[0031] The present invention will be further described with reference to the accompanying drawings and specific embodiments:

[0032] Figure 1 1 is a system block diagram of the present invention, a multi-threaded data simulator embedded device includes a monitoring processing unit 1, a data generating unit 2, a data sending control unit 3 and a temperature monitoring alarm unit 4.

[0033] The monitoring processing unit 1 includes an independent thread that receives control information and query information from the monitoring system via the gigabit network port. The control information includes various setting parameters such as service type, information format, data packet length, sample size, designated sending network port, sending mode, sending rate, start sending, and stop sending. The query information is a query instruction for querying the parameters currently used by the data generation unit 2 and the data transmission control unit 3. The monitoring processing unit 1 is used to process the monitoring control information, sending the service type, information format, and data packet length setting parameters therein to the data generation unit 2, and sending the sample size, designated sending network port, sending mode, sending rate, and start sending and stop sending setting parameters to the data transmission control unit 3. The monitoring processing unit 1 is also used to calculate the parameters currently used by the data generation unit 2 and the data transmission control unit 3 based on the query information and report it to the monitoring system.

[0034] The data generation unit 2 includes an independent thread for generating business data of a specified type according to the setting parameters such as business type, information format, data packet length, etc. issued by the monitoring processing unit 1, and sending the business data to the data sending control unit 3.

[0035] The data sending control unit 3 includes three independent threads, which are used to send the business data generated by the data generation unit 2 from the sending network port specified by the monitoring processing unit 1 to the channel in the form of a stable business data stream based on the sample size, sending mode, sending rate and start sending and stop sending setting item parameters issued by the monitoring processing unit 1.

[0036] The temperature monitoring and alarm unit 4 includes an independent thread for real-time monitoring of the temperature of the entire device and triggering an alarm when the temperature is abnormal.

[0037] Figure 2 This is a block diagram of the monitoring processing unit 1 of the present invention. This unit includes a setup item processing module 5 and a query item processing module 6. Because the processing system (PS) offers advantages over programmable logic (PL) in sending, receiving, and parsing UDP packets, such as high flexibility, ease of debugging, and a rich protocol stack, monitoring processing unit 1 was developed on the PS side.

[0038] The setting item processing module 5 is used to verify the legitimacy of the control information issued by the monitoring, and to issue an alarm for abnormal situations. After the verification is passed, the service type, information format and data packet length setting item parameters are sent to the data generation unit 2, and the sample size, designated sending network port, sending mode, sending rate and start sending and stop sending setting item parameters are sent to the data sending control unit 3; the query item processing module 6 is used to verify the legitimacy of the query information issued by the monitoring, and to issue an alarm for abnormal situations, and to extract the parameter query content from the query information that has passed the verification, and report the parameters currently used by the data generation unit 2 and the data sending control unit 3 to the monitoring processing unit 1.

[0039] Figure 3 The data generation unit 2 of the present invention comprises a comprehensive service generation module 7, a collaborative service generation module 8, a navigation service generation module 9, a point trace service generation module 10 and a special format service generation module 11. The data generation unit 2 is also developed on the PS side.

[0040] The data generation unit 2 receives the control information from the monitoring processing unit 1, and the service types include integrated service, collaborative service, navigation service, trace service and special format service; the corresponding service generation module generates service data of the specified type based on the setting item parameters, and sends it to the data sending control unit 3; for example, when the service type in the control information received from the monitoring processing unit 1 is integrated service, the integrated service generation module 7 generates service data of the specified type based on the setting item parameters, and sends it to the data sending control unit 3.

[0041] The information formats supported by the comprehensive service generation module 7 and the collaborative service generation module 8 include: all "0" data, all "1" data, "0" and "1" alternating data, PN code data, etc.; the navigation service generation module 9 supports the definition of longitude and latitude coordinates, altitude, heading, speed and selection of sending network ports, etc.; the point trace service generation module 10 supports the definition of the distance, azimuth, pitch angle, moving direction, moving speed and other contents of multiple nodes; the special format service generation module 11 supports the generation of specified content service data suitable for maritime communications according to needs.

[0042] Figure 4 The figure is a module structure diagram of the data transmission control unit 3 of the present invention. The data transmission control unit 3 includes a rate control monitoring module 13, a transmission frame number statistics module 12, and a timing module 14. The transmission frame number statistics module 12, the rate control monitoring module 13, and the timing module 14 each include an independent thread. Based on the advantage of PL having high timing accuracy, the timing module 14 of the present invention is developed on the PL side. When the timing module counts the full timing period Δt, the PS side receives a trigger signal, and the rate control monitoring module 13 accumulates the amount of data to be sent within the timing period Δt. Therefore, the data transmission control unit 3 adopts a PS and PL joint development model.

[0043] The sending frame number statistics module 12 is used to receive the sample size and the setting item parameters of the designated sending network port sent by the monitoring processing unit 1, and to count the number of service data stream frames sent to the channel through the designated network port. When the set sample size is reached, the designated network port stops sending data frames. The rate control monitoring module 13 is used to receive the sending mode, sending rate, and the setting item parameters for starting and stopping sending sent by the monitoring processing unit 1. When the setting item parameters for starting and stopping sending are in the start sending state, the service data stream is started to be sent from the designated network port to the channel according to the sending mode parsed by the monitoring processing unit 1, and the clock is obtained from the timing module 14. The expected cumulative amount of sent data is calculated based on the sending rate issued by the monitoring processing unit 1, and the flow compensation algorithm is executed in the continuous data transmission cycle to control the sending rate of the service data stream according to the sending rate parameters.

[0044] Figure 5This is a module structure diagram of the temperature monitoring and alarm unit 4 of the present invention. The temperature monitoring and alarm unit 4 includes a temperature query module 15 and an alarm control module 16. Both the temperature query module 15 and the alarm control module 16 are jointly developed on the PS and PL sides. The temperature query module 15 on the PL side is used to obtain the device temperature and report it to the temperature query module 15 on the PS side. The temperature query module 15 on the PS side then sends the temperature to the alarm control module 16 on the PS side. The alarm control module 16 on the PS side determines whether the temperature is abnormal. If an abnormal temperature is detected, the PS side alarm control module 16 sends a temperature abnormality trigger instruction, which controls the alarm control module 16 on the PL side to drive the LED to flash and alarm, thus implementing a visual alarm feedback mechanism for abnormal temperatures.
