BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings:

[0027] Figure 1 This is a schematic diagram of the electrical system of a common travel switch for satellite autonomous power-on and software self-startup according to an embodiment of the present invention. DETAILED DESCRIPTION

[0028] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0029] Example 1

[0030] like Figure 1 , which is a connection relationship diagram of the shared travel switch for autonomous power-on and software self-start in an embodiment of the present invention. The present invention provides a control method for the shared travel switch for autonomous power-on and software self-start. Through the shared circuit design of the satellite-rocket separation travel switch, the autonomy and reliability of the satellite in the critical stage are effectively improved.

[0031] The specific steps include:

[0032] Step S1: Use a travel switch to power on the satellite, which is located at both ends of the power-on control signal of the power controller and the integrated electronic computer software program-controlled start signal;

[0033] Step S2: The contacts connected between the two ends of the power control signal on the power controller are connected in parallel, and the contacts connected between the two ends of the integrated electronic computer software program-controlled start signal are connected in series;

[0034] The travel switch comprises two pairs of contacts, such as Figure 1 As shown, Ka1 and Kb1 are two pairs of contacts of the same travel switch, which are used to connect the two ends of the power-on control signal of the power controller and the two ends of the software program-controlled start signal of the integrated subcomputer. The same is true for Ka2 and Kb2 to Kan and Kbn.

[0035] In step S1, the software program-controlled start signal of the integrated electronic computer is realized by connecting multiple travel switches from Kb2 to Kbn in series to prevent the software program-controlled start from being triggered by the erroneous release of a single travel switch.

[0036] In step S2, the self-power-on control signal of the power controller is realized by connecting multiple travel switches Ka1 and Kb1 in parallel to ensure that the release of any travel switch can lead to autonomous power-on of the satellite.

[0037] When a single travel switch fails after the separation of the satellite and the rocket, the parallel connection of Ka1 and Kb1 enables the satellite to be powered on normally and complete the software-controlled startup by receiving the program-controlled startup instructions from the ground.

[0038] When a single travel switch is mistakenly released in the active segment of the satellite, the series connection from Kb2 to Kbn can ensure that the satellite software program control is not started, thus ensuring the energy safety of the satellite.

[0039] The travel switch model is 2KX-1, and the travel switch is configured at the separation interface between the satellite and the launch vehicle so as to activate the travel switch when the satellite and the rocket are separated.

[0040] The travel switch control method is used to achieve autonomous power-on and software self-start after the separation of the satellite and the rocket.

[0041] The travel switch is designed to work stably in extreme environments, including high temperature, low temperature, high pressure, low pressure, strong vibration and vacuum environment.

[0042] The present invention also provides a computer-readable storage medium storing a computer program, and when the computer program is executed by a processor, the steps of the control method of the common travel switch are implemented.

[0043] The present invention also provides an electronic device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the computer program implements the steps of the control method of the common travel switch when executed by the processor.

The travel switch includes two pairs of contacts, which are respectively connected between the two ends of the power-on control signal of the power controller and the two ends of the integrated electronic computer software program-controlled start signal.

[0047] The integrated electronic computer software program-controlled start signal is realized by connecting a plurality of travel switches in series.

[0048] The power-on control signal of the power controller is realized by connecting a plurality of travel switches in parallel.

[0049] The travel switches are arranged at the separation interface between the satellite and the launch vehicle, are evenly arranged on the outer edge of the satellite-rocket separation surface, and every two travel switches are at least 50 mm apart.
