The collection of simulant signal end of equipment is connected with the analog quantity input interface, the switching signal collection terminal is connected with switch value input interface, central processing unit receives the analog quantity and the switching value of above-mentioned interface, and handles, and by the information transmission port data is sent to host computer at last.Like this, need all be connected on signal (switching value or the analog quantity) input interface of signal picker correspondence by the various device of sensor acquisition signal, realize linking of various device and host computer with the information transmission interface of signal picker and the single so point-to-point transmission manner of host computer then by sensor.The all switching values and the collection of analog quantity all can focus on by signal picker described in the utility model, and then send to host computer, like this, have just simplified the installation and the construction of circuit, administer and maintain all to become convenient and easy.
The utility model can further be specially:
Also include the relay output interface, it is connected with the transmit port of central processing unit.
After central processing unit is received the steering order of host computer, this control signal is transferred to the control of miniature relay equipment realization to commercial unit by the relay output interface.Central processing unit self also can send steering order and by the relay output interface commercial unit be controlled.
Like this, signal picker described in the utility model also has relay control output function, satisfies request signal transmission back and forth such as the collection of signal and control.
Also include relay self check interface, it is connected with the transmit port of central processing unit.
Relay self check interface receives the switching signal of pilot relay, and is transferred to central processing unit and transmits.After central processing unit sends control signal, can be by the monitoring of relay self check interface realization to relay control signal.
Also include toggle switch, it is connected with a transmission interface of central processing unit.
Toggle switch is used for to compiling the address in the central processing unit information transmitted, and information just can select corresponding interface to transmit when transmission like this.
Also include display device, display device is connected with the output terminal of central processing unit.
Display device makes things convenient for the staff that signal picker is carried out various operations as the man-machine dialogue interface of signal picker.
Information transmission interface is a kind of RS485 interface, or a kind of RS232 interface, or the combined interface of said two devices.
The utility model can also further be specially:
It is the process chip of SST89E516RD and auxiliary circuit on every side thereof that central processing unit includes a model, switch value input interface has one at least, be 8 way switch amount interfaces, the interface chip model is 74LS244, the analog quantity input interface has one at least, be 11 tunnel analog quantity interfaces, interface chip is a kind of AD chip, and model is TLC2543.
In sum, the utility model provides a kind of signal picker, it combines the acquisition function of various switching values and analog quantity, possesses relay control output function simultaneously, the all switching values and the collection of analog quantity all can focus on by signal picker, and then send to host computer, like this, just simplified the installation and the construction of circuit, administered and maintained and all become convenient and much easier.
Description of drawings
Figure 1 shows that the electrical block diagram of signal picker described in the utility model.
Below in conjunction with embodiment the utility model is described further.
Specific embodiment
Most preferred embodiment:
With reference to accompanying drawing 1, signal picker includes two 8 way switch amount input interfaces, and adopting model is the interface chip of 74LS244, two 11 tunnel analog quantity input interfaces, and adopting model is the AD chip of TLC2543; Central processing unit, adopting model is the process chip of SST89E516RD; Relay self check interface, adopting model is the interface chip of 74LS244; The relay output interface; Display device adopts the LED display device; Toggle switch is a kind of device for transmission data volume address; Information transmission interface comprises RS485 interface and RS232 interface.
