The invention discloses a parking lot entrance / exit control method and a parking lot entrance / exit control system based on Bluetooth. Beacon devices, which are respectively disposed on an entrance gate and an exit gate of a parking lot, are used as broadcasting devices to transmit broadcasting information in iBeacon form based on the Bluetooth 4.0 technology. A Bluetooth mobile terminal disposed in a vehicle is used to receive the Bluetooth broadcasting information, and is used to calculate the distance between the vehicle and a gate rod, and when the vehicle is close to the gate rod, the Bluetooth mobile terminal disposed in the vehicle is used to establish a BLE connection with a Bluetooth connecting device disposed on the gate for data exchange. An industrial control host is used to determine whether the gate rod can be lifted by combing with a Bluetooth connecting signal, a ground sensing signal, a microwave sensing signal, and other signals, and is used to calculate a number of residual parking stalls, and then the result is output and displayed by a display screen. The users can enter and leave the parking lot quickly without stopping the vehicle by using the Bluetooth function of the mobile terminal, and therefore the passing rate of the vehicle is effectively improved, the identification precision is high, and the intelligent parking functions such as identity authentication, parking fee calculation, and electronic payment, and so on are effectively supported by adopting the anti-counterfeiting and encrypted Bluetooth data exchange function.

The invention discloses a functional block function modeling method for visual programming, which includes: the first step, defining text segments of the functional block function as seven key fields including information description, header file content, parameters, member variables, a code structuring segment, a code initializing segment and a function body code segment, wherein a header file comprises information and variable definition; the second step, analyzing a functional block defining text, extracting segment content corresponding to the key fields, extracting formal parameters of function to form input points of graphs; utilizing a returned value as a first input point in a default manner; analyzing definition statements of the member variables to form an output variable table and output the same; and the third step, processing extensional conditional-compilation statements during code generation, and outputting branch codes corresponding to the conditions. The member variables in the functional block function modeling method are flexible in definition, easy to transplant, visual and understandable, and are convenient for users to develop and maintain.

The invention discloses a method, device and wireless acceleration system for processing interactive data, relates to the field of communication technologies, and solves the technical problems of relatively poor interactive data processing capacity and slow response between the mobile network and the Internet in the prior art. The method comprises the following steps: a core switch forwards user requests sent by a wireless packet gateway to the wireless acceleration system according to strategy routing of pre-set uplink data; the wireless acceleration system determines whether a corresponding response data duplicate is cached locally according to web sites in the user requests; if the situation that no corresponding response data duplicate is cached locally is determined, response data returned by request websites is acquired through the request websites, wherein the user requests are sent to the Internet through the request websites; the wireless acceleration system conducts acceleration processing on the response data, and then sends the accelerated response data to clients corresponding to the user requests. The method, the device and the wireless accelerate system are mainly used for data access processing of the mobile network.
