Problems solved by technology

[0014] The technical problem to be solved by the present invention is to provide a kind of 2.4GHz wireless communication device, it can only need to install a wireless modem to act as a base station, avoid using multiple base stations to cause the blind area between multiple signal coverage areas; solve the existing 2.4 at the same time GHz wireless network signal transmission distance is short, the signal coverage is small, and the application effect is poor in complex environments.

Embodiment 1

[0027] like figure 1 As shown, the main body of the factory area is a track with a total length of 1070 meters. There are many vegetation in the middle of the track, and part of the track is inside the factory building and part is outside the factory building. The transportation equipment running on the track needs to transmit the status data to the master controller wirelessly, and remotely receive the control instructions from the master controller. The use of wireless communication in this harsh environment will greatly weaken the strength of the wireless signal, and the straight line length of the track reaches about 500m, which puts forward high requirements on the stability of the wireless signal in the whole factory.

[0028] in such as figure 1 In the complex environment shown, it is not possible to simply use an omnidirectional antenna or a unidirectional antenna. A combination of directional and omnidirectional antennas is required. Under the premise of fully cons...

Embodiment 2

[0070] like figure 2 As shown, its environment is similar to figure 1 , but according to the actual situation, the length of the factory building on the left is 500 meters, so a set of high-gain directional antenna 1 can be used to transmit the signal to cover this area. , a set of omnidirectional antenna 3 can be installed in the center of the factory building on the right to achieve full coverage, and the base station can be installed near the directional antenna 1 to reduce signal loss.

Embodiment 3

[0072] like image 3 In the situation shown, there is a partition 4 in the middle of the factory building on the right, which will affect the coverage of wireless signals. Two sets of omnidirectional antennas 3 can be installed so that the signals emitted by the two sets of omnidirectional antennas 3 can cover different areas and achieve full coverage. At the same time, it is necessary to adjust the installation position of the base station and the gain of the antenna according to the situation.

[0073] In Embodiment 2 and Embodiment 3, the connection mode between the modem, the lightning arrester, and the power divider, and the connection mode between the power divider and the antenna are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a 2.4GHz wireless communication device, in particular a device using 2.4 GHz wireless communication in a complex industrial environment. The 2.4GHz wireless communication device comprises a direct sequence frequency-hopping modem, wherein the modem is connected with at least two power distributors, at least one power distributor is connected with at least one set of directive antenna, and at least one power distributor is connected with at least one set of omni-directional antenna. Due to the technical scheme of the invention, the technology of 2.4GHz wireless communication can be used in a complex environment. The 2.4GHz wireless communication device only needs to be provided with one wireless modem as a base station to avoid blind areas among a plurality of signal-covered areas caused by using a plurality of base stations. The invention also has the advantages of remote signal transmitting distance, wide signal-covered range and good applying effect in a complex environment.

Description

technical field [0001] The invention relates to a wireless communication device, in particular to a device for applying 2.4GHz wireless communication in complex industrial environments. Background technique [0002] Industrial wireless technology has advantages that wired technology cannot or is difficult to replace in many applications. From saving connection wires to improving operation, it can effectively improve the efficiency of users in asset management, equipment diagnosis, supervision and control and other fields. However, due to the particularity of the wireless signal, its communication distance is inversely proportional to the data transmission, and the strength and coverage of the wireless signal are affected by the site conditions and weather, so the effect of applying wireless communication technology in complex environments is not ideal . [0003] The wireless communication methods using the frequency band near 2.4GHz are collectively referred to as 2.4GHz te...
