Description
Technical field
The utility model relates to a kind of input expansion module.
Background technology
Existing opertaing device is due to factors such as cost and shell shapes, the input port that gathers external signal arranges limited, in in the face of complicated controling environment, when needs gather a plurality of analog input data and a plurality of switching value signal, separation equipment overlaps conventionally like this, such as using relay array to overlap, so once can only receive data or signal, and wiring is complicated, transmission stability is low, transfer efficiency is not high, and cost also promotes a lot.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thereby a kind of input expansion module is provided, to solve the problem that wiring is complicated, transmission stability is low, transfer efficiency is low and cost is high of using separation equipment to cause in prior art.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of input expansion module, comprise switching value module, data acquisition module, CPU module and CANBUS communication module, described switching value module comprises a plurality of switching quantity detection circuits, described data acquisition module comprises a plurality of data acquisition circuits, described in each switching quantity detection circuit and described in each output terminal of data acquisition circuit be all connected to process to the received signal with the input end of described CPU module, the output terminal of described CPU module is connected with described CANBUS communication module to the signal after processing is sent to opertaing device by this CANBUS communication module.
Based on above-mentioned, described CPU module is microcontroller circuit.
Based on above-mentioned, described switching value module, described data acquisition module, described CPU module and described CANBUS communication module are all located on same substrate.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model input expansion module, switching value module comprises a plurality of switching quantity detection circuits, data acquisition module comprises a plurality of data acquisition circuits, each signal that need to gather like this, can to CPU module, transmit simultaneously, to process to the received signal, the output terminal of CPU module is connected with described CANBUS communication module to the signal after processing is sent to opertaing device by this CANBUS communication module, wiring is simple, there is extendability flexibly, because CANBUS bus data transfer rate is high, transmission is stable, so CANBUS communication module real-time signal transmission to meet different device requirements.
Accompanying drawing explanation
Fig. 1 is the system chart of input expansion module in the utility model embodiment.
