if the type of the pelvic floor probe is a repeatable probe type, the encryption mark is valid, and the repetition mark is not repeated, when the remaining times of the pelvic floor probe is 0, determining that the pelvic floor probe is in a failure state, clearing ciphertext authentication information in the pelvic floor probe, and recording an identification code of the pelvic floor probe in historical record information; when the remaining times of the pelvic floor probe are not 0, determining that the pelvic floor probe is in an effective state, recording the identification code and the remaining times of the pelvic floor probe in historical record information, and recording the identification code and the remaining times of the pelvic floor probe in variables corresponding to the cache;
if the repeated mark of the pelvic floor probe is not repeated or repeated and the encryption mark is invalid, determining that the pelvic floor probe is in a failure state;

Above-mentioned pelvic floor probe management module installs inside the host computer, mainly by peripheral basic circuit such as microcontroller and power, the pilot lamp, serial ports drive and opto-coupler isolation and constitute, the core is a microcontroller that has multiple serial ports and storage system, above-mentioned second microcontroller promptly, pelvic floor probe management module links together through electrode line and pelvic floor probe on the one hand, for pelvic floor probe power supply and communication, on the other hand passes through the serial ports data line and links to each other with pelvic floor probe control module 23. The built-in storage system of the pelvic floor probe management module is used for storing the used unique identification code of the effective pelvic floor probe and the corresponding remaining times, and the data are not lost when power is lost.
Based on the status of the pelvic floor probe determined by the second microcontroller 222 of the pelvic floor probe management module 22, the pelvic floor probe control module 23 is further configured to: (1) when the pelvic floor probe is in an effective state, setting a function control for operating the pelvic floor probe to be in an available state, and when the operation control is triggered, sending a command of subtracting 1 from the remaining times to a pelvic floor probe management module, so that when the pelvic floor probe management module receives the command, the pelvic floor probe management module subtracts 1 from both the remaining times of the pelvic floor probe and the remaining times of the pelvic floor probe in the historical record information, and adds the effectiveness of the pelvic floor probe and the current remaining times to a pelvic floor report; (2) and when the pelvic floor probe is in an invalid state or an abnormal state, setting the function control for operating the pelvic floor probe to be in an unavailable state so as to forbid the use of the pelvic floor probe.
When the integrated pelvic floor machine is applied, peripheral components such as cables of a pelvic floor probe and the like can be connected firstly, and then the host machine is powered on and started. After the device is started, the pelvic floor probe control module 23 enters a main interface to provide a functional control of the pelvic floor probe for a user to select, when the function of the pelvic floor probe is started to be triggered, the pelvic floor probe control module 23 sends a command to the pelvic floor probe management module 22 to inquire the current state of the pelvic floor probe, and the pelvic floor probe management module 22 reads plaintext authentication information and ciphertext authentication information stored in the pelvic floor probe 1 and judges whether the connected pelvic floor probe 1 is valid according to the acquired information. If the pelvic floor probe is not correctly connected or the pelvic floor probe is connected in an invalid state, the functional control of the pelvic floor probe is in an unavailable state, the corresponding function of the control cannot be used, and only if the pelvic floor probe is verified to be effective, the pelvic floor probe control module 23 can be communicated with the pelvic floor probe, so that subsequent functions of health state assessment, rehabilitation training and the like are realized.
The pelvic floor probe control module mainly comprises an upper computer and a functional hardware module. The upper computer performs ciphertext communication with the pelvic floor probe management module through the serial port (both sides encrypt communication contents according to a well-agreed encryption mode and then send the encrypted communication contents, and decrypt the received contents according to a well-agreed decryption mode) to obtain the current state of the pelvic floor probe, if the pelvic floor probe management module returns that the pelvic floor probe is in an effective state, the pelvic floor probe control module is allowed to perform specific operations such as evaluation, screening and rehabilitation through the serial port control function hardware module, and if the pelvic floor probe management module returns that the pelvic floor probe is in an invalid or abnormal state, the pelvic floor probe control module is not allowed to enter. After entering, the pelvic floor probe control module can also inquire the state of the pelvic floor probe at regular time, and stop working when finding that the probe returns to an invalid or abnormal state. When the operation is about to be finished, the pelvic floor probe control module sends a command to the pelvic floor probe management module through the serial port, so that the remaining times of probe storage corresponding to the currently used pelvic floor probe and the remaining times of the pelvic floor probe management module are reduced by one at the same time. For a one-person multi-time type pelvic floor probe, when the secondary remaining time is reduced to 0, the pelvic floor probe fails; for the disposable pelvic floor probe, the pelvic floor probe fails when the remaining number of times is 0, or fails when the ciphertext authentication information is reset and cleared even if the remaining number of times is not 0 as long as the unique identification code is inconsistent with the variable of the unique identification code of the currently used pelvic floor probe of the pelvic floor probe management module.
