One kind walks ground pig and forms method
Technical field
The present invention relates to pig raising field, in particular to it is a kind of walk ground pig form method.
Background technology
Pork is the food that people like eating.In order to meet a large amount of demand of the people to pork, most pig is all
Urged in stable breeding, forage feed long, meat not consolidation and fat meat is very much, mouthfeel is not very good enough, and nutrition is received extensively
Query, for full of nutrition especially for this needs of child and free of contamination group, this pork can not meet child couple
The demand of high-quality meat proteins.
Existing mode be only it is artificial swine rearing environment intervened, improve pig as possible and give birth to and bring up amenity
Degree, provide big as possible space to pig come enable pig relatively it is free it is movable so as to improve in pork the ratio of lean meat and then
Improve meat quality.It is typically to be unwilling to carry out however, there is no the conduct of itself is limited by, such as sluggish in view of pig
Activity.

Embodiment two.
One kind walks ground pig and forms method, which is characterized in that this method includes:
When pig, which lifts foot, will ride on the support surface again, due to the gravity of pig itself, the pressure being fixed under pig's feet
Electric material can generate the electric power of pulsatile once, and when pig persistently implements trample action, the piezoelectric material can generate multiple pulses
Electric power;
The piezoelectric material layer includes the piezoelectric material that can directly convert pressure into electric power, and then directly using pig certainly
The weight of body produces electricl energy, and then directly charge so that method is easy to implement and easy to use;
The electric power of the pulse is stored in ultracapacitor, so that the voltage step of the ultracapacitor
Constantly rise, and detect the voltage of the ultracapacitor in real time;When the voltage of the ultracapacitor reaches predetermined threshold value,
Record the number that the ultracapacitor voltage rises, the weight of pig estimated according to the number, and control with it is described super

The electric power of constant voltage, current class, the predetermined voltage, current class electric power be transferred to accumulator group and then to the electric power storage
Pond group charging;The capacity of the accumulator group should be set identical with the capacity of the ultracapacitor so that when described super
When grade condenser voltage reaches predetermined threshold value for the battery charging, the operation being closed by the primary first switch is
It can be fully charged by the accumulator group;
It is required that the electric power of pulse is initially stored in super capacitor, because if the electric power using pulse is directly right
Battery, which carries out charging, will seriously affect the service life of battery, therefore, realize the storage of electric power using super capacitor first, only
Have when the voltage of super capacitor reaches predetermined threshold value just to battery charging and then the performance of guarantee accumulator group;In addition,
Due to varying in weight for pig, the pressure trampled when on foot will be different, and then can lead to the impulse magnitude of pulse power not
Together, and the pulse conference of pulse power so that super capacitor reaches predetermined threshold value by the charging of less number, therefore, remember
The number that the ultracapacitor voltage of record rises can characterize the weight of pig;
The ultracapacitor group for the super capacitor monomer for including multiple connection in series-parallel connections can also be used and/or including more
The accumulator group of the single battery of a connection in series-parallel connection;Pass through flexible electric connection between each electric power component;
The voltage of the accumulator group is detected in real time, when the voltage of the accumulator group reaches upper voltage limit, controls institute
First switch disconnection is stated, and then is stopped to the battery charging, and controls accumulator group to the be arranged near pig's feet
One ultrasonic transmitter-receiver is powered so that first ultrasonic transmitter-receiver sends a ultrasonic wave, while accumulator group is controlled to pass through
DC/AC converters provide electric power to wireless power sending device, and the electric power of receiving is transformed by the wireless power sending device
The electromagnetic field of variation is arranged on the wireless power accepting device at pig neck and is located in the electromagnetic field and then will generate electric power, will
The electric power is received by being transferred to the second ultrasonic transmitter-receiver being arranged at pig neck, second ultrasonic wave after AC/DC converters
It sends out device and then the ultrasonic wave can be received and the ultrasonic wave is further returned into first ultrasonic transmitter-receiver, according to institute
The first ultrasonic transmitter-receiver is stated to send ultrasonic wave and receive the time interval of ultrasonic wave to calculate the height of pig;
The density of pig is judged according to the height and the weight, when the density is more than pre-set density, control and electric power storage
The second switch of pond group connection is closed, so as to be formed from the accumulator group, second switch, the confession for being close to the electrode that pig's feet is set
Power path, so that pig's feet is stimulated by weak current so that pig experiences the feeling itched, so as to which pig be stimulated to walk about;
Since the transmission speed of sound wave is known, in the case where knowing its propagation time both it is known that sound wave
The distance of transmission, i.e., from pig's feet to twice of the distance of pig neck, therefore the height of pig is close to the half of sonic transmissions distance;In order to
Computational accuracy is improved, can also further consider that the distance between to pig's head top, a coefficient may be used to be multiplied by pig neck
The half of sonic transmissions distance obtains the height of pig;The density of pig can be BMI indexes, height that can also be according to pig, body
It is fitted new function curve again and then obtains more accurately model;To the control of second switch can be set as pig into
Controller is closed certain time after having eaten, and the time size of the density to being obtained is related, the time if the density is larger
Should be also larger so time of pig movement for controlling figure more fat it is longer;
The electrode includes the positive electrode, the negative electrode that are in direct contact pig's feet bottom plate respectively, exists between positive electrode, negative electrode
Physical distance, the size of physical distance depend on the size of the resistance of pig body and the electric current of use.
