The invention discloses an urban road parking management method and a system thereof. The method of the present invention comprises the following steps: S1, real-time dynamic acquisition of the entry and exit state information of vehicles at each road parking lot crossing; S2, judging whether the vehicle has a parking behavior according to the stagnant state of the entry vehicle; S3, calculating the parking behavior. The parking time of the exiting vehicle is deducted from the payment instrument bound to the exiting vehicle according to the parking time. The system of the present invention corresponds to the method described above. The present invention can centrally and effectively manage and solve the problem of parking on urban roads. Compared with traditional geomagnetism and parking space detection devices, the present invention only needs to assume a camera at each intersection, which greatly saves costs; after obtaining user authorization for the first time , can realize automatic deduction, and can record the deduction of parking section and time in detail, which is very convenient.

The invention discloses a control method of a frequency-selective electromagnetic radiation monitor and relates to the technical field of electromagnetic radiation detection. The present invention includes a range selection step and a noise floor subtraction step. In the range selection step, the main controller acquires the electromagnetic radiation signal at regular intervals and calculates the maximum strength of the current signal, compares it with the end value of the current range gear range, and performs an upgrade according to the comparison result. The operation of shifting, downshifting judgment and maintaining the gear position; the downshifting judgment operation is to determine the duration of the maximum signal strength less than the minimum value of the current range gear, and if the duration reaches the configured time, the downshifting operation will be performed. The invention adopts the mechanism of steep rise and slow fall to automatically adjust the range gear, which can avoid the situation of repeated change of the range gear due to the fluctuation and change of the electromagnetic radiation signal. The invention can eliminate the influence of background noise on the measured value, so that the frequency-selective spectrum analyzer can accurately measure the electric field intensity of the current environment no matter under any conditions.

The invention provides a railway construction organization plan automatic arrangement method and system and a storage medium, and the method comprises the steps: building or importing construction organization plan information, the construction organization plan information comprises a plurality of operation types contained in a current construction project, and the grading operation item nodes contained in each operation type; determining a front node of each hierarchical operation item based on the operation item logic relation information between the hierarchical operation item nodes; determining the operation speed of each operation type based on the corresponding relationship between each operation type and the construction speed influence factor; performing forward and reverse arrangement based on the construction period starting time, the operation speed and the time constraint of the front node of each graded operation item, respectively generating the first starting time, the end time, the second starting time and the end time of each operation item, and determining key operations in each graded operation item and a key path formed by the key operations; and generating an automatic laying result of the railway construction organization plan based on the key operation and the key path formed by the key operation.

The invention relates to a control terminal, embedded main board and parking system and method. The control system comprises a microprocessor and a radio frequency receiver which is connected with the microprocessor in a communication mode and / or an image acquisition device for obtaining a radio frequency signal or an image, the control system further comprises a communication unit which is connected with the microprocessor in a communication mode, the communication unit sends the radio frequency signal and the image obtained by the radio frequency receiver and / or the image acquisition device to an embedded main board which is connected with the radio frequency receiver and / or the image acquisition device, a signal conversion circuit in the embedded board analyzes the radio frequency signal and the image to obtain the corresponding license plate number information and time information, a communication circuit sends the obtained license plate number information and the time information to a default server to facilitate a server to deduct on the parking fee according to the obtained license plate number information and the obtaining time of the license plate number information, so that automatic deducting of the vehicle parking fee is achieved, and parking charging cost is saved and parking charging efficiency is improved.
