The invention discloses a method for quickly judging whether the potential difference of the terminal button of an electric energy meter verification device is qualified. The steps of the invention are as follows: 1) For the electric energy meter verification device without access to a voltage transformer, each The standard value between terminals with the same name is J*? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? *U*1000(1); for the watt-hour meter verification device connected to the voltage transformer, the standard value between the same-named terminals of the tested watt-hour meter and the primary side of the voltage transformer is J**U*1000(2), and the standard watt-hour meter The standard value between the terminals with the same name on the secondary side of the voltage transformer is J**U*1000 (3), and the standard values ​​corresponding to different J values ​​are calculated according to formulas (1)~(3). Among them, the single-phase and three-phase electric energy meters When verifying the device, U is 220V and 57.5V respectively; Table 1~3 is obtained; 2) Measure the potential difference between the same-named terminals of the electric energy meter verification device, and compare the sum of the corresponding potential difference with the corresponding standard value in Table 1-3, if If it is less than or equal to the corresponding standard value in the table, the measured potential difference is qualified. The beneficial effect of the invention is that the on-site operation is simple and efficient, and helps to discover and solve problems in time.

The invention relates to a safety detection circuit and a detection method of a control button of a mine switch machine. The safety detection circuit includes a microprocessor, a frequency signal detection circuit, a level signal detection circuit and a mining button. In the frequency signal detection circuit, the input and output ends of the microprocessor are interactively connected with the input and output ends of the microprocessor, and the input and output ends are connected with mining buttons through mine cables. In the level signal detection circuit, its input and output ends are connected with mine buttons through a mine cable, and its output end is connected with the input end of a microprocessor. It can be seen from the above technical solutions that the present invention uses the frequency signal detection circuit and the level signal detection circuit to perform double safety detection on the mine button, which can effectively solve the false detection caused by the mine button shaking and contact adhesion. The safety detection of the control button of the mine transfer withdrawal machine is realized at a lower circuit cost.

The invention provides a terminal key processing method and device. The terminal is provided with an ink screen, and the method includes: when the terminal is in a dormant state, detecting the intensity of touch characteristics of at least one virtual key on the ink screen; wherein, the at least one virtual key is based on key layout information refreshed on the ink screen; when the intensity of the touch feature increases to a preset threshold, based on the key layout information, execute the operation instruction corresponding to the virtual key. The embodiment of the present invention realizes that after the terminal sleeps, the terminal is operated through the virtual keys displayed on the ink screen, and the operation is simple and the user experience is high.

The invention discloses a long-button function displaying method of mobile communication terminal, comprising: first step of sensing the user button input; second step for judging whether the inputted button in the first step having long-button function; third step of outputting the indicator displaying the long-button function to the picture based on the judging result in the second step if there is long-button function. The user is easy to confirm which button in the terminal button having long-button function. Moreover, the indicator indicates that the long-button function gradually decreases or increases based on a certain time so as to make the user know the operation state of the long-button function at any moment and provide an effect for easily using the long-button. The indicator comprises the popup window displaying long-button function help and the clock for displaying the residual time of the long-button function operation. When the button containing the long-button function in the function button of the mobile communication terminal is pressed down, it displays indicator.

The invention discloses a terminal control method, a terminal and a computer-readable storage medium. The terminal control method monitors the number of triggers of keys on the terminal within a preset time period, and then judges whether the number of triggers exceeds a preset threshold. If the preset number of times exceeds the threshold, the communication parameters of the terminal are controlled according to the preset rules to reduce the number of triggers, which solves the problem of interference with the terminal buttons when the antenna is working in the prior art, causing the terminal buttons to be triggered frequently, which affects the user's ability to control the terminal. Normal use, resulting in poor user experience. The present invention also discloses a terminal and a computer-readable storage medium. By implementing the above scheme, the interference to the keys of the terminal when the antenna works is reduced, the normal use of the terminal by the user is ensured, and the user experience satisfaction is greatly improved.
