Description

Technical Field

[0001] The utility model relates to the field of cable environment monitoring, in particular to a device for real-time monitoring of cable breakage status. Background Art

[0002] As the existing railway cables are laid longer and longer, the maintenance workload and difficulty of the cables are also increasing. At present, in the daily management and maintenance of cables, the most feared situation is the sudden cable breakage. Because when the cable breaks accidentally, there is currently no special instrument and equipment to monitor the cable breakage. The only way to detect abnormalities is through the monitoring of the main equipment by the centralized monitoring system. However, this method takes at least a few seconds to tens of seconds to detect equipment problems. From detecting equipment problems to sending people to the site to find out the cause, it takes at least tens of minutes, which can easily cause driving delays or even affect driving safety.

[0003] Therefore, in order to solve the difficulties caused by the above monitoring methods, such as difficulty in maintaining cables far away from the station and difficulty in troubleshooting, this patent proposes a collection device for real-time monitoring of the cable break status. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for real-time monitoring of the cable breakage status includes a single-chip processor, wherein the single-chip processor is connected to a monitoring circuit, a collection circuit, and an alarm circuit;

[0007] The monitoring circuit performs real-time detection of the cable under test through an optical coupler. When the optical coupler detects that the broken state of the cable under test has changed, the acquisition circuit acquires the state information of the cable under test through an operational amplifier to determine whether the cable is really broken. When it is determined that the cable is broken, the single-chip processor issues an alarm through the alarm circuit.

[0008] Preferably, a PC system server is further included, the single-chip processor uploads the status information of the tested cable collected by the collection circuit to the PC system server, and the PC system server stores data of the status information.

[0009] Preferably, the single-chip processor uploads the status information of the tested cable to the PC system server via a CAN bus.

[0010] Preferably, it further comprises a line selection switching circuit, and the line selection switching circuit switches the circuit through a relay to realize switching between a real-time monitoring mode and a user monitoring mode of the state of the tested cable.

[0011] Preferably, the alarm circuit is connected to an LED indicator light, and the alarm circuit issues an alarm by energizing the LED indicator light.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting the single-chip microcomputer processor to be connected with the monitoring circuit, the acquisition circuit and the alarm circuit at the same time, the monitoring circuit can perform real-time detection of the measured cable through the optical coupler. When the optical coupler detects that the broken state of the measured cable has changed, the acquisition circuit collects the state information of the measured cable through the operational amplifier to determine whether the cable is really broken. When it is determined that the cable is broken, the single-chip microcomputer processor will issue an alarm through the alarm circuit, so that it can monitor in real time whether the measured cable is broken, and issue a cable break alarm in time when it is broken, and collect the cable state information at this time, so as to quickly locate the problem cable, analyze the cause of the cable break failure, and efficiently and accurately handle the cable failure, which is conducive to reducing the cable maintenance pressure of the station and improving the cable maintenance management level.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , 2 As shown, the utility model provides a device for real-time monitoring of the cable breakage status, comprising a single-chip processor 1, the single-chip processor 1 is connected with a monitoring circuit 2, a collection circuit 3, and an alarm circuit 4;

[0020] The monitoring circuit 2 performs real-time detection on the cable 5 under test through the optical coupler 6. When the optical coupler 6 detects that the broken state of the cable 5 under test has changed, the acquisition circuit 3 collects the state information of the cable 5 under test through the operational amplifier 7 and determines whether the cable is really broken. When it is determined that the cable is broken, the single-chip processor 1 issues an alarm through the alarm circuit 4.

[0021] Specifically, in this embodiment, by setting the single-chip processor 1 to be connected to the monitoring circuit 2, the acquisition circuit 3, and the alarm circuit 4 at the same time, the monitoring circuit 2 performs real-time detection on the measured cable 5 through the optical coupler 6. When the optical coupler 6 detects that the broken state of the measured cable 5 has changed (such as a sudden large change in the cable voltage value or current value), the acquisition circuit 3 collects the state information of the measured cable 5 through the operational amplifier 7 to determine whether the cable is really broken; when it is determined that the cable is broken, the single-chip processor 1 then issues an alarm through the alarm circuit 4, so that it can monitor in real time whether the measured cable 5 is broken, and issue a cable break alarm in time when it is broken, and collect the cable state information at this time, so as to quickly locate the problem cable, analyze the cause of the cable break failure, and efficiently and accurately handle the cable failure, which is conducive to reducing the cable maintenance pressure of the station and improving the cable maintenance management level.

[0022] In addition to monitoring the cable breakage status specifically compared to the existing technology, this device also has the advantages of small size, modularity and pluggability, suitable for railway signal machinery room combination frame or distribution board, easy installation and use, and long service life.

[0023] In an optional embodiment, if Figure 1 , 2 As shown, the device also includes a PC system server 8. The single-chip processor 1 uploads the status information of the tested cable 5 collected by the collection circuit 3 to the PC system server 8, and the PC system server 8 stores the data of the status information.

[0024] Specifically, after obtaining the relevant status information data of the cable break fault, the PC system server 8 can automatically analyze and locate the cable break fault by calling the cable diagnosis function, thereby providing more fault location and nearby reference information, so that the fault information can be obtained in a timely and accurate manner without manual investigation, providing more technical data support for precise processing and solving of problems.

[0025] Wherein, in an optional implementation manner, as Figure 1 , 2 As shown, the single-chip processor 1 uploads the status information of the tested cable 5 to the PC system server 8 via the CAN bus 9.

[0026] In an optional implementation, the device further includes a line selection switching circuit 10, which switches the circuit via a relay 11 to implement switching between a real-time monitoring mode and a user monitoring mode for the state of the tested cable 5.

[0027] Specifically, by setting the line selection switching circuit 10, the line selection switching circuit 10 can switch the circuit through the relay 11, thereby realizing the switching of the real-time monitoring mode and the user monitoring mode of the state of the tested cable 5, thereby facilitating the adjustment of the required monitoring mode to select the monitoring mode that is more suitable for the current situation.

[0028] In an optional embodiment, if Figure 2 As shown, the alarm circuit 4 is connected to the LED indicator light 12, and the alarm circuit 4 makes the LED indicator light 12 powered on to emit light to give an alarm.

[0029] Specifically, in this embodiment, by connecting the alarm circuit 4 to the LED indicator light 12, when the cable is broken, the LED indicator light 12 is powered on and flashes to achieve the purpose of alarm. In other embodiments, the alarm circuit 4 can also be connected to a buzzer alarm, so that the buzzer alarm can emit a buzzing sound to achieve the purpose of alarm.
