Embodiment 1
[0043] Modular intelligent fusion terminal based on analog bus communication such as figure 1 As shown, it mainly includes the main control board 11 for module identification and module communication, and the general interfaces 1-6 for completing various functions. The main control board is mainly composed of an ARM chip and a power circuit, wherein the power circuit provides power for the general interface, and the ARM chip provides the identification port line and the communication port line for the general interface.
[0044] In order to better illustrate that the hardware terminal of the present invention dynamically matches multiple types of bus and multiple user modules, firstly, a modular intelligent fusion terminal hardware general interface IO mapping table is established, as shown in Table 1. And realize the hardware circuit design of the terminal according to the table, such as Figure II shown.
[0045] Table 1 IO mapping table of general interface of modular intel...
