Description

Fire hydrant management system based on Internet of things

Technical Field

The utility model relates to a municipal administration tax management system, especially a fire hydrant management system based on thing networking.

Background

In life, fire-fighting water has the difficulties of easy destruction, difficult maintenance, complex management and the like. According to statistics, the reason for causing huge economic loss of fire and more than 70% of casualties is poor management. Fire water pressure can not be supervised for 24 hours, the phenomenon that water supply pressure is not unstable enough is difficult to record and process, once a disaster phenomenon occurs, the fire water has the problems of intermittent water supply and no water supply, and the fire water is stolen, water leakage and the like cause precious water source waste and can not be found and processed at the first time. In addition, other emergencies cannot inform corresponding maintenance personnel and management units in time.

Various problems of municipal fire hydrants are summarized as follows:

1. illegal use of the fire hydrant avoids water waste, such as car washing, temporary construction, landscaping and the like, even in some shops, the municipal fire hydrant is at the door opening of the shop, so that the traffic of vehicles and personnel is influenced, business delay is feared, and the municipal fire hydrant is removed and moved without permission;

2. water leakage or seepage or illegal water theft of the fire hydrant due to self failure or long-term overhaul;

3. due to various reasons such as road reconstruction construction and vehicle impact, the municipal fire hydrant is damaged, and the smooth development of fire fighting and fire extinguishing rescue is seriously influenced at key moment;

4. some lawlers steal municipal hydrants.

5. Due to the reasons of pipelines or fire hydrants, and the like, the water pressure is unstable or abnormal, and the development of fire rescue is influenced at a critical moment.

6. Municipal fire hydrants are not well supervised.

Current situation and difficulty of current fire hydrant management

1. At present, fire hydrants do not have effective and timely supervision measures and can only depend on the inspection of water department inspectors.

2. The fire hydrant is huge in quantity, and the monitoring cannot be achieved in real time only by people, so that the supervision is not in place necessarily.

3. Maintenance and service implementation is not possible, such as described in point 2 above.

4. In addition to seemingly observable problems (e.g., water leaks, jolts, etc.), the biggest pain point is that water pressure is more difficult to detect manually in real time, and so this problem is the most troublesome problem in water departments and fire departments.

Along with the development of science and technology and the promotion of people's standard of living, the wisdom city, wisdom thing allies oneself with becomes the more and more urgent demand of people, various electrical apparatus in the family, the running water in the life, the air quality, fire control facility, municipal administration equipment, factory equipment etc. all need to have the management of wisdom to get up, along with the improvement of sensor technology to and the arrival of 5G, the transmission problem of solving the last kilometer of thing networking is clear gradually, and LoRa and NB-IoT are just solving the transmission channel of last kilometer at present.

The Internet of things (IOT) has three main structures: a sensing layer, a network layer and an application layer.

Firstly, a sensing layer (information acquisition layer), namely, RFID, sensors and the like are utilized to acquire the information of an object at any time and any place;

a network layer (information transmission layer) which can accurately transmit the information of the object in real time through the fusion of various telecommunication networks and the Internet;

and the application layer (information processing layer) processes the information obtained by the sensing layer, and realizes the practical application of intelligent identification, positioning, tracking, monitoring, management and the like.

LoRa and NB-IoT are two low-power-consumption wide area network communication technologies with the most development prospect at present, the requirements of long distance and low power consumption in wireless transmission of the Internet of things can be met, and with the continuous maturity of the technology of the Internet of things, the Internet of things plays an important role in smart city construction, wherein LoRa and NB-IoT technologies have to be said.

LoRa (Long Range) is an ultra-long distance wireless transmission scheme based on spread spectrum technology adopted and popularized by Semtech corporation in America. The LoRa network mainly comprises a terminal (which can be internally provided with a LoRa module), a gateway (or called a base station), a Server and a cloud, and application data can be transmitted in a two-way mode.

NB-IOT (NB-IOT), a technology standard defined by 3GPP standardization organization, is a narrowband radio frequency technology specifically designed for the internet of things.

The biggest difference between LoRa and NB-IoT is frequency band, service quality and cost. In short, LoRa works in an unlicensed frequency band below 1GHz, so that additional payment is not needed in application, but a network is needed to be established independently, the service quality cannot be compared with that of an operator, and the indoor penetration capability is slightly superior. NB-IoT and cellular communication use licensed bands below 1GHz, but can guarantee quality of service.
