2. Overview of intelligent medium wave switchgear
The transmitter and antenna feed interlock control system is a custom-sized cabinet product (intelligent medium wave switch cabinet), placed between the primary and secondary transmitters, at the same height as the transmitter. The front panel consists of a 15-inch touch display and a switching device of the corresponding size. Among them, the touch screen integrates the display and control functions of all the functions of the transmitter, feed cable, and antenna network interlock control system. The display control interface of each function adopts modular display, and the interface is simple and generous, which can display the working link status of the antenna feeder and the main technical parameters of the transmitter during operation in real time.
The transmitter and antenna feeder interlock control system is mainly composed of a series of passive components such as control module, coaxial switch, connector, etc., which mainly realizes the remote and local switching functions of the transmitter, antenna feeder, and antenna tuning network system. It can realize the integration of the primary and secondary transmitters, the primary and secondary feeder cables, and the primary and secondary antenna modulation network by one cabinet. It can be displayed and switched between the transmitter operation observation area and the antenna interlock control cabinet, and can be configured with emergency physical control keys and mechanical power insertion and removal through touch screen one-button switching control. The primary and secondary transmitters, primary and secondary feedpipes, and primary and secondary networks can be switched either electrically or manually. Transmitter and antenna interlock control system access station and intelligent operation and maintenance supervision platform of medium wave station management center.

3.the main functions of intelligent medium wave switchgear
Transmitter and antenna feed interlock control system is the core equipment of antenna feed system automation platform, the main functions are:
Function of primary and standby network switching system;
Main and standby transmitter switching system function;
Transmitter interlocking function;
coaxial switch manual control function;
Synchronous control function when the main and standby of the feed cable are switched;
Contact and control function of electric control tool brake;

4. the transmitter and antenna interlock control system switch
(1) The medium wave antenna feeder interlock switching system can complete the function of master/backup transmitter switching, master/backup feeder switching, and master/backup network switching, and also has the function of interlocking with the transmitter, antenna network and false load.
(2) The switchgear switching device is composed of a coaxial switch, hard feed, elbow, jumper and related connecting devices. After the main and standby transmitters of each frequency medium wave transmission system pass through the switch cabinet, the main output is connected with coaxial hard feed and coaxial cable (soft feed), and the coaxial cable (soft feed) is connected to the antenna allocation room along the indoor cable bridge and outdoor cable rack. One output is connected to the dummy load using coaxial hard feed.
(3) The hard feed connection port of the switch cabinet switching system with the transmitter and fake load is above the cabinet, and the connection port with the main feeder is formulated according to the site.
(4) The power capacity and other technical indicators of the antenna feeder switching system meet the requirements of the normal operation of each frequency transmitter.
(5) Antenna feeder switching system with manual crossover function. When there is a problem with the coaxial switch and circuit system, it can be quickly disassembled and manually switched by U-Link. The quick connection between transmitter and feeder and dummy load is realized by manual crossover mode, and the coaxial switch is overhauled without stopping broadcasting. The manual crossover function is designed to facilitate the independent operation of the on-duty personnel.
(6) The coaxial switch of this system has manual, electric and automatic switching functions. The automatic and electric switching failure does not affect the manual switching function, and the signal transmission of the control system has anti-interference performance.
(7) Each frequency is equipped with the status indication and operation panel of the whole link of the antenna feeder switching system, which is installed in the control cabinet of the switching device and is used for the operation and status indication of the related equipment in the whole link of the antenna feeder switching system, including the RF signal flow chart of the transmitter, dummy load, switching cabinet (coaxial switch), feed cable, antenna network, transmitter tower, etc. Convenient for the duty personnel to see the signal link is on and off, the display screen is controlled by touch screen, and the touch device is installed near the switch cabinet and the transmitter to facilitate the intuitive and quick operation of the station.
(8) The system has corresponding safety measures (such as interlocking, lighting, voice, text warning and other measures) to ensure that the transmitter, coaxial switch, feed cable, sky network does not carry load switching, and forms an interlocking logic relationship with the false load and transmitter, and has an interlocking emergency blocking device.
(9) Main/standby feeder switching mode:
The antenna feeder switching system is composed of multiple coaxial switches. For the switching system, the primary and standby transmitters have two inputs, and the primary and standby feeders and the dummy load have three outputs. Through the arrangement and combination of coaxial switches, the primary and standby transmitters can complete arbitrary switching of the primary and standby feeders and the dummy load, and at the same time, all two network switching switches are configured at the antenna end. Through the antenna feeder switching system in the equipment room and the network switching switch in the allocation room, the primary and secondary transmitters, the primary and secondary feeders and the primary and secondary networks can be switched arbitrarily.

5. Transmitter switching system
Control and management of the primary and standby transmitters, including real-time monitoring of the operating parameters and other information of the transmitters. The key parameter information is displayed graphically on the software interface, including the operating parameters of the transmitters, operating frequency, transmitting power and other important parameters, and real-time monitoring of the switching status of the transmitters.
Since the intelligent operation and maintenance system of the transmitter has occupied the transmitter interface, the transmitter switching system reads and issues control commands from the acquisition and control device of the intelligent operation and maintenance system through the IP interface to realize manual and automatic switching of the primary and standby transmitters. Real-time monitoring of transmitter status and switching quantity.
