Embodiment
The utility model is by the simple modifications to NVR, and coordinates Multi-netmouth connector, thereby realize a NVR, can carry a plurality of web cameras and without the access of switch, effectively reduce holistic cost.
Improvement please refer to the drawing 2 to NVR, this NVR comprises two Phy(physical layers) chip: P1 and P2.4 pins 1,2,3,6 of one of them P1 chip are connected with 1,2,3,6 pins of this NVR Ethernet interface (as the NVR side RJ45 interface in figure) respectively, and 4 pins 1,2,3,6 of P2 chip are connected with 4,5,7,8 pins of this NVR Ethernet interface respectively.Whole NVR improvement physically has only increased a Phy chip.
In order to realize a NVR, can directly connect a plurality of IPC, need to make improvements connecting the connector of NVR and IPC.Please refer to the drawing 3, Fig. 3 is the exemplary plot in kind of a kind of Multi-netmouth connector after improving.This Multi-netmouth connector comprises 5 connectors and cable, and wherein 1 connector (NVR side-connector) inserts the Ethernet interface of NVR, and other 4 connectors (IPC side-connector) insert respectively the Ethernet interface of different IP C.
Cable annexation please refer to the drawing 4 between 5 connectors.1,2,3,6 pins of the RJ45 connector of NVR side are connected with 1,2,3,6 pins of the 2nd RJ45 connector (A2) with 1,2,3,6 pins of a RJ45 connector (A1) of IPC side respectively by twisted-pair feeder.4,5,7,8 pins of the RJ45 connector of NVR side are connected with 1,2,3,6 pins of the 4th RJ45 connector (B2) with 1,2,3,6 pins of the 3rd RJ45 connector (B1) of IPC side respectively by twisted-pair feeder.
By above-mentioned Multi-netmouth connector, 4 IPC have directly accessed NVR equipment, have reduced on the whole the networking cost of this miniature video monitor network.
After being connected by Multi-netmouth connector of the present utility model with NVR at IPC, also need the mode of operation of NVR and IPC to arrange.The IPC1(that NVR, a RJ45 connector (A1) connect is not shown), the speed of the IPC2 that connects of the 2nd RJ45 connector (A2) is all set to 10M, dual-mode is all set to full duplex; The MDI pattern of NVR can be set to general mode, also can be set to cross-mode.This is relevant with the MDI pattern that IPC2 arranges with IPC1, if IPC1 and IPC2 are set to cross-mode, NVR is set to general mode; If IPC1 and IPC2 are set to general mode, NVR is set to cross-mode.The Ethernet message that now NVR sends, IPC1, IPC2 can receive simultaneously, and the message NVR that IPC1 sends can receive, and IPC2 cannot receive.Under above-mentioned configuration, NVR can communicate by letter respectively at IPC1, IPC2 to be less than the speed of 5M, and cannot proper communication between IPC1, IPC2.In typical case's application of economical NVR, bandwidth is generally less than 2M, and between IPC1, IPC2, does not need communication.So this scheme of the present invention's design meets actual application demand.Arranging of the IPC4 mode of operation that the IPC3 that NVR, the 3rd RJ45 connector (B1) connect is connected with the 4th RJ45 connector (B2) is the same.When NVR communicates by letter with IPC1 or IPC2, can not form interference to IPC3, IPC4; When similarly, NVR and IPC3 or IPC4 communicate, can not form interference to IPC1, IPC2 yet.
By such scheme, realize a NVR and directly connected four IPC, one drag four cheap scheme, meet the application of small-sized solution.
More than to take Multi-netmouth connector that a RJ45 connector drags four RJ45 connectors to describe as example.If only need a RJ45 connector to drag two RJ45 connectors to satisfy the demands in the middle of practical application, can design according to Fig. 5 (a) and Fig. 5 (b).The Multi-netmouth connector of one drag two comprises a RJ45 connector that connects NVR, connects the 2nd RJ45 connector of IPC and the 3rd RJ45 connector that connects another IPC; 1,2,3,6 pins of the one RJ45 connector are by 1,2,3,6 pins of twisted pair line connection to the two RJ45 connectors, and 4,5,7,8 pins of a RJ45 connector are by 1,2,3,6 pins of twisted pair line connection to the three RJ45 connectors.By a RJ45 connector being inserted to the network interface of NVR, the 2nd RJ45 connector is inserted to the network interface of IPC, the 3rd RJ45 connector is inserted to the network interface of another IPC, realized two IPC not by the object of switchboard direct access NVR.In this manner, the mode of operation of NVR is set to: 10M/ full duplex, and MDI pattern can be set to general mode or cross-mode; The mode of operation of IPC is set to: 10M/ full duplex, MDI pattern is set to cross-mode or general mode.About MDI pattern, NVR is always relative with IPC, and one while being cross-mode, another is general mode.
More than provided two examples embodiments of the present invention have been described.In fact the design based on same can also have a RJ45 connector to drag the Multi-netmouth connector of three RJ45 connectors, five RJ45 connectors, six RJ45 connectors etc.In practical application, can make according to demand.
More than to take this Multi-netmouth connector to be applied to NVR and IPC and to describe as example, in fact on some other electronic equipment, also can use, such as network intelligence electrical equipment (switch, water heater, air-conditioning) need to connect a plurality of equipment, and the occasion smaller to network bandwidth requirement.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
