Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Under the prior art, the bit number of sampling and the demodulation algorithm both need to consume larger calculation amount, and the corresponding required power supply is very large, and larger heat can be generated, so that the temperature of the receiver is too high, and the normal operation is difficult.
In view of this, the present invention provides a method for receiving electromagnetic signals, please refer to fig. 1, fig. 1 is a flow chart of an embodiment of the method for receiving electromagnetic signals of the present invention, in this embodiment, the method for receiving electromagnetic signals includes steps S110 to S130, which specifically include the following steps:
s110: at least one ambient temperature is obtained.
S120: and if the ambient temperature of each periphery is greater than a preset threshold value, processing the received electromagnetic signals according to the first working mode.
S130: and if the at least one ambient temperature is less than or equal to the preset threshold value, processing the received electromagnetic signals according to the second working mode.
Wherein the complexity of the first demodulation algorithm of the first working mode is smaller than the complexity of the second demodulation algorithm of the second working mode; and/or, the first working period of the first working mode comprises a pause working time. That is, the first demodulation algorithm is a low-complexity demodulation algorithm, and the second demodulation algorithm is a high-complexity demodulation algorithm.
The ambient temperature of the receiver is periodically detected and a plurality of temperature detection points may be provided in the receiver to detect the ambient temperature at different sampling locations of the receiver. When multiple ambient temperatures are acquired, it may refer to ambient temperatures at the same point in time but at different acquisition locations within an acquisition cycle; or the ambient temperature at different time points in the same detection period and at the same acquisition position; or the ambient temperature at different time points and different acquisition positions in the same detection period.
The operating cycle may include a normal operating time and a pause operating time. The second operation period of the second operation mode may be considered as excluding the pause operation time in comparison with the first operation mode, i.e. the pause operation time in the second operation period is 0.
It will be appreciated that the second mode of operation is a normal mode of operation of the electromagnetic signal receiver and the first mode of operation is an energy efficient mode of operation of the electromagnetic signal receiver.
The preset threshold value can be understood as a temperature threshold, and when the ambient temperature of the electromagnetic signal receiver exceeds the temperature threshold, the working temperature of the electromagnetic signal receiver is considered to be too high, and devices are easy to damage, so that energy-saving work is required, and heat generated by the work in the electromagnetic signal receiver is reduced. Specific values of the temperature threshold may be set by those skilled in the art according to actual situations, and are not described herein.
The first and second modes of operation are set for the primary energy consuming device in the electromagnetic signal receiver. It should be understood that there may be one or more devices in the receiver capable of performing the first and second modes of operation, and that there may be a parameter difference between the first and second modes of operation in different devices, specifically set according to the actual situation.
According to the electromagnetic signal receiving method disclosed by the embodiment, the ambient temperature of the receiver is compared with the preset threshold, and if the ambient temperature of each receiver is greater than the preset threshold, the received electromagnetic signals are processed according to the first working mode; if the temperature of at least one surrounding environment is smaller than or equal to the preset threshold value, the received electromagnetic signals are processed according to the second working mode, so that the power consumption of the electromagnetic signal receiver can be controlled, the proper working mode is selected according to the ambient temperature, the service life of the receiver is prolonged, and technical support is provided for miniaturization of the receiver.
The main power consuming components of the electromagnetic signal receiver may include a mixer module and a demodulator module. In some embodiments, if each ambient temperature is greater than a preset threshold, the step of processing the received electromagnetic signal according to the first operation mode includes:
if the ambient temperature of each periphery is greater than a preset threshold value, a mixer module of the receiver mixes the received electromagnetic signals with a first working period, and a demodulation module of the receiver demodulates the mixed electromagnetic signals with a first demodulation algorithm; or alternatively, the process may be performed,
if the ambient temperature of each periphery is greater than a preset threshold, the mixer module of the receiver mixes the received electromagnetic signals in a first working period; or alternatively, the process may be performed,
and if the ambient temperature of each periphery is greater than a preset threshold value, the demodulation module of the receiver carries out modulation processing on the mixed electromagnetic signals by using a first demodulation algorithm.
In some embodiments, if at least one ambient temperature is less than or equal to a preset threshold, the step of processing the received electromagnetic signal according to the second operation mode specifically includes:
if at least one ambient temperature is less than or equal to a preset threshold value, the mixer module of the receiver mixes the received electromagnetic signals with a second working period, and the demodulation module of the receiver demodulates the mixed electromagnetic signals with a second demodulation algorithm.
In some embodiments, the first duty cycle includes a normal operation time and a pause operation time, and the step of mixing the received electromagnetic signal by the mixer module of the receiver with the first duty cycle specifically includes:
in the normal working time of the first working period, the mixer module mixes the received electromagnetic signals and inputs the mixed electromagnetic signals to the demodulation module; during the pause operation time of the first operation period, the mixer module stops operating.
In some embodiments, the step after the mixer module of the receiver mixes the received electromagnetic signal with the first duty cycle further comprises:
after the mixer module completes a first working period, at least one current ambient temperature is obtained; if at least one current ambient temperature is greater than a preset threshold value, prolonging the pause working time in the first working period to obtain a new first working period; the mixer module mixes the received electromagnetic signal with a new first duty cycle.
The pause time of the first duty cycle may vary according to the duration of the ambient temperature being greater than the preset threshold, the longer the pause time of the first duty cycle.
It should be further noted that, because there may be an error in detecting the temperature, a plurality of ambient temperatures may be collected, and when the plurality of ambient temperatures are all greater than the preset threshold, the first operation mode is executed; if at least one ambient temperature is less than or equal to a preset threshold (the condition that the temperature detection module is failed has been excluded), a second operation mode is performed.
However, after the first operation mode is started, in the energy-saving operation mode, the ambient temperature of the receiver gradually decreases, and thus, a situation may occur in which a part of the ambient temperature is greater than a preset threshold and a part of the ambient temperature is less than or equal to the preset threshold. At this time, the first operation mode may be continuously performed until all the ambient temperatures are less than or equal to the preset threshold, so as to avoid repeated switching between modes.
The electromagnetic signal receiving method of the present invention is exemplified as follows:
1. the working mode control module periodically reads the ambient temperature detected by the temperature detection module and records the ambient temperature in one acquisition period as T1, … … and Tn.
2. Comparing T1, … … and Tn with a preset threshold value T0, if the T1, … … and Tn are smaller than the T0, processing data acquired by the ADC through a high-complexity demodulation algorithm, and entering a data storage module to finish data storage; if the partial value is greater than T0, the data acquired by the ADC is processed by a low-complexity demodulation algorithm and enters a data storage module; meanwhile, the working mode control module controls the main energy consumption devices in the receiver to start to work periodically; wherein, the working time is A0, and the stopping time is U0.
3. The working mode control module continues to periodically read the ambient temperature T1', … …, tn' of the temperature detection module, if the partial value is still greater than T0, the working time of the main energy-consuming device is kept at A0 under the condition of adopting a low-complexity demodulation algorithm, and the stopping time is changed into N x U0 (N=2, 3 … … N); if T1', … … and Tn' are lower than the power control threshold, the high-complexity demodulation algorithm is recovered, and the normal operation of the main energy consumption device is recovered.
4. Repeating the steps 1-3;
5. the temperature of the final receiver will stabilize at T0.
The method of the scheme is used for controlling the power consumption of the electromagnetic signal receiver, the working temperature of the receiver can be controlled to be at the required temperature T0 according to the requirement of the use environment, and the corresponding power consumption is also greatly reduced.
Referring to fig. 2, fig. 2 is a flow chart of another embodiment of the electromagnetic signal receiving method according to the present invention.
After the receiver starts working, detecting and recording the ambient temperature, and subsequently controlling the working mode according to the information; judging whether all the recorded temperature values exceed a temperature threshold. When the temperature value does not exceed the temperature threshold, the received electromagnetic signal is subjected to high-complexity data demodulation processing, whether the pause working time in the working mode is 0 is detected, and if so, the surrounding environment temperature is continuously detected and recorded; if the pause operation time in the operation mode is not 0, the pause operation time of the main energy consumption device is shortened, and then the ambient temperature is continuously detected and recorded.
When the temperature value exceeds the temperature threshold, the received electromagnetic signal is processed by the low-complexity data demodulation module, and after the pause working time of the main energy consumption device is prolonged, the ambient temperature is continuously detected and recorded.
Since low complexity data demodulation requires less computation, power consumption will be reduced; when the temperature value exceeds the temperature threshold, controlling a main energy consumption device in the receiver to start periodic operation (including a pause operation time in an operation period) so as to reduce power consumption and record the operation period; continuously and periodically reading temperature measurement information of the temperature detection module, and continuously prolonging the pause working time of the main energy consumption device under the condition of adopting a low-complexity demodulation algorithm if the temperature still exceeds a temperature threshold; and when the temperature is equal to or lower than the temperature threshold, recovering to adopt a high-complexity demodulation algorithm, and recovering the normal operation of the main energy consumption device.
