Description

Technical Field

[0001] The present invention relates to the field of control technology, and in particular to a remote detection system and a detection method for a control cabinet. Background Art

[0002] With the continuous development of industrial automation and informatization, control cabinets are an important part of industrial production, and the operating status of their internal equipment is directly related to the stability and safety of the entire production process. However, the traditional control cabinet detection method mainly relies on manual inspection, which is not only inefficient, but also unable to monitor the operating status of the equipment in the control cabinet in real time. Once a fault occurs, it is often difficult to detect and handle it in time, which has a serious impact on production.

[0003] However, there are still some problems with the existing remote detection systems. First, the existing remote detection systems can usually only monitor a single type of data, such as temperature or current and voltage, and cannot fully reflect the operating status of the equipment in the control cabinet. Secondly, the existing remote detection systems often use wireless transmission methods during data transmission. When the electromagnetic waves carried by wireless communication are blocked and interfered with, data transmission becomes unstable. In addition, when the circuit of the equipment in the control cabinet is in a power-off state, that is, the power is off in the area, it also means that the switches or routers of the wired network nodes have no power. The existing remote detection systems often cannot work normally and cannot send power-off signals to users in time. Summary of the invention

[0014] In some embodiments, a slide rail is disposed on the bottom wall of the first shell, and a top mounting end of the slide rail is fixedly connected to the bottom wall of the first shell.

[0015] In some embodiments, the detection component includes a temperature sensor, a current and voltage sensor, a humidity sensor, a vibration sensor, and a smoke detector. The temperature sensor, the current and voltage sensor, the humidity sensor, the vibration sensor, and the smoke detector are respectively arranged in a plurality of the first chambers. The mounting ends of the temperature sensor, the current and voltage sensor, the humidity sensor, the vibration sensor, and the smoke detector are respectively fixedly connected to the corresponding inner wall of the first chamber. The bottom detection ends of the temperature sensor, the humidity sensor, and the smoke detector respectively penetrate the bottom wall of the first shell and extend downward into the control cabinet.

[0016] The current and voltage sensor is electrically connected to the device circuit in the control cabinet through an electric wire that passes through the bottom of the first shell.

[0017] In some embodiments, the detection component also includes a night vision camera, which is disposed at the bottom of the first shell, and the top mounting end of the night vision camera is fixedly connected to the bottom sliding end of the slide rail.

[0018] In some embodiments, the night vision camera, temperature sensor, current and voltage sensor, humidity sensor, vibration sensor, and smoke detector are all electrically connected to the data processor, and the reserve battery is electrically connected to the night vision camera, temperature sensor, current and voltage sensor, humidity sensor, vibration sensor, smoke detector, data processor, and data storage device, respectively.

[0019] In a second aspect, the present invention provides a remote detection method for a control cabinet, comprising the following steps:

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] As mentioned in the background technology, the existing remote detection system can usually only monitor a single type of data, such as temperature or current and voltage, and cannot fully reflect the operating status of the equipment in the control cabinet. Secondly, the existing remote detection system often uses wireless transmission during data transmission. When the electromagnetic waves of the wireless communication carrier are blocked and interfered, the data transmission becomes unstable. In addition, when the circuit of the equipment in the control cabinet is in a power-off state, that is, the power is off in the area, it also means that the switches or routers of the wired network nodes have no power. The existing remote detection system often cannot work normally and cannot send a power-off signal to the user in time.

[0035] In order to improve the above problems, the present application proposes a remote detection system and detection method for a control cabinet. By setting a variety of sensors inside and outside the control cabinet, such as temperature sensors, current and voltage sensors, humidity sensors, vibration sensors and smoke detectors, etc., it is possible to monitor the operating status of the equipment in the control cabinet in real time and comprehensively, including multiple parameters such as temperature, current and voltage, humidity, vibration and smoke. This helps to timely discover potential problems and abnormal conditions and improve the safety and reliability of the equipment. Compared with wireless transmission, wired networks are used for data transmission. Wired networks are more stable and reliable, less susceptible to environmental interference, and ensure accurate data transmission. When the circuit of the equipment in the control cabinet is in a power-off state, the reserve battery can power key components such as night vision cameras, sensors, data processors and data storage devices, so that the system can continue to work without an external power supply. This design ensures that in an emergency, the system can still operate normally and send a power-off signal to the user, thereby improving the reliability and safety of the system. The inner wall of the first shell and the inner wall of the switch door are both provided with a fireproof layer. This design can effectively prevent the occurrence of fire and protect the safety of the equipment inside the control cabinet. This method greatly improves the detection efficiency, reduces labor costs, and also improves the stability and safety of the production process.
