Description

Technical Field

[0001] The present invention relates to the technical field of noise monitoring, and in particular to a movable noise monitoring device for power transmission and transformation equipment. Background Art

[0002] In recent years, with the rapid development of economy, cities are constantly expanding, various power-consuming equipment are constantly superimposed, the dispatching maximum load and annual power consumption records are refreshed again and again, and the construction tasks of power transmission and transformation facilities are heavy, especially the number of UHV power transmission and transformation facilities is increasing year by year. At the same time, with the improvement of people's living standards, people attach great importance to their health, and substation noise has become the target of public criticism, which has led to a great impact on the construction progress of power transmission and transformation facilities, which is equivalent to adding insult to injury for the increasingly serious power supply task pressure, and has also suffered considerable losses in terms of cost.

[0003] With the implementation of the new "Construction Project Environmental Protection Management Regulations" and the transformation of the environmental protection responsible body of construction projects, the ecological and environmental authorities have gradually increased their requirements for environmental protection control of construction projects, which has put forward higher requirements and challenges for the full process and all-round environmental protection control of power grid construction projects. At the same time, in recent years, noise complaints and disputes in urban substations have been increasing year by year. After the company becomes the responsible body for project environmental protection acceptance, it will directly face complaints or lawsuits from the public. Therefore, it is of great significance to monitor the noise of substations. However, in the actual noise monitoring process, due to the requirements of noise monitoring on the environment, such as excessive wind speed, the accuracy of noise monitoring results will decrease, and even noise monitoring cannot be carried out. For example, the location of noise monitoring should not be blocked, such as walls. In the existing noise monitoring scheme, the operation and maintenance personnel need to use independent wind speed monitoring equipment to determine whether noise monitoring can be carried out. After meeting the requirements, the noise sensor needs to be installed on the upper end of the wall to reduce the impact of the surrounding environment and other walls on noise monitoring. This leads to a large workload for the operation and maintenance personnel and affects the efficiency of noise monitoring. Summary of the invention

[0022] In this embodiment, the noise monitoring device may also be provided with an alarm module, and the alarm module is configured such that when the digital noise signal obtained by the signal processing module 29 is greater than a threshold value, the alarm module alerts the mobile terminal device. The alarm method may be a text message alarm or a WeChat alarm. Mobile terminal devices include mobile phones and computers. Of course, the server may also provide an alarm function to facilitate users to understand the situation at the first time and make timely corrections.

[0023] In one embodiment, the noise monitoring device also includes a communication module 23 that is connected to the server, and the communication module 23 includes a first transmission network and a second transmission network, which is used to switch to the second transmission network when the first transmission network cannot transmit data normally, and upload the data bound by the signal processing module 29 to the server. In this way, the data is uploaded in a dual-network backup manner, which greatly avoids data loss due to network failures and other reasons during the transmission process. In addition, in one embodiment, the first transmission network and the second transmission network can adopt networks based on different principles to adapt to the situation where the signal strength of different networks in different environments is different. For example, the communication module 23 can adopt one or more of 3G network, 4G network, 5G network, Wi-Fi, NB-IoT, and LoRa.

[0024] In this solution, a noise sensor 21 is used to collect external noise. The noise sensor 21 can collect a wide range of sound waves. For example, a noise sensor that supports the collection of sound waves in the range of 20Hz to 20kHz can be used. The device does not need to switch gears according to the size of the sound wave, which simplifies the circuit structure and reduces production costs. A meteorological monitoring module 24 is set up to monitor weather conditions, which is convenient for users to study noise data based on weather conditions.

A GPS positioning device is provided to facilitate users to conduct classified research on different areas.

[0032] like Figure 3 As shown, the present invention also provides a mobile noise monitoring system for power transmission and transformation equipment, comprising: a server 100, a user terminal 200 and a mobile noise monitoring device 300 for power transmission and transformation equipment as described in any one of the first aspects, wherein the server 100 is respectively connected in communication with the user terminal 200 and the mobile noise monitoring device 300 for power transmission and transformation equipment; The mobile noise monitoring device 300 for power transmission and transformation equipment is arranged at the substation to be noise monitored, and is used to upload the bound location information, meteorological data and digital noise signal to the server 100; The server 100 is used to send an alarm message to the user terminal 200 of the operation and maintenance personnel when it is determined that the noise signal of the substation to be monitored is greater than a preset threshold.

[0033] The server should also be equipped with a second memory for storing noise data so that users can view and trace the data at any time.

[0034] In this way, when the operation and maintenance personnel are next to the noise monitoring device, they can know the monitored noise situation through the alarm module of the noise monitoring device. When the operation and maintenance personnel are not next to the noise monitoring device, the operation and maintenance personnel can know the current noise monitoring situation through the alarm prompt sent by the server 100 to the user terminal 200 of the user, thereby satisfying the situation that is applicable to both the operation and maintenance personnel and whether they are next to the noise monitoring device.
