Description
Technical Field
The utility model relates to a internet of things, office automation and security protection field especially relate to a network relay.
Background
A relay is an electronic control device having a control system (also called an input loop) and a controlled system (also called an output loop), which is generally applied to an automatic control circuit, and is actually an "automatic switch" that uses a small current to control a large current; therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. The existing relay is a product decades ago, the innovation direction of the existing relay is continued to the protection of overvoltage, overcurrent and low voltage, and the intelligent control direction is still in the future, so that the existing relay is behind the current internet era and the mobile internet era; therefore, a network relay is very necessary to design.
SUMMERY OF THE UTILITY MODEL
This utility model aims to provide a relay for solve prior art relay and do not possess the network function, unable remote intelligent control's problem.
The relay can be connected with a network in a wired mode, can receive a switching instruction from the network, can report the switching state of the relay through the network, can be used for switching on and off all connected electric products in a timing mode, and can realize remote control and state monitoring of the electric products.
The utility model provides a network relay, include: upper casing 1, leaded light transparent LOGO 2, control circuit board 3, lower casing 4, wherein, control circuit board 3 contains CPU301, power supply circuit 302, ethernet controller 303, RJ45 network interface 304, pilot lamp control circuit 305, pilot lamp 306, relay control circuit 307, relay 308, connecting terminal 309.
The relay connect on relay control circuit, the utility model discloses a have a plurality of relays, relay control circuit connects on the CPU interface.
The pilot lamp connect on pilot lamp control circuit, the utility model discloses only have the pilot lamp of two different colours, pilot lamp control circuit connects on the CPU interface.
The indicator lights and the relays are in a one-to-many mode, and the on-off states of the corresponding relays are judged according to the colors and the flashing times of the two lights.
The RJ45 network interface is connected to an Ethernet controller and used for plugging a network cable.
The connecting terminal is connected with external products such as a card reader, a door-out button switch, a fire alarm and the like.
As described above, the utility model discloses a network relay has following advantage:
the relay is connected with a network in a wired mode, can receive a switching instruction from the network, can report the switching state of the relay through the network, can switch all the connected electric products in a timing mode, and can realize the remote control and state monitoring of the electric products.

Detailed Description
As shown in fig. 1, the utility model relates to a box body, the main component part has epitheca 1, the transparent LOGO 2 of leaded light, control circuit board 3, inferior valve 4. The core of the box is a control circuit board in the box. As shown in fig. 2, the control circuit board 3 includes a CPU301, a power supply circuit 302, an ethernet controller 303, an RJ45 network interface 304, an indicator lamp control circuit 305, an indicator lamp 306, a relay control circuit 307, a relay 308, and a connection terminal 309.
In actual operation, the power circuit 302 has a voltage transformation function, and can convert 220V or 110V mains power into 12V for the control circuit.
Pilot lamp 306 link to each other with pilot lamp control circuit 305, the utility model discloses only two lamps of different colours, the colour and the scintillation number of times through two lamps judge the on-off state that corresponds the relay, light is derived through the transparent LOGO of leaded light and is shown on the casing.
The RJ45 network interface 304 is connected to the ethernet controller 303 for plugging in a network cable.
The relay 308 be connected with relay control circuit 307, this utility model has a plurality of relays, and relay control circuit 307 is connected with CPU 301.
Upper casing 1 and the transparent LOGO 2 of leaded light adopt the screw stationary phase to be connected to conveniently derive pilot lamp 306 light signal. The control circuit board 3 and the lower shell 4 are connected and fixed by adopting self-tapping screws, and then the self-tapping screws are locked after the upper shell 1 and the lower shell 4 are assembled and clamped together, so that the complete network relay product is assembled.
This uses novel for the box body product in the actual work, and control circuit is inside the box body, and relay interface, RJ45 network interface, power source and other interfaces all expose outside the box body, make things convenient for the plug to connect, and the box body has fixed knot structure to make things convenient for fixed network relay in addition.
The utility model discloses need to set up the IP address in the actual application.
As described above, the utility model discloses network relay has following beneficial effect:
the utility model discloses a wired connection makes the relay have the network function, can in time and the terminal between the information interaction, but each relay on-off state of remote monitoring and control.
