Therefore, the power generation is performed by detecting the chewing motion of the jaw of the livestock, so that the equipment can be monitored for a long time in any environment without considering the power supply environment.
As shown in fig. 2, in the self-powered livestock chew detection device of the embodiment, an elastic member in the housing 1 for connecting the chain rope 2 is a coil spring 6, the end of the chain rope 2 is connected with the coil spring 6, when the chain rope 2 is pulled out, the coil spring 6 is forced to shrink inwards and store energy, and when the stress on the outer part of the chain rope 2 is released, the coil spring 6 relaxes outwards to release the elastic force, so that the chain rope 2 is driven to retract into the housing 1; the coil spring 6 is used, which can be elastically deformed in a small space, and enables the chain 2 to have a large moving distance. In addition, as an alternative embodiment, the elastic member may be other conventional elastic structures, such as a compression spring, etc.
As shown in fig. 2, in the self-powered livestock chew detection device of the present embodiment, two ends of the chain 2 are elastically connected in the housing 1 through the same coil spring 6, so as to further increase the compression amount of the chain 2 on the coil spring 6 and improve the elastic potential energy generated when the coil spring 6 is deformed. In addition, as an alternative embodiment, the coil springs 6 may be provided concentrically, two, each coil spring 6 being provided in connection with one end of the chain 2.

Principle of operation
When the self-powered livestock chew detection device is arranged on the head of the livestock, the chain rope is sleeved on the outline of the periphery of the mouth of the livestock.
When the chain rope is driven by the action of the mouth of the livestock, the chain rope stretches and contracts in the shell, and the blocking piece on the chain rope sequentially passes through the piezoelectric piece, so that the piezoelectric piece bends and vibrates. The electric energy generated by bending the piezoelectric sheet is transmitted to the electric energy storage device, and the electric energy is supplied to the processor by the electric energy storage device. The pulse signals generated by the periodic vibration of the bending of the piezoelectric plate are transmitted to the processor, the processor receives the square wave generated by the vibration of the piezoelectric plate, and the chewing of the livestock during feeding and ruminant is judged through the analysis of the square wave.
Specifically, when the chain rope is pulled outwards, the electric energy voltage generated by bending the piezoelectric sheet is a positive square wave; when the chain rope is contracted inwards to the shell, the electric energy voltage generated by bending the piezoelectric sheet is a negative square wave.
Cumulative square wave change number = square wave number-negative square wave number, the minimum of the cumulative square wave change number (the minimum in the small-before-large process) represents the closing degree in the livestock jaw movement process.
The closing degree is different due to the particle size of forage grass in the livestock oral cavity, and the feeding and the ruminant are particularly obvious, so that the feeding and the ruminant can be judged by accumulating the variation number of square waves.
The judging method comprises the following steps:
the minimum value of the cumulative square wave change number for 2 weeks is automatically collected to form a ruminant jaw closure degree database, the database is divided into three types according to the value, the largest type is judged to be eating, the smallest type is judged to be drinking and the other types are judged to be ruminant, and the eating data is subjected to averaging treatment to obtain an eating threshold value of eating. Similarly, a ruminant threshold is obtained, the feeding and ruminant judgment threshold of the ruminant is formed, the minimum value of the accumulated square wave change number can be judged in real time, when the feeding threshold is larger than the minimum value, the feeding is judged, and when the feeding threshold is smaller than the ruminant threshold, the ruminant is judged.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
