Embodiment 1

[0022] figure 1 The implementation process of the management method of the spaceborne equipment provided by the first embodiment of the present invention is shown. A virtual image of the spaceborne equipment is set between the system application layer and the lower service layer of the system, and the method is described in detail as follows:

[0023] In step S101, the application program of the system application layer sends a control instruction for the spaceborne equipment to the virtual image of the spaceborne equipment, where the control instruction includes an identifier of the spaceborne equipment.

[0024] Specifically, as figure 2 Shown is a schematic structural diagram of the spaceborne system of the present invention, which sequentially includes a system application layer, a virtual image of spaceborne equipment, a system lower-layer service layer, and a spaceborne equipment from top to bottom. The system application layer according to the embodiment of the present...

Embodiment 2

[0037] image 3The implementation process of the management method of the spaceborne equipment provided by the second embodiment of the present invention is shown. A virtual image of the spaceborne equipment is set between the system application layer and the lower service layer of the system, and the method is described in detail as follows:

[0038] In step S301, the on-board device virtual image detects whether any on-board device is connected to the system.

[0039] As the spaceborne equipment is being tested or maintained, new spaceborne equipment may be connected, or the access interface of the spaceborne equipment may be replaced. Once the onboard equipment is replaced, the onboard equipment management program in the prior art needs to redefine its communication lines and interfaces, and the modified program needs to be compiled before it can continue to move, which affects the operating efficiency of the system.

[0040] In the present invention, by setting the virtua...

Embodiment 3

[0052] Figure 4 The implementation process provided by the third embodiment of the present invention is shown, and the details are as follows:

[0053] In step S401, the on-board device virtual image detects whether an on-board device is connected to the system.

[0054] In step S402, the virtual image of the on-board device determines whether there is an identifier of the on-board device connected to the system in the enumeration list, and if so, according to the port of the on-board device connected to the system, Correspondingly adjust the correspondence between the identifier of the onboard device in the enumeration list and the service interface of the lower layer service layer of the system.

[0055] Different from the second embodiment, the embodiment of the present invention directly changes the stored enumeration list when detecting that the on-board device identifier of the on-board device connected to the system exists in the enumeration list, thereby correcting t...

Abstract

The present invention is applicable to the aerospace field, and provides a management method and device for spaceborne equipment. A virtual image of the spaceborne equipment is set between the system application layer and the service layer of the system lower layer. The method includes: the application program of the system application layer sends The virtual image of the on-board device sends a control instruction to the on-board device, and the control instruction includes the identifier of the on-board device; the virtual image of the on-board device, according to the identifier of the on-board device included in the control instruction, In the enumeration list of the identifier of the set onboard device and the service interface of the lower layer of the system, search for the device access function corresponding to the identifier of the onboard device; The device sends the control instruction. When the device is changed, the present invention does not need to rewire and modify the corresponding management program, which is beneficial to reduce the burden of developers and improve the replacement efficiency of spaceborne devices.

Description

technical field [0001] The invention belongs to the field of aerospace, and in particular relates to a management method and device for on-board equipment. Background technique [0002] In the satellite system, a plurality of on-board devices are included, and the plurality of on-board devices are connected to the system. The on-board equipment may be a servo motor, a power distributor, or an explosive device. The servo motor is used to control the movement of mechanical elements to provide power, the distributor is used to generate, store and distribute electrical energy to various devices, and the pyrotechnic product, as a power source, is used in important programs of the aircraft to ensure that each program is important action. [0003] When the system needs to change the motion state of the spaceborne equipment, it generally sends control commands to the corresponding spaceborne equipment through the bus through the management program. The management method of the cu...
