[0046] See also Figure 1 , an embodiment of the present invention provides a fault monitoring system for a transmitter, comprising:

[0047] Lower computer 10;

[0048] The lower computer 10 includes a signal acquisition module 11, a PLC module 12 and a transmitter control module 13;

[0049] The signal acquisition module 11 is electrically connected to the input end of the transmitter and the PLC module 12; the output end of the PLC module 12 is electrically connected to the input end of the transmitter control module 13; the output end of the transmitter control module 13 is electrically connected to the transmitter;

[0050] The signal acquisition module 11 is used to collect the operating parameter signal of the transmitter in real time and send the operating parameter signal to the PLC module 12; the operating parameter signal includes an analog operating parameter signal and a digital operating parameter signal;

[0051] The PLC module 12 is used to generate a fault instruction according to the operating parameter signal; and in response to the control instruction, generate a digital output value according to the control instruction, and send the digital output value to the transmitter control module 13;

[0052] The transmitter control module 13 is used to send the digital output value to the corresponding interface of the transmitter to control the operation of the transmitter.

[0053] It should be noted that the signal acquisition module is installed on the transmitter and is used to collect the operating parameter signals of the transmitter in real time. There are generally multiple transmitters in a transmitting station, so there are several corresponding signal acquisition modules. However, since each signal acquisition module will upload the serial number, model and other information of the transmitter it monitors at the same time when performing signal acquisition, there is no need to equip each signal acquisition module with an independent PLC module.

[0054] It should also be noted that the PLC module processes the collected field data through a programmable storage unit, which has high stability, reliability and adaptability. The PLC module is installed on the duty console with relatively small electromagnetic interference to achieve centralized control and decentralized management.

[0055] In an embodiment of the present invention, the fault monitoring system for the transmitter has several signal acquisition modules and a PLC module. This PLC module can process the operating parameter signals collected by the several signal acquisition modules. Similarly, the PLC module can also determine the transmitter it needs to control based on the information in the control instruction, and send the transmitter information to the transmitter control module.

[0056] In the above scheme, by collecting and monitoring the operating parameter signals of the transmitter, a fault signal can be generated in real time so as to promptly alert the on-duty personnel, effectively eliminating the problem that the transmitter equipment crashes and causes communication interruptions and the on-duty personnel cannot discover it in time; it can also respond to control instructions in a timely manner, implement various action instructions, logically control the working status of the transmitter, and eliminate transmitter faults in a timely manner.

[0057] Preferably, the signal acquisition module comprises an analog quantity transmitter unit, and the analog quantity transmitter unit is used to convert the analog signal output by the transmitter into a standard signal as an analog quantity operation parameter signal.

[0058] Exemplarily, in the embodiment of the present invention, the analog signal output by the transmitter is converted into a standard signal of 5-20 mA by the analog transmitter unit as the analog operation signal.

[0059] It can be understood that collecting analog operating parameter signals through the analog transmitter unit can achieve the function of circuit protection, and the signal transmission has high stability.

[0060] As a preferred implementation, the analog operating parameter signal includes an output power signal, a forward voltage signal and a reverse voltage signal.

[0061] For example, in the JRC transmitter, the operating parameter signal is extracted from the CFR-87-714 noise filter board. For the analog operating parameter signal, the 14, 17 and 18 terminals of the J111 terminal block of the noise filter board are connected respectively, and then the transmitter output power, the forward voltage signal and the reverse voltage signal for calculating the transmission standing wave ratio are obtained through the analog transmitter unit.

[0062] Preferably, the signal acquisition module further comprises a level conversion unit, and the level conversion unit is used to convert the signal output by the transmitter into a standard digital signal as a digital quantity operation parameter signal.

[0063] It should be noted that the standards of the digital signals output by different interfaces of the transmitter may be different. Therefore, in order to perform unified standardization processing on the digital signals, the value of the digital quantity operation parameter signal may be 1 or 0 through the level conversion unit. As an example, it is considered that the power supply voltage signal directly collected is greater than 5.2V, which is a power supply overvoltage. The power supply voltage signal is processed by the level conversion unit. When it is greater than 5.2V, the value of the corresponding digital quantity operation parameter signal is 1, which is used to indicate the power supply overvoltage, otherwise it is 0.

[0064] In a preferred embodiment of the present invention, the input end of the PLC module is connected to the analog transmitter unit and the level conversion unit through an optical fiber to achieve electrical connection with the signal acquisition module.

[0065] In another preferred embodiment of the present invention, the input end of the PLC module is connected to the analog transmitter unit and the level conversion unit via Modbus communication or EtherCAT bus to achieve electrical connection with the signal acquisition module.

[0066] As a preferred implementation, the digital operation parameter signal includes a power amplifier operation signal, a power supply overvoltage signal, a power supply overcurrent signal, a power supply fuse signal, a power supply switch signal and a power amplifier alarm signal.

[0067] As an example, in the JRC transmitter, the operating parameter signal is extracted from the CFR-87-714 noise filter board. For the digital operating parameter signal, the wires are respectively connected from the 12, 13, 14 and 15 points of the J113 terminal row of the noise filter board and the 10 and 12 points of the J112 terminal row, and then through the level conversion unit, the power amplifier operation signal, power supply overvoltage signal, power supply overcurrent signal, power supply fuse signal, power supply switch signal and power amplifier alarm signal are obtained.

[0068] Preferably, the generation of the fault instruction includes:

[0069] Comparing the collected operating parameter signals with their preset threshold ranges one by one;

[0070] When the operating parameter signal is outside the threshold range, an abnormal operating parameter signal is obtained;

[0071] A fault instruction is generated according to the abnormal operation parameter signal; the fault instruction includes a parameter name, an abnormal value and an alarm signal of the abnormal operation parameter signal.

[0072] In a preferred embodiment, for the forward voltage signal and the reverse voltage signal, instead of setting the threshold range separately for each of them, the standing wave ratio of the transmitter is first calculated based on the forward voltage signal and the reverse voltage signal, and then the calculated standing wave ratio is compared with the preset threshold range; when the standing wave ratio is outside the threshold range, a fault instruction is generated.

[0073] More preferably, the transmitter control module 13 includes a relay unit, and the digital output value is sent to the transmitter through the relay to perform logic control on the transmitter.

[0074] In the embodiment of the present invention, the relay unit is a 24V intermediate relay, which can send relevant control signals for controlling the transmitter, such as power on / off signals, to the corresponding interface board in the transmitter exciter to realize logical operation control of the transmitter.

[0075] For further information, see Figure 2 As a preferred implementation, the fault monitoring system for a transmitter further includes:

[0076] Host computer 20;

[0077] The host computer 20 is in communication connection with the slave computer 10; the host computer 20 includes a database module 21 and a human-computer interaction module 22 in communication connection;

[0078] The database module 21 is used to store the operating parameter signal obtained from the lower computer 10, and in response to the fault instruction, send the fault instruction and the operating parameter signal at the corresponding time to the human-computer interaction module 22;

[0079] The human-computer interaction module 22 is used to automatically generate a first control instruction when a fault instruction is received; if a second control instruction input by the user is received within a preset time threshold, a control instruction is generated according to the first control instruction and the second control instruction, otherwise the first control instruction is used as the control instruction; the first control instruction is to control the transmitter to stop working by controlling the power switch signal of the transmitter.

[0080] It should be noted that the upper computer can be connected to the lower computer through the Internet of Things network. In the embodiment of the present invention, the Xinjie A-BOX series products are selected, which have simple network configuration, do not require professional technology, are convenient and easy to use, support 4G full network access, GPS global positioning, serial port transparent transmission function, Ethernet VPN and other technologies, and meet the needs of the JRC transmitter fault status monitoring system based on the Internet of Things.

[0081] It should also be noted that when a fault instruction is received, it indicates that a fault has occurred in the transmitter, and a first control instruction will be pre-generated at this time to control the corresponding transmitter to shut down. If a second control instruction input by the user is received within a preset time threshold, the priority of the second control instruction is higher than the first control instruction, that is, if the second control instruction includes the current control of turning on the transmitter, the control instruction for turning on the transmitter will overwrite the control instruction for turning off the transmitter. It can be understood that if the second control instruction is to control the transmitter to turn on after 2 seconds, the final control instruction is to control the transmitter to shut down first, and execute other instructions in the second control instruction at the same time, and then control the transmitter to turn on after 2 seconds.

[0082] For example, the upper computer realizes Ethernet communication connection with the lower computer through the RJ45 Ethernet interface, which can achieve faster and more stable program / data downloading with better real-time performance; at the same time, it supports the lower computer, especially the PLC module to access the Internet to realize remote search, online monitoring, uploading and downloading, etc., and can directly establish connection with various variables of the upper computer human-machine monitoring interface, which is convenient to operate.

[0083] In the embodiment of the present invention, the main functions of the human-computer interaction module include status monitoring, fault alarm, and control operation. By establishing a human-computer interface through configuration software such as Touch Win Pro, Kingview, and MCGS, the duty personnel can intuitively monitor the operating status of each transmitter; by setting up the OPC service, the upper human-computer interface and the lower computer are connected to establish a data connection, and the duty personnel can set and control each transmitter; through the database module, the operating status of each transmitter, such as frequency, power, standing wave ratio, and other parameters can be automatically recorded and a record table can be created, and fault alarms can be recorded in real time to achieve data recording.

[0084] In the above scheme, the collected operating parameter signals can be summarized and sent to the database module of the host computer for storage, which can not only monitor and analyze the operating status of the transmitter, but also the on-duty personnel can establish control instructions for the transmitter based on the operating parameter signals and fault instructions to control the transmitter and eliminate transmitter faults.

[0085] Preferably, the host computer further includes a timing control module 23;

[0086] The timing control module 23 is in communication connection with the human-computer interaction module 22;

[0087] The timing control module 23 is used to generate a timing power on / off instruction and send the timing power on / off instruction to the human-computer interaction module 22; the timing power on / off instruction includes a timing power on / off instruction and time information;

[0088] The human-computer interaction module 22 is further configured to respond to the timed power on / off instruction and send the timed power on / off instruction to the lower computer 10 .

[0089] It should be noted that in actual applications, in order to meet the requirements of the radio station's five-frequency FEC broadcasts to be broadcast seven times a day and the weather fax service to be broadcast in different time periods, FEC timed startup and weather fax timed power-on and power-off programs are designed. After the program timer and counter are activated, the power-on and power-off programs will be executed to output corresponding instructions to control the transmitter to automatically turn on and off on time. The power-on and power-off programs for each transmitter are designed. The duty officer initiates the power-on and power-off instructions for each transmitter through the human-machine interface. The instructions remotely power on and off the corresponding transmitter through the subroutine. Through the timing control module, the program timer and counter actions can be automatically transmitted to the lower computer to meet the radio station's periodic power-on and power-off requirements for the transmitter.

[0090] Preferably, the host computer further includes a display module 24;

[0091] The display module 24 is in communication connection with both the database module 21 and the human-computer interaction module 22;

[0092] Then the database module 21 is also used to send the stored operating parameter signals and fault instructions to the display module 24;

[0093] The display module 24 is used to display the operating parameter signal corresponding to the transmitter according to the user's selection; the display module is also used to display the fault instruction.

[0094] It should be noted that in the embodiment of the present invention, the display module filters out the operating parameter signal of the corresponding transmitter from the database module based on the information such as the number or frequency of the transmitter selected by the on-duty personnel obtained from the human-computer interaction module. If there is a fault signal, the fault signal is displayed together with the operating parameter signal.

[0095] See also Figure 3 The embodiment of the present invention further provides a fault monitoring method for a transmitter, and the fault monitoring method is applied to any of the fault monitoring systems for a transmitter as described above, and is specifically performed through steps S1 to S4:

[0096] S1. Collecting operating parameter signals of the transmitter in real time, wherein the operating parameter signals include analog operating parameters and digital operating parameters;

[0097] S2. When the operating parameter signal is greater than a preset threshold, generating a fault instruction according to the operating parameter signal;

[0098] S3, in response to a control instruction, generating a digital output value according to the control instruction; the digital output value corresponds to the digital operation parameter;

[0099] S4. Send the digital output value to the corresponding interface of the transmitter to control the operation of the transmitter.

[0100] A fault monitoring method for a transmitter provided by an embodiment of the present invention can collect and monitor the operating parameter signals of the transmitter and generate a fault signal in real time so as to promptly alert the on-duty personnel, effectively eliminating the problem that the transmitter equipment crashes and causes communication interruption and the on-duty personnel cannot discover it in time; it can also respond to control instructions in time, implement multiple action instructions, logically control the working state of the transmitter, and eliminate transmitter faults in time.

[0101] The present invention may take the form of a computer program product implemented on one or more storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing program code. Computer-readable storage media include permanent and non-permanent, removable and non-removable media, and information storage can be achieved by any method or technology. Information can be computer-readable instructions, data structures, modules of programs, or other data. Examples of computer storage media include but are not limited to: phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, read-only compact disk read-only memory (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices or any other non-transmission medium that can be used to store information that can be accessed by a computing device.

[0102] The above-mentioned embodiments only express several implementation methods of the embodiments of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the embodiments of the present application, and these all belong to the protection scope of the embodiments of the present application.
