[0037] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art based on the present application belong to the scope of protection of the present utility model.

[0038] In recent years, with the increasingly wide application of industrial cameras, the manufacturing of industrial cameras gradually tends to miniaturization and easy installation. In the related art, a POE power supply module is arranged inside the industrial camera to meet the requirement of easy installation. Although the non-isolated POE power supply (Power Over Ethernet, Ethernet power supply) is small in size, it may cause the problem of power supply failure or equipment burning due to power supply and field ground connection. Although the isolated POE is more reliable, the isolated POE transformer is large in size and poor in heat dissipation, and the industrial camera using the isolated POE cannot be miniaturized.

[0039] In some scenarios, due to the small installation space, the industrial camera in the related art is too large in size to meet the requirement of miniaturization and cannot be applied to the scenario with small installation space.

[0040] In order to reduce the size of the industrial camera, the utility model embodiment provides a power supply system of an industrial camera and the industrial camera, which are described in detail as follows:

[0041] The utility model embodiment provides a kind of image acquisition system, including power supply system and industrial camera 100, refer to Figure 1 Including: industrial camera 100, POE module 200, POE switch 300;POE module 200 is located in the shell outside industrial camera 100;

[0042] Industrial camera 100 includes network transformer 101, power module 102;

[0043] The output end of POE switch 300 is connected with the input end of network transformer 101, the power output end of network transformer 101 is connected with the input end of POE module 200, and the output end of POE module 200 is connected with the input end of power module 102.

[0044] POE refers to a technology that transmits data signals for some IP-based terminals while providing DC power supply for such devices without any modification of the existing Ethernet Cat.5 cable infrastructure. POE is also known as power over LAN or active Ethernet, and sometimes simply referred to as Ethernet power supply, which is the latest standard specification for simultaneous transmission of data and electric power by using existing standard Ethernet transmission cables, maintaining compatibility with existing Ethernet systems and users.

[0045] It can be understood that, in addition to the network transformer 101 and the power supply module 102, the industrial camera 100 can further include other functional modules to realize the setting functions of the industrial camera 100, and specific contents of the other functional modules can be referred to related technologies, which are not limited here.

[0046] The POE module 200 is located on the side close to the industrial camera 100 in the power supply system and is located outside the industrial camera 100, which can reduce the space occupation inside the industrial camera 100 and is beneficial to miniaturization of the industrial camera 100.

[0047] The network transformer 101 and the power supply module 102 are internal modules of the industrial camera 100, the power supply module 102 is a power supply control circuit of the industrial camera 100, and can convert the input voltage signal into a voltage signal required for internal work of the industrial camera 100. The POE module 200 is a POE power supply module based on the prior art, in one example, the POE module 200 can be an isolation POE module to improve the safety of power supply. The POE switch 300 is a switch supporting Ethernet power supply based on the POE technology. The POE switch 300 transmits the electric signal of the POE power supply to the network transformer 101 through a network cable (for example, Cat.5), the central tap of the network transformer 101 separates the electric signal and transmits it to the POE module 200 outside the industrial camera 100, and the POE module 200 converts the electric signal into a direct current voltage with a voltage value within the rated working voltage range of the power supply module 102 after rectification, voltage conversion, isolation and other operations, so as to supply power to each power-consuming part in the network user equipment 100 by the power supply module 102.

[0048] The power supply system provided by the embodiment of the utility model reduces the volume of the industrial camera 100 by independently arranging the POE module 200 outside the industrial camera 100, realizes miniaturization of the industrial camera 100, and at the same time, arranging the POE module 200 outside the industrial camera 100 is beneficial to heat dissipation of the POE module 200 and makes the assembly position of the POE module 200 more flexible.

[0049] In a possible implementation, referring toFigure 2 The image acquisition system further comprises a first cable 401 and a second cable 402;

[0052] One end of the fourth interface 504 is connected with the output end of the POE module 200, and the other end of the fourth interface 504 is used for inserting the second cable 402.

[0053] The first cable 401 and the second cable 402 can be common power supply cables, which need to meet the power requirement of POE power supply. The first interface 501 and the second interface 502 are interfaces integrated on the industrial camera 100, and are used for conveniently showing the connection relationship, Figure 2 In the actual application, the third interface 503 and the fourth interface 504 are interfaces integrated in the POE module 200; the positions of the interfaces can be adjusted according to actual needs, and the drawing is only one possible implementation manner of the embodiment of the utility model.

[0054] In a possible implementation manner, referring to FIG. 3(a), the image acquisition system further comprises a third cable 403, the third cable 403 comprises a first sub-cable 4031 and a second sub-cable 4032;

[0055] The industrial camera 100 further comprises a fifth interface 505, the fifth interface 505 comprises a first pin 5051 and a second pin 5052, one end of the first pin 5051 is connected with the power output end of the network transformer 101, and one end of the second pin 5052 is connected with the input end of the power module 102;

[0056] The POE module 200 further comprises a sixth interface 506, the sixth interface 506 comprises a third pin 5061 and a fourth pin 5062, one end of the third pin 5061 is connected with the input end of the POE module 200, and one end of the fourth pin 5062 is connected with the output end of the POE module 200;

[0057] In the case that the third cable 403 is inserted into the fifth interface 505 and the sixth interface 506, the first sub-cable 4031 is connected to the other end of the first pin 5051 and the other end of the third pin 5061 respectively, and the second sub-cable 4032 is connected to the other end of the second pin 5052 and the other end of the fourth pin 5062 respectively; or, referring to Fig. 3(b), the second sub-cable 4032 is connected to the other end of the first pin 5051 and the other end of the third pin 5061 respectively, and the first sub-cable 4031 is connected to the other end of the second pin 5052 and the other end of the fourth pin 5062 respectively.

[0058] For the convenience of showing the connection relationship, the sixth interface 506 is arranged outside the POE module 200 in Figs. 3(a) and 3(b), and actually, the sixth interface 506 is an integrated interface inside the POE module 200.

[0059] The first sub-cable 4031 and the second sub-cable 4032 are insulated from each other, and the outer edge surface of the first sub-cable 4031 can be encapsulated with a first insulation layer, and the outer edge surface of the second sub-cable 4032 can be encapsulated with a second insulation layer, and the outer surfaces of the first insulation layer and the second insulation layer are encapsulated with a protective layer, thereby forming the third cable 403. In actuality, the first sub-cable 4031 and the second sub-cable 4032 can be cables of the same model, and both can support the power of POE power supply, so that when connected, the first sub-cable 4031 and the second sub-cable 4032 do not need to be distinguished, and only one of them needs to be connected to the first pin 5051 and the third pin 5061, and the other one needs to be connected to the second pin 5052 and the fourth pin 5062. Thus, the installation operation can be simplified. In addition, the first sub-cable 4031 and the second sub-cable 4032 are encapsulated together by the protective layer, which is convenient for carrying and makes the connection harness more tidy.

[0060] In a possible implementation, referring to Figure 4 , the image acquisition system further includes a direct-current power supply module 400.

[0061] The output end of the direct-current power supply module 400 is connected to the input end of the power module 102.

[0062] In some application scenarios of the embodiment of the utility model, when POE power supply is not needed, the industrial camera 100 does not need to be powered by the POE module 200, and therefore Figure 4 the POE module 200 in the above can not exist. When POE power supply is not needed, the direct-current power supply module 400 can be used for power supply, and the direct-current power supply module 400 directly transmits the direct-current voltage required by the industrial camera 100 to the power module 102, which can expand the use scenarios of the industrial camera 100.
