A coffee grinder with a cone-knife grinder places a conical knife disk at the bottom of the machine, and then cooperates with the outer ring knife disk for grinding. The coffee powder produced in this way will be closer to granular, and at the same time, the water absorption path of the coffee particles will become longer, and it will take more time for the inside to contact the water, which will result in the coffee powder being released within the first time. The soluble substances are less, and the concentration will not be too high in a short time.

Smart Security: Intelligent Evacuation Guidance Information System
Most of the evacuation guidance information in traditional buildings adopts the method of setting evacuation emergency lights and safety exit signs in fixed directions. According to the recent project bidding information of the new type of fire safety equipment integration enterprise, the company learned that these traditional settings cannot be adapted to the specific situation of the scene in the fire, especially in the large-scale fire, it is difficult to play a role, so the traditional The evacuation guidance information system has been unable to meet the safety protection needs of modern buildings.
In order to ensure the correct evacuation and guidance of survivors, the intelligent evacuation guidance information system adopts a series of intelligent designs, each with security monitoring facilities and equipment to guide the correct evacuation route at any time, and at the same time, the integrated system integrated equipment management mode links various information The safety management system and security facilities coordinate to complete the evacuation task, creating more escape opportunities for survivors.
Overall function design
The intelligent evacuation guidance information system effectively solves the problems of difficult maintenance of individual lamps and large fire blind spots in the past. In the intelligent evacuation guidance system, the system can automatically detect whether the lamps are damaged, and display the fault type and location on the host display. In the form of audible and visual alarms, the staff are reminded to perform maintenance, thereby improving the reliability of emergency lighting. In addition, the intelligent evacuation guidance system adopts multifunctional evacuation indicator lights, and cooperates with voice, strobe, two-way adjustable, visual continuous flashing and other functions to correctly guide the sight and hearing of the survivors and help them escape. The evacuation guidance system and the FAS system linkage form, combined with the FAS to select the fire plan, adjust the direction of the evacuation guidance lamps, so that the purpose of safe and fast escape can be achieved.
System elements
As the core of the evacuation guidance system, the control host implements centralized management of all emergency signs through the communication module. And it is linked with the FAS system to make the evacuation guide indicator automatically adjust the direction of the fire scene in accordance with the situation of the fire, so that fire and smoke escape can be realized, and it can cope with large-scale buildings with large crowds and complicated passages. Set up the host of emergency lighting in the fire control center, and the status of each indicator can be displayed on the host. The sound and light alarm system is linked with the FAS system to execute the linkage plan. The voice indicator is installed at the exit position at the end of the channel, and the lamp has a voice function, and different prompt sounds are used according to different fire environments. It also has a flash frequency function, which has strong penetrating power in smoke, which is more conducive to evacuation of people.
The two-way adjustable sign light is installed in the evacuation passage corridor, which can remotely adjust the evacuation indication direction, and dynamically adjust the indication direction according to the spread of fire. It also has a flashing function. Ground-oriented light flow lamps are mainly installed in the main road. When starting, it will form a continuous flicker of optical flow. It also has the function of indicating direction adjustment. The ground-oriented optical flow lamp is set every 1m.
Information maintenance
The system can strictly control the indicator light and detect the actual situation of the indicator light in real time. In particular, frequent inspections are carried out for parts that are prone to failure, including automatic main reporting of lamp light source failures, power supply abnormalities, etc., and regular inspections of emergency conversion functions and battery capacity. It can also realize the whole system monitoring function, including all communication loops in the system. The intelligent evacuation guidance system has a self-detection function. If a fault occurs, the type and location of the fault will be displayed on the host in the form of sound and light alarms, and the troubleshooting will be carried out at the first time. The system can effectively reduce the influence of human factors, and is economical and reliable in operation, and can ensure that there are no blind spots in the event of a fire accident.
Information evacuation
The intelligent evacuation guidance system is linked with the fire alarm system, combined with the fire information collected by the fire system, and the linkage plan is correctly selected and executed. The system improves the "nearest instructions" principle of the traditional evacuation guidance system, and is based on "safety guidelines for evacuation". Once a fire problem occurs, it can escape the fire scene in a more timely and safer manner. Its main advantages are:
â‘ Safety. The intelligent evacuation guidance system transforms the "nearby guidance" into the "safety guidance" form, so that the fire emergency lights in the evacuation guidance system are not independent and enclosed individuals. Based on the fire alarm information, the evacuation route plan is proposed in conjunction with Evacuation guidance is safer.
â‘¡Accurate. The intelligent evacuation guidance system adopts high-level voice guidance, low-level evacuation lighting guidance, two-way adjustable indicator lights, and continuous ground light flow guidance signs, which strengthen the escape guidance of personnel from many aspects to ensure that more people evacuate from the fire scene. For information on the fire scene, all lamps are adjusted under the control of the host to ensure that all evacuation guidance signals are consistent. Furthermore, the daily maintenance function of the intelligent system can ensure that each indicator can operate normally, avoid indicator failure or unreasonable design, and make up for the blind spots of traditional evacuation guidance systems.
③Rapidly. In the event of a fire accident, people's hearts are very panicked, and their behavior is determined by their physiological reactions and natural psychological factors. In the fire scene, there are certain commonalities in the behavior of escaped personnel, namely, blind obedience and phototropism. Among them, phototropism means that people in the dark, especially in an environment where they can’t distinguish their directions, can’t wait to move towards the light, even if it is a weak light. Blind obedience is when a fire accident occurs, because personal statements are threatened, many people lose their judgment and will follow as long as someone calls or runs. The intelligent evacuation guidance system can reduce people's panic and make people escape more orderly through auditory and visual guidance.
Modern buildings are built higher and higher, and the factors to be considered are more complicated. In the event of a fire or other special incidents, the correct evacuation and guidance of personnel and gaining golden time to escape from the scene must be the first consideration. In recent years, the company has been continuously serving various types of security, system integration and information security enterprises. It has been found that with the more popularization of intelligent buildings and the integration of equipment management, these types of products are becoming more and more relevant, and are no longer in the past. It belongs to security protection, and system integration belongs to system integration. Instead, an enterprise will undertake multi-faceted business together. The intelligent management system will be laid during the early architectural design and construction. Therefore, the qualifications of security, system integration and information security are also It is the mainstream trend for enterprises to occupy the high ground of the industry to be operated in a unified manner by large enterprises and handle multiple qualifications together.
