Abstract

The invention relates to a device for expanding a semaphore acquisition port. The device comprises a first communication interface, a logic device, one or more analog quantity acquisition units and / or one or more switching value input / output units, wherein the first communication interface communicates with an upper computer; and the logic device is in communication coupling with the first communication interface. Each analog quantity acquisition unit is provided with one or more analog quantity input ports, and is used for acquiring one or more analog quantity signals to the logic device and configuring the analog quantity input ports through a control signal from the logic device. Each switching value input / output unit is provided with one or more switching value input / output ports. According to the expanding device provided by the invention, the semaphore acquisition port of the existing hardware equipment can be expanded through simple physical line connection.

Description

technical field [0001] The invention relates to an expansion device. More specifically, the present invention relates to a device for expanding a semaphore collection port. Background technique [0002] In the fields of industry, agriculture, animal husbandry, etc., more and more devices that can collect a large number of analog signals and switching signals are required. When the existing equipment in the project cannot meet the requirements of use with the expansion of the project scale and function expansion, redesigning or modifying the equipment hardware will cause a waste of money and time. An expansion device and an expansion method for expanding a port for collecting signals. Such an expansion device needs to have the characteristics of low pin count, flexibility, and ease of development, and the ability to further adjust the number of ports according to actual needs. [0003] In the prior art, embedded devices are usually used for on-site data collection and cont...
