Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a method and device for automatically controlling and displaying CIU display items. Background Art

[0002] As a portable reading device for smart meters, the Customer Interface Unit (CIU) is often used to read relevant information from the corresponding meter and display it in a loop. With the continuous development of smart meters, users have increasingly higher requirements for the integrated functions of smart meters. Users are not only concerned with data information such as meter balance, relay status, current voltage, and recharge records, but often also want to understand the current meter status, alarm information, etc. Since meters are generally not easy to access, the CIU has become an important tool for users to understand current meter information. Different users often have different requirements for the display of meter data information, which also poses a higher challenge to the automatic display of CIU display items.

[0003] At present, in order to meet the needs of users to observe multiple power data through CIU, Solution 1 adopts a method of corresponding one short code to one or more data IDs. Each data ID corresponds to related power data, such as ID1 corresponds to voltage and current, ID2 corresponds to the power theft alarm status, etc., and multiple power data can be set under each ID. When new data content needs to be displayed, it is often necessary to add a new data ID or add new display data under a certain ID. This usually involves adding new short code content and protocol content. The final result often requires updating the meter or CIU program. Although the software change is simple, it involves upgrading the program in the hands of the customer, which is a serious test for both cost and product reputation. And because each market demand is different, over time, each change in the display item content requires changing the corresponding protocol and related protocol processing code, which is not conducive to later maintenance; Solution 2 reserves a large number of related meter parameter display contents in the CIU cyclic display list in advance, and these display contents are configurable. When the user has new display content requirements, they can set them through the corresponding host computer and other tools to add or delete display items. In this way, the addition or deletion of display items can only be reflected in the cyclic display list, and changes in the content displayed by other short codes cannot be processed. In addition, if there is a new data display item, but the data is not reserved in the cyclic display list, the relevant program still needs to be modified, and the operation is complicated. Therefore, it is urgent to propose a method and device for automatically controlling the display of CIU display items to solve the technical problems of the existing CIU display items being not convenient to add or delete and having poor versatility. Summary of the Invention

[0004] The main purpose of the present invention is to provide a method and device for automatically controlling the display of CIU display items, aiming to solve the technical problems of the existing CIU display items being inconvenient to add or delete and having poor versatility.

[0005] To achieve the above object, the present invention provides a method for automatically controlling the display of CIU display items, comprising the following steps:

[0006] S1, the meter end and the CIU end communicate and match;

[0007] S2. The meter terminal converts the collected meter data into display items, calculates the number of display screens for the display items, and frames the display items before uploading them to the CIU terminal;

[0008] S3. Initialize the display area of the CIU end. The CIU end parses the display items uploaded by the meter end and updates the display area accordingly for display.

[0009] In one preferred solution, the communication matching between the meter end and the CIU end in step S1 is specifically as follows:

[0010] The meter end and the CIU end communicate and match via an agreed data protocol.

[0011] In one preferred solution, the communication between the meter terminal and the CIU terminal in step S1 includes:

[0012] The meter terminal actively pushes meter data to the CIU terminal regularly or irregularly.

[0013] In one preferred solution, the communication between the meter terminal and the CIU terminal in step S1 includes:

[0014] The CIU terminal actively sends an acquisition instruction, which is then counted by the meter terminal and uploaded to the CIU terminal.

[0015] One of the preferred solutions, after calculating the number of display screens of the display item in step S2, further includes:

[0016] Comparing the number of display screens of the display item with a screen number threshold;

[0017] If the number of display screens of the display item is less than or equal to the screen number threshold, the single frame is uploaded to the CIU end;

[0018] If the number of display screens of the display item is greater than the screen number threshold, the display item is uploaded to the CIU end at frame intervals.

[0019] In one of the preferred solutions, the screen number threshold is the maximum number of screens that can be accommodated in one frame.

[0020] One of the preferred solutions, after calculating the number of display screens of the display item in step S2, further includes:

[0021] The meter end defines a unified data format, unit, decimal places, status symbol display control, LED light status, alarm status, screen switching interval and number of display screens for display items. Multiple display items are combined into frames and uploaded to the CIU end using a single frame or frame interval.

[0022] In one of the preferred solutions, the display area of the CIU terminal includes a main display area, a sub-display area, a decimal point area, a symbol area, a unit area, an alarm area and a screen switching interval area.

[0023] A CIU display item automatic control display device comprises: a meter end and a CIU end;

[0024] The meter terminal is communicatively connected with the CIU terminal;

[0025] The meter terminal is used to collect and process meter data and then upload it to the CIU terminal;

[0026] The CIU terminal is used to display the meter data uploaded by the meter terminal in different zones.

[0027] In the above-mentioned technical solution of the present invention, the method for automatically controlling and displaying CIU display items includes the following steps: the meter terminal communicates and matches with the CIU terminal; the meter terminal converts collected meter data into display items, calculates the number of display screens for the display items, and uploads the display items to the CIU terminal; initializes the display area of the CIU terminal, and the CIU terminal parses the display items uploaded by the meter terminal and updates them to the display area for display. The present invention converts meter data into display items and calculates the number of display screens for the display items, and then displays them accordingly on the CIU terminal, thereby making it easier to add or delete CIU display content.

[0028] In the present invention, display items with a unified format defined are uploaded to the CIU end in a single frame or multiple frame intervals through the meter end, and a main display area, a sub-display area, a decimal point area, a symbol area, a unit area, an alarm area, and a screen switching interval area are respectively set on the CIU end to display the display items uploaded by the meter end. In this way, the CIU end can normally display the corresponding data, respond to the alarm information, and control the screen switching interval even if the number and content of the power data are not clear, thereby improving the compatibility and simplicity of the CIU end.

[0029] In the present invention, the screen switching interval or display duration can be displayed in real time through the screen switching interval area. BRIEF DESCRIPTION OF THE DRAWINGS
