[0002] There are usually multiple formats for camera videos. For example, analog camera video formats include CVI, TVI, CVBS, AHD, etc. Switching between formats can be achieved by logging into the operation interface of the device and controlling the corresponding menu when the device is running. However, it is more difficult to switch when the device is not running. After connecting to the XVR (hard disk recorder), the default video format of the camera may not be recognized by the XVR, resulting in the inability to display the camera screen normally, and the inability to operate the switching format, causing difficulties in on-site application.

However, the above solution adds a dip switch to the tail, making the tail more complicated. In the design of the tail and on-site installation, the reliability of the dip switch, such as waterproof and anti-aging, needs to be considered, which will also increase the cost.

[0031] Embodiment 1

[0032] In this embodiment, at least one movable end is arranged inside the power receiving interface of the camera, and the movable end is mounted on a movable end fixing platform inside the power receiving interface; the power receiving interface also includes a power source, and the movable end is not in contact with the power source in the original state.

[0033] In this embodiment, optionally, if at least two movable ends are provided inside the power receiving interface, the lengths of the at least two movable ends are different, so that the at least two movable ends contact the power source at different times during the insertion of the power adapter output port.

[0034] Figure 1 A schematic diagram of a power supply interface of a camera provided in Embodiment 1 of the present invention.

[0035] The camera may be an analog camera or a digital camera. Figure 1 As shown, the tail end of the camera is the power receiving interface of the camera, and the power receiving interface includes nV power inside. Figure 2 A schematic diagram of an output port of a power adapter provided in Embodiment 1 of the present invention.

[0036] Figure 3A A cross-sectional schematic diagram of a power adapter output port inserted into a power receiving interface provided in Embodiment 1 of the present invention. Among them, the camera tail line terminal T1 is the power receiving interface of the camera, the adapter power terminal P1 is the power adapter output port, L1-L4 are 4 movable terminals of different lengths (L1>L2>L3>L4), L1-L4 are installed on the movable terminal fixing platform inside the power receiving interface, and the distance between L1-L4 and the tail end of the power receiving interface is different; the power receiving interface also includes nV power supply, and L1-L4 are not in contact with the power supply in the original state. Figure 3AAs shown, when the power adapter output port P1 is inserted into the power receiving interface T1, L1-L4 contact P1 successively, and P1 pushes L1-L4 in turn to contact the power supply inside T1 at different times.

[0037] Figure 3B A cross-sectional schematic diagram of another power adapter output port inserted into a power receiving interface provided in Embodiment 1 of the present invention. Among them, the camera tail line terminal T1 is the power receiving interface of the camera, the adapter power terminal P1 is the power adapter output port, L1-L4 are 4 movable terminals of different lengths (L1>L2>L3>L4), L1-L4 are installed on the movable terminal fixing platform inside the power receiving interface, and the distance between L1-L4 and the tail end of the power receiving interface is the same; the power receiving interface also includes nV power supply, and L1-L4 are not in contact with the power supply in the original state. Figure 3B As shown, when the power adapter output port P1 is inserted into the power receiving interface T1, L1-L4 contact P1 at the same time, and P1 simultaneously pushes L1-L4 to contact the power supply inside T1 at different times. There are grooves of different depths inside the power supply, and the depth of the grooves corresponding to different movable ends is equal to the length difference between the movable end and the shortest movable end, so that P1 can simultaneously push L1-L4 to contact the power supply inside T1 at different times.

[0038] In this embodiment, optionally, a limiting mechanism is provided inside the power receiving interface of the camera to determine the contact information between the power adapter output port and the movable end based on the contact information between the power adapter output port and the limiting mechanism during the process of inserting the power receiving interface.

[0039] The limiting mechanism may be an elastic device with a convex shape on the inner wall structure of the power receiving interface. Exemplarily, the elastic device may be a rubber or plastic component. In this embodiment, by setting the limiting mechanism as an elastic device with a convex shape, after each movable end contacts the power inside the power receiving interface, a resistance can be set for the output port of the power adapter inserted into the power receiving interface, and at the same time, the output port of the power adapter can overcome the resistance and continue to move forward.

[0040] In this embodiment, Figure 3A As shown, in order to facilitate on-site operation, a limiting mechanism can also be set inside the power receiving interface of the camera. The limiting mechanism can be used to determine the contact information between the power adapter output port P1 and the movable ends L1-L4 according to the contact information between the power adapter output port P1 and the limiting mechanism during the process of inserting the power receiving interface T1, and can use the state of different numbers of movable ends being pushed to facilitate the user's perception.

[0041] The contact information between the power adapter output port and the limit mechanism can be the unique identification information of the limit mechanism, that is, through the contact information between the power adapter output port and the limit mechanism, it can be known which limit mechanism the power adapter output port contacts, thereby making it easy for the user to perceive the states where different numbers of movable ends are pushed. The contact information between the power adapter output port and the movable end can be the unique identification information of the movable end, that is, through the contact information between the power adapter output port and the movable end, it can be known which movable end the power adapter output port contacts.

[0042] Through such an arrangement, the present scheme sets a limit mechanism inside the power receiving interface of the camera, and can quickly and accurately determine the contact information between the output port of the power adapter and the movable end according to the contact information between the output port of the power adapter and the limit mechanism during the process of inserting the output port of the power adapter into the power receiving interface, thereby conveniently playing a prompt role.

[0043] In this embodiment, optionally, the installation position of the limiting mechanism is determined according to the distance between the movable end and the rear end of the power receiving interface of the power source; the installation quantity of the limiting mechanism is determined according to the quantity of the movable ends.

[0044] For example, Figure 3A For example, a limiting mechanism is added inside T1, so that after P1 is pushed into T1 and pushes L1 to contact the power supply inside T1, it stops due to the resistance of the limiting mechanism. At this time, a slightly larger pushing force is required to continue to push P1, and after P1 pushes L2 to contact the power supply inside T1, it stops again due to the resistance of the limiting mechanism. By analogy, only by applying a slightly larger pushing force can P1 overcome the limiting mechanism and continue to move forward. In order to achieve the above functions, three sets of limiting mechanisms need to be set in the spatial position, and the distance between the lower part of the limiting mechanism and the tail end of the power receiving interface is determined according to the distance between the movable end and the tail end of the power receiving interface when the movable end contacts the power supply inside the power receiving interface.

[0045] In this embodiment, optionally, a jacket spring or spring is configured on the movable end, and the other end of the jacket spring or spring is fixed on the movable end fixing platform, which is used to restore the initial position of the movable end after the power adapter output port exits the power receiving interface.

[0046] In this embodiment, if the application scenario that requires changing the video format is only when the camera is installed for the first time, the movable end may not have the position recovery capability. In order to improve the applicability and flexibility of the technical solution to different application scenarios, a jacket spring or a spring sheet may be configured on the movable end, and the other end of the jacket spring or spring sheet may be fixed on the movable end fixing platform, so that the movable end has the position recovery capability, that is, when the power adapter output port is unplugged from the power receiving interface, the movable end can be restored to the initial position to facilitate the next use. Figure 4 FIG. 1 is a schematic diagram of a movable terminal position recovery method provided in Embodiment 1 of the present invention. Figure 4 As shown, a spring is configured on the movable end, and the other end of the spring is fixed on the movable end fixing platform, which can be used to restore the initial position of the movable end after the power adapter output port exits the power receiving interface.

[0047] Through such an arrangement, the present solution configures a jacket spring or spring sheet on the movable end, and fixes the other end of the jacket spring or spring sheet on the movable end fixing platform. It can be used to restore the initial position of the movable end after the power adapter output port exits the power receiving interface, thereby solving the problem of adding a dip switch to the tail line in the prior art, and the dip switch is only used once when the camera is installed and is no longer used subsequently, but the subsequent dip switch needs to be on the tail line all the time, making the tail line complicated. Therefore, the present solution can be applicable to a variety of application scenarios for switching video formats, thereby improving the applicability and flexibility of the present solution.

[0048] Embodiment 2

[0049] Figure 5 This is a flowchart of a method for switching camera video formats provided in the second embodiment of the present invention. This embodiment is applicable to the case of switching camera video formats. The method can be executed by a switching device for camera video formats. The switching device for camera video formats can be implemented in the form of hardware and / or software. The switching device for camera video formats can be configured in an electronic device with data processing capabilities. Figure 5 As shown, the method includes:

[0050] S110, obtaining electric potential information on at least one movable terminal; wherein the electric potential information on at least one movable terminal is controlled by a change in the depth of the power adapter output port inserted into the power receiving interface.

[0051] In this embodiment, first, the potential information on at least one movable terminal is obtained, wherein the potential information may be potential state information (used to characterize a specific value of the potential, such as 0V or nV) or potential change information (used to describe a change in the potential state information, such as from 0V to nV).

[0052] It should be noted that the potential information on the movable end is controlled by the change in the depth of the power adapter output port inserted into the power receiving interface. Figure 3A or Figure 3B For example, when the power adapter output port P1 is inserted into the power receiving interface T1, the insertion depth can be controlled so that part or all of the movable end contacts the nV power supply inside the power receiving interface T1, so that the potential on the movable end contacting the power supply inside the power receiving interface T1 changes from the original 0V to nV.

[0053] In this embodiment, optionally, the electric potential information on the movable end is controlled by the output port of the power adapter being inserted into the power receiving interface and contacting the movable end, thereby pushing the movable end to move and contact the power inside the power receiving interface.

[0054] like Figure 3A As shown in the figure, when P1 is inserted into T1, different insertion depths of P1 will push the movable terminals L1, L2, L3 and L4 installed on the movable terminal fixed platform in sequence. Based on the length relationship of L1-L4, as P1 is inserted, the movable terminal of L1 is pushed first, causing it to contact the nV power supply inside T1, and causing the potential of L1 to change to nV. By analogy, L2, L3 and L4 contact the nV power supply inside T1 in sequence, and causing the potentials of L2, L3 and L4 to change to nV in sequence.

[0055] Specifically, during the entire insertion process, P1 first contacts L1 and pushes L1 to contact the nV power supply inside T1, so that the potential of L1 changes from 0V to nV; then P1 contacts L2 and pushes L2 to contact the nV power supply inside T1, so that the potential of L2 changes from 0V to nV, and the potential of L1 remains at nV during this process; then P1 contacts L3 and pushes L3 to contact the nV power supply inside T1, so that the potential of L3 changes from 0V to nV, and the potentials of L1 and L2 remain at nV during this process; finally, P1 contacts L4 and pushes L4 to contact the nV power supply inside T1, so that the potential of L4 changes from 0V to nV, and the potentials of L1, L2 and L3 remain at nV during this process.

[0056] S120: Based on a pre-established mapping relationship between the electrical potential information of the movable terminal and the candidate video formats, determine a target video format to be switched according to the electrical potential information on at least one movable terminal.

[0057] In this embodiment, after obtaining the electric potential information of at least one movable terminal, the target video format to be switched can be determined according to the electric potential information of at least one movable terminal based on the pre-established mapping relationship between the electric potential information of the movable terminal and the candidate video formats. Figure 3AFor example (the movable end is L1-L4), assuming that the camera is an analog camera, its corresponding candidate video formats are TVI, CVI, CVBS, and AHD. If the potential state information is used as the potential information, the mapping relationship between the movable end potential information and the candidate video formats can be set as shown in Table 1:

[0058] Table 1 Mapping relationship between movable terminal potential information and candidate video formats

[0059]

[0060] In this embodiment, optionally, based on a pre-established mapping relationship between the electrical potential information of the movable terminals and the candidate video formats, the target video format to be switched is determined according to the electrical potential information on at least one movable terminal, including: determining the number of target movable terminals according to the electrical potential information on at least one movable terminal; and determining the target video format to be switched according to the number of target movable terminals based on the mapping relationship.

[0061] The target movable terminal may be a movable terminal whose electric potential state information changes (such as electric potential increases). Figure 3A For example, if the number of target movable terminals is determined to be 1 according to the potential state information on L1-L4, the target video format to be switched can be determined to be TVI based on the mapping relationship in Table 1; if the number of target movable terminals is determined to be 2 according to the potential state information on L1-L4, the target video format to be switched can be determined to be CVI based on the mapping relationship in Table 1; if the number of target movable terminals is determined to be 3 according to the potential state information on L1-L4, the target video format to be switched can be determined to be CVBS based on the mapping relationship in Table 1; if the number of target movable terminals is determined to be 4 according to the potential state information on L1-L4, the target video format to be switched can be determined to be AHD based on the mapping relationship in Table 1.

[0062] Through such a setting, the present solution can quickly and accurately determine the target video format to be switched based on the mapping relationship between the movable terminal potential information and the candidate video formats and according to the number of target movable terminals determined by the potential information on the movable terminal.

[0063] In the present embodiment, optionally, a pre-established mapping relationship between the movable terminal electric potential information and the candidate video formats is a mapping relationship between a movable terminal identifier whose movable terminal electric potential information changes and the candidate video formats; accordingly, based on the pre-established mapping relationship between the movable terminal electric potential information and the candidate video formats, a target video format to be switched is determined according to the electric potential information on at least one movable terminal, including: determining a target movable terminal identifier according to information on changes in electric potential on at least one movable terminal; and determining the target video format to be switched according to the target movable terminal identifier based on the mapping relationship.

[0064] The target movable terminal identifier can be used to uniquely characterize the target movable terminal. Figure 3A or Figure 3B For example, the target mobile terminal identifier may refer to L1, L2, L3 and L4. Figure 3A For example, if the target movable terminal is identified as L1 according to the change information of the electric potential on L1-L4, the target video format to be switched can be determined as TVI based on the mapping relationship in Table 1; if the target movable terminal is identified as L1 and L2 according to the change information of the electric potential on L1-L4, the target video format to be switched can be determined as CVI based on the mapping relationship in Table 1; if the target movable terminal is identified as L1, L2 and L3 according to the change information of the electric potential on L1-L4, the target video format to be switched can be determined as CVBS based on the mapping relationship in Table 1; if the target movable terminal is identified as L1, L2, L3 and L4 according to the change information of the electric potential on L1-L4, the target video format to be switched can be determined as AHD based on the mapping relationship in Table 1.

[0065] Through such a setting, the present solution can quickly and accurately determine the target video format to be switched based on the mapping relationship between the movable terminal potential information and the candidate video formats and according to the target movable terminal identifier determined by the potential change information on the movable terminal.

[0066] The technical solution of the embodiment of the present invention first obtains the electric potential information on at least one movable terminal; wherein the electric potential information on at least one movable terminal is controlled by the change in the depth of the power adapter output port inserted into the power receiving interface; then based on the pre-established mapping relationship between the electric potential information of the movable terminal and the candidate video formats, the target video format to be switched is determined according to the electric potential information on at least one movable terminal. This technical solution can simplify the tail line of the camera that needs to switch the video format, avoid the reliability problems such as waterproofing and anti-aging caused by the complexity of the tail line, and can quickly, accurately and at low cost switch the video format of the camera without adding additional hardware peripherals, while making the tail line of the camera more beautiful.

[0070] The target video standard determination module 220 is used to determine the target video standard to be switched according to the potential information on the at least one movable terminal based on the pre-established mapping relationship between the movable terminal potential information and the candidate video standards.

[0071] Optionally, the electric potential information on the movable end is controlled by the output port of the power adapter being inserted into the power receiving interface and contacting the movable end, thereby pushing the movable end to move and contact the power inside the power receiving interface.
