Description

Technical Field

[0001] The present application relates to the technical field of protection for live working on power transmission lines, and in particular to a live working shielding suit capable of real-time monitoring of connection status and vital sign parameters. Background Art

[0002] Live working is an important technical means for the operation and maintenance of UHV power grids. It can not only eliminate defects in transmission lines in a timely manner, but also avoid the economic losses caused by power outages for maintenance. A full set of qualified and firmly connected shielding clothing is an important protective measure for workers working live in high-voltage electric fields. Live working shielding clothing usually consists of clothes, pants, gloves, socks and their corresponding shunt wires and connectors. Based on the Ferrari cage principle, the shielding clothing enables various parts of the outer surface of the human body in a high-voltage electric field to form a uniform potential distribution, reduce the potential difference, and reduce the risk of electric shock and arc damage to workers in high-voltage electric fields by shielding strong electric fields and bypassing potential transfer currents.

[0003] It is difficult for existing shielding suits to remotely monitor the connection status of shielding suits and the vital signs of operators in real time. The shielding suit needs to be connected to each other as a whole through the shunt wire connector to achieve the effect of voltage equalization and current diversion. However, due to the stretching and contraction of the shunt wire caused by the operation, the connector is repeatedly twisted, which can easily cause the two terminals of the connector to loosen or even disconnect as a whole, significantly reducing the conductivity of the current in the shielding suit. In terms of connection status monitoring, existing shielding suits lack effective monitoring methods, and this disconnection action is not easy to be detected by operators in time, which can easily cause arc discharge to burn operators and cause safety accidents.

[0004] When workers wear shielding suits to perform live maintenance tasks, the different thermal environment intensities and enclosed spaces inside the suits will cause different degrees of physiological and psychological reactions in the workers, leading to changes in body temperature, heart rate, blood pressure and other vital signs, which can easily cause workers to become tired, weak, confused, and have difficulty concentrating on work, and lead to safety issues such as decreased attention, thereby increasing the probability of accidents at live work sites. In terms of vital sign monitoring, existing shielding suits are not equipped with compatible flexible wearable devices and lack the perception of workers.

[0005] In addition, due to the electromagnetic shielding effect of the shielding suit itself, it is difficult for the flexible wearable vital signs monitoring device placed in the shielding suit to communicate with the remote background through the shielding suit. The power frequency electromagnetic field strength in the ultra-high voltage live working environment is high, and conventional communication methods are susceptible to strong noise and interference. These interferences may overlap with the useful signals of the shielding suit connection status monitoring and the vital signs monitoring of the operator, forming serious channel interference, reducing the reliability and effectiveness of the communication, and resulting in the inability to reliably report the shielding suit monitoring information to the remote background. Summary of the invention

[0025] The vital signs detection module is a flexible wearable bracelet, which is used to detect microcurrent data and vital signs parameters on the body surface of personnel working with live wires.

[0026] The alarm unit of the badge module includes: a two-color LED light, a flat vibrator and a buzzer alarm.

[0027] The present application provides an embodiment as follows: the badge module is fixed to the split shielding suit by nylon Velcro, and is used for centralized reporting of monitoring information and displaying sound and light alarm information. Six two-color LED lights are set on the top of the badge module, corresponding to the six received on-off status signals.

[0028] The vital sign detection module and the distributed connection status monitoring module both include a Bluetooth slave module, and the Bluetooth slave module and the Bluetooth master module of the badge module form a local communication network; Improved adaptive frequency hopping technology based on frequency selection function of channel assessment based on power spectrum density estimation; Wireless communication between the Bluetooth slave module and the Bluetooth master module is carried out through the improved adaptive frequency hopping technology; The badge module also includes a remote communication module, which is a 4G communication module with an embedded SIM card for transmitting the packaged monitoring information back to the remote monitoring platform; the monitoring information includes: on / off status signals, microcurrent data and vital sign parameters.

[0029] The present application provides an embodiment as follows: the communication module is a Bluetooth slave communication module, which forms a local communication network with the Bluetooth master module of the badge module. The module applies adaptive frequency hopping technology improved for the complex electromagnetic environment of point operation, and enhances the anti-interference ability of the distributed connection status monitoring module for short-distance local self-organizing network communication.

[0030] The present application provides an embodiment as follows: the Bluetooth communication modules in the badge module, the distributed connection status monitoring module, and the vital signs monitoring module all apply the adaptive frequency hopping technology improved for the complex electromagnetic environment of live operation, and dynamically re-evaluate and include the previously excluded frequency channels by introducing the channel evaluation of power spectrum density estimation to reduce the probability of interference conflict and reduce the communication error packet rate, thereby improving the anti-interference ability of the distributed connection status monitoring module for short-distance local area self-organizing network communication. Specifically, a pseudo-random code sequence is first obtained at the transmitting end of the Bluetooth slave module, and then the frequency point sequence is determined by the pseudo-random sequence, and further corresponds to the corresponding frequency point to complete the frequency selection. According to the obtained communication frequency, a corresponding frequency hopping signal is generated, and the frequency hopping signal is multiplied by the modulated signal to obtain the actual transmission signal of the Bluetooth slave module. After frequency hopping demodulation, the channel quality evaluation method of power spectrum density estimation is used to obtain the channel quality of the complex electromagnetic environment of real-time live operation, and the frequency point used in the actual local area self-organizing network communication is controlled by the obtained frequency hopping frequency point sequence. At the receiving end of the Bluetooth slave module, a pseudo-random code sequence is obtained through the synchronization system, and then the same frequency hopping signal as the transmitting end is obtained. The original modulated signal is obtained by multiplying and filtering the received signal in the time domain, and then demodulated and decoded to obtain the on and off status of the shielding suit and the vital signs of the operator.

[0031] Bluetooth communication divides the communication frequency band into smaller frequency channels and quickly jumps between these channels when transmitting data packets to overcome external electromagnetic interference. When sending data packets, the interfered frequency channels will be tracked and avoided at any time. The adaptive frequency hopping technology improved for the complex electromagnetic environment of point operation adds a frequency selection function based on the channel evaluation of power spectrum density estimation on the basis of the frequency hopping communication system. Specifically, the received signal is first calculated. The autocorrelation function ,

[0032] in, is the number of sampling points. Then the estimated value of the autocorrelation function is Perform Fourier transform, and the Fourier transform result is the original signal The power spectrum ,

[0033] Then, use the original signal The power spectrum Divide by the bandwidth of the Bluetooth signal The power spectral density is calculated and used as an indicator for evaluating the channel quality in live working environments.

[0034]

[0035] Based on the power spectrum density estimation results, by setting the threshold Will receive signal The frequency points of the channel are divided into blocked and unblocked states. The frequency points with interference signal strength higher than the threshold value in the channel are considered blocked and classified as bad frequency points; conversely, the frequency points with interference signal strength lower than the threshold value in the channel are considered unblocked and classified as good frequency points. Frequency utilization To assist the optimal threshold The value of .

[0038] in is the minimum value of spectrum utilization in frequency hopping communication. is equivalent to When the maximum value is taken, the value of the frequency point with the highest interference intensity in the frequency point set is used. This ensures that as many frequency points as possible are used to avoid interference from complex electromagnetic environments in live working environments, and improves the communication quality of the Bluetooth modules of the badge module 3, the distributed connection status monitoring module 4, and the vital signs monitoring module 5.
