Foreword On July 11, 2022, in order to effectively strengthen the fire prevention and control work of hotels and hotels, and resolutely prevent and curb the occurrence of major and extraordinarily large fire accidents, the Ningbo Fire Rescue Detachment grasped the characteristics of the season and built a fire safety "firewall" from three aspects: strengthening inspection, implementing supervision, publicity and guidance, improving the fire prevention and control level of hotels and hotels, and ensuring that the fire situation continued to be stable
.

Pay attention to daily supervision and special inspections, and target rectification and eliminate hidden dangers
.

Combined with the characteristics of summer fire prevention work and the law of fire occurrence, the detachment combines daily supervision with staggered inspection, highlights the fire prevention work such as electricity, gas and fire in hotels, implements various preventive measures, strengthens fire safety inspections of key parts such as electrical lines, equipment, kitchens, and various warehouses, and strictly prevents fire accidents
caused by short circuits, overload and other factors.

At the same time, carry out special inspection work, go deep into the EEL Eel E-sports Hotel, Meixuan Hotel, Tuke Hotel and other operations to check the implementation of fire safety system, fire fighting facilities operation, fire fighting facilities, safe evacuation signs, pipeline well blockage, electrical gas management and control room duty emergency treatment and other issues, the inspection of the fire door found not to be normally closed, fire hydrants are blocked, fire hose damage and other hidden dangers, the inspectors pointed out on the spot, and ordered timely rectification, Earnestly achieve centralized investigation without omission, hidden dangers rectification does not stay overnight, and safety inspection does not slacken
.

Pay attention to the implementation of responsibilities and personnel training, and dynamically control responsibilities
.

The detachment requires all hotels and hotels to clarify the fire safety manager, responsible for the fire safety management of the building and the building, establish and improve the fire safety management files, sign the fire safety responsibility letter at all levels, organize and manage the regular fire inspection and inspection, strictly implement the fire electricity safety management system, regularly test and maintain electrical lines and gas pipelines, and eliminate potential safety hazards
in a timely manner.

At the same time, supervise and urge hotels to strengthen the "four capabilities" construction and staff fire safety training, do a good job in pre-job training, popularize fire control knowledge, and implement the 24-hour duty system of fire control room duty personnel, train fire administrators to operate fire fighting equipment skillfully, and add a layer of safety to
the hotel and hotel.

Pay attention to on-the-spot propaganda and front-line communication, and clearly lead to a strong consciousness
.

Combined with the actual situation of fire knowledge and escape skills mastered by various hotels and hotels, the detachment organized publicity personnel, town street grid members and fire volunteers to post and distribute fire safety publicity materials, explain fire safety knowledge "face to face", and regularly organize hotel management personnel and practitioners to carry out fire knowledge lectures and fire skills training
.

At the same time, in the prominent position of each hotel to set up a fixed fire propaganda display board, fire guidance signs, etc.
, according to the characteristics of different hotels, timely and dynamic update of fire safety common sense, fire cases and other content, so that the elements of fire safety penetrate into the hearts of every staff and accommodation, effectively disseminate fire safety knowledge, improve the public's fire safety awareness
.

1.
Problem analysis combined with reality, and through the problems found in the inspection, there are more safety hazards in the hotel: 1) The building structure itself, such as insufficient fire spacing, reduced fire resistance level of the building, etc.
, is easy to cause the rapid spread of
fire.

2) Dense personnel, frequent flow, difficult management, once a fire occurs, there is a phenomenon of hecticism, in the break between breaks, especially at night personnel neglect management and prevention period, it is easy to cause major casualties
.

3) The risk of wire leakage, short circuit and ignition increases during the rainy season
.

4) Fire, electricity, gas and other aspects of the disaster factors, kitchen, operation room, boiler room and other parts are dense areas with fire, gas, liquid, gas fuel leakage or careless use of fire, will cause fire, air conditioning, television, computer, water dispenser and other electrical equipment is increasing, the possibility of electrical equipment caused by fire is also increasing
.

5) Public electrical equipment runs for a long time, there is no professional electrician to investigate, can not be real-time supervision, after the failure is very easy to cause fire
.

2.
The solution sets up Acrel-6000 of Acrel-6000 for electrical circuits, equipment short circuits, overload and other factors to achieve electrical safety monitoring
such as leakage, overload, short circuit, cable temperature abnormality and so on.

Using fieldbus communication technology, the host computer management software can always monitor the operation of the site, when the line leakage, temperature abnormality to reach the early warning value, can immediately issue a sound and light alarm signal, notify the relevant personnel to timely check the electrical fire hazards
.

With the event storage function monitoring detector can record the time, type, parameters of the alarm occurrence, according to the alarm record can analyze the on-site electricity situation, for the establishment of fire safety management files to provide a basis
.

The use of guide rail installation, is conducive to the later transformation
of the hotel.

Flexible networking, host plus detector two-layer structure networking mode, cost-effective, the use of RS-485 network, communication real-time high, duty personnel can view information in real time, if the hotel floor is more, the environment is complex, suitable for multiple host networking, convenient regional management
.

The following figure is the on-site installation diagram of a hotel guide rail monitoring detector, which adopts bus connection and simple and convenient
construction wiring.

It is also necessary to set up a fire equipment power monitoring system, which can monitor the power supply of fire equipment in real time, by detecting the power supply of fire equipment voltage, current, switch status and other related equipment power supply information, so as to determine whether the power supply equipment has broken circuit, short circuit, overvoltage, undervoltage, misphase and overcurrent (overload) and other fault information and real-time alarm, record alarm information, for the reliable and stable operation of fire fighting equipment to provide protection
.

This system is composed of a power supply status monitor, a regional extension, a sensor and supporting accessories for fire fighting equipment, using a centralized power supply mode, providing DC24V safety voltage to the field sensor through the monitor, effectively ensuring the stability and safety of
the system.

In view of the phenomenon that the fire door is not kept normally closed during the inspection, the Acquaray fire door monitoring system can be set up to monitor
the fire door in real time.

Fireproof separators such as fire doors are widely used in the fire protection design of construction projects, but because of their unreasonable design, improper selection, inadequate monitoring and other reasons, the fire doors cannot give full play to their isolation role
.

The fire door monitoring system is composed of a fire door monitor (host) and each terminal equipment, that is, an integrated door magnetic switch, an integrated electric door closer, etc.
, through the centralized control of the host, real-time monitoring of the opening, closing and fault status of the fire door of the evacuation channel, displaying the open circuit, short circuit and other fault signals
of the terminal equipment.

The system uses fire fighting bus to connect the modules to each other, when a short circuit, short circuit and other faults occur, the fire door monitor (host) can issue an alarm signal, indicate the alarm part and save the alarm information
.

If the built environment is complex and changeable, you can also expand the circuit through the regional extension and flexibly network
.

The fire door monitor (host) is set in the fire control room to monitor the opening, closing and fault status
of the fire door of the evacuation channel in real time.

If the normally closed fire door is in an abnormal open state, the host will issue a sound and light alarm signal in time, display the alarm part, facilitate the timely inspection of the duty personnel, and avoid the situation
that the fire door found in the inspection is not kept normally closed.

The following figure shows the scene map of the host of the three systems installed in the fire control room, which is simple and convenient for
wall-mounted installation.

Touch LCD display, full Chinese display, can be connected to the mouse, keyboard, monitor, convenient on-site operation, with operation, silence, fault and so onIndicator lights, which facilitate
the inspection and recording of duty personnel.
