Embodiment
In view of this, the invention provides a kind of radio switch-in method of IPC equipment, to solve the larger and ineffective problem of the difficulty of IPC equipment wireless access.
The present invention is by making the function of NVR (network hard disk video recorder) integration of equipments AP (WAP (wireless access point)), NVR equipment is usingd self system data as a parameter of default cryptographic algorithm, generate wireless network access authentication information, this authentication information is with changing every day system data; And IPC equipment generates the cryptographic algorithm identical with NVR equipment by setting in advance and the system data of self wireless network access authentication information and sends to NVR equipment; The described authentication information that wherein IPC equipment sends is also with changing every day system data; NVR equipment compares the wireless network access authentication information of the wireless network access authentication information of the IPC equipment of receiving and self generation, if identical, allows described IPC equipment access wireless network, otherwise does not allow this IPC equipment access wireless network.Therefore the present invention can make IPC equipment and NVR equipment generate identical wireless network access authentication information according to identical algorithm and parameter, thereby make in the automatic access of radio network of IPC equipment, without user's manual operation, reduced the difficulty of IPC equipment wireless access, and a plurality of IPC equipment can access simultaneously, and then has improved operating efficiency.
Below in conjunction with Figure of description, the embodiment of the radio switch-in method of a kind of IPC equipment provided by the invention is elaborated.
Refer to Fig. 1, the process chart of the radio switch-in method of a kind of IPC equipment provided by the invention, described method is applied to supervisory control system, and described supervisory control system comprises NVR equipment, IPC equipment, the function of described NVR integration of equipments AP, described method comprises step:
101, NVR equipment is usingd self system data as a parameter of default cryptographic algorithm, generates wireless network access authentication information, and this authentication information is with changing every day system data;
Wherein, in the micro radio LAN such as NVR equipment and IPC equipment main services Yu Ru family, office, in this network, conventionally possess a gateway device and be connected with spider lines, NVR equipment and IPC equipment are by wireless connections network, so just need to an AP be set between gateway and IPC equipment, as the bridge that is connected with spider lines and wireless network.In order to simplify this supervisory control system, the embodiment of the present invention is integrated and start the function of AP on NVR equipment, and IPC equipment is carried out to wireless access authentication.
The embodiment of the present invention is usingd system data of NVR equipment self as a parameter of default cryptographic algorithm, generates wireless network access authentication information.
102, IPC equipment adopts the cryptographic algorithm identical with NVR equipment set in advance, and the system data of himself as the parameter of cryptographic algorithm, generate wireless network access authentication information, and send described wireless network access authentication information to described NVR equipment; This authentication information is with changing its every day system data;
Described IPC equipment also can adopt the cryptographic algorithm identical with NVR equipment setting in advance, and usings himself system data as the parameter of cryptographic algorithm, the wireless network access authentication information of generation.Emphasize that cryptographic algorithm and parameter that described NVR equipment and IPC equipment are used must be identical herein, otherwise the two cannot generate identical wireless network access authentication information.Cryptographic algorithm can set in advance in equipment, as MD5 (Message Digest Algorithm 5) algorithm, or similar cryptographic algorithm.
In order to guarantee that IPC equipment is identical with the parameter of the cryptographic algorithm of NVR equipment, and the authentication information generating for the IPC equipment with follow-up access keeps synchronizeing, IPC equipment in the present invention and NVR equipment are used system data as the parameter of cryptographic algorithm, because system data is the unified time, no matter IPC equipment or the system data of NVR equipment are all synchronous so, so the wireless network access authentication information generating is identical certainly.Use another advantage of system data to be, the system data of equipment can upgrade every day, wireless network access authentication information on IPC equipment and NVR equipment also can be upgraded and change with date every day so, so, the IPC equipment of follow-up access still can be used its system data to generate wireless network access authentication information with the default cryptographic algorithm identical with NVR equipment, and identical with the authentication information of NVR equipment.Here it should be noted that system data is accurate to " day ", such as on July 20th, 2014, need not be accurate to " hour ".
Generally, the system data of each equipment is consistent.But in order to prevent some fortuitous events, the embodiment of the present invention can be by NVR equipment to IPC equipment date of shipping sync message.This date sync message can be the SSID broadcasting packet that NVR equipment carries self system data.IPC equipment receives after this broadcasting packet, just can carry out the date according to the system data of NVR equipment wherein synchronous.
