Step 21: one network hard disk video recorder is selected from the plurality of network hard disk video recorders to be set as a host, and other network hard disk video recorders are set as slaves.
The user can trigger a button on a certain network hard disk video recorder in the equipment access system to start the operation of selecting one network hard disk video recorder from all the network hard disk video recorders as a host; if it is determined that a certain network hard disk recorder in the system is a master, the remaining network hard disk recorders other than the master are slaves.
Step 22: and acquiring response information from the network camera and the slave by using the host.
After selecting the host in the system, the host may send the collected information to all the slaves and the network camera, where the collected information is used to identify the receiver (including the slaves and the network camera) and feedback response information after receiving the collected information, where the response information includes information about the slaves/network camera, such as: address, device type, serial number or device capabilities, etc.
Step 23: the host computer is used for generating a pairing table based on the response information.
After receiving the response information sent by the slave and the network camera, the host can pair the network camera with the network hard disk video recorder to generate a pairing table, wherein the pairing table comprises the pairing relation between the network camera and the network hard disk video recorder; for example, the system includes 3 network hard disk recorders and 2 network cameras, which are respectively denoted as A1-A3 and B1-B2, the network hard disk recorder A2 is a host, the idle channels of the network hard disk recorder A1 are 5, the idle channels of the network hard disk recorder A2 are 6, and the idle channels of the network hard disk recorder A3 are 4, so that the host can establish a pairing relationship between the network camera B1 and the network hard disk recorder A2 and a pairing relationship between the network camera B2 and the network hard disk recorder A1 to form a pairing table.

After the host generates the pairing table, the pairing table can be sent to the slave so that the slave and the host can add corresponding network cameras by using the pairing table; for example, the pairing table includes a plurality of pieces of pairing information, and if a certain piece of pairing information is that the second channel of the network hard disk video recorder C is paired with the network camera D, after the network hard disk video recorder C receives the pairing table, the network hard disk video recorder C finds the information matched with the pairing table in the pairing table by using the name of the network hard disk video recorder C as an index value, and then adds the network camera D to the second channel of the network hard disk video recorder C.
According to the method for automatically adding the network camera, one network hard disk video recorder can be selected as a host, then the host collects information of all the slaves and the network video cameras, the host can generate a pairing table by utilizing the collected information to form a pairing relationship between the network video cameras and the network hard disk video recorders, and the established pairing table is issued to the slaves, so that the slaves and the host can add corresponding network video cameras according to the pairing table, and the automatic addition of the network video cameras by the network hard disk video recorders is realized; because a certain network hard disk video recorder can be used for distributing resources, the resource coordination among a plurality of network hard disk video recorders can be solved, one network video recorder can be added only by one network hard disk video recorder, and certain network video cameras can not be omitted from being added, so that the stability of a system is improved.
Referring to fig. 3, fig. 3 is a flowchart of another embodiment of a method for automatically adding a network camera provided in the present application, where the method is applied to the device access system in the above embodiment, and the device access system includes a network camera and a plurality of network hard disk recorders, and the method includes:
step 301: initializing all the network hard disk video recorders to enable the states of the network hard disk video recorders to be the first states.
The initial state of all the network hard disk video recorders is the first state, and a user can manually operate a switch on the network hard disk video recorders to generate an automatic adding instruction to initiate a pairing process.
Step 302: and taking the network hard disk video recorder which receives the automatic adding instruction as election initiating equipment, and setting the state of the election initiating equipment to be a second state.
The network hard disk recorder that initiates the pairing process may be referred to as an election initiating device, which may set its own state to the second state.
Step 303: and broadcasting the search packet in a preset time by using the election initiating equipment, so that the network camera and the network hard disk video recorder send response information to the election initiating equipment after receiving the search packet.
A time window period (i.e. preset time) can be set, and the network hard disk video recorder in the second state can periodically broadcast/multicast a search packet in the preset time to search, so as to obtain all equipment information in the local area network where the network hard disk video recorder is located; specifically, if a network hard disk video recorder in a second state exists in the system, the network hard disk video recorder is election initiating equipment and is a host; if there are two or more network hard disk recorders in the second state in the system, there are other network hard disk recorders in the second state besides the election initiating device.
Further, the response information comprises equipment attribute information and resource capability information, the equipment attribute information comprises equipment addresses, equipment types or serial numbers of equipment, the equipment addresses comprise addresses of network cameras and addresses of network hard disk recorders, the equipment types comprise the network cameras, the network hard disk recorders or the ball machines, and the serial numbers of the equipment comprise the serial numbers of the network cameras and the network hard disk recorders; the resource capability information includes first resource capability information corresponding to the slave, the first resource capability information including a decoding resolution capability set, a supported number of ways corresponding to the decoding resolution capability set, a maximum access bandwidth, a maximum number of access ways, or added network camera information, and second resource capability information corresponding to the network camera, the second resource capability information including a current resolution, a current code stream, a resolution capability set, and a code stream range, the resolution capability set including at least one resolution, the code stream range including at least one code stream value.
After receiving the search packet, the network hard disk video recorder in the first state changes the state of the network hard disk video recorder from the first state to a third state and sends a response message to the election initiating equipment; after receiving the search packet, the network hard disk recorder in the second state determines whether to send a response message to the election initiating device based on the own serial number and the serial number of the election initiating device, and a specific scheme will be described below.
Step 304: and recording the network hard disk video recorder in the second state as a candidate host, and selecting the host based on the number of the candidate hosts and the serial numbers of the candidate hosts.
In order to select one host in the case of two or more candidate hosts, the steps shown in fig. 4 may be adopted, which specifically include:
step 3041: and judging whether the number of the candidate hosts is larger than a preset number.
In order to select one network hard disk recorder from all network hard disk recorders as a host, the preset number may be 1, i.e., determine whether the number of candidate hosts is greater than 1.
Step 3042: if the number of the candidate hosts is larger than the preset number, selecting the candidate host with the smallest serial number from all the candidate hosts as the host.
The candidate host that received the search packet may be referred to as a current candidate host, and the current candidate host may determine whether the sequence number of the current candidate host is smaller than the sequence number of the candidate host (referred to as a sender) broadcasting the search packet; if the serial number of the current candidate host is smaller than the serial number of the sender, modifying the state of the current candidate host into a third state, and stopping broadcasting the search packet; if the serial number of the current candidate host is greater than or equal to the serial number of the sender, the current candidate host continues broadcasting the search packet; repeating the steps until the number of the candidate hosts is a preset number. When the network hard disk video recorder in the second state is detected to exist, comparing the sizes of the serial numbers, modifying the state of the network hard disk video recorder with the smaller serial number into a third state by the network hard disk video recorder with the smaller serial number, and terminating the action of broadcasting/multicasting the search packet in the preset time; and the network hard disk video recorders with larger serial numbers continue to broadcast/multicast search packets to search and receive response information until only one network hard disk video recorder with the second state is in the local area network, the state of the searched equipment is in the third state, the network hard disk video recorder with the second state is recorded as a host, and the network hard disk video recorder with the third state is recorded as a slave.
It will be appreciated that the candidate host with the largest sequence number among all candidate hosts may be selected as the host, or the candidate host with the largest remaining idle channels among all candidate hosts may be selected as the host, or the hosts may be selected according to other reasonable rules.
Step 3043: and if the number of the candidate hosts is smaller than or equal to the preset number, taking the election initiating equipment as the host.
If the number of the candidate hosts is only one, the network hard disk video recorder with the second state is indicated to be only one in the system, and the network hard disk video recorder is used as the host.
The pairing relation and the adding strategy can be formulated according to the equipment system resources and the capabilities of the network hard disk video recorder (comprising a host machine and a slave machine) and the network video camera, and the formulation principle of the pairing relation is as follows: 1) A network camera can only be added by a network hard disk video recorder and can only be added once and cannot be repeated; 2) The network video camera is preferentially distributed to the network video recorder with the resolution and the code stream size matched with the network video camera, so that after the network video camera is accessed, the network video recorder can normally display the video which is matched with the resolution of the network video camera, and the code stream size does not exceed the maximum access bandwidth of the network video recorder; 3) If the current resolution or the current code stream size of the network camera cannot be matched with the access performance and the decoding performance of the network hard disk video recorder, switching and adjusting are carried out according to the resolution capability set and the code stream range of the network camera, so that the performance matching of the two is achieved; 4) When the accessible path numbers of all the network hard disk video recorders are inconsistent with the total number of the network video cameras, recording the information of the network video recorders on idle accessible channels or unassigned network video cameras; the specific embodiments will be described below.
Step 305: and judging whether the current resolution of the current network camera is contained in the decoding resolution capability set of the current network hard disk video recorder.
It can be determined whether the current resolution of the current network camera is the same as a value in the decoding resolution set of the current network hard disk recorder.
Step 306: if the current resolution of the current network camera is contained in the decoding resolution capability set of the current network hard disk video recorder, a pairing relation between the current network camera and the current network hard disk video recorder is established and stored in a pairing table.
If the decoding resolution capability set of the current network hard disk video recorder contains the current resolution of the current network video camera, the current resolution of the current network video camera is the same as the decoding capability of the current network hard disk video recorder, and at the moment, the host establishes a pairing relation between the current network video camera and the current network hard disk video recorder and stores the pairing relation.
Further, whether to establish the pairing relation between the current network camera and the current network hard disk video recorder can be determined according to the number of supporting paths of the network camera; for example, assuming that the network video recorders are denoted as H1 and H2, and their support routes are 16 and 8, respectively, when pairing is performed, the network video camera H1 and 16 network video cameras may be paired, and the network video camera H2 and 8 network video cameras may be paired, that is, the network video cameras H1 and H2 are allocated according to the ratio of the support routes.
Step 307: and if the current resolution of the current network video camera is not contained in the decoding resolution set of the current network video recorder, selecting other network video recorders as the current network video recorder.
If the decoding resolution capability set of the current network hard disk video recorder does not contain the current resolution of the current network video camera, selecting other network hard disk video recorders to perform matching judgment, namely selecting other network hard disk video recorders as the current network hard disk video recorders, and returning to execute the step 305 until all network hard disk video recorders are traversed or the decoding resolution capability set of the current network hard disk video recorders contains the current resolution of the current network video camera.
If the decoding resolution capability sets of all the network hard disk video recorders are found to not contain the current resolution of the current network video camera after traversing all the network hard disk video recorders, that is, when the current resolution of the current network video camera is different from the resolution in the decoding resolution capability set of each network hard disk video recorder, the current resolution can be adjusted based on the resolution capability set of the current network video camera.
Further, the decoding resolution capability set comprises the maximum decoding resolution, and whether a network hard disk video recorder with an idle channel exists or not is judged; if the network hard disk video recorder with the idle channel exists, the network hard disk video recorder with the idle channel is recorded as a network hard disk video recorder to be selected, the network hard disk video recorder to be selected with the smallest difference value between the maximum decoding resolution and the current resolution in all the network hard disk video recorders to be selected is selected as the network hard disk video recorder matched with the current network video camera, the maximum decoding resolution of the network hard disk video recorder matched with the current network video camera is recorded as the preset resolution, the current resolution is adjusted to the preset resolution, and the resource adjustment information is generated.
For example, the resolution capability set includes 3 resolutions: {480p,720p,1080p }, the code stream range includes 2 code stream sizes: {512Kbps,1024Kbps }, assuming that the decoding resolution capability set of the current network hard disk video recorder is 1080P, the maximum access bandwidth of the current network video camera is 720Kbps, the current resolution is 1080P, and the current code stream is 1024Kbps, the host can adjust the current resolution of the current network video camera to 720P, and generate resource adjustment information, and because the current code stream is the same as the maximum access bandwidth, adjustment on the current code stream is not needed.
In one embodiment, when selecting a network hard disk recorder paired with a current network camera, a resolution matching policy and a code stream adjustment policy may be used as follows:
1) Resolution matching strategy
a. Grading according to the maximum decoding resolution of all network hard disk recorders, and dividing all network hard disk recorders into at least one group, for example, as shown in fig. 5, dividing all network hard disk recorders into X groups and Z groups, wherein the X groups comprise { NVR1, NVR1}, the maximum decoding resolution of the X groups is 4k, the Z groups comprise { NVR2, NVR4}, and the maximum decoding resolution of the Z groups is 1080P; it will be appreciated that the grouping may be one or more depending on the maximum decoding capability, and may be based on the particular application requirements.
b. All network cameras are divided into groups according to the maximum decodable resolution of the network hard disk recorder, for example, as shown in fig. 5, all network cameras are divided into three groups with 4K and 1080P as boundaries: group a, group B and group C.
c. Preferentially processing the packets with the lowest resolution, taking as an example in fig. 5, the network cameras of the group C are allocated to the network hard disk recorders of the group Z, and if the number of all the network cameras of the group C is more than the sum of the channels of all the network hard disk recorders of the group Z, adding the network cameras of the group C to the group X; if the number of all network cameras in the group C is smaller than the sum of the channels of all network hard disk video recorders in the group Z, the information of the network hard disk video recorders with idle channels in the group Z is recorded, so that when the number of channels in the group X is insufficient for the network cameras in the group A or the group B, the idle channels in the group Z can be used as paired equipment after the resolution of the network cameras in the group A or the group B is reduced.
d. C, sequentially and upwardly distributing network hard disk video recorders according to the sequence of the maximum decodable resolution, taking fig. 5 as an example, for the network hard disk video recorders of the X groups, firstly adding redundant network video cameras of the C groups which are not added by the Z groups and network video cameras of the B groups, if channels of the network hard disk video recorders of the X groups are remained, then downwards regulating the current resolution of the network video cameras of the A groups to 4K, and establishing a pairing relation with the remained idle channels of the network hard disk video recorders of the X groups; if the network video cameras in the partial A group are not added by the network video recorders, firstly confirming whether the network video recorders with the resolution higher than the maximum decodable resolution of the X group exist, if so, distributing according to the step c, if not, downwards confirming whether the network video recorders with the higher decoding specification have the rest free channels in the Z group, and if so, reducing the current resolution of the network video cameras in the A group to 1080P to be added to the Z group.
In summary, the network cameras are allocated in the order from bottom to top according to the current resolution of the network cameras, the network cameras are more than one to confirm whether the rest free channels exist according to the order from top to bottom, and if yes, the current resolution is reduced to allocate.
2) Code stream adjustment strategy
Acquiring the sum of current code streams of all network cameras, and recording the sum as the sum of the code streams; then judging whether the sum of the code streams is larger than the sum of the maximum access bandwidths of all the network video recorders; and if the sum of the code streams is larger than the sum of the maximum access bandwidths of all the network video recorders, adjusting the current code stream of each network video camera.
Further, the product of the current code stream of the current network camera and the sum of the maximum access bandwidth can be calculated and is recorded as a first product; calculating the product of the current total bandwidth and a preset redundancy coefficient, and recording the product as a first product, wherein the preset redundancy coefficient is used for ensuring the stability of the system and can be set according to an empirical value; judging whether the ratio of the first product to the first product is larger than the minimum value of the code stream range of the current network camera; if the ratio of the first product to the first product is larger than the minimum value of the code stream range of the current network camera, taking the minimum value of the code stream range of the current network camera as a preset code stream, and adding the preset code stream into the resource adjustment information; if the ratio of the first product to the first product is smaller than or equal to the minimum value of the code stream range of the current network camera, taking the ratio of the first product to the first product as a preset code stream, and adding the preset code stream to the resource adjustment information.
In another specific embodiment, the coding configuration parameters include a current code stream and a current resolution, and the coding information includes a maximum access path number and a maximum access bandwidth; judging whether the network hard disk video recorders with the same coding configuration parameters as the current network video cameras exist in the coding information of all the network hard disk video recorders or not; if the network hard disk video recorders with the same coding configuration parameters as the current network video cameras exist in the coding information of all the network hard disk video recorders, selecting the network hard disk video recorder with the largest idle channel, the smallest serial number or the largest serial number as the network hard disk video recorder matched with the current network video cameras, and establishing a pairing relation between the current network video cameras and the network hard disk video recorders; if the network hard disk video recorders with the same coding configuration parameters as the current network video cameras do not exist in the coding information of all the network hard disk video recorders, determining the corresponding current network hard disk video recorders to be matched based on the resolution capability set and the code stream range of the current network video cameras, selecting the network hard disk video recorder with the smallest difference value between the coding configuration parameters of the current network video cameras and the network hard disk video recorders within the capability range of the network hard disk video recorders as the network hard disk video recorder matched with the current network video cameras, namely, setting the resolution with the smallest difference value between the resolution capability set of the current network video cameras and the largest decoding resolution of the current network hard disk video cameras as the preset resolution, and generating resource adjustment information; and taking a code stream which is smaller than/equal to the maximum access bandwidth of the current network hard disk video recorder and has the smallest difference value with the maximum access bandwidth of the current network hard disk video recorder in the code stream range of the current network video camera as a preset code stream, and adding the preset code stream into resource adjustment information, wherein the resource adjustment information comprises the steps of adjusting the current resolution of the current network video camera to the preset resolution and/or adjusting the current code stream of the current network video camera to the preset code stream.
Step 308: and the host sends the pairing table to the network hard disk video recorder so that the network hard disk video recorder executes an automatic adding task based on the pairing table to finish adding the corresponding network video camera.
After generating the pairing table, the host can send the pairing table to the slave so as to enable the host and the slave to add a network camera matched with the pairing table by using the pairing table; specifically, the network hard disk video recorder comprises a plurality of channels for connecting with the network video camera; the host can judge whether the sum of the maximum access paths of all the network hard disk video recorders is the same as the number of all the network cameras; if the sum of the maximum access paths of all the network hard disk video recorders is different from the number of all the network video cameras, the fact that at least one network hard disk video recorder has residual idle channels is indicated, or at least one network video camera cannot be added by the network hard disk video recorders, for convenience of subsequent management, the host can record the number of the residual idle channels of the network hard disk video recorders or information of the network video cameras which are not allocated, wherein the information of the network video cameras which are not allocated comprises serial numbers or addresses of the network video cameras which do not establish a pairing relation with the channels of any network hard disk video recorder.
Step 309: when the resource adjustment information exists, the host computer sends the resource adjustment information to the network hard disk video recorder corresponding to the resource adjustment information, so that the network hard disk video recorder corresponding to the resource adjustment information adjusts the encoding configuration parameters of the paired network video camera.
If the host computer adjusts the encoding configuration parameters of the network camera, that is, the resource adjustment information is generated, the host computer or the slave computer can adjust the current resolution and the current code stream of the network camera paired with the host computer according to whether the resource adjustment information is carried.
Step 310: after the automatic adding task is completed, the host and the slave send adding adjustment information to the host; and the host computer counts the adding adjustment information sent by all the slaves to generate a statistic table.
