All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In the prior art, when a fault existing in hardware is identified, a conventional instrument is usually adopted to measure surface layer data of a hardware circuit board, such as a current value, a voltage value and the like in the circuit board, but a relatively complex problem existing in the hardware cannot be determined through the surface layer data, so that the hardware fault is difficult to accurately identify through data detected by the conventional instrument.
The embodiment of the invention provides a method for acquiring hardware running state data, which is applied to hardware detection equipment and comprises the following steps as shown in figure 1:
step S10: and detecting a connection event, and determining a connection interface connected with the equipment to be detected according to the connection event. In an optional embodiment, the to-be-detected device may be a CPU, a ROM, or the like of the motherboard, and if the to-be-detected motherboard is a network device, the to-be-detected device may be a network interface, a communication module, or the like of the to-be-detected motherboard.
When the hardware detection equipment is connected with the equipment to be detected, the hardware detection equipment and the equipment to be detected can detect a connection event. The hardware detection equipment and the equipment to be detected can be connected through different interfaces, such as a USB interface, a serial port, an Ethernet interface, a contact pin, a flat cable and the like, and for different connection interfaces, the communication connection with the equipment to be detected needs to be established in different modes.
After the connection event is detected, it is necessary to determine whether the connection interface connected to the device to be detected is a general interface, and in an optional embodiment, a system of the device to be detected may be defaulted to include general drivers for the common interfaces such as a USB interface, a serial interface, an ethernet interface, and the like, so that the common interfaces such as the USB interface, the serial interface, the ethernet interface, and the like may be determined to be the general interface.
The embodiment of the invention provides two methods for establishing communication connection with equipment to be detected, wherein the first method is to execute the step S21-the step S22, and the second method is to execute the step S23, and when a connection interface connected with the equipment to be detected is a universal interface, the communication connection with the equipment to be detected can be established by executing any one method.
The method comprises the following steps:
step S21: and setting the characteristic value representing the connection attribute as a preset value by using a preset identification code segment, and when the characteristic value representing the connection attribute is the preset value, indicating that the connection attribute is the slave equipment.
After the hardware detection device is connected with the device to be detected through the interface, the device to be detected and the hardware detection device can both recognize the connection event of each other. However, for two conventional devices with systems, after connecting with another device, the connection attribute of the device is set as a host/server by default, and when both devices have device drivers for the same interface, the connection attribute of the devices that are both host devices cannot be recognized after the devices are connected to each other, so that communication connection cannot be established.
In the embodiment of the invention, the hardware detection equipment is defined with the equipment drivers corresponding to the connection interfaces, the equipment to be detected is defaulted to contain the equipment drivers corresponding to the universal interfaces, and when the interface connected with the equipment to be detected is detected to be the universal interface, in order to avoid that two main devices cannot establish communication connection, the connection attribute of the hardware detection equipment is set as slave device (slave/client), so that the equipment to be detected can actively identify the connection attribute of the hardware detection equipment, and the communication connection between the hardware detection equipment and the equipment to be detected is realized.
Step S22: and establishing communication connection with the equipment to be detected through an equipment driver corresponding to the connection interface in the equipment to be detected. In the embodiment of the invention, the communication connection is established between the equipment driver corresponding to the connection interface in the equipment to be detected and the equipment to be detected, which means that the hardware detection equipment is identified and authorized by the equipment to be detected through the equipment driver corresponding to the connection interface in the equipment to be detected.
In an optional embodiment, step S21 specifically includes:
the method comprises the steps that a preset identification code segment is utilized to control hardware detection equipment to request host role negotiation protocol (HNP) service to equipment to be detected, when the hardware detection equipment requests the HNP service to the equipment to be detected, the positive electrode level of a signal line of the hardware detection equipment is prohibited to be pulled up, and a hardware detection equipment bus enters an idle state (SE 0 state) at a high speed;
the method comprises the steps that a hardware detection device detects the bus state of a device to be detected, when the bus state of the device to be detected is an idle state (J state) at full speed, the level of a pin used for representing the connection attribute of the hardware detection device is converted from a low level to a high level, and the connection attribute is converted from a master device to a slave device; in an optional embodiment, when the device to be detected detects that the bus state of the hardware detection device is the SE0 state, the bus state of the device to be detected is modified into the J state, and the HNP service initiated by the hardware detection device is responded;
and releasing the pull-up prohibition of the positive level of the signal wire, and recovering communication, wherein at the moment, the hardware detection equipment can receive the drive of the equipment to be detected by the identity of the slave equipment, so that the connection between the hardware detection equipment and the equipment to be detected is realized.
In the process, the connection attribute of the hardware detection equipment can be converted without executing any operation on the equipment to be detected, the communication connection between the hardware detection equipment and the equipment to be detected is realized, and the process of establishing the communication connection is simple.
In an optional embodiment, when the hardware detection device is connected with the device to be detected through a USB interface, the preset identification code segment controls the hardware detection device to request HNP service from the device to be detected, in this process, the hardware detection device prohibits the USBD + (positive electrode of the USB signal line) level from being pulled up, so that the bus of the hardware detection device enters an SE0 state, then the bus state of the device to be detected is detected, if the bus state of the device to be detected is a J state, the level of a pin for representing the connection attribute of the device is converted from a low level to a high level, the connection attribute is converted from the master device to the slave device, then the pull-up prohibition of the D + is removed, and communication is resumed.
In an optional embodiment, if the connection interface is a USB interface, the preset identification code segment may be an stty instruction, that is, the hardware detection device modifies the connection attribute using the stty instruction, and then checks all file system and hardware information of the device to be detected using a cat or ls manner. This process can be achieved without the confirmation of the device to be detected.
In the method provided by the embodiment of the invention, if the connection interface of the hardware detection device and the equipment to be detected is a universal interface, the connection attribute of the hardware detection device is modified into slave equipment, and the communication connection between the hardware detection device and the equipment to be detected is established through the equipment driver corresponding to the connection interface in the equipment to be detected. When the equipment driver corresponding to the connection interface exists in the equipment to be detected, the communication connection between the hardware detection equipment and the equipment to be detected can be established on the basis of not performing any operation on the equipment to be detected and not influencing the normal work of the equipment to be detected by implementing the embodiment of the invention even if the equipment driver corresponding to the connection interface exists in the hardware detection equipment and the equipment to be detected at the same time, so that the plug-and-play of the hardware detection equipment is realized, and the hardware running state data of the equipment to be detected can be quickly acquired.
The second method comprises the following steps:
step S23: logging in a server system of the equipment to be detected, and establishing communication connection with the equipment to be detected.
When both devices have device drivers for the same connection interface, in order to solve the problem that the two devices, which are both master devices, cannot identify the connection attributes of each other after being connected to each other, and thus cannot establish communication connection, unlike the above-mentioned step S21-step S22, in the embodiment of the present invention, the communication connection between the hardware detection device and the device to be detected is established in a manner of logging the hardware detection device into the system of the device to be detected in a client manner.
In an optional embodiment, if the connection interface is a serial port, the serial port can be controlled by a screen instruction to log in a system of the device to be detected in a client mode. All file system and hardware information of the device to be tested is then checked using cat or ls. This process can be achieved without the confirmation of the device to be detected.
In an optional embodiment, if the connection interface is an ethernet interface, protocols such as telnet and ssh may be used, so that the hardware detection device logs in the server system of the device to be detected in a client mode. The conventional login mode needs to frequently input login passwords, and the login automation can be realized by adopting an expect function automatic password input method and a ssh-copy-id password-free login method in the embodiment of the invention. After the login is completed, the hardware detection device serves as a client and can send a detection instruction to the device to be detected, and the device to be detected can return a detection result according to the detection instruction.
In the embodiment of the invention, in order to acquire deeper data and information related to hardware, the hardware detection equipment is controlled to establish communication connection with the equipment to be detected, the deeper data can be acquired only by establishing the communication connection with the equipment to be detected, and only the surface layer data of the hardware circuit board can be acquired if simple physical connection is established.
Step S30: and acquiring hardware running state data of the equipment to be detected.
In an optional embodiment, the acquired hardware operation state data of the device to be detected includes one or more items of a use condition, an operating temperature, an operating voltage, an operating current, and the like of the device to be detected.
The obtained hardware running state data are different for different devices to be detected, and exemplarily, if the devices to be detected are a CPU and an RAM, the hardware running state data include CPU usage, CPU occupancy, CPU temperature, CPU power consumption, RAM usage, RAM occupancy, RAM temperature, RAM power consumption and the like;
if the equipment to be detected is a network interface and a communication module, the hardware running state data comprises: network interface on-off condition, network interface rate, expansion module connection condition and the like;
and if the device to be detected is a CPU with multi-core/multi-thread performance, the hardware running state data comprises the running data of each core/thread.
When the method for acquiring the hardware running state data provided by the embodiment of the invention is applied to hardware detection equipment, a connection event is detected firstly, a connection interface connected with the equipment to be detected is determined, then communication connection is established with the equipment to be detected according to a connection mode corresponding to the connection interface, and finally the hardware running state data of the equipment to be detected is acquired.
In an optional embodiment, as shown in fig. 1, if the connection interface connected to the device to be detected is a custom interface, the following steps are performed:
step S24: and establishing communication connection with the equipment to be detected through the equipment driver corresponding to the connection interface.
The self-defined interface is self-defined in the hardware detection equipment, the equipment to be detected does not have corresponding equipment drive, and the equipment to be detected cannot finish active identification on the hardware detection equipment, so the hardware detection equipment can drive the equipment to be detected as slave equipment (slave) by using the role of main equipment (host).
In an optional embodiment, when the hardware detection device is connected with the device to be detected by means of pins and cables, the connection interface may be determined as a custom interface.
In an optional embodiment, one or more custom interfaces and device drivers corresponding to the respective defined interfaces may be predefined in the hardware detection device, and for the device driver corresponding to each custom interface, a software module is defined, where the software module includes an h file and an c file, where the h file defines a data structure of the device driver, and declares an external function, and the c file implements the specific implementation of the device driver. And the software module can directly access the interface of the equipment driver without crossing any layer and directly read the data of the equipment to be detected from the equipment interface.
According to the method provided by the embodiment of the invention, when the hardware detection equipment is connected with the equipment to be detected through the custom interface in the hardware detection equipment, the communication connection between the hardware detection equipment and the equipment to be detected is established through the equipment driver corresponding to the connection interface in the hardware detection equipment.
The two different methods for establishing communication connection provided in steps S21-S22 and S23 are both based on the premise that the device driver corresponding to the connection interface exists in the device under test, and if the two methods are executed, the connection between the hardware testing device and the device under test fails, it is considered that it may be caused by the absence of the device driver corresponding to the connection interface in the device to be inspected, and therefore, in an alternative embodiment, after the above steps S21-S22 and/or S23 are performed, if the connection between the hardware testing device and the device to be tested fails, the characteristic value characterizing the connection attribute in the hardware detection device may be modified, so that the connection attribute of the hardware detection device is the master device, and establishing communication connection between the hardware detection equipment and the equipment to be detected through equipment drivers corresponding to the connection interfaces in the hardware detection equipment.
The method for establishing communication connection provided in step S24 is based on the premise that the device driver corresponding to the connection interface does not exist in the device to be detected, and after step S24 is executed, if the connection between the hardware detection device and the device to be detected fails, it is considered that the connection may be caused by the device driver corresponding to the connection interface existing in the device to be detected, so in an optional embodiment, after step S24 is executed, if the connection between the hardware detection device and the device to be detected fails, step S21-step S22 may be executed, or step S23 is executed to establish communication connection between the hardware detection device and the device to be detected.
