Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Example 1: Micro-turbojet engine remote commissioning experimental system

As shown in Figures 1 to 4, the present invention proposes a stable, general-purpose data status collection and remote monitoring multifunctional system, including an equipment status data collection system and a remote service system. The equipment status data collection system includes several Machine equipment end M ₁ -M _n , each machine equipment end includes a monitor and a data acquisition module connected to the monitor for detecting the status parameters of the equipment to be monitored and an equipment controller for controlling the work of the actuator of the equipment to be monitored; The remote service system includes a router gateway, server S, Internet cloud server, client C and WEB monitoring terminal B; the entire system is composed of WEB monitoring terminal B, client C, multiple machine equipment terminals M1-Mn and server terminals The BCM/S structure composed of S is a comprehensive structural design scheme with layers and modules. Among them, client C can be an Android mobile client, IPAD client or iPhone client, and can be accessed using 3G/4G or Internet access.

Taking the micro-turbojet engine remote test experimental system as an example, each machine equipment end (M1-Mn) is mainly composed of the engine's core component controller ECU, a sensor group as a data acquisition module, a monitor and an engine bench. The sensor group Connect to the unified external interface on the monitor and send each detected status parameter to the monitor. As shown in Figure 3, the sensor group includes five temperature sensors and five pressure sensors used to measure the five cross-sections of the micro-turbojet engine inlet, compressor, combustion chamber, turbine and tail nozzle, and is used to monitor the engine. A thrust sensor for thrust, an oil pressure sensor for detecting the fuel oil pressure in the tank, and a temperature sensor for detecting the ambient temperature.

As shown in Figure 3 and Figure 6, the ECU can measure the engine rotor speed and exhaust temperature, condition the measured engine speed signal and send it to the monitor; RS422 can be used to transmit data between the ECU and the monitor. , it can not only export the test run data stored in the ECU memory, but also transmit the control commands sent by the monitor through RS422 to control the starting motor and fuel valve. Therefore, this system has the function of monitoring and controlling engine operation in multiple ways. First of all, the ECU has the ability to independently control fuel pumps, fuel valves, air valves, igniters, starter motors and other actuators. Secondly, the monitor can indirectly control these actuators through the ECU. Finally, in addition to the data collection and remote broadcast capabilities, the monitor also has the function of emergency control of the engine to stop working. When the ECU, host computer monitoring terminal or data remote broadcast capability fails, the monitor can also monitor the oil return connected to it. The three-way valve performs oil return control, quickly changes the flow direction of the fuel, stops the fuel supply to the engine, and then realizes direct control of the engine and realizes emergency stop of the engine. Of course, RS232 communication can also be used for data transmission between the ECU and the monitor.

As shown in Figure 3, the monitor analyzes and processes the received status parameters (the status parameters sent by the sensor group and the adjusted rotation speed and exhaust temperature parameters sent by the ECU). On the one hand, the processed parameters are processed through the RS232 serial port. The status data is sent to the movable panel and the host computer monitoring terminal, and is displayed to the operator in the form of numbers and dynamic curves; on the other hand, the data packets are sent through the router gateway through the TCP/IP protocol with the help of its own Ethernet data transmission function. Send it to the server S and Internet cloud server in the remote service system to realize data storage.

The structure of the movable panel can be shown in the lower left corner of Figure 3 and Figure 6. The panel is equipped with a start button, a stop button, an emergency stop button and an LCD screen for displaying real-time equipment status data. The LCD screen will display real-time equipment status data. The status data is displayed in the form of numbers and dynamic curves. The operator can manually intervene in the operation of the engine by observing the LCD on the movable panel and the data displayed by the MFC host computer. At the same time, due to the high risk factor of the running engine, the test bench and the operator must be isolated. As shown in Figure 9, a transparent vacuum bulletproof isolation wall can be installed between the test bench and the operation panel to ensure the safety of the operator. Personal safety. The upper computer monitoring terminal can view engine status data and send control engine operation instructions. It must be verified by the user and the corresponding authority can be obtained before the corresponding operation can be performed. After the user verification is passed, the real-time status data can be sent to the monitor. Issue corresponding operation instructions. At the same time, WEB monitoring terminal B and client C can also view engine status data and control the sending of engine operating instructions. They must pass user verification and obtain the corresponding permissions before performing corresponding operations; after the user verification is passed, WEB monitoring Terminal B and client C can directly obtain the real-time status data of the device from the Internet cloud server, and issue corresponding operation instructions to the monitor based on the real-time status data. When the monitor receives the operation command from the host computer monitoring terminal, WEB monitoring terminal B or client C, the monitor is responsible for converting it into a control signal and sending it to the ECU, indirectly realizing short-range and remote monitoring of the engine through the ECU. .

The above-mentioned server S refers to the Java web service program and database service running on the tomcat server. It is mainly responsible for monitoring the test run status of the engine, continuously saving test run data, and responding to network requests from WEB monitoring terminal B and client C. As shown in Figure 1, Figure 2 and Figure 4, real-time monitoring of engine status mainly collects real-time data of the engine through hardware interfaces; saving test run data mainly means storing the collected data in the Oracle database of server S to meet the data needs. and playback; the network request of WEB monitoring terminal B is mainly to enable the server's network monitoring. When the user accesses the corresponding web page on the Server server through WEB monitoring terminal B, the Server server can return the corresponding data to the user according to the value of the user's request data. data. Server-side S opens up a unique listening thread to monitor the connection and disconnection status of the monitor. Because the number of engine test benches is limited (up to 255 units), the number of IP addresses automatically assigned to the monitor by the local router gateway meets the conditions. WEB monitoring terminal B or client C can realize concurrent access to the server by multiple users. In addition, the JavaWeb server background program Java service program is also responsible for storing temporary data in the database.

In general, the front-end web page uses HTML, CSS and JavaScript to realize online virtual control, remote real-time data display, personnel management and login verification; the Servlet container of the Javaweb background service program is implemented by multi-thread programming, and Servlet technology can be used to process the network Request to open a dedicated server-side listening thread for monitoring hardware connection information. According to the actual situation, the server-side application can be deployed to a preset server or Internet cloud server host to realize the remote access function; the server-side JavaBean formats the data into Json data format, and transfers the JSON format data through AJAX transmission. Transmit to front-end JS for data analysis.

Among them, Servlet (Server Applet), the full name of Java Servlet, is a server-side program written in Java, a program that runs on a Web server or application server. It serves as a request from a Web browser or other HTTP client and on the HTTP server. The middle layer between databases or applications, its main function is to browse and modify data interactively and generate dynamic Web content. The specific working principle is: the client sends a request to the server; the server sends the request information to the Servlet; the Servlet generates the response content and passes it to the server. The response content is generated dynamically, usually depending on the client's request; the server returns the response to the client. Java Servlet can usually achieve the same results as programs implemented using CGI (Common Gateway Interface, public gateway interface), but its performance is significantly better than CGI. For example: Servlet is executed within the address space of the Web server, eliminating the need to create a separate process to handle each client request. Servlet opens a dedicated server-side listening thread for monitoring and hardware connection information. Depending on the actual situation, the server-side application can be deployed to a preset server or cloud server host to realize the remote access function; the server-side JavaBean formats the data Convert it into Json data format, and transmit the JSON format data to the front-end JS for data analysis through AJAX transmission. Among them, the full name of AJAX is Asynchronous JavaScript and XML. It is a technology that can quickly create dynamic web pages and achieve asynchronous updates of web pages without refreshing.

The web page of WEB monitoring terminal B sends a request to the server at a speed of 200ms to obtain real-time data. The request code uses the AJAX interface function of JQuery. After receiving the network request from the WEB monitoring terminal B, the server S reads the real-time data of the engine. The server returns the data to WEB monitoring terminal B in a certain data format. After WEB monitoring terminal B receives the network response from the server, it parses it and obtains the data. WEB monitoring terminal B dynamically displays data on the browser interface through the Echarts graphics library. Among them, the real-time data transmission process is shown in Figure 12.

The dynamic display of specific data can be seen in Figure 13. This system mainly uses two graph types: line chart and dashboard for data visualization. As shown in Figure 13, the pressure and temperature items on the left are displayed using a line chart, and each item contains five sets of data, namely: inlet, compressor, combustion chamber, turbine, tail injection Five typical cross-sections of tubes. The four items of thrust, oil volume, speed, and flow on the right are displayed in the form of a dashboard, which is more in line with usage habits.

In addition, when allowing users to view all engine data on the bench, we can make the following extension: when WEB monitoring terminal B requests engine data, certain data is carried in the network request, and the data can is the number of the engine. Users can request the data of their specified engine through this request. At this time, corresponding modifications must also be made on the server side. When processing the network request of WEB monitoring terminal B, the data carried in the network request (such as the engine number) must be obtained first, and then the real-time engine number of the corresponding bench must be returned based on this number. data. The logic of WEB monitoring terminal B accepting the server-side network response does not need to be changed in any way.

Preferably, on the one hand, the monitor packages the status data into a customized serial port protocol package, and then realizes data transmission through the serial port to Ethernet module. The monitor can be configured in fixed IP and ClientSocket mode, and the server S is configured in ServerSocket mode. , the server S starts a listening thread to specifically monitor the connection request of the ClientSocket. When the connection between the client and the server is successful, the server S can accept the TCP/IP protocol packet, and then parses the received protocol packet, and the JavaBean class of the server S is successfully loaded. For the data in the protocol package, the Servlet formats the data loaded by the JavaBean class into Json data format. Next, the Json data is transferred to the front-end requested page through Ajax asynchronous data transmission; when the page gets the Json data format, the front-end page By parsing the Json data format in Jquery, echart can display the parsed data as a dynamic curve. On the other hand, the monitor transmits the data to the C++ program in the host computer monitoring terminal through RS232 communication in the form of serial port protocol; the C++ program performs protocol analysis on the customized protocol package and uses NI controls to realize the dynamic graphics of the data. show.

The internal and external electrical structure of the above-mentioned monitor is shown in Figure 5 and Figure 6. The monitor uses the TM4C123GH6PZ processor as the core and also includes a current conditioning circuit, a PWM frequency conditioning circuit, a voltage conditioning module, a MOS valve drive circuit, and a 24V to 5V converter. Conditioning module and 5V to 3.3 conditioning module, etc. The external interfaces mainly include V0, V1, F0, F1, TX+, TX-, RX+, RX-, DJ0, DJ1, DJ2, RXD, TXD, +24V, GND, and can receive I-0 to I-12 for 4-20mA analog current.

The TM4C123GH6PZ processor integrates 256K single-cycle Flash memory, built-in 32K ROM, 16 universal asynchronous receivers and transmitters UART, LAN controller CAN, 16 pulse width debugger PWM inputs and outputs, and 22 ADC converters. I-0 to I-4 and I-7 to I-11 can correspondingly receive temperature and pressure analog current signals from the five sections of the engine inlet, compressor, combustion chamber, turbine and tail nozzle. As shown in the figure The current conditioning circuit in 11 is input to the internal ADC analog-to-digital converter of the AMR chip, and the analog signal is converted into a digital signal. I-5 receives the liquid level signal collected by the liquid level sensor, I-6 receives the starting thrust signal collected by the thrust sensor, I-12 receives the oil pressure signal collected by the oil pressure sensor, and F1 receives the flow signal collected by the flow sensor. V1 collects the signal of manually adjusting the throttle lever. F0 and V0 correspond to receiving the engine speed signal and engine exhaust signal transmitted from the ECU. DJ0 is connected to the start control (switch button), DJ1 is connected to the emergency stop (switch button), and DJ2 is connected to the oil return valve. Through the valve, TX+ is the sending end+ for RS422 communication with ECU, TX- is the sending end- for RS422 communication with ECU, RX+ is the receiving end+ for RS422 communication with ECU, RX- is the receiving end for RS422 communication with ECU. terminal -, RXD is the sampling data output RS232 receiving terminal, TXD is the sampling data output RS232 output terminal, +24V is the input terminal for power supply DC 24V, and GND is the general ground terminal. As mentioned above, the driving circuit schematic diagram of the DJ2 interface oil return three-way valve is shown in Figure 12. The PWM frequency conditioning circuit is shown in Figure 13 and Figure 14. Figure 13 can condition the flow signal collected by the F1 interface, and Figure 14 can condition the engine speed signal received by the F0 interface. Interfaces I-0 to I-11 are general interfaces for data acquisition, and their circuit design principles are the same as those in Figure 11. That is, interfaces I-0 to I-11 are respectively connected to a current conditioning circuit that is the same as Figure 11. For each The signals received by each interface are respectively current-conditioned. The voltage conditioning module includes three sub-circuits, which are connected to interfaces V1, V0 and the ambient temperature signal acquisition interface respectively. The circuit design schematic diagram corresponding to interface V1 is shown in Figure 15, and the circuit design schematic diagram of interface V0 is shown in Figure 16. Environment The circuit design principle diagram of the temperature signal acquisition interface is shown in Figure 17.

Among them, each sampling channel of the TM4C123FH6PM microcontroller has two built-in identical analog-to-digital converters ADC0 and ADC1. As shown in Figure 11, the two ADC modules work independently of each other, so different sampling sequences can be executed at the same time, and any sampling sequence can be executed at any time. An analog input channel is sampled and generates various interrupt and trigger events.

The PCB of the monitor has a four-layer structure, which is divided into Top signal layer, Middle power layer and ground layer, and Bottom signal layer from top to bottom. The PCB circuit board design and wiring are isolated from the digital ground wire and the analog ground wire. There is an isolation zone between the analog signal area and the digital signal area. A large area of copper is laid in the power supply area to help assist heat dissipation.

In view of the complexity of the structure of the micro-turbojet engine bench test experimental system, the structural design of the experimental system must be reasonable, the structure should be clearly divided, and the functions should be diversified. As shown in Figure 7, the system structure can be roughly divided into: sensor and actuator layer, ECU control layer, monitor monitoring layer, data layer, and user layer; only the external interface definitions are consistent between layers. The specific implementation methods within the layer are relatively independent. The engine has the characteristics of high operating speed, large thrust, and high experimental risk; in case of emergencies, this system has a variety of emergency measures.

Considering that a good power supply system is a prerequisite to ensure the normal operation of the system, and the engine has many actuators and sensors, the power supply characteristics should be kept as consistent as possible. If the voltage required by each component of the designed system is different, it will bring great trouble to the system in terms of power supply and experimental system layout, and the overall volume and weight of the test bench will also increase. The power supply system design scheme of this micro-generation experimental system is shown in Figure 8. The input is a 220V AC voltage power supply. After the filter and AC/DC voltage conversion conditioning module, the output is a 24V DC voltage. Among them, the power supply of the monitor, ECU, sensor and actuator, and motor are all designed to use 24V DC voltage; the power indicator light shows the status of the power supply.
