The pager is divided into a wired pager and a wireless pager, and the wireless pager is the most widely used. According to the product technology, the wireless pager can be divided into frequency modulation technology and amplitude modulation technology. The wireless pager using the frequency modulation technology is more advanced, and the wireless pager using the amplitude modulation technology is cheap but has many disadvantages. The use of pagers is more and more widely used in many industries such as catering services, banks, administrative offices, commercial super-chains, factory sites, medical pensions, and functions are increasingly diversified.
With the continuous development of China's economy and society, people's living standards are constantly improving, and entertainment, tourism and other services have also developed rapidly. Due to the increasingly fierce competition among service industries, the timeliness of services has often become a decision. The important factors of the quality of service places, the development of enterprises depends on the concept of innovation, the service concept and the renewal of service facilities, also means the innovation and development of enterprises. Therefore, we advocate the concept of turning active services into on-demand services to create a consumption environment that “does not bother customers and not delay service†and follow the path of international service model. Therefore, an emerging service relay product— Wireless pager products have been born and are gradually recognized by Chinese consumers and businesses.
A wireless pager is an electronic device with one or more buttons that send preset information for a particular receiving unit. It can be divided into wired and wireless. The most common wired caller is the bedside pager used in hospital wards. Because the installation of wired pager must be wired, it takes time and effort, the receiving unit must be in a fixed location, and the working mode is not flexible. Shortcomings such as high maintenance and maintenance costs, and fewer and fewer applications.
The wireless pager can be roughly divided into three stages from technology and application: the first stage is mainly AM AM technology (ie: the first generation wireless pager), mainly used for smaller venues; the second stage is FM FM is the core technology product (ie: the second generation wireless pager system), the signal is stable, suitable for large-scale networking, the application industry has developed from small service places such as tea houses and cafes to large entertainment places, hotels, factories, supermarkets, Schools and banks and other industries, this stage is the fastest development of wireless pager applications; the third stage is spread spectrum frequency hopping intelligent technology, full Chinese display and all Chinese voice broadcast and development software and wireless call system combination, to achieve The wireless pager has shifted from a fixed call mode to a professional custom service, becoming the trend and mainstream of wireless pager system applications.
After 2000, wireless pagers appeared in the Chinese market. Due to their practicality and convenience, they were quickly recognized by the market. From the initial service industry to the leisure and entertainment industry, to hospitals, nursing homes, factories, supermarkets, banks, and enterprises. , government office and other applications. The pager has also evolved from the original one-touch pager to a multi-key pager, dispatcher, caller, etc.
Since AC power cord is output of high voltage electric power, there is a risk of electric shock injury, therefore, All the AC power cord must comply with safety standard to produce. AC (Alternating Current) Power cord is to transmit high voltage. It is used to drive machinery or home appliances.
