The invention discloses a method for transmitting status data of a controlled self-service device to a serial port of a control host, and belongs to the technical field of self-service products. The control host and the controlled self-service device are characterized in that control host receives and controls data of the controlled self-service device through the own serial port; a circuit for acquiring the status data of the controlled self-service device is connected between the serial port of the control host and the controlled self-service device, and comprises a data sending time-controlling module, a serial port data simulating module, a data receiving module; and the controlled self-service device, the data sending time controlling module, the serial port data simulating module, the data receiving module and the serial port of the control host are connected one by one. Compared with the prior art, the method can acquire the status of the controlled self-service device through a plurality of discrete components and send the data to the serial port of the control host, has the characteristics of rational design, low cost and the like.
Description
technical field [0001] The invention relates to a technology in the field of self-service products, in particular to a method for sending state data of controlled self-service equipment to a serial port of a control host. Background technique [0002] Self-service equipment is a kind of equipment that is completely carried out by customers themselves through computer display terminals (input and output equipment of computer systems). [0003] Most of the self-service devices now use serial ports to communicate, obtain data, and obtain device status. The serial port is a very common device communication protocol on computers and instrumentation equipment, and the serial port communication protocol can be used to obtain data from remote acquisition devices. Serial communication is asynchronous, and the port can send data on one wire while receiving data on the other; it's simple and enables long-distance communication. [0004] Sometimes in order to obtain a usage status of ...
