Embodiment 1

[0033] The modularized equipment inspection and maintenance device provided by Embodiment 1 of the present invention has a structure as follows: figure 1 As shown, including: FPGA unit and module isolation unit. The control, detection and fault recovery settings of the modules in the modular equipment are realized through the FPGA unit and the module isolation unit.

[0034] The FPGA unit is used to control the start-up of each module in the modular equipment according to the set control logic; for the current start-up module being started, control the input state of the current start-up module, and detect whether the output state of the current start-up module is normal; if normal, Then continue to start the next-level module; if it is not normal, control the module isolation unit connected to the current startup module to isolate the current startup module, and set the current startup module so that the output state is normal. After the control module isolation unit release...

Embodiment 2

[0066] The modular equipment detection and maintenance device provided in Embodiment 2 of the present invention is different from the modular equipment detection and maintenance device provided in Embodiment 1 in that the device controls, detects and and the different needs of the settings, in figure 1 On the basis of the modular equipment detection and maintenance device shown, one or a combination of the following modules is set between the FPGA unit and the modules in the modular equipment: a module control unit, a module detection unit and a module setting unit. Specifically, when the control of the FPGA unit to the module requires the cooperation of an external control unit, the module control unit is set; when the detection of the FPGA unit to the module requires the cooperation of an external detection unit, the module detection unit is set; When the setting requires the cooperation of an external control unit to be realized, set the module to set the unit. The struct...

Embodiment 3

[0078] The third embodiment of the present invention specifically describes the specific implementation process of detecting the power module in the modularized device and recovering the device from a fault.

[0079] Modular devices, such as router hosts, generally have strict requirements on the power-on time of power modules. Various power modules must be powered on in a set order, otherwise the modular devices will not be able to be configured normally and malfunction. For example: first, power on the power supply module at 1.2V to precharge the CPU and other components, and then power on at 5V to power the CPU.

[0080] Currently, when realizing the above-mentioned power supply sequence control, the following methods are generally adopted: Figure 7 The enable circuit shown in the figure realizes the control, through the 1.2V VDD input (VDD1V2 shown in the figure), the 5V enable output (5V_EN shown in the figure) is obtained to control the power supply module.

[0081] An...

Abstract

The invention discloses a method and a device for detecting and maintaining modular equipment, and modular equipment. The method comprises the following steps of: arranging a field programmable gate array (FPGA) unit used for controlling startup of various modules in the modular equipment according to the set control logic, and a module isolating unit; and controlling an input state of a current started module, and detecting whether the output state of the current started module is normal, if so, continuously starting the next module, otherwise, controlling the module isolating unit which is connected with the current started module to isolate the current started module, and setting the current started module so as to control the module isolating unit to release isolation from the currentstarted module and continuously start the next module after the output state is normal. Therefore, the module failure in the modular equipment can be timely detected and recovered so as to avoid influencing the complete machine.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a modular equipment detection and maintenance method, device and modular equipment. Background technique [0002] With the development of communication technology, modular equipment composed of multiple independent functional modules has been more and more widely used. Each functional module in the modular equipment is responsible for completing part of the functions of the whole machine, and each functional module coordinates to work together to achieve The functions to be realized by the whole machine. [0003] The modules of the modular equipment both influence and restrict each other. Once one or several functional modules fail, it will affect the normal operation of other modules. Moreover, each functional module cannot realize the normal recovery of the hardware configuration, resulting in the failure of the modular equipment to recover as soon as possible, resultin...
