The invention discloses a detection device of an optical ghost image near an optical axis, and the detection device is used in an optical system. The detection device comprises a laser, wherein a collimating lens, a half-passing and half-reflecting lens and a total reflective lens are arranged in turn in the laser beam output direction of the laser; an aperture with a small hole and a CCD charge coupled device)-array detector provided with an adjustable attenuator are arranged in turn in the reflected light directions of the half-passing and half-reflecting lens and the total reflective lens; the CCD-array detector is placed on a linear guide rail with location scales; the CCD-array detector is driven by a driver to move on the guide rail; the input end of the driver is connected with the output end of a computer; and the output end of the CCD-array detector is connected with the input end of the computer. The detection device provided by the invention can verify the ghost image in the optical system, thus increasing the safety of the high-power laser system. The device is suitable for the detection of the optical ghost image on the axis of the large-diameter lens; the device has the advantages of being simple in structure, convenient to move and easy to realize and overcoming the defect that the broad beam ghost image is difficult to detect.

The invention discloses an optical network unit (ONU) certification authorization management method based on License resource control and relates to the field of ONU management methods. According to the method, ONUs apply License resources, if the License resources are applied, a master control disk issues the authorization information and service configuration of the ONUs to a service interface disk, and if the License resources are not applied, the master control disk does not issue the authorization information and the service configuration; when the ONUs are replaced, the ONUs are respectively set as class I and class II, wherein the class-I ONUs and an optical line terminal (OLT) belong to the same manufacturer, and the class-II ONUs and the OLT belong to different manufacturers; if the class-I ONUs are replaced or the class-II ONUs are replaced, the replaced ONU and the new ONU do not apply and release the License resources; and if the class-I ONUs and the class-II ONUs are replaced, the replaced ONU releases the License resources before being replaced, and the new ONU applies the License resources. By adoption of the method, the License resources are reasonably utilized, leakage is avoided, and operational cost is reduced.

The invention discloses a method, a device and a system for storing and searching Session information. The storing method comprises the following steps of receiving a request which is sent by a user terminal and is used for writing one Session information, recording the time information for receiving the request, determining the number of first storage devices which are already added in the system before the recorded time information according to the time information when each first storage device is added in the system, generating a numerical value which is used for calculating a modulus and extracting a remainder, extracting the remainder by dividing the generated numerical value by the determined number, taking the obtained remainder as a label of one first storage device, determining a corresponding first storage device, writing the Session information sent by the user terminal in the first storage device, and feeding back the recorded time information corresponding to the Session information and the numerical value which is used for calculating the modulus and extracting the remainder to the user terminal. The accuracy of visiting the Session information by a user is increased.

The invention discloses an LC-L bases serial battery pack balance circuit and a balance method. A serial battery pack consists of n single batteries; the balance circuit comprises (2n+2) MOS tubes, (2n+2) diodes and a LC-L energy storage circuit; the LC-L energy storage circuit comprises an inductor L, a capacitor C, a diode VD and a di / dt suppression circuit; the di / dt suppression circuit comprises a buffer inductor Lb, a resistor Rb and a diode VDb. The first characteristic of the balance circuit is that the whole balance circuit only needs one LC-L energy storage circuit for energy transfer, so that the size of the balance circuit can be greatly reduced; the second characteristic of the balance circuit is that expansion is easy, and number of corresponding MOS tubes only needs to increase or reduce while number of the single batteries of the serial battery pack changes; and the third characteristic of the balance circuit is that balance speed is quick, and balance energy in a charging and discharging process can be directly transferred to low-energy single bodies from high-energy single bodies.
