Magnetoresistive sensor and ZigBee network-based intelligent method for monitoring vehicle flow

The invention relates to a intelligent method for monitoring vehicle flow, wherein the method is based on a magnetoresistive sensor and a ZigBee network. The method is used to solve some problems in urban traffic. According to the invention, vehicle flow in traffic is monitored. And then after data is processed, the data is transmitted to a traffic control department and a communication service provider; on one hand, the obtain data information is further utilized by the traffic control department to lead and control the traffic; on the other hand, the communication service provider utilizes a self-communication network to give guidance to information-demanding users including mobile communication users for their trips. Therefore, people can understand the situation of the amount of the traffic without passing a section of a road; consequently, support is provided for selection of trip routes of the people taking trips, so that it is convenient for the people to go out and an operation of a city becomes more efficient. With utilization of the mobile communication network of the communication service provider and mobile terminal equipment like a mobile phone and a PDA and the like, traffic indication and guidance are provided for people that go out and people that are on the way, so that a traffic jam degree can be reduced, traffic accidents can be avoided, and success rates of handling special events like emergency rescue and disaster rescue can be improved.

Method for automatically screening abnormal electricity consumption user

The invention belongs to the technical field of intelligent electric energy meters and provides a method for automatically screening an abnormal electricity consumption user. The method comprises the following steps of calculating line loss; acquiring a focus distribution area according to the line loss, wherein the focus distribution area is a distribution area of which the line loss is greater than a set threshold value; processing current electricity consumption data and historic electricity consumption data of users in the focus distribution area to obtain suspected electricity larceny users. User data are classified through normal distribution and are respectively calculated according to the classified users, and the suspected electricity larceny users can be quickly and accurately found according to special event factors, holiday factors, seasonal factors and the like. According to the method, by mining electricity consumption data, the abnormal electricity consumption user can be timely found, electricity consumption disputes are reduced, an electricity larceny behavior is effectively found, and a normal electricity consumption order is maintained. Parameters such as user classification coefficients and the seasonal factors can be finely adjusted according to an actual operating effect after user classification and calculation are completed in a calculation process so as to achieve an accurate analysis effect.
