Description

Technical Field

[0001] This invention relates to the field of production communication technology, and in particular to a wireless communication device for chemical production. Background Technology

[0002] In the field of chemical production, the signal shielding effect of the main control room building structure and explosion-proof coating, as well as the attenuation effect of tall structures such as towers and tanks in the production unit on the wireless communication signal of explosion-proof walkie-talkies, result in weak wireless communication signals and poor call quality in the main control room. Furthermore, there are local blind spots in the wireless walkie-talkie signal within a range of 340 meters, which hinders communication between on-site operators and the main control room. This seriously affects the safe production, emergency response, and various efficiency improvement research projects of the unit. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses a wireless communication device for chemical production, comprising a building structure and a lightning rod fixedly installed on the upper edge of the building structure, a walkie-talkie for communication, and a vehicle-mounted unit installed inside the building structure. An antenna is fixedly connected to the lower part of the lightning rod, and the lower end of the antenna is electrically connected to a coaxial cable. The other end of the coaxial cable is electrically connected to the vehicle-mounted unit. Using the vehicle-mounted unit as a relay device, and simultaneously mounting the antenna on the upper part of the building structure, facilitates increased signal coverage, thereby improving the communication range of the walkie-talkie.

[0004] The building is equipped with a UPS power supply, which is electrically connected to the vehicle-mounted radio. The UPS power supply ensures uninterrupted power supply to the vehicle-mounted radio and prevents communication disruptions due to power supply issues.

[0005] Preferably, a coaxial surge arrester is provided at the lower end of the antenna, and the coaxial surge arrester is connected in series with a coaxial cable. Feeder connectors are provided above and below the coaxial surge arrester. Since the antenna is fixedly connected to the lightning rod, the risk of being struck by lightning is greatly increased. Therefore, a coaxial surge arrester is provided for protection. At the same time, fixing the antenna to the lightning rod facilitates quick fixation of the antenna without causing damage to the building structure.

[0006] Preferably, the feeder connector is model N-J1 / 2. The feeder connector used is a common model, readily available on the market, which facilitates the installation of the device.

[0007] Preferably, the lower end of the antenna is provided with a U-shaped screw, which fits into the lower part of the lightning rod. The U-shaped screw is a common connector, readily available and easy to use, facilitating the installation of the device.

[0008] The beneficial effects of this invention are as follows:

[0009] 1. By adding a vehicle-mounted station and mounting the antenna on the top of the building, the signal range was greatly improved, meeting the needs of chemical production.

[0010] 2. Equipped with a coaxial surge arrester and UPS power supply, it can ensure the stable operation of the vehicle-mounted radio and facilitate stable communication.

[0011] 3. This solution is simple, the components are readily available, and it facilitates rapid installation and modification. Attached Figure Description

[0016] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0017] like Figures 1 to 2As shown, a wireless communication device for chemical production includes a building 1, which is a production building in the factory area, specifically a main control room and a comprehensive building. The total length of the building is 61.07m and the width is 12.4m. The control room is located on the west side, with axes 4 to 8. The north side of the main control room has multiple explosion-proof doors and windows (originally non-explosion-proof). A lightning rod 8 is fixedly installed on the upper edge of the building 1, serving as a protective structure. The device also includes walkie-talkies, such as the Motorola GP328D+ explosion-proof digital walkie-talkie and the Hytera PD700 explosion-proof digital walkie-talkie. A vehicle-mounted radio 3 is installed inside the building 1, serving as a relay device and for communication with the main control room; the model is Motorola XIR. The M3688 lightning rod 8 has an antenna 7 fixedly connected to its lower part. The antenna 7 is made of omnidirectional fiberglass, and its lower end is electrically connected to a coaxial cable 4, specifically a 1 / 2 coaxial cable. The other end of the coaxial cable 4 is electrically connected to the vehicle-mounted radio 3. By installing the vehicle-mounted radio 3 and antenna 7, and by mounting antenna 7 on the upper part of building 1, the signal coverage and communication range of the walkie-talkie are greatly increased. The original communication range was 0.34km, and there were blind spots within this range. After the addition, the communication range can be increased to 5.2km, which is beneficial for safe production and management.

[0018] The interior of building 1 is equipped with a UPS power supply 2, which is electrically connected to the vehicle-mounted radio 3. The use of the UPS power supply 2 ensures stable communication, prevents abnormal power outages of the vehicle-mounted radio 3, and ensures safe production.

[0019] A coaxial surge arrester 5 is installed at the lower end of the antenna 7. The use of the coaxial surge arrester 5 is to improve the stability of communication. The coaxial surge arrester 5 is connected in series with the coaxial cable 4. Feeder connectors 6 are installed above and below the coaxial surge arrester 5.

[0020] The feeder connector 6 is model N-J1 / 2. The feeder connector used is a common model, readily available on the market, which facilitates the setup of the device.

[0021] A U-shaped screw 9 is provided at the lower end of the antenna 7, and the U-shaped screw 9 is fitted into the lower part of the lightning rod 8. The U-shaped screw 9 is a common connector, which is easy to obtain and use, and facilitates the construction of the device.
