What should I pay attention to when installing a wireless bridge?

With the development of network technology, wireless bridge transmission technology has been widely used. From the small elevators to the monitoring in the residential area, to the deep forest fire prevention, and the monitoring of rivers in the sea, we can see the implementation projects of the transmission technology of the network cable bridges. So, what should you pay attention to in the installation process of the wireless bridge? The following Xiaobian lists several articles for everyone.

First, the wireless bridge equipment installation and fixed.

When installing the wireless bridge, the first is the fixing of the wireless bridge equipment support. The stability of the support directly affects the stability of the signal transmission. During the installation, because the surface of the bracket is relatively smooth, it is necessary for the installation to be closely contacted with the U-shaped clamping code by putting a rubber band on the bracket. In order to prevent prolonged exposure to outdoor rainwater, the contact between the U-shaped clip and the bracket is loosened when the surface of the bracket is rusted. In addition, the antenna of the transmitter and receiver of the wireless bridge must be aligned to ensure a stable reception signal.

Second, equipment hardware installation

Wireless bridge devices are generally powered by POE. Therefore, POE power supply boxes, wireless bridges, and surveillance cameras must be properly connected during the installation process to ensure normal signal reception in the hardware of the entire system.

Third, equipment network cable and length control

Although the wireless bridge device is a wireless transmission signal, the device and the control center as well as the transmitter and the camera and the power supply box still need to be connected by a network cable. The network cable connecting the wireless bridge and the power supply box (POE) should not be too long. The network cable requires two types of cable selections, CAT5e or CAT6. The length of the network cable should not exceed 25m to avoid insufficient power supply. The network cables of POE and network cameras, switches, NVRs and other devices should not exceed 100m to avoid network signal attenuation. When the POE data transmission port is far away from the monitoring center or equipment room (over 100m), it is recommended to use optical fiber transmission.

Fourth, POE power supply box, wireless bridge, network cameras or switches and other network equipment, the correct connection.

POE power supply box generally has three interfaces: power interface (usually DC DC input), POE network port (only used to connect the RJ45 port of the wireless bridge device), network port or LAN port (can be connected to any Ethernet based Network equipment, such as: network cameras, switches, routers, computers, NVRs, etc.). When connecting these three interfaces, you must pay attention to their correctness.

Five, POE power box model selection

There are two POEs that are currently recommended for use. The modular POE for external DC power input and the internal integrated transformer use a stabilized POE with an AC 220V voltage input. It should be noted that regardless of which type of POE is used, the interface definition is uniform. The network port labeled "DATA IN" on the POE can be connected to network cameras, switches, computers and other network equipment, and marked with "P + DATA OUT". The network port can only connect to the wireless bridge device. If it is wrong, it will cause the device to burn out. Therefore, be careful.

Fifth, the equipment is rainproof, dustproof and insulated.

Because the wireless bridge equipment is generally installed outdoors, in the case of severe weather, it is necessary to protect the equipment against rain, dust, and insulation in order to ensure the safe and stable operation of the entire equipment. First of all, the connection parts of the network bridges of wireless bridges, POEs, and network cameras need to be well protected from rain and dust, and the joints of wireless bridges and network cables generally need to be wrapped with 2-3 layers of waterproof tape. Try not to expose the crystal heads; network cables and networks. The camera connection part also needs to be wrapped with two or three layers of waterproof tape or insulating tape; all power connector parts should be insulated as much as possible. To prevent seepage.

Six, equipment, lightning protection

Because the equipment is installed outdoors, and the equipment is usually in a relatively high position in order to avoid obstacles, lightning protection measures must be provided for the equipment. The correct method of lightning protection and grounding is: the pole of the fixed wireless bridge. Install the lightning rod, the grounding terminal of the wireless bridge needs to use a copper core wire (usually 4mm2) and the lightning protection line to connect to the ground.

VII. Software debugging of equipment

1. The wireless bridge device debugging needs to enter the software debugging interface of the device through IE browser or a third-party browser. The specific method is to first change the IP address of the local computer to ensure that the IP address of the device and the IP address of the local computer are in the same network segment; the operation method is as follows: Open the "Control Panel" â†’ "Network and Sharing Center" â†’ "Change the adapter settings â†’ "Local Area Connection" â†’ "Properties" â†’ "Internet Protocol Version 4 (TCP/IPv4)" Manually set the computer's IP address.

2, correctly plan the wireless bridge IP address

The wireless bridge device itself has a built-in correctly planned IP address of the wireless bridge. Wireless transmission systems using wireless bridges will use a large number of IP addresses. In order to prevent the IP address of wireless bridge devices from conflicting with IP addresses of other devices on the LAN, we usually use two methods. First, divide the independent network. Separate the wireless transmission network formed by wireless bridges from other networks (such as office networks and server networks) and use a single core switch. Second, re-plan the IP addresses of devices. Divide the IP address of the wireless bridge device and the network camera and hard disk recorder IP address in different network segments.

The above are the precautions needed to install a wireless bridge device. It can be seen from the above knowledge that the installation of a wireless bridge requires not only good quality equipment but also excellent technical personnel. More wireless bridge knowledge information, you can pay attention to the latest technology development of Tengyuan Zhituo.

Seed Cleaner & Grader

Machine Introduction:

The primary method of seed cleaning is the Air Screen Cleaner.Seed Cleaner and Grader uses a combination of air and screens to separate seed based on size, shape, and density. These widely-use units come in a variety of models with two to eight vibrating screens. In all cases, the cleaning principles are the same. The grains are fed into the hopper where they are evenly distributed by a feed roller and transferred through a controlled gate on the top sieve. In the process the grains are subjected to primary aspiration by the use of air trunk which drains off chaff, straw, dust or deceased grains. Then the material is passed through sieve layer for separation according to their width and thickness. After the separation, the graded material is subjected to air sifter and aspiration chamber where remaining light particles are sucked off by a strong upward draught of air. The graded material and the impurities are automatically discharged in separate chutes.

These machines are suitable for efficient cleaning of all types of grains and seed. Gentle feeder and the belt guard provide efficient cleaning of grain without causing any damage to the particles. High in functionality, The shoes of the machine can easily be replaced for different type of cleaning. Our range of 5XZC series Seed Cleaner Cum Grader is specially designed for heavy-duty operation at the most economical prices.

Operation:
Seeds/Grains are fed into a feed hopper where they are evenly distributed by a feed roller and drop through a controlled gate on the air sifter and aspiration where light particles are sucked off by a strong upward draught of air top sieve. Before falling on Top Screen, grains are subjected to primary aspiration which drains off chaff, straw, dust, deceased grains etc. Material is then passed through two sieve layer for separation according to width and thickness. Sieve perforations are kept cleaned by specially designed rubber balls.After passing through screens, cleaned/graded material again passes through. Final product and impurities are collected separately through discharge chutes.
