Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide a satellite service unit manager, which can overcome the shortcomings of the traditional method of using circuit boards on satellites to realize telemetry acquisition and remote control command distribution, integrate its functions into a chip, and solve satellite telemetry problems. Remote control command distribution and data acquisition occupy more circuit boards. Compared with the weight of the entire satellite cable network of similar satellites, the use of this controller can reduce the weight of the cable network by more than 70%, which solves the technical problem of heavy weight of a single machine, greatly Reduce the weight of the whole star and reduce the cost of satellite launch

Embodiment Construction
[0019] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0020] Such as Figure 1 to Figure 5 As shown, the satellite service unit manager of the present invention includes:
[0021] The pulse extraction module 101 processes the input pulse sequence (CP) by a seven-bit addition counter and a comparator, and extracts the required pulse of the manager;
[0022] The manager's internal command execution module 102 performs serial-to-parallel conversion and decoding on the measurement and control command (CK_ZL), and generates twelve corresponding single-pulse / level commands when the recognition command number is the manager's internal execution command;
[0023] The unit instruction decision module 104 compares the measurement and control instruction (CK_ZL) with the externally set unit address (add[3..0]) after serial-to-parallel conversion, and...

The invention discloses a satellite service unit manager. The satellite service unit manager comprises a pulse extraction module which processes an input pulse sequence through a seven-bit addition counter and a comparator to extract pulse required by the manager, and an inside manager instruction execution module which carries out serial-parallel conversion and decoding on a measurement and control instruction. When the identification instruction number is an internal execution instruction of the manager, a corresponding twelve-channel single pulse / level instruction is generated. According tothe invention, the shortcoming that a traditional method uses a circuit board to realize remote measurement acquisition and remote command distribution on a satellite is overcome; the functions are integrated into one chip; the problem that more circuit boards are occupied for satellite remote measurement and control instruction distribution and data acquisition; the weight of a cable network isreduced by more than 70% by the controller compared with the weight of the entire satellite cable network of a similar satellite; the technical problem of large weight of a single machine is solved; the weight of the whole satellite is greatly reduced; and the launch cost of the satellite is reduced.
Description
technical field [0001] The present invention relates to a manager, in particular to a satellite service unit manager. Background technique [0002] A certain type of satellite implements power supply, distribution, control, and measurement for each stand-alone unit in accordance with the principle of proximity to the south, north, and bilge, and implements the power distribution, control, and measurement of the same stand-alone unit on the same stand-alone module. Traditional satellites complete these functions. Completely using an independent stand-alone unit brings problems such as heavy weight and messy cable network. This type of satellite is facing pressure to reduce weight. It is necessary to increase the functional density of the stand-alone unit, reduce the weight of the cable network, and optimize information flow. According to the demand, a satellite service unit manager was invented, which is used as the host computer of the satellite service unit controller, and ...
