number information, includes the table address of the electric energy meter in sequence number information, for convenience
Testing staff carries out input operation, and when prompt inputs visual information, also prompt is the electric energy from which position to which position to processor
The table address information of table type.
Operator inputs the digit of corresponding sequence number according to the prompt of touch display screen in touch display screen, place
Reason device is obtained according to the sequence number information of the touch display screen input detected using the mode of operation of corresponding sequence number information
Table address.
If touch display screen display communicates successfully, it is correct to prove that the table address of electric energy meter is read, if in setting time,
Communication cannot be effectively established, then touch display screen shows Communications failure.
4) processor parses acquisition module data collected according to table address and communication protocol, and then detects electricity
Whether energy table works normally.
Above-mentioned steps 2) with step 3) in, be the visual information of the type followed by inputing power table of first inputing power table.
As other embodiments, the two steps can input simultaneously, because being stored with the class of various electric energy meters in memory
Table address corresponding to type information and each type of electric energy meter reads rule and communication protocol, processor can be according to institutes
The information of input is searched, and then the data of electric energy meter collected are parsed after foundation and the communication of electric energy meter.
In the present embodiment, visual information includes the table address of electric energy meter, is not limited to only wrap in certain visual information
Table address information is included, may include number or text information that other show on electric energy meter shell.
