Description
Technical Field
The invention relates to the technical field of control system information query, in particular to a system and a method capable of quickly reading equipment information.
Background
With the continuous development of cloud computing, each large internet operator has more and more requirements on the product configuration and density of a server, and when the requirements on the product configuration and density are too high, a plurality of devices, such as up to four or more power supplies or devices such as hard disks, must exist in one server. Meanwhile, the performance and access timeliness requirements of each large internet operator on server products are higher and higher, for example, for the timeliness problem of all devices in a server accessed by a main control board with a control unit, the function requires that the control unit accesses all device information of the server through an I2C or other buses, including fault information, the conventional design mode is to access all devices through an I2C polling mode, so-called polling is to arrange all devices into a queue, and the control unit accesses the server sequentially from front to back according to the sequence of the queue. When a device behind the queue fails in the polling process, the device also needs to wait for an access command of the control unit to arrive and can send information to the control unit, and this way often results in failure information being not obtained in the first time, and even more, important information is missed. Therefore, for this situation, an interrupt mechanism is generally introduced, each device is configured with an interrupt pin, the interrupt signals of the devices are independent from each other, and the interrupt pins of the control unit are also independent. The control unit connects all devices together via an I2C bus, while keeping the I2C address of each device different. When any one device fails, the device sends a device abnormal interrupt signal to the control unit, when the control unit receives interrupt information corresponding to the interrupt pin, the control unit regards that the device fails, and the control unit accesses the device through the I2C bus to acquire specific fault information. The scheme can quickly acquire specific fault equipment, but the scheme needs to occupy enough interrupt resources, and when the interrupt resources of the control unit are not enough or the enough interrupt resources are not reserved in the reprinting project, the scheme has the defects that the control unit with higher cost is replaced or the project development cycle is prolonged.
In reality, a situation is encountered, and the time urgency requirement of the product development is high for the client. In this case, the development period needs to be shortened by the developers, and at this time, the best way is to reuse the existing product, or to make a partial change development, and make a slight change while ensuring the minimum development workload, which may result in the existing multiplexing part, for example, the main control board with the control unit, not being designed to reserve enough resources to accommodate the additional configuration device in the new requirement. Such as a multiplexed master control board not reserving enough interrupt response pins to handle the newly added device requirements.

Drawings
FIG. 1 is a system diagram of the present invention.
Detailed Description
The invention is further described with reference to the following figures and examples.
When the number of newly added devices exceeds the reserved interrupt response pins in the main control board or the control unit in the main control board does not have enough interrupt response pins, the devices are merged and interrupted, so that a plurality of devices share one interrupt, and when the control unit receives the interrupt information, the control unit can poll the device list corresponding to the interrupt preferentially, thereby achieving the purposes of quickly accessing the devices and saving the interrupt resources of the control unit.
A system capable of quickly reading device information is shown in a system diagram as fig. 1, and the scheme combines polling and interrupt response mechanisms, specifically explaining by taking four devices as an example, device abnormal interrupt signals of a device 1 and a device 2 are respectively connected to a combining unit, the combining unit combines the device abnormal interrupt signals of the two devices into one interrupt signal 1, and device abnormal interrupt signals of a device 3 and a device 4 in the same way are combined into an interrupt signal 2 through the combining unit.
Device 1 and device 2 are connected to I2C of the control unit via the same I2C bus 1, and device 3 and device 4 are connected to I2C of the control unit via the same I2C bus 2. A corresponding table is designed in the control unit, and the table contains the corresponding relation between each interrupt signal and a specific equipment number.
A method for rapidly reading device information adopts a mechanism of first interrupt and then polling, when any device has a fault, for example, when the device 1 has a fault, the device 1 sends a device abnormal interrupt signal to a merging unit, the merging unit outputs the interrupt signal 1 to a control unit, when the control unit receives the interrupt information sent by the interrupt signal 1, a polling mechanism of I2C is started, and the device 1 and the device 2 are polled through an I2C bus 1 to find out a specific fault device.
The invention uses a merging unit to merge the interrupts of a plurality of devices into one interrupt signal, and sends the merged interrupt signal to a control unit. And after the control unit receives the interrupt signal, the control unit quickly responds and starts to poll and search specific equipment in the abnormal area. The control unit is provided with corresponding relation between devices and interrupt signals, and each interrupt signal corresponds to more than one device. The correspondence can assist the control unit to quickly find the abnormal device. The problem of slow access timeliness caused by polling can be solved, and the problems of resource waste and long development period caused by independent interruption of use of all equipment can also be solved.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts by those skilled in the art based on the technical solution of the present invention.
