l ELECTRONIC BALANCE DATA RECORDING SYSTEM AND DATA TRANSMISSION CONTROL METHOD TECHNICAL FIELD [Ol] The present invention relates to an electronic balance data recording system and a data transmission control method, which. belong' to the technical field. of paperless recording of instruments and apparatuses. BACKGROUND ART

[02] An electronic balance is the most commonly used basic support instrument in the field of analytical testing. For example, in quantitative analysis of soil and plant components, it is necessary to use the electronic balance to weigh the mass of a sample. For another example, in soil salinity analysis, it is necessary to use the electronic balance to repeatedly weigh the same beaker at different time until the beaker is constant. The workload of data recording and input is extremely large, and frequent manual recording is the main reason for data errors.

[03] Usually, when the electronic balance is used for weighing samples in a laboratory, it is necessary to manually record data, and then, the data are input into a computer, and then processed. When the amount of data is large, an experimenter is likely to make mistakes in the process of data transfer, and data entry is also a lot of work. Laboratory electronic balances are equipped with RS232 and. other serial port interfaces. The purpose of reserving' RS232 is to connect the balance to a stylus printer or the computer for data output. After the stylus printer is configured, mass data of weighing of the samples are printed item. by item. through the printer. However, the printed data still need to be manually input to the computer for subsequent processing, and the workload. has not been significantly reduced. .After the computer is configured, the data can be effectively transferred, but each balance needs to be configured with one computer, which occupies the space of the laboratory, and which is a main reason why each laboratory does not do so. Moreover, only display data of the balance can be recorded, container names and sample names corresponding to the weighing data fail to be recorded, and fault tolerance, error correction and log control for all the data also fail to be completed Therefore, there is an urgent need. to develop a convenient and fast paperless recording system. SUMMARY
