Description

Power management optimization method and device based on remote monitoring module
Technical Field
The invention belongs to the technical field of power management, and particularly relates to a power management optimization method and device based on a remote monitoring module.
Background
At present, more and more automobile electric devices are provided, and higher requirements are also put on the power of an automobile generator and the capacity of a storage battery. When most automobiles are ignited, the storage battery is required to supply power to start ignition, so that the protection of the electric quantity of the storage battery from losing is an indispensable consideration in the automobile body control design under the condition that the engine of the automobile is not operated.
At present, by designing the working state and the dormant state of an electronic control unit (Electronic Control Unit, ECU), after a vehicle power supply is OFF, each controller enters a low-power consumption state after the whole vehicle is dormant, the dark current of the real vehicle is reduced, and the wake-up source supported by the ECU is supported to wake up.
However, because the remote monitoring terminal (T-BOX) remains connected to the network after being dormant, under the following circumstances, the dark current can be rapidly increased to more than tens of milliamperes, so that the dark current of the whole car exceeds the standard, and the feeding of the whole car is easily caused. Particularly for the coming of 5G networks, the power consumption of the 5G module is far greater than that of the 4G module, and the current consumption described below is more serious.
Problem scenario 1: after the whole vehicle enters dormancy under the OFF state of the vehicle power supply, under the condition of no network, the T-BOX searches the network with a certain frequency (the network searching period depends on the design of the T-BOX side), and the current consumption is increased. If the vehicle owner parks the vehicle in this area for a long period of time, the consumed dark current is increased for a long period of time in the conventional sleep standby mode.
Problem scenario 2: after the whole vehicle enters dormancy in the state that the power supply of the vehicle is OFF, the network is fixed, the network side pages the T-BOX at a fixed frequency, the T-BOX periodically logs in the network (the period depends on the network side, and the network side sets different frequencies at different places), and the current consumption caused by the conventional dormancy standby mode is increased.
Problem scenario 3: after the whole vehicle enters dormancy when the power supply of the vehicle is in an OFF state, an available network exists, and a ping-pong switching scene is realized. In a conventional sleep standby mode, the T-Box still measures the neighbor cells in the scene, and when the switching condition is met, the T-Box is switched to the neighbor cells for registration; if the neighbor cell cannot complete registration, the original cell is selected back, so that ping-pong handover is caused, and the current consumption is increased. If the vehicle owner parks the vehicle in this area for a long period of time, the consumed dark current increases for a long period of time.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
In the examples of the present invention, "first," "second," etc. are used to distinguish between different objects, and are not used to describe a particular order or sequence.
Example 1
Fig. 1 is a schematic flow chart of a power management optimization method based on a remote monitoring module according to an embodiment of the present invention, where the method shown in fig. 1 includes the following steps:
s1: when the vehicle is in a working mode, the T-Box is in a full-function state, and all applications can respond;
s2: when the vehicle is in a sleep mode, setting and carrying out software periodic wake-up T-Box, supporting wake-up of all wake-up sources, and setting a functional module running state corresponding to the sleep mode;
s3: after the vehicle passes through a first preset time, a wake-up source in a non-sleep mode wakes up, and then enters a deep sleep mode, a software periodically wakes up a T-Box, an off-vehicle wake-up source is closed, and a functional module running state corresponding to the deep sleep mode is set;
s4: after the second preset time passes, the vehicle wakes up the wake-up source in the no-depth sleep mode, and then enters the shutdown mode, and the vehicle is nonfunctional, only supports the hard wire wake-up source and the CAN wire wake-up source, and sets the functional module running state corresponding to the shutdown mode.
In this embodiment, the functional architecture of T-Box power management is mainly to collect and classify wake-up sources, and sort their power consumption and modes. The common wake-up source mainly comprises a hard wire wake-up source, a CAN wire wake-up source, a system wake-up source and an off-board wake-up source, and the priority of the wake-up source is designed to be sequentially increased according to the power consumption condition.
The wake-up source priority is sequentially as follows from high to low:
1. hard-wire wake-up source: IGN ON or ACC; the CAN line wakes up the source.
2. The system wakes up the source: hardware RTC.
3. An off-board wake-up source: SMS, IP, BLE, etc. a remote wake-up source or a near field wake-up source.
In this embodiment, 4 power modes are designed: the device comprises a working mode, a dormant mode, a deep dormant mode and a closing mode. The current consumption decreases in turn. The main functional module operating states in each mode are as follows in table 1:
TABLE 1
Wherein:
the CAN function module is responsible for CAN communication in the vehicle, and CAN dormancy supports CAN bus message awakening, and CAN be set to be specific CAN message awakening or all CAN messages CAN be awakened.
The RTC is a hardware timing module, supports to set a corresponding timer, and enters dormancy again after finishing timing tasks after timing time reaches the wake-up T-BOX once.
The MCU is dormant to support power wakeup from a hard wire, and simultaneously receives remote instructions from an NAD module (networking module) and near-field instruction processing from a BLE module.
NAD is a vehicle wireless network networking module supporting 2G/3G/4G/5G network connection. After the T-BOX searches the network and the network side pages the T-BOX at a fixed frequency, the periodical login of the T-BOX to the network is completed by the module, and the module is also the largest part of current consumption in the T-BOX equipment. The NAD dormancy supports remote information such as SMS instruction (short message 2G) and IP instruction (3G/4G) to wake up, and network searching and periodical network logging operations can be performed during the period. After the NAD is closed, remote wakeup is not supported, and network searching, networking operation and periodical network logging operation are not supported.
BLE is bluetooth module, supports bluetooth instruction awakening during dormancy, does not support bluetooth instruction awakening after closing.
The GPS is a vehicle positioning module and is awakened only when the T-BOX is in the working mode.
In this embodiment, the wake-up sources supported by each power mode are designed in conjunction with table 1 as follows in table 2:
TABLE 2
Awakening source Hard wire wake-up source CAN line wake-up source System wake-up source (RTC) Outside awakening source (SMS, IP, BLE)
Mode of operation Has been in a wake-up state Has been in a wake-up state Has been already atIn the wake-up state Has been in a wake-up state

Off mode Supporting wake-up Supporting wake-up Turning off the wake-up source Turning off the wake-up source
Example two
Fig. 2 is a schematic flow chart of another power management optimization method based on a remote monitoring module according to an embodiment of the present invention, and details of a method implementation process are described:
1. working mode: the mode is a normal mode, the T-Box is in a full function state, and all applications can respond, and the power consumption current of the mode is highest, and the working current is usually hundreds of milliamperes.
2. Sleep mode: in this mode, the T-BOX is in a monitor mode, MCU, NAD, CAN, BLE enters a sleep state, and monitors the corresponding wake-up source information; closing the GPS module; and starting the RTC timing, and judging the state of the vehicle. Defaulting to a first preset time (for example, 7 days in fig. 2) to judge that the vehicle is in a state of not being used frequently (i.e. the vehicle owner has not used the vehicle for at least 7 consecutive days) when the wake-up source in the sleep-free mode is not used, and entering the next deep sleep mode;
the first preset time is vehicle state judging time, defaults for 7 days and is a configurable parameter, and the first preset time can be adjusted according to actual conditions of dark current consumed during T-BOX network searching and network paging.
The timing duration timing supporting the RTC timing service can be set in the sleep mode, if the timing service exists, the periodic wake-up T-BOX is supported, the RTC timing wake-up frequency is a first preset period, and the default time is 4 hours (the first preset period can be matched and can be designed according to the current consumed by the timing service) so as to support the timing service such as uploading the real vehicle state to the background at regular time after the power supply gear of the real vehicle is OFF.
As shown in table 2, all wake sources are supported to wake in sleep mode. The NAD operating system (networking module) and limited programs are running to ensure wake-up functionality, but other applications are off for low power consumption purposes, typically a few milliamps.
The T-BOX keeps networking online in the sleep mode, and also supports services such as remote service, bluetooth service and the like.
3. Deep sleep mode: when the sleep mode life cycle is finished (i.e. the first preset time is up), the T-Box enters a deep sleep mode, and further closes the NAD module and the BLE module, so that the current consumption is reduced. The RTC timer continues.
And (3) judging the state of the vehicle again, defaulting to a second preset time (5 days in fig. 2) and enabling the vehicle to wake up the T-BOX periodically after the vehicle is in a long-term no-service state (i.e. the vehicle owner has not used the vehicle for at least 12 continuous days) if the vehicle is in the wake-up source (shown in table 2) in the no-deep sleep mode, wherein the period supports the RTC timing task to wake up the T-BOX periodically, and the polling frequency period is a second preset period (such as 6 hours).
The second preset time and the second preset period can be designed according to the current consumed by the timing service.
As shown in table 2, the hard wire wake-up source, CAN wire wake-up source and system wake-up source are supported in this mode, the NAD is unpowered, the SMS, IP channels are disabled, remote wake-up is not supported, and the current < = 1mA.
The T-BOX is not on-line in the deep sleep mode, only supports the required functions when the RTC times, the timing task is started, and returns to the deep sleep mode after the timing task is ended.
4. Shut-down mode: further closing RTC timing, not supporting any timing tasks, enabling the whole system to be in an OFF state, having no function, and only responding to a hard wire awakening source and a CAN wire awakening source (such as a driver local door opening trigger bus CAN signal or local ignition trigger hard wire power signal awakening).
