In order to solve the technical problem, an embodiment of the utility model provides an analog camera and monitored control system. First, an analog camera according to an embodiment of the present invention will be described in detail.

By applying the embodiment shown in fig. 1 of the present invention, the analog camera comprises a sensing signal receiving chip, the sensing signal receiving chip comprises an electromagnetic receiving antenna and a processor, the electromagnetic receiving antenna receives the electromagnetic wave transmitted by the wireless transmitting sensor, the processor converts the electromagnetic wave into a digital sensing signal, and the video conversion chip in the analog camera controls the alarm to alarm according to the digital sensing signal and/or the digital alarm signal transmitted by the server; therefore, on the first aspect, the sensing signals transmitted by the wireless transmitting sensor are received and processed in the analog camera; in the second aspect, the analog camera in the scheme controls the alarm contained in the analog camera to alarm according to the sensing signal and/or the alarm signal sent by the server, so that the alarm function is realized.
The wireless transmitting sensor can be smoke sensing equipment, temperature sensing equipment, humidity sensing equipment, PIR pyroelectric infrared sensors and the like, and is not limited specifically. Correspondingly, the electromagnetic waves emitted by the wireless emission sensor can carry smoke information, temperature information, humidity information, thermal infrared information and the like. After the electromagnetic wave is received by the electromagnetic receiving antenna 1301, the processor 1302 converts the electromagnetic wave into a digital sensing signal and sends the digital sensing signal to the video conversion chip 140.
The video conversion chip 140 receives the digital sensing signal and also receives a digital alarm signal sent by the server. Specifically, the video conversion chip 140 converts a Bayer image signal sent by the sensor into a digital image signal, converts the digital image signal into an analog image signal, sends the analog image signal to the server, converts the analog image signal into a digital image signal after the server receives the analog image signal, analyzes the digital image signal, and sends a digital alarm signal to the analog camera 10 when an analysis result meets a preset alarm condition.
The video conversion chip 140 controls the alarm 150 to alarm according to the digital sensing signal and/or the digital alarm signal. The alarm may be a flashing light, a buzzer, etc., and correspondingly, the alarm mode may be a flashing light, a buzzer, etc., and is not limited specifically.
The specific control method is various, such as:
in the first way, the video conversion chip 140 can control the alarm 150 to alarm when receiving the digital alarm signal; in the second mode, after the video conversion chip 140 receives the digital sensing signal, the digital sensing signal is subjected to data analysis, and the alarm 150 is controlled to alarm when the analysis result meets the alarm condition; in the third mode, the video conversion chip 140 matches the digital sensing signal with the digital alarm signal, and controls the alarm 150 to alarm if the matching is successful.
In the second mode, a memory 180 may be disposed in the analog camera, as shown in fig. 2, the memory 180 is connected to the video conversion chip 140, the memory 180 stores alarm configuration parameters, the video conversion chip 140 performs data analysis on the digital sensing signal after receiving the digital sensing signal, obtains an analysis result, reads the alarm configuration parameters from the memory 180, and controls the alarm 150 to alarm when the analysis result matches the alarm configuration parameters.
Matching may also be understood as, for example, a PIR pyroelectric infrared sensor detecting a living object and acquiring a thermal infrared value of the living object. Comparing the thermal infrared value with the alarm configuration parameter, and if the difference between the thermal infrared value and the alarm configuration parameter is an allowable error, indicating that the analysis result is matched with the alarm configuration parameter; for example, if the smoke detector detects the change of smoke concentration in the monitoring environment and outputs a voltage value, the voltage value output by the smoke detector is compared with the alarm configuration parameters, and if the voltage value is found to be closer to the first-level alarm parameter, the analysis result is matched with one of the alarm configuration parameters, and the details are not limited.
For another example, if the wireless transmission sensor is a temperature sensing device, and the electromagnetic wave transmitted by the wireless transmission sensor carries temperature information, a temperature threshold may be preset, and the temperature threshold is stored in the memory 180 as an alarm configuration parameter. After the electromagnetic wave is received by the electromagnetic receiving antenna 1301, the processor 1302 converts the electromagnetic wave into a digital sensing signal, the video conversion chip 140 analyzes the digital sensing signal to obtain the temperature information represented by the digital sensing signal, reads the temperature threshold value from the memory 180, determines whether the temperature information reaches the temperature threshold value, and controls the alarm 150 to give an alarm if the temperature information reaches the temperature threshold value.
Or, the electromagnetic wave emitted by the wireless emission sensor may also carry humidity information, smoke information, infrared information, and the like, and the corresponding set humidity threshold, smoke content threshold, infrared information related parameters, and the like may be stored in the memory 180 as alarm configuration parameters. The alarm process is similar to the above example and will not be described again.
In the third mode, the video conversion chip 140 may match the digital sensing signal with the digital alarm signal in various ways. Continuing the above example, the wireless transmitting sensor is a temperature sensing device, the electromagnetic wave transmitted by the wireless transmitting sensor carries temperature information, after the electromagnetic receiving antenna 1301 receives the electromagnetic wave, the processor 1302 converts the electromagnetic wave into a digital sensing signal, the video conversion chip 140 analyzes the digital sensing signal to obtain temperature information represented by the digital sensing signal, and reads the temperature threshold from the memory 180 to determine that the temperature information reaches the temperature threshold; in this case, if the video conversion chip 140 does not receive the alarm signal sent by the server within the preset time period in which the determination result is obtained, the matching between the sensing signal and the alarm signal fails, and no alarm is given.
If the video conversion chip 140 receives a digital alarm signal sent by the server within a preset time period in which the determination result is obtained, the digital alarm signal may carry specific alarm information, and if the alarm signal carries information that the ambient temperature is too high or similar, the digital sensing signal and the digital alarm signal are successfully matched, and the video conversion chip 140 controls the alarm 150 to alarm. Matching may also be understood as meaning that both the sensor signal and the alarm signal of the server indicate that an alarm event has occurred, indicating that the match was successful.
It can be understood that if the video conversion chip 140 controls the alarm process according to the digital sensing signal, the server sends the digital alarm signal according to the analog image signal, and an error occurs in one of the two processes, the third method is utilized, so that the situation of false alarm does not occur.

Comparing the thermal infrared value with the alarm configuration parameter, and if the difference between the thermal infrared value and the alarm configuration parameter is an allowable error, indicating that the analysis result is matched with the alarm configuration parameter; for example, if the smoke detector detects the change of smoke concentration in the monitoring environment and outputs a voltage value, the voltage value output by the smoke detector is compared with the alarm configuration parameters, and if the voltage value is found to be closer to the first-level alarm parameter, the analysis result is matched with one of the alarm configuration parameters, and the details are not limited.
For another example, if the wireless transmission sensor is a temperature sensing device, and the electromagnetic wave transmitted by the wireless transmission sensor carries temperature information, a temperature threshold may be preset, and the temperature threshold is stored in the memory 180 as an alarm configuration parameter. After the electromagnetic receiving antenna 1301 receives the electromagnetic wave, the processor 1302 converts the electromagnetic wave into a digital sensing signal, the control chip 1402 analyzes the digital sensing signal to obtain the temperature information represented by the digital sensing signal, reads the temperature threshold from the memory 180, determines whether the temperature information reaches the temperature threshold, and if the temperature information reaches the temperature threshold, controls the alarm 150 to give an alarm.
Or, the electromagnetic wave emitted by the wireless emission sensor may also carry humidity information, smoke information, infrared information, and the like, and the corresponding set humidity threshold, smoke content threshold, infrared information related parameters, and the like may be stored in the memory 180 as alarm configuration parameters. The alarm process is similar to the above example and will not be described again.
In the third mode, the control chip 1402 may match the digital sensing signal with the digital alarm signal in various ways. Continuing the above example, the wireless transmission sensor is a temperature sensing device, the electromagnetic wave transmitted by the wireless transmission sensor carries temperature information, after the electromagnetic receiving antenna 1301 receives the electromagnetic wave, the processor 1302 converts the electromagnetic wave into a digital sensing signal, the control chip 1402 analyzes the digital sensing signal to obtain temperature information represented by the digital sensing signal, reads the temperature threshold from the memory 180, and determines that the temperature information reaches the temperature threshold; in this case, if the control chip 1402 does not receive the alarm signal sent by the server within the preset time period in which the determination result is obtained, the sensing signal and the alarm signal are not matched, and no alarm is given.
