Detailed ways

The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. the

As shown in Figure 1, the present invention designs a remote pet feeder based on GPRS, including a food storage barrel and a food bowl, wherein the bottom of the food storage barrel is provided with a sliding door, and the sliding door of the food storage barrel is connected to a sliding door. Road, the food storage barrel is connected with the food bowl through a slideway, and also includes a power supply, a GPRS module, a single-chip microcomputer, a motor drive chip, and a stepping motor arranged on the food storage barrel, wherein the power supply is used to provide power; The GPRS module is connected with the single-chip microcomputer, the motor driver chip, and the stepper motor in turn; the stepper motor is connected with the sliding door of the food storage barrel; the external communication device is used to send information to the GPRS module through the GPRS network, and the GPRS module transmits the information after receiving the information to the single-chip microcomputer for analysis; the single-chip microcomputer transmits control signals to the motor drive chip, and the motor drive chip generates a drive signal to drive the stepping motor to rotate; the rotation of the stepping motor drives the opening or closing of the food storage bucket sliding door. the

In addition, a timer and a display screen arranged on the food storage barrel are added, and the timer and the display screen are connected to the single-chip microcomputer respectively, so that the user can set the time through the timer when it is inconvenient to send control messages. In order to better simulate the on-site scene of the owner, voice recording and playback can be performed through the recording module and the player. The recording module is connected to the timer, and the player is connected to the single-chip microcomputer. Further, in order to let the owner know the pet’s eating time and frequency, the infrared sensor can be set on the food bowl to obtain the sensing signal, the infrared sensor and the camera are connected to the single-chip microcomputer respectively, and the camera is controlled by the single-chip microcomputer to take pictures of the pet’s eating and store and record the time . The food bowl is provided with an LED light, and the LED light is connected with a single chip microcomputer for illuminating the food bowl. the

The specific working process of the present invention is as follows: first, the user adds enough pet food to the food storage bucket through the lid on the food storage bucket before going out, and turns on the power switch. During going out, the user can send a short message to the GPRS module through an external communication device such as a mobile phone through the GPRS network. The card number corresponding to the SIM card is installed in the GPRS module. Start to feed the pet, "1" indicates the quantity level of the pet food fed. After receiving the short message, the GPRS module sends the content of the short message to the microcontroller through the serial port. After the single-chip microcomputer receives the short message, it analyzes the content of the short message. After the analysis is completed, a signal is sent to the motor drive chip, and the motor drive chip generates a drive signal to drive the forward and reverse rotation and stop of the stepping motor. The door is opened, and the opening time of the storage barrel sliding door is controlled according to the level of pet food fed in the text message. During this time, the pet food in the food storage barrel passes through the slide from the exit and falls into the food bowl. After a certain period of time, The sliding door is closed. In order to let the owner know the eating time and times of the pet, the infrared sensor can be set on the food bowl to obtain the induction signal, and the camera can be controlled by the single-chip microcomputer to take pictures of the pet eating and store and record the time. time to see how your pet is eating. the

In addition, a timer and a display screen are added. When the user is not at home and it is inconvenient to send control messages, the time can be set on the timer before going out and displayed on the display screen. For example, the eating time of 3 meals a day can be set. When the time reaches the set time, the single-chip microcomputer sends a signal to the motor drive chip, and the motor drive chip controls the forward and reverse rotation and stop of the stepping motor, so that when the time arrives, the sliding door is opened for a certain period of time, and the food can automatically slide down from the slide to the food tray. pot. Among them, before going out, the user can record the sound through the recording module and store it in advance. When the timer time arrives, the single-chip microcomputer calls the stored recording and decodes and plays it through the player, so as to create a real presence when the pet is eating. It is convenient for pets to find the food bowl and eat in time. the

When the light is insufficient, the food bowl can be illuminated by LED lights, which is convenient for pets to find food. And the GPRS module adopts MC35i of Siemens, which is connected with the single-chip microcomputer through the serial port, which makes the communication more stable. The motor drive chip is Toshiba's TA7267BP drive chip, which can better realize the drive function and generate stable drive signals. The single-chip microcomputer adopts MCS-51 series, which can make the corresponding speed faster. the

Therefore, the present invention enables the feeder to provide pet food on time and in a timely manner through the remote control of the owner, so that the pet eats on time and the owner feeds on time, avoiding irregular eating of the pet, and facilitating remote control. It can control the times and food intake of pets at any time, avoid the embarrassment of no one feeding pets when no one is at home, satisfy people's pet feeding problems when they go out, and can be well provided to users. the
