Fig. 1 shows a schematic structural diagram of an intelligent fire fighting device provided by an embodiment of the present disclosure. As shown in fig. 1, the intelligent fire fighting device comprises a detection module 101 configured to send out binary sequence information upon detection of smoke generation and/or temperature increase in a designated area; the light emitting module 102 is configured to respond to the binary sequence information and sequentially emit visible light signals according to the level signal arrangement sequence in the binary sequence information; the receiving module 103 is configured to receive and analyze the visible light signal, and send alarm information according to the analyzed visible light signal.
In this embodiment, whether smoke is generated in the designated area is detected, the detected smoke concentration may be compared with a preset smoke concentration threshold by detecting the smoke concentration, and if the detected smoke concentration is greater than the smoke concentration threshold, it is determined that smoke is generated in the designated area; whether the temperature in the designated area is increased or not is detected, the temperature value can be detected, the detected temperature value is compared with a preset temperature threshold value, if the temperature value is greater than the temperature threshold value, the temperature in the designated area is increased, the temperature value at the current moment can be detected, the temperature value at the next moment can be detected, the temperature values at the two moments are compared, and if the temperature value at the next moment is higher than the temperature value at the current moment, the temperature in the designated area can be increased.
In this embodiment, the designated area may be a range near an electrical device in the electrical system where a fault is likely to occur or the fault rate is high, and the specific range value is not limited. The visible light signal may be selected from visible light with better penetrating power, for example, one or more of red visible light, yellow visible light and green visible light may be selected as the visible light signal.
In this embodiment, the binary sequence information includes N level signals arranged in a first predetermined order, or N level signals arranged in a second predetermined order, or N level signals arranged in a third predetermined order, where N is a positive integer.
The arrangement order of the first predetermined order, the second predetermined order, and the third predetermined order is not limited herein as long as it is ensured that the arrangement order of the first predetermined order, the second predetermined order, and the third predetermined order is different.
For example, when N is 4, the level signals arranged in the first predetermined order are "1001", the level signals arranged in the second predetermined order are "1010", and the level signals arranged in the third predetermined order are "1100"
According to the embodiment of the disclosure, whether smoke is generated or the temperature is increased in the designated area is detected through the detection module 101, when smoke is generated and/or the temperature is increased, the detection module 101 sends binary sequence information to the light emitting module 102, the light emitting module 102 generates visible light signals in a specific sequence, and the receiving module 103 receives and analyzes the visible light signals to judge whether fire occurs in the electrical device, so that interference to signals in an electrical system is avoided, the occurrence of fire can be timely and effectively detected, and the operation stability of the electrical system is greatly improved.
The detection module 101, the light emitting module 102 and the receiving module 103 are described in detail below with reference to specific embodiments.
In some embodiments, the detection module 101 is specifically configured to emit binary sequence information arranged in a first predetermined order upon detection of smoke generated in the designated area; or when the temperature rise in the designated area is detected, binary sequence information arranged according to a second preset sequence is sent out; or when smoke is detected to be generated in the designated area and the temperature is increased, the binary sequence information arranged according to a third preset sequence is sent out.
In particular, the detection module 101 may include a smoke sensor, a temperature sensor, and a controller. The number of the smoke sensors is one or more, the number of the temperature sensors is one or more, the number of the controllers is one or more, and the smoke sensors and the temperature sensors are respectively connected to the controllers.
Optionally, in order to avoid interference of signal transmission among the smoke sensor, the temperature sensor and the controller to signals in the electrical system, the smoke sensor, the temperature sensor and the controller may be integrated into one module, so as to avoid interference of signals of the electrical system itself caused by signal line connection or wireless communication connection among the three.
It should be noted that the distribution of the smoke sensor and the temperature sensor is not particularly limited as long as the smoke concentration and the temperature in the designated area can be detected. For example, one smoke sensor, one temperature sensor, and one controller may be provided in a specified area, or a plurality of smoke sensors, a plurality of temperature sensors, and a plurality of controllers may be provided in a specified area.
In the embodiment, the smoke sensor is used for detecting the concentration of smoke in the designated area and transmitting a specific value of the smoke concentration to the controller, and the temperature sensor is used for detecting the temperature value in the designated area and transmitting the specific value of the temperature to the controller.
The controller can be pre-configured with a smoke concentration threshold value and a temperature threshold value, and when the smoke concentration in the designated area exceeds the smoke concentration threshold value and/or the temperature value exceeds the temperature threshold value, the controller sends binary sequence information with different arrangement orders according to different conditions.
For example, when the smoke density in the designated area exceeds the smoke density threshold, the controller issues binary sequence information "1001" arranged in a first predetermined order, and at this time, "1001" represents that smoke is generated in the designated area.
For example, when the temperature value in the designated area exceeds the temperature threshold, the controller sends binary sequence information "1010" arranged according to a second predetermined order, and at this time, "1010" represents the temperature increase in the designated area.
For example, when the smoke concentration in the designated area exceeds the smoke concentration threshold and the temperature value exceeds the temperature threshold, the controller sends out binary sequence information "1100" arranged according to a third predetermined sequence, wherein "1100" represents that smoke is generated in the designated area and the temperature is increased.
In some embodiments, the light emitting module 102 is specifically configured to sequentially emit visible light signals in a first predetermined order in response to the binary sequence information arranged in the first predetermined order; or in response to the binary sequence information arranged according to a second predetermined sequence, sequentially emitting visible light signals according to the second predetermined sequence; or in response to the binary sequence information arranged in a third predetermined order, sequentially emitting visible light signals in a third predetermined order.
In this embodiment, the visible light signals include a first light signal and a second light signal, and the colors of the first light signal and the second light signal are different, the sum of the number of the first light signals and the number of the second light signals is equal to the number of level signals in the binary sequence information, the first light signal corresponds to a low level signal or a high level signal, and the second light signal corresponds to a high level signal or a low level signal.
For example, the first light signal corresponds to red visible light and corresponds to a high level, and the second light signal corresponds to yellow visible light and corresponds to a low level. When the binary sequence information is '1001', the visible light signal is 'red yellow red'; when the binary sequence information is '1010', the visible light signal is 'red yellow, red yellow and yellow'; when the binary sequence information is "1100", the visible light signal is "red, yellow and yellow".
Specifically, the light emitting module 102 may include one or more processors and one or more light emitting diodes, and one processor corresponds to two light emitting diodes of different colors.
Optionally, in order to avoid interference of signal transmission between the processor and the light emitting diode to signals in the electrical system, the processor and the light emitting diode may be integrated into one module, so as to avoid interference of signal transmission between the processor and the light emitting diode to signals of the electrical system itself by using signal line connection or wireless communication connection.
Alternatively, to further avoid interference with the signal of the electrical system itself, the detection module 101 and the light emitting module 102 may be integrated into one module.
In this embodiment, the processor is configured to receive the binary sequence information, record an arrangement order of the binary sequence information, and control the light emitting diode to emit light according to the recorded arrangement order.
For example, referring to fig. 2, when the smoke density in the designated area increases, the processor receives binary sequence information "1001" sent by the controller, and at this time, the processor sequentially controls the red light emitting diode, the yellow light emitting diode, and the red light emitting diode to emit light according to the sequence of "1001".
For example, referring to fig. 3, when the temperature in the designated area increases, the processor receives binary sequence information "1010" sent by the controller, and at this time, the processor sequentially controls the red light emitting diode, the yellow light emitting diode, the red light emitting diode and the yellow light emitting diode to emit light according to the sequence of "1010".
For example, referring to fig. 4, when the smoke concentration increases and the temperature increases in a designated area, the processor receives binary sequence information "1100" sent by the controller, and at this time, the processor sequentially controls the red light emitting diode and the yellow light emitting diode to emit light according to the sequence of "1100".
Optionally, there is a waiting time between two adjacent visible light signals for distinguishing between two consecutive visible light signals of the same color.
Optionally, the step length of the visible light signal is configured in advance, if the light emitting diode emits the "red, yellow and yellow" light signal, the light emitting time of the red light emitting diode is two step lengths, and similarly, the light emitting time of the yellow light emitting diode is also two step lengths.
In some embodiments, to ensure effective communication between the light emitting module 102 and the receiving module 103, the visible light signal emitted by the light emitting module 102 can be received by the receiving module 103, and the interrogation signal is emitted before the visible light signal is emitted by the light emitting module 102.
Since a plurality of intelligent internet of things fire fighting devices may be arranged in a designated area, the receiving module 103 in one intelligent internet of things fire fighting device may receive a visible light signal in another intelligent internet of things fire fighting device, and at this time, the light emitting module 102 is required to send out an inquiry signal before sending out the visible light signal, so that the receiving module 103 corresponding to the light emitting module stops receiving the visible light signal in another intelligent internet of things fire fighting device.
Optionally, the difference from the above embodiment is that the light emitting module 102 further includes a green light emitting diode.
The interrogation signal comprises M third optical signals, where M is a positive integer, and the color of the third optical signals is different from the color of the first optical signals and the color of the second optical signals.
For example, when M is 3, the third light signal is green visible light, and the query signal is "green", in which case the light emitting time of the green light emitting diode can be controlled by the set step size.
In some embodiments, the receiving module 103 is specifically configured to receive the visible light signals, correspond the visible light signals to binary sequence information according to a receiving sequence of the visible light signals, and send out alarm information according to the binary sequence information.
Specifically, the receiving module 103 includes converters and alarms, and the number and the setting manner of the converters and the alarms are the same as those in the foregoing embodiments, and are not described herein again.
The converter is used for receiving the visible light signal and corresponding the visible light signal to binary sequence information, and sending alarm information according to the binary sequence information, and the alarm sends out an alarm when receiving the alarm information.
For example, the converter receives the visible light signal and corresponds the visible light signal to binary sequence information arranged according to a first preset sequence, smoke alarm information is generated to the alarm, and the alarm gives an alarm according to the generated smoke alarm information.
For example, the converter receives the visible light signal and corresponds the visible light signal to binary sequence information arranged according to a second preset sequence, temperature rise alarm information is sent to the alarm, and the alarm sends an alarm according to the temperature rise alarm information.
For example, the converter receives the visible light signal and corresponds the visible light signal to binary sequence information arranged according to a third preset sequence, alarm information of smoke generation and temperature rise is sent to the alarm, and the alarm sends an alarm according to the alarm information of smoke generation and temperature rise.
When the converter corresponds the visible light signal to binary sequence information, the following method can be adopted:
when receiving the visible light signal, the visible light signal may be judged by a waiting time between two adjacent visible light signals. For example, when the visible light signal is "red yellow red" (the blank space between two colors represents the waiting time), it may be corresponding to binary sequence information of "1001".
When the visible light signal is received, the visible light signal can be judged according to the step length of the visible light signal. For example, when the visible light signal is "red-yellow" (one color represents one step, e.g., "red-red" is two steps of red visible light), it may be corresponding to binary sequence information of "1100".
The manner of receiving the interrogation signal and corresponding it to binary sequence information before receiving the visible light signal is the same as the above-mentioned manner, and is not described herein again.

in step 501, binary sequence information is sent when smoke generation and/or temperature increase in a designated area is detected.
