Background technique

There are many wisdom blackboards on the market now, built-in control system, additional touch screen is, it can be achieved that electronic instruction function Can, for example demonstrated on the touchscreen by electronic pen, traditional blackboard is efficiently solved in this way passes through ash brought by chalk teaching Dirt problem, such as dust in chalk can bring hidden danger to people's health.But gradually increasing with customer demand, it is desirable to Have realization point to read and a record function, in this way can oneself repetition learning, promote learning quality by improving study enjoyment, slap More knowledge contents are held, but most of at present do not have this function.

Summary of the invention

It is an object of the invention to overcome the technical problem present on, it is black to provide a kind of family with communication function Plate.

To achieve the above object, the technical scheme is that in the following manner realizing:

A kind of band a little reads, family's blackboard of record function, including blackboard body, installs on the side frame of the blackboard body There are a read through model and re-reading module；Described read through model is stored in the audio file in blackboard, including communication for click play Unit, central control module, point read key, the first power module, point and read start key, relay and playing circuit；The communication unit Audio file of the input terminal of member to obtain data storage in blackboard body, output end are connected by the communication unit Central control module, the point are read key connection central control module, are read to starting point；The point reads start key and passes through the first electricity Source module connects central control module, to be turned on or off the working power of a read through model；The central control module drives Motor type relay realizes the practical operation to playing circuit, realizes and plays；The re-reading module is for recording current voice messaging And it realizes and repeats playing, including sound pick-up, sampled voice circuit, single-chip microcontroller, delay circuit, playback circuit, repeating key, start key And second power supply module；The input terminal of the sound pick-up is sent out to acquire voice messaging, output end by sampled voice circuit Give the single-chip microcontroller；The re-reading key connection single-chip microcontroller, it is re-reading to start；The single-chip microcontroller passes through the delay electricity Road connects the playback circuit, realizes re-reading broadcasting；The start key connects single-chip microcontroller by second power supply module, to open Or close the working power of re-reading module.

Further, the central control module uses LPC2119 chip.

Further, the single-chip microcontroller uses LPC2119 chip.

Further, the voltage of the first power module output is 5V or 3.V.

Further, the voltage of the second power supply module output is 5V or 3.V.

The present invention installation point read through model and re-reading module on side frame are realized to click to read at any time by read through model and be broadcast Playing function repeats playing function by re-reading module realization broadcasting content, greatly improves the learning quality of child.

Specific embodiment

The following describes the present invention in detail with reference to the accompanying drawings and embodiments.

As shown in Figure 1, a kind of band is a little read, family's blackboard of record function, including blackboard body 1, in the blackboard sheet Installation has a read through model 2 and re-reading module 3 on the side frame of body 1.

As shown in Fig. 2, described read through model 2 is stored in the audio file in blackboard, including communication unit for click play Member, central control module, point read key, the first power module, point and read start key, relay and playing circuit；The communication unit Audio file of the input terminal to obtain data storage in blackboard body, output end passes through in communication unit connection Control module is entreated, the point is read key connection central control module, read to starting point；The point reads start key and passes through the first power supply Module connects central control module, to be turned on or off the working power of a read through model；The central control module driving Relay realizes the practical operation to playing circuit, realizes and plays；

As shown in figure 3, the re-reading module 3 is used to record current voice messaging and realization repeats playing, including sound pick-up, sound Sound sample circuit, single-chip microcontroller, delay circuit, playback circuit, repeating key, start key and second power supply module；The sound pick-up Input terminal is sent to the single-chip microcontroller by sampled voice circuit to acquire voice messaging, output end；The repeating key connects The single-chip microcontroller is connect, it is re-reading to start；The single-chip microcontroller connects the playback circuit by the delay circuit, realizes re-reading It plays；The start key connects single-chip microcontroller by second power supply module, to be turned on or off the working power of re-reading module.

Preferably scheme, the central control module use LPC2119 chip.

Preferably scheme, the single-chip microcontroller use LPC2119 chip.
