The invention relates to a method for transmitting and configuring an instruction of a sensor, in particular to a method for transmitting and configuring an instruction of a sensor implemented by a light source.

In order to reliably detect the environmental state in the space, and thus effectively and automatically control various devices in the space (such as air conditioning equipment, lighting equipment, etc.), many systems will set various sensors in the space, and then according to each The sensing result of the sensor automatically controls each device (for example, automatically turns off the light when the person is detected to leave, or automatically sets the set temperature of the air conditioner when the temperature rises, etc.).

Please refer to FIG. 1A , which is a schematic diagram of a sensor configuration of the related art. As shown in the figure, a plurality of sensors 2 of the same or different types, such as a Person Detector (PD), a temperature sensor, a humidity sensor, etc., may be disposed in one space 1 for sensing The various materials in the space 1 are measured to facilitate automatic control of each device in the space 1 by the above system.

1B is a schematic diagram of a sensor of the related art. As shown in FIG. 1B, one or more setting switches 21, such as a dip switch, a push button, etc., are generally disposed on the sensor 2. In the related art, if the user wants to set the sensor 2, Mainly, the above setting switch 21 is operated manually to complete the setting of the sensor 2 (for example, reset, set update frequency, set sensitivity, etc.).

However, in order to better sense the state in the space 1, the above-described sensor 2 is generally installed in a place where the user does not easily come into contact (for example, a ceiling). Therefore, when the user wants to set or reset the sensor 2, it is necessary to use a ladder to climb the finger to actually touch the setting switch 21 of the sensor 2, which causes considerable trouble to the user.

In order to reduce the difficulty of setting, the manufacturer usually configures a remote controller 3 to allow the user to remotely set the sensor 2 by the remote controller 3. However, in order to be compatible with the above-mentioned remote controller 3, the sensor 2 needs to have at least a wireless communication function such as infrared, Bluetooth or WiFi, so that the cost of the sensor 2 is increased. Furthermore, in order to purchase the remote controller 3 described above, the user must also pay an additional fee.

A main object of the present invention is to provide a sensor command transmission and configuration method implemented by a light source, which can transmit an instruction to a sensor by switching a surrounding light source, and configure a configuration of the sensor.

In order to achieve the above object, the method of the present invention is applied to a sensor having a light sensing unit. The sensor collects time series data of the surrounding light sources by the light sensing unit, and extracts effective multiple sets of light source switching data therefrom. Next, it is determined whether the plurality of sets of light source switching data match the trigger condition of the pre-storage instruction. If the plurality of sets of light source switching data match the trigger condition of the pre-storage command, the sensor outputs a blinking signal by the display unit thereon, and determines whether to further receive a group of confirmation switching data. If the confirmation switching data is received during the waiting confirmation period, the sensor automatically executes the action corresponding to the corresponding pre-storing instruction.

Compared with the related art, the present invention can be applied to a sensor that does not support any wireless communication function, and does not need to use an additional remote controller, thereby effectively reducing the manufacturing and maintenance cost of the sensor.

DETAILED DESCRIPTION OF THE INVENTION A preferred embodiment of the present invention will be described in detail with reference to the drawings.

The invention discloses a sensor command transmission and configuration method (hereinafter referred to as a configuration method) realized by a light source, and the configuration method is applied to various sensors having a light sensing unit (as shown in FIG. 1A and FIG. 1B). The sensor 2) is shown to transmit a command to the sensor 2 by switching the surrounding light source, and the sensor 2 can be configured.

Specifically, the sensor 2 to which the present invention is applied does not need to have any wireless communication function, and only needs to have a light sensing unit to sense a light source in the environment (ie, the brightness and darkness of the light source can be sensed). Thereby, the present invention can be used by the user to directly perform the above-mentioned command transmission and setting configuration on the sensor 2 by switching the surrounding light source (for example, turning on/off a fluorescent lamp, a chandelier, a desk lamp, or using a flashlight).

Referring to Figure 2, there is shown a flow chart of the configuration of the first embodiment of the present invention. First, the sensor 2 collects ambient light time series data by the light sensing unit thereon, and extracts valid sets of light source switching data therefrom (step S10). In this embodiment, the time series data may be as shown in FIG. 4, and each group of light source switching data is respectively composed of a high potential differential signal (ie, the surrounding light source is turned dark) and a low potential differential signal (ie, The surrounding light source is composed of light to dark (details are detailed later).

It is worth mentioning that each group of light source switching data may be composed of a previous high-potential differential signal and a subsequent low-potential differential signal (ie, first light and then dark), or may be prior A low-potential differential signal is combined with a subsequent high-potential differential signal (ie, first dark and then bright), which is not limited.

Specifically, in this embodiment, the sensor 2 temporarily stores the time series data of the surrounding light sources collected by the buffer (not shown) for a temporary storage time (for example, 3 seconds, 5 seconds), and then The internal algorithm analyzes the temporarily stored time series data to extract valid one or more sets of light source switching data. The update frequency of the buffer data of the sensor 2 may be determined according to the sampling frequency of the light sensing unit, for example, once every 100 milliseconds (ms), once every 200 milliseconds (ms), and the like, and according to the buffer. The update frequency of the data is used to perform the parsing process. In this way, the sensor 2 can be successfully received regardless of the time point at which the user switches the light source to transmit the command.

After step S10, the sensor 2 determines, by an internal processor (not shown), whether the plurality of sets of light source switching data match the trigger condition of the pre-storage command (step S12). If the plurality of sets of light source switching data do not match the triggering conditions of the pre-storage command, the sensor 2 discards the plurality of sets of light source switching data (step S14), and returns to step S10 to follow the update frequency of the buffer data again. The temporary time series data is parsed.

If the plurality of sets of light source switching data match the trigger condition of the pre-storage command, the sensor 2 outputs a blinking signal through the display unit (not shown) (step S16). By outputting the flashing signal, the user can know that the sensor 2 has successfully received an instruction from the user to transmit to the sensor 2 by switching the surrounding light source. In an embodiment, the display unit is a Light Emitting Diode (LED), a light bulb or a display screen, and is flashed by the processor of the sensor 2 .

In one embodiment, the number of blinks of the blinking signal is the same as the number of groups of the plurality of sets of light source switching data. By outputting the blinking signal, the user can further confirm whether the number of sets of light source switching data analyzed by the sensor 2 is correct.

It is worth mentioning that in the present invention, the sensor 2 can pre-store one or more pre-stored instructions, each pre-stored instruction corresponds to a trigger condition, and each trigger condition respectively records a positive integer value. For example, 1, 2, 3, 4, and so on. In the foregoing step S12, the sensor 2 is mainly configured to determine that the plurality of sets of light source switching data are equal to the value recorded by any of the trigger conditions, and determine that the plurality of sets of light source switching data meet the trigger condition of the plurality of light sources. Pre-storage instructions.

For example, if the value of the trigger condition record of the first pre-stored instruction is 3, and the value of the trigger condition record of the second pre-stored instruction is 5, then the user turns on and turns off the surrounding light source three times (ie, the sensor 2 After the analysis, three sets of light source switching data are generated), and the sensor 2 determines that the corresponding pre-storage instruction is the first pre-storage instruction.

Further, after the blinking signal output is completed, the sensor 2 further counts a waiting confirmation period, and judges whether or not a valid set of confirmation switching data is received during the waiting confirmation period (step S18). In this embodiment, the confirmation switching data corresponds to a set of confirmation waveforms defined by the user, and when the sensor 2 waits for the confirmation period, it receives a set of valid switching data, and determines that the waveform of the group switching data conforms to the user. When the waveform is confirmed in advance, the group switching data is used as the group confirmation switching data.

FIG. 8A is a schematic diagram of a confirmation signal according to a first embodiment of the present invention. In the embodiment of Figure 8A, the user sets the confirmation waveform to a set of valid Step Functions. For example, as shown in the first waveform of FIG. 8A, if the sensor 2 confirms that the previous ambient light is relatively dark, as long as a high-potential differential signal is sensed (the ambient light time series is an up-step), it can be considered as A valid confirmation switch data (that is, the valid differential signal for confirming the switch data is a high-potential differential signal).

Taking the second waveform of FIG. 8A as an example, if the sensor 2 confirms that the previous ambient light is relatively bright, as long as a low-potential differential signal is sensed (the ambient light time series is the next step), it can also be determined. Is a valid confirmation switch data (that is, the valid differential signal for confirming the switch data is a low-potential differential signal). As for the other waveforms in FIG. 8A, since the user-defined staircase wave is not met, the sensor 2 does not regard the waveforms as a valid confirmation switching data.

The step wave is only one embodiment of the acknowledgment waveform described in the present invention. In other embodiments, the user can also define the acknowledgment switching data as other types of waveforms.

FIG. 8B is a schematic diagram of a confirmation signal according to a second embodiment of the present invention. In the embodiment of FIG. 8B, the user sets the confirmation switching data as a set of valid Rectangle Functions.

Taking the third waveform in FIG. 8B as an example, if the sensor 2 confirms that the previous ambient light is relatively dark, the sensor 2 will first sense a high-potential differential signal, and then sense it again. When a low-potential differential signal is asserted, it is determined that the received data is a valid confirmation switching data (that is, the valid differential signal of the switching data is determined by the previous high-potential differential signal and the subsequent low-level signal The potential difference signal is composed of).

Taking the fourth waveform in FIG. 8B as an example, if the sensor 2 confirms that the previous ambient light is relatively bright, the sensor 2 first senses a bottom potential difference signal, and then senses When a high-potential differential signal is asserted, it is determined that the received data is a valid confirmation switching data (that is, the differential signal of the valid confirmation switching data is from a previous low-potential differential signal and a subsequent high The potential difference signal is composed of). As for the other waveforms in FIG. 8B, since the user-defined square wave is not met, the sensor 2 does not regard the waveforms as a valid confirmation switching data.

If the sensor 2 does not receive the confirmation switching data during the waiting confirmation period, or the received data is not valid confirmation switching data, the sensor 2 discards the plurality of sets of light source switching data (step S14), And returning to step S10, the parsing time series data is parsed again according to the update frequency.

If the sensor 2 does receive valid confirmation switching data during the waiting confirmation period, the sensor 2 executes a pre-storage instruction corresponding to the plurality of sets of light source switching data by the processor (step S20). In an embodiment, the pre-storage command may be a reset command, a delay time setting command, a sensitivity adjustment command, or the like, but is not limited.

After step S20, the sensor 2 further determines whether or not the power is turned off (step S22), and if the power is turned off, the configuration method of the present invention is ended. And, the sensor 2 repeatedly performs the foregoing step S10 to before the power is cut off. Step S20, to continuously collect the time series data of the surrounding light sources, and determine whether the user transmits the instructions by switching the surrounding light sources.

Please refer to FIG. 3 at the same time, which is an operation timing diagram of the first embodiment of the present invention. Figure 3 is used to further illustrate how the user transmits commands to the sensor 2 by switching the ambient light source. First, the user performs a switching operation of turning on/off the light source around the sensor 2, such as a fluorescent lamp or a desk lamp (step S30), thereby externally transmitting a light command (step S32).

In this embodiment, if the ambient light source is initially turned on, the user turns off the surrounding light source and then turns it on again, which is regarded as a loop (ie, corresponding to a set of light source switching data); if the surrounding light source is initially turned off, the user first Turning the ambient light on and turning it off again is considered a loop (ie, corresponding to a set of light source switching data). In other words, if the user turns on/off the surrounding light source five times, the light command will contain five sets of light source switching data.

After the light command is issued, the sensor 2 can acquire the light command by the light sensing unit, and obtain a corresponding pre-storage command via the foregoing parsing process (step S34). Moreover, the sensor 2 further outputs a blinking signal by the display unit (step S36) as a feedback message (ACK).

Next, the user confirms whether the analysis of the optical command by the sensor 2 is correct by the blinking signal (step S38). In an embodiment, the user confirms whether the number of blinks of the blinking signal is the same as the number of times the user performs the switching operation in step S30. Then, after the number of confirmations is correct, the user turns on/off the surrounding light source again to transmit a confirmation command to the outside (step S40).

After the above step S36, the sensor 2 starts counting for a waiting period. If the confirmation command is received during the waiting confirmation period, the sensor 2 further executes a pre-storage instruction corresponding to the optical command (step S42).

With the configuration method of the present invention, the user does not need to touch the sensor 2 at all, and it is not necessary to purchase an infrared remote controller or a Bluetooth remote controller, and the remote sensor 2 can be easily configured and configured, which is quite convenient.

Referring to FIG. 4, FIG. 4 is a diagram of a handover data analysis according to a first embodiment of the present invention. FIG. 4 is a diagram for explaining how the step S10 of FIG. 2 performs parsing processing on the time series data to obtain one or more sets of light source switching data.

First, the sensor 2 collects time series data of the surrounding light sources through the light sensing unit, and temporarily stores the time series data through the buffer (step S50). As shown in FIG. 4, the time series data includes a light wave change collected and temporarily stored by the buffer during the temporary storage time.

Then, the sensor 2 performs differential encoding on the temporarily stored time series data by the processor to obtain multiple high-potential differential signals and multiple low-potential differential signals as shown in FIG. 4 (step S52). . Specifically, a high-potential differential signal corresponds to a light source turn-on operation (ie, the light source is turned on), and a low-potential differential signal corresponds to a light source turn-off operation (ie, the light source is turned from dark to dark).

Next, the sensor 2 performs filtering processing on the plurality of high-potential differential signals and the plurality of low-potential differential signals (step S54).

Specifically, the sensor 2 records a maximum diffrence (Dmax) and a minimum difference (Dmin). As shown in FIG. 4, the filtering process is to perform signal strength determination on a plurality of high-potential differential signals and a plurality of low-potential differential signals, so as to retain a plurality of strokes between the difference maximum value and the difference minimum value. High potential differential signal and multiple low potential differential signals.

Next, the sensor 2 sequentially records a high-potential differential signal processed by the filtering and an adjacent low-potential differential signal as a set of light source switching data 4 (step S56). Moreover, as shown in FIG. 4, each group of light source switching data 4 does not overlap each other, that is, each group of light source switching data 4 does not include the same high potential difference signal or low potential difference signal.

After step S56, the sensor 2 can extract a plurality of sets of light source switching data 4 from the time series data, and further determine, according to the number of groups of the light source switching data 4, which one of the pre-storage instructions corresponds to the switching operation of the user.

Continuing to refer to FIG. 5, it is a flow chart of the handover data parsing according to the first embodiment of the present invention. FIG. 5 is a diagram for further explaining how the step S10 of FIG. 2 described above performs the parsing process on the time series data.

As shown in FIG. 5, first, the sensor 2 collects and temporarily stores time series data of the surrounding light sources by the light sensor (step S60), and then the sensor 2 performs the aforementioned differential encoding on the temporarily stored time series data. Processing to obtain a plurality of high-potential differential signals and a plurality of low-potential differential signals (step S62).

Next, the sensor 2 obtains a difference threshold value (step S64), and judges whether the difference threshold value is a preset difference minimum value (step S66). Specifically, the sensor 2 obtains a preset difference maximum value as the difference threshold value in step S64.

When the difference threshold is not the minimum value, the sensor 2 determines whether the plurality of high-potential differential signals and the plurality of low-potential differential signals have a plurality of sets of differential signal groups greater than the difference threshold (step S68), Each of the differential signal groups consists of a high-potential differential signal and an adjacent low-potential differential signal.

When it is determined that there are multiple sets of differential signal groups exceeding the difference threshold, the sensor 2 further determines whether the plurality of sets of differential signal groups are respectively valid differential signal groups (step S72).

In the embodiment of FIG. 5, if the sensor 2 determines in step S68 that there are no sets of differential signal groups exceeding the difference threshold value, the sensor 2 lowers the difference threshold value (step S70), and returns Step S66, determining whether the difference threshold value after the down-regulation is a difference minimum value, and determining whether there are multiple sets of differential signal groups exceeding the adjusted difference threshold value after the adjusted difference threshold value is not a small difference value. .

Moreover, if the sensor 2 determines in step S72 that the plurality of sets of differential signal groups are invalid differential signals, the sensor 2 also lowers the difference threshold value (step S70), and returns to step S66 to The difference threshold value after the downgrade is judged again.

Please refer to FIG. 6 at the same time, which is a schematic diagram of signal processing according to the first embodiment of the present invention. In an embodiment, the difference maximum value Dmax may be a brightness maximum value or a darkness maximum value that the light sensing unit of the sensor 2 can sense, and the aforementioned difference minimum value Dmin is a predefined one. The absolute value of the differential signal of the source switching can be distinguished.

As shown in FIG. 6, the sensor 2 analyzes the temporarily stored time series data D1 to extract a plurality of high-potential differential signals S1 and a plurality of low-potential differential signals S2. Next, starting from the difference maximum value Dmax (ie, setting the difference maximum value Dmax to the aforementioned difference threshold value), it is determined whether there is one or more sets of differential signal groups whose signal strength exceeds the difference threshold value. If one or more sets of differential signal groups whose signal strength exceeds the difference threshold value is not found, the sensor 2 lowers the difference threshold value and re-determines until the difference threshold value after the down-regulation is the difference minimum value Dmin.

If it is determined that one or more sets of differential signal groups whose signal strength exceeds the difference threshold value is determined before the difference threshold value is adjusted to the difference minimum value, the sensor 2 further determines whether the one or more sets of differential signal groups are valid. The differential signal group (ie, performing the aforementioned step S72 of FIG. 5).

As shown in FIG. 6, there is a time interval between two adjacent differential signals, and the time interval I1 is a time interval for the user to control the on/off of the surrounding light source. In one embodiment, the sensor 2 determines that the one or more sets of differential signal groups are effective differentials when the time interval I1 between the respective high-potential differential signals S1 and the adjacent low-potential differential signals S2 is stable. Signal group. Specifically, when the plurality of time intervals I1 in the temporarily stored time series data D1 are the same or similar, the sensor 2 determines that the time intervals I1 are stable.

In another embodiment, the sensor 2 is that the plurality of time intervals I1 in the temporarily stored time series data D1 are greater than a preset minimum interval and less than a preset maximum interval (maximum interval). And determining that the one or more sets of differential signal groups are valid differential signal groups.

Please refer to FIG. 7A and FIG. 7B simultaneously, which are respectively schematic diagrams of the operation interval between the first embodiment and the second embodiment of the present invention. The time interval I1 described above is a time interval for the user to control the on/off of the surrounding light source, that is, the time interval of the light/dark switching sensed by the sensor 2 by the light sensing unit.

In the embodiment of FIG. 7A, the time interval between the ambient light source switching from bright to dark is 0.5 seconds (the time when the light source is bright is maintained for 0.5 seconds, that is, the time interval I1 is 0.5 seconds), and the surrounding light source is similarly The time interval for dark switching to bright is also 0.5 seconds (representing that the light source is dark for 0.5 seconds). In the embodiment of FIG. 7B, the time interval between the ambient light source switching from bright to dark is 1 second (the time when the light source is bright is maintained for 0.5 seconds, that is, the time interval I1 is 1 second), and the surrounding light source is similarly The time interval between dark switching and bright is also 1 second (representing that the time when the light source is dark is maintained for 1 second).

With the configuration method of the present invention, the user only needs to complete the switching operation of the surrounding light source within the temporary storage time supported by the buffer of the sensor 2, and the time interval I1 is stabilized. The light command is transmitted to the sensor 2. Therefore, each user can use different time intervals to switch the surrounding light source, which effectively improves the flexibility of use of the present invention.

Please refer to Figure 6 again. In the time series data D1 temporarily stored in the sensor 2, in addition to the plurality of high-potential differential signals S1 and the plurality of low-potential differential signals S2, a start time (setup time) before the first differential signal is included. ) T1, and a sleep time T2 after the last differential signal. In still another embodiment, the sensor 2 determines the one or more sets of differential signals when the startup time T1 is greater than a preset threshold activation time, and the sleep time T2 is greater than a preset threshold sleep time. The group is a valid differential signal group.

Referring back to FIG. 5, if the sensor 2 determines in the foregoing step S72 that the one or more sets of differential signal groups are valid differential signal groups, the sensor 2 may record the one or more sets of valid differential signal groups as The plurality of sets of light sources switch data (step S76). As shown in FIG. 4 and FIG. 6, each group of light source switching data does not overlap each other (that is, each group of light source switching data does not include the same high potential difference signal S1 or low potential difference signal S2).

In this embodiment, after determining that the one or more sets of differential signal groups are valid differential signal groups, the sensor 2 may further record one or more high potential differences in the one or more sets of differential signal groups. The positive difference value of the signal S1 and the negative differential value of the one or more low potential differential signals S2 (step S74). By facilitating the sensor 2, when receiving the subsequent data, it is determined whether the data is sent by the user and validly confirms the switching data (detailed later).

Referring to FIG. 8A and FIG. 8B, as described above, the sensor 2 waits for an acknowledgement period after the blinking signal is issued, and if the valid confirmation switching data is received during the waiting confirmation period, the plurality of sets of light sources can be further executed. Switch the pre-storage instructions corresponding to the data.

In the embodiment of FIG. 8A and FIG. 8B, the confirmation switching data can be defined by the user, and is a single-acknowledgment high-potential differential signal (step wave), a single-acknowledgment low-potential differential signal (step wave), or A confirmation high-potential differential signal and a confirmation low-potential differential signal (square wave) are not limited. That is to say, during the waiting confirmation period, the user performs at least one on or off switching operation on the surrounding light source. However, the above-mentioned one-time opening or closing switching operation is only one specific embodiment, and the user can set the sensor 2 according to actual needs, and the number of switching operations is not limited to one time.

As described above, the sensor 2 can record the positive differential value of the plurality of high-potential differential signals of the plurality of sets of differential signal groups and the negative of the plurality of low-potential differential signals after determining that the plurality of sets of differential signal groups are valid differential signal groups. Differential value. In one embodiment, the sensor 2 is the same or similar to the positive difference value of the confirmed high potential differential signal and the positive differential value of the recorded plurality of high potential differential signals, or the confirmation low potential differential signal When the negative difference value is the same as or similar to the negative difference value of the recorded plurality of low-potential differential signals, it is determined that the confirmation switching data is valid confirmation switching data.

Moreover, as shown in FIG. 8A and FIG. 8B, when the number of switching operations is different from the preset number of times of the sensor 2, the switching operation time is earlier than the waiting confirmation period, and the user does not perform the switching operation during the waiting confirmation period. Or confirm the positive difference value of the high potential differential signal in the switching data/confirm the negative difference between the negative differential value of the low potential differential signal and the positive differential value/low potential difference signal of the high potential differential signal recorded by the sensor 2. When the values are different, the sensor 2 determines that the confirmation switching data is invalid confirmation switching data.

With the configuration method of the present invention, the user can set the sensor by switching the surrounding light source without using an additional remote controller or setting any wireless communication unit on the sensor, thereby effectively reducing the configuration of the sensor. The manufacturing and maintenance costs of the sensor.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, equivalent changes to the scope of the present invention are included in the scope of the present invention. Bright.
