The invention provides a control system of an electric bicycle.The control system comprises a controller, a central control lock and a wireless communication module which are connected with the controller, and the central control lock is used for locking a motor; the wireless communication module is used for enabling the controller to be connected into an internet in a wireless communication manner; the controller is used for acquiring a command by the internet and opening and closing the central control lock and a whole vehicle power switch according to the command.According to the control system and a control method of the electric bicycle, no key control is adopted, the whole electric bicycle can be controlled by a mobile terminal carried along, and the inconvenience of carrying a lot of keys is avoided; at the same time, when the electric bicycle is ridden, information of the position, the speed, the battery level and the like of the electric bicycle can be known in real time, the state of the whole electric bicycle is mastered, the electric bicycle use safety is improved, the position of the electric bicycle can be mastered in real time, and the electric bicycle can be found in the first time when stolen.

According to one aspect of the present invention, a marine floating dock carrying precision management system is provided, which can continuously monitor the floating dock with a strict inner wall reference in order to manufacture structures on the marine floating dock and perform precision management, and can monitor the internal hull block for efficient precision management. To this end, the marine floating dock carrying accuracy management system according to an embodiment of the present invention includes: a monitoring unit, which includes a profile sensor arranged in the dock and detecting the curvature of the bottom surface of the dock and a sensor arranged outside the dock and detecting the state of the side wall of the dock The photography department; the measurement department, which is installed in the dock and measures the status of the hull blocks mounted in the dock in real time; the deployment accuracy management department, which is installed inside the dock, and changes the accuracy of the dock according to the effect of the hull blocks mounted in the dock Manage; control part, it comprises coordinate conversion part and analysis part, controls carrying precision management part according to the result of analysis part, manages the precision of dock, and described coordinate conversion part will be converted into A reference coordinate, and the analysis unit analyzes the status of the dock and the status of loading accuracy based on the converted information. Thereby, the floating dock can be continuously monitored and the accuracy of the hull blocks inside the dock can be managed based on the strict inner wall reference of the dock, so that the status of the floating dock can be grasped more accurately, and the ballasting of the dock can be performed more accurately.

The invention discloses a method and system for restricting the ECG (Electrocardiogram) interference caused by cardio-pulmonary resuscitation and an external defibrillator, relating to the technical field of EGG detection. The method comprises the following steps: 1, acquiring an ECG signal and a voltage signal of a reference signal; 2, processing and analyzing the acquired ECG signal and voltage signal; 3, comparing the processed signals with a set value; 4, when the processed signal is greater than the set value, carrying out adaptive filtering; 5, when the processed signal is less than the set value, carrying out rhythm analysis; 6, processing and analyzing the signal subjected to adaptive filtering and returning to continuously execute the step 3. The method and system and the external defibrillator disclosed by the invention, the acquired ECG signal and the reference signal subjected to frequency domain analysis, and the energy of inference in the ECG signal and the proportion to the interference energy to the total energy of signals are calculated. The frequency of circulation filtering and the step length factor of adaptive filtering are controlled by using the proportion of the interference energy so as to realize dynamic adjustment of the filtering strength, the pushing interference element in the ECG signal is furthest restricted and the characteristics of the ECG signal are highlighted.

The invention discloses a device and a method for detecting and evaluating the contact network state based on electrical capacity analysis and relates to a method for detecting and evaluating the electrified railway contact network state. The technical scheme adopted by the invention is as follows: the method comprises the following steps: acquiring voltage and current signals: converting the voltage and the current of the contact network to obtain a signal by an optical electronic transformer, converting the obtained signal into an electrical signal by a photoelectric detector, feeding the electrical signal into a signal conditioning circuit and carrying out amplification, filtering, A / D (Analogue / Digital) conversion, isolation and digital sampling on the electrical signal; processing the voltage and current signals: extracting a high-frequency component of the voltage and current signals, which is obtained by sampling, and carrying out computing processing on the high-frequency component; and estimating the contact network: according to the calculation result, evaluating the work state of the contact network and giving out an evaluation result. According to the method and the device disclosed by the invention, the detecting and evaluating result is accurate, the state of the contact network can be better grasped and the state overhaul of the contact network is facilitated to be realized.
