Embodiment
As shown in Figure 1, the electronic watch of classroom or teacher's special use comprises clock and watch shell, clock face, movement and telepilot, and the annexation of movement inside is: control chip respectively with display driver chip, clock chip, infrared remote receiver, data-carrier store, button, stroke generator, temperature and humidity sensor be set be connected; Display driver chip is connected with LED nixie display or LCD LCD.
Shown in Fig. 2,3,4, what day, which class, when described clock face shows, last class hour, shows that clock face when changed the countdown that shows the class period into.Clock and watch shell and telepilot are provided with button are set: navigation button, increase button, minimizing button and ACK button.
The utility model course of work
1) utilize " navigation button ", " increase button ", " minimizing button " and " ACK button " (as shown in Figure 3) on clock and watch shell and the telepilot school's schedule of classes and times (as shown in table 1) to be input in the storer of electronic watch of classroom or teacher's special use, the electronic watch of classroom or teacher's special use will be according to school's schedule of classes and times operation;
When 2) having no class, i.e. time break, what day the electronic watch of classroom or teacher's special use can show, get off with last which class and current when be;
3) at school the time, what day the electronic watch of classroom or teacher's special use can show, be which class now.And show that charactron when will change the countdown that shows duration of a period (for example 45 minutes) into, promptly show how long finish class in addition.Also can show reverse countdown, promptly how long pass through till now on class from beginning.This makes things convenient for the teacher to grasp teaching process on class;
4) show temperature and humidity that charactron when can the current classroom of Alternation Display or which date;
5) ring bell for class, after class bell and preparation bell (respectively ringing the preparation bell in 10 minutes in advance in the morning, afternoon and evening) on time.
Table 1 is that schedule of classes and times is given an example.
Table 1, schedule of classes and times are for example
Electronic University Of Science ﹠ Technology Of Hangzhou's schedule of classes and times
Using method of the present utility model
At first the schedule of classes and times with school is input in the electronic watch, so that electronic watch is by the schedule of classes and times operation of input.For the convenience of narrating, we press the charactron on the display board from top to bottom, serial number from left to right.Input method is as follows:
1) utilization is provided with the button input: according to the schedule of classes and times shown in the table 1 (the preparation bell is by routine processes) first class is that 8:55 begins, and 9:40 finishes.In order to import this information, press " navigation button ", No. 2 charactrons flash on the display board, at this moment press " increase button ", the numeral of demonstration increases, and presses " minimizing button ", the numeral that shows reduces, we press " navigation button " when the numeral that shows is 0, and at this moment, 0 of No. 2 charactron demonstrations will be noted, No. 3 charactrons will flash simultaneously, we press " increase button ", and the numeral of its demonstration is increased, or press " minimizing button ", the numeral of its demonstration is reduced, we press " navigation button " when the numeral of No. 3 charactron demonstrations is 1, and 1 of No. 3 charactrons demonstrations this moment will be noted, and No. 4 charactrons will flash simultaneously.Like this, display board has shown that (first place is 0 to the 01st joint, then do not show), because No. 4 charactrons flash, we can utilize " increase button " and " minimizing button " to be provided with No. 4, No. 5, No. 6 and No. 7 charactrons show 08:55, press " navigation button " again No. 4 charactrons are flashed, process makes No. 4, No. 5, No. 6 and No. 7 charactrons demonstration 09:40 above repeating.The beginning and ending time of first class has just been imported well like this, and same mode can all be imported into the beginning and ending time of second joint, the 3rd joint or the like.After all input finishes, press " ACK button ", input is finished, and the electronic watch of classroom or teacher's special use will be according to the schedule of classes and times running of input.
2) utilize the remote controller buttons input: it is basic identical that input method and utilization are provided with the button input.Notice that the button in the middle of the telepilot is an ACK button, the upper and lower button of telepilot is respectively to be increased button and reduces button, and the button on telepilot the right is a navigation button, and the button on the telepilot left side also is a navigation button, can make position (flashing the position) is set moves to left.
The schedule of classes and times input finishes, and presses " ACK button ", and the electronic watch of classroom or teacher's special use will enter normal display state.After pressing " navigation button " once more, enter schedule of classes and times input or modification state.
Fig. 5 has provided the integrated circuit (IC) chip that each element circuit adopts, and can select functionally similar other types chip when specifically making for use.In order to reduce the thickness of finished product profile, this circuit adopts the resistance-capacitance depressurization power circuit, as shown in Figure 5.Wherein R1 and C1 realize ac buck, and U1 is full-wave rectification, and C2, R3 and DW1 realize filtering and voltage stabilizing.Input 220V is output as 5V.Notice that clock chip and data-carrier store adopt the point protection chip, having a power failure not to cause the error of loss of data or clock, will normally show behind the incoming call.
Fig. 6 has provided the program flow diagram of control chip, and after the system reset, control chip is time for reading information from clock chip, with schedule of classes and times in the storer relatively after, determine present content displayed: what day, which class, whether demonstration time or countdown need belling.When pressing signal, system enters the state of setting as " navigation button ", enters normal operating conditions again after the schedule of classes and times input finishes, if the state that is provided with does not have input signal for a long time, system enters normal operating conditions automatically.
