Description

Technical Field

[0001] The invention relates to the field of medium wave transmitter control, in particular to a medium wave intelligent broadcast control system. Background Art

[0002] The number and types of transmitters of news broadcasting and television stations are large, and the protocols are different. They do not support all transmitter applicable systems. The original signals received by the satellite have not been processed, and the source sizes of each program are different, resulting in uneven broadcast effects. When the sound source is too large, the transmitter is overloaded, and sometimes the transmitter is damaged, resulting in sound leakage, which cannot meet the requirements of real-time broadcasting. Moreover, when the transmitter fails to alarm, the fault parameters cannot be saved in time, resulting in missing when querying the operating status, and the working status of the 24-hour transmitter is not recorded. This is a very serious problem. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a method for realizing the intelligent monitoring and control system of a medium wave transmitter, including a medium wave transmitter management system, a front-end information source monitoring system, and an external equipment monitoring system. Among them, the medium wave transmitter management system includes: a server, an operation terminal, a data acquisition controller, a fault switching industrial computer, a GPS / BD dual-mode timer, a temperature and humidity acquisition system and ancillary facilities. The transmitter and the data collector use serial communication to exchange data, and the server and the data collector and the operation terminal use a network cable to exchange data. The front-end information source monitoring system includes: a computer spectrum analysis oscilloscope, an audio processor, an audio switcher, a broadcast receiving processor and ancillary facilities. The sound source enters the satellite receiver and is automatically processed by the audio processor, and then automatically switched by the audio switcher, and the effect is heard from the broadcast receiving processor. It supports simultaneous monitoring inside and outside the front-end information source link, supports visual monitoring of the broadcast amplitude of the medium wave program, and also supports cyclic monitoring of the broadcast effect from the auditory perspective, and operates the visual interface of each device.

[0004] The medium wave intelligent broadcast control system provided by the present invention is divided into 11 major modules for management, namely medium wave transmitter management, medium wave program broadcasting, medium wave audio processing, medium wave audio switching, medium wave audio reception, medium wave loop monitoring, equipment management, general management, system management, log management, and report system. The overall functional structure of the system is shown in the attached figure. Figure 3 The medium wave intelligent broadcast control system includes the following aspects:

[0005] 1. Medium wave transmitter management is the management of medium wave transmitters, including the name, manufacturer, model, equipment alarm parameter settings, etc. of the transmitter, real-time monitoring of the dashboard, including frequency scanning and stopping, alarm release and transmitter data display (transmitting frequency, forward power, reverse power, amplifier voltage, amplifier current, alarm information, temperature and humidity, etc.).

[0006] 2. Medium wave program broadcasting is divided into program settings, planned programs, real-time programs, etc. The program broadcasting frequency is preset in advance, and the planned program is generated after submission. After approval by a person with higher authority, the preset program is actually broadcast.

[0007] 3. Medium wave audio processing mainly monitors and processes the sound source transmitted by the satellite receiver automatically. If the monitored sound source is too loud, it will be suppressed; if the sound source is too small, it will be amplified. It can also run normally after power failure. The system can also monitor the effect of the sound source broadcast.

[0008] 4. The medium wave audio switch mainly monitors the input of the audio source automatically. If there is a problem with the audio source in a certain link, it will automatically switch to other interfaces for normal operation. The system can also monitor the running channels.

[0009] 5. Medium wave audio reception mainly listens back to the sound source broadcast by the transmitter and monitors the broadcast effect from outside the link.

[0010] 6. Medium wave loop monitoring mainly uses automatic and manual methods to receive the sound source of medium wave audio. The system can freely choose to perform some kind of loop monitoring.

[0011] 7. Equipment management is divided into transmitter management, temperature and humidity equipment management, topology configuration and antenna management, etc. Manage the basic information of transmitters, temperature and humidity and antennas, including the name, manufacturer, model, equipment alarm parameter settings and start-up of backup transmitters, temperature and humidity and antenna location management, antenna and transmitter matching and other functions.

[0012] 8. System management manages system-level functions, including user management, role management, authority management, review process management, etc. Configuration of transmitter parameter information, setting of operator authority, setting of alarm threshold, etc.

[0013] 9. Log management mainly manages the operation logs of the system and the equipment, including system logs and alarm logs. With logs, you can query previous operations, track problems after they occur, and make statistics on personnel operations.

[0014] 10. Statistical reports mainly count data related to the equipment, and are displayed more intuitively in the form of graphic reports, including the query and statistics of the total transmission time trend chart and the frequency transmission time report.

[0015] The convenience and benefits brought by the present invention are that it is compatible with various types of transmitters currently in use, realizes automatic processing, and has a friendly human-computer interaction interface at the operation terminal, clear authority settings, supports multiple operating systems, has strong system stability and anti-interference, high security and maintainability, stable data transmission, easy installation, a reserved remote control interface, adopts international general standards and realizes clock synchronization through GPS.

[0016] The innovative features of the present invention mainly include:

[0017] 4. Collection of various working states and parameters, including forward power, reverse power, amplifier voltage, amplifier current, operating temperature, operating frequency and working state, and real-time monitoring and display of main operating parameters and temperature and humidity of AC power and UPS.

[0018] 5. Report statistics, including the query and statistics of annual and monthly reports such as frequency transmission duration, reduce the workload of statisticians.

[0019] 6. Fault detection and alarm location. Perform self-test and real-time alarm on faulty nodes and perform automatic safety switching operations to reduce the workload of operators, improve work efficiency, and complete the launch mission in real time and safely.

[0020] 7. Dual hot standby mechanism for main and backup servers. When an unexpected situation causes the main server to fail, the backup server is activated through the dual hot standby mechanism, and the complete data is imported to ensure that the launch mission continues to operate normally.

[0021] 8. Data acquisition controller hardware takeover mechanism. Even if the main and backup servers fail or lose power at the same time, the independent data acquisition controller equipped with each transmitter can still detect the status of the transmitter and control the transmitter to perform the original task normally, ensuring the smooth completion of the transmission task.

DETAILED DESCRIPTION

[0023] The present invention will now be further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Example 1

[0025] After completing the transmitter configuration and system parameter settings, enter the actual broadcast operation diagram, and after approval, activate the operation diagram and the corresponding transmitter to execute the transmission task. The transmitter with the task will be turned on and preheated 10 minutes before the task starts. When the task is executed, it will be tuned before transmitting, and shut down immediately after the task is completed. You can adjust the power, emergency stop, monitor the operating status of transmitters and other equipment in real time, query and record statistical results, etc. Among them, operations such as logging into the system, modifying the operation diagram, and alarm and release will be recorded in the system log and alarm log respectively for query.

[0027] Based on Example 1, this Example 2 provides another implementation method of the transmitter intelligent control system as described in Example 1.

[0028] In this embodiment 2, based on the embodiment 1, when the main server fails, the backup server is enabled through the dual-machine hot standby mechanism, and the complete data is imported to ensure that the transmission task is still executed normally, and sufficient time is reserved for repairing the main server to restore the dual-machine hot standby mechanism. If the backup server also fails at this time, the data acquisition controller will detect that the communication with the server is abnormal, and the data acquisition controller will enter the state of taking over the transmitter, and execute the transmission task according to the original schedule, ensuring the normal execution of the task, and gaining precious maintenance time for the emergency repair of the main and backup servers. When the server is repaired, the communication reconnection is successful, and the data acquisition controller can exit the state of taking over the transmitter, and the server resumes intelligent control of the data acquisition controller.
