Example

[0074] Specific application example one
[0075] The management platform defines faults or abnormal events as follows:
[0076] Event A: disconnect;
[0077] Relevant parameters for determining event A: Maximum detection period: X seconds;
[0078] The management platform sends the defined events and their parameters to the wireless sensor network gateway.
[0079] The wireless sensor network gateway monitors and detects the wireless sensor network terminal connected to the wireless sensor network gateway during the detection period. The wireless sensor network gateway sets the detection period T according to the received event-related parameters, and the value of T is equal to or less than the maximum detection period: X. The detection method can be as follows:
[0080] 3.1. Set a timer Timer1 with a timing length of T seconds, and start Timer1 at the beginning of each detection cycle to send detection information to the wireless sensor network terminal. After receiving the detection information, the wireless sensor network terminal The wireless sensor network gateway sends an online feedback message, which can be a control signaling from the terminal to the gateway. If at the end of the detection period and when the timer Timer1 expires, the online feedback message of the wireless sensor network terminal is still not received, it is determined that it is disconnected.
[0081] 3.2. The wireless sensor network gateway starts a timer Timer2 with the detection time for each wireless sensor network terminal, and the timing length is T seconds. If the timer Timer2 expires, it does not receive a certain wireless sensor. Any signaling or data from the network terminal is determined to be disconnected. If the signaling or data of the wireless sensor network terminal is received within the timer Timer2, the timer Timer2 is restarted.
[0082] 3.3. The wireless sensor network gateway sends the maximum detection period X (in seconds) to the wireless sensor network terminal. The wireless sensor network terminal sets a timer Timer3 locally, and the timing length is equal to or less than the maximum detection period X seconds. When Timer3 expires, it sends online indication information to the wireless sensor network gateway and restarts Timer3. The wireless sensor network gateway also starts a timer Timer4 locally. The duration can be equal to or less than the maximum detection period. The duration of Timer4 must not be less than the duration of Timer3. If the timer Timer4 expires, no online instructions from the wireless sensor network terminal are received. It is judged to be disconnected.
[0083] When the wireless sensor network terminal needs to disconnect normally, it sends an offline instruction to the wireless sensor network gateway, and the wireless sensor network gateway no longer monitors and detects the terminal.
[0084] 4. Once the wireless sensor network gateway detects that a wireless sensor network terminal is disconnected, it reports the fault or abnormal event to the management platform. The report content includes: the occurrence of the fault or abnormal event: event A, wireless sensor network terminal identification: WSN_UE_ID, or/and the time of the fault or abnormal event: 2010-5-27 13:53, or/and the fault or abnormal event Location: (X, Y), where X, Y are the longitude and latitude coordinates of the terminal, or the ID of the wireless sensor gateway: WSN_GW_ID.
[0085] 5. After receiving the report sent by the wireless sensor network gateway, the management platform immediately informs the user of the wireless sensor network terminal of the information. The notification method may be that the management platform sends an alarm message to the short message management center, and the short message management center sends the alarm information to the user.

Example

[0086] Specific application example 2:
[0087] The management platform defines faults or abnormal events as follows:
[0088] Event B: Illegal movement. This event applies to the location of the wireless sensor network terminal when the terminal user signs up. Such as vending machine monitoring settings, parking lot monitoring equipment, etc.
[0089] Relevant parameters for determining event B: contracted location information, which is a location range, expressed in latitude and longitude coordinates (X1-X2, Y1-Y2), where X1 is less than X2, and Y1 is less than Y2.
[0090] The corresponding processing method: deny terminal access, or reduce the resources provided to the terminal, or perform detachment of the terminal.
[0091] 2. The management platform sends the events to be monitored, related parameters, or/and processing methods after the events occur to the wireless sensor network gateway.
[0092] 3. The wireless sensor network gateway monitors and detects the connected wireless sensor network terminal according to the parameters related to the received event. The event detection method is as follows:
[0093] 3.1. If each wireless sensor network terminal includes a GPS positioning module, the location information can be used as part of the request signaling when requesting access, where the location information is the longitude and latitude coordinates (X, Y) of the terminal. When the wireless sensor network gateway receives the request, it determines whether the location information (X, Y) in the access request is within the range defined by the event-related parameters. The specific method for determining is to compare whether the longitude X of the terminal is in the event-related parameters. Between X1 and X2, and compare whether the latitude Y of the terminal is between Y1 and Y2 of the event-related parameters. If the value of X is less than X1 or greater than X2, or the value of Y is less than Y1 or greater than Y2, then the location of the terminal is considered Beyond the defined range, the terminal is determined to be an illegal move.
[0094] 3.2. When the wireless sensor network terminal requests access for the first time, the wireless sensor network gateway saves its location information (Xa, Ya). In the subsequent access of the terminal, the terminal still needs to include the current location information (Xb, Yb) in the access request, and the wireless sensor network gateway can compare the location information (Xb, Yb) in the access request with the previous Whether the location information (Xa, Ya) of one access matches, the specific comparison method is whether Xb is greater than or equal to Xa-m and less than or equal to Xa+m, and whether Yb is greater than or equal to Ya-m and less than or equal to Ya+m, where m It is the position statistical error margin value, indicating that the position deviation within this range is acceptable, and the management platform or the user server does not update its position information, it is judged as an illegal movement.
[0095] 4. Once the wireless sensor network gateway detects an illegal movement of a wireless sensor network terminal, it will report the failure or abnormal event to the management platform. The report content includes: the occurrence of the failure or abnormal event: event B (illegal movement) , Wireless sensor network terminal identification: WSN_UE_ID, or/and the time when the fault or abnormal event occurs: 2010-5-27 10:48, or/and the place where the fault or abnormal event occurs: latitude and longitude coordinates or wireless sensor gateway identification WSN_GW_ID ; Or when the gateway has locally received the corresponding processing method for the event sent by the management platform, it performs the operation according to the processing method, that is, denies the terminal's access, or reduces the resources provided to the terminal, or executes the terminal Deattach.
[0096] 5. After receiving the report sent by the wireless sensor network gateway, the management platform can send the corresponding processing method of the event to the wireless sensor network gateway.
[0097] 6. The wireless sensor network gateway performs operations according to the corresponding processing method of the received event, that is, denies the terminal's access, or reduces the resources provided to the terminal, or performs detachment of the terminal.
