detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention provides an adaptation detecting device for a terminal and a keypad. As shown in FIG. 1, the adaptation detecting device for the terminal and the keypad is connected between the terminal control chip and the keypad. The device for detecting and adapting the terminal and the keypad includes a main control chip. Referring to FIG. 2, FIG. 2 is a schematic diagram of the functional module of the first embodiment of the device for detecting the terminal and the keypad.

In this embodiment, the main control chip of the adaptation detecting device for the terminal and the keypad includes:

The output module 10 is configured to output a preset voltage detection signal to the terminal, and the terminal queries and feeds back a key value corresponding to the voltage value of the voltage detection signal;

In the present invention, the terminal button detecting system is constituted by the terminal, the fitting detecting device for the terminal and the key sheet, and the key sheet. As shown in FIG. 1, the adaptation detecting device for the terminal and the keypad is connected between the terminal control chip and the keypad. The terminal includes, but is not limited to, a device with a button such as a television or a mobile phone. When each terminal is in production, the manufacturer sets a corresponding voltage interval for the key value of each function button of the terminal. Since different manufacturers have different setting standards for the voltage ranges corresponding to the key values, that is, the voltage intervals corresponding to each key value are currently not uniformly specified. For example, the voltage range corresponding to the key value of the "increase volume" function button in one terminal is 0-0.5v, and the voltage range corresponding to the key value of the "increase volume" function button in another terminal is 0.2-0.8. v. Therefore, it is necessary to determine the voltage interval corresponding to each key value of the terminal.

In this embodiment, the main control chip for the adaptation detecting device of the terminal and the keypad includes, but is not limited to, a 51 single chip microcomputer. The output module 10 of the main control chip outputs preset voltage detection signals to the terminal. The terminal stores a preset relationship between the key value and the voltage value. When the terminal receives the voltage detection signal output by the output module 10, the terminal queries the preset key value and voltage value relationship table to query whether there is a key value corresponding to the voltage value of the voltage detection signal. For example, if the preset key value and voltage value relationship table is a correspondence table between the key value and the voltage interval, the terminal queries the received voltage detection signal in the correspondence table between the key value and the voltage interval. Whether the voltage value is within a voltage range corresponding to a certain key value. When it is queried that the voltage value of the voltage detection signal is within a voltage interval corresponding to a certain key value, that is, the key value corresponding to the voltage value of the voltage detection signal is queried; otherwise, the voltage is not queried. The key value corresponding to the voltage value of the detection signal. When the terminal queries the key value corresponding to the voltage value of the voltage detection signal, the terminal feeds back the queried key value, that is, the key value corresponding to the voltage value of the voltage detection signal. When the terminal does not query the key value corresponding to the voltage value of the voltage detection signal, that is, when the voltage value of the voltage detection signal does not have a corresponding key value, the terminal feeds back the invalid value.

After the output module 10 outputs a voltage detection signal to the terminal, the determining module 20 of the main control chip receives the key value fed back by the terminal or receives an invalid value fed back by the terminal. The output module 10 outputs a plurality of voltage detection signals, and the terminal may feed back the same key value, that is, the determining module 20 may receive the terminal to feedback the same key value multiple times. When the output module 10 outputs the voltage detection signal, the determining module 20 determines the voltage interval corresponding to each key value according to each received key value and the voltage value of the voltage detection signal corresponding to each received key value. And save. For example, if the voltage value of the five voltage detection signals corresponds to the key value of the “increase volume” function button, the determination module 20 determines the key value corresponding to the “increase volume” function button according to the voltage values of the five voltage detection signals. The voltage interval is saved; if the voltage value of the eight voltage detection signals corresponds to the key value of the “reduced volume” function button, the determining module 20 determines the key of the “reduced volume” function button according to the voltage values of the eight voltage detection signals. The voltage range corresponding to the value is saved.

The obtaining module 30 is configured to acquire a voltage value corresponding to the button signal when detecting a button signal triggered by the keypad;

After the determining module 20 determines the voltage interval corresponding to each key value of the terminal, the voltage value corresponding to each button of the keypad is acquired. The following takes the button on the button as an example to describe the voltage value corresponding to the button. When the user presses the button on the button, the button signal corresponding to the button is generated, and the button signal is transmitted to the main control chip. When the acquiring module 30 of the main control chip detects the button signal, the button signal is acquired. Voltage value.

The processing module 40 is configured to determine a positional relationship between a voltage value corresponding to the button signal and any one of the voltage intervals, and determine, according to the positional relationship, whether the terminal is adapted to the keypad.

After the obtaining module 30 obtains the voltage value corresponding to the button signal, the processing module 40 compares the voltage value corresponding to the button signal with the voltage interval corresponding to each key value of the saved terminal, and determines the voltage value corresponding to the button signal. The positional relationship of the voltage interval corresponding to each key value of the saved terminal, and determining whether the terminal is adapted to the keypad according to the determined positional relationship. Specifically, as shown in FIG. 3, the processing module 40 includes:

The comparison unit 41 is configured to compare a voltage value corresponding to the button signal with any of the voltage intervals to determine a positional relationship between a voltage value corresponding to the button signal and the voltage interval;

The determining unit 42 is configured to: when the voltage value corresponding to the button signal does not belong to any voltage interval, or the voltage value corresponding to the button signal belongs to one of the voltage ranges but the difference from the threshold voltage value of the voltage interval is less than When the voltage difference threshold is set, it is determined that the terminal is not adapted to the keypad.

In this embodiment, the comparison unit 41 compares the acquired voltage value with the voltage interval corresponding to each key value of the saved terminal, and determines whether the obtained voltage value belongs to a certain key value of the terminal. Voltage range. If the obtained voltage value does not belong to a voltage interval corresponding to any button of the terminal, that is, for the terminal, the button corresponding to the button signal is invalid, and the determining unit 42 determines the terminal and the The keypad is not suitable.

If the comparison unit 41 determines that the acquired voltage value belongs to a voltage interval corresponding to a certain key value of the terminal, further calculating each threshold voltage value of the obtained voltage value and the voltage interval corresponding to the key value. Absolute difference. Generally, the voltage interval corresponding to the key has two threshold voltage values, and the processing module 40 respectively calculates the absolute difference between the obtained threshold voltage values of the voltage range corresponding to the key value. In this embodiment, a preset voltage difference threshold is set in advance, and the preset voltage difference threshold is flexibly set according to actual conditions, and is not limited herein. In the calculated absolute difference value of the threshold voltage value of the voltage range corresponding to the key value, the comparison unit 41 determines whether there is an absolute difference value smaller than the preset voltage difference threshold value. If there is a certain absolute difference that is less than the preset voltage difference threshold, that is, the voltage value corresponding to the button signal is close to the threshold voltage value of the voltage interval corresponding to the key value. In this case, the The key value is the key value of the button corresponding to the button signal. Therefore, the determining unit 42 determines that the terminal is not adapted to the keypad. If there is no absolute difference value that is less than the preset voltage difference threshold, that is, the absolute difference between any obtained threshold voltage value of the voltage value corresponding to the key value is greater than or equal to When the voltage difference threshold is preset, the determining unit 42 determines that the key value is the key value of the button corresponding to the button signal.

In the solution proposed in this embodiment, after the terminal module is assembled with the button board, after the output module 10 outputs each preset voltage detection signal to the terminal, the determining module 20 determines, according to the key values fed back by the terminal and the voltage values of the respective voltage detection signals. The voltage interval corresponding to each key value of the terminal is determined and saved. After the user presses the button on the button, the acquiring module 30 acquires the voltage value corresponding to the button signal when the button signal triggered by the button is detected, and the processing module 40 according to the button The positional relationship between the voltage value corresponding to the signal and the voltage interval determines whether the terminal and the keypad are adapted. Therefore, it is timely detected whether the terminal and the keypad are adapted before the button panel of the terminal is assembled, so that when the detection is not adapted The rectification is performed to effectively prevent the terminal assembly from assembling the unsuitable keypad.

Further, a second embodiment of the method for detecting the adaptation of the terminal and the keypad is proposed based on the first embodiment. In this embodiment, the apparatus for detecting the terminal and the keypad further includes The main control chip is connected to the DAC module and the ADC module, wherein:

At this time, the determining module determines and stores the voltage interval corresponding to each key value according to the received key values and the actual voltage value of the corresponding voltage detection signal.

In this embodiment, the adaptation detecting device for the terminal and the keypad further includes a DAC (Digital to) respectively connected to the main control chip. Analog converter, digital to analog converter) module and ADC (Analog to Digital Converter, Analog to Digital Converter) module. The DAC module is further connected to the terminal control chip. When the output module 10 outputs the voltage detection signal of the digital signal format, the DAC module converts the voltage detection signal of the digital signal format into an analog signal and transmits the signal to the terminal. After receiving the voltage detection signal of the analog signal format, the terminal identifies the key value corresponding to the voltage detection signal, or identifies the voltage detection signal corresponding to the invalid value. The specific identification process is as described in the first embodiment, and details are not described herein again.

Since the actual voltage value of the preset voltage detection signal output by the output module 10 may have a certain error with the expected output voltage value, in the embodiment, when the DAC module converts the voltage detection signal of the digital signal format into After the analog signal, the ADC module samples the voltage detection signal of the analog signal format output by the DAC module, and performs analog-to-digital conversion on the sampled voltage detection signal to obtain an actual voltage value of the voltage detection signal. The determining module 20 determines and stores the voltage intervals corresponding to the respective key values according to the received key values and the actual voltage values of the corresponding voltage detection signals.

Moreover, in this embodiment, the ADC module is connected to the keypad, and when the user presses a button trigger button signal on the button, the button signal is an analog signal, and the ADC module performs the button signal. Sampling, and performing analog-to-digital conversion on the sampled button signal to obtain a voltage value of the button signal.

Further, in this embodiment, the voltage detection signal is a level signal whose voltage value starts from 0V and sequentially increases according to a preset unit, and the processing module 40 is further configured to:

In this embodiment, each preset voltage detection signal output by the output module 10 is a level signal whose voltage value starts from 0V and sequentially increases according to a preset unit, for example, a level signal sequentially increased according to an increasing law of 0.01V. . After the output module 10 outputs the voltage detection signal each time, the processing module 40 determines whether the voltage value of the voltage detection signal is greater than or equal to a preset voltage threshold. For example, if the preset voltage threshold is preset to be equal to the power supply voltage, the processing module 40 determines whether the voltage value of the voltage detection signal is greater than or equal to the power supply voltage. When the voltage value of the voltage detection signal output by the output module 10 is less than the preset voltage threshold, the output module 10 continues to output the voltage detection signal; when the voltage value of the voltage detection signal output by the output module 10 is greater than or equal to the preset voltage At the threshold, the processing module 40 controls the output module 10 to stop outputting the voltage detection signal, that is, the output module 10 outputs the voltage detection signal.

Further, as shown in FIG. 4, in the embodiment, the determining module 20 includes:

The processing unit 21 is configured to associate a voltage value of the voltage detection signal with the received key value when receiving a key value corresponding to the voltage detection signal fed back by the terminal;

The statistic unit 22 is configured to count, when the voltage detection signal output is completed, a maximum voltage value and a minimum voltage value among the plurality of voltage values associated with the respective key values;

The determining unit 23 is configured to determine a voltage interval corresponding to each key value according to the maximum voltage value and the minimum voltage value corresponding to the respective key values.

In this embodiment, each time the key value corresponding to the terminal feedback voltage detection signal is received, the processing unit 21 associates the key value with the voltage value of the voltage detection signal. When the output module 10 outputs the voltage detection signal, the statistics unit 22 counts a plurality of voltage values associated with the respective key values, and obtains a maximum voltage value and a minimum voltage value associated with the respective key values from the plurality of voltage values associated with the respective key values. Then, the determining unit 23 determines the voltage interval corresponding to each of the key values based on the maximum voltage value and the minimum voltage value associated with the respective key values. For example, if the maximum voltage value associated with a certain key value of the terminal is 0.56v and the associated minimum voltage value is 0.12v, the determining unit 23 determines that the voltage interval corresponding to the key value is [0.12, 0.56] v. .

The display screen may be an LCD liquid crystal display, which is not limited herein. The voltage display corresponding to each key value of the terminal, the voltage value corresponding to the key signal, and the prompt information that is not adapted when the terminal and the keypad are not adapted may be displayed through the display screen.

In the solution proposed in this embodiment, each voltage detection signal output by the output module 10 is a level signal whose voltage value starts from 0V and sequentially increases according to a preset unit until the voltage value of the voltage detection signal is greater than or equal to a preset voltage threshold. The processing module 40 controls the output module 10 to stop outputting the voltage detection signal. By gradually increasing the voltage value of the voltage detection signal, the voltage value corresponding to each key value of the terminal can be accurately determined, thereby accurately obtaining the voltage interval corresponding to each key value, thereby realizing more accurate detection of whether the terminal and the keypad are adapted, thereby Further effectively preventing the terminal assembly from assembling the unsuitable keypad.

The present invention further provides a method for detecting and adapting a terminal and a keypad. Referring to FIG. 5, FIG. 5 is a schematic flowchart of a first embodiment of a method for detecting a terminal and a keypad.

In this embodiment, the method for detecting the adaptation of the terminal and the keypad includes the following steps:

Step S10, outputting a preset voltage detection signal to the terminal;

Step S20, the terminal queries and feeds back a key value corresponding to the voltage value of the voltage detection signal;

In this embodiment, before the terminal is assembled with the keypad, the adaptation detecting device for the terminal and the keypad is described in the foregoing apparatus embodiment of the present invention (hereinafter referred to as an adaptation detecting device), which is used by the present invention. The method for detecting the adaptation of the terminal and the keypad is to detect whether the terminal and the keypad are adapted. As shown in FIG. 1, the adaptation detecting device is connected between the terminal control chip and the keypad. The terminal includes, but is not limited to, a device with a button such as a television or a mobile phone. When each terminal is in production, the manufacturer sets a corresponding voltage interval for the key value of each function button of the terminal. Since different manufacturers have different setting standards for the voltage ranges corresponding to the key values, that is, the voltage intervals corresponding to each key value are currently not uniformly specified. For example, the voltage range corresponding to the key value of the "increase volume" function button in one terminal is 0-0.5v, and the voltage range corresponding to the key value of the "increase volume" function button in another terminal is 0.2-0.8. v. Therefore, it is necessary to determine the voltage interval corresponding to each key value of the terminal.

In this embodiment, the adaptation detecting device acquires a voltage interval corresponding to each key value of the terminal by using a voltage detection signal. Specifically, the adaptation detecting means outputs the preset respective voltage detection signals to the terminal. The terminal stores a preset relationship between the key value and the voltage value. When the terminal receives the voltage detection signal output by the adaptation detecting device, the terminal queries the preset key value and voltage value relationship table to query whether there is a key value corresponding to the voltage value of the voltage detection signal. For example, if the preset key value and voltage value relationship table is a correspondence table between the key value and the voltage interval, the terminal queries the received voltage detection signal in the correspondence table between the key value and the voltage interval. Whether the voltage value is within a voltage range corresponding to a certain key value. When it is queried that the voltage value of the voltage detection signal is within a voltage interval corresponding to a certain key value, that is, the key value corresponding to the voltage value of the voltage detection signal is queried; otherwise, the voltage is not queried. The key value corresponding to the voltage value of the detection signal. When the terminal queries the key value corresponding to the voltage value of the voltage detection signal, the queried key value is fed back to the adaptive detection device, that is, the key value corresponding to the voltage value of the voltage detection signal is fed back to the Adapt the detection device. When the terminal does not query the key value corresponding to the voltage value of the voltage detection signal, that is, when the voltage value of the voltage detection signal does not have a corresponding key value, the terminal feeds back the invalid value to the adaptation detecting device.

Step S30, determining, according to each received key value and a voltage value of the corresponding voltage detection signal, a voltage interval corresponding to each key value and saving;

After each output of a voltage detection signal to the terminal, the adaptation detecting device receives the key value fed back by the terminal or receives an invalid value fed back by the terminal. Wherein, the adaptation detecting device outputs a plurality of voltage detection signals, and the terminal may feed back the same key value, that is, the adaptation detecting device may receive the terminal to feedback the same key value multiple times. The adaptation detecting means determines the voltage interval corresponding to each key value according to the key value received each time and the voltage value of the voltage detection signal corresponding to each received key value, and saves. For example, if the voltage value of the five voltage detection signals corresponds to the key value of the “increase volume” function button, the adaptation detecting device determines the key value corresponding to the “increase volume” function button according to the voltage values of the five voltage detection signals. The voltage interval is saved; if the voltage value of the eight voltage detection signals corresponds to the key value of the “decrease volume” function button, the adaptation detecting device determines the “decrease volume” function button according to the voltage values of the eight voltage detection signals. The voltage range corresponding to the key value is saved.

Step S40, detecting whether there is a button signal triggered by the keypad, and acquiring a voltage value corresponding to the button signal when the button signal is detected;

After determining the voltage interval corresponding to each key value of the terminal, the adaptation detecting device then acquires the voltage value corresponding to each button of the keypad. The following takes the button on the button as an example to describe the voltage value corresponding to the button. When the user presses a button on the keypad, a button signal corresponding to the button is generated, and the button signal is transmitted to the adaptation detecting device. The adaptation detecting device detects whether there is a button signal triggered by the keypad, and when detecting the button signal, the adaptation detecting device acquires a voltage value corresponding to the button signal.

Step S50, determining a positional relationship between a voltage value corresponding to the button signal and any of the voltage intervals, and determining, according to the positional relationship, whether the terminal is adapted to the keypad.

After obtaining the voltage value corresponding to the button signal, the adaptation detecting device compares the voltage value corresponding to the button signal with the voltage interval corresponding to each key value of the saved terminal, and determines the voltage value corresponding to the button signal and saves The positional relationship of the voltage interval corresponding to each key value of the terminal, and determining whether the terminal is adapted to the keypad according to the determined positional relationship. Specifically, the step S50 includes:

Step a, comparing a voltage value corresponding to the button signal with any of the voltage intervals to determine a positional relationship between a voltage value corresponding to the button signal and the voltage interval;

Step b, the voltage value corresponding to the button signal does not belong to any voltage interval or the voltage value corresponding to the button signal belongs to one of the voltage ranges but the difference from the threshold voltage value of the voltage interval is less than the preset voltage difference. At the threshold, it is determined that the terminal is not adapted to the keypad.

In this embodiment, the adaptation detecting device compares the acquired voltage value with a voltage interval corresponding to each key value of the saved terminal, and determines whether the obtained voltage value belongs to a certain key value of the terminal. Voltage range. If the obtained voltage value does not belong to a voltage interval corresponding to any button of the saved terminal, that is, for the terminal, the button corresponding to the button signal is invalid, and the adaptation detecting device determines the terminal. Not compatible with the keypad.

If the adaptive detection device determines that the acquired voltage value belongs to a voltage interval corresponding to a certain button of the saved terminal, the adaptation detecting device further calculates each of the obtained voltage values corresponding to the key value. The absolute difference of the threshold voltage values. Generally, the voltage interval corresponding to the key has two threshold voltage values, and the adaptive detecting device respectively calculates the absolute difference between the obtained threshold voltage values of the voltage interval corresponding to the key value. In this embodiment, a preset voltage difference threshold is set in advance, and the preset voltage difference threshold is flexibly set according to actual conditions, and is not limited herein. In the calculated absolute difference between the voltage value and the threshold voltage value of the voltage interval corresponding to the key value, it is determined whether the absolute difference value is smaller than the preset voltage difference threshold. If there is a certain absolute difference that is less than the preset voltage difference threshold, that is, the voltage value corresponding to the button signal is close to the threshold voltage value of the voltage interval corresponding to the key value. In this case, the The key value is the key value of the button corresponding to the button signal, and therefore, the adaptation detecting means determines that the terminal is not adapted to the keypad. If there is no absolute difference value that is less than the preset voltage difference threshold, that is, the absolute difference between any obtained threshold voltage value of the voltage value corresponding to the key value is greater than or equal to The preset voltage difference threshold is used by the adaptation detecting device to determine that the key value is the key value of the button corresponding to the button signal.

The solution proposed in this embodiment determines the terminal according to each key value fed back by the terminal and the voltage value of each corresponding voltage detection signal after the terminal detects the button board and outputs each preset voltage detection signal to the terminal. The voltage interval corresponding to each key value is saved, and then when the user presses a button on the keypad, when detecting a button signal triggered by the keypad, the adaptation detecting device acquires a voltage value corresponding to the button signal, and corresponding to the button signal according to the button signal The positional relationship between the voltage value and the voltage interval determines whether the terminal and the keypad are adapted. Therefore, it is timely detected whether the terminal and the keypad are adapted before the button panel of the terminal is assembled, so as to be rectified when the detection is not adapted. Therefore, the terminal board is effectively prevented from being assembled with an unsuitable keypad.

Further, with reference to FIG. 6, a second embodiment of the method for detecting the adaptation of the terminal and the keypad is proposed based on the first embodiment. In this embodiment, the step S30 includes:

Step S31, when receiving the key value corresponding to the voltage detection signal fed back by the terminal, correlating the voltage value of the voltage detection signal with the received key value;

Step S32, when the voltage detection signal output is completed, counting a maximum voltage value and a minimum voltage value among the plurality of voltage values associated with the respective key values;

Step S33, determining a voltage interval corresponding to each key value according to the maximum voltage value and the minimum voltage value corresponding to the respective key values.

In this embodiment, the adaptation detecting means associates the key value with the voltage value of the voltage detection signal each time the key value corresponding to the terminal feedback voltage detection signal is received. When the output voltage detection signal is completed, the adaptive detecting device counts a plurality of voltage values associated with the respective key values, and obtains a maximum voltage value and a minimum voltage value associated with the respective key values from the plurality of voltage values associated with the respective key values. Then, according to the maximum voltage value and the minimum voltage value associated with each key value, the voltage interval corresponding to each key value is determined. For example, if the maximum voltage value associated with a certain key value of the statistical acquisition terminal is 0.56v and the associated minimum voltage value is 0.12v, the adaptation detecting device determines that the voltage interval corresponding to the key value is [0.12, 0.56] v.

In this embodiment, each preset voltage detection signal output by the adaptation detecting device is a level signal whose voltage value starts from 0V and sequentially increases according to a preset unit, for example, a level sequentially increased according to an increasing law of 0.01V. signal. The adaptive detecting means detects the voltage value of the voltage detecting signal after each time the voltage detecting signal is output. When detecting the voltage value of the voltage detection signal, the adaptation detecting means determines whether the voltage value of the voltage detection signal is greater than or equal to a preset voltage threshold. For example, if the preset voltage threshold is preset to be equal to the power supply voltage, the adaptation detecting means determines whether the voltage value of the voltage detection signal is greater than or equal to the power supply voltage. When the voltage value of the voltage detection signal is less than the preset voltage threshold, the adaptive detection device continues to output the voltage detection signal. When the voltage value of the voltage detection signal is greater than or equal to the preset voltage threshold, the adaptive detecting device stops outputting the voltage detection signal, that is, the voltage detection signal output is completed.

Further, in this embodiment, the adaptation detecting device further includes a display screen. The display screen may be an LCD liquid crystal display, which is not limited herein. When the adaptation detecting device determines the voltage interval corresponding to each key value of the terminal, and obtains the voltage value corresponding to the key signal, the voltage value corresponding to each key value of the terminal and the voltage value corresponding to the key signal are displayed through the display screen. And when it is determined that the terminal is not adapted to the keypad, the prompt information that is not adapted is displayed.

In the solution provided by the embodiment, each voltage detection signal output by the adaptation detecting device is a level signal whose voltage value starts from 0V and sequentially increases according to a preset unit until the voltage value of the voltage detection signal is greater than or equal to a preset voltage threshold. , stop output voltage detection signal. By gradually increasing the voltage value of the voltage detection signal, the voltage value corresponding to each key value of the terminal can be accurately determined, thereby accurately obtaining the voltage interval corresponding to each key value, thereby realizing more accurate detection of whether the terminal and the keypad are adapted. Thereby, it is further effectively prevented that the terminal assembly is not adapted to the keypad.
