How to make an input collection system through EXCEL?

1. There are two schemes to customize the program and import excel data into the background database of the system in batches. The condition is that the system is customized by yourself, otherwise it is generally difficult to achieve. Simulate manual operation and customize programs. Similar to the key elf. The workload of these programs is not low, and it is difficult to provide free service.If it's the second item, you can ask me to do it.

2. For this kind of office system input, we first sort out the external data to be entered, that is, the waybill number here, which can be exported from the Excel file through the vba macro, or directly in TXT notepad format. Then position the mouse cursor into the waybill number editing box to be entered and start entering.

3. Tools-Options-Edit, change "Enter direction" to "to the right". Select the cell area where you need to enter the options. Without any selection, enter the option number with the numeric keypad, press Enter to jump to the right to the next cell, and the end of the line will jump to the first cell of the next line.

4. By making scripts, you can let the key elf replace your hands and automatically perform a series of mouse and keyboard actions.The key sprite is simple and easy to use, and you can make powerful scripts without any programming knowledge. As long as the action can be completed with both hands in front of the computer, the key elf can be replaced.

What are the online automatic collection schemes of energy measurement data?

1. The main components of the acquisition system: special variable acquisition terminal, low-voltage centralized meter reading terminal and electricity meter. The user's electricity data collected by the front-end smart meter is transmitted to the concentrator through the RS48 low-voltage broadband carrier. The concentrator realizes the reuse of narrowband channels, and the upbound data is transmitted to the master station system through the communication channel.

2. The collected data can be used for power system operation management, energy consumption analysis, electricity metering, etc.Octopus Collector is an Internet data collector with comprehensive functions, simple operation and a wide range of applications.

3. Trap, provide an energy measurement data collection method and system that can obtain statistical data in real time and accurately.

What are the collection methods of the data acquisition system and what are the characteristics of each

1. Traditional data source acquisition: This kind of data usually comes from the internal database, logs, files and tables of the enterprise Grid, etc., and external traditional data sources, such as public databases, government reports, statistical data, etc. These data are usually structured data, which is easy to store and process.

2. The data acquisition methods of the software system mainly includeThe following: Manual collection: access web pages or applications one by one through manual operation, and manually copy and paste the data into the local file or database. This method is suitable for small amounts of data or manual screening, but it is less efficient and error-prone.

3. The collection methods of business data include: external data acquisition, network data acquisition, telephone interview, face-to-face interview, field research. External data collection understands market dynamics and competitors by collecting data from external channels, such as industry reports, market surveys, financial statements, news reports, etc.

4. The collection methods of data mainly include analog acquisition, digital acquisition, pulse acquisition, serial port and network port collection, etc., which are treated differently according to the hardware sensor and controller interface to be collected.Generally, an interface of a collection terminal can connect multiple channels, which can greatly save space and improve the collection efficiency.
