Illustratively, in a warehouse scenario for coiled cables, the coiled cable stack is stored in a warehouse. Each coiled cable is provided with the abnormal cable flooding positioning device based on indoor positioning, so that abnormal flooding positioning prompt can be conveniently carried out. When a certain coiled cable is abnormal in water immersion, the cable water immersion abnormity positioning device based on indoor positioning detects the abnormal condition and positions the real-time position information of the cable, and then reports the water immersion abnormity prompt and the real-time position information to a system monitoring background. The warehouse management personnel can determine that the disc-mounted cable at the corresponding position is abnormal in water immersion according to the abnormal water immersion prompt through the system monitoring background, and timely go to the abnormal water immersion condition treatment.
Specifically, the cable flooding abnormity positioning device based on indoor positioning connects the head end and the tail end of the coiled cable, and performs flooding abnormity detection of the coiled cable in real time. It can be understood that when the disc-mounted cable has the risk of flooding, the cable flooding abnormity positioning device based on indoor positioning can detect signals through the detection electrode of the flooding detection module, and then the flooding abnormity detection is carried out. And when the flooding abnormity occurs, the real-time position of the current coiled cable is positioned so as to position the flooding abnormity of the coiled cable in the warehouse and report the flooding abnormity.
Referring to fig. 2, a schematic diagram of structural connection of the cable flooding abnormity positioning device based on indoor positioning according to the embodiment of the present application is provided, wherein in the cable flooding abnormity positioning device based on indoor positioning, the processor 111 is respectively connected to the wireless communication module 112 and the flooding detection module 113, and the flooding detection signal is collected by the flooding detection module 113, so as to prompt the flooding abnormity of the cable currently coiled according to the flooding detection signal.

And reporting the abnormal immersion prompt and the real-time position information to a monitoring background for positioning the abnormal immersion prompt.
Specifically, referring to fig. 3, a schematic structural connection diagram of the submergence detecting module in the embodiment of the present application is provided, where an output end of the signal generator 1133 is connected to one end of the primary coil of the transformer, and the signal generator 1132 is configured to output a low-frequency alternating current signal to the converting circuit; the other end of the primary coil of the transformer 1132 is connected with the input end of the conversion circuit 1133, and the two ends of the secondary coil of the transformer 1132 are used for being connected with the detection electrode 1131 during monitoring of flooding; the conversion circuit 1134 is configured to convert the low-frequency ac signal into a dc voltage signal and output the dc voltage signal to the non-inverting terminal of the comparator 1135, when the output terminal of the comparator 1135 outputs a low level, it is determined that the detection electrode is not immersed, and the comparator 1135 compares the low-frequency ac signal with the dc voltage signal to output an immersion detection signal. It can be understood that the low-frequency alternating current signals output by the detection device are different according to two different detection results of soaking and non-soaking, and the soaking detection signals obtained through comparison of the comparator are different. And then, whether the current coiled cable is abnormally soaked or not can be determined through the soaking detection signals with different levels.
More specifically, the signal generator may be a simple square wave signal generator, or a signal generator implemented by an operational amplifier and a comparator, or a signal generator implemented by a non-operational amplifier and a non-comparator. The signal generator implemented by the operational amplifier and the comparator may specifically be: the device comprises a phase-shifting sine wave signal generator, a Venturi bridge sine wave signal generator, an orthogonal sine wave signal generator, a rectangular pulse signal generator and a triangular wave signal generator; the signal generator implemented by the non-operational amplifier and the non-comparator may be specifically: the circuit comprises an oscillation circuit signal generator constructed by adopting triodes, an oscillation circuit signal generator realized by a time-base circuit chip and an oscillation circuit signal generator realized by a logic circuit with an inverter.
The conversion circuit may be embodied as an absolute value circuit, a differential amplification circuit, and an integration filter circuit, which are connected in sequence. The low-frequency alternating current signal is input into the input end of the absolute value circuit, and is output to the in-phase end of the comparator after passing through the differential amplifying circuit and the integral filter circuit.
Optionally, the detection electrode is connected to two ends of the secondary coil of the transformer, one end of the primary coil is connected to a power supply (4.5V) through a pull-up resistor, and the other end of the primary coil is connected to the output driving end of the signal generator. The signal generator is specifically a square wave signal generator which generates a square wave with the frequency of 50-100 Hz and the potential symmetrical to 4.5V of the power supply, and the square wave signal is coupled to the detection electrode through a transformer. When no water immersion occurs, the resistance at the two ends of the detection electrode is infinite, and the transformer is in an idle state. At the moment, the voltage at the connection part of the primary side of the transformer and the pull-up resistor fluctuates in a narrow range in an equal period relative to the power supply of 4.5V under the driving of a square wave signal. The fluctuation signal is adjusted by an absolute value circuit, a differential amplifying circuit and an integral filter circuit to be changed into a direct current voltage signal, the direct current voltage signal is output to the in-phase end of a comparator, the amplitude of the direct current voltage signal is lower than the reference voltage of the anti-phase end of the comparator, and the output end of the comparator is a low-level immersion detection signal. When the water immersion occurs, the resistance at two ends of the detection electrode is reduced, and the load of the transformer is increased. At the moment, the voltage at the connection of the primary side of the transformer and the pull-up resistor increases relative to the fluctuation amplitude of 4.5V of the power supply. After the fluctuation signal is adjusted by an absolute value circuit, a differential amplifying circuit and an integral filter circuit, the output direct-current voltage signal is obviously improved compared with the signal without water. The voltage exceeds the reference voltage, the output level of the comparator is inverted, and the high-level submergence detection signal is output.
In the whole immersion detection process, because the detection electrode is always provided with a low-frequency alternating current signal, no direct current component exists, and therefore, the electrochemical corrosion and polarization phenomena can not be generated, the immersion detection is more accurate, and the error alarm can not be generated. Simultaneously through the detection signal that soaks of different levels also can the accurate survey detecting electrode take place to soak, and then whether the accurate dish dress cable of confirming appears soaking unusually, optimize the unusual detection effect that soaks.
Fig. 4 is a flowchart of a cable flooding anomaly positioning method based on indoor positioning according to an embodiment of the present application, where the cable flooding anomaly positioning method based on indoor positioning according to the present embodiment may be executed by a processor of a cable flooding anomaly positioning device based on indoor positioning, and the following description will be given by taking the processor as an example of a main body for executing the cable flooding anomaly positioning method based on indoor positioning. Referring to fig. 3, the cable flooding anomaly positioning method based on indoor positioning specifically includes:
s110, receiving a submergence detection signal reported by a submergence detection module, and generating a submergence abnormity prompt when judging that the detection electrode is submerged based on the submergence detection signal;
s120, sending ranging signals to at least three ranging terminals arranged at fixed positions through a wireless communication module, receiving reply signals of the ranging terminals, and positioning real-time position information of the current coiled cable based on the receiving time of the reply signals, the sending time of the ranging signals and the position information of the ranging terminals;
and S130, reporting the abnormal immersion prompt and the real-time position information to a system monitoring background.
Specifically, based on the submergence detection signal detected by the submergence detection module, the processor judges whether the current coiled cable is abnormally submerged through the submergence detection signal. When the processor monitors the abnormal immersion, the processor acquires the immersion detection signal in real time to analyze the abnormal immersion. It is understood that the submergence detecting signal is a level signal of different level states. And under the condition of carrying out abnormal immersion analysis, the processor determines the level state of the immersion detection signal, judges that the detection electrode is not immersed when the immersion detection signal is a low level signal, and judges that the detection electrode is immersed when the immersion detection signal is a high level signal.
Optionally, the processor may be configured with a transistor and a relay, and the transistor and the relay are connected to the submergence detecting module, and when the submergence detecting signal output by the submergence detecting module is a low-level signal, the transistor is not driven to be conducted, so that the relay is switched to a conducting state. When the immersion detection signal output by the immersion detection module is a high level signal, the triode can be driven to be conducted so that the relay is switched to be in a conducting state. Based on the characteristic, the processor can accurately determine whether the detection electrode is immersed by detecting the conduction and the transition state of the relay as an immersion detection signal.
Furthermore, as the detection electrode is arranged on the coiled cable, when the detection electrode is soaked, the current coiled cable can be determined to be abnormal in soaking, and the processor generates a soaking abnormity prompt to report the abnormal condition of the system background prompt.
Further, since the coiled cables are stacked in the warehouse, it is difficult for the custody staff to determine where the flooding abnormality occurs in the warehouse only by the flooding abnormality prompt. Therefore, the indoor positioning of the current coiled cable is further carried out, the real-time position information of the current coiled cable is obtained, and the abnormal water immersion positioning prompt of the current coiled cable is carried out.
The processor broadcasts ranging signals to at least three ranging terminals arranged at fixed positions in the warehouse through the wireless communication module, and then receives reply signals of the ranging terminals. And then the real-time position information of the current coiled cable is positioned based on the interaction of the wireless communication module and the three ranging terminals.
The processor determines the linear distance between the current coiled cable and the ranging terminal based on the receiving time of the reply signal and the sending time of the ranging signal; and positioning the real-time position information of the current coiled cable based on each linear distance and the position information.
It can be understood that the transmission time T of the ranging signal is based on 1 And a reception time T of the reply signal 2 Combining the transmission rate V of the signal and the reflection time T from the ranging terminal receiving the ranging signal to the sending back of the reply signal n And calculating the linear distance L between the current coiled cable and the ranging terminal. The linear distance L is calculated by the formula:
determining the linear distance L between the current coiled cable and each ranging terminal based on the calculation formula (1) 1 、L 2 、L 3 .....L n . Further combining the position information (x) of at least three ranging terminals 1 ，y 1 ，z 1 )，(x 2 ，y 2 ，z 2 ) And (x) 3 ，y 3 ，z 3 ) The real-time position information (x) of the current coiled cable can be calculated 0 ，y 0 ，z 0 )。
The calculation formula of the real-time position information of the current coiled cable is as follows:
based on the known linear distance and the position information of the ranging terminal, substituting the known linear distance and the position information of the ranging terminal into the formula 2, the space coordinate of the current coiled cable, namely the real-time position information (x) of the current coiled cable can be obtained through simultaneous solution 0 ，y 0 ，z 0 )。
Based on the determined real-time position information, the processor uploads the real-time position information and the generated abnormal immersion prompt to a system detection background so as to perform abnormal immersion positioning prompt of the current coiled cable.
Optionally, the system monitoring background is used for monitoring one end of the corresponding system, and the abnormal immersion prompt can be marked in a pre-constructed three-dimensional warehouse model based on the abnormal immersion prompt and the real-time position information, so that warehouse management personnel can visually determine which position of the warehouse is abnormal in immersion, and accurately go to the corresponding position to process the abnormal immersion of the corresponding coiled cable.
Optionally, the cable flooding abnormity positioning device based on indoor positioning further comprises a humidity detection module, which is used for detecting and collecting real-time humidity data and reporting the real-time humidity data to the processor; and the processor is also used for reporting the real-time humidity data to the system monitoring background when the detection electrode is judged to be soaked.
And when judging that the detection electrode is immersed in water, the processor acquires the real-time humidity data of the current coiled cable and reports the real-time humidity data to the system monitoring background.
The system background compares the real-time humidity data with a set humidity threshold value, and when the real-time humidity data exceeds the set humidity threshold value, whether the current coiled cable is abnormal in water immersion can be verified.
The set humidity threshold value is determined according to actual humidity data when the head end and the tail end of the coiled cable are abnormally soaked. And when the real-time humidity data reaches the set humidity threshold value, indicating that the current coiled cable is abnormal in water immersion. And if the real-time humidity data does not exceed the set humidity threshold, the current storage state of the coiled cable is normal. Whether the abnormal prompting of the water immersion has the false alarm condition is verified through the real-time humidity data, the accuracy of the water immersion detection can be further improved, and the abnormal positioning prompting effect of the water immersion is optimized.
In one embodiment, the processor further compares the real-time humidity data with historical humidity data to determine humidity change data, and when the humidity change data reaches a set change threshold, reports a humidity change prompt to the system monitoring background. It can be understood that if a certain time node processor finds that the humidity data of the coiled cable has large changes in a short time, even if the real-time humidity data does not exceed a set humidity threshold value, the condition needs to be prompted in time, and the water immersion abnormity is early warned in time, so that the water immersion protection effect is further optimized.
Based on this, by configuring a set change threshold, when the real-time humidity data is compared with the historical humidity data detected last time by the humidity detection module, and the humidity change data exceeds the set change threshold, it indicates that the humidity data of the current coiled cable has a large change in a short time, and the processor triggers to perform humidity change prompt, so that the storage safety of the current coiled cable is guaranteed.
When the detection electrode is judged to be soaked based on the soaking detection signal by receiving the soaking detection signal reported by the soaking detection module, a soaking abnormity prompt is generated; sending ranging signals to at least three ranging terminals arranged at fixed positions through a wireless communication module, receiving reply signals of all the ranging terminals, and positioning real-time position information of the current coiled cable based on the receiving time of the reply signals, the sending time of the ranging signals and the position information of all the ranging terminals; and reporting the abnormal immersion prompt and the real-time position information to a system monitoring background. Adopt above-mentioned technical means, can detect the soaking anomaly through the soaking detection signal of soaking detection module to through the accurate abnormal position that soaks of indoor location technique, carry out the soaking anomaly location and the report of storage cable conductor, promote the security of coiled cable storage, avoid user's unnecessary loss, optimize the storage management effect of coiled cable.
