[0002] At present, the port operation site broadcasting system is mainly used for production dispatching and directing cargo yard personnel to carry out safe production operations, and is frequently used. During use, the broadcasting line often fails (short circuit or open circuit), resulting in the inability to shout and fail to contact the on-site operators in time, affecting safe production. If a failure occurs, since the broadcasting line is erected about 1,000 meters in the air, it is difficult to troubleshoot the long-distance fault at high altitude, which takes a lot of time and affects safe production. Utility Model Content

[0003] In view of this, the utility model proposes an intelligent FM wireless broadcasting system for the work site with functions such as wireless connection, intelligent transmission, noise reduction and anti-interference. The specific scheme is as follows:

[0005] Furthermore, the FM transmitter model is FM-9036, the FM receiver is FM8100, and the smart broadcasting is a remote smart broadcasting model YH-9802.

[0006] It is further written that the microphone is connected to the FM transmitter via wired transmission.

[0007] Furthermore, the transmitting antenna adopts a double-section single-rod vertically polarized transmitting antenna.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The utility model can realize remote control on the mobile phone and computer. Turn on the power of the FM transmitter and speak directly through the microphone connected to the FM transmitter. The power of the remote intelligent broadcast YH-9802 is always on. The remote intelligent broadcast is remotely controlled by the mobile phone APP, and then the remote intelligent broadcast controls the stereo FM transmitter to realize remote control on the mobile phone. The remote intelligent broadcast is remotely controlled by the PC, and then the remote intelligent broadcast controls the FM transmitter to realize remote control on the PC. The system ensures that the production dispatcher reminds the operator to work safely, and the use effect is very good, which has been unanimously praised by the user unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] The utility model is further described below in conjunction with the accompanying drawings.

[0012] Embodiment 1: In order to make the technical means, innovative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to the accompanying drawings.

[0013] The FM broadcast transmitter in this embodiment is 1. Stereo FM broadcast transmitter FM-9036, with stereo FM transmission output, LCD 4-inch large screen display, frequency, power, address code, volume, partition, CPU temperature, standing wave ratio, detection, antenna standing wave ratio detection, CPU temperature detection, transmitter detection, independent partition, intelligent 12-zone broadcast, built-in music, two-way stereo input and one-way remote input, automatic playback, automatic MP3 playback function when powered on, microphone input, two-way voice input, volume adjustment, 4-way volume adjustment, monitoring function, with monitoring function, adjustable, power, frequency, address code, partition adjustable, external control function, 12V external control function. (External control function is used for the next step of intelligent remote control)

[0014] The FM receiver is an outdoor FM receiver FM8100, RDS encryption to prevent interference, 64-bit digital frequency synthesis technology FM-RDS encryption remote control design verification password to prevent interference when starting up at the same frequency, prevent chickens crowing in the middle of the night to prevent intrusion of black radio stations, noise reduction and fine sound, fully enclosed shell aluminum plate heat dissipation, silent design, service life, P6 level waterproof, dustproof and anti-corrosion design, 180V-240V broadband working voltage transformer service life of more than 3-5 years, frequency does not drift, infrared frequency locking frequency does not run away, reduce debugging and maintenance costs, installation accessories, comes with mounting bracket, pole and wall compatible installation is more convenient.

[0015] The horn speaker is a 50W speaker, a 50W tweeter, and a tweeter horn speaker, which has a wider propagation range and is suitable for wireless terminal receivers.
