Product Description:

1. Application

 During construction of high-rise buildings, high efficient and reliable communication between construction lifter passengers and the lifter cage driver is very important.To make the lifter run more efficient and make the communication between lifter passenger and operator more reliable, this system is designed by our company for such needs.

2. Specifics


Wireless technology is used for the communication between the host and pagers. The host applies micro processing chip,which can automatically detect calling signals and avoid the comflicts due to multiple floor pagers send the calling signal simultaneously.It has very friendly operating interface. Any passenger on whatever floor can send signal through the pager, and the host installed in the lifter cage driving room will show the calling floor number, then the operator will drive the lifter cage to the corresponding floor, which hugely improves working efficiency of the lifter. This system applies wireless alarm frequency band,frequency-stabilizing and anti-cochannel interference technology, which ganrantees working stability, long distance communication and anti-interference.

3. Composition

Each system composes two displaying control units(named Host) and dozens of calling switch boxes (named Pagers, maximum 63 pieces so far). Each host is installed on the control panel in the lifter cage driving room, and the pagers are installed on each floor correspondingly. All pagers are powered just by dry batteries which makes power source wiring not necessary, very easy to install and use.

 Wireless communication technology is adopted between hosts and pagers. No need to setup wiring for signal transmission which makes the installation

piece of cake.

Q:How do the welding parts in the welding drawings of the machine parts indicate the technical requirements of the drawings?
The whole circle of the triangle is welded as an angle weld, and the other is the outer circle with the same diameter as the two, so the butt joint is better to open the groove. Welding, for V type welding seam, and, technical requirements are generally, welding firm, no defects, welding smooth grinding, cleaning welding slag splash
Q:What are the sectors of machine building and parts processing?
Industry to classify, it is not very strict. For example, the insurance industry, mining, energy, food, hotels, real estate services industry, garment industry, advertising industry, aerospace, aviation, chemical, chemical, construction, health care, education, training, computer, metal smelting, fire, police, soldiers, accounting, beauty, body, media, publishing, wood, paper retail, wholesale, agriculture, tourism, justice, lawyers, sports, sports, arts, entertainment, medical, art, design, banking, finance, Internet, music, dance, postal, courier, transport, consulting services.
Q:What are the mechanical drawing software?
The plane is mainly CAD and CAXA, there are some non mainstream mechanical engineer what, mainly engaged in your spare parts of machinery industry, roughness, form and position tolerance requirements, recommendations for CAXA, which symbols are readily available, there are standard parts library, mechanical symbols library etc..
Q:Building materials, equipment, components and fittings products must have "three certificates" is what cards?
Three is a business license, certificate of product quality, product quality inspection certificate. Business license is the legal provisions of some industries must be licensed, and handled by the competent department of the operating permit, such as tobacco monopoly license, drug business license, business license and other dangerous chemicals.
Q:How are buildings, installations and materials divided?
Provisions on the division of equipment and materials for engineering construction? [answer] the division of equipment and materials in engineering construction is directly related to the reasonable division of investment structure, budget preparation and calculation of construction output value. In order to reasonably determine the project cost, strengthen the investment in the process of construction and management, the equipment and materials in the engineering construction is unclear, especially the universal controversial common problems and put forward the principle of division of fifteen copies of "national unified installation project budget quota" of the equipment and materials are divided, the provinces, autonomous regions and municipalities directly under the central government and the relevant departments of the State Council, the Department should be combined with the local situation, formulate rules for its implementation, and report to the Ministry of construction for the record.
Q:Where are the mechanical pressurization air supply facilities set up?
The purpose of setting up a mechanical pressurization air supply smoke prevention system is to provide evacuation routes and shelters without smoke interference in the event of a fire in the building. Therefore, in the closed door, pressing position, and the fire floor must maintain a certain pressure difference, the position of the air pressure value is a relative positive pressure); at the same time, in the open part of the pressure when the door can have enough air velocity in the opening section, to effectively prevent the intrusion of flue gas, the safety of personnel ensure evacuation and refuge.
Q:Construction Engineering, moving equipment and stationary equipment, respectively
2. Static equipment: reaction equipment (code R). Such as reactor, reaction kettle, decomposition pot, polymerizer, autoclave, converter, digester, steam ball, sulfonation pot, gas producer and so on. Heat exchange equipment (code H). Such as tubular waste heat boiler, heat exchanger, evaporator, condenser, cooler, heater, sterilization pot, water jacket, etc. for dyeing dryer, steamer, cooker, gas preheating. Separation equipment (code S)
Q:What are the main functions of construction equipment monitoring system?
This belongs to information management engineering. The control part is the "heart" and "brain" of the whole system. It is the command center to realize the function of the whole system. The control part is mainly composed of the main console (some systems also have a secondary console). The main function of the total console: video signal amplification and signal distribution, image correction and compensation, image signal and image signal (including switching or voice signals) record, cameras and auxiliary components (such as camera, PTZ, shield) control (remote control) and so on.
Q:What functions should be achieved in mechanical structure design?
Mechanical structure design plays an important role in mechanical design. This chapter mainly discusses the characteristics, steps and mode of thinking of mechanical structure design. The working principle and design requirements of the machine assembly is a major factor in determining the structure and shape of the parts, followed by the selection of materials, manufacturing process requirements, which has the advantages of good manufacturability (processing and assembly). In addition, the perfection of the structure and shape of the parts has a great influence on the strength and stiffness.
Q:What is the difference and connection between equipment manufacturing and machine building?
In accordance with the standards of classification, including metal products, general machinery manufacturing, machinery manufacturing, transportation equipment manufacturing, electronic and communication equipment manufacturing industry, electrical machinery and equipment manufacturing, instrumentation and office machinery manufacturing seven deducted 186 small consumer related manufacturing industry after class. Equivalent to the European countries referred to as "capital goods manufacturing", that is, we often say "the production of means of production industry."".
