Features and applications:

the internal cable joints of ring main unit / frequency conversion cabinet / high voltage cabinet / power cabinet are easy to heat up due to various reasons, resulting in temperature rise, which is easy to cause oxidation problems, leading to a substantial reduction in the actual service life of the cable, and may also produce a series of hazards such as explosion, insulation breakdown, and even a large area of power failure, which will eventually affect the whole power supplyNetwork operation security.The fluorescent optical fiber temperature measuring device independently developed by Fuzhou Beijing kaidexing can detect the temperature of cable joints in ring main unit / frequency conversion cabinet / high voltage cabinet / power cabinet.The temperature measurement system of ring main unit / frequency conversion cabinet / high voltage cabinet / power cabinet developed based on the principle of fluorescence optical fiber temperature measurement can measure various joint temperatures. It can also be confirmed by several customer cases that the optical fiber temperature measurement system can be used in the temperature detection of cable joints of ring main unit / frequency conversion cabinet / high voltage cabinet / power cabinet.

The fluorescent optical fiber temperature measurement system for cable joints of ring main unit / frequency conversion cabinet / high voltage cabinet / power cabinet is intrinsically safe, strong electromagnetic interference resistance, good electrical insulation, stable performance, corrosion resistance and long service life; it has high temperature measurement accuracy, wide range of temperature measurement range and flexible configuration of temperature measurement channels;It has the advantages of simple installation, flexible networking, standardized data transmission, high cost performance and stable quality; it is the preferred product for temperature monitoring such as power ring network cabinet / frequency conversion cabinet / high voltage cabinet / power cabinet cable joint, insulation plug and elbow head.

The optical fiber temperature measurement system of cable joint of ring main unit / frequency conversion cabinet / high voltage cabinet / power cabinet adopts fluorescent optical fiber temperature measurement device. The sensor probe of the device has no metal material, and adopts imported quartz optical fiber, which has complete electrical insulation, is not affected by high voltage and strong electromagnetic field, and is resistant to chemical corrosion and pollution. Moreover, the temperature measurement of the temperature measuring probe is increased through the processing of our companyIt can measure the temperature of the outer wall of the cable joint with fast response, simple installation and high temperature resistance.At the same time, the system also provides remote transmission, which is convenient for customers to install communication software at any computer end and remote monitoring.

System structure: 

product technical parameters:

The network topology structure of optical fiber temperature measurement system is composed of master station, switch, repeater, transmitter and fluorescent optical fiber probe.The main station of the system includes the main station hardware equipment (local server, client workstation, switch, etc.) and the master station software system (operating system, fluorescent optical fiber temperature measurement software, master station application management system).

The data transmission channel between the background system and the acquisition equipment is the uplink channel, and the communication mode is wireless GPRS or Ethernet.

Ethernet or GPRS / CDMA communication mode is adopted between switch and repeater, and each switch supports 24

10 / 100Mbps adaptive Ethernet port.

RS485 or wireless 433M communication mode is adopted between the repeater and the transmitter. The temperature measurement system in the background master station system: all data acquisition, management and temperature display are completed by the master station application software. The system mainly realizes the data acquisition and monitoring of the measured temperature.

The uplink communication channel of the switch can adopt Ethernet mode.

Ethernet or GPRS / CDMA communication mode is adopted for the downlink communication of the switch.The uplink communication of repeater adopts Ethernet or GPRS / CDMA communication mode.RS485 or GPRS / CDMA communication mode is adopted for the downlink communication of the repeater.

The transmitter integrates multi-channel fluorescent optical fiber to provide external 485 communication and anti-interference design.

The application function of optical fiber temperature measurement system can set the data collection density according to the customer's demand. The system collects the data regularly according to the set parameters, and then displays in the form of table or drawing curve to achieve the purpose of real-time monitoring.Real time monitoring equipment working condition, real-time monitoring and recording cable joint temperature.

Remote web access function customers can download monitoring software from other computers and log in to access the temperature data on the server.

According to the requirements of SMS sending, the system will send the following SMS: alarm SMS notification, when the temperature of cable joint exceeds the set alarm value, SMS will be sent to inform the staff.

Abnormal SMS notification when the transmitter is abnormal, it will send SMS to inform the staff.

The function of data security protection and backup: it has three-level security mechanisms: operating system level, database level and application software level.

Operating system level: set different permissions and passwords in the network, non system administrators can not operate the server and database, and ensure the security and relative independence of the system through routing, firewall and other settings.

Database level: in the database, the demanders with different permissions and corresponding passwords are set to ensure that illegal demanders can not use data, and different demanders can not use data by skipping levels.

Application software level: provide strict user login verification, authority control and perfect management of event log and operation record.System authority control includes function authority control and data access control.

Function permission control:

the function permission control system carries out permission management from three dimensions: control object, object operation and operator. On this basis, it provides authorization methods for control object group, operation group and operator role. The accuracy of authority control can be down to the specific control object and operator. The system determines the operation authority of login personnel according to three dimensions.

The control objects of the system include system level nodes, terminal equipment, etc. each control object has corresponding operation. Each authorization includes three parts: a control object group, an operation or operation group, and an operator role. For the sake of simple and convenient authority management, the system provides the inheritance of control object group permissions.

The system provides hierarchical authorization mechanism, which enables the system to have the ability of distributed authority management, and solves the problem of too complex authority management.

Data access rights: the data access authority control mechanism adopts the security audit mechanism provided by the database, provides data access user control, and provides log audit for all data operations.

The original database only has the query function, and the application only operates on the application database to ensure the data security.The system can store the power data with time scale and various analysis application calculation data, and the storage time is more than 2 years. In addition, the system has a powerful backup subsystem.

There are detailed operation log records for all manual intervention data.The design of the system ensures high fault tolerance. The database has three levels of data rationality test, including field level, record level and database level, to ensure the storage of illegal data.

We conduct quality inspections on raw materials to ensure the reliability and stability of the mechanical product manufacturing process.
