This not only avoids abnormal operation of equipment due to failure of a single temperature detection device, but also reduces costs by eliminating the need to select a temperature detection device with stronger low-temperature resistance but higher cost.

[0042] For ease of understanding, the specific process in the embodiments of the present application is described below. Figure 1 , Figure 1A schematic flow chart of an embodiment of a line switching method provided in an embodiment of the present application.

[0043] exist Figure 1 In the illustrated embodiment, taking the method applied to an electronic device as an example, the method specifically includes the following steps:

[0044] S101, detecting whether a first operating parameter of a first temperature detection device that currently forms a loop with the control switch is abnormal.

[0045] It should be noted that in the present solution, in order to avoid abnormal operation of the electronic device due to damage of a single temperature detection device, at least two temperature detection devices of the same type are configured in the electronic device, and a control switch is used to control only one of the temperature detection devices to form a loop at a time.

[0046] It should be explained that the first temperature detection device and the second temperature detection device both refer to devices that can be used to detect temperature changes, and the types of the two need to be kept consistent to reduce the error when the method is running. In some embodiments, the first temperature detection device and the second temperature detection device specifically refer to temperature sensors, and the temperature sensors can be specifically divided into thermistors, thermocouples, resistance temperature detectors (RTD, Resistance Temperature Detector), infrared temperature sensors, semiconductor temperature sensors, optical fiber temperature sensors, colorimetric temperature sensors, capacitive temperature sensors and thermistor bridges according to their working principles, which are not limited here. In this embodiment, if the thermistor is used as the first temperature detection device as an example, the first operating parameter corresponding to the first temperature detection device can be the resistance value of the thermistor, or the resistance value of the thermistor can be used as input, and the actual temperature value converted by the resistance value through the digital-to-analog conversion module (AD module) is used as the first operating parameter.

[0047] The control switch refers to a device that can control the on / off of the circuit where the first temperature detection device or the second temperature detection device is located. In this embodiment, since at least two temperature detection devices are limited to form a circuit with only one of the temperature detection devices at a time through the control switch, it is necessary to ensure that the control switch has the above capabilities. Taking the solution composed of the first temperature detection device and the second temperature detection device as an example, the control switch can be a single-pole double-throw switch.

[0048] In some embodiments, the S101 specifically includes the following steps:

[0049] Detecting a first operating parameter of a first temperature detection device currently forming a loop with the control switch;

[0050] If the first operating parameter exceeds a first threshold or is less than a second threshold, determining that the first operating parameter is abnormal, wherein the first threshold is greater than the second threshold;

[0051] If the first operating parameter exceeds the second threshold and is less than or equal to the first threshold, it is determined that the first operating parameter is normal.

[0052] In this embodiment, by detecting the first operating parameter of the first temperature detection device that currently forms a loop with the control switch, taking the resistance value corresponding to the first temperature detection device as an example, when the detection result is that the resistance value exceeds the normally set first threshold value or is less than the second threshold value, it is determined that the resistance value currently measured by the first temperature detection device is abnormal, that is, it indicates that the first temperature detection device may be damaged; correspondingly, when the detection result is that the resistance value exceeds the second threshold value and is less than or equal to the first threshold value, it is determined that the resistance value currently measured by the first temperature detection device is normal, that is, it indicates that the first temperature detection device can be used normally. It should be noted that the first threshold value in the above needs to be greater than the second threshold value.

[0053] S102, if the first operating parameter is abnormal, sending a control instruction to the control switch to control the control switch to disconnect from the first temperature detection device and switch to the second temperature detection device to form a loop.

[0054] In this embodiment, when an abnormality is detected in the first operating parameter corresponding to the first temperature detection device, in order to ensure that the electronic device can continue to operate normally, a control instruction can be sent to the control switch to control the control switch to disconnect from the first temperature detection device, and switch to the second temperature detection device whose default initial state is normal, and connect with it to form a new circuit. Assuming that the second temperature detection device can operate normally, at this time, under the switching action of the control switch, it can replace the abnormally operating first temperature detection device to continue working, avoiding abnormal operation of the equipment due to failure of a single temperature detection device, and there is no need to select a temperature detection device with stronger low temperature resistance but higher cost, thereby reducing costs. At the same time, there is no need to adopt a redundant design of multiple temperature detection devices to jointly detect temperature parameters, thereby reducing the occupation of system resources (such as I / O interfaces) by multiple temperature detection devices.

[0055] In some embodiments, the at least two temperature detection devices are in a state of selective connection or selective short circuit with the control switch under the control of the control switch.

[0056] It should be explained that selective connection refers to a control mechanism in a circuit that allows a specific component or component group in the circuit to be connected to the rest of the circuit, while other components or component groups remain disconnected. Figure 2 As shown, a single-pole double-throw switch is connected to thermistor 1 or thermistor 2, and the single-pole double-throw switch cooperates with a relay, and the working principle of the relay is used to realize the switching of the single-pole double-throw switch. First, thermistor 1 connected to the normally closed contact of the single-pole double-throw switch is operated. When it is detected that thermistor 1 connected to the normally closed contact fails due to abnormal operation, the normally closed contact of the single-pole double-throw switch is controlled to open and the normally open contact is closed by driving the relay, so that thermistor 2 connected to the normally open contact replaces thermistor 1 and continues to work.

[0057] Selective short-circuit refers to the use of a control mechanism to short-circuit a specific component or component group in the circuit while other components or component groups remain in normal working state. Figure 3 As shown, a single-pole double-throw switch is connected to thermistor 1 or thermistor 2, and the single-pole double-throw switch cooperates with a relay, and the working principle of the relay is used to realize the switching of the single-pole double-throw switch. First, the thermistor 2 connected to the normally closed contacts of the single-pole double-throw relay is short-circuited, and the thermistor 1 connected to the normally open contacts of the single-pole double-throw relay is operated. When it is detected that the thermistor 1 connected to the normally open contacts fails due to abnormal operation, the normally closed contacts of the single-pole double-throw switch are controlled to open and the normally open contacts are closed by driving the relay, so that the thermistor 1 connected to the normally open contacts is short-circuited, and the thermistor 2 connected to the normally closed contacts replaces the thermistor 1 to continue to work.

[0058] In some embodiments, Figure 4 As shown, after the control switch is controlled to disconnect the connection with the first temperature detection device and switch to connect with the second temperature detection device to form a loop if the first operating parameter is abnormal, the method further includes:

[0059] detecting whether a second operating parameter of the second temperature detection device is abnormal;

[0060] If the second operating parameter is abnormal, it is determined that all the temperature detection devices or the control switches are damaged.

[0061] In this embodiment, when it is detected that the second operating parameter of the second temperature detection device is still abnormal after the control switch is switched, it can be determined that it may be because all the temperature detection devices are damaged or the control switch is damaged, resulting in the circuit being unable to continue to be used even if the control switch is switched.

[0062] In some embodiments, Figure 5 As shown, when the at least two temperature detection devices are under the control of the control switch, and one of the temperature detection devices is selectively short-circuited with the control switch, if the second operating parameter is abnormal, it is determined that all the temperature detection devices or the control switch are damaged, including:

[0063] Acquire the first operating parameter in an abnormal state, and compare the first operating parameter with the second operating parameter;

[0064] If the first operating parameter is consistent with the second operating parameter, and the first operating parameter or the second operating parameter is a preset multiple of the standard operating parameter under normal conditions, it is determined that the control switch is damaged, resulting in a series circuit being formed between the first temperature detection device and the second temperature detection device, wherein the preset multiple corresponds to the total number of the temperature detection devices.

[0065] In this embodiment, if Figure 3 As shown, when at least two temperature detection devices are under the control of a control switch, and one of the temperature detection devices is selectively short-circuited with the control switch, due to this line connection method, once the control switch is short-circuited, a series circuit will be formed between thermistor 1 and thermistor 2. If the first operating parameter is measured to be consistent with the second operating parameter at this time, and the first operating parameter or the second operating parameter is a preset multiple of the standard operating parameter under normal conditions, it is determined that the control switch is damaged, resulting in a series circuit being formed between the first temperature detection device and the second temperature detection device, wherein the preset multiple corresponds to the total number of temperature detection devices, for example, a multiple of 2 corresponding to two temperature detection devices.

[0066] In some embodiments, when it is determined that the cause of the abnormality of the second operating parameter is that the control switch is short-circuited, causing the measured second operating parameter to be a preset multiple of the standard operating parameter, the abnormal second operating parameter can be automatically divided by the preset multiple to obtain normal operating parameters for use by the electronic device.

[0067] In some embodiments, after comparing the first operating parameter with the second operating parameter, the method further comprises:

[0068] If the first operating parameter is inconsistent with the second operating parameter, and the second operating parameter is abnormal, it is determined that all the temperature detection devices are damaged and the control switch is normal.

[0069] In this embodiment, when it is detected that the first operating parameter is inconsistent with the second operating parameter and the second operating parameter is abnormal, it can be determined that the cause of the abnormality may be that all temperature detection devices are damaged, but the control switch is normal.

[0070] In some embodiments, after determining that all the temperature detection devices or the control switches are damaged if the second operating parameter is abnormal, the method further includes:

[0071] Generate a prompt message including the reason for the abnormality of the second operating parameter to prompt the user.

[0072] In this embodiment, when an abnormal operation of the device is detected, a prompt message containing the cause of the abnormal operation of the second operating parameter can be generated to prompt the user, for example, "the cause of the device abnormality may be damage to thermistor 1" or "the cause of the device abnormality may be damage to the single-pole double-throw switch".

[0073] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0074] In specific implementation, the present application is not limited by the execution order of the various steps described. If no conflict occurs, some steps can be performed in other orders or simultaneously.

[0075] As can be seen from the above, the circuit switching method provided in the embodiment of the present application detects whether the first operating parameter of the first temperature detection device that currently forms a loop with the control switch is abnormal; if the first operating parameter is abnormal, the control switch is controlled to disconnect the connection with the first temperature detection device and switch to the connection with the second temperature detection device to form a loop. Utilizing the circuit switching method provided in the embodiment of the present application, at least two temperature detection devices are controlled by the control switch to form a loop with only one of the temperature detection devices at a time, and when one of the temperature detection devices has an abnormal operation, the control switch is automatically controlled to disconnect the connection with the abnormal temperature detection device and switch to another temperature detection device to form a new loop. This can not only avoid equipment operation abnormality caused by failure of a single temperature detection device, but also reduce costs by not needing to select a temperature detection device with stronger low temperature resistance but higher cost. At the same time, there is no need to adopt a redundant design in which multiple temperature detection devices jointly detect temperature parameters, thereby reducing the occupation of system resources by multiple temperature detection devices.

[0076] An embodiment of the present application further provides a circuit switching device, which can be integrated into an electronic device.

[0080] In some embodiments, the at least two temperature detection devices are under the control of the control switch, and one of the temperature detection devices is selectively connected to or selectively short-circuited with the control switch.

[0081] In some embodiments, the abnormality detection module 31 is used to detect a first operating parameter of a first temperature detection device that currently forms a loop with the control switch; if the first operating parameter exceeds a first threshold or is less than a second threshold, it is determined that the first operating parameter is abnormal, wherein the first threshold is greater than the second threshold; if the first operating parameter exceeds the second threshold and is less than or equal to the first threshold, it is determined that the first operating parameter is normal.

[0082] In some embodiments, the device further includes a determination module for detecting whether a second operating parameter of the second temperature detection device is abnormal; if the second operating parameter is abnormal, it is determined that all the temperature detection devices or the control switches are damaged.

[0083] In some embodiments, the device also includes a comparison module, which is used to obtain the first operating parameter under an abnormal state and compare the first operating parameter with the second operating parameter; if the first operating parameter is consistent with the second operating parameter, and the first operating parameter or the second operating parameter is a preset multiple of the standard operating parameter under a normal state, it is determined that the control switch is damaged, resulting in a series circuit being formed between the first temperature detection device and the second temperature detection device, wherein the preset multiple corresponds to the total number of the temperature detection devices.

[0084] In some embodiments, the determination module is used to determine that all the temperature detection devices are damaged and the control switch is normal if the first operating parameter is inconsistent with the second operating parameter and the second operating parameter is abnormal.

[0085] In some embodiments, the device further comprises a prompt module, configured to generate a prompt message including a reason why the second operating parameter is abnormal to prompt a user.
