Description

Technical Field

[0001] The utility model relates to a self-diagnostic tail clip for diagnosing whether an analog signal is abnormal. Background Art

[0002] To improve production efficiency, the demand for minimizing equipment downtime is increasing. Even critical equipment and infrastructure are being asked to improve utilization. To meet this demand, monitoring equipment status to prevent unexpected downtime and enable planned maintenance and component replacement is currently the mainstream solution. Monitoring systems, however, require the deployment and collection of analog signals from numerous sensors for real-time monitoring and subsequent data analysis. These systems employ dozens or even hundreds of different types of sensors at each monitored location. Traditionally, there have been two main approaches to detecting sensor failures.

[0003] One approach is regular inspections, where technicians use a handheld multimeter to measure and record each sensor signal, then compare it to specified values ​​to determine if there are any issues. This method is suitable for measuring the output voltage of data acquisition equipment. However, when measuring sensor input and output voltage, current, power, or internal cable temperature and resistance, the original cable must be disassembled or specialized measuring tools must be used. This not only increases the inspection workload but can also easily lead to secondary failures during the measurement process.

[0004] Another approach relies on monitoring data trends. When an unusual change is detected at a specific point, technicians first analyze the data and then retest and compare sensor data on-site to determine whether the anomaly is due to a fault in the equipment itself or damage to the sensor or cable. This approach requires extensive troubleshooting experience, and judgment results vary from person to person, making accurate fault location impossible with simple criteria. Furthermore, the troubleshooting process is time-consuming and labor-intensive. When dealing with large and complex monitoring systems, data retesting and comparison requires significant manpower, making troubleshooting quite challenging.

[0005] To achieve high user satisfaction in condition monitoring services, it is essential to provide a device that can conveniently and flexibly detect sensors and cables. Tailclip is a common connector widely used to connect and secure various electrical connectors and cables. The signal self-diagnostic tailclip is an ideal solution for monitoring sensor and cable status. Summary of the Invention

[0006] This utility model provides a tail clip with signal self-diagnosis capabilities. By adding a detection circuit to a traditional tail clip, it can identify and determine abnormalities in sensor signals, making it suitable for self-diagnosis of acquisition system faults. The signal self-diagnosis tail clip is compact and easy to install. Without adding additional detection devices, it can monitor changes in voltage, current, resistance, temperature, and other signals of sensors and cables. It can also generate alarms for different fault signals based on set thresholds, reducing the workload of daily system maintenance and improving the overall system fault detection and isolation rates.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a tail clip with signal self-diagnosis capability, including a shell, a detection module, an LED module and a wireless module. The detection module, LED module and wireless module are built into the tail clip body to realize real-time detection and judgment of the sensor input and output signals, and display the status of the sensor and cable through the LED module, and send the obtained sensor and cable status information to the accessory dedicated portable inspection terminal via radio waves through the wireless module.

[0008] The housing is used for electrical connection and connection between cables, and is provided with mounting holes and slots for fixing the detection module, LED module and wireless module.

[0009] The detection module is installed in the middle of the tail clip and is divided into three parts: power supply, measurement and control. Among them: the power supply circuit is used to accept external voltage within ±30V and reduce the voltage to the specified voltage to provide the required power for the entire detection module, display module and wireless device; the measurement circuit is used to measure the external input voltage and current, the resistance value between the core wires, and the temperature of the core wires; the control circuit is used to process and summarize the measured signals for status display and data transmission.

[0010] The LED module is installed at the incoming line end of the housing, forming a ring on the outside and containing LED lamp beads to display the status of the sensor and cable.

[0011] The wireless module is installed at the outlet end of the housing and uses the Bluetooth low energy 2.4GHz communication standard to send the obtained sensor and cable status information to the attached dedicated portable inspection terminal via radio waves.

[0012] The beneficial effects of the present invention are:

Therefore, it can measure the voltage, current, resistance and temperature signals of the sensor and cable faster and more accurately than external measuring instruments, thereby determining abnormal conditions as early as possible.

[0014] 2. According to the present invention, without adding additional components and devices, the detection module 3, LED module 7 and wireless module 1 have been built into the tail clip, which can easily replace the tail clip used on the existing equipment.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 , 2 shows a tail clip with signal self-diagnosis capability of the present invention, comprising: a housing 2, a detection module 3, an LED module 7 and a wireless module 1.

[0021] The tail clip of the utility model has the signal self-diagnosis capability, and adds the detection module 3, the LED module 7 and the wireless module 1 to the original tail clip, which can realize the real-time detection and judgment of the sensor input and output signals, and inform the user of the status of the sensor and cable through the LED module 7 and the wireless module 1.

[0022] The housing 2 is used for electrical connection and connection between cables, and is provided with mounting holes and slots for fixing the detection module 3 , the LED module 7 and the wireless module 1 .

[0023] The detection module 3, mounted in the center of the tail clip, consists of three sections: power supply, measurement, and control. The power supply circuit 6 accepts an external voltage within ±30V and reduces it to a specified voltage to provide power to the entire detection module, display module, and wireless device. The measurement circuit 4 measures the external input voltage and current, the resistance between the core wires, and the core wire temperature. The control circuit 5 processes and aggregates the measured signals for status display and data transmission.

[0024] The LED module 7 is installed at the incoming line end of the housing 2, and is formed into a ring on the outside. There are LED lamp beads inside to display the status of the sensor and cable. When the detected signal is within the normal range, it displays blue; when the signal exceeds the normal range, it displays red and flashes; when the detection module 3 itself fails, it displays yellow.

[0025] The wireless module 1 is installed at the outlet end of the housing 2 and adopts the Bluetooth low energy (2.4GHz) communication standard to send the obtained sensor and cable status information to the attached dedicated portable inspection terminal via radio waves.

[0026] The self-diagnostic tail clip of the present invention is installed near the sensor side, and the power line and signal line need to be connected to the terminal blocks 8 at both ends of the tail clip respectively. The measurement circuit 4 in the built-in detection module 3 of the tail clip measures the voltage, current, resistance, temperature and other parameters on the input power line and signal line and makes a judgment through the control circuit 5. When the measured value is within the normal range, the controller sends a normal signal and the LED module 7 displays blue; when the measured value exceeds the set threshold, the control circuit sends a fault signal and the LED module 7 displays red and flashes, reminding the user to conduct timely inspection and maintenance. At the same time, a self-test function is designed in the detection module 3. When a fault is found in the tail clip itself, such as abnormal power output, measurement circuit fault, or communication fault, the LED module 7 displays yellow, informing the user to repair or replace it in time to avoid economic losses caused by misjudgment or malfunction.

[0027] When the dedicated portable inspection terminal approaches the tail clamp, the wireless module 1 automatically connects to the terminal and synchronizes real-time measurements of voltage, current, resistance, temperature, and other values ​​to the terminal via Bluetooth. This allows users to easily measure the operating status of each sensor and cable without needing to carry a multimeter or other measuring instruments. Furthermore, if a device experiences an anomaly, historical sensor and cable information can assist users in troubleshooting and locating the device.
