[0038] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0039] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0040] Some exemplary embodiments of the present invention are described for the purpose of illustration. It should be understood that the present invention may be implemented in other ways not specifically shown in the drawings.

[0041] Figure 1 1 is a schematic structural diagram of an embodiment of a fuel control system 1 for an aviation flight simulator of the present utility model. Figure 1 As shown, the fuel control system 1 for an aviation flight simulator provided by the embodiment of the utility model may include: a simulated fuel control device 100 and a system measurement and control device 200; the simulated fuel control device 100 is connected to the system measurement and control device 200 via a field bus.

[0042] It can be understood that in this embodiment, the system measurement and control device 200 and the simulated fuel control device 100 communicate from top to bottom using the field bus, that is, the system measurement and control device 200, Ethernet, gateway, communication protocol, interface unit, and simulated fuel control device 100 are all connected through the field bus, so that the simulated fuel control device 100 can be accessed, collected, and controlled by relying only on a pair of twisted pairs. At the same time, this system unit interconnection method makes it extremely convenient to expand, add, or change the system function module, because the entire system is based on a highly flexible, expandable, and open interconnection interface, without having to change its topological connection structure on a large scale. It can be seen that compared with the traditional system unit interconnection method, the field bus greatly simplifies the connection between the simulation devices, greatly reduces the number and complexity of the connection cables, and can improve the reliability, maintainability, and standardization of the system.

[0043] Specifically, the system measurement and control device 200 is used to send a query instruction to the simulated fuel control device 100, and receive action status information sent by the simulated fuel control device 100 based on the query instruction, and / or send a control instruction to the simulated fuel control device 100.

[0044] Specifically, the simulated fuel control device 100 is used to receive the query instruction and / or control instruction, send the action status information to the system measurement and control device 200 according to the query instruction, control the target object to perform the target action according to the control instruction, so as to collect and store the action status information.

[0045] In this embodiment, the simulated fuel control device 100 and the system measurement and control device 200 are communicated and connected by means of a field bus, so that the simulated fuel control device 100 can be accessed, collected and controlled only by relying on the field bus, which greatly simplifies the connection between the electrical nodes and greatly reduces the data and complexity of the connecting cables, thereby improving the reliability, maintainability and standardization of the system.

[0046] Figure 2 The figure is a schematic structural diagram of a preferred embodiment of a fuel control system for an aviation flight simulator of the utility model. Figure 2 As shown, in the fuel control system 1 for an aviation flight simulator of this embodiment, the simulated fuel control device 100 may include a collection module 110 and a processing module 120 .

[0047] Among them, the acquisition module 110 is used to collect the action status information of the target object performing the target action, and send the action status information to the processing module 120; the processing module 120 is used to control the target object to perform the target action when receiving the control instruction, collect the action status information and store it; when receiving the query instruction of the system measurement and control device 200, the action status information is sent to the system measurement and control device 200.

[0048] In practical applications, such as Figure 3 As shown, the acquisition module 110 includes an analog quantity acquisition unit and a digital quantity acquisition unit; the analog quantity acquisition unit is used to acquire analog quantity information and send it to the processing module 120; the digital quantity acquisition unit is used to acquire first digital quantity information and send it to the processing module 120; wherein the analog quantity information and the first digital quantity information are both the action status information.

[0049] Exemplarily, the digital quantity acquisition unit includes a general-purpose input / output interface (GPIO) for collecting switch output data and switch input data of the target object, and sending the switch output data and the switch input data as the first digital quantity information to the processing module 120.

[0050] Exemplarily, the analog quantity acquisition unit includes a constant current source CC, an analog quantity signal source and an analog-to-digital converter AD; the constant current source CC and the analog quantity signal source are both connected to the analog-to-digital converter AD; the constant current source CC is used to provide electrical energy to the analog quantity signal source and the analog-to-digital converter AD; the analog quantity signal source is used to provide analog quantity information of the target object; the analog-to-digital converter is used to convert the analog quantity information into corresponding second digital quantity information and send it to the processing module 120.

[0051] In practical applications, the processing module 120 includes a communication unit (ie Figure 3 a data communication interface in the figure), a storage unit (not shown) and a processing unit MCU; the processing unit MCU is used to receive the query instruction and the control instruction through the communication unit; according to the query instruction, the action state information is obtained, and the action state information is sent to the system measurement and control device 200 through the communication unit; according to the control instruction, the target object is controlled to perform the target action to collect the action state information; the storage unit is used to store the action state information.

[0052] It should be noted that, in this embodiment, the simulated fuel control device 100 can read the action status information from the storage unit only when the system test device actively sends a query command, so as to avoid bus conflicts.

[0053] The target object may be, for example, various simulated switches, indicator lights, potentiometers, etc. When the target object included in the control instruction is various switches, the target action may be to close the switch or to open the switch. When the target object included in the control instruction is an indicator light, the target action may be, for example, to light up the indicator light, to light up the indicator light constantly or to flash the indicator light. This embodiment does not specifically limit the target object and target action included in the test command, and may be determined according to the actual test situation.

[0054] In one example, the storage unit may be a register, and the processing unit may be a microcontroller unit (MCU). After the MCU collects the action state information, the action state information may be stored in the register. Upon receiving a query instruction, the action state information is read from the register in a prescribed message format, and the action state information is filled into the message as the action state information and sent to the system measurement and control device 200.

[0055] In one embodiment, Figure 3 As shown, the simulated fuel control device 100 may further include: a driving module and a light guide plate. The driving module is connected to the processing module 120 and the light guide plate respectively; the driving module is used to drive the light guide plate according to the control of the processing module 120.

[0056] For example, the driving module may be a pulse width modulation (PWM) constant current driving source. The driving module may perform operations such as brightness adjustment of the light guide plate according to the control of the processing module 120 .

[0057] It can be seen that in this embodiment, the simulation fuel control device 100 is based on the processing unit as the core, plus a number of necessary functional circuits, such as switch debounce, GPIO interface, filter, analog-to-digital converter, constant current source, PWM constant current drive source and other specific circuit environments, to complete the data acquisition, transformation and digitization of switch quantity and analog quantity, and realize the dimming function of indicator light and light guide plate. Finally, it is controlled by the processing unit and connected to the serial bus through their respective interfaces, and finally a network is built through the gateway, LAN-bus and system test equipment to achieve interconnection. This greatly simplifies the connection between each electrical node, greatly reduces the data and complexity of the connection cables, and thus improves the reliability, maintainability and standardization of the system.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
