Detailed description of the invention
Fig. 1 is the electrical structure diagram of the utility model voltage sensor circuit.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, it is practical new this is described in detail
Before the technical solution of each embodiment of type, related noun and term are explained, in the present specification, title is identical
Or the identical component of label represents similar or identical structure, and is only limitted to the purpose of signal.
As shown in Figure 1, the voltage sensor circuit includes the first divider resistance R1, the second divider resistance R2, filtered electrical
Hold C, first diode D1 and the second diode D2.
One end of the first divider resistance R1 and one end of the second divider resistance R2 are being separately connected the battery of unmanned boat just
Pole and cathode, so that entire voltage sensor circuit is connected on battery output main line, wherein the second divider resistance R2 is separated
Voltage be detection voltage, be connected with master control voltage detecting mouth, be transferred in master control.
In order to meet the requirement of master control collection voltages, needs will test voltage value and limit this implementation in a certain range
Detection voltage range is 0-5V in example, is defined using first diode D1 and the second diode D2 to detection voltage, specifically
Ground:
The first diode D1 anode be connected with the cathode of the second diode D2, the cathode of first diode D1 with outside
It connects threshold voltage to be connected, the plus earth of the second diode D2, wherein external threshold voltage is+5V.First diode in circuit
The effect of D1 is to make to detect voltage no more than 5V, because detection voltage is greater than 5V, first diode conducting, transmission voltage is equal to two
Pole pipe cathode voltage is equal to 5V.The second diode D2 effect is to make to detect voltage not less than 0V, because detection voltage is small in circuit
In 0V, the second diode current flow, detection voltage is equal to diode anode voltage and is equal to 0V.
It is also added into filter capacitor C in voltage sensor circuit, the cathode of the filter capacitor C is grounded, filter capacitor C's
Positive tie point and first diode D1 and the second diode D2 with the first divider resistance R1 and the second divider resistance R2 respectively
Tie point be connected, and the output end as the voltage sensor circuit.The pressure voltage of filter capacitor C is detect voltage two
Times, it prevents capacitor breakdown, ensure that the stability and accuracy of circuit.
The detection voltage of voltage sensor is analog quantity, and master control needs for analog quantity to be converted into digital quantity and carries out operation.It is main
The controller of control is STM32F427VGT6, there is the ADC(analog-digital converter of 12 successive approximations inside controller), inspection
Survey voltage and by the ADC in controller say that analog quantity is converted into digital quantity and is placed in ADC_DR register, by formula temp=
Adcx* (3.3/4096) calculates detection voltage temp, and adcx is the numerical value in register, and temp is waited until multiplied by Proportional coefficient K
Virtual voltage (V).A variable (V1) is defined in primary control program, by V1 compared with V, if V is less than V1, unmanned boat returns automatically
Boat, unmanned boat will be realized to make a return voyage automatically, and setting one is maked a return voyage a little first in lake, and making a return voyage a little has the information such as latitude, longitude, nobody
Ship is driven to and is maked a return voyage a little by integrated navigation system (GPS, compass, magnetometer, the navigation system collectively constituted) self-navigation.It is main
Program in control can be contacted variable (V1) in the form of a parameter with host computer foundation, and commissioning staff or user can be upper
Position machine changes this parameter to which the voltage value that unmanned boat low-voltage is maked a return voyage be arranged.
