Example (b):

as shown in fig. 1, an embodiment of the present application provides a night automatic patrol searchlight apparatus, which includes a processor, a searchlight, a steering module for controlling the steering of the searchlight, and a first detection module for detecting whether a person is present at a warning line;

the searchlight is installed directly over the module that turns to, and the pin and the searchlight of treater are connected, and the output pin and the module that turns to of treater are connected, and first detection module is connected with the input pin of treater.

Specifically, as shown in fig. 1, the module of the device includes a voice broadcast module, a display module, a first detection module, a second detection module, a steering module, a searchlight module, a light intensity detection module, an indicator light module, a power supply module and a key module. Connect each module circuit through the treater, can realize the effect of night automatic patrol and control searchlight with the existing equipment that each module corresponds on the region of a certain management and control, if will turn to on module and searchlight install on the enclosure around a certain management and control region, handle at the wall of the four sides of enclosure 3 meters or 4 meters and draw a warning line, first detection module mountable is in four wall angle departments, can detect whether personnel appear on the warning line like this, thereby carry on subsequent whether trigger the searchlight through the treater and throw light on, and control turns to the module and drives the searchlight and rotate together, thereby shine the personnel in warning line region.

According to the utility model, whether the foreign person exists in the target area is detected through the first detection module, if yes, a signal is sent to the processor, the processor controls the searchlight to be turned on, and controls the steering module to steer to drive the searchlight to move, so that the light is irradiated to the position of the target area where the foreign person exists. Therefore, the difficulty of the on-duty personnel in night on-duty can be effectively relieved, the external personnel entering the wall can be treated in advance, and the method has certain significance for improving the security on-duty work.

In another embodiment of this embodiment, the apparatus further includes a second detection module for detecting whether the duty personnel is on the spot, and the second detection module is connected to the input pin of the processor.

Specifically, the second detection module in this embodiment is an infrared sensor, which can check the presence of the staff on duty, and may also use other modules or circuits with the same detection function. When the on-duty personnel are in the sensing range of the infrared sensor, the high level is output, and when the on-duty personnel leave the sensing range of the infrared sensor, the on-duty personnel quit the high level and output the low level. Full-automatic induction is adopted in the whole process, and the induction range is within 5 meters. The sensor has two triggering modes, namely a non-repeatable triggering mode and a repeatable triggering mode. Non-repeatable triggering mode: after the high level is output by induction, the output will automatically change from the high level to the low level as soon as the delay time is over. The trigger mode can be repeated: after the high level is output by induction, in a delay time period, if a human body moves in the induction range, the output of the human body keeps the high level all the time, and the high level is changed into the low level in a delayed manner until the human body leaves. The second detection module can display the detected on-position condition of the duty personnel by selecting a repeatable triggering mode. The second detection module has an initialization time of about one minute after being powered on, and the sensitivity of the second detection module is low during the initialization time, so that the second detection module needs to be preheated for about one minute to normally work.

R11 is used for changing the voltage of the contact ADC when the resistance value of the photoresistor changes, and the contact ADC is connected to the single chip microcomputer, so that the single chip microcomputer can identify the environment as day or night. If the photoresistor is not connected in series with R11, the voltage at the contact ADC is always 0, and the level of the pin P1.7 will not change. The capacitor C4 acts as a filter. Because the resistance value of the photoresistor is changed greatly, the capacitor can ensure that the circuit is kept stable under the change, and the larger fluctuation of a subsequent circuit is avoided.
