Description

Technical Field

[0001] The utility model relates to the technical field of driving control, in particular to a driving controller, a control box and a control system. Background Art

[0002] With the rise of large-scale and intensive farming and the development of intelligent farming equipment, the overall feeding system has become more intelligent than before. The original relay circuit is more difficult to implement, and the complex system is more prone to failure, making subsequent maintenance more difficult and not conducive to connecting the feeding to the Internet of Things in the future.

[0003] In the poultry farming process, the crane is generally located at the front end of the chicken house and is mainly controlled by the main control box or the crane control box. The main process is that the crane receives the feed from the main feed line at the front end and evenly spreads it into the cage trough.

[0004] With the advancement of intelligent farming equipment, there is a growing demand for more refined feeding control. However, existing feeder cranes within chicken houses only offer daily timed control, lacking precision and functionality, making them difficult to meet the demands of intelligent farming equipment. Furthermore, traditional relay-controlled feeder cranes occupy a significant amount of space within the control box, increase wiring complexity, and complicate future maintenance. Utility Model Content

[0009] The current detection module includes a plurality of current transformer groups, which are used to detect the current of the corresponding driving motor and feed it back to the main control MCU;

[0010] A digital quantity isolation input module is used to transmit external input digital quantity information to the main control MCU through an optical coupler;

[0011] A driving control output module includes a plurality of first relays, each of which is controlled by the main control MCU, and an output end of each first relay is connected to a contactor corresponding to the driving motor to control the rotation of the corresponding driving motor;

[0012] The alarm output module includes a second relay, which is controlled by the main control MCU, and an output end of the second relay is connected to an external alarm device.

[0013] The beneficial effects of the above embodiment are: the crane controller is installed in the crane control box in the chicken house, and all the control circuits that originally needed to be composed of relays and motor protectors are integrated into the control board, which effectively reduces the wiring difficulty in the crane control box and reduces the device cost; the controller can have multiple functions through external sensors, realize accurate and flexible control of the crane, perform refined feeding, help breeders manage the feeding of chickens, and meet the needs of intelligent breeding equipment.

In addition, based on the slip detection information, that is, the pulse signal obtained for each rotation of the driven wheel, the number of rotations of the driven wheel is calculated, thereby calculating the forward and backward running distance of the driving wheel, and cooperating with the control of the driving control output module to achieve control of the driving position with limited precision.

The control panel is mounted within the housing, and a protective plate is provided on the front of the housing. The housing is mounted within the driving control box.

[0027] The embodiments of the present application solve the problems of insufficient control accuracy and lack of functionality of the crane in the prior art by providing a crane controller, control box and control system, thereby achieving precise and flexible control of the crane and meeting the needs of intelligent breeding equipment.

[0028] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:

[0029] Example 1:

[0030] like Figure 1 As shown, a driving controller includes a control board, which includes: a main control MCU and a power module connected to the main control MCU, a digital isolation input module, a driving control output module, a current detection module, an alarm output module, a communication module, and an address dip switch.

[0031] The power module is used to convert external power and supply power to the main control MCU; in this embodiment, it is used to convert 24V power input into 5V or 3.3V input.

[0032] The digital isolation input module is used to isolate the external digital information through optocouplers and transmit it to the main control MCU, thus achieving the separation of strong and weak electricity.

[0033] The crane control output module includes several first relays, which are controlled by the main control MCU. The output end of each first relay is connected to the contactor of the corresponding crane motor to control the rotation of the corresponding crane motor. This crane control output module can control multiple crane motors at the same time, that is, it can control the movement of multiple cranes. In this embodiment, it controls the movement of two cranes.

[0034] The current detection module includes several current transformer groups. The current transformers are used to detect the current of the corresponding driving motor and feed it back to the main control MCU.

[0035] The alarm output module includes a second relay, which is controlled by the main control MCU, and the output end of the second relay is connected to the external alarm device. In this embodiment, when the current information detected by the current transformer is abnormal, the motor is stopped and an alarm is sounded through the alarm output module.

[0036] The communication module is used to realize the communication between the main MCU and the external devices. The controller can be connected to the touch screen or environmental controller via 485 communication, which is convenient for subsequent centralized control and IoT control.

[0037] The address dip switch is used to set the address code during the communication process. When multiple controllers work together, different address codes need to be set during the communication process. The dip switch is used to set the communication address of each controller.

[0038] Furthermore, digital information includes vehicle limit information, button input information, and slip detection information. The vehicle limit information is sent by the limiters installed at both ends of the vehicle track to prevent overshoot. The vehicle is driven by an electric motor fixed to one end of the cage. The slip detection information is sent by a capacitive proximity sensor on the driven wheel fixed to the other end of the cage. Each time the driven wheel rotates, a pulse signal is received. When the vehicle slips, the driven wheel stops rotating. If no pulse signal is received for a certain period of time, the controller assumes that the vehicle has slipped or derailed, issues an alarm, and stops the motor. Furthermore, based on the slip detection information, i.e., the pulse signal received each time the driven wheel rotates, the number of rotations of the driven wheel is calculated, thereby calculating the forward and backward distance traveled by the vehicle. This is coordinated with the control of the vehicle control output module to achieve control of the vehicle's operating position with limited precision.

[0039] Furthermore, the driving controller also includes a housing and a protective plate. The control panel is installed in the housing. The protective plate is provided on the front of the housing. The housing is installed in the driving control box. The main control panel is protected to ensure the safety of equipment and personnel and prevent misoperation.

[0040] Example 2:

[0041] like Figure 1As shown, a driving control box has the driving controller shown in Example 1 built in. The driving control box is also provided with a main circuit breaker, a control circuit breaker, a 24V power supply, a plurality of contactors and an alarm light. The input end of the main circuit breaker is connected to the external power supply, and the output end is divided into two paths, one is connected to the input end of the control circuit breaker, and the other is connected to the contactor corresponding to each driving motor. The output end of the control circuit breaker is connected to the 24V power supply, and the 24V power supply is connected to the power module in the driving controller. The contactor is used to control the rotation of the corresponding driving motor, thereby controlling the movement of the driving. The alarm light is connected to the second relay and controlled by the second relay.

[0042] Example 3:

[0043] like Figure 1 As shown, a vehicle control system includes the vehicle control box shown in Example 2, further comprising limiters mounted at both ends of the vehicle track, control buttons, capacitive proximity sensors mounted on the vehicle driven wheels, an environmental controller, and several vehicle motors. The limiters are used to transmit vehicle limit information, the control buttons transmit button input information, the capacitive proximity sensors transmit slip detection information, the environmental controller is a central controller for controlling multiple vehicle controllers, and the vehicle motors drive the corresponding vehicles along the vehicle track. In this embodiment, when the vehicle limit information or slip detection information is abnormal, the motors are stopped and an alarm is output through the alarm output module.

[0044] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0045] 1. The crane controller is installed in the crane control box in the chicken house, integrating all the control circuits that originally needed to be composed of relays and motor protectors into the control board, effectively reducing the wiring difficulty in the crane control box and reducing device costs;

[0046] 2. The crane control system includes two working modes: manual and automatic control. Manual control is to control the relay on the main control panel through the external control button to control the forward or reverse movement of the crane. Automatic control is to control the material feeding at a fixed time through the controller external screen or the connection to the environmental controller, and to achieve material feeding distance control in conjunction with slip detection.

[0047] 3. The driving control system integrates functions such as current detection and limit detection. The vehicle will not overshoot or stop when slipping during operation, ensuring driving safety.

[0048] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
