Residual current electrical fire monitoring system principle and installation precautions

Tag: Security detector Alarm Controller for current transformer 1 Prevention of electrical fire In order to prevent and reduce electric fire, the insulation status of 220/380 V power supply line should be monitored online, and the electric fire monitoring system can be used for leakage detection and alarm. Electrical circuit or electrical equipment once the leakage and exceed the rated value, the alarm immediately issued a sound and light alarm

Java deserialization, object injection can cause code execution vulnerability

Java deserialization, object injection can cause code execution vulnerability 0x01 PrincipleJava deserialization results in the same principle as PHP deserialization, because user input can control the input objects. If the server program does not verify the user-controllable serialization code but is used for deserialization, and the program runs some dangerous logic (such as eval and login verification ), this will trigger unexpected vulnerabilities. In fact, this is not a new issue. For detai

Use Dom to generate xml files

The parser establishes tree structure data corresponding to the XML structure in the memory, so that the application can conveniently obtain data in the XML file. JAXP also provides an API for creating an XML file using the tree structure data in the memory, that is, using the document object obtained by the parser to create a new XML file.1. Transformer objectWe already know that the parse method of the parser encapsulates the parsed XML file into a

Basic hardware concepts-Analog Electronic Circuits

In electronic circuits, power supply, amplification, oscillation, and Modulation circuits are called Analog Electronic Circuits because they process and process continuously changing analog signals. 1. Feedback Feedback refers to sending output changes to the input end in some way as part of the input. If the return part and the original input part are subtracted, It is negative feedback. 2. Coupling An amplifier usually has several levels, and the association between levels is called coupling.

Therefore, the power supply also has high-voltage and high-power components, as well as small-power components that process low voltage and control signals. The power conversion process is AC input → EMI filtering circuit → rectification circuit → Power Factor Correction Circuit (active or passive PFC) → power level primary side (High Voltage Side) switching circuit to p

standard network interface cards (NICs), in most cases, Gigabit Ethernet cards. The hardware initiator is an ISCSI HBA (or TCP Offload engine (TOE) card), which is essentially a dedicated Ethernet card on which the SCSI ASIC can offload all work (TCP and SCSI commands) from within the system CPU. ISCSI HBAs can be purchased from many vendors, including Adaptec, Alacritech, Intel, and QLogic. 8. ISCSI Target The iSCSI target is the "server" component of the iSCSI network. It is

difference, resulting in thermal stress and thermal shock. The component is subjected to thermal-mechanical stress. When the temperature difference is too large, different parts of the component may produce stress cracks. Early component failure. This requires that the power element should work in a relatively stable operating temperature range to reduce the sharp changes in the temperature, so as to eliminate the impact of thermal stress and ensure long-term reliable operation of the element.

If you use JAXP 1.1, you do not need to download Apache Crimson and compile and run the above example (AddRecord. java ). The latest JAXP 1.2 EA (Early Access) is changed to a new one. Apache Xalan and Apache Xerces, which have better performance, are used as the XSLT processor and XML parser respectively, and cannot directly support Apache Crimson, therefore, if your developmen
