In the step S102, optimization, if the terminal is made an inventory, initiation message also includes mode indication information of making an inventory, When the mode indication information of making an inventory is designated as long disk mode, base station is made an inventory end message receiving the terminal from application layer After be immediately finished terminal bay dot pattern, when the mode indication information of making an inventory is designated as fast disk mode, base station is according to the end Duration information timing of making an inventory in end plate point initiation message terminates terminal bay dot pattern or is receiving the terminal bay from application layer Terminal bay dot pattern is immediately finished after point end message.It is to enter long disk mould that the mode indication information of making an inventory, which is used to indicate base station, Formula or fast disk mode: (1) base station enter long disk mode after, it will execute by turns subsequent step S103 and S105~ S106 ceaselessly collects making an inventory from wireless terminal and data and returns to application layer, make an inventory knot until receiving the terminal Just stop after beam message (its producing method can make an inventory with the terminal initiation message consistent)；(2) base station is entering fast disk mode Afterwards, it will periodically execute subsequent step S103 and S105~S106, i.e., periodically collect the data of making an inventory from wireless terminal And application layer is returned to, when timing (countdown or along timing), which reaches, makes an inventory duration or receives terminal end of making an inventory and disappear Just stop (can terminating in advance) after breath.By both modes, it regularly or aperiodically can carry out terminal and make an inventory, it is full Sufficient flexible Application demand.

S103. base station broadcast terminal on waking up channel is made an inventory wakeup message, wherein the terminal is made an inventory wakeup message packet Information and password information are selected containing password authentication, the password authentication selection information is used to indicate corresponding with the password information Password unique identification.

In the step S103, the terminal makes an inventory wakeup message for the wireless terminal that wake-up period is slept, and to Wireless terminal provides password authentication selection information and password information for waking up verification, so that wireless terminal voluntarily identifies whether It is waken up by legitimate base station.In addition, mobilism and randomization in order to realize password verification, optimization, the end is being broadcasted in base station Before end plate point wakeup message, a pair of password authentication selection information and password letter are randomly choosed from local storage Breath.

In the step S103, ensures that and wake up all wireless terminals, optimization, base station is on waking up channel And within the first period continuity the multiple terminals of periodic broadcasting make an inventory wakeup message, wherein first period when The long sleep cycle for being greater than wireless terminal, when the sleep cycle includes period sleep time and the period awakening of wireless terminal Long, the make an inventory broadcast cycle of wakeup message of the terminal is less than the period awakening duration of wireless terminal.Due to first period Duration be greater than the sleep cycle of wireless terminal and the make an inventory broadcast cycle of wakeup message of the terminal is less than wireless terminal Period awakening duration, it can be ensured that wireless terminal can completely receive institute in the period awakening duration of any one sleep cycle It states label to make an inventory wakeup message, prevents to occur waking up to omit.Citing, if a length of 100ms, the period stop when period awakening A length of 3900ms when dormancy, then the sleep cycle of wireless terminal is 4 seconds, and the broadcast cycle may be designed as 60ms (assuming that the end A length of 50ms when the transmission of end plate point wakeup message reserves the time slot spacing of 10ms), the duration of first period may be designed as 4020ms can continuously broadcast 67 terminals and make an inventory wakeup message.It advanced optimizes, the terminal is made an inventory wakeup message It also include the first period duration information and current message tranmitting data register information, wherein the current message tranmitting data register information It is used to indicate from the initial time of the first period to the timestamp of current message sending instant.It is configured by aforementioned information, nothing Line terminal is after obtaining the first period duration information and current message tranmitting data register information, it is known that terminal described in epicycle The broadcast-end-time of wakeup message made an inventory it is possible thereby to which a longer dormancy time is arranged is conducive to wireless terminal energy conservation, especially It is for completed terminal make an inventory response message feedback wireless terminal (may be simply referred to as wireless terminal of having made an inventory) for, by It makes an inventory response message in no longer needing to pass the terminal, wakes up again after can directly sleeping broadcast.

In the step S103, since terminal wakeup message of making an inventory can externally inform it by message Frame Properties For broadcast message, therefore for wireless terminal, it may not be necessary to know that the terminal is made an inventory the identity of the sender of wakeup message And/or recipient's identity, therefore optimize, terminal wakeup message of making an inventory also may include source address invalid bit and/or wide Broadcast address invalid bit, wherein the source address invalid bit is used to indicate makes an inventory in wakeup message there is no source in the terminal Location information, the broadcast address invalid bit, which is used to indicate, makes an inventory in wakeup message in the terminal there is no broadcast address information, The source address information is used to indicate the terminal and makes an inventory the identity of the sender of wakeup message, and the broadcast address information is for referring to Show that the terminal is made an inventory recipient's identity of wakeup message.It is made an inventory the address default configuration of wakeup message by aforementioned terminals, it can It is mentioned with effectively shortening message-length (can generally shorten 4 bytes or 8 bytes) and transmission duration not only conducive to base station transmission energy conservation High channel utilization rate, can also effectively shorten the wake-up channel sense duration of wireless terminal, further be conducive to wireless terminal energy conservation.

S104. wireless terminal is made an inventory after wakeup message receiving the terminal, first selects information according to the password authentication The correspondence password content prestored is searched in local storage, then judges whether the password content found is believed with the password Breath is consistent, is made an inventory response message by channel competition mechanism to base station feedback terminal in responsive channels if consistent, is otherwise refused Lost art is answered, wherein terminal response message of making an inventory includes terminal address information and terminal bay point data information, the terminal Location information, which is used to indicate, to be sent the terminal and makes an inventory the wireless terminal of response message.

In the step S104, the corresponding relationship of the password authentication selection information and password content is preset at conjunction in advance In the wireless terminal of method, and information and the password information are selected with the password authentication being preset in legitimate base station in advance Corresponding relationship is consistent, and since aforementioned corresponding relationship is not preset in pseudo-base station, wireless terminal can be voluntarily according to password The check results of content and password information determine whether the base station for initiating wakeup message is legal, and only just allow when confirming legal Reaction plate point data is responded, it is possible thereby to effectively evade the security risk that " pseudo-base station " steals data of making an inventory, realization was being interacted The purpose of data safety is ensured in journey.In addition, the dedicated channel different from the wake-up channel, institute can be selected in the responsive channels State terminal bay point data information and can be, but not limited to include equipment alarm data zone information, petroleum technology equipment area information and/or Device sensor acquires data zone information etc..

Before the step S104, in order to further ensure that the password authentication selection information and/or password letter The transmission safety of breath, prevents from being intercepted in the air by other " hacker " websites, it is therefore necessary to carry out encryption guarantor to aforementioned important information Shield, that is, optimize, and base station is made an inventory in the broadcast terminal before wakeup message, and a kind of encryption calculation is randomly choosed from local storage Method/and encryption key select information and/or the password information to encrypt the password authentication, and make an inventory in the terminal It include that the first Encryption Algorithm selection information/and the first encryption key select information in wakeup message, wherein first encryption Algorithms selection information is used to indicate to be used during encrypting the password authentication selection information and/or the password information The algorithm unique identification of Encryption Algorithm, the first encryption key selection information, which is used to indicate, is encrypting the password authentication selection The key unique identification of used encryption key during information and/or the password information；Wireless terminal receive it is described Terminal is made an inventory after wakeup message, first selects information to search the correspondence prestored in local storage according to first Encryption Algorithm Decipherment algorithm/and according to first encryption key select information the correspondence decruption key prestored is searched in local storage, Then the password authentication selection information and/or the password are obtained using the decipherment algorithm found/and decryption key decryption Information.Wherein, the corresponding relationship of the first Encryption Algorithm selection information and decipherment algorithm is preset at legal wireless end in advance In end, and the corresponding relationship with first Encryption Algorithm selection information and Encryption Algorithm that are preset in legitimate base station in advance Match；The corresponding relationship of the first encryption key selection information and decruption key is preset in advance in legal wireless terminal, and It is matched with first encryption key selection information being preset in legitimate base station in advance with the corresponding relationship of encryption key.Due to " hacker " website cannot predict aforementioned corresponding relationship in advance, thus be difficult to crack to obtain the password authentication selection information and/or The password information can further promote safety.

In the step S104, in order to solve collision problem in the presence of magnanimity terminal inventory procedure it is obvious and The problems such as controlling progress of inventory checking is slow, optimization, the terminal make an inventory wakeup message also include end packet instruction information；Wireless terminal It makes an inventory after wakeup message receiving the terminal, using the end packet number of end packet instruction information instruction to local Terminal ID number carry out complementation calculating, then according to complementation calculated result determine where end packet, finally with place terminal It is grouped in corresponding responsive channels, is made an inventory response message by channel competition mechanism to base station feedback terminal.Due to wireless terminal End packet where can voluntarily determining and only the reaction plate point data in responsive channels corresponding with place end packet, can be with Magnanimity wireless terminal point is subjected to data upload in different channels, realizes the mesh for concurrently uploading data and reduction collision probability , and then the task of making an inventory of all wireless terminals can be rapidly completed.Such as there are the scene of making an inventory of 1000 wireless terminals, The end packet number can be designed as to 4, and then magnanimity label can be divided into 4 groups, every group theoretically there are 250 wireless ends End, and make them the competition in 4 different responsive channels uploads the terminal and makes an inventory response message respectively, it is possible thereby to realize 4 Lu Bingchuan data and the purpose for reducing collision probability.In addition, the corresponding relationship of the responsive channels and end packet can pass through mark Quasi- agreement default can also make an inventory in the terminal and be specified in wakeup message, such as the end packet for being 0 for remainder, Specified first responsive channels；The end packet for being 1 for remainder specifies the second responsive channels；The terminal point for being 2 for remainder Group specifies third responsive channels, etc..

S105. base station receives the terminal by listening to responsive channels and makes an inventory response message.

Before the step S105, in order to further ensure that the terminal address information and/or the terminal inventory count It is believed that the transmission safety of breath, prevents from being intercepted in the air by other " hacker " websites, it is therefore necessary to also carry out aforementioned important information Encipherment protection optimizes, wireless terminal is made an inventory in the transmission terminal before response message, randomly chooses from local storage A kind of Encryption Algorithm/and encryption key encrypt the terminal address information and/or the terminal bay point data information, and Making an inventory in response message in the terminal includes that the second Encryption Algorithm selection information/and the second encryption key select information, In, the second Encryption Algorithm selection information, which is used to indicate, is encrypting the terminal address information and/or the terminal inventory count It is believed that during breath used Encryption Algorithm algorithm unique identification, second encryption key selects information to be used to indicate The key for encrypting used encryption key during the terminal address information and/or the terminal bay point data information is unique Mark；Base station is made an inventory after response message receiving the terminal, first selects information to deposit locally according to second Encryption Algorithm The correspondence decipherment algorithm/prestored is searched in storage area and selects information to search in local storage according to second encryption key Then the correspondence decruption key prestored obtains the terminal address using the decipherment algorithm found/and decryption key decryption and believes Breath and/or the terminal bay point data information.Wherein, the corresponding relationship of the selection of the second Encryption Algorithm information and Encryption Algorithm It is preset in legal wireless terminal in advance, and selects information with second Encryption Algorithm being preset in legitimate base station in advance It is matched with the corresponding relationship of decipherment algorithm；The corresponding relationship of the second encryption key selection information and encryption key is preset in advance In legal wireless terminal, and it is close with second encryption key selection information being preset in legitimate base station in advance and decryption The corresponding relationship of key matches.Since " hacker " website cannot predict aforementioned corresponding relationship in advance, it is difficult to crack to obtain described Terminal address information and/or the terminal bay point data information, can further promote safety.
