Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an electronic device.
Background
With the development of electronic devices, the electronic devices are increasingly large in size and heavy in weight; in the process of using the electronic equipment, the user easily falls, and when the impact stress of the electronic equipment received in the falling moment reaches a certain degree, various functional performance anomalies of the electronic equipment can be caused, so that the normal use of the user is influenced.
At present, the common functional abnormality of the electronic equipment is caused by the fact that the electronic equipment causes transient state form change of a wafer in the crystal oscillator when the electronic equipment falls down, so that output frequency is disordered, a system is abnormal, and the problem of dead halt occurs. In order to avoid the abnormality of the crystal oscillator when the electronic equipment falls, a protection design for stress is generally performed on a chip (IC), for example, stress simulation is performed through computer aided engineering (Computer Aided Engineering, CAE) to enable the crystal oscillator to be far away from a stress area; or some of which are limited by Industry Design (ID) structurally and cannot avoid stress areas, may be dispensed on ICs or added with polyethylene terephthalate (Polyethylene terephthalate, PET) cushioning.
Although the modes can avoid the main board stress zone in advance and reduce the probability of being affected by stress, CAE simulation cannot simulate and cover all falling angles and falling forms, a plurality of risk angles cannot be hidden and early warning cannot be carried out, the crystal oscillator is sensitive to stress and is inconvenient to simulate in a mode of applying stress, and stress influence can be generated on the crystal oscillator through dispensing and covering by PET materials. The dispensing mode cannot ensure that the IC bonding pad and the body are uniformly covered when dispensing due to irregular dispensing modes, so that the colloid is heated and expanded when the electronic equipment heats, irregular expansion stress is generated, and the IC is influenced; therefore, the problem that the electronic equipment is easy to crash when falling can not be well solved by the mode.
Disclosure of Invention
The invention provides electronic equipment, which aims to solve the problem that the electronic equipment is easy to crash when falling.
In order to solve the technical problems, the invention is realized as follows:
the embodiment of the invention provides electronic equipment, which comprises: a crystal oscillator, a strain detection module and an on-off module;
the strain detection module is connected with the crystal oscillator and the on-off module;
the strain detection module is used for detecting the strain parameter of the crystal oscillator and outputting a pulse signal to the on-off module when the strain parameter meets a preset condition;
the on-off module responds to the pulse signal and controls the electronic equipment to enter a dormant state; and the crystal oscillator is in a closed state in the dormant state.
In the embodiment of the invention, the strain parameter of the crystal oscillator is detected through the strain detection module connected between the crystal oscillator and the on-off module, and a pulse signal is output to the on-off module under the condition that the strain parameter meets the preset condition; therefore, the on-off module can respond to the pulse signal output by the strain detection module to control the electronic equipment to enter the dormant state. Therefore, when the strain parameter meets the preset condition, namely the crystal oscillator in the electronic equipment generates strain, the electronic equipment is controlled to enter a dormant state, so that faults such as system halt and the like caused by influence of oscillation form of the crystal oscillator are avoided.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. 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.
Referring to fig. 1, an embodiment of the present invention provides an electronic device, including: a crystal oscillator 1, a strain detection module 2 and a startup and shutdown module 3;
the strain detection module 2 is connected with the crystal oscillator 1 and the on-off module 3;
the strain detection module 2 is configured to detect a strain parameter of the crystal oscillator 1, and output a pulse signal to the on-off module 3 when the strain parameter meets a preset condition;
the on-off module 3 responds to the pulse signal and controls the electronic equipment to enter a dormant state; wherein, the crystal oscillator 1 is in a closed state in the dormant state.
Specifically, the strain detection module 2 is connected to the crystal oscillator 1, so as to detect a strain parameter of the crystal oscillator 1. The strain detection module 2 is further connected to the on-off module 3, so as to output a pulse signal to the on-off module 3.
Alternatively, the crystal oscillator 1 includes a start-up circuit and a wafer, and when the crystal oscillator 1 is powered up, the wafer oscillates and a fixed frequency can be generated and output to the start-up circuit to generate a clock signal.
Optionally, the on-off module 3 may implement a function when an on-off key in the electronic device is triggered, for example: under the condition that the on-off module 3 receives the pulse signal, the electronic equipment enters a dormant state or a screen-off state; such as: under the condition that the electronic equipment is in a bright screen state, if the on-off key is triggered once, the electronic equipment is switched to a screen-off state.
In the above-mentioned scheme, the strain detection module 2 connected between the crystal oscillator 1 and the on-off module 3 is used for detecting the strain parameter of the crystal oscillator 1, and outputting a pulse signal to the on-off module 3 when the strain parameter meets the preset condition; so that the on-off module 3 controls the electronic device to enter the sleep state in response to the pulse signal output by the strain detection module 2. In this way, when the strain parameter meets the preset condition, that is, the crystal oscillator 1 in the electronic device generates strain, the electronic device is controlled to enter the sleep state, so that the faults of abnormal clock frequency, system halt and the like caused by the influence of the oscillation form of the crystal oscillator 1 are avoided.
Optionally, as shown in fig. 2, the strain detection module 2 includes: a threshold value generation circuit 21, a strain input circuit 22, and a comparison circuit 23;
the threshold value generating circuit 21 is connected to the comparing circuit 23, and the threshold value generating circuit 21 is configured to generate a threshold value parameter and transmit the threshold value parameter to the comparing circuit 23;
the strain input circuit 22 is connected to the crystal oscillator 1 and the comparison circuit 23, and the strain input circuit 22 is used for detecting a strain parameter of the crystal oscillator 1 and transmitting the strain parameter to the comparison circuit 23;
the comparison circuit 23 is connected to the on-off module 3, and the comparison circuit 23 is configured to compare the threshold parameter with the strain parameter, and output the pulse signal to the on-off module 3 when the preset condition is satisfied.
Wherein the threshold value parameter generated by the threshold value generating circuit 21 is the same as the type of the strain parameter detected by the strain input circuit 22; for example: the threshold parameter generated by the threshold generating circuit 21 may be a voltage value, and the strain parameter should also be expressed as a voltage value; the threshold parameter generated by the threshold generation circuit 21 may be a current value, and the strain parameter should also be represented as a current value so that the comparison circuit 23 compares the strain parameter with the threshold parameter.
It should be noted that, when the strain parameter is represented by a voltage value or a current value, it should not be understood in a narrow sense that the strain input circuit 22 only directly represents a change in the voltage value or the current value when the crystal oscillator 1 is strained, but may also represent a change in another parameter (such as a resistance) other than the voltage value or the current value when the strain input circuit 22 detects that the crystal oscillator 1 is strained, and further the strain input circuit 22 may convert the change in the other parameter into a parameter of the same type as the threshold parameter, so that the comparison circuit 23 compares the strain parameter with the threshold parameter.
Optionally, the strain input circuit 22 includes: a strain sensor 221; the strain sensor 221 is disposed on the crystal oscillator 1 and connected to the comparison circuit 23;
the strain input circuit 22 detects a strain parameter of the crystal oscillator 1 through the strain sensor 221 and transmits the strain parameter to the comparison circuit 23.
Alternatively, the strain sensor 221 may be disposed on the surface of the crystal oscillator 1, so that the strain input circuit 23 can collect the strain parameter when the crystal oscillator 1 is strained by the strain sensor 221.
As shown in fig. 3, the crystal oscillator 1 may be disposed on the motherboard 4, and the strain sensor 221 may be disposed above the crystal oscillator 1. Other circuit parts in the strain detection module 2 may also be provided on the motherboard 4. Optionally, a shielding case 5 may be further disposed on the motherboard 4, and the crystal oscillator 1 and the strain detection module 2 may be located inside the shielding case 5.
As shown in fig. 4, at the moment when the electronic device is in contact with the dropping surface when dropped, the crystal oscillator 1 may be deformed due to the deformation of the main board 4, so that the deformation generated on the crystal oscillator 1 may be detected by the strain sensor 221 provided on the crystal oscillator 1.
Alternatively, the strain sensor 221 may be a resistive strain gauge, where the resistive strain gauge is disposed on the surface of the crystal oscillator 1. The resistive strain gauge may be constituted by a sensitive grating or the like for measuring the strain of the crystal oscillator 1. The resistance strain gauge is based on strain effect, namely, when a conductor or a semiconductor material is mechanically deformed under the action of external force, the resistance value of the resistance strain gauge correspondingly changes, so that the strain of the crystal oscillator 1 is detected. Therefore, when the main board is designed and laid out, the resistance strain gauge is laid out above the crystal oscillator 1, and when the mobile phone falls down, the main board is deformed due to stress impact, and the deformation is possibly conducted to the upper part of the crystal oscillator 1, the resistance strain gauge can be deformed to generate resistance change. The change in the resistance value can then be translated by the strain input circuit 22 into: the same type of strain parameter as the threshold parameter generated by the threshold generation circuit 21.
The strain detection module 2 is specifically described below with reference to specific examples:
as shown in fig. 5, the comparing circuit 23 includes a comparator 231; a first input In of the comparator 231 is connected to the threshold generation circuit 21; a second input terminal in+ of the comparator 231 is connected to the strain input circuit 22; the output end of the comparator 231 is connected to the on-off module 3.
The strain input circuit 22 includes: a resistance strain gauge and voltage divider circuit 222; the first end of the voltage dividing circuit 222 is connected to a constant voltage power supply, and the second end of the voltage dividing circuit 222 is connected to the first end of the resistance strain gauge and the comparison circuit 23 respectively; the second end of the resistance strain gauge is grounded; wherein the strain parameters are: the potential value of the first end of the resistance strain gauge.
The resistance strain gauge is equivalent to a variable resistor when detecting the strain of the crystal oscillator 1, such as the resistance R3 in fig. 5.
Alternatively, the voltage divider 222 may be a resistor divider, i.e. may be equivalently a fixed resistor, such as the resistor R2 in fig. 5. It should be noted that the resistor divider circuit may be formed by one resistor, or may be formed by a plurality of resistors connected in series, parallel, or series-parallel, and the embodiment of the present invention is not limited thereto.
Alternatively, the first connection terminal of the strain input circuit 22 may be connected to the power supply terminal VDD of the comparator 231, the second connection terminal of the strain input circuit 22 may be connected to the ground terminal of the comparator 231, and the output terminal of the strain input circuit 22 is connected to the second input terminal of the comparator 231. That is, the constant voltage power supply may be the power supply terminal VDD of the comparator 231; the second terminal of the resistance strain gauge may be directly connected to the ground GND of the comparator 231.
Optionally, the threshold generating circuit 21 includes: a constant voltage generation circuit 211, the constant voltage generation circuit 211 being connected to the comparison circuit 23, the constant voltage generation circuit 211 being configured to generate a constant voltage and transmit the constant voltage to the comparison circuit 23; wherein the threshold parameters are: the constant voltage value generated by the constant voltage generation circuit 211.
For example: the resistance generated by the resistive strain gauge is characterized by the change In the voltage value input to the second input terminal in+ by the strain input circuit 22, taking a constant voltage as the input value of the first input terminal In-of the comparator 231; thus, by comparing the voltage values of the first input terminal In-and the second input terminal in+, when the voltage value of the first input terminal In-is greater than the voltage value of the second input terminal in+, the comparator 231 outputs a low level signal to the switch module 3 (wherein the comparator 231 outputs a high level signal In a default state).
Of course, it should be noted that, by comparing whether the voltage values of the first input terminal In-and the second input terminal in+ meet the preset condition, the comparator 231 is related to the connection relationship between the threshold generating circuit 21 and the strain input circuit 22 and the first input terminal In-and the second input terminal in+ respectively, and the type of the comparator 231, which are merely illustrative, and the embodiment of the present invention is not limited thereto.
In this way, a constant voltage value is provided as a threshold parameter to the first input terminal In-of the comparator 231 by the constant voltage generating circuit 211, and the equivalent resistor R of the resistive strain gauge and the equivalent resistor R1 of the voltage dividing circuit are connected In series between the voltage terminal VDD and the ground terminal GND of the comparator 231 by the strain input circuit 22, so that when the resistance of the resistive strain gauge changes due to the strain of the crystal oscillator 1 due to the constant voltage of the voltage terminal VDD, the voltage value at both ends of the resistor R changes, and because one end of the resistor R is grounded, strain detection of the crystal oscillator 1 is realized by taking the potential value between the resistor R and the resistor R1 as the input value of the second input terminal in+ of the comparator 231, and the comparator 231 compares the voltage value of the first input terminal In-with the voltage value of the second input terminal in+ and outputs a low-level signal to the switch module 3 through the output terminal output according to the comparison result.
Specifically, the constant voltage generation circuit 211 may include a second resistor R2 and a third resistor R3; the first end of the second resistor R2 is connected to the power supply end (e.g., the normal power supply end VCC of the motherboard), the second end of the second resistor R2 is connected to the first end of the third resistor R3 and the first input end In of the comparator 231, and the second end of the third resistor R3 is grounded.
In this way, the second resistor R2 and the third resistor R3 are connected In series between the power supply terminal VCC and the ground terminal, and since the voltage of the power supply terminal VCC is constant, the divided voltage signal (divided voltage signal is constant voltage) of the third resistor R3 can be used as the threshold parameter input at the first input terminal In-of the comparator 231.
Optionally, the strain detection circuit 2 may further include a fourth resistor R4, where a first end of the fourth resistor R4 is connected to the voltage terminal VDD of the comparator 231, and the other end is connected to the output terminal output of the comparator 231.
In the above scheme, at the moment when the electronic device falls, the resistance strain gauge is strained to generate a change of resistance, and the resistance becomes low, so that the output voltage of the comparator 231 is switched to a low level (for example, corresponding to the falling edge of the output signal in fig. 5); after the falling action is completed, the resistance value of the resistance strain gauge is gradually recovered in the stress releasing process (for example, the low level state of the output signal in the corresponding fig. 5); after the stress is released, the resistance value of the resistance strain gauge is restored to the initial state, the comparator 231 is restored to the high level from the low level (for example, the rising edge of the output signal in fig. 5 is corresponding to the output end), that is, the output level of the comparator 231 completes the action of a negative pulse signal from the high level to the low level and then to the high level, and the negative pulse signal is equivalent to the trigger action of the on-off button in the analog electronic device, so that the electronic device enters the dormant state.
Optionally, according to at least one embodiment above, as shown in fig. 6, the electronic device further includes:
the delay latch module 6 is connected with the strain detection module 2 and the on-off module 3;
the delay latch module 6 is configured to store a pulse signal output by the strain detection module 2, and send the stored pulse signal to the on-off module 3 after the strain detection module 2 outputs the pulse signal to the on-off module 3 for a predetermined period of time;
when the electronic equipment is in a dormant state, the on-off module 3 responds to the pulse signal output by the delay latch module 6 to control the electronic equipment to enter an awake state; wherein, the crystal oscillator 1 is in an on state in the wake-up state.
For example: the pulse signal output by the strain detection module 2 is latched through the delay latching module 6, and after the stress release is finished, namely after the resistance value of the resistance strain gauge is restored to an initial state, the delay is delayed for a preset time (such as delay 1S), and a low-level pulse is triggered to the on-off module 3 again to wake up the dormant state of the electronic equipment, namely the electronic equipment enters the wake-up state, so that the electronic equipment enters the system working state of the electronic equipment, and the electronic equipment is ensured to work normally after falling.
Specifically, the on-off module 3 responds to the pulse signal output by the delay latch module 6 to control the electronic device to switch from the off-screen state to the on-screen state (or called wake-up sleep state), that is, if the on-off key is triggered once when the electronic device is in the off-screen state, the electronic device is switched to the on-screen state.
Wherein, the delay latch module 6 may specifically include:
a pulse latch 61 connected to the strain detection module 2; the pulse latch 61 is used for storing a pulse signal output by the strain detection module 2;
a delay circuit 62 connected to the pulse latch 61 and the on-off module 3; the delay circuit 62 is configured to send the stored pulse signal to the on-off module 3 after the strain detection module 2 outputs the pulse signal to the on-off module 3 for a predetermined period of time.
For example: the pulse signal output by the strain detection module 2 is latched through the pulse latch 61, so that after the stress release is finished, namely, after the resistance value of the resistance strain gauge is restored to an initial state, a low-level pulse is triggered to the on-off module 3 again after a predetermined time (such as time delay 1S) is delayed by the time delay circuit 62, so that the dormant state of the electronic equipment is awakened, namely, the electronic equipment enters an awakening state, and the system working state of the electronic equipment is entered, so that the electronic equipment can work normally after falling.
In the above scheme, when the electronic equipment falls, the strain detection circuit 2 detects the strain of the crystal oscillator 1, and triggers the low pulse signal to the on-off module 3, so that the electronic equipment enters a dormant state to close the crystal oscillator 1, and the influence of the falling stress on the electrical performance of the crystal oscillator 1 is avoided; when the dropping is completed, i.e. the stress release is completed, the electronic device can also wake up in a sleep state, i.e. the electronic device enters a wake-up state, so that the crystal oscillator 1 is restarted. According to the scheme, the risk of dead halt of the electronic equipment in a falling scene can be reduced, and the stability and reliability of the electronic equipment are enhanced.
As shown in fig. 7, the embodiment of the present invention further provides a control method of an electronic device, including:
step 71: and obtaining the strain parameter of the crystal oscillator in the electronic equipment.
Alternatively, the strain sensor disposed on the crystal oscillator may be used to detect the strain parameter on the crystal oscillator, which may be specifically described in the above-mentioned embodiments of the electronic device, and will not be described herein.
Step 72: controlling the electronic equipment to enter a dormant state through a startup and shutdown module under the condition that the strain parameter meets a preset condition; and the crystal oscillator is in a closed state in the dormant state.
Optionally, when the strain parameter meets the preset condition, the low-level pulse signal may be output by the power on/off module to enable the electronic device to enter the sleep state when the strain parameter is smaller than the threshold parameter, which may be specifically referred to the embodiment of the electronic device, and in order to avoid repetition, details are not repeated here.
In this embodiment, the electronic device is controlled to enter the sleep state by the on-off module by acquiring a strain parameter on a crystal oscillator in the electronic device, where the strain parameter meets a preset condition. Therefore, when the strain parameter meets the preset condition, namely the crystal oscillator in the electronic equipment generates strain, the electronic equipment is controlled to enter a dormant state through the on-off module, so that faults such as system halt and the like caused by abnormal clock frequency due to the influence of the oscillation form of the crystal oscillator are avoided.
Optionally, after the step 72, the method may further include: after the electronic equipment is in a dormant state and a preset time period passes, controlling the electronic equipment to enter an awake state through the on-off module; wherein, the crystal oscillator is in an on state in the wake-up state.
Optionally, when the electronic device enters the sleep state and a predetermined period of time passes, a low-level pulse signal is sent to the power on/off module again, so that the electronic device enters the wake-up state, which can be described specifically with reference to the embodiment of the electronic device, and in order to avoid repetition, a description is omitted here.
In this embodiment, after the stress release is completed after the electronic device falls, a low-level pulse is triggered to the on-off module 3 again after a predetermined time (for example, time delay 1S) to wake up the sleep state of the electronic device, that is, the electronic device enters the wake-up state, so as to enter the system working state of the electronic device, and ensure that the electronic device can work normally after falling.
As shown in fig. 8, an embodiment of the present invention further provides an electronic device 800, including:
an obtaining module 810, configured to obtain a strain parameter of a crystal oscillator in the electronic device;
the sleep module 820 is configured to control the electronic device to enter a sleep state through the on/off module when the strain parameter meets a preset condition;
and the crystal oscillator is in a closed state in the dormant state.
Optionally, the electronic device 800 further includes:
the wake-up module is used for controlling the electronic equipment to enter a wake-up state through the on-off module after the electronic equipment enters a sleep state and a preset time period passes;
wherein, the crystal oscillator is in an on state in the wake-up state.
The electronic device provided in the embodiment of the present invention can implement each process implemented by the electronic device in the method embodiment of fig. 7, and in order to avoid repetition, a description is omitted here.
In the above embodiment, the electronic device 800 obtains the strain parameter of the crystal oscillator in the electronic device, and controls the electronic device to enter the sleep state through the power on/off module when the strain parameter meets the preset condition.
