[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described in the drawings here can be arranged and designed in various different configurations.

[0057] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0058] In the description of this application, it should be noted that relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0059] The term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0060] In existing feed mills, signals are transmitted using wires, which has the following disadvantages:

[0061] 1. The feed factory environment is complex and there are many interference sources, which leads to signal distortion and attenuation, and even weakens to the extent that the equipment cannot be controlled normally;

[0062] 2. Wires are easily chewed by mice, affecting the stability of transmission.

[0063] To overcome the above problems, please refer to Figure 1 The embodiment of the present application provides a feed mill signal transmission system, including a production device 10, an optical fiber transmission module 20 and a control device 30. The production device 10 is a feed production device used for producing feed. The control device 30 is used to receive a signal fed back by the production device 10 and send a control signal to the production device 10.

[0064] The optical fiber transmission module 20 includes a first optical-to-electrical converter 201 , an optical cable 202 , and a second optical-to-electrical converter 203 .

[0065] The production equipment 10, the optical fiber transmission module 20 and the control equipment 30 have the following connection relationship:

[0066] The production equipment 10 is connected to the electrical signal end of the first photoelectric converter 201, and the optical signal end of the first photoelectric converter 201 is connected to the first end of the optical cable 202;

[0067] The second end of the optical cable 202 is connected to the optical signal end of the second photoelectric converter 203, and the electrical signal end of the second photoelectric converter 203 is connected to the control device 30. The electrical signal end of the photoelectric converter can be, for example, a PROFIBUS-DP bus communication interface.

[0068] The production equipment 10 and the control equipment 30 are located in different rooms, such as Figure 2The production equipment 10 is located in the production room 40, and the control equipment 30 is located in the central control room 50. The first photoelectric converter 201 can be arranged in the production room 40, and the second photoelectric converter 203 can be arranged in the central control room 50. The optical cable undertakes the signal transmission over a long distance between the production room 40 and the central control room 50. The first photoelectric converter 201 and the second photoelectric converter 203 can play a role in signal enhancement.

[0069] Optical cable transmission is applied to the signal transmission system of feed mills and has the following advantages:

[0070] 1. Compared with the copper wire rate of 1.54MHz per second, the optical fiber network has an operating rate of 2.5GB per second. From the perspective of bandwidth, optical fiber has a larger information capacity. Under the condition of the same information rate, smaller cables can be used;

[0071] 2. Optical fiber uses light pulses to transmit information along optical lines instead of using electrical pulses to transmit information along cables. Optical fiber has a large impedance to electromagnetic noise such as radio, motor or other adjacent cables, making it immune to interference from electrical noise; optical fiber transmission has the advantages of low attenuation, wide bandwidth, strong anti-interference and high safety performance;

[0072] 3. From the perspective of long-term maintenance, the long-term maintenance cost of optical cables will be very low; the glass material used in optical fibers is non-conductive and will not produce sparks due to circuit breaks, lightning strikes, etc., so it is highly safe and is particularly suitable for flammable and explosive occasions.

[0073] The number of the above production equipment may be greater than 1, and two or more production equipment may be connected to the electrical signal end of the first photoelectric converter 201 via a copper wire cable.

[0074] like Figure 3 , Figure 4 , a bus module 60 can be designed, and two or more production devices 10 are connected to the first photoelectric converter 201 via a bus, that is, two or more production devices 10 are connected to the bus module 60, and the bus module 60 is connected to the electrical signal end of the first photoelectric converter 201.

[0075] The production equipment 10 may specifically include a mixer, an oil tank, a molasses tank and a pipeline system. The pipeline system may include a pipeline from the oil tank to the mixer, a pipeline from the molasses tank to the mixer, etc. Heaters may be provided in the oil tank, the molasses tank and the pipeline system, and the heaters are all connected to the electrical signal end of the first photoelectric converter 201.

[0076] Liquids may become more viscous at low temperatures. Heating oil tanks and their pipelines can prevent the liquid from becoming too viscous or even solidifying under low temperature conditions in winter, thereby affecting the production process and product quality.

[0077] On the other hand, the heating amount cannot be too large, and too high a temperature will also affect the product quality, so temperature sensors can be set in the oil tank, molasses tank and pipeline system, and the temperature sensors are connected to the electrical signal end of the first photoelectric converter 201. Thus, the control device 30 can control the power of the heater according to the signal of the temperature sensor.

[0078] The mixer is connected to the electrical signal end of the first photoelectric converter 201 and communicates with the control device 30. The control device 30 can also control the running time of the mixer. When stirring is required, stirring is performed for a set time length. On the one hand, the stirring time will not be too short to achieve a sufficiently uniform mixing effect. On the other hand, the stirring time will not be too long to avoid excessive energy consumption.

[0079] The production equipment 10 may further include a scale, a pump, a flow sensor, etc. The flow sensor, the scale, and the pump may all be connected to the electrical signal end of the first photoelectric converter 201 .

[0080] The scale can weigh the raw materials in a container such as an oil tank. When a specific volume of raw materials needs to be added to a container, the control device 30 can control the pump to run and detect the amount of raw materials added to the container through the scale or flow sensor. When the amount of raw materials reaches the required weight, the control device 30 can control the pump to stop according to the signal of the scale.

[0081] The accurate weight of various raw materials can be obtained through the scale of the container. After obtaining the accurate weight of the raw materials, they can be transported to the mixer. The mixer mixes them according to the set time to obtain products with stable quality.

[0082] Feed mill signal transmission system can also be applied to the communication between fire control equipment and fire equipment, such as Figure 5 The feed factory signal transmission system includes a fire control device 70, a fire equipment 80 and an optical fiber transmission module 20.

[0083] The fire fighting equipment 80 and the fire fighting control equipment 70 are located in different rooms. The fire fighting equipment 80 can be located in the production room 40. The fire fighting control equipment 70 can be located in the central control room 50, or not in the central control room but in the fire fighting control room 90.

[0084] The fire fighting equipment is connected to the electrical signal end of the first photoelectric converter 201, and the optical signal end of the first photoelectric converter 201 is connected to the first end of the optical cable 202. The second end of the optical cable 202 is connected to the optical signal end of the second photoelectric converter 203, and the electrical signal end of the second photoelectric converter 203 is connected to the fire fighting control equipment 70.

[0085] The fire fighting equipment 80 may specifically include a circulation pump and a sprinkler pump, both of which are connected to the electrical signal end of the first photoelectric converter 201 to receive the control signal of the fire fighting control device 70. The circulation pump may maintain appropriate water pressure.

[0086] When the fire-related detection sensor sends out an alarm signal, the fire control device 70 receives the alarm signal and controls the sprinkler pump to operate to extinguish the fire in time.

[0087] The optical cable 202 may be an armored optical cable, which may be divided into the following parts from the inside to the outside:

[0088] (1) Optical fiber: The core part of the optical cable, responsible for transmitting light signals. Optical fiber can be made of glass fiber.

[0089] (2) Buffer layer: One or more layers of material surrounding the optical fiber to protect it from mechanical damage. The buffer layer material can be gel, plastic, etc.

[0090] (3) Armor layer: The protective layer of armored optical cables is usually made of metal or non-metal materials, such as flat fiber reinforced plastics (FRP), steel belt, aluminum belt armor, etc. The armor layer provides additional mechanical protection and has stronger anti-rat performance. For example, the glass fiber in FRP is very thin and brittle. When rats bite, the crushed glass slag will hurt the rats' mouths, making them afraid of optical cables.

[0091] (4) Outer sheath: The outermost layer of the optical cable, usually made of materials such as plastic or rubber, used to resist environmental factors such as ultraviolet rays, moisture, and chemical corrosion.

[0092] Based on the above embodiment, the embodiment of the present application further provides a feed mill structure, including the above feed mill signal transmission system. Among them, different devices and control devices can communicate through different optical fiber transmission modules, and different types of devices can communicate through different optical fiber transmission modules. For example, the production equipment 10 and the control equipment 30 can communicate through the first optical fiber transmission module, and the fire fighting equipment 80 and the fire fighting control equipment 70 can communicate through the second optical fiber transmission module.

[0093] like Figure 6 The feed factory structure includes a production room 40, a fire control room 90, a central control room 50, a production signal transmission system and a fire signal transmission system. The production signal transmission system includes a production device 10, a control device 30 and a first optical fiber transmission module 110. The fire signal transmission system includes a fire control device 70, a fire device 80 and a second optical fiber transmission module 120.

[0094] The production equipment 10 is connected to the control equipment 30 through the first optical fiber transmission module 110. The fire fighting equipment 80 is connected to the fire fighting control equipment 70 through the second optical fiber transmission module 120. The control equipment 30 is located in the central control room 50, the fire fighting control equipment 70 is located in the fire fighting control room 90, and the production equipment 10 and the fire fighting equipment 80 are located in the production room 40.

[0095] like Figure 7 The first optical fiber transmission module 110 and the second optical fiber transmission module 120 may both include a first photoelectric converter, a second photoelectric converter and an optical cable, wherein the optical cable can undertake long-distance transmission across factory buildings and has good signal transmission stability.

[0096] like Figure 8 ,Different devices can also communicate through the same optical fiber transmission module, and both the fire fighting equipment and the production equipment are connected to a first photoelectric converter.

[0097] In general, the present application proposes a feed factory signal transmission system and a feed factory structure. Optical cables are used instead of copper wire cables to transmit signals over long distances between production equipment and control equipment, or between fire-fighting equipment and fire-fighting control equipment, through photoelectric converters and optical fiber communications. The photoelectric converters can enhance the signals, and the optical fibers can maintain good signal stability in sections with the most interference factors. They can also avoid line faults such as short circuits caused by exposed copper wires due to being gnawed by rats in a humid environment. The system has high safety, thereby enhancing the stability of signal transmission of equipment in the feed factory.

[0098] The above-described device and system embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. A person skilled in the art may understand and implement the present embodiment without creative effort.

[0099] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present application should be included in the protection scope of the present application.
