[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] According to an embodiment of the present invention, a system for controlling power-on of a main control module is provided. Figure 1 is a structural block diagram of a system for controlling the power-on of a main control module according to an embodiment of the present invention. Figure 1 As shown, the system includes: a clock chip 102, an external circuit 104 and a main control module 106, wherein the clock chip is connected to the external circuit, and the clock chip is used to transmit a trigger signal to the external circuit when the trigger time arrives; the external circuit is connected to the main control module, and the external circuit is used to control the main control module to power on through a field effect transistor when receiving the trigger signal.

[0026] The clock chip can be an RTC chip, which is used to transmit a trigger signal to an external circuit to control the main control module to power on when the set trigger time arrives. The external circuit has a field effect tube (such as Figure 1 100 shown in FIG. 1 ), after receiving the trigger signal, the field effect tube 100 is turned on, and the main control module is powered on immediately. After the main control module is powered on, it is in the power-on state.

[0027] Through the above system structure, based on the clock chip to provide accurate real-time time, after the preset time is reached, the external circuit can be turned on, so that the main control module can be turned on. Because in static operation, only power needs to be provided to the clock chip to ensure normal timing of the clock chip. When the clock chip is timing only, the power consumption is very low, and the power consumption is only at the microampere level, thereby solving the problem of high static power consumption of vehicle-mounted equipment and achieving the effect of automatic power on and off function of vehicle-mounted equipment with extremely low static power consumption.

[0028] In an exemplary embodiment, the external circuit is connected to the main control module, including: the field effect transistor in the external circuit is connected to the enable end of the main control module, wherein when the external circuit receives the trigger signal, the field effect transistor is turned on so that the enable end of the main control module is pulled high, thereby controlling the main control module to power on.

[0029] like Figure 1 As shown in , the enable terminal of the main control module (such as Figure 1 The entire main control module can only be powered on after the level of 116) shown in the figure is pulled high. The external circuit is connected to the enable end of the main control module. After the field effect tube is turned on, the power supply device has power, and the level of the enable end of the main control module will be pulled high, so that the main control module will be powered on and automatic startup will be achieved.

[0030] In an exemplary embodiment, the field effect transistor in the external circuit is connected to the enable end of the main control module, including: the field effect transistor is connected to the enable end of the main control module through a first diode, wherein the field effect transistor is connected to the anode of the first diode, and the enable end is connected to the cathode of the first diode.

[0031] It should be noted that through a diode (such as Figure 1 108) shown in the figure connects the field effect tube and the enable terminal of the main control module. After the field effect tube is turned on, the current is conducted from the field effect tube to the enable terminal of the main control module, but reverse conduction is impossible.

[0032] In an exemplary embodiment, the above-mentioned system also includes: the enable end of the main control module is connected to the input and output ends of the main control module through a second diode, wherein the input and output ends are connected to the positive electrode of the second diode, and the enable end is connected to the negative electrode of the second diode, and after the enable end of the main control module is pulled high, the main control module pulls up the input and output ends to pull up the enable end through the input and output ends.

[0033] It should be noted that after the enable terminal of the main control module is pulled high, the input and output terminals of the main control module (such as Figure 1 114) will be pulled up accordingly, and the input and output terminals of the main control module are connected to the enable module. After the level of the input and output terminals is pulled up, the level of the enable terminal will be pulled up to ensure that when the clock chip does not transmit the trigger signal, the level of the main control module is still in the pulled-up state, and the main control module will not shut down with the disappearance of the trigger signal. Figure 1 110) shown in FIG. 1 can realize unidirectional conduction by connecting the input and output terminals and the enable terminal.

[0034] It should be noted that the clock chip transmits the trigger signal to the external circuit periodically. After one trigger, there is no continuous trigger signal to be transmitted to the external circuit. At this time, the field effect tube in the external circuit will change from the on state to the off state. At this time, the enable end cannot be kept at a high level through the power supply equipment; through the connection between the input and output ends of the main control module and the enable module, as long as the enable end is pulled high, the input and output ends will be pulled high, and through the connection, the input and output ends will be pulled high again, so that after the trigger signal of the clock chip is interrupted, the main control module will not be powered off and will remain in the power-on state; after the clock chip transmits the trigger signal, the main control module is powered on through the enable end. As long as the input and output ends and the enable end are not disconnected and the level of the input and output ends is not lowered, the main control module will always be in the power-on state.

[0035] In an exemplary embodiment, the system further comprises: when the input and output terminals are pulled low, the main control module is shut down.

[0036] It should be noted that after the clock chip transmits the trigger signal, the main control module is powered on through the enable end. As long as the input / output end and the enable end are not disconnected and the level of the input / output end is not lowered, the main control module is always in the powered-on state. Therefore, when the main control module needs to be shut down, it is only necessary to pull down the input / output end, or disconnect the input / output end from the enable end. However, in order to maintain the power-on state normally at the next set power-on time, it is generally chosen to shut down the main control module by pulling down the input / output end at a non-RTC trigger time.

[0037] According to another embodiment of the present invention, a method for controlling the power-on of a main control module is provided, and the method is run in the above system. Figure 2 is a flow chart of a method for controlling power-on of a main control module according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0038] Step S202, receiving a trigger signal sent by a clock chip, wherein the trigger signal is a signal that triggers the clock chip to send when a trigger time arrives;

[0039] Step S204, sending an enable signal to the main control module through the field effect tube to control the main control module to power on, wherein the enable signal is a signal sent to the main control module after the field effect tube is turned on by the trigger signal.

[0040] Through the above steps, the problem of high static power consumption of the vehicle-mounted equipment is solved, and the effect of realizing the automatic power on and off function of the vehicle-mounted equipment with extremely low static power consumption is achieved, thereby reducing the static power consumption and the cost at the same time.

[0041] The execution subject of the above steps may be a computer, a vehicle-mounted terminal, etc., but is not limited thereto.

[0042] In an optional embodiment, an enable signal is sent to the main control module through a field effect tube to control the main control module to power on, including: sending the enable signal to the enable end of the main control module through the field effect tube so that the enable end of the main control module is pulled high to control the main control module to power on.

[0043] Obviously, the above-described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] The present invention will be specifically described below in conjunction with embodiments:

[0045] Figure 3 This is a simplified block diagram of a preferred method for controlling the power-on of a main control module according to an embodiment of the present invention, as shown in the figure:

[0046] The clock chip and the main control module are connected through an external circuit. When the interrupt trigger time set in the clock chip arrives, the interrupt pin of the clock chip is triggered to send a trigger signal to the external circuit. The trigger signal controls the external circuit to conduct and pull up the enable terminal of the main control module, thereby turning on the main control module on time.

[0047] Figure 4 1 is a schematic diagram of the structure of the preferred control system for powering on the main control module according to an embodiment of the present invention. In this embodiment, the clock chip adopts the RTC chip, and the power supply device adopts the power supply of the vehicle-mounted device (corresponding to Figure 4 VBAT). Figure 4 As shown, the system includes: a main control module, an RTC chip and an external circuit; the main control module is a simplified topology of the entire module, including a power supply, a SOC chip and related peripherals, etc., because this embodiment only uses the power enable part (corresponding to Figure 4 EN part) and the input and output terminals of the main control module (corresponding to Figure 4 IO part in ), other irrelevant parts are in Figure 4 The RTC chip module requires the use of the power supply pin (corresponding to the VCC part in the figure) and the interrupt pin of the RTC chip (corresponding to Figure 4 The battery part is used to power the RTC chip without an external power supply, and the interrupt pin is used to send a signal to the outside after the trigger time is reached; VBAT is the power supply for the vehicle-mounted equipment, which comes from the car battery.

[0048] When VBAT power supply is available, the vehicle-mounted device, i.e., the main control module, has the power required for operation; when the time reaches the interrupt trigger time set in the register of the RTC chip, the interrupt pin ( Figure 4 IPQ) is triggered and outputs a low level. The RTC chip used in this embodiment is a low-level trigger output, which can actually be a high-low level or other output form; the low level turns on the field effect tube, and VBAT enables the power supply of the main control module after voltage regulation ( Figure 4 After the main control module is powered on, the input and output terminals (EN part) of the main control module are pulled high. Figure 4 IO), to ensure that the power supply will not be turned off after the RTC trigger time ends; then the main control module works normally; when it needs to be shut down, the main control module can be shut down by pulling down IO at any non-RTC trigger time.

[0049] Figure 5 1 is a flow chart of a preferred method for controlling a main control module to power on a system according to an embodiment of the present invention. As shown in the figure, the flow chart includes the following steps:

[0050] S502, the clock chip runs normally under the power supply of the battery, wherein the clock chip is powered by an external battery to ensure that the clock chip can run normally;

[0051] S504, determine whether the time reaches the trigger time set by the clock chip; if the time reaches the trigger time set by the clock chip, execute S506; if the time does not reach the trigger time set by the clock, execute S502;

[0052] S506, the clock chip outputs a trigger signal;

[0053] It should be noted that the interrupt trigger time can be set in the register in the clock chip. When the time reaches the set trigger time, the interrupt pin of the clock chip is triggered and outputs a low level to the outside. The clock chip can also output other forms of signals to the outside, which is not limited in the present invention.

[0054] For example, the clock chip is set to transmit a trigger signal to the external circuit once an hour, and each trigger time is 3 seconds. If the timing reaches one hour, the clock chip sends a low level to the outside through the interrupt pin, and the low level is maintained for 3 seconds. After 3 seconds, the interrupt pin stops sending the low level and sets the low level to a high level.

[0055] S508, the power supply of the main control module is enabled, the main control module is started, and the low level output by the clock chip turns on the field effect transistor in the external circuit. After the field effect transistor is turned on, the power supply of VBAT powers on the enable terminal of the main control module, so that the main control module is started;

[0056] S510, the main control module outputs the power supply HOLD to ensure that the main control module does not lose power after the clock chip trigger time ends.

[0057] It should be noted that since the trigger time 3 of the clock chip can only be maintained for 3 seconds, after 3 seconds, the field effect tube is no longer turned on. At this time, the enable end of the main control module cannot be controlled by the field effect tube to continue to be pulled high. In order to prevent the main control module from being affected by the stop triggering of the clock chip, after the main control module is started, the input and output ends of the main control module will be pulled high, and the input and output ends are connected to the enable end. The input and output ends can pull up the enable end, and the enable end remains powered on to ensure that after the trigger time of the clock chip ends, the enable end will not lose power, so that the main control module is still in the power-on state.

[0058] S512: The main control module operates normally.

[0059] The main control module is always in the power-on state, so the main control module can operate normally. When the main control module needs to be shut down after the work is completed, it can be shut down by pulling down the input and output terminals when the clock chip is in the non-triggering moment. When the clock chip reaches the next triggering moment, the main control module can be restarted.
