[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not 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.

[0053] To facilitate understanding of this embodiment, the application scenarios and design concepts of the embodiments of the present application are briefly introduced below.

[0054] In the existing construction power management mode, it is impossible to accurately determine the fault type and power outage location when a fault occurs. It requires manual on-site inspection step by step, which consumes a lot of manpower and material resources and has a great impact on the progress of on-site construction. For example, the Tianwan Nuclear Power Project still uses the traditional on-site inspection method of personnel to manage construction power. There is no digital means to monitor the parameters of the distribution cabinet (such as switch status, equipment temperature and humidity, equipment current, voltage and other parameters). Affected by uncertain factors such as the construction environment, aging of distribution cabinet components, variable power load, and personnel skill level, the power equipment cannot determine the power outage location when a fault occurs. It can only rely on the power-off plant feedback on site. After that, according to the power layout diagram, the power-off panel cabinet is checked one by one, and the terminal equipment is cut off in stages to determine the specific location of the fault, and then the fault source is eliminated in a targeted manner. Finally, power supply can be restored. This process requires a lot of manpower, material resources and time, which has a great impact on the progress of on-site construction.

[0055] Based on this, an embodiment of the present application provides a construction power controller to simultaneously collect multiple types of data to facilitate fault diagnosis and locate the fault location.

[0056] Example 1

[0057] The present application provides a construction power controller, which includes: a switch output port 10, a data volume detection port 20, a circuit breaker switch state detection port 30, a switch input port 40 and a main control chip 50.

[0058] The switch output port 10 is electrically connected to the shunt release of the main switch of the power distribution cabinet and is used to control the main switch of the power distribution cabinet.

[0059] The data volume detection port 20 is electrically connected to a sensor or a multi-function electric meter in the power distribution cabinet, and is used to collect operating parameters of the power distribution cabinet.

[0060] The circuit breaker switch state detection port 30 is electrically connected to the output end of the circuit breaker in the power distribution cabinet and is used to collect the output voltage of the circuit breaker; and judge the switch state of the circuit breaker according to the collected signal;

[0061] The switch input port 40 is electrically connected to the door magnetic switch in the power distribution cabinet and is used to collect the open and closed status of the power distribution cabinet door;

[0062] The main control chip 50 , the signal input end of the main control chip 50 is electrically connected to the data volume detection port 20 , the switch input port 40 and the circuit breaker switch state detection port 30 ; the signal output end of the main control chip 50 is electrically connected to the switch output port 10 .

[0063] In the present application, the construction power controller provides multiple types of ports, each type of port has an independent function, and each type of port is connected to different devices in the power distribution cabinet to collect different types of data and transmit them to the main control chip 50. In this way, when the power distribution cabinet operates abnormally, the type of operation fault can be quickly determined, and the construction power controller corresponds to a power distribution cabinet to facilitate the determination of the fault location. In this way, the difficulty of manual troubleshooting can be reduced, the time spent on troubleshooting can be shortened, and engineering costs can be saved.

[0064] Combination Figure 1 As shown, multiple ports are provided on the outside of the construction power controller, including a switch output port 10, a data volume detection port 20, a circuit breaker switch state detection port 30, and a switch input port 40. The positions of these ports can be adjusted in number or position according to usage requirements. In this embodiment, the data volume detection port 20 is set at the upper left position, the switch input port 40 and the switch output port 10 are set at the upper right position, and the circuit breaker switch state detection port 30 is set at the lower position of the construction power controller.

[0065] In this embodiment, 17 circuit breaker switch state detection ports 30 , 2 switch value input ports 40 , 4 switch value output ports 10 and 2 data volume detection ports 20 are used.

[0066] In combination with the first aspect, the main control chip 50 is a 500MHz dual-core industrial-grade main control chip, and the circuit architecture required for connecting with the above-mentioned ports is integrated on the main control chip 50, such as switch input circuit, switch output circuit, circuit conversion architecture, etc.

[0067] In combination with the first aspect, the data volume detection port 20 includes: a first RS485 port and a second RS485 port.

[0068] The first RS485 port is electrically connected to a multi-function electric meter in the power distribution cabinet for collecting power consumption parameters.

[0069] The second RS485 port is electrically connected to the temperature and humidity sensor in the power distribution cabinet and is used to collect temperature and humidity parameters in the power distribution cabinet.

[0070] The data volume detection port 20 is used to collect the operating parameters of the power distribution cabinet, which at least include the temperature and humidity and power parameters in the power distribution cabinet when the power distribution cabinet is running, including operating voltage, current, etc. In this way, the main control chip can monitor the operating parameters of the power distribution cabinet when it is running.

[0071] In combination with the first aspect, the construction power controller further includes: a power supply module electrically connected to the construction power controller for providing electrical energy.

[0072] The power module is responsible for providing power for the entire construction power controller, and its stability and safety directly affect the working state of the control. The power module part achieves qualified power supply through voltage transformation, rectification and filtering.

[0073] The power supply module includes a DC power supply module 61 and an AC power supply module 62 .

[0074] The DC power module 61 is electrically connected to the main control chip 50 and is used to supply power to the main control chip 50. The main control chip 50 is a 500MHz dual-core industrial-grade main control chip.

[0075] The AC power module 62 is electrically connected to an input end of the DC power module 61 .

[0076] Specifically, the AC power supply circuit is responsible for converting the AC220V circuit into a 12V power supply, and the DC power supply circuit is responsible for converting the 12V power supply into 5V, 4V, 1.8V and other power supplies. The working power supply of the main control chip 50 is 4V and 1.8V, and the IO interface is 1.8V. In this embodiment, two groups of level conversion circuits are added, one end is 1.8V, and the other port is 5V. Because the number of IO interfaces of the main control chip 50 is insufficient, three 8-bit parallel reading or serial input shift registers are added to the two groups of level conversion circuits to connect with the 17-way circuit breaker switch state detection port 30 and the switch output port 10 to complete the 17-way AC circuit input and the 3-way door magnetic switch output. At the same time, in this embodiment, four relay outputs and two data volume detection ports 20 are added, one for data processing of the temperature and humidity data, and one for processing various parameters of the electric meter. Three indicator lights, one power indicator light, one network status indicator light, and one data transceiver indicator light.

[0077] In combination with the first aspect, the construction power controller further includes a plurality of status indicator lights, which are electrically connected to the main control chip. In this embodiment, there are three status indicator lights, namely a power indicator light, a network status indicator light, and a data transceiver indicator light, which are electrically connected to the main control chip respectively, and display whether the corresponding circuit connection is in a normal conduction state through the light.

[0078] In combination with the first aspect, the construction power controller also includes: a communication module, which is communicatively connected to the main control chip 50 and the cloud service platform, and is used to transmit the collected data to the cloud service platform.

[0079] Combination Figure 1 As shown, a communication module is also provided between the data volume detection port 20 and the switch quantity input port 40 on the construction power controller. To adapt to the special environment of the nuclear power site, the construction power controller provided in this embodiment adopts a combination of wireless communication and wired communication. The SIM card inserted in the SIM card holder 71 and the antenna connected to the SMA antenna holder can be connected to the server through a mobile data network and / or a network cable to transmit data in real time, so as to transmit the data acquired by the main control chip 50 to the server, thereby helping management personnel to accurately grasp the operating status and various parameters of the distribution cabinet.

[0080] In this embodiment, the construction power controller communication adopts an intranet deployment design and is not directly connected to the public network, thereby ensuring the privacy and reliability of the data.

[0081] In this embodiment, the construction power controller can simultaneously collect parameters such as voltage, current, circuit breaker switch status, temperature and humidity of the distribution cabinet, and door switch status of the distribution cabinet, so as to monitor the status of the distribution cabinet in real time. When a fault occurs, the fault type and location can be determined in the first time, thereby improving the fault handling efficiency and safety performance of the distribution cabinet.

[0082] In a second aspect, the present application provides a power distribution cabinet, in which a construction power controller as described above is provided.

[0083] Combination Figure 1 , Figure 2As shown, the above-mentioned construction power controller is arranged in the distribution cabinet, and the output end of the circuit breaker in the distribution cabinet is connected to the circuit breaker switch state detection port 30 to collect the output voltage of the circuit breaker in the distribution cabinet (corresponding to an output voltage acquisition module), and the switch state is judged according to the collected signal; the intelligent multi-function meter is connected to the first RS485 port in the data volume detection port 20 to collect power parameters; the temperature and humidity sensor in the distribution cabinet is electrically connected to the second RS485 port in the data volume detection port 20 to collect the temperature and humidity conditions in the distribution cabinet; the door magnetic switch in the distribution cabinet is connected to the switch input port 40 to collect the open and closed state of the distribution cabinet door; the shunt release of the main switch of the distribution cabinet is connected to the switch output port 10 to control the switch state of the main switch of the distribution cabinet through the construction power management system.

[0084] In this way, the equipment operating parameters, safety status and environmental data of the distribution cabinets in the distribution system can be monitored in real time around the clock, and the health status and energy efficiency of the distribution system can be grasped anytime and anywhere. When a power supply system fails, the troubleshooting speed can be greatly improved, and the power outage losses can be minimized.

[0085] In a third aspect, the present application provides a construction power management system, including multiple distribution cabinets as described above, and also including a cloud service platform, which is communicatively connected to the construction power controller in each distribution cabinet.

[0086] The abnormal data can be used to quickly locate the abnormal distribution cabinet and the type of abnormal operation of the distribution cabinet.

[0087] In a fourth aspect, the present application provides a construction power management method, which is applied to a cloud service platform in the construction power management system as described above, combined with Figure 3 As shown, the method includes:

[0088] S110, obtaining current operation data transmitted by each construction power controller.

[0089] S120: for each current running data, determine whether the current running data is abnormal.

[0090] If the current operating data is abnormal, execute S130-S150.

[0091] S130, obtaining current distribution cabinet information corresponding to abnormal current operation data.

[0092] S140, determining the upper-level distribution cabinet information and the same-level distribution cabinet information associated with the current distribution cabinet information according to the preset corresponding relationship.

[0093] S150, determining whether there is an abnormality in the first operating data corresponding to the upper-level power distribution cabinet information.

[0094] If the first operating data is abnormal, execute S160 ; if the first operating data is normal, execute S170 .

[0095] S160, determining that the current power distribution cabinet information and all the power distribution cabinet information at the same level are abnormal.

[0096] S170: For each information of the power distribution cabinet at the same level, determine whether the second operation data corresponding to the information of the power distribution cabinet at the same level is abnormal.

[0097] If the second operating data is abnormal, execute step S180 . If all the second operating data are normal, execute step S190 .

[0098] S180: If yes, determine that the current distribution cabinet information and the distribution cabinet information of the same level corresponding to the second operation data are operating abnormally.

[0099] S190, determining that only the current distribution cabinet information is abnormal.

[0100] Combination Figure 3 As shown, in actual application, there is a cascade relationship in the power distribution system. As shown in the figure, the first-level cabinet controls two second-level cabinets, and each second-level cabinet controls two third-level cabinets respectively. The upper-level distribution cabinet will be abnormal only when all the associated distribution cabinets of the same level are abnormal. For example, when any one of the two second-level cabinets is operating normally, the upper-level first-level cabinet is in normal operating state.

[0101] In the present application, the current operating data of each construction power controller is acquired in real time. When abnormal data is found, the information of the current distribution cabinet with abnormal operation is determined according to the preset corresponding relationship; then, the upper-level distribution cabinet information and the same-level distribution cabinet information associated with the current distribution cabinet information are acquired, and it is first determined whether the first operating data corresponding to the upper-level distribution cabinet information is abnormal. If it is abnormal, it can be quickly determined that the current distribution cabinet under the upper-level distribution cabinet information and all the same-level distribution cabinets associated with the current distribution cabinet are abnormal. If the first operating data is normal, it is necessary to judge each distribution cabinet of the same level to determine the final result. In this way, the level to which the abnormal distribution cabinet belongs and which distribution cabinet is abnormal can be locked as soon as possible in the management system of multi-level distribution cabinets.

[0102] Combination Figure 4 For example, if the operating data corresponding to the third-level cabinet A is abnormal, then determine whether the upper-level distribution cabinet associated with it, that is, the second-level cabinet A, is abnormal. If so, then the third-level cabinet A and the third-level cabinet B should both be abnormal; if not, then determine whether the third-level cabinet B is operating abnormally.

[0103] The above method is helpful to quickly determine the abnormal location, and after determining the abnormal location, further analyze the obtained information to determine the specific type of abnormal data. Combined with the above example, if it is determined that only the third-level cabinet A is abnormal, and the abnormal data is that the temperature and humidity exceed the set threshold, then the distribution cabinet corresponding to the third-level cabinet A should be inspected and maintained in time to adjust the temperature and humidity.

[0104] Combined with the fourth aspect, combined Figure 5 The method also includes:

[0105] S210, obtaining operating parameters corresponding to the power distribution cabinet, the operating parameters at least including: a temperature value, a current value, and a load switch state of the power distribution cabinet.

[0106] S220, determining the abnormality type based on all operating parameters.

[0107] S230, obtaining coding information of the power distribution cabinet.

[0108] S240, determining the target location information and the target alarm mechanism corresponding to the coded information based on a preset mapping relationship.

[0109] S250, controlling the target alarm mechanism to start, and returning abnormality type information and target location information.

[0110] In this embodiment, the operating parameters of the distribution cabinet during operation are obtained and the abnormal type information is analyzed and judged based on a preset judgment logic combined with multiple operating parameters. Then, the target position information of the distribution cabinet is determined according to the coding information of the distribution cabinet. The abnormal type information and the target position information are returned to prompt the staff of the specific location and specific abnormal type of the distribution cabinet with the abnormal operation, so as to facilitate rapid positioning, fault diagnosis and equipment maintenance.

[0111] By acquiring the temperature value, current value and parameters of each load switch status in the distribution cabinet, it is possible to determine whether each individual electrical component is abnormal, and the abnormal type can be determined by combining all abnormal electrical components through the preset judgment logic. Among them, the coding information of each distribution cabinet and the location information corresponding to each coding information are pre-stored in the construction power controller, and the mapping relationship between the coding information of the distribution cabinet and the alarm mechanism is also pre-stored. In this way, when the coding information is known, the location information and alarm mechanism corresponding to the distribution cabinet with the coding information can be determined through the mapping relationship. This facilitates rapid positioning and improves equipment maintenance efficiency.

[0112] Among them, the location information may include specific positioning information and / or room number. The alarm agency can be one of multiple alarm agencies connected to the cloud service platform, or it can be the administrator's mobile terminal. As a feasible method, the cloud service platform connects to multiple alarm agencies, and multiple alarm agencies match different codes according to set coding rules. Multiple alarm agencies correspond one-to-one with multiple distribution cabinets. By observing the code of the alarm agency that sounds the alarm, the abnormal distribution cabinet can be quickly determined.

[0113] refer to Figure 6 As shown, an exemplary abnormal type judgment logic is provided, for example, in Figure 6 The middle sensor includes a temperature sensor, which is used to measure the temperature of the power distribution cabinet during operation, and two temperature thresholds T1 and T2 are preset, and T1<T2.

[0114] When the detected temperature value T0<T1, it is within the normal temperature range.

[0115] When the temperature value T1≤T0<T2, it means that the temperature is high and the distribution cabinet may be overloaded.

[0116] When the detected temperature value T2≤T0, it means that the temperature is too high and a fire may occur in the distribution cabinet.

[0117] Combination Figure 6 According to the judgment logic shown, when the temperature is at a high level and any of the three-phase overcurrents occurs, a switch cabinet overload alarm may occur. If the operating parameters remain unchanged after the delay T time, the abnormality type can be determined as: switch cabinet overload state.

[0118] Combined with the above examples, refer to Figure 6 ,When the door limit switch of the distribution cabinet is in the open state, and the incoming line voltage is not low voltage, it can be determined that the abnormal type is : switch cabinet intrusion state.

[0119] Combined with the above examples, refer to Figure 6 ,When the door limit switch of the distribution cabinet is in the open state, and ,only when the voltage is low, the abnormal type can be determined as : ,the maintenance state of the switch cabinet.

[0120] Combined with the above examples, refer to Figure 6 When the circuit breaker is in the open state in the opening position, or the circuit breaker is in the closed state in the closing position, and the state remains unchanged after the delay T, when obtaining the voltage only, if the wire voltage is not low voltage, it can be determined that the abnormal type is: switch cabinet fault state.

The specific judgment logic can be added or the specific parameters can be modified according to actual needs, and are not limited here.
