The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The applicant has found that it is not possible to whistle, i.e. sound, with an alarm at certain times (such as nights or high-examination hours) or in certain locations (areas with a relatively high flow of people) of many scenes according to relevant regulations. The alarm in special equipment (such as a fire truck and an ambulance) has two alarm modes of sound alarm and alarm light prompt alarm, and the alarm in the prior art has three working states, namely a closed state, an open state and a trigger state, wherein the closed state means that the alarm is closed, and neither sound alarm nor alarm light alarm is performed. The on state is that sound and warning light alarm are simultaneously executed. The triggering state can be executed only by manually touching a triggering part on the alarm, but no matter the working state of the alarm, the alarm cannot be flexibly executed according to different specific places or specific time.
FIG. 1 is a flow chart of the alarm method of the present invention. As shown in fig. 1, in one embodiment, the present application provides an alarm method, comprising:
s101, the alarm can acquire surrounding environment information through a sensor, wherein the environment information comprises obstacle information and position information;
in this step, a specific embodiment is provided in which the alarm obtains the environmental information and the location information through the sensor. It should be noted that the position information may be obtained by the sensor or may be calculated by a processor provided in the alarm. For example, it is known that the alarm is mounted on the special vehicle, and the initial departure point of the special vehicle can obtain the position of the special vehicle, that is, the position information, through the traveling path of the special vehicle. Still alternatively, the position information may be determined by acquiring surrounding landmarks or the like by the sensor.
S201, the alarm judges whether an obstacle exists according to the obstacle information, if so, judges whether the obstacle is a vehicle or a pedestrian, if so, judges whether the area can be subjected to sound alarm according to the prestored alarm-capable area plan according to the position information, if so, judges whether the current time can be subjected to sound alarm according to the prestored alarm-capable time plan of the area, and if so, executes the sound alarm.
In this step, a specific embodiment of making the alarm according to the obstacle information and the position information is provided. In this step, the alarm determines whether the obstacle exists according to the obstacle information, and if the obstacle exists, the alarm determines whether the obstacle is the vehicle or the pedestrian according to whether the obstacle can move. Only when the barrier is the vehicle or the pedestrian, can only take effect when the alarm reports to the police, because only drive the people of vehicle or the pedestrian can only by the alarm is influenced, notices the alarm avoids or dodges. It should be noted that the identification of the vehicle or the pedestrian can be realized by means of image identification, which can be easily performed by those skilled in the art, and therefore, the details are not repeated herein. And if the barrier is a vehicle or a pedestrian, judging whether the area can be subjected to sound alarm according to the position information and a prestored alarm area plan, wherein the judgment basis can be the alarm area plan which is already stored in the alarm, and the prestored alarm area plan can be acquired from a cloud end or a server in a communication mode. If the area can be used for sound alarm, whether sound alarm can be carried out at the current time according to the pre-stored alarm time planning of the area is judged through a preset timer, then the alarm can obtain the current time through the built-in timer, it needs to be pointed out that the current time can be obtained through a network, then whether sound alarm can be carried out is judged according to the sound alarm time planning, and the alarm time planning can adopt the same obtaining mode as the area planning. And if the current time can be subjected to sound alarm, executing sound alarm. At this time, whether the vehicle or the pedestrian exists or not is judged whether the vehicle or the pedestrian exists in the region and time where the alarm can be given, and whether the alarm is given or not is executed according to the surrounding environment information.
In addition, it should be noted that the alarm-enabled area planning and the alarm-enabled time planning should be planning for alarm in advance for areas and time, and there is a sequence between the areas and the time planning, and the areas should be determined first, and then the time is determined.

turning off the alarm if the obstacle is not the vehicle or the pedestrian.
In this embodiment, a specific embodiment of the alarm is provided if the obstacle is not the vehicle or the pedestrian. When the obstacle is not the vehicle or the pedestrian, such as a building or other building, the alarm device cannot be turned off even if it is turned on, and therefore the obstacle cannot be avoided.
In an optional embodiment, after the step of determining whether the area can be subjected to the sound alarm according to the location information, the method further includes:
and if the area can not carry out sound alarm, executing alarm lamp alarm.
In this embodiment, a specific implementation manner is provided when the area where the alarm should be made to alarm if the obstacle is the vehicle or the pedestrian according to the previous determination, but the alarm is made by the warning lamp because the area where the alarm cannot be made to alarm by sound.
In an optional embodiment, after the step of determining whether the current time can be subjected to the audible alarm, the method includes:
and if the sound alarm can not be carried out, executing alarm lamp alarm.
In this embodiment, it is provided that when it is determined that the sound alarm cannot be performed at the current time, the warning light is executed to alarm. In this embodiment, the condition that the alarm can be sounded is still not met, and the area where the alarm is located may be in a time period or time when the alarm cannot be sounded, so that the alarm still alarms by using a warning light.
