Description

Technical Field

[0001] The invention relates to the technical field of wireless communications, in particular to a mobile alarm receiver. Background Art

[0002] The alarm receiver is used to obtain various alarm and monitoring data, receive, process and analyze various alarm data, and send out alarm signals as needed, ultimately realizing early warning and response to potential dangers. It has the function of receiving various popular alarm communication formats and is compatible with most alarm controllers on the market. After receiving the alarm information, it transmits the alarm information to the alarm receiving platform, which will immediately receive the alarm and take action.

[0003] When the police inspection vehicle is on patrol, if the command center receives a police situation, it is generally redistributed through the command center, and there is a certain lag in the analysis of police force. The initial notified personnel cannot always maintain sufficient mobility and need to be redeployed. Under the condition of tight police force, such redeployment will further delay the police situation. If the police inspection vehicle is directly equipped with an alarm receiver, it can receive and broadcast the police situation and directly participate in the handling of police incidents outdoors. Traditional alarm receiving systems often rely on equipment in fixed locations, resulting in a slow response speed when handling emergencies. Insufficient signal coverage in some areas makes it difficult to achieve comprehensive monitoring. The alarm and environmental data of the existing system often cannot be collected and analyzed in real time, resulting in the inability to quickly obtain and process information when an incident occurs. There are difficulties in integrating different data sources, resulting in incomplete grasp of real-time information.

[0004] Current patrol or response paths are often static and difficult to adjust in advance by predicting future situations. Many existing systems can only process historical event data and lack future prediction capabilities based on big data analysis. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a portable alarm receiver, which can effectively solve the problems of the prior art.

[0007] (II) Technical solution

[0027] Furthermore, the prediction model calculates the alarm change trend in a preset future time period using the following formula:

[0028]

[0029] In the formula, P(t+Q) represents the prediction result of the alarm change trend in the future period, Q represents the preset future time period, a represents the adjustment factor of the prediction model, F(t) represents the alarm event frequency, D(t) represents the alarm quantity change trend, and represents the change rate of the alarm event in unit time. j (t) represents the number of alarm events of a specific event type j occurring at time t, T j represents the average processing time of different event types j, R maxrepresents the maximum number of processing resources allowed by the system, R(t) represents the number of processing resources available at time t, S(t) represents the change history of the alarm event processing status, W(t) represents the weather status at time t, and C(t) represents the traffic status at time t.

[0030] Furthermore, the specific logic of the path adjustment module to adjust the mobile path is: give priority to areas with low processing completion and areas where new alarm events are located, use traffic conditions and weather data as reference items, compare the current location with the default path, and calculate and output the optimal route adjustment plan based on preset indicators.

[0057] Example 2

[0058] At other levels, this embodiment also provides a method for constructing and expressing a prediction model.

[0064] When the present invention is in the mounted state, the mounted vehicle can quickly arrive at the scene of the incident, thereby improving the response efficiency. By setting the alarm radiation range and moving within this range, the coverage effect of each area can be improved. By collecting data in real time and performing preliminary classification and cleaning, key information can be extracted more quickly to support quick decision-making. The path can be dynamically adjusted according to the alarm information and the current processing progress, and it can adapt to changing needs more flexibly. By integrating multiple data sources, information can be acquired and integrated more effectively. By building a prediction model and analyzing historical data, areas that need priority processing can be better identified, and prevention capabilities can be improved. A collection authority security authentication mechanism is introduced to ensure the security of data reading and downloading.

Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
