Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
According to an embodiment of the present invention, a monitoring device control method is provided, as shown in fig. 1, including:
step 101: a sending end receives an original signal input by a user;
specifically, a sending end receives an original signal input by a user through key operation; or, the transmitting end receives the original signal input by the user through the Bluetooth function.
For example, when the user finds that the time on the monitoring device is inaccurate, a raw signal for correcting the time is input to the transmitting end by operating a key or through a bluetooth function.
Step 102: the sending end converts the received original signal and sends a corresponding optical signal to the photoresistor according to the conversion result;
according to the embodiment of the invention, the method for converting the received original signal by the sending end comprises the following steps:
step A1: the method comprises the steps that a sending end modulates received original signals according to a first preset method to obtain data in a preset form;
the first preset method is preferably a binary modulation method; correspondingly, the data in the preset form is a binary data string;
specifically, the received original signal is serialized and expanded into a binary data string, for example, the original signal is 55h in hexadecimal, and the modulated binary data string is 01010101.
Step A2: and the sending end modulates the obtained data in the preset form according to a second preset method to obtain a corresponding optical intensity value.
The second preset method is preferably an OOK (On-Off Keying) modulation method;
specifically, each bit in the binary data string is operated with the optical intensity value, if the operation result is symbol 0, the optical intensity value becomes a0, and if the operation result is symbol 1, the optical intensity value becomes a1, thereby obtaining the optical intensity value corresponding to the binary data string; note that a0 differs greatly from a1 for ease of comparison.
Correspondingly, in step 102, the corresponding optical signal is sent to the photoresistor according to the conversion result, specifically: and according to the obtained change of the optical intensity value, continuously sending corresponding optical signals to the photoresistors in different time periods respectively.
For example, the optical signal corresponding to the symbol 0 is continuously transmitted according to the optical intensity variation value A0 for a period T0 (unit: ms), and the optical signal corresponding to the symbol 1 is continuously transmitted according to the optical intensity variation value A1 for a period T1 (unit: ms).
In the invention, because the signal received by the photoresistor is usually an analog signal, and the data collected by the photoresistor is the intensity of the light intensity irradiated to the photosensitive surface of the photoresistor, the representation is a continuously-changed analog signal, usually two characteristic representation values, a time axis and an amplitude value, for example, natural light in the daytime and at night has great difference on the light intensity, the current environment can be distinguished through the representation, so that the equipment is informed of corresponding mode switching, or when the environment for installing the equipment is poor, the daytime and the night can be switched through the representation, and pictures and video contents can be captured. However, since the light intensity change of natural light is usually very slow, and the light intensity change is only obvious when the light intensity is switched between day and night, in order to transmit a special original signal, the original signal is converted into modulated light which is modulated by binary system, and then the modulated light is transmitted to the photosensitive surface of the photoresistor, so that the photoresistor demodulates the original signal, and the monitoring equipment is controlled.
To further illustrate the difference between the optical signal without binary modulation and the optical signal after binary modulation, the present invention provides a comparison graph of the optical signal, as shown in fig. 2 and fig. 3, it can be seen that the optical signal without binary modulation in fig. 2 is difficult to demodulate a useful signal therefrom; for the binary modulated optical signal in fig. 3, it can be seen that the high frequency part and the low frequency part are very obvious, and if the high frequency part is denoted as "1" and the low frequency part is denoted as "0", the optical signal can be demodulated to obtain 01010101, i.e. 55h in hexadecimal.
Step 103: the photoresistor analyzes the received optical signals and sends corresponding control instructions to the monitoring equipment according to the analysis result.
According to the embodiment of the present invention, the photoresistor analyzes the received optical signal, specifically: the photoresistor demodulates the received optical signal to obtain data in a preset form; and demodulating the obtained data in the preset form to obtain an original signal.
For example, the photoresistor demodulates the received optical signal to obtain a binary data string 01010101, which is demodulated to obtain the original signal 55 h.
Optionally, in the present invention, the sending of the corresponding control instruction to the monitoring device according to the analysis result specifically includes: and sending the original signal obtained by analysis to the monitoring equipment, or sending a corresponding control instruction to the monitoring equipment according to the obtained original signal.
Wherein, send corresponding instruction to supervisory equipment according to the original signal that obtains, specifically: and sending a corresponding control instruction to the monitoring equipment according to the obtained original signal and a preset control protocol and control instruction.
Further, according to the embodiment of the present invention, before step 101, the method further includes:
and B: sending different optical signals to the photoresistor through the sending end, collecting and analyzing the optical signals and noise received by the photoresistor, and forming a characteristic value parameter library;
according to the embodiment of the present invention, step B specifically includes:
step B1: the sending end sends the modulated optical signal to the photoresistor and collects a first optical signal and a first noise period variable quantity received by the photoresistor;
step B2: the sending end sends an unmodulated optical signal to the photoresistor and collects a second optical signal and a second noise period variable quantity received by the photoresistor;
step B3: respectively counting the time lengths occupied by the high-frequency part and the low-frequency part in the first optical signal and the second optical signal to obtain the overall distribution values of the time lengths in different environments;
the overall distribution value of the time length is the time length occupied by the symbol 0 and the symbol 1 under various environments.
Step B4: analyzing the first noise period variation and the second noise period variation to obtain noise period variation distribution under different environments;
step B5: and respectively iterating the obtained integral distribution value of the time length and the obtained noise period change distribution to obtain a characteristic value parameter library.
The execution sequence of the step B1 and the step B2 can be interchanged, and the execution sequence of the step B3 and the step B4 can be interchanged.
Further, after obtaining the feature value parameter library, the method further includes: and respectively presetting the characteristic value parameter library into the transmitting end and the photoresistor.
Correspondingly, in step 102, the corresponding optical signal is sent to the photoresistor according to the conversion result, specifically: sending corresponding optical signals to the photoresistor according to a preset characteristic parameter library and a conversion result;
correspondingly, in step 103, the photoresistor analyzes the received optical signal, specifically: and the photoresistor performs anti-noise analysis and demodulation on the received optical signals according to a preset characteristic parameter library.
In the invention, because the optical signal has interference in the transmission process, the time window of the optical signal received by the photoresistor does not necessarily correspond to the time period T0 or T1, and the anti-noise analysis is required to be carried out on the received optical signal; and the anti-noise analysis is carried out on the received optical signals according to a preset characteristic parameter library, so that the analysis is more accurate, and the monitoring equipment can be accurately controlled.
Furthermore, in the present invention, after step 103, the method further includes: and the monitoring equipment executes corresponding operation according to the received control instruction.
In the invention, the monitoring equipment executes corresponding operations according to the received control instruction, including but not limited to execution time correction operation, import configuration operation and output monitoring picture operation according to the received control instruction.
Therefore, the original signal input by a user is modulated by the sending end, and the modulated optical signal is demodulated by the photosensitive electrons, so that the effective control of the monitoring equipment in a short distance is realized.
