Embodiment Construction
[0022] A further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention:
[0023] figure 1 It is a structural diagram of an electronic weighing instrument. The electronic weighing instrument includes a controller module 1, on which a weighing module 2, a key module 3, a display module 4, a communication module 5, a private MIB library 6 (management information base) and The wireless network module 7 is used for wireless connection with the wireless access point on the network. The invention is to embed the customized and perfect private MIB library into the SNMP agent module, and make it take effect through the corresponding interface function.
[0024] Such as figure 2 , through the network management system, the private MIB library customized by the electronic weighing instrument can be easily accessed to realize remote operation.
[0025] Such as image 3 , the customization method of the present i...

The invention discloses a method of customizing an electronic weighing apparatus with a private MIB (Management Information Base), which comprises the following steps that: a wireless network module wirelessly connected with a wireless access point in a network is configured in the electronic weighing apparatus; an SNMP (Simple Network Management Protocol) agent module is loaded in the wireless network module; parameters of the SNMP agent module are configured; the private MIB for storing private MIB information is configured in the electronic weighing apparatus; the private MIB is designed according to data parameters related to the electronic weighing apparatus; a corresponding C code frame is generated from a private MIB document by the SNMP agent module; a C code is perfected according to requirements; the corresponding private MIB information is compiled into a C document; an SO (Shared Object) dynamic library document is generated from the perfected C document by a gcc (GNU Compiler Collection) compiler in a controller module; the SO dynamic library document is transplanted to the SNMP agent module; finally the SNMP agent module is restarted; interface functions of the private MIB information in the corresponding private MIB are compiled; and the private MIB information can immediately take effect in the electronic weighing apparatus when being changed by other clients.
Description
[technical field] [0001] The invention relates to a method for customizing an electronic weighing instrument with a private MIB library. Considering all the basic information needed by the electronic weighing instrument, the private MIB library is designed, embedded in the electronic weighing instrument, and corresponding function operations are written, so that the MIB can be obtained through the network client. Can directly manage electronic scales. [Background technique] [0002] As early as 2002, the European Commission issued EC No178 / 2002 regulations, requiring that from 2005, all food sold in EU countries must have a traceability function, otherwise it will not be allowed to be sold on the market, and food without traceability will be prohibited from import. In recent years, in order to promote the traceability management of food safety, my country has issued a series of No. 1 documents to implement the construction plan of agricultural product quality and safety insp...
