Abstract
The utility model provides a module power supply power-up-and-down-controllable system which mainly solves the problem that failure functional modules of an existing module power supply power-up-and-down-controllable system cannot be isolated and cannot be powered down when degradation working is needed. The module power supply power-up-and-down-controllable system comprises two main control modules which are connected with functional modules through a backplane, and an internal 28V-to-5V module with a control end is arranged in each of the main control modules and the functional modules. The module power supply power-up-and-down-controllable system achieves that system main controllers control power up and down of the functional modules, and accordingly the system has a functional module failure isolable capability and a system degradation reconfigurable capability.
Description
Technical field
But the utility model provides a kind of modular power source power-on and power-off control system, belongs to the embedded computer system designing technique.
Background technology
At traditional embedded computer system, have such problem: catastrophic failure appears in certain functional module can't isolate the time, can affect other functional module work, and then affect computer function; The electric power system power supply capacity work of need to demoting of breaking down, but functional module can't be descended electricity.
Summary of the invention
But the utility model provides a kind of modular power source power-on and power-off control system, has mainly solved existing modular power source power-on and power-off and can control system failure functional module and can't isolate, and needs the degradation operational module can't descend the problem of electricity.
Concrete technical solution of the present utility model is as follows:
But this modular power source power-on and power-off control system, comprise two main control modules, main control module is connected with each functional module respectively by backboard, the 28V that is provided with in described main control module and functional module with control end turns inner 5V module, be provided with control signal OC door in described main control module, the resistance that control signal OC door is pulled down to high-impedance state by being used for of arranging on backboard turns inner 5V module with the 28V of functional module and is connected.
The utility model has the advantage of:
But this modular power source power-on and power-off control system has realized system master device control processed functional module power supply up and down, but makes system possess functional module fault isolating power, system's degradation restructural ability.
Description of drawings
Schematic diagram is controlled in the power-on and power-off of Fig. 1 module.
Embodiment
Below solve accompanying drawing the utility model is described in detail, as shown in Figure 1:
Native system is implemented power-on and power-off by main control module to other functional modules and is controlled.The 28V of each functional module turns inner 5V module with control end, and low level enables 5V output, high level is closed the output of 5V power supply, and control signal is from main control module.The power control signal of main control module slot pulls into low level state under quilt in backboard, automatically enable the inner 5V power supply output of main control module.The power control signal of other module slots is pulled into high-impedance state up and down in backboard, close the output of 5V power supply.Main control module is by OC door out-put supply power-on and power-off control signals (drawing on inside), and two main control module output signals realize line and function by the OC door, namely needs only one of them main control module output low level, and power control signal is just low level.The main control module output low level enables the 5V power supply output of other functional modules, the 5V power supply output that the output high level is closed other functional modules, thereby realizes that other functional modules 28V turns the power-on and power-off control of 5V power supply.
Claims (1)
1. but modular power source power-on and power-off control system, it is characterized in that: comprise two main control modules, main control module is connected with each functional module respectively by backboard, the 28V that is provided with in described main control module and functional module with control end turns inner 5V module, be provided with control signal OC door in described main control module, the resistance that control signal OC door is pulled down to high-impedance state by being used for of arranging on backboard turns inner 5V module with the 28V of functional module and is connected.
