Background technology
Possum is a kind of equipment that is carried out the miscellaneous service contact fully by client oneself through computing machine display terminal (Input/Output Device of computer system).
Existing most Possums use serial ports to communicate, and obtain data, obtain equipment state.Serial ports is a kind of very general devices communicating agreement on computing machine, the instrument and meter equipment, and serial communication protocol can be used to obtain the data of remote collection equipment simultaneously.Serial communication is asynchronous, and port can receive data simultaneously in transmission data on the single line on other single line; It is very simple and can realize telecommunication.
Sometimes in order to obtain a user mode of controlled self-service device, needs use the single-chip microcomputer judgement and communicate with main frame.This kind way, cost is high, complex structure.
Summary of the invention
Technical assignment of the present invention provide a kind of simple in structure, production cost is low, can obtain the state of controlled self-service device and send data to a kind of method of sending status data of controlled self-service device to the main control system serial ports of the serial ports of main control system through several discrete components.
Technical assignment of the present invention is realized by following mode; Comprise main control system, controlled self-service device; Main control system is controlled with status data controlled self-service device and is received; Main control system carries out Data Receiving, control to controlled self-service device through the serial ports of self, is connected with the status data of controlled self-service device acquisition cuicuit between the serial ports of main control system and the controlled self-service device; The status data of controlled self-service device acquisition cuicuit comprises that control data sends time module, simulative serial port data module, data reception module; Controlled self-service device connects control data and sends time module; Control data sends time module and connects simulation serial data module; The simulative serial port data module connects data reception module, and data reception module connects the serial ports of main control system.
Described status data of controlled self-service device acquisition cuicuit can supply with or use the power supply of external unit to supply with through the serial ports power taking power supply of main control system.
Described status data of controlled self-service device acquisition cuicuit can be supplied with through the serial ports power taking power supply of main control system; Through serial ports self 7 pin, 8 pin and the 6 pin power takings of 4 pin of main control system, produce status data of controlled self-service device acquisition cuicuit required voltage through capacitor C 1 filtering.
Described control data sends time module and controls transmitting time with infrared tube.
Described infrared tube D1, D2 and triode T1, four of T2 are connected in parallel on capacitor C 1 two ends of serial ports power taking power supply supplying module.
During use, serial ports is opened and is in the preparation accepting state, and controlled self-service device determines when to serial ports and sends data.When controlled self-service device will begin that through the control transmitting time serial ports is carried out data and send when serial ports send data.The sequential of signal imitation serial ports RS232 is carried out that serial ports is carried out data and is sent; After serial ports receives data, controlled self-service device is controlled respectively, so that make controlled self-service device carry out next step operation through the divider of main control system; Send to serial ports through data again, form close loop maneuver.
Through power valve D1 and receiving tube D2 during to pipe, T1, T2 all ends, and no datat is seen off.T1 conducting when article pass pipe, the T2 conducting is sent data to serial ports, and serial ports is done handled after receiving data.
A kind of method to main control system serial ports transmission status data of controlled self-service device of the present invention is compared with prior art; Can obtain the state of controlled self-service device through several discrete components; And send data to the serial ports of main control system, report the controlled self-service device user mode; Reasonable in design, simple in structure, cost is low, thereby, have good value for applications.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Accompanying drawing 1 is a kind of structured flowchart that sends the method for status data of controlled self-service device to the main control system serial ports;
Accompanying drawing 2 is status data of controlled self-service device acquisition cuicuit figure.
Among Fig. 2, being serial ports power taking power supply supplying module in the frame of broken lines A, for control data sends time module, is the simulative serial port data module in the frame of broken lines C in the frame of broken lines B, is data reception module in the frame of broken lines D.
