[0047] One end of resistor R6 is connected to pin 3 of terminal P1, and the other end is connected to pin 3 of comparison chip U3. Pin 2 of comparison chip U3 is connected to pin 1 of terminal P1. Pin 1 of comparison chip U3 is connected to resistor R3 and pin 3 of trigger chip U1. Pin 5 of comparison chip U3 is connected to resistor R5, and pin 6 is connected to pin 2 of terminal P1. Pin 7 of comparison chip U3 is connected to resistor R4 and pin 11 of trigger chip U1. Pin 4 of comparison chip U3 is grounded. The other ends of resistors R3 to R5 are all connected to pin 3 of terminal P1, and pin 8 of comparison chip U3 is also connected to pin 3 of terminal P1.

[0048] Terminals P3~P4 are all connected to the protection isolation circuit.

[0049] Pin 1 and pin 13 of the trigger chip U1 are connected to the protection isolation circuit, pin 2 and pin 12 are connected to the status display circuit, pin 4 and pin 10 are connected to terminal P4, and pin 6 and pin 8 are grounded. Pin 5, pin 9, and pin 14 of the trigger chip U1 are all connected to pin 3 of terminal P1.

[0050] The status display circuit includes light-emitting diode LED1 and light-emitting diode LED2. Pin 2 of the trigger chip U1 is sequentially connected to light-emitting diode LED1 and resistor R1, and pin 12 of the trigger chip U1 is sequentially connected to light-emitting diode LED2 and resistor R2. Resistor R1 and resistor R2 are short-circuited and then connected to pin 3 of terminal P1.

[0051] The protection isolation circuit is an optocoupler U2. Pin 1 and pin 3 of the optocoupler U2 are respectively connected to pin 1 and pin 13 of the trigger chip U1, and pin 2 and pin 4 of the optocoupler U2 are grounded; pin 8 and pin 6 of the optocoupler U2 are both connected to pin 1 of terminal P4, and pin 7 and pin 5 of the optocoupler U2 are correspondingly connected to pin 1 and pin 2 of terminal P3; pin 2 of terminal P4 is connected to pin 4 and pin 10 of the trigger chip U1.

[0052] The comparison chip U3 is NJM2904M, the trigger chip U1 is TC4013BP, the model of the optocoupler U2 is ORPC-827B, the terminal P1 is WJ2EDGK, and the terminals P3 - P4 are WJ500V.

[0053] Terminal P1 is electrically connected to the CFR-87-71 noise filter board of the exciter in the JRC transmitter. The analog signals in the CFR-87-71 noise filter board include but are not limited to: the transmitter output power Po, the forward voltage signal Vf for calculating the transmission standing wave ratio, and the reverse voltage signal Vr.

[0054] The digital signals of the JRC transmitter include but are not limited to one or more of the following: the transmitter power amplifier operation on PAON, the power supply overvoltage PS OV, the power supply overcurrent PSOC, the power supply fuse PS FUSE, the transmitter power supply on PWR ON, and the power amplifier alarm PAALM.

[0055] The lower computer uses a programmable logic controller (PLC). The PLC is a data operation electronic system specifically applied to industrial production processes. The PLC processes the collected on-site data through a programmable storage unit and has extremely high stability, reliability, and adaptability. The Siemens S7-200 series PLC is selected as the signal processing center of the JRC transmitter fault status monitoring system. To meet the domestic demand, it can be changed to domestic PLCs such as Inovance and XINJE.

[0056] The relevant signals collected from the JRC transmitter are sent into the PLC through the DI and AI modules for data processing to achieve the signal acquisition function. Later, through the DO digital output module of the PLC and a 24V intermediate relay, the relevant control signals such as the power-on and power-off signals to control the transmitter are sent into the corresponding interface board in the transmitter exciter to achieve the logical operation control of the transmitter.

[0057] The CPU control master station of the PLC is connected to each I / O sub-station distributed in the machine room site through optical fiber, Modbus communication or EtherCAT bus to collect various analog and digital signals of the transmitter operating status. Later, the CPU runs the preset program and sends corresponding instructions to each transmitter through the output module, and relies on the action of the intermediate relay to achieve the control of the transmitter by the PLC.

[0058] The communication between the PLC and the upper computer monitoring computer selects the RJ45 Ethernet interface to achieve Ethernet communication connection, which can achieve faster and more stable program / data download, better real-time performance, supports the PLC to access the Internet, and realizes operations such as remote search, online monitoring, upload and download of the PLC. It can directly establish a connection with each variable of the upper computer human-machine monitoring interface, and the operation convenience is good.

[0059] To meet the requirement that the transmitter status and fault alarm information can be pushed to relevant staff in real time, it is necessary to realize the remote upload / download program and device data monitoring of the PLC and the monitoring screen through the Internet of Things network. The system Internet of Things network is as follows Figure 6 shown.

[0060] The Internet of Things network module plays a connecting role in the entire JRC transmitter fault status monitoring system. It collects the data processed by the JRC transmitter signal acquisition system and the PLC downward, and transmits the data to the Internet of Things cloud operation platform upward. This module can select the Xinjie A-BOX series products, which have simple network configuration, do not require professional technology, are easy to use, support technologies such as 4G full network communication, GPS global positioning, serial port transparent transmission function, and Ethernet VPN, and meet the requirements of the JRC transmitter fault status monitoring system based on the Internet of Things.

[0061] The logical function of the JRC transmitter fault status monitoring system is mainly realized through the lower computer PLC program. The PLC calculates and processes the signals collected from the JRC transmitter signal acquisition circuit. Through the sequential execution of the PLC program, the PLC program communicates with the upper computer, summarizes and sends the collected operating status information of each transmitter to the upper computer human-machine interface. The duty personnel can monitor the JRC transmitter fault status in real time from the monitoring computer interface. The second-phase function can receive the upper computer instructions, and according to the operation results of the duty personnel on the upper computer, output the results from the monitoring terminal to each output module, and then control the working status of the transmitter through the intermediate relay.

[0062] According to the system design requirements, the PLC program mainly designs the following programs:

[0063] 1. Action detection and feedback program: After the power-on / off and exciter subroutine calls, this program is enabled to detect whether the corresponding actions are completed. If not, the subsequent operations are stopped and a fault alarm is issued. If completed, the corresponding action status is output to the monitoring interface for display.

[0064] 2. Fault monitoring program: This program is enabled after the transmitter is powered on to monitor the operating parameters of the transmitter in real time. It mainly monitors three analog signals Po, Vf, Vr and six digital signals PAON, PS OV, PSOC, PS FUSE, PWR ON, PA ALM collected by the acquisition circuit. Once the operating parameters are greater than or less than the preset parameters, a fault signal is generated and reported to the human-machine interface for alarm. The duty personnel will take further actions after discovering the alarm.

[0065] 3. Timed power-on / off and regular power-on / off program: To meet the requirements of the radio station for 7 daily timed broadcasts of five-frequency FEC and the time-segmented broadcast of meteorological facsimile services, the FEC timed power-on and meteorological facsimile timed power-on / off programs are designed. After the program timer and counter act, the power-on / off program is executed to output the corresponding instructions to control the transmitter to automatically turn on and off on time. The power-on / off programs of each transmitter are designed. The duty officer issues power-on / off instructions for each transmitter through the human-machine interface, and the instructions perform remote power-on / off operations on the corresponding transmitter through the subroutine.

[0066] 4. Exciter control program: This program is used to perform related operations on the transmitter exciter such as preset frequency selection, broadcast mode selection, and transmit power level selection. When the duty officer remotely controls the transmitter through the human-machine interface, this program is called, and the corresponding PLC interface is as Figure 7 shown.

[0067] The human-machine interface (HMI), also known as the user interface, is the interface for information transfer and dialogue between humans and computers. The main functions of the Internet of Things network human-machine monitoring interface of the JRC transmitter fault status monitoring system are: status monitoring, fault alarm, and control operation. Through configuration software such as Touch Win Pro, Kingview, and MCGS, the duty personnel can intuitively monitor the operating status of each JRC transmitter; by setting the OPC service, a data connection is established between the upper human-machine interface and the lower PLC, and the dynamic data of the PLC is reflected on the human-machine interface in real time. The duty officer can set and control each transmitter; by using the built-in database function of the configuration software, various parameters of the operating status of each transmitter such as frequency, power, and standing wave ratio are automatically recorded and a record table is created, and the fault alarms are recorded in real time to achieve data recording.

[0068] Figure 8 The figure shows the HMI main interface of the JRC transmitter fault status monitoring system. In the first phase of the plan, 10 JRS-700 series transmitters currently in use at the transmitting station will be connected to the host computer. The on-duty operators can enter the real-time monitoring screen of the selected transmitter by clicking on the icon of the corresponding numbered transmitter through the display terminal operation. Figure 9 The figure shows the monitoring interface when the JRC transmitter is operating normally.

[0069] In the normal operation monitoring interface of the JRC transmitter, two circular charts are used to display the real-time forward power and reverse power of the current transmitter. The working mode and working frequency information of the selected transmitter are shown in the lower left corner. The fault lights of the power amplifier unit and the power supply unit are respectively in the lower right corner of the monitoring interface. When any alarm occurs in the transmitter, the transmitter stops working and the relevant fault status is displayed on the monitoring interface. Figure 10 The figure shows the real-time monitoring screen when the power amplifier alarm occurs in the transmitter.

[0070] The JRC transmitter fault status monitoring system monitors the remote device data of PLC, touch screen, and human-machine monitoring interface based on the Internet of Things. Through the Internet of Things network, remote dynamic monitoring, fault alarm, control operation, and data record query of JRC status information can be realized.

[0071] This system can select platforms such as Alibaba Cloud and XINJE Cloud Manufacturing to realize cloud data processing. The cloud service platform has the characteristics of no programming and no software installation, and can be quickly and conveniently connected. It can realize remote control of the device through WEB and APP at any time. Figure 11 It is the initial monitoring platform designed for using the domestic XINJE Cloud Manufacturing platform. Through the cloud interface, remote data monitoring, parameter setting, and function control of the JRC transmitter fault status monitoring system can be directly carried out.

[0072] As Figure 12 Shown in the figure, the configuration large screen of the JRC transmitter fault status cloud monitoring system can dynamically display the main and standby quantities of the transmitting station transmitter equipment, fault records, maintenance information, etc., which is convenient for relevant staff to view remotely.

[0073] As Figure 13 Shown in the figure, relevant staff can also receive the alarm information of the transmitting station transmitter in real time through the WeChat official account alarm push. They can click Settings >> Click Push >> Turn on the WeChat official account alarm switch >> Scan the WeChat public account >> Bind the platform push account in the device configuration interface of the cloud manufacturing.

[0074] As can be seen from the above discussion, the utility model can assist in realizing the remote monitoring of the transmitter of the short-wave transmitting station, providing technical support for the construction of a smart radio station; relevant staff can selectively receive the alarm information pushed by the transmitter in real time, discover problems in a timely manner, and ensure the real-time smoothness of communication; it improves the automation and intelligence level of the operation of the transmitting system, and effectively improves the reliability and stability of the signal transmission work of the short-wave transmitter.
