An improvement over the prior art.
The LUA script language replaces part of C language programs, so that the functions of the collector equipment are realized by light weight, the compiling amount of C program codes is reduced, and the storage space of the collector equipment occupied by the programs is reduced. Compared with the function of realizing the embedded equipment by a pure C language program, the LUA script language is more powerful and convenient.
2. The existing embedded device generally only packages and uploads data, and data analysis is generally not realized on a device terminal, but is handed to an IOT platform end (or other back ends) to realize the function, so that the data analysis is troublesome and needs to be realized by designing other compiling language programs.
3. The present example replaces the OTA of existing embedded devices with LUA script hot-update. In the prior OTA technology, a program C is packaged and sent to a collector in a bin file form (generally M is a unit) for integral upgrade, the whole upgrade process is influenced by a network or the installation position of equipment, the bin file occupies a large storage space and is slow in transmission process, and once a problem occurs in the process, the bin file is troublesome to retransmit. By adopting the LUA hot updating mode and taking the C program as a main body, the LUA script only plays an auxiliary role, different medical equipment can be adapted only by issuing the LUA script file during hot updating, the burnt C program does not need to be changed, the function of the collector equipment can be expanded only by a plurality of KB LUA scripts, and the OTA is more convenient and faster.
Has the advantages of simple process and low cost.
1. And innovative technology application. The hot update technology is commonly used for updating application programs of mobile terminals such as mobile phones, the embedded device adopts C language for compiling and programming, a single C language program cannot support hot update, the example realizes the hot update of the embedded device by using the LUA script, and the method is an innovation of an update mode of the embedded device.
2. High efficiency. Compared with the existing updating mode of the embedded equipment, the LUA script is updated in a hot mode, only the LUA script language part needs to be updated, the C program which is burnt in advance does not need to be changed, the time of the whole updating process is shortened, and the erasing and copying operation of the hardware memory chip of the collector is less and more effective due to the LUA script hot updating.
3. And (4) stability. The collector normally runs without depending on the LUA script, and the LUA script is only the extension of the collector function. The LUA hot updating process does not affect other functions of the collector, when the LUA script is in a problem during hot updating, the collector can be normally connected with the IOT platform, and other basic functions can be stably performed.
4. And (4) starting from original source. The LUA scripting language source code is open-source and official allows for various business programs, with subsequent version iterations and functional extensions.
