Description

Short message step alarming method for judging channel interruption
Technical Field
The invention relates to a short message ladder alarm method for judging channel interruption, and belongs to the technical field of power systems.
Background
The related data acquisition system in the power dispatching system collects data through communicating with the field acquisition terminal, the direct communication between the data acquisition system and the field acquisition terminal is particularly critical, the data acquisition system can judge the communication state of a channel between the data acquisition system and the acquisition terminal, when the channel is disconnected or returns to normal, the data acquisition system can generate an alarm message, then the alarm message is formed into an alarm short message which is sent to an appointed receiver through a short message module, the receiver can know the connection condition between the data acquisition system and the acquisition terminal at the first time, and related personnel are arranged to perform inspection and maintenance when abnormality occurs.
If the channel is frequently interrupted and restored under a specific environment, for example, the wireless channel is affected by severe weather, a large number of alarm short messages are generated to affect the judgment of a receiver, and meanwhile, the receiver easily ignores the frequent alarm short messages, and the system fault cannot be checked and maintained without a supervision mechanism.
In addition, the related short messages are often sent directly and not divided into time periods, for example, the short messages are sent at night, and when the short messages are received at night, the receiver does not necessarily process the short messages at the first time, and may wait for the working time of the next day to process the short messages, so that the meaning of sending the short messages at the first time is lost. Meanwhile, the short message is sent to a relevant receiver, whether the receiver processes the short message in time cannot be supervised, and the purpose of processing the received short message is lost.
Disclosure of Invention
The invention provides a short message ladder warning method for judging channel interruption, which sets the roles of short message receivers according to the grades, dynamically sets the transmission time intervals among the roles at the same time, and sends short messages layer by layer at a dynamic certain time interval from low to high grades under the condition of channel interruption, thereby playing a monitoring role.
Furthermore, the invention provides a short message ladder alarm method which can intelligently analyze the channel interruption so as to more accurately judge whether the channel interruption is true.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a short message ladder alarm method for judging channel interruption comprises the following steps:
step one, establishing a scene pool: acquiring different communication states of a data acquisition system and an acquisition terminal channel and/or acquiring different communication states of the data acquisition system and the acquisition terminal channel and RSSI (received signal strength indicator), and forming a scene pool;
step two, acquiring an interrupt scene of the current channel in real time, and comparing the interrupt scene with scenes in a scene pool so as to judge whether the interrupt scene of the current channel is a real interrupt or not, wherein if the interrupt scene is the real interrupt, an alarm module sends an alarm message to alarm;
step three, short message ladder alarm; the message receiver of the alarm message comprises three roles of a field operation and maintenance person, a scheduling operation and maintenance person and a scheduling manager with the grades from low to high;
setting time interval between each kind of roles, setting time interval between on-site operation and maintenance person and scheduling operation and maintenance person as t1The time interval between the scheduling operation and maintenance person and the scheduling manager is set as t2(ii) a When the interruption meets the sending condition of the alarm message, the interruption is firstly sent to a field operation and maintenance person, and at t1If the interruption time exceeds t, the alarm message is sent to the scheduling operation and maintenance person1+t2If so, sending the interrupted warning message to a scheduling manager;
t1and t2Is a set value, i.e. t1 startAnd t2 start(ii) a T after1And t2Each channel is associated with an initial t that varies dynamically with channel interrupt frequency1 startAnd t2 startWhen the message is sent for the first time, press t1 startAnd t2 startSending at time intervals, and calculating the off-line rate R of adjacent front and back channels when the scene is frequently interrupted and recovered for a short time later and alarm messages need to be sentFront sideAnd RRear endDifference R ofDifference (D)，RDifference (D)＝RFront side-RRear end；t1According to t1＝(t1-t1×(1-RRear end))+((t1-t1×(1-RRear end))×RDifference (D)) Carrying out ladder transmission; t is t2According to t2＝(t2-t2×(1-RRear end))+((t2-t2×(1-RRear end))×RDifference (D)) And carrying out step transmission.
The scene is recovered after the channel is interrupted for a period of time, and the alarm is sent according to the step, but only the alarm is sentIs pressed against t1 startAnd t2 startSending is carried out, because when the channel off-line rate of recovering the scene after interrupting for a period of time is lower, the calculation t is updated1、t2Is not suitable, and can be triggered when the off-line rate is high (for example, the set value is 90 percent), and then t is updated according to the above formula1、t2。
