Description
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 used, and higher requirements are also put forward on the power of an automobile generator and the capacity of a storage battery. In most automobiles, when ignition is performed, power supply of a storage battery is needed to start ignition, so that the protection of the electric quantity of the storage battery from loss becomes an indispensable consideration in the control design of an automobile body when an engine of the automobile is not in operation.
At present, by designing an Electronic Control Unit (ECU) working state and a sleeping state, after a vehicle power supply is OFF, when a whole vehicle sleeps, each controller enters a low power consumption state, so that dark current of the real vehicle is reduced, and awakening of an awakening source supported by the ECU is supported.
However, since the remote monitoring terminal (T-BOX) is still connected to the network after sleeping, under the following conditions, the dark current is rapidly increased to more than several tens of milliamperes, so that the dark current of the whole vehicle exceeds the standard, and the whole vehicle is easily fed. Especially for the coming of 5G network, the power consumption of 5G module is much larger than that of 4G module, and the following current consumption is more serious.
Problem scenario 1: after the vehicle enters the dormancy in the state that the vehicle power is OFF, under the condition of no network, the T-BOX searches for 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 owner parks the vehicle in the area for a long time, dark current consumed may be increased for a long time in the conventional sleep-standby mode.
Problem scenario 2: after the vehicle enters the sleep state with the power supply of the vehicle in the OFF state, 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 frequency is set differently by the network side at different places), and the current consumption is increased under the conventional sleep standby mode.
Problem scenario 3: when the power supply of the vehicle is OFF, the whole vehicle enters the dormancy 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 adjacent cell in the scene, and when a switching condition is met, the T-Box is switched to the adjacent cell for registration; if the adjacent cell can not complete the registration, the cell will be selected back to the original cell, causing ping-pong handover and increasing the current consumption. If the owner parks the vehicle in the area for a long time, the dark current consumed is increased for a long time.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In the present examples, "first", "second", etc. are used for distinguishing different objects, and are not used for describing a specific order or sequence.
Example one
Fig. 1 is a schematic flow chart of a method for power management optimization 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 to perform software periodic awakening T-Box, supporting awakening of all awakening sources, and setting the running state of a functional module corresponding to the sleep mode;
s3: after a first preset time, if the vehicle is awakened without an awakening source in the sleep mode, the vehicle enters a deep sleep mode, software is set to periodically awaken the T-Box, the awakening source outside the vehicle is closed, and the running state of a functional module corresponding to the deep sleep mode is set;
s4: and after the vehicle passes through a second preset time, the vehicle enters a closing mode without awakening the awakening source in the deep sleep mode, has no functions, only supports the hard line awakening source and the CAN line awakening source, and sets the running state of the functional module corresponding to the closing mode.
In this embodiment, the functional architecture of the T-Box power management is mainly to collect and classify the wake-up source, and sort and classify the power consumption and the mode thereof. Common awakening sources mainly comprise a hard line awakening source, a CAN line awakening source, a system awakening source and an external awakening source, and the priority of the awakening sources is designed to sequentially rise according to the power consumption condition.
The awakening source priority is as follows from high to low in sequence:
1. hard-wired wake-up source: IGN ON or ACC; the CAN line wakes up the source.
2. A system wake-up source: the hardware RTC.
3. An off-board wake-up source: SMS, IP, BLE, etc. remote wake-up source or near field wake-up source.
In this embodiment, 4 power modes are designed: working mode, sleep mode, deep sleep mode, and off mode. The current consumption is in turn reduced. The operation states of the main functional modules in each mode are as follows:
TABLE 1
Wherein:
the CAN function module is responsible for CAN communication in the vehicle, CAN dormancy supports CAN bus message awakening, and CAN be set to be awakened by a specific CAN message or all CAN messages CAN be awakened.
The RTC is a hardware timing module and supports setting a corresponding timer, and enters the dormancy again after the timing task is completed after the T-BOX is awakened once.
The MCU supports power wake-up from a hard wire when sleeping, and simultaneously receives remote instructions from an NAD module (networking module) and near-field instruction processing from a BLE module.
The NAD is a vehicle wireless network networking module and supports 2G/3G/4G/5G network connection. T-BOX searches for the net, after the network side pages T-BOX with the fixed frequency, T-BOX logs on the net periodically and is all finished by the module, it is the biggest part of current consumption in T-BOX apparatus too. When the NAD is in a dormant state, remote information such as SMS (short message 2G) instruction and IP (3G/4G) instruction wake-up is supported, and during the period, network searching and network login operation are carried out periodically. The NAD does not support remote wake-up after being turned off, nor does it support network searching, networking operations, and periodic network entry operations.
BLE is bluetooth module, supports the bluetooth instruction to awaken up during dormancy, does not support the bluetooth instruction to awaken up after closing.
GPS is a vehicle positioning module, and only T-BOX is awakened when in working mode.
In this embodiment, the wake-up sources supported by each power mode are designed as the following table 2 in combination with table 1:
TABLE 2
| Wake-up source | Hard-wired wake-up source | CAN line awakening source | System awakening source (RTC) | External wake-up source (SMS, IP, BLE) |
| Mode of operation | Has been in the wake-up state | Has been in the wake-up state | Has been in the wake-up state | Has been in the wake-up state |
| Sleep mode | Supporting wake-up | Supporting wake-up | Supporting wake-up | Supporting wake-up |
| Deep sleep | Supporting wake-up | Supporting wake-up | Supporting wake-up | Turn off the wake-up source |
| Off mode | Supporting wake-up | Supporting wake-up | Turn off the wake-up source | Turn 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, which details the implementation process of the method:
1. the working mode is as follows: the mode is a normal mode, the T-Box is in a full-function state, all applications can respond, the power consumption current of the mode is the highest, and the working current is usually hundreds of milliamperes.
2. A sleep mode: in the mode, the T-BOX is in a monitoring mode, the MCU, the NAD, the CAN and the BLE all enter a sleep state, and corresponding wake-up source information is monitored; closing the GPS module; the RTC starts to time and judges the vehicle state. Defaulting that there is no wake-up source in the sleep mode for a first preset time (e.g., 7 days in fig. 2), determining that the vehicle is in an infrequent use state (i.e., the vehicle owner has not used the vehicle for at least 7 consecutive days), and entering a next deep sleep mode;
the first preset time is vehicle state judgment time, defaults to 7 days, is a configurable parameter and can be adjusted according to actual conditions of dark current consumed during network searching and network paging of the T-BOX.
The timing service system comprises a Real Time Clock (RTC) timing service support module, a timing service module, a T-BOX (T-BOX) module, a timing service module, a timer module and a timer module, wherein the RTC timing service support timing duration timing can be set in a sleep mode, if the timing service exists, the periodical awakening is supported, the RTC timing awakening frequency is a first preset period, the default time is 4 hours (the first preset period can be matched, and the RTC timing awakening frequency can be designed according to current consumed by the timing service), so that the timing service such as real vehicle state is uploaded to a background regularly after the power supply gear of a real vehicle is OFF.
As shown in table 2, all wake-up source wakeups are supported in sleep mode. The NAD operating system (networking module) and limited programs are running to ensure wake-up functionality, but other applications are shut down for low power consumption, typically at several milliamps.
Wherein, the T-BOX keeps online in the sleep mode and also supports services such as remote and Bluetooth.
3. Deep sleep mode: when the sleep mode life cycle is finished (namely the first preset time is up), the T-Box enters a deep sleep mode, and the NAD module and the BLE module are further turned off, so that the current consumption is reduced. The RTC timing continues.
And judging the state of the vehicle again, and if the default time lasts for a second preset time (such as 5 days in fig. 2) without a wake-up source (such as table 2) in the deep sleep mode, the vehicle is considered to be in a long-term non-service state (i.e., the vehicle owner has not used the vehicle for at least 12 consecutive days), and then enters the next state (i.e., the off state), the RTC timed task timing periodic wake-up T-BOX is supported during the period, 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, in this mode, a hard line wake-up source, a CAN line wake-up source, and a system wake-up source are supported, and the NAD is not powered, and at this time, the SMS and IP channels are disabled, and remote wake-up is not supported, and the current is 1 mA.
The T-BOX is not on-line in the deep sleep mode, the required functions are supported only when the RTC is timed out and the timing task is started, and the T-BOX returns to the deep sleep mode after the timing task is finished.
4. An off mode: further, RTC timing is turned OFF, any timing task is not supported, the whole system is in an OFF state and has no function, and only the hard line wake-up source and the CAN line wake-up source are responded (for example, a driver locally opens a door to trigger bus CAN signals, or locally ignites to trigger the wake-up of the hard line power signals).
