Detailed Description
The core of the invention is to provide a method for acquiring the sensor signal, so that the receiving equipment can receive the signal sent by the sensor when the power supply voltage is lower, and the endurance time of the sensor is increased, thereby reducing the replacement frequency of the sensor and improving the user experience; the other core of the invention is to provide a sensor signal acquisition device, equipment and a storage medium, so that the receiving equipment can receive signals sent by the sensor when the power supply voltage is lower, the endurance time of the sensor is increased, the replacement frequency of the sensor is reduced, and the user experience is improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for acquiring a sensor signal according to the present invention, where the method for acquiring a sensor signal includes:
s101: determining the lowest value of the signal intensity of the target sensor transmitting signal which can be sensed by the receiving equipment;
in particular, in view of the technical problems in the background art, in combination with the consideration that the receiving device generally allows a lower limit value of the signal strength range of the received signal to be higher, for example, the sensor generally has a power supply voltage of 3V, the power supply voltage of the sensor gradually decreases as the output voltage value of the power supply battery decreases, and when the value decreases to a critical value of 2.2V, the receiving device does not support receiving the signal emitted by the sensor powered by 2.2V, although the sensor can still emit a signal with a weak strength at the stage of 0-2.2V of the output voltage of the power supply battery, because the value is lower than the lower limit value of the signal strength range of the receiving device for receiving the signal, the sensor must be replaced when the power supply voltage is lower than 2.2V, so as to collect data by using a sensor with sufficient power, which results in a short service life of the sensor, and the replacement frequency of the sensor is increased, which affects the user experience.
Specifically, in order to improve the endurance time of the sensor under the fixed battery capacity, in the embodiment of the present invention, when the supply voltage of the sensor is in the phase of 0 to 2.2V, the receiving device still can allow the receiving device to receive the signal transmitted by the sensor, so that a lower limit value of the signal strength that the receiving device allows to receive needs to be adjusted downward.
It should be noted that the "lowest value of the signal strength of the sensed signal emitted by the target sensor" in this step is the lowest signal strength value actually sensed by the receiving device, regardless of the range of the signal strength allowed to be received set by the receiving device, and the lowest value of the signal strength is usually smaller than the lower limit of the range of the signal strength allowed to be received set by the receiving device.
S102: adjusting the minimum signal intensity of the signals which are allowed to be received by the receiving equipment and transmitted by the target sensor according to the minimum signal intensity value so as to acquire the signals transmitted by the target sensor by using the adjusted receiving equipment;
specifically, after the lowest signal strength value is obtained, in order to extend the signal strength range of the receiving device that allows the receiving device to receive the signal transmitted by the target sensor downward, the minimum signal strength of the receiving device that allows the receiving device to receive the signal transmitted by the target sensor may be adjusted according to the lowest signal strength value in this step, so that the minimum signal strength of the receiving device that allows the receiving device to receive the signal transmitted by the target sensor may be lowered, so that the receiving device may receive the signal transmitted by the sensor when the power supply voltage is low, and the duration of the sensor is increased.
The invention provides a method for acquiring a sensor signal, which is characterized in that the lower limit value of the signal intensity of a receiving device which can normally receive a signal is higher, namely when the sensor sends a signal with weaker intensity due to insufficient power supply voltage, the receiving device cannot receive the signal, so that the lowest value of the signal intensity of the receiving device which can receive the signal sent by a target sensor can be firstly determined, and then the minimum signal intensity of the receiving device which receives the signal sent by the target sensor is adjusted according to the lowest value of the intensity, thereby being beneficial to the lower limit value of the signal intensity of the receiving device which can receive the signal, enabling the receiving device to receive the signal sent by the sensor when the power supply voltage is lower, increasing the endurance time of the sensor, reducing the replacement frequency of the sensor and improving the user experience.
On the basis of the above-described embodiment:
as a preferred embodiment, adjusting the minimum signal strength of the signal transmitted by the target sensor, which is allowed to be received by the receiving device according to the minimum signal strength value, so as to acquire the signal transmitted by the target sensor by using the adjusted receiving device specifically includes:
determining a signal intensity range lower limit value corresponding to the signal intensity lowest value based on a preset conversion relation;
acquiring the lowest signal strength of a signal which is allowed to be received by the current receiving equipment and is transmitted by a target sensor;
judging whether the lower limit value of the signal intensity range is smaller than the lowest signal intensity or not;
and if so, updating the minimum signal intensity of the signals transmitted by the target sensor, which are allowed to be received by the receiving equipment, to the lower limit value of the signal intensity range so as to acquire the signals transmitted by the target sensor by using the updated receiving equipment.
Specifically, after the signal strength minimum value exists, since the signal strength minimum value is the lowest boundary of the signal strength sensed by the receiving device, a signal strength range lower limit value can be obtained by using the signal strength minimum value as a reference, and the signal strength range lower limit value can be used as a data base of a subsequent step.
The preset conversion relationship may be set autonomously, but the lower limit value of the converted signal strength range needs to be greater than the lowest value of the signal strength, which is not limited herein in the embodiments of the present invention.
Specifically, considering that the lower limit of the signal strength range obtained by conversion may not be smaller than the minimum signal strength due to the uncertainty of the lower limit of the signal strength range originally allowed to be received by the receiving device, the preset conversion relationship setting is not appropriate, and the like, at this time, the subsequent steps are not suitable any more, and the service life of the sensor may be reduced, so in order to prevent this, in the embodiment of the present invention, it may be further determined whether the lower limit of the signal strength range is smaller than the minimum signal strength after the lower limit of the signal strength range is obtained, and in the case of being smaller, the step of updating the minimum signal strength allowed by the receiving device to receive the signal transmitted by the target sensor to the lower limit of the signal strength range is performed, so that the implementation of the embodiment of the present invention can ensure that the endurance of the sensor can be increased.
Specifically, after the lower limit value of the signal strength range is obtained, the minimum signal strength of the signal strength range allowed to be received by the receiving device is obtained, so that the minimum signal strength of the signal transmitted by the target sensor allowed to be received by the receiving device is reduced, and therefore when the power supply voltage of the sensor is at a low value (the strength of the corresponding transmitted signal is weak), the receiving device can still receive the signal transmitted by the receiving device, the service life of the sensor is prolonged, the replacement frequency of the sensor is reduced, and the user experience is improved.
As a preferred embodiment, after determining whether the lower limit value of the signal strength range is smaller than the lowest signal strength, the method for acquiring a sensor signal further includes:
if not, the alarm is controlled to alarm.
Specifically, if the lower limit value of the signal strength range is not less than the minimum signal strength, it indicates that it is not suitable to perform subsequent steps, and the step of checking and searching for errors needs to be re-checked and adjusted, so that the worker can find the problem in time and perform correction work, and the alarm can be controlled to give an alarm in the embodiment of the present invention.
The alarm may be of various types, for example, may be a buzzer or the like, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, the determining of the lowest value of the signal strength of the target sensor transmitting signal that can be sensed by the receiving device is specifically:
and detecting the lowest signal intensity value of the target sensor transmitting signal sensed by the receiving equipment by using the signal detection equipment.
In particular, in consideration of the high requirement on the accuracy of the minimum signal strength value, the signal detection device is used for directly detecting, so that the minimum signal strength value of the target sensor transmitting signal which can be sensed by the receiving device can be obtained accurately, the service life of the sensor can be prolonged, and the replacement frequency can be reduced.
Of course, besides this method, other methods may also be used to detect the lowest signal strength value of the target sensor transmission signal that can be sensed by the receiving device, and the embodiment of the present invention is not limited herein.
In a preferred embodiment, the target sensor transmits a radio frequency signal;
the signal intensity minimum value of the target sensor transmitting signal sensed by the receiving equipment detected by the signal detection equipment is specifically as follows:
detecting the frequency spectrum of a signal transmitted by a target sensor by using a frequency spectrograph in the process of controlling the reduction of the power supply voltage of the target sensor;
and taking the lowest frequency of the target sensor transmitting signal which can be detected by the frequency spectrograph as the lowest value of the signal intensity of the target sensor transmitting signal which can be sensed by the receiving equipment.
Specifically, signals transmitted by various types of sensors are all radio frequency signals, so in the embodiment of the present invention, a sensor is defined as a sensor whose transmission signal is a radio frequency signal, the signal strength of the radio frequency signal can be specifically represented by the frequency of the signal transmitted by the sensor, and in practical applications, the receiving device also sets the signal strength receiving range by using the signal frequency, so that the lowest value of the signal strength of the target sensor transmission signal that can be sensed by the receiving device and detected by using the signal detection device may specifically be: in the process of linearly reducing the power supply voltage of the target sensor, detecting the frequency spectrum of a signal transmitted by the target sensor by using a frequency spectrograph; and taking the lowest frequency of the target sensor transmitting signal which can be detected by the frequency spectrograph as the lowest value of the signal intensity of the target sensor transmitting signal which can be sensed by the receiving equipment.
In the embodiment of the invention, the circuit board of the sensor can be disassembled, the battery of the sensor can be removed, the voltage stabilizing source is connected to the circuit board to supply power to the sensor, so that the power supply voltage of the sensor can be linearly reduced through the voltage stabilizing source, the sensor needs to be continuously activated by a trigger (sensor activating equipment) in the process so as to transmit signals by the sensor, the frequency spectrum information of the signals transmitted by the sensor is detected by the frequency spectrograph, when the signal transmitted by the sensor cannot be detected by the frequency spectrograph, the signal transmitted by the sensor under the power supply voltage at the moment cannot be sensed by the frequency spectrograph, and the finally detected lowest frequency is used as the lowest value of the signal intensity of the target sensor transmitted signals which can be sensed by the receiving equipment.
The lower limit of the signal strength range originally allowed to be received by the receiving device can also be detected by the above detection scheme, specifically: in the process of linearly reducing the power supply voltage of the sensor through the voltage stabilizing source, the sensor is continuously activated by using a trigger (sensor activation equipment) so as to transmit signals by the sensor, the frequency spectrum information of the signals transmitted by the sensor is detected by the frequency spectrograph at the same time, and when the trigger cannot successfully activate the sensor, the frequency value detected by the frequency spectrograph at the moment can be the lower limit value of the signal intensity range originally allowed to be received by the receiving equipment.
Specifically, the sensor in the embodiment of the present invention may be of various types, for example, a tire pressure sensor, and the like, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, in the process of controlling the power supply voltage of the target sensor to decrease, the detecting, by using the spectrometer, the frequency spectrum of the signal transmitted by the target sensor specifically includes:
in the process of supplying power to the target sensor by using the voltage stabilizing source, the output voltage of the voltage stabilizing source is controlled to be continuously reduced, and the frequency spectrum of the signal transmitted by the target sensor is detected by using the frequency spectrograph.
Specifically, in order to prevent the interference of the fluctuation of the power supply voltage on the detection result, the voltage stabilizing source is used for supplying power to the target sensor, the purpose of controlling the continuous reduction of the power supply voltage of the target sensor is achieved by controlling the continuous reduction of the output voltage of the voltage stabilizing source, and the interference caused by the fluctuation of the power supply voltage can be eliminated.
Of course, besides this way, the power supply voltage of the target sensor may be controlled to decrease in another way, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, the obtaining of the lowest signal strength that the current receiving device allows to receive the signal emitted by the target sensor specifically includes:
in the process of controlling the reduction of the power supply voltage of the target sensor, detecting the frequency spectrum of a signal transmitted by the target sensor by using a frequency spectrograph while periodically activating the target sensor by using the sensor activating equipment;
and when the sensor activation equipment cannot successfully activate the target sensor for the first time, the frequency value of the target sensor transmission signal detected by the frequency spectrograph is taken as the lowest signal strength which is currently allowed by the receiving equipment to receive the target sensor transmission signal.
Specifically, the sensor activation device may be regarded as a part of the receiving device, the receiving device may first activate the sensor through the sensor activation device, the sensor may only transmit the signal to the outside, and for the sensor activation device, the target sensor may only be successfully activated if the signal frequency of the target sensor transmission signal is within the preset signal frequency range that allows reception, so in the embodiment of the present invention, when the sensor activation device cannot successfully activate the target sensor for the first time, the frequency value of the target sensor transmission signal detected by the spectrometer is taken as the lowest signal strength that the receiving device currently allows reception of the target sensor transmission signal, and an accurate lowest signal strength that the receiving device currently allows reception of the target sensor transmission signal can be obtained.
As a preferred embodiment, after detecting the spectrum of the signal emitted by the target sensor by using the spectrometer in the process of linearly reducing the power supply voltage of the target sensor, the method for acquiring the sensor signal further includes:
the lowest frequency of the target sensor transmission signal which can be detected by the spectrometer and the current supply voltage of the target sensor are recorded.

the lowest value of the signal strength is directly used as the minimum signal strength which is allowed by the receiving device to receive the signal transmitted by the target sensor.
Specifically, in order to maximally increase the service life of the sensor, in the embodiment of the present invention, the lowest value of the signal strength may be directly used as the lower limit value of the signal strength range.
Of course, in addition to this manner, the sum of the signal strength minimum and the preset percentage of the signal strength minimum may be used as the minimum signal strength that the receiving device allows to receive the signal transmitted by the target sensor, and the embodiment of the present invention is not limited herein.
