Fig. 2 is a block diagram illustrating a capacitance monitoring circuit 123 according to an embodiment of the present invention. The intelligent power management system of the present invention is described below with reference to fig. 1 and 2.

As shown in fig. 1, the present invention provides an intelligent power management system, comprising: an electrical information collection circuit 120, a safety information collection circuit 140, and a first controller 150. The electrical information acquisition circuit 120 can be an intelligent network power meter, can be customized on the basis of the power monitoring requirement of the breeding field, is used for measuring commonly used power parameters, has a perfect communication networking function, can send the measurement result to the first controller 150 or other equipment through a wireless network or a wired network, is an intelligent and digital acquisition element, and can directly replace a conventional power transmitter and a measurement meter. Which may be disposed within a first level of power distribution equipment 110 (e.g., a power distribution room) to collect electrical information within the first level of power distribution equipment 110 (e.g., equipment such as a high voltage inlet room, a high voltage switchgear, a high voltage outlet cabinet, and a low voltage power distribution room). The electrical information may include information such as current, voltage, real power, reactive power, apparent power, power factor, forward active power, reverse active power, and zero sequence current. In one embodiment, the intelligent network power meter can be connected to the line protection device of the high-voltage switch cabinet to collect the electrical information of the power supply line.

The electrical information collecting circuit 120 may be configured to collect the electrical information, and further include a capacitance monitoring circuit configured to collect switching actions of a capacitance loop (e.g., a capacitance loop in a capacitance cabinet) in the first-stage power distribution device 110. As shown in fig. 2, in one embodiment, the capacitance monitoring circuit may include a capacitance information collector 1232, and for monitoring, one capacitance information collector 1232 may be provided for each livestock shed in the farm. The capacitance information collector 1232 is connected to a capacitance compensation controller 1233. The capacitance compensation controller 1233 is connected to a capacitance switching switch monitoring circuit to obtain the switching state of the capacitance loop, so as to control the capacitance compensation. Further, in an embodiment, the capacitance information collector 1232 may be an expandable modular controller, and may be connected with a capacitance monitoring expansion module 1231, where the capacitance monitoring expansion module 1231 may be an input module of a 16-way digital RS-485 interface, and is configured to collect an open state and a close state of the switching capacitor contactor (i.e., an on-off state of a coil of the switching capacitor ac contactor), and send collected information to the capacitance information collector 1232. The capacitance information collector 1232 may be connected to the first controller 150 to send the switching status of the capacitance loop in the capacitance cabinet to the first controller 150. By monitoring the opening and closing states of the switched capacitor contactor, the switching state of the capacitor circuit in the capacitor cabinet can be further verified, and further, the fault in monitoring the switching state of the capacitor circuit in the capacitor cabinet by the capacitance compensation controller 1233 is prevented. Therefore, the service efficiency of the power grid can be more effectively guaranteed under the dual monitoring of the capacitance compensation controller 1233 and the capacitance monitoring expansion module 1231.

In one embodiment, the electrical information collection circuit 120 may further include a first residual current transformer for detecting a residual current of the circuit in the first stage power distribution device 110 and sending the measurement result to the first controller 150. For example, a first residual current transformer is provided on the mains loop of the outlet cabinet to monitor the residual current thereof. When the residual current received by the first controller 150 exceeds the residual current threshold preset in the first controller 150, the first controller 150 will alert the operator that the residual current is large. The staff will make corresponding treatment according to the warning, such as timely power off and circuit maintenance. Therefore, the condition of the electric leakage of the loop in the first-stage power distribution equipment 110 can be found and processed in time, so that stable power supply of the culture field can be guaranteed, and meanwhile, the power supply safety of the culture field is guaranteed.

In order to facilitate collection and statistics of the power information, in an application scenario, an intelligent network power meter may be arranged on each outgoing line loop of each power distribution room switch cabinet, address planning is performed by using a communication address of a MODBUS protocol (a serial communication protocol), a communication address is allocated to each intelligent network power meter, and finally, the first controller 150 collects information of each different communication address, so as to complete collection of data collected by each intelligent network power meter.

The framework of the intelligent power management system, the electrical information collection circuit 120 and the capacitance monitoring circuit of the embodiment of the utility model is exemplarily described above with reference to fig. 1 and 2. It should be understood by those skilled in the art that the frame structure is exemplary and not limiting, and that the frame may be adjusted as desired by those skilled in the art. Fig. 3 is a block diagram illustrating the security information acquisition circuit 140 according to an embodiment of the present invention. Fig. 4 is a wiring diagram showing the security information acquisition circuit 140 according to the embodiment of the present invention. The security information acquisition circuit 140 is described below with reference to fig. 3 and 4.

The safety information acquisition circuit 140 may be disposed within the second stage power distribution equipment 130 (e.g., a power distribution box within a livestock house). In one implementation scenario, the safety information collecting circuit 140 is mainly used to collect safety information of the second-stage power distribution equipment 130, where the safety information may include information of current, voltage, power, zero-sequence current, cable temperature, and the like. As shown in fig. 3 and 4, in one embodiment, the security information acquisition circuit 140 may include a security information acquisition controller 145 and various information acquisition devices connected to the security information acquisition controller 145. The safety information collection controller 145 is connected to the first controller 150 (e.g., wirelessly) and the current transformer 144 is connected to the safety information collection controller 145 for detecting the current in the loop of the second stage power distribution device 130. In one embodiment, the safety information collection controller 145 is further connected to a second residual current transformer 141, and the second residual current transformer 141 is used for detecting a residual current of a loop in the second stage power distribution device 130. In one implementation, the safety information collection controller 145 is further coupled to a temperature sensor 142, such as an NTC (negative temperature coefficient) temperature probe, for detecting the temperature of the wires within the secondary distribution device 130. Meanwhile, the safety information collection controller 145 is further connected to a voltage sampling circuit 143. In order to facilitate information collection and management, in one embodiment, a safety information collection controller 145 may be disposed in each distribution box for collecting the measurement information; meanwhile, a gateway module can be arranged in each distribution box, and the safety information acquisition controller 145 is in communication connection with other relevant information acquisition units through the gateway module, so that the safety information acquired by the other relevant information acquisition units is collected.

After the electrical information collection circuit 120 and the safety information collection circuit 140 respectively collect the corresponding electrical information and safety information as described above, the electrical information and safety information are transmitted to the first controller 150. The first controller 150 determines the operational status of the first stage power distribution device 110 based on the electrical information and determines the operational status of the second stage power distribution device 130 based on the safety information. While the first controller 150 includes a communication unit for enabling data communication between the first controller 150 and other devices. In addition, the first controller 150 is further connected to a first display screen 160, which is convenient for the staff to visually check the electrical information, the safety information and various kinds of early warning information.

In one embodiment, an alarm threshold of the portion of the electrical information, such as a current alarm threshold, a voltage alarm threshold, a zero sequence current alarm threshold, etc., may be preset in the first controller 150. Wherein the current alarm threshold may include a power outage alarm threshold and an overcurrent alarm threshold. When the current acquired by the first controller 150 from the electrical information acquisition circuit 120 is less than or equal to the power failure warning threshold, the first controller 150 sends a power failure warning to the mobile terminal carried by the worker through an intelligent mobile office platform such as a nail or in a manner of sending a short message or making a call. When the current is greater than or equal to the over-current warning threshold, the first controller 150 will issue an over-current warning to the operator. Likewise, the voltage alarm threshold may include an under-voltage alarm threshold and an over-voltage alarm threshold. When the voltage acquired by the first controller 150 from the electrical information acquisition circuit 120 is less than or equal to the under-voltage warning threshold, the first controller 150 will also issue an under-voltage warning to the staff; when the voltage is greater than or equal to the overvoltage warning threshold, the first controller 150 will issue an overvoltage warning to the operator. After receiving the fault alarm sent by the first controller 150, the worker can perform targeted operation in time, thereby realizing real-time fault alarm and work order delivery.

In one implementation scenario, alarm thresholds for various safety information, such as a current alarm threshold, a voltage alarm threshold, a zero sequence current alarm threshold, a cable temperature alarm threshold, etc., may also be preset in the first controller 150. The first controller 150 obtains the safety information such as the current, the voltage, the zero sequence current, the cable temperature and the like of the loop in the second-stage distribution equipment 130 from the safety information acquisition controller 145, when the first controller 150 judges that a certain safety information exceeds the alarm threshold range, for example, the alarm threshold of the cable temperature is 30 ℃, and when the cable temperature received by the first controller 150 exceeds 30 ℃, the first controller 150 sends a safety alarm that the cable temperature is too high to the working personnel. Or for example, the zero sequence current alarm threshold is 1A, when the zero sequence current received by the first controller 150 exceeds 1A, the first controller 150 will issue a safety warning that the cable temperature is too high to the working personnel. Thus, effective fire risk avoidance may be achieved. In one embodiment, the first controller 150 is further coupled to a memory 170 to store the electrical information, safety information, and alarm records described above to retrieve data at any time. Meanwhile, the memory 170 can calculate the load rate of the power system of the farm according to the electrical information and the safety information.

In practical operation, the intelligent power management system may further include a second controller, and the electrical information collection circuit 120 and the safety information collection circuit 140 are connected to the first controller 150 through the second controller. After the electrical information collection circuit 120 and the safety information collection circuit 140 respectively collect the corresponding electrical information and safety information as described above, the electrical information and safety information are sent to the second controller, and the second controller sends the electrical information and safety information to the first controller 150. Meanwhile, the second controller is further connected with a second display screen, so that local workers can check the electrical information and the safety information conveniently at any time. The second controller is equivalent to the front data collector of the first controller 150, and is mainly used for summarizing the electrical information collected by the electrical information collection circuit 120 and the safety information collected by the safety information collection circuit 140, and visually displaying the electrical information and the safety information to the staff through the second display screen. The second controller may not analyze and process the electrical information and the safety information. The main body that analyzes, processes, and emits various warning information on the electrical information and the safety information may be the first controller 150.

In addition to monitoring the states of the first-stage power distribution equipment 110 and the second-stage power distribution equipment 130, in an application scenario, the intelligent power management system may further include a power generation information acquisition circuit, where the power generation information acquisition circuit may be an intelligent network power meter, and is used to monitor the operating state of the generator room (e.g., output ac voltage, current, frequency of the generator, fire alarm information in the generator room, etc.). Meanwhile, the intelligent network power meter can be connected with the first controller 150, so that the first controller 150 can perform real-time monitoring and abnormal early warning on the running state of the generator. In a real-time mode, an intelligent network power meter can be configured for each generator, so that the operation parameters of the generators can be conveniently acquired in a one-to-one mode.

In summary, the first controller 150 monitors the states of the current, the voltage, the zero sequence current, the capacitor loop and the like in the first-stage distribution equipment in real time according to the electrical information fed back by the electrical information acquisition circuit 120 in the form of RS485 communication, and can perform early warning and work order dispatch through the early warning logic and the work order dispatch logic in the first controller 150. Similarly, the first controller 150 may also monitor the states of the current, the voltage, the zero-sequence current, and the like of the loop in the second-stage power distribution device in real time according to the safety information fed back by the safety information acquisition circuit 140 in the form of RS485 communication, and may also perform early warning and work order dispatch by using early warning logic and work order dispatch logic provided in the first controller 150. Therefore, the electric power data acquisition, the state monitoring, the fault alarm, the work order dispatching, the data storage, the remote control and the like of the electric power system of the culture site can be realized, and the visual management of the minimum granularity is provided for the culture site. Meanwhile, the overall detection and the platform management of the power supply system of the farm area are realized.
