Description

[0002] The digital displays currently on the market have their programs hard-coded before leaving the factory, and users cannot remotely set them according to their needs, especially digital displays used for micro-teaching. When students conduct skill training in a micro-teaching laboratory, they need to train a certain skill within a specified time. Generally, micro-teaching laboratories do not have clocks, and even if they are, they only have the single function of displaying the current time. Therefore, during the training process, students cannot intuitively obtain the remaining training time, and can only constantly estimate the remaining training time by themselves, which makes it impossible for students to devote all their energy to skill training, resulting in students being unable to train within the effective time, reducing the effect of skill training.

[0118] See also Figure 5 The present invention also provides a timing display method of a remote-controlled digital timing display device for microteaching, comprising the following steps:

[0119] Step S1, the single-chip main controller of the main control circuit, its infrared signal receiver and Bluetooth signal receiver are always in the signal receiving state, and the following three detection steps are performed in real time:

[0120] (1) The single-chip microcomputer main controller detects the Beidou satellite signal in real time through the Beidou signal receiver and executes step S2;

[0121] (2) The single-chip main controller detects in real time whether there is an infrared signal through an infrared signal receiver. If there is an infrared signal, step S2 is executed; if not, infrared signal detection is performed in a loop;

[0122] (2) The single-chip main controller detects in real time whether there is a Bluetooth signal through a Bluetooth signal receiver. If there is a Bluetooth signal, step S2 is executed; if not, Bluetooth signal detection is performed cyclically;

[0123] Step S2, the single-chip main controller determines in real time whether an infrared signal and / or a Bluetooth signal is detected, if yes, then execute step S3; if no, then execute step S4;

[0124] Step S3, making the LED display screen enter the remote control mode, at this time, the single chip main controller encodes and analyzes the infrared signal and / or Bluetooth signal, obtains the input and control signal from the input remote control, and drives the LED display screen to display the relevant information from the input remote control in the designated area through the LED driving module;

[0125] See also Figure 6 , step S3 is specifically as follows:

[0126] After the single-chip main controller detects the infrared signal and / or the Bluetooth signal, it decodes the infrared signal and / or the Bluetooth signal, translates it into a recognizable code, and performs code analysis to determine the function corresponding to the signal. The specific method is as follows:

[0127] Step S3.1, after detecting the switch signal, determine whether an ascending timing display mode signal or a descending timing display mode signal is detected. If not detected, continue to detect in a loop; if detected, execute step S3.2;

[0128] Step S3.2, if it is an ascending timing display mode signal, then the timing ascending and descending sequence flag is set to TRUE; if it is a descending timing display mode signal, then the timing ascending and descending sequence flag is set to FALSE;

[0129] Step S3.3, determine whether the timing time mode signal is detected, if not detected, then loop and continue to detect; if detected, execute step S3.4;

[0130] Step S3.4, determining whether the type of the timing time mode signal is a custom timing time mode signal, if yes, executing step S3.5; if no, executing step S3.6;

[0131] Step S3.5, enter the custom timing time mode, monitor the function buttons, obtain the cursor movement direction according to the monitored function buttons being pressed, and thus obtain the custom timing time; then execute step S3.7;

[0132] Step S3.6, enter fixed timing mode:

[0133] Decode and analyze the received signal to determine the currently pressed fixed timing mode button, thereby obtaining the bound designated timing time; then execute step S3.7;

[0134] Step S3.7, encoding the custom timing time or the specified timing time and sending it to the LED driving module, driving the LED display screen to start displaying the timing time in the main display area and performing timing;

[0135] Step S3.8, when the LED display screen is timing, the main control circuit determines in real time whether a reset signal and a clear signal are detected; if not, the detection is continued in a loop; if detected, step S3.9 is executed;

[0136] Step S3.9, if a reset signal is detected, the current timing time is reset to the beginning of the timing time selected or set by the user, and then the count is reduced by one every second;

[0137] If the reset signal is detected, the current timing time is reset to zero and then the count is increased every second.

[0138] Step S4, making the LED display screen enter the time display mode, the single-chip microcomputer main controller processes and encodes the Beidou satellite signal, obtains the current time, and drives the LED display screen to display the current time in the designated area through the LED driving module.

[0139] The following is an embodiment of a timing display method of a remote control digital timing display device for micro-teaching:

[0140] (1) The infrared signal receiver and Bluetooth signal receiver are always in the signal receiving state, and the Beidou signal receiver receives Beidou satellite signals in real time. The received infrared signal, Bluetooth signal and Beidou satellite signal are used as inputs of the microcontroller main controller. Beidou satellite signals are used for time synchronization of the timer, and infrared and Bluetooth signals are used for notification of the timer.

[0141] (2) When in time display mode, the microcontroller receives the Beidou satellite signal, processes and encodes the Beidou satellite signal, and inputs it to the LED driver module to display the current time.

[0142] (3) The user clicks the switch button to enter the time setting mode. After detecting the infrared or Bluetooth signal, the microcontroller decodes the signal, translates it into a recognizable code, and performs code analysis to determine the function corresponding to the signal:

[0143] 1. Determine whether the timing is ascending or descending. If ascending timing is selected, set the timing ascending and descending flag to TRUE; if descending timing is selected, set the timing ascending and descending flag to FALSE.

[0144] 2. Determine the time setting signal. If it is a fixed timing time mode signal, decode and analyze the received signal according to the detection, and determine whether it is T1, T2, T3, or T4. Then send the corresponding time value code to the LED driver module for display. If it is a custom timing time mode signal, the user can press U3 or U4 to move the cursor left or right to select the time position that needs to be set, that is, two digits for minutes and two digits for seconds. The user can press U1 or U2 to select the position currently selected by the cursor. After the selection is completed, press the confirmation button, and the microcontroller will send the current input time code to the LED driver module, which will be displayed on the LED display and start timing.

[0145] 3. If the user needs to reset or clear the current time during the timing time, he can press the reset button or the clear button. After detecting the reset signal, the microcontroller main controller resets the current time to the time selected or set by the user, and then decreases the count every second; after detecting the clear signal, the microcontroller main controller clears the current time and then increases the count every second.
