[0002] A load lamp is a type of light fixture used to indicate the load status of electronic equipment. Load lamps are of great significance for indicating the load status of electronic equipment, protecting electronic equipment, and assisting in diagnosis.

[0003] In related technologies, when testers test load lamps, the actual lighting status of the load lamps can only be determined by the testers' on-site observation. Testers cannot remotely obtain the lighting status of the load lamps, which means that testers cannot remotely complete the test of the load lamps based on whether the actual lighting status of the load lamps meets expectations. The manpower and time costs required to test load lamps are relatively high.

[0004] Therefore, how to remotely obtain the actual lighting status of the load lamp, thereby improving the testing efficiency and operational reliability of the load lamp, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0016] According to a control circuit provided by the present invention, when the first controller sends the control signal to the load lamp module through the connector, the value of the status register in the first controller is updated based on the control signal;

[0017] The first controller is also configured to, upon determining that the electronic device is powered on, generate a control signal for controlling the load lamp module to not emit light, and then send the control signal to the load lamp module through the connector, and update the value of the status register to a first value;

[0019] The first controller is further configured to, upon receiving a first input signal indicating that the electronic device has successfully loaded and run the operating system, receiving an output signal carrying the same data signal as the analog data signal, and receiving load data sent by the second controller, generate a control signal corresponding to the load data for controlling the load lamp module based on the load data, and then send the control signal to the load lamp module through the connector, and update the value of the status register to the value corresponding to the control signal;

[0020] The first controller is further configured to, upon receiving a second input signal indicating that the electronic device is in a standby state, generate a control signal for controlling the load lamp module to not emit light, and then send the control signal to the load lamp module through the connector, and update the value of the status register to the first value.

[0021] According to a control circuit provided by the present invention, the XOR gate unit is used to send the output signal to the first controller and the second controller;

[0022] The first controller is further configured to send the value of the status register to the second controller, so that the second controller can determine whether the control of the load lamp module is abnormal based on the output signal and the value of the status register, and if it is determined that the control of the load lamp module is abnormal, obtain the reason for the abnormal control of the load lamp module.

[0023] A control circuit according to the present invention further includes: an input / output expander;

[0024] The second controller is connected to the first end of the XNOR gate unit through the input / output expander.

[0025] The present invention also provides a load lamp control method based on any of the control circuits described above, comprising:

[0026] Upon receiving load data sent by the second controller in the electronic device, a control signal for controlling the load lamp module corresponding to the load data is generated based on the load data, and the data signal output by the load lamp module in response to the control signal is simulated to obtain a simulated data signal. The second controller is used to monitor the load status of the target element in the electronic device and obtain the load data of the target element.

[0027] The control signal is sent to the load lamp module so that the load lamp module emits light in response to the control signal;

[0028] Obtain the data signal output by the load lamp module in response to the control signal;

[0029] The data signal and the analog data signal are compared, and an output signal carrying the comparison result is sent to the second controller, and / or the control of the load lamp module continues.

[0030] According to a load lamp control method provided by the present invention, before receiving load data sent by a second controller in an electronic device, generating a control signal corresponding to the load data for controlling the load lamp module based on the load data, and simulating the data signal output by the load lamp module in response to the control signal to obtain the simulated data signal, the method further includes:

[0031] When it is determined that the electronic device is powered on, a first control signal is generated to control the load lamp module to not emit light, and the data signal output by the load lamp module in response to the first control signal is simulated to obtain a first simulated data signal. Then, the first control signal is sent to the load lamp module, and the value of the status register is updated to the first value.

[0032] The first data signal output by the load lamp module in response to the first control signal is obtained, the first data signal and the first analog data signal are compared, and if the first data signal and the first analog data signal are consistent and the value of the status register is the first value, it is determined whether the electronic device is in the power-on state.

[0033] When it is determined that the electronic device is in the powered-on state, a second control signal is generated to control the load lamp module to emit light according to the first light emission mode, the data signal output by the load lamp module in response to the second control signal is simulated to obtain the second simulated data signal, and then the second control signal is sent to the load lamp module, and the value of the status register is updated to the second value.

[0034] The second data signal output by the load lamp module in response to the second control signal is obtained, the second data signal and the second analog data signal are compared, and if the second data signal and the second analog data signal are consistent, it is determined whether the electronic device has successfully loaded and run the operating system.

[0035] If it is determined that the electronic device has successfully loaded and run the operating system, a third control signal is generated to control the load lamp module to emit light in the second light emission mode, the data signal output by the load lamp module in response to the third control signal is simulated to obtain a third simulated data signal, and then the third control signal is sent to the load lamp module, and the value of the status register is updated to the third value.

[0036] The third data signal output by the load lamp module in response to the third control signal is obtained. The third data signal and the third analog data signal are compared. If the third data signal and the third analog data signal are consistent, and if the second controller sends load data, then a control signal for controlling the load lamp module corresponding to the load data is generated based on the load data.

The control circuit includes a first controller, a connector, and a XNOR gate unit. The first controller generates a control signal for controlling the load lamp module based on load data sent by a second controller in the electronic device. The first controller then sends the control signal to the load lamp module through the connector. The connector acquires the data signal output by the load lamp module in response to the control signal and sends the data signal to the XNOR gate unit. Based on the load data sent by the second controller, the first controller simulates the data signal output by the load lamp module.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] In the description of this application, the terms "first," "second," etc., are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the description of this application, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0050] It should be noted that with the rapid development of big data, artificial intelligence, cloud computing, and other fields, the application scenarios and demands for servers are increasing. A server's performance, computing power, and functionality are all related to its CPU; therefore, the CPU load status within a server is crucial operational data for server management.

[0051] For operations and maintenance engineers in data centers, a simple and convenient way to understand the CPU load status of each server can provide a reference for judging the operating status of the server's power supply, heat dissipation, and other aspects, as well as for on-site server maintenance.

[0052] Therefore, in related technologies, a load indicator light is designed on the server to display the CPU load status in real time on the front window mounting bracket. The load indicator light can emit different light signals based on the CPU load status in the server, so that the operation and maintenance engineers in the data center can easily and conveniently understand the CPU load status in the server based on the light signals emitted by the load indicator light.

[0053] Typically, control circuits can control the illumination signal emitted by the load lamp. However, traditional control circuits in related technologies cannot obtain the actual illumination status of the load lamp.

[0054] When testers test load lamps, the actual lighting status of the load lamps can only be determined by the testers' on-site observation. Testers cannot remotely obtain the lighting status of the load lamps through components such as the Baseboard Management Controller (BMC), and therefore cannot remotely obtain the test results of the load lamps based on whether the actual lighting status of the load lamps meets expectations. The manpower and time costs required to test load lamps are relatively high.

[0055] Furthermore, even if the testers determine through on-site observation that the actual lighting status of the load lights does not meet expectations, the testers are still unable to directly and effectively locate the cause of the anomaly and must go to the computer room to perform unpacking and other operations.

[0056] The following is combined Figures 1-2 A control circuit of the present invention is described.

[0057] Figure 1 This is a 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.

[0058] The first terminal of the first controller 102 is connected to the first terminal of the second controller 106 and the first terminal of the XOR gate unit 104 in the electronic device 105. The second terminal of the XOR gate unit 104 is connected to the second terminal of the connector 103. The third terminal of the XOR gate unit 104 is connected to the second terminal of the first controller 102. The third terminal of the first controller 102 is connected to the third terminal of the connector 103. The fifth terminal of the connector 103 is connected to the load lamp module 107. The load lamp module 107 includes a plurality of load lamps. The second controller 106 is used to monitor the load status of the target component 108 in the electronic device 105 and acquire the load data of the target component 108.

[0059] The first controller 102 is used to generate a control signal for controlling the load lamp module 107 based on the load data when it receives the load data sent by the second controller 106, and then send the control signal to the load lamp module 107 through the connector 103 so that the load lamp module 107 can emit light in response to the control signal. The first controller 102 is also used to simulate the data signal output by the load lamp module 107 based on the load data, and after obtaining the simulated data signal, send the simulated data signal to the XOR gate unit 104.

[0060] Connector 103 is used to acquire the data signal output by the load lamp module 107 in response to the control signal, and send the data signal to the XOR gate unit 104.

[0061] The NAND gate unit 104 is used to compare the data signal and the analog data signal when a data signal and an analog data signal are received, and then send an output signal carrying the comparison result to the first controller 102 and / or the second controller 106.

[0062] The first controller 102 is also configured to determine, upon receiving an output signal, whether to continue controlling the load lamp module 107 based on the output signal.

[0063] It should be noted that the control circuit 101 in this embodiment of the invention is used to control the load lamp module 107. The load lamp module 107 is used to indicate the load status of the target component 108 in the electronic device 105. The electronic device 105 may include, but is not limited to, electronic devices such as computers and servers.

[0064] It is understood that the target element 108 in the electronic device 105 in this embodiment of the invention can be determined based on actual needs. For example, the target element 108 can be the central processing unit (CPU) in the electronic device 105. This embodiment of the invention does not impose specific limitations on the target element 108 in the electronic device 105.

[0065] Optionally, in this embodiment of the invention, the first controller 102 in the control circuit 101 can be a controller with high programmability, flexibility, and integration, such as a Complex Programmable Logic Device (CPLD), a Field-Programmable Gate Array (FPGA), or a System on Chip (SoC). The specific type of the first controller 102 is not limited in this embodiment of the invention.

[0066] The second controller 106 in the electronic device 105 can monitor the load status of the target element 108 in the electronic device 105 and acquire the load data of the target element 108.

[0067] As an optional embodiment, the second controller 106 is a baseboard management controller, which is connected to the first controller 102 via a data bus, including an I2C data bus.

[0068] Upon receiving the load data sent by the second controller, the first controller 102 can generate a control signal (FM_LOAD_LED signal) corresponding to the load data for controlling the load lamp module 107.

[0069] When the first controller 102 generates the aforementioned control signal, it can send the control signal to the connector 103 through the third terminal of the first controller 102 and the third terminal of the connector 103.

[0070] When the connector 103 receives the control signal, it can send the control signal to the load lamp module 107 through the fifth terminal of the connector 103.

[0071] When the load lamp module 107 receives the control signal, it can emit light according to the light emission mode corresponding to the control signal.

[0072] When the load lamp module 107 receives the control signal, it can respond to the control signal and output the corresponding data signal (LOAD_LED_DOUT signal).

[0073] Connector 103 can acquire the data signal output by the load lamp module 107 in response to the control signal, and send the data signal to the XOR gate unit 104.

[0074] 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.

[0075] When the load lamp module 107 includes multiple 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 of the load lamp module 107 in response to the control signal.

[0076] As an optional embodiment, when the load lamp module 107 includes multiple load lamps, the load lamps are connected in series, and each load lamp includes a light-emitting module and a control module.

[0077] Connector 103 is used to input the control signal into the control module of the first load lamp in each load lamp connected in series, and then obtain the data signal output by the control module of the last load lamp in each load lamp, as the data signal output by the load lamp module 107 in response to the control signal.

[0078] The first controller 102 is used to, upon receiving load data sent by the second controller 106, simulate the data signal output by the control module of the last load lamp in each series of load lamps as an analog data signal.

[0079] It is understood that the load lamp in the embodiments of the present invention includes a light-emitting module and a control module. The control module of the load lamp can respond to the input control signal and control the light-emitting module to emit light according to the light-emitting mode corresponding to the control signal.

[0080] Figure 2 This is a schematic diagram of the flow of control signals in the control circuit provided by the present invention. For example... Figure 2 As shown, when 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.

[0081] 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 flows sequentially through each load lamp connected in series in the load lamp module 107 to the control module of the Nth load lamp in the load lamp module 107.

[0082] The control module of the Nth load lamp in the load lamp module 107 responds to the input control signal and outputs the data signal corresponding to the control signal.

[0083] The sixth end of connector 103 can be connected to the control module of the Nth load lamp in the load lamp module 107. 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 load lamp module 107 in response to the control signal.

[0084] Upon 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 aforementioned load data, obtain the analog data signal (FM_LOAD_LED_DOUT signal), and then send the analog data signal to the XOR gate unit 104.

[0085] Accordingly, when 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 aforementioned load data, and uses it as a simulated data signal.

[0086] When the load lamp module 107 includes multiple load lamps, the first controller 102 simulates the data signal output by the control module of the Nth load lamp in the load lamp module 107 based on the above-mentioned load data, and uses it as the simulated data signal.

[0087] After the first controller 102 acquires the analog data signal, it can send the analog data signal to the XOR gate.

[0088] 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.

[0089] When the XOR gate receives 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, it can generate an output signal (LOAD_LED_FAULT_N signal) carrying the comparison result of the data signal and the analog data signal.

[0090] Table 1 is a functional description table of the output signal (LOAD_LED_FAULT_N signal). As shown in Table 1, in this embodiment of the invention, "1" and "0" can be used to represent the comparison result of the above data signal and the above analog data signal. When the above output signal carries "1", it means that the above data signal and the above analog data signal are the same, which can be used to indicate 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 output signal carries "0", it means that the above data signal and the above analog data signal are different, which can be used to indicate 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.

[0091] Table 1. Functional Description of Output Signals (LOAD_LED_FAULT_N Signals)

[0092]

[0093] After the XOR gate generates an output signal carrying the comparison result of the above data signal and the above analog data signal, the output signal can be sent to the second controller 106.

[0094] Based on the aforementioned output signals, the second controller 106 can determine whether the actual lighting state of the load lamp module 107 meets expectations, and thus determine that the load lamp module 107 is not malfunctioning. The second controller 106 can also issue an alarm if it determines that the actual lighting state of the load lamp module 107 does not meet expectations. The second controller 106 can also send the aforementioned output signals to a remote testing terminal, allowing testers to remotely monitor the actual lighting state of the load lamp module 107 and perform remote testing on the load lamp module 107.

[0095] After the XOR gate generates an output signal carrying the comparison result of the above data signal and the above analog data signal, the output signal can be sent to the first controller 102.

[0096] Based on the aforementioned output signal, the first controller 102 can determine whether to continue controlling the load lamp module 107.

[0097] The control circuit in this embodiment of the invention includes a first controller, a connector, and a XNOR gate unit. The first controller generates a control signal for controlling the load lamp module based on load data sent by a second controller in the electronic device. The first controller then sends the control signal to the load lamp module via the connector. The connector acquires the data signal output by the load lamp module in response to the control signal and sends the data signal to the XNOR gate unit. Based on the load data sent by the second controller, the first controller simulates the data signal output by the load lamp module. After obtaining the simulated data signal, it sends the simulated data signal to the XNOR gate unit. The XNOR gate unit is used to process the received data signal and simulated data signal. The circuit compares the signals and then sends an output signal carrying the comparison result to the first controller and / or the second controller. When the control circuit controls the load lamp module, the second controller in the electronic device can remotely monitor whether the actual lighting status of the load lamp module meets the expectations. Therefore, when testing the load lamp module, there is no need for testers to go to the airport site to observe the actual lighting status of the load lamp module. The test results of the load lamp module can be obtained, which can reduce the manpower and time costs required for load lamp module testing, improve the efficiency of load lamp module testing, monitor the actual lighting status of the load lamp module in real time, and promptly detect potential faults of the load lamp module, thereby improving the operational stability of the electronic device.

[0098] like Figure 1 As shown, as an optional embodiment, it also includes an input / output expander 109.

[0099] Both the first controller 102 and the second controller 106 are connected to the first end of the XNOR gate unit 104 via the input / output expander 109.

[0100] It should be noted that the Input / Output Expander 109, or simply IO Expander, is a hardware device or chip used to increase the number or functionality of I / O interfaces on a microcontroller, computer, or other computing device. These expanders typically communicate with the main controller via a bus (such as I2C, SPI, UART, etc.) and allow the main controller to control more peripherals or read more data from external devices.

[0101] Optionally, in this embodiment of the invention, the input / output expander 109 may be a CA9555.

[0102] As an optional embodiment, the first end of connector 103 is used to input a standby voltage signal, and the fourth end of connector 103 is used to ground.

[0103] It should be noted that the standby voltage (P5V_STBY) signal represents a voltage signal that continues to supply power to the motherboard while it is in standby mode. The standby voltage signal is an important signal in the power management system of electronic devices, used to provide standby voltage support for critical components of the system and playing a crucial role in the system's power-on sequence.

[0104] The first controller 102 can determine whether the electronic device 105 is powered on based on the input standby voltage signal received by the connector 103.

[0105] As an optional embodiment, the third terminal 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 terminal of the first controller 102 is used to input a second input signal indicating the operating status of the electronic device 105.

[0106] It should be noted that if the first input signal (80 port signal) of the first controller 102 does not carry "0x04", it means that the electronic device 105 has not successfully loaded and run the operating system; if the first input signal (80 port signal) of the first controller 102 carries "0x04", it means that the electronic device 105 has successfully loaded and run the operating system.

[0107] The first controller 102 can determine whether the electronic device 105 has successfully loaded and run the operating system based on the first input signal.

[0108] It should be noted that when the second input signal (SLP4 signal) of the first controller 102 carries a "1", it indicates that the electronic device 105 is in the power-on state; when the second input signal (SLP4 signal) of the first controller 102 carries a "0", it indicates that the electronic device 105 is in the standby state.

[0109] The first controller 102 can determine the operating status of the electronic device 105 based on the input second input signal.

[0110] As an optional embodiment, when the first controller 102 sends a control signal to the load lamp module 107 via connector 103, the value of the status register in the first controller 102 is updated based on the control signal.

[0111] The first controller 102 is also used to generate a control signal for controlling the load lamp module 107 to not emit light when it is determined that the electronic device 105 is powered on, and then send the control signal to the load lamp module 107 through the connector 103, and update the value of the status register to the first value.

[0112] The first controller 102 is also configured to generate a control signal for controlling the load lamp module 107 to emit light in a first light-emitting mode when it receives a second input signal indicating that the electronic device 105 is in the power-on state and an output signal carrying the same data signal and analog data signal, and then send the control signal to the load lamp module 107 through the connector 103 and update the value of the status register to the second value.

[0113] The first controller 102 is also configured to, upon receiving a first input signal indicating that the electronic device 105 has successfully loaded and run the operating system, receiving an output signal carrying the same data signal and analog data signal, and receiving load data sent by the second controller 106, generate a control signal corresponding to the load data for controlling the load lamp module 107 based on the load data, and then send the control signal to the load lamp module 107 through the connector 103, and update the value of the status register to the value corresponding to the control signal.

[0114] The first controller 102 is also configured to generate a control signal for controlling the load lamp module 107 to not emit light when receiving a second input signal indicating that the electronic device 105 is in a standby state, and then send the control signal to the load lamp module 107 through the connector 103, and update the value of the status register to the first value.

[0115] It should be noted that the code of the first controller 102 in this embodiment of the 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.

[0116] It should be noted that the correspondence between the value of the status register in the first controller 102 and the control signal, as well as the correspondence between the value of the status register and the operating state of the electronic device 105 in this embodiment of the invention, can be determined based on existing knowledge and / or actual conditions.

[0117] Optionally, in this embodiment of the invention, the value of the status register in the first controller 102 includes a four-bit binary value. Table 2 is a functional description table of the value of the fourth bit of the status register in the first controller. As shown in Table 2, in this embodiment of the invention, "1" and "0" can be used to represent the operating state of the electronic device 105. When the fourth bit of the status register in the first controller 102 is "1", it indicates that the electronic device 105 is in the power-on state; when the value of the fourth bit of the status register in the first controller 102 is "0", it indicates that the electronic device 105 is in the standby state.

[0118] Table 2. Functional description of the fourth bit value in the status register of the first controller.

[0119]

[0120] Table 3 is a functional description table of the first to third bits of the status register in the first controller. As shown in Table 3, the functions of the first to third bits of the status register in the first controller 102 are as shown in Table 3.

[0121] Table 3. Functional description of the values ​​of the first to third bits of the status register in the first controller.

[0122]

[0123] In this invention, the light emission modes can be determined based on prior knowledge and / or actual conditions. For example, the first light emission mode includes a green running light pattern; the second light emission mode includes a constant green light; the third light emission mode includes a constant green light; the fourth light emission mode includes a constant blue light; and the fifth light emission mode includes a constant yellow light. Green indicates a light load, blue indicates a medium load, and yellow indicates a high load. This invention does not specifically limit the light emission modes.

[0124] The control circuit in this embodiment of the invention controls the load lamp module based on the operating status of the electronic device and whether the operating system has been successfully loaded and run. It can also control the load lamp module based on the received load data when it is determined that the electronic device is powered on and the operating system has been successfully loaded and run, thereby further improving the reliability and flexibility of controlling the load lamp module.

[0125] As an optional embodiment, the XOR gate unit 104 is used to send the output signal to the first controller 102 and the second controller 106.

[0126] 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 the control of the load lamp module 107 is abnormal based on the output signal and the value of the status register, and if it is determined that the control of the load lamp module 107 is abnormal, obtain the reason for the abnormal control of the load lamp module 107.

[0127] Specifically, the first controller 102 can send the updated value of the status register to the second controller 106 after each update of the status register value.

[0128] When the second controller 106 receives the output signal sent by the XOR gate unit 104, which carries the comparison result of the data signal and the analog data signal, it can determine whether the control of the load lamp module 107 is abnormal based on the output signal and the value of the status register of the first controller 102 most recently received. If it is determined that the control of the load lamp module 107 is abnormal, the second controller 106 can obtain the reason for the abnormal control of the load lamp module 107.

[0129] Table 4 shows the correspondence between the values ​​carried by the output signals, the values ​​in the status register of the first controller, and the reasons that cause the load lamp module 107 to malfunction. The correspondence between the values ​​carried by the output signals, the values ​​in the status register of the first controller 102, and the reasons that cause the load lamp module 107 to malfunction is shown in Table 4.

[0130] Table 4. Correspondence between the values ​​carried by the output signals (LOAD_LED_FAULT_N signal), the values ​​in the status register of the first controller, and the causes of abnormalities in the load lamp module 107.

[0131]

[0132] It should be noted that "X" in Table 4 represents "0" or "1". The correspondence between the values ​​carried by the output signals (LOAD_LED_FAULT_N signals) and the values ​​of the status register of the first controller 102 shown in Table 4 and the reasons for the abnormality of the load lamp module 107 is determined based on the functional descriptions of the values ​​of the status registers in the first controller 102 shown in Tables 2 and 3.

[0133] It is understandable that the combination of the value carried by the output signal and the value of the status 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.

[0134] The control circuit in this embodiment of the invention sends the output signal to the first controller and the second controller through an XOR gate unit. The first controller sends the value of the status register to the second controller, so that the second controller can determine whether the control of the load lamp module is abnormal based on the output signal and the value of the status register. If it is determined that the control of the load lamp module is abnormal, the second controller can obtain the cause of the abnormality. This can locate the cause of the abnormality more efficiently and accurately, and further improve the testing efficiency and maintenance efficiency of the load lamp module.

[0135] Figure 3 This is one of the flowcharts illustrating 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 described above. Figure 3 As shown, the method includes the following steps: Step 301: Upon receiving load data sent by the second controller 106 in the electronic device 105, based on the load data, a control signal corresponding to the load data is generated for controlling the load lamp module 107, and the data signal output by the load lamp 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 status of the target element 108 in the electronic device 105 and to obtain the load data of the target element 108.

[0136] Step 302: Send a control signal to the load lamp module 107 so that the load lamp module 107 can emit light in response to the control signal.

[0137] Step 303: Obtain the data signal output by the load lamp module 107 in response to the control signal.

[0138] Step 304: Compare the data signal and the analog data signal, send the output signal carrying the comparison result to the second controller 106, and / or continue to execute the control of the load lamp module 107.

[0139] It should be noted that the execution subject of this embodiment of the invention is the control circuit 101 described above.

[0140] It should be noted that the load lamp control method provided by this invention is implemented based on the control circuit 101 described above. The specific execution steps of the load lamp control method can be found in the descriptions of the above embodiments. Further details are omitted in the embodiments of this invention.

[0141] This invention, upon receiving load data from a second controller in an electronic device, generates a control signal for a load lamp module and a simulated data signal output by the load lamp module based on the load data, obtaining a simulated data signal. The second controller monitors the load status of a target component in the electronic device, acquires the load data of the target component, sends the control signal to the load lamp module so that the load lamp module illuminates in response to the control signal, acquires the data signal output by the load lamp module in response to the control signal, compares the data signal and the simulated data signal, sends an output signal carrying the comparison result to the second controller, and / or continues to execute control of the load lamp module. This allows the second controller in the electronic device to remotely monitor whether the actual lighting status of the load lamp module meets expectations. When testing the load lamp module, there is no need for testers to go to the airport site to observe the actual lighting status of the load lamp module; test results can be obtained without this, reducing the manpower and time costs required for load lamp module testing, improving the efficiency of load lamp module testing, enabling real-time monitoring of the actual lighting status of the load lamp module, and timely detection of potential faults in the load lamp module, thereby improving the operational stability of the electronic device.

[0142] As an optional embodiment, upon receiving load data sent by the second controller 106 in the electronic device 105, before generating a control signal for controlling the load lamp module 107 based on the load data and simulating the data signal output by the load lamp module 107 in response to the control signal to obtain the simulated data signal, the method further includes: upon determining that the electronic device 105 is powered on, generating a first control signal for controlling the load lamp module 107 to not emit light, simulating the data signal output by the load lamp module 107 in response to the first control signal to obtain the first simulated data signal, and then sending the first control signal to the load lamp module 107 and updating the value of the status register to the first value.

[0143] The system acquires 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 determines whether the electronic device 105 is in the power-on state if the first data signal and the first analog data signal are consistent and the value of the status register is the first value.

[0144] When it is determined that the electronic device 105 is powered on, a second control signal is generated to control the load lamp module 107 to emit light in accordance with the first light emission mode. The data signal output by the load lamp module 107 in response to the second control signal is simulated to obtain the second analog data signal. Then, the second control signal is sent to the load lamp module 107, and the value of the status register is updated to the second value.

[0145] The system acquires 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 determines whether the electronic device 105 has successfully loaded and run the operating system if the second data signal and the second analog data signal are consistent.

[0146] Once 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 lamp module 107 to emit light in accordance with the second light emission mode. The data signal output by the load lamp module 107 in response to the third control signal is simulated to obtain the third analog data signal. Then, the third control signal is sent to the load lamp module 107, and the value of the status register is updated to the third value.

[0147] The third data signal output by the load lamp module 107 in response to the third control signal is obtained. The third data signal and the third analog data signal are compared. If the third data signal and the third analog data signal are consistent, and the second controller 106 sends load data, then the control signal corresponding to the load data is generated based on the load data.

[0148] Figure 4 This is the second flowchart illustrating the load lamp control method provided by this invention. The following is in conjunction with... Figure 4 Tables 2 and 3 illustrate the load lamp control method in the embodiments of the present invention.

[0149] When the first controller 102 determines that the electronic device 105 is powered on, it generates a first control signal (FM_LOAD_LED signal) to control the load lamp module 107 to not emit light, and then sends the first control signal to the load lamp module 107 through the connector 103, and updates the value of the status register to the first value ("0000").

[0150] The XOR gate unit 104 acquires 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.

[0151] If the first controller 102 determines that the output signal (LOAD_LED_FAULT_N signal) carries a value of "1" and the value of the status register is the first value ("0000"), then the first controller 102 determines whether the electronic device 105 is in the powered-on state based on the received second input signal.

[0152] When the first controller 102 receives a 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 keeps the value of the status register at the first value ("0000").

[0153] When the first controller 102 receives a second input signal (SLP4 signal) carrying a "1", it indicates that the electronic device 105 is in the power-on state. The first controller 102 generates a second control signal (FM_LOAD_LED signal) to control the load lamp module 107 to emit light according to the first light emission mode. It simulates the data signal output by the load lamp module 107 in response to the second control signal, obtains the second analog data signal, and then sends the second control signal to the load lamp module 107 and updates the value of the status register to the second value ("1010").

[0154] The XOR gate unit 104 acquires 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.

[0155] If the first controller 102 determines that the value carried by the output signal (LOAD_LED_FAULT_N signal) is "1", then 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 has been received.

[0156] If the first controller 102 does not receive the first input signal (80 port signal) carrying "0x04" or does not receive 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. The first controller 102 then returns to determine whether the second input signal (SLP4 signal) carrying "1" has been received.

[0157] 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. The first controller 102 generates a third control signal to control the load lamp module 107 to emit light according to the second light emission mode, simulates the data signal output by the load lamp module 107 in response to the third control signal, obtains the third analog data signal, and then sends the third control signal to the load lamp module 107 and updates the value of the status register to the third value ("1100").

[0158] The XOR gate unit 104 acquires 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.

[0159] 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 load lamp module 107 responding to the data signal output by the control signal, obtains the analog data signal corresponding to the load data, and then sends the control signal to the load lamp module 107 and updates the value of the status register to the value corresponding to the control signal.

[0160] The XOR gate unit 104 acquires 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.

[0161] When the first controller 102 determines that the output signal (LOAD_LED_FAULT_N signal) carries a value of "1" and the value of the status register is "11XX", the first controller 102 determines that it has received a second input signal (SLP4 signal) carrying a value of "0".

[0162] Even without receiving a 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.

[0163] When the first controller 102 receives a second input signal (SLP4 signal) carrying "0", it terminates the control of the load lamp module 107.

[0164] The XNOR gate unit 104 can send each generated output signal (LOAD_LED_FAULT_N signal) to the second controller 106. Correspondingly, after each update of the status register value, the first controller 102 sends the updated status register value to the second controller 106. This allows the second controller to determine whether the control of the load lamp module 107 is abnormal based on the output signal (LOAD_LED_FAULT_N signal) and the status register value. If it is determined that the control of the load lamp module 107 is abnormal, the second controller can obtain the cause of the abnormal control of the load lamp module 107.

[0165] The first controller 102 can also send the output signal (LOAD_LED_FAULT_N signal) with a value of "0" and the current value of the first controller 102 status register to the second controller 106 when it determines that the output signal (LOAD_LED_FAULT_N signal) with a value of "0" is "0". The second controller 106 records the output signal (LOAD_LED_FAULT_N signal) with a value of "0" and the current value of the first controller 102 status register, and obtains the reason for the abnormal control of the load lamp module 107 based on the output signal (LOAD_LED_FAULT_N signal) with a value of "0" and the current value of the first controller 102 status register.
