Before describing the methods provided by the present disclosure, some concepts will be defined and described with respect to their meaning in the methods provided by the present disclosure.
The NVR (Network Video Recorder), namely a Network Video Recorder, is a storage and forwarding part of a Network Video monitoring system, and the NVR and a Video encoder or a Network camera work cooperatively to complete Video recording, storage and forwarding functions of videos. The camera can be bound on the NVR equipment, and the related information of the camera can be directly acquired through the NVR.
A management platform: the method is used for managing, controlling and monitoring the equipment in the network. The management platform in this disclosure refers to a software component.
GB28281 is the technical requirements of information transmission, exchange and control of a safety protection video monitoring networking system, and is a national standard drafted by multiple units such as the national safety protection alarm system standardization technical committee, the ministry of public security and the like. The standard locates SIP as the primary signaling base protocol for networked systems,
the method is applied to an EPS system, particularly applied to an EPS scanner, the EPS scanner and a Network Video Recorder (NVR) establish communication based on an SIP protocol, the EPS scanner serves as an SIP server, the NVR serves as an SIP client, the EPS scanner accesses the NVR through a specific port, and list information of terminals connected with the NVR, which is stored on the NVR, is acquired. The list information includes an ID of the terminal, a registration method (registry), an IP address, status information of the terminal, a device type, vendor information, and the like. And identifying the equipment information through the acquired list information, and sending the equipment information to the management platform.
Specifically, fig. 1 is a schematic flow chart of a terminal scanning method provided by the present disclosure, and as shown in fig. 1, the method includes:
in step 204, the EPS scanner receives a response of successful registration sent by the NVR.
Before step 202 is executed, address information such as an IP address and port information of the NVR is configured on the EPS, and then the EPS scanner registers (Register) between a specific port in the address information and the NVR through the SIP protocol, and receives a response that the registration is successful, where the response is sent by the NVR. The registration between the EPS scanner and the NVR complies with the registration mode specified by SIP, and details thereof are not repeated herein.
In step 206, the EPS scanner sends an acquisition request of the terminal device directory to the NVR to request list information of the terminal managed by the NVR.
The EPS scanner acquires list information stored by the NVR through catalog, that is, acquires related information of the network device corresponding to the NVR through catalog query.
In the prior art, for a non-public security system video network, the EPS generally directly scans port information of network equipment to acquire equipment information, and compared with the mode, the method disclosed by the invention firstly operates an SIP protocol between an EPS scanner and an NVR and acquires related information of the network equipment in an indirect mode.
In addition, in the prior art, although GB28181 is made, the manufacturers do not comply with the standard, and still adopt their own proprietary protocols, for example, for device information corresponding to the same location in the list information, manufacturer a may store an IP address, and manufacturer B may store a device status. Therefore, the EPS scanner needs to perform further processing on the acquired information after acquiring the list information.
And step 208, after the list information of the terminal is obtained, identifying the equipment information of different manufacturers according to the characteristic fields in the list information, and sending the equipment information to the management platform according to the standard format of communication with the management platform.
Specifically, the vendor information may be identified using the characteristic fields of the various vendors, via step 208. The feature field herein refers to a field that each vendor can distinguish from other vendors. For example, if the vendor a has an IP address with a different format than other vendors, the IP address is the vendor's feature field, and if the vendor B has status information with a different format than other vendors, the status information is the vendor's feature field. Wherein the status information refers to whether the network device is on or off.
Specifically, for example, the IP address of the vendor a is referred to as address, and the IP address of the vendor B is referred to as IP address, so that the two different vendors can be distinguished from each other by the IP address.
After different manufacturers are identified, corresponding equipment information is identified, and the equipment information of the different manufacturers is converted into a standard format and is sent to the management platform. The standard format herein refers to the management protocol running between the EPS scanner and the management platform.
For step 208, one embodiment of identifying vendors is: and judging whether the matched characteristic field exists in the list information according to the corresponding relation between the prestored characteristic field and the manufacturer information, and if so, sending the manufacturer information to the management platform according to a standard format communicated with the management platform.

The EPS scanner in the disclosure re-identifies the acquired list information, converts the list information into a standard format between the list information and the management platform, and sends the standard format to the management platform, so that the management platform can conveniently store and manage the device information.
For information that is not needed by the network management platform, the EPS scanner may filter to reduce the processing load of the management platform, for example, if the EPS scanner determines that the device is in a closed state according to the state information of the device in the list information, the EPS scanner does not report the state information of the device to the management platform.
Generally, the device information that the management platform needs to acquire includes: any one or more of an IP address, status information of a terminal, a device type, vendor information. Wherein the device type may include: cameras, routers, servers, etc. Particularly, the list information of the public security also includes information which is not needed by the management platform, such as a registration mode, and the like, so that the EPS scanner may discard other information except the device information in the list information.
In addition, as the EPS scanner is generally matched with the management platform, the management platform can timely sense the abnormal network device. For example, if the device type changes, it indicates that the network device is fake for the network device with the same IP address. Therefore, the EPS scanner may periodically send an acquisition request of the terminal device directory to the NVR, so that the management platform compares whether the other device information corresponding to the same IP address in the list information acquired this time is the same as that in the list information acquired last time, and determines whether the corresponding device is abnormal.
