[0056] Some embodiments of the present disclosure will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatuses, and / or systems described herein will become apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those set forth herein, but may be changed as will be apparent after understanding the present disclosure, except for operations that must be performed in a specific order. Additionally, descriptions of features known in the art may be omitted for increased clarity and brevity.
[0057] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0058] The electronic device, its control method, control system, and storage medium proposed in the embodiments of the present disclosure are introduced below with reference to the accompanying drawings.
[0059] Figure 1 is a schematic diagram of a control system of an electronic device according to an embodiment of the present disclosure.
[0060] As Figure 1As shown, the control system 100 of the electronic device according to an embodiment of the present disclosure includes: a plurality of power management integrated circuits PMIC 102, a communication bus 111, and a system on chip SOC 101.
[0061] Among them, the plurality of PMICs 102 include a first PMIC 102, a second PMIC 102,..., an nth PMIC 102. As Figure 2 shown, an overtemperature monitor 103 and an overcurrent monitor 104 are provided in each PMIC 102. The overtemperature monitor 103 is used to monitor whether the corresponding power module has an overtemperature, and the overcurrent monitor 104 is used to monitor whether the corresponding power module has an overcurrent. The communication interfaces of each PMIC 102 and the communication interface of the SOC 101 are both connected to the communication bus 111. Each PMIC 102 is used to detect the working state (such as temperature and current information) of the corresponding power module, and generate a warning message when the working state of the corresponding power module is abnormal. The communication bus 111 is used to send the warning message generated by the target PMIC 102 among the plurality of PMICs 102 to the SOC 101. The SOC 101 is used to receive the warning message sent by the target PMIC 102, and protect the corresponding power module in the electronic device according to the warning message.
[0062] For example, when the first PMIC 102 detects that the first power module is overloaded or overheated, it actively sends a warning message to the SOC 101 through the communication bus 111. After receiving the warning message, the SOC 101 protects the first power module in the electronic device. Among them, when the SOC 101 protects the corresponding power module in the electronic device according to the warning message, it can adopt at least one of the following protection strategies: sending a first control signal to the frequency controller 108 in the electronic device to instruct the frequency controller 108 to reduce the working frequency of the load; sending a first interrupt signal to the load processor 109 in the electronic device to instruct the load processor 109 to reduce the allowed working load.
[0063] In an embodiment of the present disclosure, each PMIC 102 is further used to generate a prompt message when it obtains that the working state of the corresponding power module has recovered from abnormal to normal; the communication bus 111 is further used to send the prompt message generated by the target PMIC 102 to the SOC 101; the SOC 101 is further used to perform a recovery process on the load capacity of the corresponding power module in the electronic device according to the prompt message. Among them, when the SOC 101 performs a recovery process on the load capacity of the corresponding power module in the electronic device according to the prompt message, it can adopt at least one of the following control strategies: sending a second control signal to the frequency controller 108 in the electronic device to instruct the frequency controller 108 to increase the working frequency of the load; sending a second interrupt signal to the load processor 109 in the electronic device to instruct the load processor 109 to increase the allowed working load.
[0064] As Figure 2 shown, the control system 100 of the above-mentioned electronic device further includes: an encoder 105 and a decoder 106 having the same number as the PMIC 102. Among them, each encoder 105 is used to encode the warning information generated by each PMIC 102, and send the encoded warning information through the communication bus 111. The decoder 106 is used to receive the encoded warning information sent by the target PMIC 102 through the communication bus 111, and decode the encoded warning information to obtain the warning information.
[0065] It should be noted that the serial communication protocol of the communication bus 111 in the present disclosure needs to support the PMIC 102 to initiate communication with the SOC 101 actively. At the same time, the hardware logic on the PMIC 102 side needs to support automatically encoding the warning information of the overtemperature monitor 103 and the overcurrent monitor 104, and sending the encoded warning information to the SOC 101 through the communication bus 111 interface on the PMIC 102 side. After the communication bus 111 interface on the SOC 101 side receives the encoded warning information, the hardware logic on the SOC 101 side also needs to support automatically decoding the relevant overcurrent and / or overtemperature warning information and providing it to the protection controller 107. In addition, the hardware logic on the PMIC 102 side also needs to support automatically encoding the prompt information and sending the encoded prompt information to the SOC 101 through the communication bus 111 interface on the PMIC 102 side. After the communication bus 111 interface on the SOC 101 side receives the encoded prompt information, the hardware logic on the SOC 101 side also needs to support automatically decoding the relevant prompt information and providing it to the protection controller 107. The protection controller 107 needs to support initiating corresponding frequency reduction or frequency restoration to the frequency controller 108 through a control signal, or notifying the load processor 109 to perform corresponding load reduction or load restoration through an interrupt signal.
[0066] Next, in combination with Figure 3 the working principle of the control system of the electronic device of the present disclosure will be described:
[0067] After the overtemperature monitor 103 and overcurrent monitor 104 inside the PMIC102 detect an overtemperature or overcurrent behavior in the corresponding power module, warning messages 201, 202, …, 203 are sent out. The hardware logic on the PMIC102 side encodes the warning messages through the encoder 106 and sends the encoded warning messages to the SOC101 through the serial communication protocol of the communication bus 111. After the communication bus interface of the SOC101 receives the encoded warning messages, it decodes the relevant overcurrent and overtemperature warning messages through the decoder 106 and provides them to the protection controller 107. The protection controller 107 initiates a frequency reduction process 206 for the frequency controller 108 through a control signal, and / or notifies the load processor 109 to reduce the load through an interrupt signal 205. After the PMIC102 detects that the abnormal conditions of overtemperature and overcurrent disappear, it sends out prompt messages 201, 202, …, 203, which are sent to the SOC101 through the same transmission path. After the SOC101 receives the prompt messages, they are passed to the protection controller 107, and a normal frequency is restored for the frequency controller 108 through a control signal 206, and / or the load processor 109 is notified to restore the normal load through an interrupt signal 205. Exemplarily, the serial communication bus of the present disclosure may include an SPI (Serial Peripheral Interface) bus.
[0068] The present disclosure is compared with the related art as follows: In the related art, the SOC communicates with other chips by adding separate functional lines (such as interrupt lines) to transmit some specific information (such as interrupt information), or by setting up specific interfaces to transmit specific information. This will occupy hardware resources such as the pins of the SOC, which is not conducive to chip miniaturization, and the encoding and decoding of the specific information transmitted by the separate functional lines are relatively complex. However, in the present disclosure, the connection between the PMIC and the SOC is close, and warning messages and prompt messages are transmitted through a serial bus, without the need to separately set functional lines. In addition, the encoding and decoding of the warning messages and prompt messages transmitted through the communication bus are easier.
[0069] To enable those skilled in the art to understand the present disclosure more clearly, the working process of the control system of the electronic device of the present disclosure is described below in conjunction with Figure 4 As shown in Figure 4 the working process of the control system of the electronic device of the present disclosure includes the following steps:
[0070] S401, After the PMIC side detects an overtemperature or overcurrent behavior, warning messages are sent out.
[0071] S402, The PMIC side encodes the warning messages and sends the encoded warning messages to the SOC through the communication bus.
[0072] S403, The communication bus on the SOC side receives the encoded warning information, decodes the encoded warning information to obtain the warning information, and sends the warning information to the protection controller.
[0073] It should be noted that after step S403, at least one of steps S404 and S405 can be executed.
[0074] S404, The protection controller notifies the software to perform a load reduction behavior through an interrupt signal.
[0075] S405, The protection controller directly reduces the load frequency through a control signal.
[0076] S406, The PMIC side monitors that the over-temperature or over-current situation disappears and issues a prompt message.
[0077] S407, The PMIC side encodes the prompt message and sends the encoded prompt message to the SOC through the communication bus.
[0078] S408, After the communication bus on the SOC side receives the encoded prompt message, it decodes the message to obtain the prompt message and sends the prompt message to the protection controller.
[0079] It should be noted that after step S408, step S409 or S410 is selectively executed according to the steps executed after step S403 above. Among them, if the step executed after step S403 above is S404, then step S409 is executed after step S408; if the step executed after step S403 above is S405, then step S410 is executed after step S408.
[0080] S409, The protection controller notifies the software to resume normal load through an interrupt signal.
[0081] S410, The protection controller restores the normal load frequency through a control signal.
[0082] In summary, the control system of the electronic device according to the embodiments of the present disclosure includes multiple power management integrated circuits (PMICs), a communication bus, and a system on chip (SOC). The communication interfaces of each PMIC and the communication interface of the SOC are both connected to the communication bus. Among them, each PMIC is used to detect the working state of the corresponding power module and generate a warning message when the working state of the corresponding power module is abnormal. The communication bus is used to send the warning message generated by the target PMIC among the multiple PMICs to the SOC. The SOC is used to receive the warning message sent by the target PMIC and protect the corresponding power module in the electronic device according to the warning message. Thus, the present disclosure does not require additional communication buses or input / output port resources, nor does it require the SOC to query again. Instead, the PMIC uses the existing communication bus to transmit the warning message to the SOC, and the SOC protects the power module in the electronic device according to the warning message, thereby strengthening the abnormal control of the power module, improving the efficiency of the SOC in handling power module abnormalities, reducing permanent physical damage to the chip, and effectively defending against damage to the chip caused by overload and over-temperature events.
