The signal transmission module 103 may be configured to acquire a voltage signal of the piezoelectric transducer probe 202 when it is monitored that the piezoelectric transducer probe 202 of the target stretching length is excited, and transmit the voltage signal to the control terminal 301.

The bite evaluation module 104 can be used for the control terminal 301 to perform signal processing on the voltage signal to obtain bite force data, and evaluating the bite ability of the rodent according to the bite force data.

An embodiment of the present invention further provides a computer readable storage medium, on which a computer program is stored, and the computer program, when executed by the processor 30, implements the steps of the bite force measuring method in any of the above embodiments.

The bite force measuring device 100/computer device integrated module/unit may be stored in a computer readable storage medium if it is implemented in the form of a software functional unit and sold or used as a stand-alone product. Based on such understanding, all or part of the flow in the method according to the above embodiments may be implemented by a computer program, which may be stored in a computer readable storage medium and used by the processor 30 to implement the steps of the above method embodiments. Wherein the computer program comprises computer program code, which may be in the form of source code, object code, an executable file or some intermediate form, etc. The computer-readable storage medium may include: any entity or device capable of carrying the computer program code, recording medium, U disk, removable hard disk, magnetic disk, optical disk, computer Memory, Read-Only Memory (ROM), or the like.

The Processor 30 may be a Central Processing Unit (CPU), other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, discrete Gate or transistor logic device, discrete hardware component, or the like. The general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, said processor 30 being the control center of said occlusion force measuring device 100/computer device 1, the various parts of the entire occlusion force measuring device 100/computer device 1 being connected by means of various interfaces and lines.

The memory 10 is used for storing the computer program and/or module, and the processor 30 implements various functions of the occlusion force measuring device 100/computer device 1 by running or executing the computer program and/or module stored in the memory 10 and invoking data stored in the memory 10. The memory 10 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data created according to the use of the computer apparatus 1, and the like.

In the several embodiments provided in the present invention, it should be understood that the disclosed computer apparatus and method may be implemented in other ways. For example, the system embodiments described above are merely illustrative, and for example, the division of the modules is only one logical functional division, and other divisions may be realized in practice.

It will be evident to those skilled in the art that the embodiments of the present invention are not limited to the details of the foregoing illustrative embodiments, and that the embodiments of the present invention are capable of being embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the embodiments being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned. Several of the units, modules or means recited in the system, apparatus or computer device claims may also be implemented by one and the same unit, module or means in software or hardware.

Although the embodiments of the present invention have been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the embodiments of the present invention.
