Description
Technical Field
The invention relates to the technical field of sensors, in particular to a pressure-sensitive control protection system, a pressure-sensitive control protection method and a computer readable storage medium.
Background
At present, with the development of fine engineering technology, pressure sensors are adopted in more and more devices and a plurality of mechanical property testing systems, and the pressure sensors have the characteristics of simple structure and low cost, and the testing system is mature in technology, so that the pressure sensors can be widely applied. Pressure sensors, which are devices that are widely used and therefore receive attention from a wide range of users, are elements that output applied pressure as an electrical signal. Pressure sensors are widely used in, for example, artificial skin, human operation thereof, and the like.
The pressure sensors are divided into piezoresistive pressure sensors, ceramic pressure sensors, diffused silicon pressure sensors, sapphire pressure sensors and piezoelectric pressure sensors; the working principle of the piezoresistive pressure sensor is that a resistance strain gauge is one of the main components of the piezoresistive strain sensor. The working principle of the metal resistance strain gage is that the resistance value of the strain resistor adsorbed on the substrate material changes along with the mechanical deformation, which is commonly called as resistance strain effect. The working principle of the ceramic pressure sensor is that the ceramic pressure sensor is based on the piezoresistive effect, pressure is directly acted on the front surface of a ceramic diaphragm to enable the diaphragm to generate tiny deformation, a thick film resistor is printed on the back surface of the ceramic diaphragm to be connected into a Wheatstone bridge, the bridge generates a voltage signal which is in direct proportion to the pressure and is highly linear and is also in direct proportion to excitation voltage due to the piezoresistive effect of a piezoresistor, the standard signal is calibrated to be 2.0/3.0/3.3mV/V and the like according to different pressure ranges and can be compatible with a strain sensor, the working principle of the diffused silicon pressure sensor is also based on the piezoresistive effect, the pressure of a measured medium is directly acted on the diaphragm (stainless steel or ceramic) of the sensor by utilizing the piezoresistive effect, the diaphragm generates micro displacement which is in direct proportion to the pressure of the medium, the resistance value of the sensor is changed, the change is detected by utilizing an electronic circuit and is converted to output a standard measuring signal corresponding to the pressure, and the working principle of the sapphire pressure sensor utilizes the strain type working principle of utilizing silicon-resistor as a semiconductor element which has no ethical characteristics and has no ethical characteristics. Therefore, the semiconductor sensitive element manufactured by using the silicon-sapphire is insensitive to temperature change and has good working characteristics even under high-temperature conditions; the sapphire has strong radiation resistance; in addition, the silicon-sapphire semiconductor sensitive element has no p-n drift, the working principle of the piezoelectric pressure sensor is that the piezoelectric effect is the main working principle of the piezoelectric sensor, the piezoelectric sensor cannot be used for static measurement, and because the charge after the external force action is stored only when a loop has infinite input impedance. This is not the case in practice, so it is decided that the piezoelectric sensor can only measure dynamic stresses.
When the pressure sensor is applied to the mobile phone, when the pressure sensor is arranged in the mobile phone, when a finger presses the screen, the pressure sensor in the mobile phone screen detects the pressure value on the mobile phone screen, compares the pressure value detected on the mobile phone screen with a preset value, and can only be controlled when the detected pressure value reaches the preset value, and cannot be operated when the detected pressure value fails to reach the preset value, so that a problem can occur.
In summary, the technical problem actually solved by the present invention is how to solve the problem of performing effective control in the case where the applied pressure is unstable.
Disclosure of Invention
In view of the above, an object of the present invention is to provide a protection system for pressure-sensitive control.
In order to achieve the purpose, the invention adopts the following technical scheme:
a pressure-sensitive controlled protection system comprising: a pressure sensitive sensor, a calculation module; the calculation module is internally provided with a first pressure threshold and a second pressure threshold;
the pressure-sensitive sensor is arranged in the mobile phone and used for detecting a pressure value when pressure is applied to a screen of the mobile phone and sending the detected pressure value to the computing module, the computing module receives the pressure value detected by the pressure-sensitive sensor and compares the received pressure value with a first pressure threshold value through the computing module, and when the detected pressure value is larger than or equal to the first pressure threshold value, the computing module forms a control instruction and controls operation through the control instruction;
after the calculation module forms a control instruction, the pressure-sensitive sensor can also continuously detect the pressure value of the pressure and continuously send the detected pressure value to the calculation module, the calculation module compares the continuously received pressure value with a second pressure threshold value, when the continuously detected pressure value is not smaller than the second pressure threshold value, the control instruction cannot stop and is continuously controlled, and when the continuously detected pressure value is smaller than the second pressure threshold value, a stop instruction is formed to invalidate the control instruction and stop the control operation.
Further, a third pressure threshold value is further arranged in the calculation module, the third pressure threshold value is larger than the first pressure threshold value, after the calculation module forms a control instruction, the calculation module compares a pressure value continuously detected by the pressure-sensitive sensor with the third pressure value at the same time, when the detected pressure value is larger than or equal to the third pressure threshold value, a protection instruction is formed in the calculation module, the excessive pressure applied at the moment is reminded, a user is reminded to reduce the pressure, so that the loss of a mobile phone screen is avoided, or damage is caused to other components arranged in the mobile phone due to the excessive pressure, the user is reminded by displaying on the mobile phone screen, but in the reminding process, the control instruction cannot stop, and the control will still take effect.
Further, when a control instruction is not formed in the calculation module and the pressure value of the applied pressure is too large at the moment and directly exceeds the third pressure threshold value, the calculation module also directly forms the control instruction, forms a protection instruction while forming the control instruction, displays the formed protection instruction on the screen of the mobile phone, and prompts a user that the applied force is too large.
Further, after the calculation module forms the control instruction, the pressure-sensitive sensor further continuously detects a pressure value of the pressure on the mobile phone screen, and sends the continuously detected pressure value to the calculation module, after the calculation module continuously receives the pressure value detected by the pressure-sensitive sensor, the pressure-sensitive sensor is compared with a second pressure threshold, when the detected pressure value is smaller than the second pressure threshold, a stop instruction should be formed according to the above situation, and when the pressure-sensitive sensor can still detect the pressure value of the pressure on the mobile phone screen, although the pressure value is smaller than the second pressure threshold at this time, the pressure actually exists, a warning instruction is generated to warn a user whether the user is operating, if the user is operating, the operation is unstable due to insufficient pressure applied at this time, and therefore, the user is required to increase the applied pressure, so as to ensure that stable control can be performed.
Furthermore, after the user sees the reminding information, the pressure on the screen is increased, and because the hand does not leave the mobile phone screen at the moment, the user directly increases the strength of the hand acting on the mobile phone screen, the same operation is judged, and therefore, when the increased pressure is greater than or equal to the second pressure threshold, a control instruction is directly formed without reaching the first pressure threshold.
Further, according to the protection system, when a plurality of applied pressures simultaneously occur on the sensing area of the pressure-sensitive sensor, a plurality of pressure values are detected simultaneously, and at the moment, the calculation module compares the pressure value of each pressure with the first pressure threshold, the second pressure threshold and the third pressure threshold respectively, so that the pressure values of the plurality of pressures are detected, and a control instruction, a stop instruction and a reminding instruction are formed respectively.
In view of the above, another objective of the present invention is to provide a protection method applied to the protection system, which includes the following steps:
the pressure-sensitive sensor senses the pressure value of the pressure on the screen of the mobile phone and transmits the sensed pressure value to the computing module;
the calculation module receives a pressure value detected by the pressure-sensitive sensor, compares the received pressure value with a second pressure threshold value, and forms a control instruction to control operation when the received pressure value is greater than or equal to the first pressure threshold value;
after the calculation module forms a control instruction, the calculation module continuously receives a pressure value of pressure on a mobile phone screen continuously detected by the pressure-sensitive sensor, compares the continuously received pressure value with a second pressure threshold value, when the received pressure value is not smaller than the second pressure threshold value, the control instruction is still effective to effectively control operation, and when the continuously received pressure value is smaller than the second pressure threshold value, the calculation module forms a stop instruction to stop control of the control instruction and does not operate.
The invention also discloses a computer readable storage medium having a computer program stored thereon, which when executed by a processor performs the steps as described above.
The invention has the advantages that the problem that the effective control is carried out under the condition that the applied pressure is unstable is solved, and the user can be reminded when the pressure is overlarge, so that the mobile phone is protected, all components in the mobile phone are protected from being damaged when the pressure is overlarge, and the user can be reminded when the pressure is small; meanwhile, when a plurality of pressures are simultaneously applied to the same area of the pressure-sensitive sensor, the plurality of pressures can be analyzed and protected respectively.

Referring to fig. 1, the embodiment provides a protection system for pressure-sensitive control, which includes a pressure-sensitive sensor and a computing module; the mobile phone comprises a calculation module, a pressure-sensitive sensor, a first pressure threshold value 1, a second pressure threshold value 2, a first pressure threshold value 1 and a second pressure threshold value 2, wherein the first pressure threshold value 1 is larger than the second pressure threshold value 2, the pressure-sensitive sensor is arranged in the mobile phone and used for detecting a pressure value 3 of pressure on a screen of the mobile phone and sending the pressure value 3 of the detected sensed pressure to the calculation module, the calculation module compares the pressure value 3 with the first pressure threshold value 1 when receiving the pressure value 3 of the pressure detected by the pressure-sensitive sensor, and when the received pressure value 3 is larger than or equal to the first pressure threshold value 3, the calculation module forms a control instruction and controls the operation of the mobile phone through the formed control instruction; when the calculation module forms a control instruction, the pressure-sensitive sensor further continuously detects a pressure value 3 of the pressure on the mobile phone screen and sends the continuously detected pressure value 3 to the calculation module, the calculation module compares the received pressure value 3 with a second pressure threshold value 2, and when the received pressure value is not less than the second pressure threshold value 3 after the control instruction is formed, the control instruction is still effective, and the pressure of the mobile phone screen can be effectively utilized to control the mobile phone to operate; when the pressure value 3 is smaller than the second pressure threshold value 3, the calculation module forms a stop instruction to stop the operation of the control instruction.
The above embodiment illustrates that, when the first pressure threshold 1 is 100 and the second pressure threshold 2 is 80, when the pressure sensor provided in the mobile phone detects the pressure value 3 of the pressure, the pressure value 3 detected at this time is sent to the calculation module, so as to be compared with the first pressure threshold 1 and the second pressure threshold 2, and when the detected pressure value 3 is greater than the first pressure threshold 1, that is, the detected pressure value 3 is greater than or equal to 100, at this time, the calculation module will form a control command to perform the control operation.
As shown in fig. 2, after the control instruction is formed, the pressure sensor continuously detects a pressure value 3 on the mobile phone screen, and sends the detected pressure value 3 to the calculation module, the calculation module receives the pressure value 3 detected by the pressure sensor, and since the control instruction is formed at this time, the pressure value received at this time is compared with the second pressure threshold 2, when the pressure value 3 at this time is not less than the second pressure threshold 2, that is, the pressure value 3 at this time is not less than 80, the calculation module continuously controls, that is, as long as the initial pressure value 3 is greater than 100, as long as the hand of the user does not leave the mobile phone screen, the hand is continuously on the mobile phone screen, and as long as the pressure value 3 at this time is not less than the second pressure threshold 2, that is, not less than 80, the control module continuously controls.
After the calculation module forms the control command, since the control command is formed at this time, the received pressure value 3 is compared with the second pressure threshold value 2, and when the pressure value 3 at this time is smaller than the second pressure threshold value 2, that is, when the pressure value 3 at this time is smaller than 80, the calculation module forms a stop command, which is that the control command stops running.
The computing module is also internally provided with a third pressure threshold 4, the third pressure threshold 4 is larger than the first pressure threshold 1, after the computing module forms a control instruction, the computing module sends a pressure value 3 of the pressure received by the pressure-sensitive sensor to the computing module, the computing module compares the pressure value 3 received at the moment with the third pressure threshold 4, when the comparison result shows that the pressure value 3 received at the moment is larger than or equal to the third pressure threshold 4, the computing module forms a protection instruction at the moment, the content of the protection instruction is used for reminding a user, at the moment, due to the fact that the applied pressure is too large, a mobile phone screen can be influenced, other components in the mobile phone can also be influenced, the service life of the mobile phone or components in the mobile phone is shortened, the protection instruction runs on the mobile phone screen, and is displayed on the mobile phone screen to remind the user.
The embodiment describes that, when the value of the third pressure threshold 4 is 120, after the calculation module forms a control instruction, the pressure-sensitive sensor continuously detects a pressure value of the pressure on the mobile phone screen, and sends the detected pressure value to the calculation module, the calculation module compares the received pressure value 3 at the moment with the third pressure threshold 4, that is, compares the pressure value 3 at the moment with the pressure value 120, and normally controls the pressure value 3 at the moment through the control instruction when the pressure value reaches 120, and when the pressure value is greater than 120, a protection instruction is formed through the calculation module, a user is prompted by displaying the protection instruction on the screen, the content of the prompt is a user prompt, at this time, due to the fact that the applied pressure is too large, the mobile phone screen will be affected, other components in the mobile phone will also be affected, the service life of the mobile phone or components in the mobile phone will be reduced, and the protection instruction runs on the mobile phone screen, and displays the user prompt with the mobile phone screen.
When the control instruction is not formed in the calculation module, namely when the user puts fingers on the screen or puts the hand of the user on the screen, but the pressure value 3 of the pressure detected by the pressure-sensitive sensor is not greater than or equal to the first pressure threshold value 1 because the applied pressure is too small, the control instruction cannot be formed, and when the user suddenly raises the pressure originally put on the mobile phone screen, the pressure value 3 of the pressure directly exceeds the third pressure threshold value 4, or when the pressure value 3 of the pressure firstly contacting the mobile phone screen is directly greater than or equal to the third pressure threshold value 4 when the user uses the mobile phone, the calculation module directly forms the control instruction and simultaneously generates the protection instruction.
This embodiment describes that, when the hand of the user touches the screen, but the force applied at this time is less than the first pressure threshold 1, that is, the pressure value applied at this time is less than 100, so that the control instruction cannot be formed, and when the user suddenly increases the pressure at this time, the pressure is suddenly increased to exceed 120, and at this time, the calculation module directly generates the control instruction and also generates the protection instruction; when the hand of the user does not touch the mobile phone screen, the pressure-sensitive sensor cannot detect the pressure value 3 of the mobile phone screen due to the fact that the hand of the user cannot touch the mobile phone screen, the control instruction cannot be generated, and when the user puts the hand on the mobile phone screen suddenly and puts the hand on the mobile phone screen greatly, the pressure value at the moment directly exceeds the third pressure threshold value 4, namely directly exceeds 120, the calculation module generates the control instruction at the moment and simultaneously generates the protection instruction.
After calculation module forms the instruction, and then when the pressure value 3 that detects is less than second pressure threshold 2, calculation module forms and stops the instruction after, and when pressure sensor still can sense the pressure on the cell-phone screen, pressure sensor will be less than in pressure value 3 transmission to calculation module of second pressure threshold 2, calculation module forms and reminds the instruction, will remind the instruction to show through cell-phone module and remind the user on the cell-phone screen, remind the content can be for: if the pressure is insufficient, stable control cannot be performed, and if the operation needs to be continued, the control force needs to be increased.
The embodiment describes that, after the calculation module forms the control instruction, that is, after the detected pressure value 3 is greater than or equal to 100, the calculation module forms the control instruction, and then the detected pressure value 3 is smaller than the second pressure threshold 2, that is, after the pressure value 3 is smaller than 80, the calculation module forms the stop instruction, and then when the hand of the user is still on the mobile phone screen, the pressure-sensitive sensor can still sense the pressure, but because the pressure is insufficient, effective control cannot be performed, at this time, the pressure-sensitive sensor transmits the detected pressure value 3 smaller than the second pressure threshold 2 to the calculation module, the calculation module receives the pressure value 3 smaller than the second pressure threshold 2 and then forms the reminding instruction, and reminds the user on the mobile phone screen.
And after the user sees the warning on the cell-phone screen, the user begins to increase the pressure of exerting, when pressure increases gradually, when being more than or equal to second pressure threshold 2, the calculating module will generate control command, namely after the control command has been generated originally, but because the user is just the pressure of exerting not enough, but the hand is still on the cell-phone screen, lead to uncontrollable, after reminding, after the user increases pressure, when pressure value 3 is more than or equal to second pressure threshold 2 will directly generate control command, namely more than or equal to 80 will generate control command, will not wait until exceeding first pressure threshold 1 and will generate control command, namely will not wait until exceeding 100 and will generate control command.
When the pressure-sensitive sensor detects a plurality of pressures in the sensing area, the pressure-sensitive sensor respectively sends the pressure values 3 of the plurality of pressures sensed simultaneously to the calculation module, and the calculation module compares the pressure value 3 of each pressure with the first pressure threshold value 1, the second pressure threshold value 2 and the third pressure threshold value 4 to respectively form a control instruction, a stop instruction and a reminding instruction for each pressure.
In this embodiment, when pressure is applied by multiple fingers simultaneously in a sensing area of the same pressure sensitive sensor, the pressure sensitive sensor respectively detects a pressure value 3 for each pressure, and respectively sends the detected pressure value 3 to the calculation module, the calculation module respectively compares the received pressure value 3 for each pressure with the first pressure threshold 1, the second pressure threshold 2, and the third pressure threshold 4, and respectively forms a control instruction, a stop instruction, and a prompt instruction for each pressure, that is, the same pressure sensitive sensor can simultaneously detect multiple pressures, and the same calculation module can simultaneously compare multiple pressure values, and can respectively control the pressure values after comparison.
It should be noted that the values (80, 100/120) given in the above embodiments are not unique values, but are only for easy understanding of the proposed values, and the content of the reminder is not unique but only for easy understanding.
