Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
Referring to fig. 1 and 2, the positioning and tracking device provided by the invention comprises a master control module, a slave control module, a battery, a communication module, a GPS positioning module and one or more sensing modules. The slave control module is connected with a GPS positioning module, a sensing module and a battery; the master control module is connected with a communication module, a slave control module and a battery. The sensor module in fig. 1 is a sensor in a low power consumption operation mode, and can operate with low power consumption for a long time, and an acceleration sensor is taken as an example for description below. The second embodiment in fig. 2 adds a sensing module in a power down mode to the first embodiment in fig. 1. Such sensing modules start to operate by being started periodically or being powered on from the control module. The following description will take the temperature and humidity sensing module as an example.
The positioning and tracking device provided by the invention comprises two control modules, a battery, a GPRS communication module, a GPS positioning module, a sensor module and other peripheral equipment. One of the two control modules is a master control module, and the other control module is a slave control module; the master control module is respectively connected with the GPRS communication module, the slave control module and the battery and is used for sending monitoring data; the slave control module is respectively connected with the GPS positioning module, the temperature and humidity sensing module, the acceleration sensing module and the battery and used for monitoring and acquiring temperature and humidity, acceleration, the battery and position data.
The master control module and the slave control module are processors with different working frequencies. The slave control module selects a processor with a relatively low frequency. Compared with a high-frequency processor, the low-frequency processor is used for monitoring the data processing process, so that power is saved. The processor with high working frequency is used as a main control module and is only responsible for sending monitoring data. In the invention, the control module preferably adopts a PIC series singlechip, and the working frequencies of the master control module and the slave control module are respectively 32MHz and 8 MHz. When data interaction is performed between the master control module and the slave control module, the master control module and the slave control module can be mutually awakened in an interrupt mode or a polling mode. The invention prefers the interrupt mode, which has better power saving effect compared with the polling wake-up mode, but the polling mode is selected according to the service requirement, which can well achieve the purpose of power saving. Of course, the wake-up of the control module requires an acknowledgement mechanism: the data can be transmitted only when the other party is confirmed to be capable of receiving the data, otherwise, the data is easy to lose.
For the selection of the peripheral equipment of the control module, the same or similar working frequency needs to be managed by the same control module. In the invention, the slave control module controls the GPS positioning module, the temperature and humidity sensing module and the acceleration sensing module which have relatively low working frequency. And the main control module controls the GPRS communication module with higher working frequency. In general, the longer the control module enters the sleep mode, the more obvious the power saving effect is. According to the invention, when the slave control module needs to transmit data when the sensor detects data or the data of the battery are abnormal, the slave control module enters the working mode. After the data transmission is finished, the main control module enters a sleep mode again. For the master control module with high frequency, the master control module is only responsible for data transmission, so that the master control module with higher frequency can be ensured to be in a sleep state for more time, and the loss of electric energy is reduced.
The following describes the operation flow of the positioning and tracking device and the specific implementation steps of the power saving method thereof with reference to fig. 3.
Step 1: and initializing the positioning and tracking device and configuring working parameters. The positioning and tracking device needs to be initialized first. And after the master control module and the slave control module are powered on, initializing. In the initialization process, working parameters of the master control module and the slave control module need to be set, and corresponding parameters are synchronized to corresponding configured peripheral equipment. The set working parameters comprise related parameters such as a battery, a temperature and humidity sensor, an acceleration sensor and the like. Such as a battery voltage change warning value, a temperature and humidity warning value, an acceleration warning value, and the like. And when the detected parameter exceeds the early warning value, the slave control module carries out corresponding processing. Through setting working parameters, the early warning value is set to be high, so that the slave control module can work under most conditions without waking up the master control module. However, the setting of the early warning value should be adjusted according to the service requirement, so that the main control module can be awakened in time when the working parameters change. Therefore, the setting of the early warning value needs to make the main control module in a dormant state for more time on the premise of ensuring the service requirement, so that the electric energy loss is reduced.
Step 2: the master control module and the slave control module enter a sleep mode, the communication module and the GPS positioning module enter a power-off mode, and the sensing module enters a low-power-consumption working mode or a power-off mode.
And step 3: the sensing module wakes up the slave control module under a preset condition, judges whether the master control module needs to be woken up or not after the slave control module is woken up, and when the master control module needs to be woken up, the slave control module wakes up the master control module and enables the GPS positioning module to enter a working mode, then reads the position information of the GPS positioning module, sends the position information to the master control module, finally returns to a sleep mode and enables the GPS positioning module to enter a power-off mode, and then enters step 4; when the main control module is judged not to be required to be awakened, returning to the step 2;
and 4, step 4: and (3) after the main control module is awakened, enabling the communication module to enter a working mode, sending out the position information from the GPS positioning module through the communication module, then returning to a sleep mode, powering off the communication module, and returning to the step 2.
Specifically, after the initialization is completed, the master control module and the slave control module power off the GPS positioning module, the GPRS communication module and the temperature and humidity sensing module. And the acceleration sensing module enters a low-power mode, and simultaneously the master control module and the slave control module enter a sleep mode.
The acceleration sensing module has two working modes of low frequency and normal. Normally, the acceleration sensing module is in a low power mode for data collection, which can reduce power consumption. When the monitored acceleration data is abnormal compared with the configured working parameters, the acceleration sensing module is rapidly switched from the low-power mode to the normal mode, and the slave control module in the sleep mode is awakened in an external interrupt mode. And reading the acceleration data from the control module and comparing and analyzing the acceleration data with the working parameters configured in the initial process. If the acceleration value is within the normal early warning range, the acceleration sensing module is switched to a low power consumption mode, and the slave control module enters a sleep mode. If the acceleration value exceeds the early warning value, the slave control module needs to power on the GPS positioning module after the acceleration sensing module is switched to a low power consumption state. The GPS positioning module adopts a power-on working mode, can work only by controlling power-on by the slave control module, and is in a power-off state at other time, so that the consumption of a battery is reduced. The GPS positioning module acquires the current position data of the positioning and tracking device and sends the current position data to the slave control module. And after the slave control module receives the current position data, the GPS positioning module is powered off, and the master control module is awakened in an interrupted mode. After the master control module is awakened, the slave control module sends the position data and then enters a sleep mode.
And for data acquisition of the temperature and humidity sensing module, the slave control module works in a polling mode. And (3) reading temperature and humidity data at regular time by using an internal clock, and entering a sleep mode when the data is not read. The timer is processed in an internal interrupt mode, regularly monitors whether a set reading period is reached, and wakes up the slave control module after the set reading period is reached. And reading temperature and humidity data from the slave control module, analyzing according to a set temperature and humidity early warning value, and judging whether the master control module needs to be awakened or not. If not, the main control module continues to be in the sleep mode. And if the GPS positioning module needs to be awakened, the slave control module powers on the GPS positioning module. The GPS positioning module acquires the current position data of the positioning and tracking device and sends the current position data to the slave control module. After the slave control module receives the data, the GPS positioning module is powered off, and simultaneously the master control module is awakened in an interrupted mode.
After the slave control module is awakened, the voltage and the electric quantity of the battery are required to be detected at regular time. The monitoring process is similar to that of the temperature and humidity sensing module, and is not repeated here. It should be noted that, when the slave control module monitors that the electric quantity of the battery is low, the time interval of the timing monitoring of the temperature and humidity sensing module is increased. This ensures that the device can reduce power consumption at lower voltages, thereby monitoring the condition of the entire tracking device for a longer period of time.
After the master control module is awakened and receives the position information sent by the slave control module, the GPRS communication module is powered on at the same time. The GPRS communication module and the GPS positioning module work in the same mode, and a power-on working mode is adopted. The GPRS communication module can start to work only when the main control module is awakened and then the GPRS communication module is powered on. And the GPRS communication module transmits the position data to a remote equipment tracking and monitoring center through a wireless network. After the GPRS communication module finishes data transmission, the main control module powers off the GPRS communication module and enters a sleep mode.
The power consumption of the battery is different due to different operating conditions of the modules. The following cases are classified according to the power consumption of the battery: the two control modules are in working states, the peripheral equipment is also in a working state, and the power consumption current of the battery can exceed 100mA or even is higher; when only two control modules work and the peripheral does not work, the power consumption current can exceed 40 mA; when only one 8M slave control module works, the power consumption current is only about 10 mA; when the two control modules enter the sleep mode, the power consumption current does not exceed 1 mA. Therefore, in order to avoid the simultaneous operation of the two control modules, strict logic operation needs to be performed in the 8M slave control module, and the 32M master control module is ensured to be in the sleep mode for a long time, thereby achieving a better power saving effect.
In the invention, after the control module enters the sleep mode, the longer the time of the sleep mode, the more obvious the effect of power saving is. And the corresponding peripheral equipment configured by the control module enters a low-power consumption or sleep or power-off mode. In the sleep mode, the slave module may be woken up by an internal clock or an external interrupt. And the slave control module after being interrupted and awakened only needs to carry out simple and quick logic judgment, and returns to the sleep mode immediately if the slave control module does not need to work. And if the work is needed, continuing to enter the sleep mode after the position information is processed. And the main control module enters a sleep mode after the position information is sent. Therefore, the invention can lead the positioning and tracking device to have the function of saving electricity and ensure the long-time monitoring work.
In summary, the positioning and tracking device provided by the invention adopts double control modules, and configures the peripheral equipment to the control modules according to the working frequency. The master control module controls the peripheral equipment with higher frequency and ensures that the peripheral equipment is in an idle or sleep mode under the condition that the master control module does not need to work. And the slave control module is awakened to transmit data only when the data of the sensor module or the battery is abnormal. And other times in idle or sleep mode. Compared with a positioning and tracking device of a single control module, the double control module adopted by the invention does not need to continuously access and detect data; and peripheral equipment is distributed to the control module according to the working frequency, so that the state that the control module continuously runs at the highest frequency is avoided. The invention prolongs the time that the control module is in the sleep mode as far as possible by setting the working mode of the peripheral equipment, obviously reduces the total energy consumption of the positioning and tracking device and greatly prolongs the effective working time of the device.
The above has described the positioning and tracking device with power saving function and the power saving method thereof provided by the present invention in detail. Any obvious modifications to the invention, which would occur to those skilled in the art, without departing from the true spirit of the invention, would constitute a violation of the patent rights of the invention and would carry a corresponding legal responsibility.
