Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. indicate an orientation or a positional relationship based on that shown in the drawings or that the product of the present invention is used as it is, this is only for convenience of description and simplification of the description, and it does not indicate or imply that the device or the element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
The current part of the gun type, barrel type, ball type and other network cameras are externally transmitted and configured with an optical port network, the cameras are provided with an optical module and an optical port, the optical module is used for converting network electric signals into optical signals, and the optical port plays a role of fixing the optical module.
Generally, a camera is generally fixedly labeled with a hundred-megabyte optical module or a gigabit optical module, where the hundred-megabyte optical module adopts a hundred-megabyte optical fiber communication mode, and the gigabit optical module adopts a gigabit optical fiber communication mode, but since optical fiber communication does not have a hundred-megabyte adaptive switching compatibility principle, an optical module at a camera end must correspond to a switch or a docking end one to one, for example, please refer to fig. 1, fig. 1 is an optical fiber communication scene schematic diagram provided by an embodiment of the present invention, as shown in fig. 1, a gigabit optical module in a network camera can normally communicate with a gigabit optical module in a switch or a docking end, and similarly, a hundred-megabyte optical module in a network camera can normally communicate with a hundred-megabyte optical module in a switch or a docking end, otherwise, a communication abnormality occurs.
Based on the scenario diagram shown in fig. 1, it can be deduced that different configurations between the camera and the switch or the docking end affect the communication between the two as shown in table 1.
TABLE 1
As can be seen from the above fig. 1 and table 1, because the optical fiber communication mode is not adaptive and downward compatible, an optical port may be mistakenly used to cause failure in communication, and particularly, a single board test and a complete machine test may easily cause a pairing error and failure in communication during production, which wastes time and energy to replace and disassemble, and for a user at a docking end, when a certain gigabit optical fiber switch (because the switch fixes a certain optical fiber communication mode) is used at the docking end, but a camera device only supports a hundred-megabyte optical module, the device may not be communicated because of being unable to adaptively switch, which affects use experience.
Referring to fig. 2, fig. 2 is a functional block diagram of a camera according to an embodiment of the present invention, the camera 100 includes: the optical network interface comprises a main control system module 101, an optical port communication circuit module 102 and a network port communication circuit module 102, wherein the main control system module 101 is electrically connected with the optical port communication circuit module 102 and the network port communication circuit module 102 respectively.
The master control system module 101 may include: the processor and the storage module reset module are used as a core processor to play the roles of detecting logic reality, storing abnormal alarm records, resetting and clearing and the like.
The optical port communication circuit module 102 may include: an optical port chip or a configuration circuit with an optical port SWITCH, an I2C expansion chip, an optical port chip or a configuration circuit with an optical port SWITCH, an EEPROM memory circuit, an optical port and an optical module.
The optical interface communication circuit module 102 may obtain optical module information according to the 2C expansion chip, obtain optical module information of the SWITCH or the docking terminal through the network interface, SWITCH an optical interface PHY or SWITCH operating mode with the optical interface according to the detection comparison information, and have functions of power-down memory, repeated detection memory, and the like to assist in completing detection comparison processes in various complex scene modes.
It is understood that the optical port communication circuit module 102 can be directly installed in the camera as a separate circuit module, and the configured EEPROM memory circuit plays a role in storing the communication identification information and saving power.
In one possible embodiment, the EEPROM stores a relational table as shown in table 2.
TABLE 2
That is, IPC network camera devices such as a bolt, etc. leave the factory without an optical module, the communication identification information of the EEPROM is 3; IPC network camera devices such as a cone camera and a dome camera leave a factory, and are provided with an optical module, if the optical module is a hundred-megabyte optical module, the communication identification information of the EEPROM is 1, and if the optical module is a giga-megabyte optical module, the communication identification information of the EEPROM is 2.
It should be noted that, the numerical value of the communication identification information is only used to distinguish different communication modes, in the embodiment of the present invention, the communication identification information corresponding to the network port communication mode is denoted by 3, the communication identification corresponding to the hundred-megabyte optical fiber communication mode is denoted by 1, and the communication identification information corresponding to the giga-fiber communication mode is denoted by 2, and a user may also distinguish different communication modes by other numerical values or characters according to actual needs, which is not limited herein.
The portal communication circuit module 103 may include: network interface chip or SWITCH chip with optical port, network interface; the method comprises the steps that firstly, when the situation that an optical module is inserted and an EEPROM non-standard bit enters S4 is detected, the network port is communicated and detected with opposite-end equipment through a configuration network port, and information of the opposite-end optical port and the optical module is confirmed, so that the optical module is compared and configured to meet an optical communication mode; and the second function is to judge that the abnormal communication jumps to a corresponding processing flow mode when the abnormal communication of the optical port occurs and the repeated network cable plugging is detected under the mode of S3-S7 or S4-S7, so as to avoid abnormal dead circulation of the communication.
Remarking: the IPC network camera is fixed by the IP and passively waits for the communication of the other party, and the detection process is carried out after the IPC network camera is connected and communicated with a switch or a butt joint end. In addition, attention is paid to the fact that an isolation mechanism is needed to be arranged on the network port and the optical port, and network storms caused by direct connection of the network port and the optical port are prevented.
As can be seen from fig. 2, the camera 100 may further include other functional modules, such as an abnormal alarm circuit module, which may include a Flash storage circuit, a voice alarm circuit, a light supplement lamp alarm circuit, and a serial port circuit, and is configured to provide an abnormal alarm message for a user to prompt a user to replace an abnormal optical module, an unconnected optical fiber, or an unmatched optical module for retesting.
In combination with the camera shown in fig. 2, in order to implement flexible switching of the communication mode, the main control system module 101 may be configured to execute the communication control method in the embodiment of the present invention, so as to implement network port communication with a target communication object through the network port communication circuit module, or implement optical port communication with the target communication object through the optical port communication circuit module.
With reference to the above-mentioned camera, a communication mode control method according to an embodiment of the present invention is described below, where the camera shown in fig. 1 is taken as an execution main body of the communication mode control method, please refer to fig. 3, and fig. 3 is a schematic flowchart of the communication mode control method according to the embodiment of the present invention, where the method includes:
and S301, when the optical module access signal is not detected or the read communication identification information is a first set value, communicating with a target communication object through the internet access.
The optical module access signal refers to a signal generated when a user accesses an optical module into an optical port of a camera. When the camera is inserted into the optical module, the optical module is in place, the access signal can be detected, and when the camera is not inserted into the optical module, the optical module is not in place, and the access signal is not detected.
The target communication object may be, but is not limited to, a switch.
The communication identification information corresponds to different communication modes, the camera can communicate through a network port or an optical port, and an optical module is configured in the camera which communicates through the optical port, for example, if the camera leaves a factory and is not configured with the optical module, the camera communicates with an exchanger or a butt-joint end through the network port; if the optical module is configured, an optical port or a network port can be used for communication according to actual communication requirements.
It can be understood that different types of optical modules correspond to different optical fiber communication modes, for example, a hundred-megabyte optical module corresponds to a hundred-megabyte optical fiber communication mode, and a gigabit optical module corresponds to a gigabit optical communication model.
In the embodiment of the present invention, if the camera is self-provided with the optical module when leaving the factory, the communication identifier information of the camera is configured to be the third setting value or the second setting value, which indicates that the camera can communicate through the optical fiber communication mode, and if the communication identifier information is read to be null, it indicates that the user has triggered the reset operation module of the camera (for example, the user presses the reset key for 10 seconds, etc.), which causes the communication identifier information to be cleared, in this case, the network port communication mode may be configured, thereby ensuring that the communication is normal.
In step S301, the first setting value corresponds to an internet access communication mode, and the embodiment of the present invention further sets a second setting value and a third setting value to distinguish different optical fiber communication modes.
And S302, when the optical module access signal is detected, reading the communication identification information.
And S303, if the communication identification information is empty, when the network cable connection signal is detected, determining a target optical fiber communication mode, and communicating with a target communication object through an optical port based on the target optical fiber communication mode.
In the embodiment of the present invention, if the communication identification information is empty, the optical fiber communication cannot be performed by determining the optical fiber communication mode through the communication identification information, so that after the network cable connection signal is detected, the communication detection can be performed through the network port, thereby achieving the effect of determining the target optical fiber communication mode.
And S304, if the communication identification information is not empty and is not a first set value, communicating with the target communication object through the optical port based on a preset optical fiber communication mode corresponding to the communication identification information.
In the embodiment of the present invention, the first setting value corresponds to a network port communication mode, and the second setting value and the third setting value correspond to different optical fiber communication modes, for example, the second setting value is 1 and corresponds to a hundred-megabyte optical fiber communication mode, the third setting value is 2 and corresponds to a gigabit optical fiber communication mode, and the third setting value is 3 and corresponds to a network port communication mode.
If the communication identification information is not empty and is not the first set value, it indicates that the accessible communication identification information is the third set value or the second set value, and at this time, communication can be performed through the optical port directly according to the optical fiber communication mode corresponding to the read communication identification information.
Then, in a possible implementation, the step S304 may be performed as follows:
if the communication identification information is a second set value, the hundred-million optical module corresponding to the second set value is used for communicating with a target communication object through an optical port;
and if the communication identification information is the third set value, the communication is carried out with the target communication object through the network port based on the gigabit optical module corresponding to the third set value.
According to the communication mode control method provided by the embodiment of the invention, the optical fiber communication mode can be not fixedly limited, the optical fiber communication mode matched with the target communication object can be adaptively switched for communication, and the problem that the optical module needs to be dismounted and replaced under the condition of abnormal communication can be solved.
To understand the foregoing process of determining the target optical fiber communication mode in an aspect, the following provides a possible implementation manner, please refer to fig. 4, where fig. 4 is a schematic flowchart of step S303 provided in an embodiment of the present invention, and step S303 may include:
and S303-1, outputting network cable connection prompt information and reading preset optical module information if the communication identification information is empty.
The network cable connection prompt message can be used for indicating a user to connect the network cable at the moment so as to trigger the communication detection through the network port, and the user can carry out network cable connection according to the network cable connection prompt message.
It should be noted that after the network cable connection prompt information is output, the optical module information in the camera may be read at this time, and the optical module information may include an optical module type and a corresponding optical fiber communication mode.
And S303-2, if the network cable connection signal is detected, acquiring the optical module information of the target communication object through the network port.
In the embodiment of the present invention, if a network cable connection is detected, it is equivalent to triggering a processing procedure for determining a target optical fiber communication mode, and at this time, in a case where the network cable is normally connected, the optical module information of the target communication object may be acquired by communicating with the target object through the network port.
And S303-3, if the optical module information of the target communication object is matched with the preset optical module information, determining that the preset optical fiber communication mode is the target optical fiber communication mode, and communicating with the target communication object through an optical port based on the target optical fiber communication mode.
If the optical fiber communication mode of the target communication object is consistent with the preset optical fiber communication mode, it is indicated that the optical modules of the camera correspond to the optical modules of the target object one to one, and if the optical communication mode is consistent with the optical communication mode, the preset optical fiber communication mode (which may also be the optical fiber communication mode of the target object) can be used as the target optical fiber communication mode, and optical port communication is performed based on the target optical fiber communication mode.
S303-4, if the optical module information of the target communication object is not matched with the preset optical module information, outputting alarm prompt information, and after detecting the replacement operation of the optical module, executing the steps of determining a target optical fiber communication mode and communicating with the target communication object through an optical port based on the target optical fiber communication mode;
and the alarm prompt information is used for indicating a user to replace the optical module.
For example, assuming that the camera configuration and the target object configuration are both a hundred mega optical module, the target optical fiber communication mode may be determined to be a hundred mega optical fiber communication mode; if the hundred-megabyte optical module configured by the camera and the gigabit optical module configured by the target object are assumed, the optical modules are determined to be inconsistent at the moment, alarm information is output, and after a user obtains the alarm information, the hundred-megabyte optical module can be replaced by the gigabit optical module, and then the gigabit optical fiber communication mode is determined to be the target optical fiber communication mode.
As can be seen from the above embodiments, normal communication between both parties cannot be realized by the above embodiments without knowing both the optical communication mode and the optical module.
In an optional embodiment, because the current function differences of various types of cameras are different, multiple alarm modes need to be supported, so that the embodiment of the present invention provides the following alarm prompting modes:
the first method is as follows: the online internet access alarm is displayed on a web page of the network camera and corresponding log information is printed to prompt an alarm;
the second method comprises the following steps: sound is output to broadcast alarm information through an audio alarm circuit to prompt alarm;
the third method comprises the following steps: different light information is output to the outside through a light supplement lamp alarm to prompt an alarm;
the method is as follows: log prompt information is output externally through serial port printing information to give an alarm.
In an optional implementation manner, in the process of communication through an optical interface, communication abnormality may be caused because an optical module configured by a camera is not matched with an optical module of a target communication object.
Scene one: and performing communication based on the determined target optical fiber communication mode, wherein communication abnormity occurs.
If the first scenario occurs, after the step S303, the method shown in fig. 4 may be included, please refer to fig. 5, where fig. 5 is a schematic flowchart of another communication mode control method provided in the embodiment of the present invention, and the method further includes:
s305, if the network cable plugging signals of the preset times are detected in the preset time period or the optical fiber connection is determined to be failed, determining that the communication is abnormal, and outputting alarm prompt information.
In the embodiment of the invention, as the camera is in a state of passively waiting for communication, communication abnormity occurs, the camera cannot be adjusted in time, and an external trigger condition is needed to prompt the camera to complete the confirmation of the optical fiber communication mode and improve the abnormal communication condition.
It should be noted that the operation of plugging and unplugging the network cable in the embodiment of the present invention is only one of the trigger conditions, and the user may also set another trigger condition to trigger the camera to execute a procedure of determining the target optical fiber communication mode and communicating with the target communication object through the optical port based on the target optical fiber communication mode.
It can be seen that, in step S303, communication is performed when the optical fiber communication mode of the camera matches the optical communication mode of the target communication object, and if communication is abnormal, it indicates that the optical module of the camera is damaged or the optical fiber is not connected, but since the camera is in a passive communication state, it cannot be determined that the communication is the cause of the abnormality, the camera may be triggered to recognize the abnormality by a trigger condition, that is, a network cable plugging/unplugging signal, and then remedial measures are taken.
S307, if the optical module replacement operation instruction is not detected within a preset time period or the optical fiber access signal is not detected, stopping the communication process and updating the communication identification information to a first set value;
and S308, if an optical module replacement operation instruction is detected within a preset time period or an optical fiber access signal is detected, determining a target optical fiber communication mode, and communicating with a target communication object through an optical port based on the target optical fiber communication mode.
Scene two: and communication abnormity occurs based on the communication of the preset optical fiber communication mode corresponding to the communication identification information.
If scenario two occurs, after the step S304, the method shown in fig. 6 may be included, please refer to fig. 6, where fig. 6 is a schematic flowchart of another communication mode control method according to an embodiment of the present invention, and the method further includes:
s309, if the network cable plugging signals of preset times are detected in a preset time period or the optical fiber connection is determined to be failed, determining that the communication is abnormal;
and S310, when the network cable connection signal is detected, determining a target optical fiber communication mode, and communicating with a target communication object through an optical port based on the target optical fiber communication mode and the target optical fiber communication mode.
Through the embodiment, the camera can be triggered to quickly determine the communication abnormity, and quickly respond to the abnormal communication condition, so that the optical communication returns to normal.
In an alternative embodiment, after step S303, the method further comprises:
a1, determining a set value corresponding to a target optical fiber communication mode;
a2, setting the communication identification information as a set value corresponding to the target optical fiber communication mode;
a3, writing the communication identification information into the memory.
For example, if the target fiber optic communication mode is the hundreds of mega fiber optic communication mode, the set value may be determined as the second set value (the second set value may be, but is not limited to, 1), and similarly, if the target fiber optic communication mode is the giga fiber optic communication mode, the set value may be determined as the third set value (the third set value may be, but is not limited to, 2), and then the determined set value is written into the memory, so that it is possible to ensure that the fiber optic communication mode is determined directly from the set values before the next communication.
In an optional embodiment, in order to prevent network storm, a network port isolation mechanism can be configured in the process of communicating with a target communication object through an optical port.
With reference to the communication mode control method provided above, an embodiment of the present invention provides a possible implementation manner of a camera 100 on the basis of fig. 2, please refer to fig. 7, fig. 7 is a schematic diagram of a possible implementation manner of a camera provided in an embodiment of the present invention, as shown in fig. 7, an embodiment of the present invention provides an implementation manner of an optical port communication circuit module 102 and a network port communication circuit module, and a data interaction manner between each functional module in the camera, and with reference to fig. 7, the communication mode control method provided above may be as shown in fig. 8, fig. 8 is a scene schematic diagram of a communication mode control method provided in an embodiment of the present invention, and the communication mode control method may be performed as follows:
