Bus system, carry detection sample feeding module, data acquisition module, sample detection module, signal transacting mould in CAN
Block, data disaply moudle, print module；
Each word modules set the address of this module by respective controller, and master controller is sent by CAN and instructed
Or during data, each submodule matches the instruction for performing master controller transmission respectively or the number for receiving master controller transmission by address
According to；
After full-automatic detecting instrument system starts, each submodule sends respective initial information by CAN, main
Controller receives the information that each module is sent and whether interpretation information is effective, if invalid transmission instruction requires designated module again
Initial information is sent, then judges whether the module has been completed to initialize if effective information, is sent out if fruit does not complete initialization
Initialization directive is sent, submodule receives instruction, and whether row address matching judgment of going forward side by side performs the instruction, while judges whether to have connected
It is continuous to perform multiple initialization directive, if continuously performing number more than 3 times, the system failure is sent by CAN and instructed,
Each submodule receives out of service after the instruction, if not less than 3 times, normal operation initialization directive, is finished to master
Controller sends initialization and completes information, and the initialization of system is completed with this；
After submodule initialization block is completed, master controller sends system operating instructions by CAN, and all modules all receive this
Instruction, submodule is by comparing Self address and receiving whether command information unanimously refers to judge whether the instruction performs this
Order.
The detection sample feeding module include by the auto injection disk of stepper motor or DC Motor Drives, sample introduction needle,
Fixed-quantity injector, single-pass or multiple-way valve, mixing mechanism.
The sample detection module includes physics and biochemistry detection circuit.
The signal processing module includes signal filtering, amplification, analog to digital conversion circuit.
The data disaply moudle includes：Liquid crystal display, charactron, touch-screen.
The print module includes thermal printer, impact printer, ink-jet printer.
It is additionally provided with other supplementary modules, including bar code scanner, two-dimensional code scanning device.
Compared with prior art the invention has the advantages that：
The present invention is simple in construction, and cost is cheap, technology maturation, has the possibility of extensive exploitation application.
The sample introduction module of the auxiliary of master controller and instrument periphery of the invention by medical detecting Instrument, detection module, letter
Number modular converter, display, print data memory module are mounted in CAN, relatively independent between modules, can be lifted
Development efficiency, while versatility is stronger, conveniently can add or delete a certain module.
Control algolithm relative maturity, the intelligence degree of medical detecting Instrument can be lifted, there is certain fault self-checking
Survey ability.
Controller is connected by way of CAN with submodule, improves the stability and interference free performance of system.
Brief description of the drawings
Fig. 1 is that present system forms sketch.
Fig. 2 is submodule CAN carry sketch of the present invention.
Fig. 3 is present invention operation control flow chart.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
The embodiment.
Fig. 1 be the present invention system form sketch, the system of the full-automatic medical detecting Instrument based on CAN, including：
Detect sample feeding module, data acquisition module, sample detection module, signal processing module, data disaply moudle, printing etc. its
His supplementary module and a set of CAN bus system.Master controller includes：The control chip such as single-chip microcomputer, ARM, FPGA, DSP；Detection
Sample feeding module bag：By the auto injection disk of stepper motor or DC Motor Drives, sample introduction needle, fixed-quantity injector, single-pass or
Multiple-way valve, mixing mechanism；Sample detection module includes：Various physical detections, biochemistry detection circuit, signal processing module include：
The filtering of signal, amplification, analog to digital conversion circuit；Data are shown and print module includes：Liquid crystal display, charactron, touch-screen,
Thermal printer, impact printer, ink-jet printer etc.；Other supplementary modules include：Bar code scanning, two-dimensional code scanning etc.；
The conventional module of above medical treatment detection and other supplementary modules are mounted in CAN respectively as independent node.Master control
Device and submodule processed realize the control of a whole set of medical detection system by respective CAN controller and CAN transceiver respectively
Operation and data transfer.
Fig. 2 is each submodule CAN carry sketch of the present invention, and submodule includes corresponding executing agency and son is touched
The controller of block, CAN controller, CAN transceiver.
Fig. 3 is that system performs basic flow sheet, master controller and submodule by CAN transmission data and instruction come complete
Help the startup of automatic medical detector, initialization, sample detection, data show that printing, fault detect etc. control.
After full-automatic detecting instrument system starts, each submodule sends out respective initial information by CAN
Go, master controller receives the information that each module is sent and whether interpretation information is effective, if invalid transmission instruction requires to specify mould
Block sends initial information from new, then judges whether the module has been completed to initialize if effective information, if fruit does not complete initially
Change then sends initialization directive, and submodule receives instruction, and whether row address matching judgment of going forward side by side performs the instruction, while judgement is
It is no to have continuously performed multiple initialization directive, if continuously performing number more than 3 times, system event is sent by CAN
Barrier instruction, each submodule receive out of service after the instruction, if not less than 3 times, normal operation initialization directive, have performed
Finish to master controller and send initialization completion information, the initialization of system is completed with this.
After submodule initialization block is completed, master controller sends system operating instructions by CAN, and all modules all connect
Receive the instruction, submodule is by comparing Self address and receiving whether command information unanimously judges whether the instruction performs this
Instruction, the logic control of a whole set of medical detection system is realized with this, and submodule program is general, by respective address so as to performing
The part performed in general program required for this module.
Each submodule run by main controller controls it is relatively independent, when system breaks down, only malfunctioning module need to be entered
Row, which is safeguarded or changed, can solve problem, substantially reduce system maintenance and maintenance cost.The system is reserved with section in CAN
Point, when detecting system needs to carry out upgrading, it need to only upgrade a certain module, or addition corresponding module.Medical detector
For device in addition to detection module, other, which include the modules such as auto injection module, data acquisition module, display printing, has very big lead to
, only need to be according to detected material characteristic changing detection module and part master controller in Medical Instruments R＆D process with property
Control program and execution logic can both research and develop new medical detecting Instrument.
