Beneficial effect：A kind of device for preventing motor operation from disturbing data acquisition Serial Port Transmission of the present utility model, structure
Simply, it can be avoided from physical layer when host computer is not separated also with control panel, control panel has operated startup slave computer,
Neutral signal is produced after slave computer running and turns the situation that serial ports influences host computer to run by connecting the USB of host computer.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is done below in conjunction with the accompanying drawings and further explained.
As shown in figure 1, a kind of device for preventing motor operation from disturbing data acquisition Serial Port Transmission, including relay
HK4100, USB turn serial port chip CH340G, pump motor M and microcontroller, and microcontroller can be the processing such as single-chip microcomputer
Device.Relay HK4100 input circuit one end is connected by current-limiting resistance R1 connection external power sources, the other end of input circuit
Pump motor M positive source.Microcontroller connects external power source, the opening and closing for controlling external power source.Relay HK4100
Output loop include movable contact and the first stationary contact and the second stationary contact, movable contact is grounded by earth resistance R2, first
Stationary contact is connected with the USB earth terminal GND for turning serial port chip CH340G, the power cathode of its second stationary contact and pump motor M
Connection, and relay HK4100 movable contact and the first stationary contact are normally closed.
In addition, circuit part also includes a diode IN4007, the positive pole of diode connects the positive pole of motor, diode
Negative pole connection external power source.The diode refers to relay fly-wheel diode, and it is used for protecting other elements not in circuit
Sensed voltage breakdown is burnt out, and is connected to the element two ends that relay produces induced electromotive force in parallel, and with its shape
Into loop, the high electromotive force that it is produced is consumed in loop with continuous current system, thus play element in protection circuit not by
The effect of damage.
In this circuit, microcontroller is as the part of the control panel of motor, and microcontroller turns serial ports core by USB
Piece can be with host computer, and such as mobile phone, apparatus such as computer carry out communication connection, so that host computer is configured to motor control.This
During the circuit work of utility model, according to the setting of host computer, the opening and closing time of microprocessor control external power source, make
Motor is run by the requirement of setting.
When external power source is turned off, relay HK4100 movable contact and the first stationary contact are normally closed, i.e., USB turns serial port chip
CH340G earth terminal GND is grounded by earth resistance R2, and now microcontroller normally can lead to host computer progress data
News, and pump motor M is in run-stopping status.
When microprocessor control external power source exports electric energy, when electric current passes through the input circuit of relay, relay
Movable contact is acted, and it disconnects with the first stationary contact, and is closed with the second stationary contact；External power source is defeated by relay HK4100's
Entry loop to motor positive source, then after the connection for passing through relay HK4100 movable contacts and the second stationary contact be grounded, formed
Circuit loop, motor starts to run well.Now, because the movable contact of relay and the first stationary contact disconnect, USB turns serial ports core
Piece CH340G earth terminal GND is not grounded, and USB turns serial port chip CH340G i.e. cisco unity malfunction, for controller just now
Data communication can not be carried out with host computer；Therefore during motor operation the neutral signal that produces cannot by microcontroller and
USB turns serial port chip and passes host computer, thus the influence for avoiding the operation of slave computer from producing host computer back.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
