Description

Technical Field

[0001] The present invention generally relates to the technical field of farm fault alarms, and more specifically, to a farm fault detection alarm system. Background Art

[0002] With the increasing number of electrification, intelligent and automated equipment in farms, the issue of electricity safety in farms is becoming more and more important. In order to ensure the safety of electricity use in farms, fault detection and alarm systems are installed in farms. For example, voltage transformers, current transformers and other power sensors are installed on the power supply lines of electrical equipment to detect the voltage and current information on the power supply lines. When the voltage and current on the power supply lines are abnormal, an alarm is issued through an alarm to remind the staff to take timely measures to prevent the further spread of the fault.

[0003] At present, most of the fault detection alarm systems in farms are installed in each breeding unit in the breeding house. When the power supply of a breeding unit is abnormal, the corresponding fault detection alarm system can send an alarm signal to the staff. Since the existing alarms are mainly sound and light alarms, the alarm signals sent by such alarms have a limited transmission distance. In the breeding house of a large breeding farm, if the staff is far away from the alarm or is outside the breeding house, they may not receive the alarm signal sent by the alarm, so the reliability of this alarm method is poor.

[0004] From the above, it can be seen that the farm fault alarm system in the prior art has the problem of poor reliability. Summary of the invention

[0005] The present invention provides a farm fault detection alarm system, which is used to at least solve the problem of poor reliability of the farm fault alarm.

[0009] According to another embodiment of the present invention, the electric energy sensor includes a voltage transformer and / or a current transformer, which is used to obtain the electric energy information of the electrical equipment in the breeding farm.

[0010] According to another embodiment of the present invention, the in-house controller is also connected to a whole row alarm, and the whole row alarm is used to be installed in the breeding unit row where the breeding unit corresponding to the in-house alarm device is located to issue breeding unit row alarm information.

[0011] According to another embodiment of the present invention, it further includes an in-house wireless signal transmitter, which is connected to the entire row of alarms and is used to obtain the working status of the entire row of alarms and send alarm information to the user.

[0012] According to another embodiment of the present invention, it also includes a second contactor, the coil of which is connected in parallel with the entire row of alarms, and the contacts are connected to the wireless signal transmitter in the house. The wireless signal transmitter in the house is used to obtain the action signal of the contact of the second contactor and send an alarm message to the user terminal.

[0013] According to another embodiment of the present invention, the in-house alarm unit further includes a third contactor, the coil of the third contactor is connected in parallel with the in-house alarm, and the contacts are used to be arranged on the line between the fan and the power supply.

[0015] According to another embodiment of the present invention, the indoor environment detection device also includes a fourth contactor, the indoor controller is connected to the coil of the fourth contactor, one end of the fourth contactor contact is used to connect to a power supply, and the other end is connected to the indoor alarm and the coil of the first contactor.

[0016] According to yet another embodiment of the present invention, it further includes a fifth contactor, and the fifth contactor is redundantly arranged with the first contactor.

[0017] The technical solution provided by the present invention includes an alarm device installed in a breeding farm and an alarm device installed outside a breeding farm. The controller in the alarm device can detect whether there is a fault in the electrical equipment in the breeding farm through an electric energy sensor. If there is a fault, the alarm device in the breeding farm can be controlled to send an alarm signal inside the breeding farm, and the coil of the first contactor can be controlled to be energized. When the coil of the first contactor is energized, its contacts will generate a corresponding action signal.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 , Figure 1 Shown is a farm fault detection alarm system provided by the present application, which is used to detect faults in the farm and send out alarm signals inside and outside the farm house when a fault is detected, so as to remind relevant personnel to take timely measures.

[0028] like Figure 1 As shown, the farm fault detection alarm system provided by the present application includes an indoor alarm device and an outdoor alarm device, wherein the indoor alarm device includes an indoor controller, an electric energy sensor, an indoor alarm BELL1 (a buzzer or an audible and visual alarm may be used) and a first contactor TK1, and the outdoor alarm device includes an outdoor controller and an outdoor alarm device BELL2 (an audible and visual alarm may be used). Figure 1 In the farm fault detection and alarm system shown, both the outdoor controller and the indoor controller use PLC, and the power ports of the outdoor controller and the indoor controller are connected to the live wire L, the voltage of the live wire L is 220V AC voltage, which can power the outdoor controller and the indoor controller.

[0029] The farm fault detection alarm system provided in the present application is a house alarm device used to be installed inside the breeding house of the farm. The first contactor TK1 is an AC contactor, one end of its coil is connected to an output port of the house controller, and the other end is connected to the neutral line N1; one end of the house alarm BELL1 is connected to an output port of the house controller, and the other end is connected to the neutral line N1. Figure 1 Taking the structure shown as an example, the coil of the first contactor TK1 is connected in parallel with the in-house alarm unit BELL1, and then one end is connected to an output port of the in-house controller, and the other end is connected to the neutral line N1. This setting method can ensure that the in-house alarm unit BELL1 and the first contactor KT1 are triggered at the same time, and on the other hand, it can reduce the number of output ports used by the in-house controller.

[0030] The farm fault detection alarm system provided by the present application, the outdoor alarm device is used to be installed outside the breeding house of the farm, one end of the outdoor alarm BELL2 is connected to the outdoor controller, and the other end is connected to the neutral line N1; the contact of the first contactor TK1 is connected to the input port of the outdoor controller, when the contact of the first contactor TK1 is actuated, the outdoor controller can receive a corresponding action signal, for example, when one end of the contact of the first contactor TK1 is connected to the input port of the outdoor controller and the other end is grounded, if the contact of the first contactor TK1 is closed, the input port of the outdoor controller can receive a low potential signal, if the contact of the first contactor TK1 is closed, the input port of the outdoor controller is in a suspended state; and again Figure 1 In the farm fault detection and alarm system shown, one end of the contact of the first contactor TK1 is connected to the positive pole of the power supply, and the other end is connected to an input port of the controller outside the house. When the contact of the first contactor TK1 is opened and closed, the connection between the input port of the controller outside the house and the power supply is also connected or disconnected accordingly, that is, when the contact of the first contactor TK1 is actuated, the controller outside the house can receive the corresponding action signal.

[0031] In the farm fault detection alarm system of this embodiment, the outdoor alarm device is an alarm device installed outside the breeding house, which is used to send an alarm signal outside the breeding house to send an alarm message to the staff outside the breeding house. The indoor alarm device is an alarm device installed at the breeding unit in the breeding house. When there are multiple breeding units in the breeding house, the farm fault detection alarm system has multiple indoor alarm devices, each of which is respectively installed at the corresponding breeding unit in the breeding house, and the connection method between each indoor alarm device and the outdoor alarm device is the same as that of the indoor alarm device. Figure 1 The connection method between the alarm device inside the house and the alarm device outside the house is the same.

[0032] The farm fault detection alarm system provided in this application works as follows:

[0033] The controller inside the house determines whether there is any abnormality in the power supply system of the breeding house based on the data detected by the electric energy sensor. If so, the controller controls the output voltage connected to the coil of the first contactor TK1 and the output port connected to the alarm BELL1 inside the house, so that the coil of the first contactor TK1 and the alarm BELL1 inside the house are energized; after the alarm BELL1 inside the house is energized, an alarm signal is issued to remind the staff inside the house to take measures to eliminate the fault; after the coil of the first contactor TK1 is energized, the contacts are closed to connect the power supply to the corresponding input port on the controller outside the house, and the pin on the controller outside the house receives the action signal of the contact of the first contactor TK1; when the controller outside the house receives the action signal of the contact of the first contactor TK1, it controls the output voltage of the output port connected to the alarm BELL2 outside the house, so that the alarm BELL2 outside the house sends an alarm signal to remind the staff outside the house to take measures.

[0034] In summary, the farm fault detection alarm system provided by the present application, the controller inside the house is connected to the coil of the first contactor TK1, and the controller outside the house is connected to the contact of the first contactor TK1. When the controller outside the house controls the alarm BELL1 inside the house, it can also control the contact action of the first contactor TK1, so that the controller outside the house receives the corresponding signal. Due to the technical solution provided by the present application, when a breeding unit fails, an alarm signal can be issued simultaneously inside and outside the breeding house of the breeding farm, reminding the staff inside and outside the breeding house to take timely measures. Therefore, compared with the method of only issuing an alarm in the breeding house in the prior art, the reliability of the fault alarm can be improved.

[0035] The above article provides an overall introduction to the farm fault detection and alarm system. The following article explains the outdoor alarm device in combination with specific application scenarios.

[0036] In an application scenario, the outdoor controller is also connected to an outdoor communication module, which can be a wired communication module such as an RS485 communication module, a CAN communication module, or a wireless communication module such as a USR network communication module, a GPRS network communication module, etc. The outdoor controller can establish a communication connection with a user terminal (such as a mobile phone, a tablet computer, a computer, etc.) through the outdoor communication module. After the outdoor controller obtains the action signal of the contact of the first contactor KT1, it can send an alarm message to the user terminal through the communication module, so that the user can receive the alarm message on the user terminal and know that a fault has occurred in the farm.

[0037] The above article has given a detailed description of the outdoor alarm device. The following article will give a detailed introduction to the indoor alarm device based on specific application scenarios.

[0038] In one application scenario, the power sensor includes a voltage transformer and a current transformer. There are multiple breeding units in the breeding house of the farm, and each breeding unit is equipped with corresponding electrical equipment, such as lighting, fans, heaters, etc. The electrical equipment of each breeding unit is connected to the power supply system through the corresponding power supply line. Take the power supply line of the electrical equipment of one breeding unit as an example. Figure 2 As shown, the power supply line of the electric equipment of the breeding unit includes an A-phase line, a B-phase line, a C-phase line and an N-phase line, and a circuit breaker KD1 is arranged on the power supply line, that is, the power supply line of the electric equipment of the breeding unit is a three-phase four-wire power supply line. The current transformer PT1 and the voltage transformer PT2 of the electric energy sensor, the current transformer PT1 is arranged on each phase line, and is used to detect the current of each phase line, and the voltage transformer PT2 is arranged on each phase line, and is used to detect the voltage of each phase line. The controller in the house can detect the voltage information and current information on the power supply line of the breeding unit according to the voltage transformer PT1 and the current transformer PT2, and judge whether there is a fault in the power supply of the electric equipment in the breeding unit according to the acquired voltage information and current information.

[0039] In another application scenario, such as Figure 3 As shown, the in-house controller is also connected to a row of alarms BELL3. A plurality of breeding units are provided in the breeding house of the farm, and the breeding units are distributed in rows and columns and arranged into a plurality of breeding unit rows, and each breeding unit row has a plurality of breeding units. The breeding farm fault detection alarm system provided in this embodiment is provided with an in-house alarm device for each breeding unit, and each breeding unit row has a row of alarms, and the in-house controller in each in-house alarm unit is connected to the corresponding row of alarms. When the in-house controller determines that a corresponding breeding unit has a fault, it also controls the corresponding in-house alarm to send out an alarm signal. When a fault is detected, not only the corresponding in-house alarm is controlled to send out an alarm signal, but also the corresponding row of alarms is controlled to send out an alarm signal. Figure 3 Taking the structure shown as an example, the in-house controller is connected to the positive pole of the whole row of alarms BELL3, and the negative pole of the whole row of alarms BELL3 is connected to the neutral line N2. The difference between the neutral line N1 and the neutral line N2 is that they are located at different positions in the breeding facility. When the in-house controller determines that there is an abnormality in the breeding unit, it controls the whole row of alarms BELL3 to send out the whole row alarm information. In the arrangement of this embodiment, when a fault occurs, the staff can obtain the row where the faulty breeding unit is located based on the whole row of alarms BELL3 that send out the alarm signal, and then find the faulty breeding unit in the row based on the in-house alarm BELL1, thereby improving the efficiency of determining the location of the breeding unit.

[0040] Furthermore, in another application scenario, the farm fault detection alarm system also includes an in-house wireless signal transmitter, which is connected to the entire row of alarms BELL3 to obtain the working status of the entire row of alarms BELL3. For example, a voltage sensor is set to detect the voltage across the entire row of alarms BELL3, and the voltage across the entire row of alarms BELL3 is used to determine whether it is in a working state. The in-house wireless signal transmitter is also wirelessly connected to the user terminal of the staff. When the entire row of alarms BELL3 sends an alarm signal, the in-house wireless signal transmitter can send information to the user terminal to give the user a remote alarm.

[0041] Below Figure 4 Taking the method shown as an example, the connection method between the wireless signal transmitter in the house and the whole row of alarms BELL3 is introduced in detail. It can be understood that Figure 4 The structure shown is exemplary and not restrictive, and the above description of the whole row of alarms BELL3 and the wireless signal transmitter in the house is also applicable to the following description of the whole row of alarms BELL3 and the wireless signal transmitter in the house. Figure 4 Description.

[0042] like Figure 4 As shown, the farm fault detection alarm system also has a second contactor KT2, which is an AC contactor, and the coil is connected in parallel with the whole row of alarms BELL3, and the two ends of the contact are respectively connected to an input port and an output port in the wireless signal transmitter in the house. When the controller in the house controls the whole row of alarms BELL3 to work, the whole row of alarms BELL3 is powered, and the coil of the second contactor KT2 is also powered. After the coil of the second contactor KT2 is powered, the contact moves, and the on-off state between the input port and the output port connected to the two ends of the contact of the second contactor KT2 in the wireless signal transmitter in the house changes. Therefore, the wireless signal transmitter in the house can judge whether there is an alarm signal from the whole row of alarms BELL3 according to the change of the on-off state; if the alarm signal is sent by the whole row of alarms BELL3, the wireless signal transmitter in the house sends the alarm information to the user terminal through a communication connection with the user terminal through a text message or the like.

[0043] In another application scenario, each breeding unit in the breeding house is equipped with a corresponding fan, and the alarm in the house also includes a third contactor KT3, such as Figure 5 As shown, the third contactor KT3 is an AC contactor and is connected to the fan in the corresponding breeding unit. When a breeding unit fails, the fan can be controlled to start working to speed up the air flow in the breeding unit and improve the air quality in the breeding unit. Figure 5In the embodiment, one end of the coil of the third contactor KT3 is connected to the corresponding in-house controller, and the other end is connected to the neutral line N1, such as being connected in parallel with the in-house alarm BELL1; the contact of the third contactor KT3 is connected in series to the line of the corresponding fan power supply end connected to the power supply, when the in-house controller controls the in-house alarm BELL1 to send an alarm signal, the in-house alarm BELL1 is energized, and at the same time, the coil of the third contactor KT3 is energized, the contact is closed, the fan is connected to the power supply and energized, and the fan starts to work after being energized, speeding up the air flow in the breeding unit. The setting method of this embodiment can control the fan to speed up the air flow in the breeding unit when a fault occurs in the breeding unit, so that the air in the breeding unit remains clean, thereby ensuring the healthy growth of the livestock in the breeding unit.

[0044] The following is a further detailed introduction to the farm fault detection and alarm system.

[0045] In one embodiment, the in-house alarm device also includes an environmental controller, which is connected to an environmental detection sensor and is connected to the in-house alarm and the coil of the first contactor KT1. The environmental controller is used to obtain environmental information in the corresponding breeding unit through the environmental detection sensor, and judge whether there is any abnormality in the environment in the breeding unit based on the detected environmental information. If so, the in-house alarm is controlled to send an alarm signal, and the coil of the first contactor KT1 is controlled to be energized, so that the contacts of the first contactor TK1 are actuated.

[0046] Below Figure 6 Taking the method shown in the figure as an example, the connection method between the environment controller and the alarm BELL1 in the house and the coil of the first contactor KT1 is introduced in detail. It can be understood that Figure 6 The structure shown is exemplary and not restrictive, and the description of the environmental controller, the indoor alarm BELL1, and the first contactor KT1 in the above text is also applicable to the following description of the environmental controller. Figure 6 Description.

[0047] by Figure 6Taking the structure shown as an example, the indoor alarm device also includes a fourth contactor KT4, which is an AC contactor, and the two ends of the coil are respectively connected to an input port and an output port of the environmental controller, one end of the contact is connected to the live wire L, and the other end is connected to the coil of the first contactor KT1 and the positive pole of the power supply end of the indoor alarm. The environmental detection sensor can detect the environmental information of the corresponding breeding unit, and the environmental controller can obtain the environmental information of the corresponding breeding unit according to the environmental detection sensor, and when the environment of the corresponding breeding unit is abnormal, the coil of the fourth contactor KT4 can be controlled to be energized, so that the contact of the fourth contactor KT4 is closed; when the contact of the fourth contactor KT4 is closed, the positive pole of the power supply end of the indoor alarm BELL1 and the coil of the first contactor KT1 are connected to the live wire L, the indoor alarm BELL1 sends an alarm signal and the contact of the first contactor KT1 is closed. The setting method of this embodiment can make the indoor alarm BELL1 and the outdoor alarm BELL2 send alarm signals when the environment in the breeding unit is abnormal, thereby improving the reliability of environmental monitoring in the breeding unit.

[0048] Furthermore, in another embodiment, the above-mentioned environment detection sensor includes a temperature sensor and a humidity sensor, which are respectively used to detect the temperature information and humidity information in the breeding unit. The environment controller can obtain the temperature information and humidity information in the breeding unit according to the temperature sensor and the humidity sensor. When the temperature and humidity in the breeding unit are not within the set range, it is determined that the environment in the pig house is abnormal. The setting method of this embodiment can monitor the temperature and humidity in the breeding unit, thereby improving the reliability of the temperature and humidity control of the breeding house.

[0049] The following is a further explanation of the farm fault detection alarm system

[0050] like Figure 7 As shown, in an application scenario, the farm fault detection alarm system also includes a fifth contactor KT5, which is an AC contactor and is redundantly set with the first contactor KT1, that is, the coil of the fifth contactor KT5 is set in parallel with the coil of the first contactor KT1, and the contact of the fifth contactor KT5 is set in parallel with the contact of the first contactor KT1. When the controller in the house controls the coil of the first contactor KT1 to be energized, the coil of the fifth contactor KT5 is also energized, and the contacts of the first contactor KT1 and the second contactor KT5 are closed at the same time, thereby ensuring the reliability of signal transmission to the controller outside the house. The setting method of this embodiment, which redundantly sets the first contactor KT1 and the fifth contactor KT5, can improve the reliability of the connection between the alarm device in the house and the alarm device outside the house, and thus can improve the reliability of the farm fault detection alarm system.
