Technical Field

[0001] The utility model relates to the technical field of electrical explosion-proof boxes, in particular to a real-time monitoring system for the performance of electrical explosion-proof boxes. Background Art

[0002] As a flammable and explosive substance, the safe use of natural gas has always attracted much attention. Especially in key facilities such as natural gas transmission stations, any negligence may lead to serious fire or explosion accidents.

[0003] In places such as natural gas transmission stations, some equipment with potential safety hazards need to be installed in electrical explosion-proof boxes, which involve a large number of electrical explosion-proof boxes in natural gas stations. Once equipment failure or explosion-proof performance failure occurs in these explosion-proof boxes, it may cause fire or explosion if it is not discovered in time. The electrical explosion-proof box is a confined space and cannot be effectively monitored by the monitoring equipment in the station. At present, in various natural gas stations, electrical explosion-proof boxes in explosion-proof areas are opened manually on a regular basis to check their internal conditions and ensure the explosion-proof performance of the electrical explosion-proof box. This regular unpacking and inspection method has high repetitiveness, heavy workload and low work efficiency. At the same time, the regular unpacking and inspection method has a lag, and it is difficult to judge whether the explosion-proof box is invalid, smoked or on fire in time. It not only increases safety hazards, but also brings huge challenges to the safe operation of the station. Utility Model Content

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] This utility model refers to Figure 1 .

[0033] The utility model provides a real-time monitoring system for the performance of an electrical explosion-proof box, comprising an electrical explosion-proof box, a monitoring host 4, a transfer device 5, and a station control server. A humidity sensor 1, a flame detector 2, and a smoke detector 3 are arranged in the electrical explosion-proof box. The humidity sensor 1, the flame detector 2, and the smoke detector 3 are respectively connected to the monitoring host 4 by signal, the monitoring host 4 is connected to the transfer device 5 by signal, and the transfer device 5 is connected to the station control server by signal.

[0034] principle:

[0035] The humidity sensor 1, the flame detector 2 and the smoke detector 3 can monitor the conditions in the electrical explosion-proof box in real time from the three aspects of humidity, smoke and flame, so as to timely discover abnormal conditions inside the explosion-proof box. The status data of the humidity sensor 1, the flame detector 2 and the smoke detector 3 are transmitted to the monitoring host 4; the monitoring host 4 can analyze the received status data of the humidity sensor 1, the flame detector 2 and the smoke detector 3, such as extracting abnormal data; it can predict potential safety risks; at the same time, it can help personnel understand the operating rules of the explosion-proof box and grasp its working status at any time, so that personnel can timely discover abnormal conditions inside the explosion-proof box. At the same time, the monitoring host 4 transmits all data to the station control server through the transfer device 5. Engineers and operators can retrieve the data of the station control server at any time without opening the box, which is convenient for checking the internal conditions of the explosion-proof box and timely judging whether the explosion-proof box is invalid, smoking or on fire.

[0036] Note: The monitoring host 4 and the station control server are existing technologies. When the monitoring host 4 extracts abnormal data, for example, the humidity sensor 1 detects that the humidity is greater than the manually set value, the flame detector 2 detects the flame, and the smoke detector 3 detects that the smoke concentration is greater than the manually set value; humidity is an important parameter. If there is moisture inside the explosion-proof box, it is easy to cause the insulation performance of the electrical equipment to decrease, thereby increasing the risk of fire or explosion. The above-mentioned analysis process of the monitoring host 4 extracting abnormal data is just a simple comparison of the data with the set value, which is a conventional method of the existing technology. The role of the station control server can be used only to store data for personnel to retrieve, without relying on the control method of the equipment.

[0037] By adopting the utility model, the humidity sensor 1, the flame detector 2 and the smoke detector 3 can respectively monitor the conditions in the electrical explosion-proof box in real time from the three aspects of humidity, smoke and flame, thereby realizing real-time monitoring of the interior of the electrical explosion-proof box; personnel retrieve data through the station control server and can check the internal conditions of the explosion-proof box without opening the box, and can promptly determine whether the explosion-proof box is invalid, smoking or on fire, thereby reducing workload and improving work efficiency; data analysis is performed by the monitoring host 4, so that abnormal conditions inside the explosion-proof box can be discovered in time, and potential safety risks can be predicted.

[0038] Furthermore, the station control server includes an engineer station 6 and an operator station 7, and the engineer station 6 and the operator station 7 are respectively connected to the transfer device 5 through signals.

[0039] Note: The engineer station 6 and the operator station 7 are websites. A website is a host that has a domain name or address on the Internet and provides certain network services. It is a space for storing files and uses a server as a carrier. It belongs to the prior art. The engineer station 6 and the operator station 7 independently obtain data from the monitoring host 4 in real time. The data may include the status data of the humidity sensor 1, the flame detector 2 and the smoke detector 3, and the analysis data of the monitoring host 4. The analysis data includes abnormal data extracted by the monitoring host 4 and trend data predicted by the monitoring host 4. Engineers and operators can access and search data through a browser, etc., so as to remotely retrieve the situation data in the electrical explosion-proof box.

[0040] It is convenient for engineers to remotely retrieve the situation data inside the electrical explosion-proof box through the engineer station 6 and the operator through the operator station 7, so as to support the internal situation inspection and maintenance of the explosion-proof box and the formulation of maintenance plans, avoid mutual interference between different personnel, and ensure the smoothness and timeliness of data retrieval.

[0041] Furthermore, the station control server also includes a history server 8, and the history server 8 is connected to the transfer device 5 via a signal.

[0042] The history server 8 can be used to independently obtain and store data from the monitoring host 4 in real time, so that personnel can trace the operation status of the electrical explosion-proof box; at the same time, it avoids the need for the engineer station 6 and the operator station 7 to store too much redundant data, ensuring the smoothness and timeliness of real-time data retrieval.

[0043] Furthermore, the history server 8 is an OPC server.

[0044] Note: OPC is a communication specification. You only need to write the OPC server program and OPC client program according to this specification to ensure that the OPC server can be accessed by the OPC client. The OPC server can read the data of the device, such as PLC, DCS, etc., so as not to affect the history server 8 to read the data from the monitoring host 4; the OPC server program can open the data on the network, and engineers and operators can read it remotely through any OPC client program.

[0045] It is convenient for engineers and operators to trace the operation status of the electrical explosion-proof box and read it remotely, which is easy to operate and does not affect the history server 8 reading the data from the monitoring host 4.

[0046] Furthermore, the transfer device 5 is a switch.

[0047] It is convenient to transfer the data of the monitoring host 4 to the engineer station 6, the operator station 7 and the history server 8, and the operation is convenient.

[0048] Furthermore, the monitoring host 4 is also connected to an audible and visual alarm 9 via a signal.

[0049] When the monitoring host 4 detects an abnormal situation from any aspect of humidity, smoke and flame, the sound and light alarm 9 can be activated to facilitate personnel to promptly discover the abnormal situation inside the explosion-proof box.

[0050] Furthermore, the humidity sensor 1 is a resistive lithium chloride humidity sensor 1.

[0051] It has high precision, simple structure, low cost, and can meet the explosion-proof requirements in flammable and explosive occasions.

[0052] Furthermore, the smoke detector 3 is an ionization smoke sensor.

[0053] It has stable operation and high reliability, and its performance is far superior to gas-sensitive resistor fire alarms. It also meets the explosion-proof requirements of flammable and explosive occasions and achieves fire prevention by monitoring the concentration of smoke.

[0054] Furthermore, the flame detector 2 is a point-type red-ultraviolet photoelectric sensor.

[0055] Equipped with high-precision data processing chips to meet the explosion-proof requirements of flammable and explosive occasions; it is small in size, light in weight, easy to install, reduces the response time of the detector, has high accuracy, improves the flame detection capability and prevents false alarms.

[0056] Furthermore, the humidity sensor 1, the flame detector 2 and the smoke detector 3 are respectively connected to the monitoring host 4 via signal cables, and a sealing structure is provided between the signal cables and the electrical explosion-proof box.

[0057] Note: The sealing structure may be an elastic sealing ring. In addition, the cable sealing structure is a prior art.

[0058] This is convenient for ensuring the reliability of signal transmission, so that the monitoring host 4 can obtain the status data of the humidity sensor 1, the flame detector 2 and the smoke detector 3 in real time.

[0059] Note: The monitoring host 4 and the transfer device 5 can be connected via a network cable, and the transfer device 5 and the station control server can be connected via a network cable.
