[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In the description of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually a class, and the number of objects is not limited. For example, the first object can be one or more. In addition, in the description of the present application, "and / or" represents at least one of the connected objects, and the character " / " generally represents that the front and back associated objects are in an "or" relationship.

[0027] It should be noted that with the rapid development of big data, artificial intelligence, cloud computing and other fields, the application scenarios and demands of servers are increasing. The performance, computing power and functions of servers are all related to the CPU of the server. Therefore, the load status of the CPU in the server is an important operation and maintenance data for server management.

[0028] For the operation and maintenance engineers at the computer room site, simply and conveniently understanding the CPU load status of each server can provide a reference for judging the operating status of the server in terms of power supply, heat dissipation, etc., as well as on-site maintenance of the server.

[0029] Therefore, in the related technology, a load light is designed on the server to display the CPU load status in real time on the front window mounting ear. The load light can emit different light signals based on the load status of the CPU in the server, so that the operation and maintenance engineers at the computer room site can understand the load status of the CPU in the server simply and conveniently based on the light signals emitted by the load light.

[0030] Generally, the control circuit can control the light signal emitted by the load lamp. However, the conventional control circuit in the related art cannot obtain the actual lighting state of the load lamp.

[0031] When the tester tests the load light, the actual lighting status of the load light can only be determined by the tester's on-site observation. The tester cannot remotely obtain the lighting status of the load light through components such as the baseboard management controller (BMC), and thus cannot remotely obtain the test result of the load light based on whether the actual lighting status of the load light meets expectations. The manpower and time costs required to test the load light are high.

[0032] Furthermore, when the test personnel determine through on-site observation that the actual lighting status of the load lamp is not as expected, the test personnel cannot directly and effectively locate the cause of the abnormality and must go to the computer room to perform unpacking inspection and other operations.

[0033] Combine the following Figure 1-Figure 2 A control circuit of the present invention is described.

[0034] Figure 1 Schematic diagram of the control circuit provided by the present invention. Figure 1 As shown, the control circuit 101 includes: a first controller 102 , a connector 103 and an XNOR gate unit 104 .

[0035] The first end of the first controller 102 is respectively connected to the second controller 106 in the electronic device 105 and the first end of the XOR gate unit 104, the second end of the XOR gate unit 104 is connected to the second end of the connector 103, the third end of the XOR gate unit 104 is connected to the second end of the first controller 102, the third end of the first controller 102 is connected to the third end of the connector 103, the fifth end of the connector 103 is connected to the load light module 107, the load light module 107 includes a plurality of load lights, and the second controller 106 is used to monitor the load state of the target element 108 in the electronic device 105 and obtain the load data of the target element 108.

[0036] The first controller 102 is used to generate a control signal for controlling the load light module 107 corresponding to the load data based on the load data when receiving the load data sent by the second controller 106, and then send the control signal to the load light module 107 through the connector 103, so that the load light module 107 emits light in response to the control signal. The first controller 102 is also used to simulate the data signal output by the load light module 107 based on the load data, and after obtaining the simulated data signal, send the simulated data signal to the XNOR gate unit 104.

[0037] The connector 103 is used to obtain a data signal output by the load lamp module 107 in response to a control signal, and send the data signal to the XNOR gate unit 104 .

[0038] The XNOR gate unit 104 is used to compare the data signal and the analog data signal when receiving the data signal and the analog data signal, and then send an output signal carrying the comparison result to the first controller 102 and / or the second controller 106 .

[0039] The first controller 102 is further configured to determine whether to continue to control the load lamp module 107 based on the output signal when receiving the output signal.

[0040] It should be noted that the control circuit 101 in the embodiment of the present invention is used to control the load light module 107. The load light module 107 is used to indicate the load state of the target element 108 in the electronic device 105. The electronic device 105 may include but is not limited to electronic devices 105 such as computers and servers.

[0041] It is understandable that the target element 108 in the electronic device 105 in the embodiment of the present invention can be determined based on actual needs. For example, the target element 108 can be a central processing unit (CPU) in the electronic device 105. The target element 108 in the electronic device 105 is not specifically limited in the embodiment of the present invention.

[0042] Optionally, the first controller 102 in the control circuit 101 in the embodiment of the present invention may be a controller with strong programmability, flexibility and high integration, such as a complex programmable logic device (CPLD), a field programmable gate array (FPGA) and a system on chip (SoC). The specific type of the first controller 102 is not limited in the embodiment of the present invention.

[0043] The second controller 106 in the electronic device 105 can monitor the load state of the target element 108 in the electronic device 105 and obtain the load data of the target element 108 .

[0044] As an optional embodiment, the second controller 106 is a baseboard management controller, and the baseboard management controller is connected to the first controller 102 via a data bus, and the data bus includes an I2C data bus.

[0045] When the first controller 102 receives the load data sent by the second controller, it can generate a control signal (FM_LOAD_LED signal) for controlling the load light module 107 corresponding to the load data based on the load data.

[0046] When generating the control signal, the first controller 102 may send the control signal to the connector 103 via the third end of the first controller 102 and the third end of the connector 103 .

[0047] When the connector 103 receives the control signal, it can send the control signal to the load lamp module 107 through the fifth end of the connector 103 .

[0048] When receiving the control signal, the load lamp module 107 may respond to the control signal and emit light according to the light-emitting mode corresponding to the control signal.

[0049] When receiving the control signal, the load lamp module 107 may respond to the control signal and output a data signal (LOAD_LED_DOUT signal) corresponding to the control signal.

[0050] The connector 103 can obtain the data signal output by the load lamp module 107 in response to the control signal, and send the data signal to the XNOR gate unit 104 .

[0051] It should be noted that, when the load lamp module 107 includes only one load lamp, the data signal output by the load lamp module 107 in response to the control signal is the data signal output by the control module in the load lamp in response to the control signal.

[0052] In the case that the load lamp module 107 includes a plurality of load lamps, the data signal output by the load lamp module 107 in response to the control signal is the data signal output by the control module in each load lamp in the load lamp module 107 in response to the control signal.

[0053] As an optional embodiment, when the load lamp module 107 includes a plurality of load lamps, the load lamps are connected in series, and the load lamp includes a light emitting module and a control module.

[0054] The connector 103 is used to input the control signal into the control module of the first load lamp in the series, and then obtain the data signal output by the control module of the last load lamp in the series as the data signal output by the load lamp module 107 in response to the control signal.

[0055] When receiving the load data sent by the second controller 106 , the first controller 102 is used to simulate the data signal output by the control module of the last load lamp in the series-connected load lamps based on the load data as the simulated data signal.

[0056] It can be understood that the load lamp in the embodiment of the present invention includes a light-emitting module and a control module. The control module of the load lamp can respond to an input control signal to control the light-emitting module to emit light according to a light-emitting mode corresponding to the control signal.

[0057] Figure 2 FIG. 1 is a schematic diagram of the flow of control signals in the control circuit provided by the present invention. Figure 2 As shown, in the case where the load lamp module 107 includes N load lamps, the fifth end of the connector 103 is connected to the first load lamp in the load lamp module 107 .

[0058] After the connector 103 inputs the control signal into the control module of the first load lamp in the load lamp module 107 , the control signal sequentially flows through the load lamps connected in series in the load lamp module 107 to the control module of the Nth load lamp in the load lamp module 107 .

[0059] The control module of the Nth load lamp in the load lamp module 107 responds to the input control signal and outputs a data signal corresponding to the control signal.

[0060] The sixth end of the connector 103 can be connected to the control module of the Nth load lamp in the load lamp module 107, and the connector 103 can obtain the data signal output by the control module of the Nth load lamp in the load lamp module 107 as the data signal output by the above-mentioned load lamp module 107 in response to the above-mentioned control signal.

[0061] When receiving the load data sent by the second controller, the first controller 102 can simulate the data signal output by the load lamp module 107 based on the load data, obtain the analog data signal (FM_LOAD_LED_DOUT signal), and then send the analog data signal to the XNOR gate unit 104 .

[0062] Correspondingly, in the case that the load lamp module 107 includes only one load lamp, the first controller 102 simulates the data signal output by the load lamp based on the load data as the simulated data signal.

[0063] In the case that the load lamp module 107 includes a plurality of load lamps, the first controller 102 simulates a data signal output by a control module of an Nth load lamp in the load lamp module 107 based on the load data as the simulated data signal.

[0064] After acquiring the analog data signal, the first controller 102 may send the analog data signal to the XNOR gate.

[0065] The data signal output by the load lamp module 107 in response to the control signal is the data signal output by the control module in the load lamp in response to the control signal.

[0066] When receiving the data signal output by the load lamp module 107 in response to the control signal output by the first controller 102 and the analog data signal simulated by the first controller 102 based on the received load data, the XNOR gate can generate an output signal (LOAD_LED_FAULT_N signal) carrying the comparison result of the above data signal and the above analog data signal.

[0067] Table 1 is a functional description table of the output signal (LOAD_LED_FAULT_N signal). As shown in Table 1, in the embodiment of the present invention, "1" and "0" can be used to represent the comparison result of the above-mentioned data signal and the above-mentioned analog data signal. When the above-mentioned output signal carries "1", it indicates that the above-mentioned data signal is the same as the above-mentioned analog data signal, and further, it can be explained that the actual lighting state of the load lamp module 107 is consistent with the expectation, and the load lamp module 107 has no abnormality; when the above-mentioned output signal carries "0", it indicates that the above-mentioned data signal is different from the above-mentioned analog data signal, and further, it can be explained that the actual lighting state of the load lamp module 107 is inconsistent with the expectation, and the load lamp module 107 has an abnormality.

[0068] Table 1 Functional description of output signal (LOAD_LED_FAULT_N signal)

[0069] After the XEN-NOR gate generates an output signal carrying a comparison result between the data signal and the analog data signal, the output signal may be sent to the second controller 106 .

[0070] Based on the above output signal, the second controller 106 can determine whether the actual lighting state of the load light module 107 meets expectations, and further determine that there is no abnormality in the load light module 107. The second controller 106 can also issue an abnormality alarm when it is determined that the actual lighting state of the load light module 107 does not meet expectations. The second controller 106 can also send the above output signal to a remote test terminal so that the tester can remotely monitor the actual lighting state of the load light module 107 and perform remote testing on the load light module 107.

[0071] After the XEN-NOR gate generates an output signal carrying a comparison result between the data signal and the analog data signal, the output signal may be sent to the first controller 102 .

[0072] The first controller 102 may determine whether to continue controlling the load lamp module 107 based on the output signal.

[0073] The control circuit in the embodiment of the present invention includes a first controller, a connector and an XNOR gate unit. After the first controller generates a control signal for controlling the load light module based on the load data sent by the second controller in the electronic device, the first controller sends the control signal to the load light module through the connector. The connector obtains the data signal output by the load light module in response to the control signal, and sends the data signal to the XNOR gate unit. The first controller simulates the data signal output by the load light module based on the load data sent by the second controller. After obtaining the simulated data signal, the simulated data signal is sent to the XNOR gate unit. The XNOR gate unit is used to, upon receiving the data signal and the simulated data signal, The first controller and the second controller can compare the comparison signal, and then send the output signal carrying the comparison result to the first controller and / or the second controller. When the control circuit controls the load light module, the second controller in the electronic device can remotely monitor whether the actual lighting state of the load light module meets expectations. Then, when the load light module is tested, there is no need for the tester to go to the airport site to observe the actual lighting state of the load light module, and the test result of the load light module can be obtained. The manpower cost and time cost required for the load light module test can be reduced, the efficiency of the load light module test can be improved, the actual lighting state of the load light module can be monitored in real time, the potential faults of the load light module can be discovered in time, and the operation stability of the electronic device can be improved.

[0074] like Figure 1 As shown, as an optional embodiment, it also includes: an input-output expander 109.

[0075] The first controller 102 and the second controller 106 are both connected to the first end of the XNOR gate unit 104 through the input-output expander 109 .

[0076] It should be noted that the input / output expander 109, referred to as an IO expander, is a hardware device or chip used to increase the number or function of the I / O interfaces of a microcontroller, computer or other computing device. These expanders usually communicate with the main controller through a bus (such as I2C, SPI, UART, etc.) and allow the main controller to control more peripherals or read data from more external devices.

[0077] Optionally, the model of the input / output expander 109 in the embodiment of the present invention may be CA9555.

[0078] As an optional embodiment, the first end of the connector 103 is used to input a standby voltage signal, and the fourth end of the connector 103 is used to be grounded.

[0079] It should be noted that the standby voltage (P5V_STBY) signal represents a voltage signal that maintains power supply when the motherboard is in standby mode. The standby voltage signal is an important signal in the power management system of the electronic device 105, which is used to provide standby voltage support for key parts of the system and plays an important role in the power-on sequence of the system.

[0080] The first controller 102 may determine whether the electronic device 105 is powered on based on the input standby voltage signal received by the connector 103 .

[0081] As an optional embodiment, the third end of the first controller 102 is used to input a first input signal indicating whether the electronic device 105 has successfully loaded and run the operating system, and the fourth end of the first controller 102 is used to input a second input signal indicating the operating status of the electronic device 105.

[0082] It should be noted that, when the first input signal (80 port signal) input to the first controller 102 does not carry "0x04", it means that the electronic device 105 has not successfully loaded and run the operating system; when the first input signal (80 port signal) input to the first controller 102 carries "0x04", it means that the electronic device 105 has successfully loaded and run the operating system.

[0083] The first controller 102 may determine whether the electronic device 105 has successfully loaded and executed the operating system based on the input first input signal.

[0084] It should be noted that, when the second input signal (SLP4 signal) input to the first controller 102 carries "1", it indicates that the electronic device 105 is in the power-on state; when the second input signal (SLP4 signal) input to the first controller 102 carries "0", it indicates that the electronic device 105 is in the standby state.

[0091] It should be noted that the code of the first controller 102 in the embodiment of the present invention includes a status register, and the value of the status register in the first controller 102 represents the control signal sent to the load lamp module 107 .

[0092] It should be noted that, in the embodiment of the present invention, the corresponding relationship between the value of the status register in the first controller 102 and the control signal and the corresponding relationship between the value and the operating state of the electronic device 105 can be determined based on existing knowledge and / or actual conditions.

[0096] Table 3 Functional description of the values ​​of the first to third bits of the status register in the first controller

[0097] Among them, each lighting mode in the embodiment of the present invention can be determined based on prior knowledge and / or actual conditions. For example, the first lighting mode includes a green marquee; the second lighting mode includes a green constant light; the third lighting mode includes a green constant light; the fourth lighting mode includes a blue constant light; the fifth lighting mode includes a yellow constant light; green indicates a light load, blue indicates a medium load, and yellow indicates a high load. In the embodiment of the present invention, no specific limitation is made to each lighting mode.

[0098] The control circuit in the embodiment of the present invention controls the load light module based on the operating status of the electronic device and whether the operating system is successfully loaded and run. When it is determined that the electronic device is in the turned-on state and the operating system is successfully loaded and run, the load light module can be controlled based on the received load data, thereby further improving the reliability and flexibility of controlling the load light module.

[0099] As an optional embodiment, the XNOR gate unit 104 is used to send the output signal to the first controller 102 and the second controller 106 .

[0100] The first controller 102 is also used to send the value of the status register to the second controller 106, so that the second controller 106 can determine whether there is an abnormality in the control of the load light module 107 based on the output signal and the value of the status register, and obtain the cause of the abnormality in the control of the load light module 107 when it is determined that there is an abnormality in the control of the load light module 107.

[0101] Specifically, the first controller 102 may send the updated value of the status register to the second controller 106 after updating the value of the status register each time.

[0102] When the second controller 106 receives the output signal sent by the XNOR gate unit 104 and carrying the comparison result of the data signal and the analog data signal, it can determine whether there is any abnormality in the control of the load light module 107 based on the above output signal and the value of the status register of the first controller 102 received most recently, and when it is determined that there is any abnormality in the control of the load light module 107, obtain the cause of the abnormality in the control of the load light module 107.

Table 4 shows the correspondence between the values ​​carried by the output signal and the values ​​of the status register in the first controller 102 and the causes of the abnormality of the load lamp module 107.

[0104] Table 4 Correspondence between the value carried by the output signal (LOAD_LED_FAULT_N signal), the value of the status register in the first controller, and the cause of the abnormality of the load lamp module 107

[0105] It should be noted that "X" in Table 4 represents "0" or "1". The corresponding relationship between the value carried by the output signal (LOAD_LED_FAULT_N signal) shown in Table 4 and the value of the status register of the first controller 102 and the cause of the abnormality of the load lamp module 107 is determined based on the functional description of the value of the status register in the first controller 102 shown in Tables 2 and 3.

[0106] It can be understood that the combination of the value carried by the output signal and the value of the state register of the first controller 102 is not in the combination shown in Table 4, indicating that the load lamp module 107 is not abnormal.

[0107] The control circuit in the embodiment of the present invention sends the output signal to the first controller and the second controller through the XNOR gate unit, and the first controller sends the value of the status register to the second controller, so that the second controller can determine whether there is an abnormality in the control of the load light module based on the output signal and the value of the status register, and when it is determined that there is an abnormality in the control of the load light module, obtain the cause of the abnormality in the control of the load light module, and can locate the cause of the abnormality more efficiently and accurately, which can further improve the testing efficiency of the load light module and the maintenance efficiency of the load light module.

[0108] Figure 3 FIG. 1 is one of the flow charts of the load lamp control method provided by the present invention. The load lamp control method provided by the present invention is implemented based on the control circuit 101 as above. Figure 3 As shown, the method includes the following: step 301, when receiving load data sent by the second controller 106 in the electronic device 105, based on the load data, a control signal for controlling the load light module 107 corresponding to the load data is generated, and the data signal output by the load light module 107 in response to the control signal is simulated to obtain a simulated data signal. The second controller 106 is used to monitor the load state of the target element 108 in the electronic device 105 and obtain the load data of the target element 108.

[0109] Step 302: Send the control signal to the load light module 107, so that the load light module 107 emits light in response to the control signal.

[0110] Step 303: Acquire the data signal output by the load lamp module 107 in response to the control signal.

[0111] Step 304 : compare the data signal and the analog data signal, send an output signal carrying the comparison result to the second controller 106 , and / or continue to control the load lamp module 107 .

[0112] It should be noted that the execution subject of the embodiment of the present invention is the control circuit 101 mentioned above.

[0113] It should be noted that, since the load lamp control method provided by the present invention is implemented based on the above control circuit 101, the specific execution steps of the load lamp control method can refer to the contents of the above embodiments, which will not be described in detail in the embodiments of the present invention.

[0114] In the embodiment of the present invention, when receiving load data sent by a second controller in the electronic device, based on the load data, a control signal of the load light module and a data signal output by the simulated load light module are generated to obtain a simulated data signal. The second controller is used to monitor the load state of a target element in the electronic device, obtain the load data of the target element, send the control signal to the load light module so that the load light module emits light in response to the control signal, obtain the data signal output by the load light module in response to the control signal, compare the data signal with the simulated data signal, send the output signal carrying the comparison result to the second controller, and / or continue to control the load light module, so that the second controller in the electronic device can remotely monitor whether the actual lighting state of the load light module meets expectations. When testing the load light module, there is no need for the tester to go to the airport site to observe the actual lighting state of the load light module, and the test result of the load light module can be obtained, which can reduce the manpower cost and time cost required for the load light module test, improve the efficiency of the load light module test, monitor the actual lighting state of the load light module in real time, and timely discover the potential faults of the load light module, thereby improving the operation stability of the electronic device.

[0115] As an optional embodiment, when load data sent by the second controller 106 in the electronic device 105 is received, a control signal for controlling the load light module 107 corresponding to the load data is generated based on the load data, and the data signal output by the load light module 107 in response to the control signal is simulated. Before obtaining the simulated data signal, the method also includes: when it is determined that the electronic device 105 is powered on, a first control signal for controlling the load light module 107 not to emit light is generated, and the data signal output by the load light module 107 in response to the first control signal is simulated to obtain a first simulated data signal, and then the first control signal is sent to the load light module 107, and the value of the status register is updated to the first numerical value.

[0116] Obtain the first data signal output by the load lamp module 107 in response to the first control signal, compare the first data signal with the first analog data signal, and determine whether the electronic device 105 is in the power-on state when it is determined that the first data signal and the first analog data signal are consistent and the value of the status register is the first value.

[0117] When it is determined that the electronic device 105 is in the power-on state, a second control signal is generated to control the load lamp module 107 to emit light in a first light-emitting mode, and the data signal output by the simulated load lamp module 107 in response to the second control signal is obtained to obtain a second simulated data signal, and then the second control signal is sent to the load lamp module 107, and the value of the status register is updated to a second value.

[0118] Obtain the second data signal output by the load light module 107 in response to the second control signal, compare the second data signal with the second analog data signal, and determine whether the electronic device 105 has successfully loaded and run the operating system when it is determined that the second data signal and the second analog data signal are consistent.

[0119] When it is determined that the electronic device 105 has successfully loaded and run the operating system, a third control signal is generated to control the load light module 107 to emit light in a second light-emitting mode, and the data signal output by the simulated load light module 107 in response to the third control signal is obtained to obtain a third simulated data signal, and then the third control signal is sent to the load light module 107, and the value of the status register is updated to a third numerical value.

[0120] Obtain the third data signal output by the load lamp module 107 in response to the third control signal, compare the third data signal with the third analog data signal, and when it is determined that the third data signal and the third analog data signal are consistent, if the load data is sent by the second controller 106, generate a control signal corresponding to the load data based on the load data.

[0121] Figure 4 This is the second flow chart of the load lamp control method provided by the present invention. Figure 4 Table 2 and Table 3 illustrate the load lamp control method in the embodiment of the present invention.

[0122] When determining that the electronic device 105 is powered on, the first controller 102 generates a first control signal (FM_LOAD_LED signal) for controlling the load light module 107 not to emit light, and then sends the first control signal to the load light module 107 through the connector 103, and updates the value of the status register to the first value ("0000").

[0123] The XNOR gate unit 104 obtains the first data signal output by the load lamp module 107 in response to the first control signal, compares the first data signal with the first analog data signal, and sends an output signal (LOAD_LED_FAULT_N signal) carrying the comparison result to the first controller 102 .

[0124] When the first controller 102 determines that the value carried by the output signal (LOAD_LED_FAULT_N signal) is "1" and the value of the status register is the first value ("0000"), the first controller 102 determines whether the electronic device 105 is in the power-on state based on the received second input signal.

[0125] When the first controller 102 receives the second input signal (SLP4 signal) carrying "0", it indicates that the electronic device 105 is in standby mode. The first controller 102 continues to send the first control signal to the load lamp module 107 and maintains the value of the status register as the first value ("0000").

[0126] When the first controller 102 receives a second input signal (SLP4 signal) carrying "1", indicating that the electronic device 105 is in the power-on state, the first controller 102 generates a second control signal (FM_LOAD_LED signal) for controlling the load light module 107 to emit light in the first light-emitting mode, simulates the data signal output by the load light module 107 in response to the second control signal, obtains a second analog data signal, and then sends the second control signal to the load light module 107, and updates the value of the status register to the second numerical value ("1010").

[0127] The XNOR gate unit 104 obtains the second data signal output by the load lamp module 107 in response to the second control signal, compares the second data signal with the second analog data signal, and sends an output signal (LOAD_LED_FAULT_N signal) carrying the comparison result to the first controller 102 .

[0128] When the first controller 102 determines that the value carried by the output signal (LOAD_LED_FAULT_N signal) is “1”, the first controller 102 determines whether the electronic device 105 has successfully loaded and run the operating system based on whether the first input signal is received.

[0129] When the first controller 102 does not receive the first input signal (80 port signal) carrying "0x04" or the second input signal (SLP4 signal) carrying "1", it indicates that the electronic device 105 has not successfully loaded and run the operating system or is in standby mode, and the first controller 102 returns to determine whether the second input signal (SLP4 signal) carrying "1" is received.

[0130] When the first controller 102 receives a first input signal (80 port signal) carrying "0x04" and a second input signal (SLP4 signal) carrying "1", it indicates that the electronic device 105 has successfully loaded and run the operating system, and the first controller 102 generates a third control signal for controlling the load light module 107 to emit light in a second light-emitting mode, simulates the data signal output by the load light module 107 in response to the third control signal, obtains a third simulated data signal, and then sends the third control signal to the load light module 107, and updates the value of the status register to a third numerical value ("1100").

[0131] The XNOR gate unit 104 obtains the third data signal output by the load lamp module 107 in response to the third control signal, compares the third data signal with the third analog data signal, and sends an output signal (LOAD_LED_FAULT_N signal) carrying the comparison result to the first controller 102 .

[0132] When the first controller 102 determines that the value carried by the output signal (LOAD_LED_FAULT_N signal) is "1", if the second controller 106 sends load data, it generates a control signal corresponding to the load data based on the load data, simulates the data signal output by the load lamp module 107 in response to the above control signal, obtains the analog data signal corresponding to the above load data, and then sends the above control signal to the load lamp module 107, and updates the value of the status register to the value corresponding to the above control signal.

[0133] The XNOR gate unit 104 obtains the data signal output by the load lamp module 107 in response to the control signal corresponding to the load data, compares the control signal corresponding to the load data with the analog data signal corresponding to the load data, and sends an output signal (LOAD_LED_FAULT_N signal) carrying the comparison result to the first controller 102 .

[0134] When the first controller 102 determines that the value carried by the output signal (LOAD_LED_FAULT_N signal) is “1” and the value of the status register is “11XX”, the first controller 102 determines that the second input signal (SLP4 signal) carrying “0” is received.

[0135] When the first controller 102 does not receive the second input signal (SLP4 signal) carrying “0”, the first controller 102 continues to control the load lamp module 107 based on the load data sent by the second controller 106 .

[0136] When the first controller 102 receives the second input signal (SLP4 signal) carrying “0”, it ends controlling the load lamp module 107 .

[0137] The XNOR gate unit 104 can send each generated output signal (LOAD_LED_FAULT_N signal) to the second controller 106. Accordingly, after each update of the value of the status register, the first controller 102 sends the updated value of the status register to the second controller 106, so as to determine whether the control of the load light module 107 is abnormal based on the output signal (LOAD_LED_FAULT_N signal) and the value of the status register, and obtain the cause of the abnormal control of the load light module 107 when it is determined that the control of the load light module 107 is abnormal.

[0138] The first controller 102 may also send the output signal (LOAD_LED_FAULT_N signal) carrying the value "0" and the current value of the first controller 102 status register to the second controller 106 when determining that the output signal (LOAD_LED_FAULT_N signal) carries the value "0", so that the second controller 106 can record the output signal (LOAD_LED_FAULT_N signal) carrying the value "0" and the current value of the first controller 102 status register, and obtain the cause of the abnormal control of the load lamp module 107 based on the output signal (LOAD_LED_FAULT_N signal) carrying the value "0" and the current value of the first controller 102 status register.
