Embodiment 1

[0025] An automatic control system for school bells, such as figure 1 Shown: It includes a bell module, a timing module, a control module and a supplementary module. The bell module includes multiple bell units distributed in different locations, such as the bell units located on different teaching buildings. The bell units can be used in existing For electric bell products, the timing module can be used for timing. The timing module can use the existing 24-hour timer, and the control module can obtain the time information of the timing module. The control module can use existing single-chip microcomputers, such as STM32 series or SOC single-chip microcomputers. The time information controls the ring module to perform sound prompts, for example, at 9:00, 9:45 and 9:55, the power to start the ring module, and the control module controls the ring module to perform sound prompts by powering on the ring module or sending The terminal sends voice information to proceed.

Embodiment 2

[0032] The difference with Embodiment 1 is that it also includes a display module, and the display module can use an existing LCD display screen, and the sound sensor for detecting the sound information when ringing is installed on the ringing unit, and the control module obtains the sound information of the sound sensor, controls The module compares the sound information with the preset sound to determine whether the ring unit is damaged. The sound information and the preset sound can be compared to determine whether the ring unit is damaged by volume or voiceprint. When the volume of the sound information is lower than the preset sound and reaches a certain volume When the values ​​are different or the voiceprint information is different, it is judged that the ring unit is damaged, and the preset sound is the sound when the ring unit is not damaged. When it is judged that the ring unit is damaged and the change information is obtained, the sound information is not the default ...

Embodiment 3

[0035] The difference with Embodiment 2 is that when the control module obtains the sound information, it counts to obtain the count value, the control module counts through the counting program, and the control module compares the count value with the prestored ring unit quantity value, when the count value is equal to value, the control module compares the sound information with the preset sound to determine whether the ringing unit is damaged or not when all the ringing units are ringing.

[0036] By counting when the sound information is received, the sound information and the preset sound are judged when the count value is equal to the number of rings, and the judgment is triggered when multiple rings ring at the same time to prevent failures caused by unactivated ringing units Interference or error in judgment.

Abstract

The invention relates to the technical field of electric bell control, in particular to an automatic control system of a school bell, which comprises a ringing module, a timing module and a control module, wherein the timing module performs timing, and the control module acquires time information of the timing module and controls the ringing module to perform voice prompt according to the time information. The system further comprises a supplementary module, the supplementary module receives the course information and the change information and sends the course information and the change information to the control module, the change information comprises the change frequency and change time of ringing, and the control module controls the ringing module to stop voice prompt according to the course information. And after the ringing module pauses the sound prompt, the control module controls the ringing module to perform sound change prompt according to the change times, the change time and the time information. According to the invention, the ringing module is automatically powered off according to course arrangement, which is more energy-saving.

Description

technical field [0001] The invention relates to the technical field of electric bell control, in particular to an automatic control system for school bells. Background technique [0002] The bell is a device that emits sound at regular intervals to remind the time point, and is generally used in schools to remind when class is on or after class. In order to carry out the prompting of sound on time in school or other places, bell bell generally uses electric bell, and electric bell regularly rings the bell and prompts. During the time period when there is no class, the ringing of the electric bell will cause environmental noise and waste resources. To solve this problem, it is generally avoided by directly cutting off the power. However, when the power is forgotten, it is still easy to cause waste of resources, and it may be necessary to reset the ringing time when restarting after a power failure, which will affect the use. Contents of the invention [0003] The present ...
