At present, there are products from different manufacturers that cannot be interconnected, and it is impossible to view the equipment operating parameters in a timely and convenient manner on site. Utility Model Content
[0003] The utility model provides a mine flameproof and intrinsically safe electric power monitoring substation, which is used to solve the defects in the prior art.
[0004] The utility model is realized through the following technical solutions:
[0005] A mine-use explosion-proof and intrinsically safe power monitoring substation comprises a shell, which is divided into a main intrinsically safe chamber and an uninterruptible power supply chamber by a partition. A network management machine with multiple data interfaces, a high-definition display screen for signal transmission with the network management machine, a digital signal acquisition unit, a ring network switch and an analog signal acquisition unit are fixedly arranged in the main intrinsically safe chamber; a transparent observation window is inlaid on the shell, and the observation window is located above the high-definition display screen.
[0006] In this application, the shell can protect the inside of the shell, and the observation window facilitates the observation of the high-definition display screen, which makes it convenient for the staff to observe the information fed back on the high-definition display screen and the observation window can protect the high-definition display screen. The digital signal acquisition unit can uniformly convert and store the digital signals of the acquisition devices such as RS485, RS232, CAN, etc. for all devices that need to be monitored, and then transmit them to the network management machine through the Ethernet interface. At the same time, if there is a control signal, the operation of the required control device is also realized through the digital signal acquisition unit. The analog signal acquisition unit can collect analog signals for all devices with analog signals through shielded twisted pair transmission, such as collecting analog signals detected and converted by gas sensors, temperature sensors, smoke, and fog sensors. After the analog signal acquisition unit receives the signal, it converts the digital quantity, and then transmits it to the network management machine through Ethernet for packaging. The network management machine is the core of the product, which has a database storage conversion system inside, with high integration and strong versatility. Its database has good openness and interconnection functions. At the same time, the hardware design of the network management machine has multiple data interface modes to ensure the compatibility of different data interfaces of the system. For example, the IEC61850 communication line that complies with the power regulations can be directly connected to the network management machine. Through configuration, its data can be directly collected and packaged for storage and forwarding. This can realize the intercommunication of products from different manufacturers.
[0007] Preferably, the observation window is located at the upper part of the shell and arranged obliquely upward. The oblique upward arrangement of the observation window can further facilitate observation by the staff.
[0008] Preferably, the observation window is explosion-proof glass and a cover is provided above the observation window, one side of the cover is hingedly connected to the housing. The cover can protect the observation window, and when observation is required, the cover only needs to be flipped open.
[0009] Preferably, a digital signal intrinsically safe isolator is fixedly installed in the main intrinsically safe cavity, and the digital signal intrinsically safe isolator is located below the network management machine, the digital signal acquisition unit and the analog signal acquisition unit. The digital signal intrinsically safe isolator can effectively isolate the field loop signal of the underground dangerous area from the loop signal of the safe area to ensure the reliability and safety of the system.
[0010] Preferably, a battery and a battery management system component are arranged in the uninterruptible power supply cavity, so as to supply power to the device.
[0011] Preferably, a cable introduction plug is provided on the upper portion of the shell, so as to realize functions such as communication, detection and control with external equipment through different cables.
