Description

Technical Field

[0001] The present invention relates to the technical field of power construction, and specifically to a multi-device linkage cable channel anti-external damage monitoring system and a monitoring method. Background Art

[0002] With the continuous development of the power industry, urban overhead line power transmission is being replaced by underground high-voltage cables. An underground cable refers to a cable that is usually buried underground compared with common overhead lines. A cable is a conductor used to transmit power or information from one place to another. Since the value of the cable is relatively high, in order to prevent the cable channel from being damaged externally, it is necessary to monitor the cable in real time.

[0003] According to a cable anti-external damage monitoring system disclosed in Chinese Patent Application Publication No. CN117470362A, it includes a sensing optical fiber laid along the cable, a transmitting device for emitting laser pulses to the sensing optical fiber, and a processing device for monitoring the vibration condition of the sensing optical fiber. The cable anti-external damage monitoring system further includes a plurality of alarm devices arranged in sequence along the sensing optical fiber; the alarm device includes a pile body that can be installed on the ground, and a camera, an alarm, and a controller are arranged on the pile body. A power supply is arranged at the upper end of the pile body, and the power supply is used to supply power to the camera, the alarm, and the controller. The present invention provides a cable anti-external damage monitoring system. When the sensing optical fiber vibrates, the camera takes pictures of the person who damages the cable and gives a warning to the person; However, for the above monitoring system, it is powered by solar energy. When encountering extremely bad weather, it may cause the monitoring system to break down. And when a sensor at a certain position is damaged, there may be no alarm, and it is difficult for the nearby security personnel to quickly reach the externally damaged place to prevent the external damage from continuing, and the efficiency of external damage monitoring is relatively low.

A cable is provided at the monitoring location of the on-site equipment, and the cable is used for being monitored by the monitored equipment; The on-site equipment includes a monitor switch. The receiving end of the monitor switch is electrically connected to the output end of the local area ring network. The output end of the monitor switch is electrically connected to a monitoring gateway. The output end of the monitoring gateway is electrically connected to a monitoring device. A first monitoring node and a second monitoring node are sequentially arranged on the cable; The output end of the monitoring device is electrically connected to the receiving end of the first monitoring node and the receiving end of the second monitoring node. The output end of the first monitoring node is electrically connected to a first vibration sensor and a first temperature sensor. The output end of the second monitoring node is electrically connected to a second vibration sensor and a second temperature sensor. The output end of the second vibration sensor is electrically connected to the receiving end of the first monitoring node. The output end of the first vibration sensor is electrically connected to the receiving end of the second monitoring node.

[0006] As a preferred solution of the present invention, a power-off control switch is fixedly installed inside the monitoring device. The output end of the power-off control switch is electrically connected to a built-in power supply. The output end of the built-in power supply is electrically connected to a presence sensor and a monitoring probe.

[0007] As a preferred solution of the present invention, the host computer software is used for data processing, the review software is used for data review, and the server is used for data storage.

[0008] As a preferred solution of the present invention, the monitor switch is used to connect the monitoring gateway and the local area ring network. The monitoring gateway is used to transmit the data inside the monitoring device. The local area ring network is used to transmit the data transmitted by the monitoring gateway.

[0009] As a preferred solution of the present invention, the first monitoring node and the second monitoring node are used to collect data at the first vibration sensor, the second vibration sensor, the first temperature sensor, and the second temperature sensor. The first vibration sensor and the second vibration sensor are used to convert the change of the measured mechanical vibration parameter into the change of an electrical parameter signal. The first temperature sensor and the second temperature sensor are used to measure the change of temperature.

[0010] As a preferred solution of the present invention, the power-off control switch is used to control the power transmission of the built-in power supply. The built-in power supply is used to supply power to the human presence sensor and the monitoring probe. The human presence sensor is used to sense whether there is anyone nearby, and the monitoring probe is used for monitoring the monitoring point.

[0011] As a preferred solution of the present invention, the specific method for the cable to be used for external damage monitoring is as follows: First, a first vibration sensor and a first temperature sensor are used to monitor a section of the cable. The first vibration sensor converts the change in the vibration parameter of the monitored cable section into a change in the electrical parameter signal. The first temperature sensor monitors the change in the temperature of the cable section. The first monitoring node collects and pre-stores the data at the first vibration sensor and the first temperature sensor. Then, a second vibration sensor and a second temperature sensor are used to monitor the next section of the cable. The second vibration sensor converts the change in the vibration parameter of the monitored cable section into a change in the electrical parameter signal. The second temperature sensor monitors the change in the temperature of the cable section. The second monitoring node collects and pre-stores the data at the first vibration sensor and the first temperature sensor. At this time, the first monitoring node and the second monitoring node transmit the collected data to the monitoring device. The monitoring device transmits the data to the monitoring gateway. The monitoring switch provides an exclusive electrical signal path for the monitoring gateway and the local area ring network connected to the switch, so that the data in the monitoring gateway can be transmitted to the local area ring network. The local area ring network transmits the data to the server. The server stores the data. The upper computer software analyzes and compares the data stored in the server to obtain the vibration information and temperature change information of the cable section, and determines the usage status of the cable section. After the upper computer software makes a comparison, the data is transmitted to the review software for secondary comparison, so as to determine the information of the monitored cable section. When the cable section is externally damaged, the data analyzed by the server in real time will be abnormal. Then, the review software is used for secondary analysis. When the data analyzed by the review software is still abnormal, the server will perform an alarm operation through the alarm. The nearby security personnel can quickly reach the externally damaged area to prevent the external damage from continuing and reduce the loss caused by the external damage of the cable; When the first vibration sensor and the first temperature sensor at the first monitoring node are damaged, the first monitoring node cannot monitor the cable before the first vibration sensor and the first temperature sensor are repaired. Since the cable is an integral whole, when one part of the cable vibrates, a slight vibration will also occur at another part of the cable. The second vibration sensor will detect vibrations of different amplitudes. At this time, both the first monitoring node and the second monitoring node can collect the data monitored by the second vibration sensor and transmit the data to the monitoring device. The monitoring device transmits the data to the monitoring gateway. Through the monitor switch, an exclusive electrical signal path is provided for the monitoring gateway and the local area ring network accessing the switch, enabling the data in the monitoring gateway to be transmitted to the local area ring network. The local area ring network transmits the data to the server, and the server stores the data. The upper computer software compares the vibration variables collected by the second monitoring node. When the vibration variable is greater than the preset value, the server will perform an alarm operation through the alarm. The nearby security personnel can quickly reach the location of the external damage, prevent the external damage from continuing, and reduce the loss caused by the external damage to the cable. When the first monitoring node and the second monitoring node are powered off, the monitoring device is in a blind state at this time. The server directly alarms through the alarm. The monitoring device starts the built-in power supply through the power-off control switch. The built-in power supply transmits electrical energy to the presence sensor and the monitoring probe for real-time monitoring operations. Real-time monitoring of the cable can be completed before the maintenance personnel arrive at the repair location, avoiding the phenomenon of the cable being externally damaged during a power outage.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, the built-in power supply is started through the power-off control switch. The built-in power supply transmits electrical energy to the presence sensor and the monitoring probe for real-time monitoring operations. Real-time monitoring of the cable can be completed before the maintenance personnel arrive at the repair location, avoiding the phenomenon of the cable being externally damaged during a power outage. When one part of the cable vibrates, a slight vibration will also occur at another part of the cable. The second vibration sensor will detect vibrations of different amplitudes. The upper computer software compares the vibration variables collected by the second monitoring node. When the vibration variable is greater than the preset value, the server will perform an alarm operation through the alarm. The nearby security personnel can quickly reach the location of the external damage, prevent the external damage from continuing, and reduce the loss caused by the external damage to the cable.

A first monitoring node 209 and a second monitoring node 210 are successively arranged on the cable 4. The monitor switch 201 is used to connect the monitoring gateway 202 and the local area ring network 104. The monitoring gateway 202 is used to transmit the data inside the monitoring device 203. The local area ring network 104 is used to transmit the data transmitted by the monitoring gateway 202; The monitoring gateway 202 is a kind of protocol converter.

The first temperature sensor 212 and the second temperature sensor 208 are used to measure the change of temperature; The first vibration sensor 211 and the second vibration sensor 213 are an inductive sensor. According to the relative mechanical reception principle of the inductive sensor, the first vibration sensor 211 and the second vibration sensor 213 can convert the change of the measured mechanical vibration parameter into the change of the electrical parameter signal.

The monitoring probe 205 is used for monitoring at the monitoring point; The presence sensor 206 is also called a non-contact proximity sensor and is an ideal electronic switch quantity sensor. When the human body approaches the sensing area of the sensor, the switch can issue an electrical instruction quickly without contact, pressure or spark, and accurately reflect the position and movement of the human body. Thus, when the presence sensor 206 is turned on, it can monitor whether there is personnel flow in the cable channel in real time; The monitoring probe 205 is a monitoring camera, mainly used for a series of security activities such as security inspection, real-time control, investigation and evidence collection, so as to complete the real-time monitoring of the cable channel and prevent non-operation and maintenance personnel from entering.

[0020] The present application also discloses a method for monitoring the prevention of external damage to a cable channel with multi-device linkage: A first vibration sensor 211 and a first temperature sensor 212 are used to monitor a section of the cable 4. The first vibration sensor 211 converts the change in the vibration parameter of the monitored section of the cable 4 into a change in an electrical parameter signal, and the first temperature sensor 212 monitors the change in the temperature of the monitored section of the cable 4. The first monitoring node 209 collects and pre-stores the data from the first vibration sensor 211 and the first temperature sensor 212. Then, a second vibration sensor 213 and a second temperature sensor 208 are used to monitor the next section of the cable 4. The second vibration sensor 213 converts the change in the vibration parameter of the monitored section of the cable 4 into a change in an electrical parameter signal, and the second temperature sensor 208 monitors the change in the temperature of the monitored section of the cable 4. The second monitoring node 210 collects and pre-stores the data from the first vibration sensor 211 and the first temperature sensor 212. At this time, the first monitoring node 209 and the second monitoring node 210 transmit the collected data to the monitoring device 203. The monitoring device 203 transmits the data to the monitoring gateway 202. The monitor switch 201 provides an exclusive electrical signal path for the monitoring gateway 202 and the local area ring network 104 connected to the switch, so that the data in the monitoring gateway 202 can be transmitted to the local area ring network 104. The local area ring network 104 transmits the data to the server 101. The server 101 stores the data. The upper computer software 102 analyzes and compares the data stored inside the server 101 to obtain the vibration information and temperature change information of the cable 4, and determines the usage status of the cable 4. After the upper computer software 102 makes a comparison, the data is then transmitted to the review software 103 for a second comparison, so as to determine the information of the monitored section of the cable 4. When the cable 4 is damaged externally, the data analyzed in real time by the server 101 will be abnormal, and then a second analysis is performed by the review software 103. When the data analyzed by the review software 103 is still abnormal, the nearby security personnel can quickly reach the damaged area and prevent the external damage from continuing, reducing the loss caused by the external damage to the cable 4; After the first vibration sensor 211 and the first temperature sensor 212 at the first monitoring node 209 are damaged, the first monitoring node 209 cannot monitor the cable 4 before the first vibration sensor 211 and the first temperature sensor 212 are repaired. Since the cable 4 is an integral unit, when one part of the cable 4 vibrates, a slight vibration will also occur at another part of the cable 4. The second vibration sensor 213 will detect vibrations of different amplitudes. At this time, both the first monitoring node 209 and the second monitoring node 210 can collect the data monitored by the second vibration sensor 213 and transmit the data to the monitoring device 203. The monitoring device 203 transmits the data to the monitoring gateway 202. The monitoring switch 201 provides an exclusive electrical signal path for the monitoring gateway 202 and the local area ring network 104 connected to the switch, enabling the data in the monitoring gateway 202 to be transmitted to the local area ring network 104. The local area ring network 104 transmits the data to the server 101. The server 101 stores the data, and the upper computer software 102 compares the vibration variables collected by the second monitoring node 210. When the vibration variable is greater than the preset value, the server 101 will perform an alarm operation through the alarm 3. The nearby security personnel can quickly arrive at the external damage location and prevent the external damage from continuing, reducing the loss caused by the external damage to the cable 4; When the first monitoring node 209 and the second monitoring node 210 are powered off, the monitoring device 203 is in a blind state at this time. The server 101 directly alarms through the alarm 3. The monitoring device 203 starts the built-in power supply 207 through the power-off control switch 204. The built-in power supply 207 transmits electrical energy to the human presence sensor 206 and the monitoring probe 205 for real-time monitoring operations, and can complete the real-time monitoring of the cable 4 before the operation and maintenance personnel arrive at the repair location, avoiding the phenomenon of external damage to the cable 4 during a power outage.

[0021] When the multi-device linkage cable channel anti-external damage monitoring method of this solution is working, first, a first vibration sensor 211 and a first temperature sensor 212 are used to monitor a location of the cable 4. The first vibration sensor 211 converts the change in the vibration parameter of the monitored cable 4 into a change in the electrical parameter signal, and the first temperature sensor 212 monitors the temperature change of the cable 4. The first monitoring node 209 collects and pre-stores the data from the first vibration sensor 211 and the first temperature sensor 212.

The second monitoring node 210 collects and pre-stores the data from the first vibration sensor 211 and the first temperature sensor 212. At this time, the first monitoring node 209 and the second monitoring node 210 transmit the collected data to the monitoring device 203. The monitoring device 203 transmits the data to the monitoring gateway 202. The monitoring switch 201 provides an exclusive electrical signal path for the monitoring gateway 202 and the local area ring network 104 connected to the switch, so that the data in the monitoring gateway 202 can be transmitted to the local area ring network 104.

Since the cable 4 is an integral unit, when one part of the cable 4 vibrates, a slight vibration will also occur at another part of the cable 4. The second vibration sensor 213 will detect vibrations of different amplitudes. At this time, both the first monitoring node 209 and the second monitoring node 210 can collect the data monitored by the second vibration sensor 213 and transmit the data to the monitoring device 203.

7. A multi-device linkage cable channel anti-external damage monitoring method, using a multi-device linkage cable channel anti-external damage monitoring system as claimed in any one of claims 2 to 6, characterized in that: The specific method of using the cable (4) for external damage prevention monitoring is: First, a point of the cable line (4) is monitored by a first vibration sensor (211) and a first temperature sensor (212); the first vibration sensor (211) converts changes in vibration parameters at the cable line (4) into changes in electrical parameter signals; the first temperature sensor (212) monitors changes in temperature at the cable line (4); the first monitoring node (209) collects and pre-stores data at the first vibration sensor (211) and the first temperature sensor (212); and then the second vibration sensor (213) and the second temperature sensor ( The second monitoring node (208) monitors the next location of the cable line (4), the second vibration sensor (213) converts the change of the vibration parameter at the monitored cable line (4) into the change of the electrical parameter signal, the second temperature sensor (208) monitors the change of the temperature at the cable line (4), the second monitoring node (210) collects and pre-stores the data at the first vibration sensor (211) and the first temperature sensor (212), and the first monitoring node (209) and the second monitoring node (210) transmit the collected data to the monitoring device (203), and the monitoring device The device (203) transmits the data to the monitoring gateway (202), and provides an exclusive electrical signal path for the monitoring gateway (202) and the local ring network (104) connected to the switch through the monitor switch (201), so that the data in the monitoring gateway (202) can be transmitted to the local ring network (104), and the local ring network (104) transmits the data to the server (101), and the server (101) stores the data. The upper computer software (102) analyzes and compares the data stored in the server (101) to obtain the vibration at the cable line (4). The information and temperature change information are used to determine the use status of the cable (4). After the upper computer software (102) performs a comparison, the data is transmitted to the review software (103) for a secondary comparison, thereby determining the information of the cable (4) monitoring location. When the cable (4) is damaged, the data analyzed in real time by the server (101) will be abnormal, and the review software (103) will perform a secondary analysis. When the data analyzed by the review software (103) is still abnormal, the server (101) will perform an alarm operation through the alarm (3) to prevent the cable (4) from being damaged. When the first vibration sensor (211) and the first temperature sensor (212) at the first monitoring node (209) are damaged, before the first vibration sensor (211) and the first temperature sensor (212) are repaired, the first monitoring node (209) cannot monitor the cable (4). Since the cable (4) is a whole, when one part of the cable (4) vibrates, another part of the cable (4) will also vibrate slightly, and the second vibration sensor (213) will monitor vibrations of different amplitudes. At this time, the first monitoring node (209) and the second monitoring node (210) can both collect data monitored by the second vibration sensor (213) and transmit the data to the monitoring device (203). The monitoring device (203) transmits the data to the monitoring gateway (202), and provides an exclusive electrical signal path for the monitoring gateway (202) and the local ring network (104) connected to the switch through the monitor switch (201), so that the data in the monitoring gateway (202) can be transmitted to the local ring network (104), and the local ring network (104) transmits the data to the server (101), and the server (101) stores the data. The upper computer software (102) compares the vibration variable collected by the second monitoring node (210). When the vibration variable is greater than a preset value, the server (101) will perform an alarm operation through the alarm (3), thereby reducing the loss caused by the cable (4) being damaged externally; When the power is cut off at the first monitoring node (209) and the second monitoring node (210), the monitoring device (203) is in a blind state, the server (101) directly issues an alarm through the alarm (3), the monitoring device (203) starts the built-in power supply (207) through the power-off control switch (204), and the built-in power supply (207) transmits electric energy to the person at the sensor (206) and the monitoring probe (205) to perform real-time monitoring operations. Before the operation and maintenance personnel arrive at the maintenance site, real-time monitoring of the cable line (4) can be completed, thereby preventing the cable line (4) from being damaged when the power is cut off.
