Description
Technical Field
The application belongs to the technical field of monitoring systems, and particularly relates to a method for acquiring the online state of front-end equipment.
Background
In the video monitoring field system, the front-end equipment is mostly developed and communicated based on the SIP protocol specified by GB/T28181. According to the GB/T28181 standard, the online state information is stored in directory data. When the system (the system can be a terminal or an upper platform server) needs to acquire the online state of the front-end equipment in real time, the existing mechanism mostly adopts to send a catalog owner (the catalog owner can be the front-end equipment or the platform server connected with the front-end equipment) first, and the catalog owner returns all the catalog data of the front-end equipment owned by the catalog owner based on the request. After receiving all node directory data, the system sends a directory subscription request to a directory owner. After receiving the request, the catalog owner actively transmits catalog notification to the system when the online state of the front-end equipment is changed, so that the function of acquiring the online state of the front-end equipment in real time is realized.
However, when the number of front-end equipment nodes of the directory owner is large, the problem that the online state acquired by the system is incorrect may exist in this way. The reason is that when the number of front-end equipment nodes of the catalog owner is large, the amount of catalog data to be sent is also large, and a certain time is required for sending to be completed. During this transmission, the directory owner has not received a directory subscription request, and if the presence status of the head-end equipment changes, the directory owner does not notify the system, resulting in incorrect presence status obtained by the system.
The Chinese patent No. CN201410384194.X discloses a front-end application monitoring method, comprising the following steps: when the terminal equipment runs a front-end application through a browser, the front-end application monitors the running state of the terminal equipment; when the front-end application monitors that the current running state meets the reporting triggering condition, the front-end application acquires data corresponding to the current running state, and reports the acquired data to a Web server through a reporting agency in a preset format, so that the Web server regulates the data, then sends the regulated data to a monitoring server, and the monitoring server carries out corresponding processing according to the regulated data. The embodiment of the application also discloses a front-end application and a monitoring system of the front-end application. By implementing the embodiment of the application, the front-end application can actively report the running condition, and the efficiency of finding the problem of the front-end application is improved. But does not take into account that if the number of head-end nodes is large, the data sent to the system may not be consistent with the current state of the head-end, resulting in an incorrect state being acquired by the system.
The application of China is patent CN200810061115.6, a front-end processor control system of a general monitoring system is disclosed, the front-end processor control system is used for polling a scanning acquisition end, storing scanned data to the front-end processor, a rear-end processor is communicated with the front-end processor to acquire or set an embedded microprocessor of the acquisition end data under the front-end processor, the embedded microprocessor comprises a defined digital switching value, the front-end processor actively initiates communication, and the front-end processor responds, and adopts a one-to-one mode, wherein a data frame format comprises: a start flag, a frame header, content, a check code, and an end flag; normal data inquiry is carried out, the digital switching value output by the acquisition end is set, the alarm parameter up-down value of the acquisition end is set, the input switching state quantity of the acquisition end is set by the front-end machine, and the configuration of all parameters of the acquisition end is set. The front end machine control system of the universal monitoring system has good expansibility, reduces cost and avoids waste when the production scale is increased. However, the one-to-one method requires a relatively long time, and cannot meet the demand.
