Why hotels should install smart systems?<\/mark><\/h2>
<\/div>
  • Enhance customer experience: The smart hotel system enhances the customer experience by intelligently controlling equipment such as hotel room lights, curtains, air conditioning, and music.<\/li>\n\n
  • Reduced operating costs: the smart hotel system can reduce the hotel's energy costs, labor costs and so on.<\/li>\n\n
  • Improve management efficiency: The smart hotel system can quickly complete customer check-in registration, check-out checkout and other operations to improve the management efficiency of the hotel.<\/li>\n\n
  • Increase customer stickiness: smart hotel systems can provide more personalized services and increase customer stickiness.<\/li><\/ul>

    \u25cf<\/mark> The following article focuses on the hotel room control system with LZBUS as the core.<\/mark><\/p>

    <\/div>

    What is the LZBUS single bus system??<\/mark><\/h2>
    <\/div>

    LZBUS bus is a long-distance master-multiple-slave single-wire transmission bus, and the system communicating by LZBUS bus can be called LZBUS system.LZBUS system consists of a host and a number of nodes, and the cable thickness is not the same as the communication distance is not the same, and the communication distance of a 1-square-millimeter cable can be more than 1500 meters.<\/p>

    The external wiring of the LZBUS bus consists of the power line VBUS, the signal line S, and the ground line GND. In the case of low load currents on the system bus (<2A), the nodes can draw power from the bus, i.e., only two wires (GND, S) are needed for communication, and the nodes can be connected via a bridge stack, which can be used to make the communication non-polar, i.e., S, GND can be used regardless of the polarity.<\/p>

    If the system load current is large, you can use the three-wire system, the load current of the entire system can be done more than 10A, so that each node does not have to supply power individually, and it is convenient for engineering wiring.<\/p>

    \u25b6 LZBUS system communication characteristics<\/h3>
    <\/div>

    The LZBUS system adopts a master-multi-slave mode (also supports multi-master-multi-slave), and collects the data of each node or controls the switching output of the node by the way of the host to the node round searching.<\/p>

    When performing data acquisition, the LZBUS host can acquire data from up to 16 nodes with neighboring logical addresses in a single command frame. However, when the system is using two-wire communication, it is recommended to collect node data from up to four neighboring logical addresses at a time.<\/p>

    <\/div>

    Application example 1<\/mark>–LZBUS+Wireless Based Digital Transmission Networking Solution<\/mark><\/h4>
    <\/div>
    \"\"<\/figure>
    <\/div>

    The system consists of 4G, LZBUS bus (both master and slave), and wireless nodes;
    LZBUS communicates with 4G\/Ethernet through the serial port, the master station communicates with each slave station through the two-wire and each slave station is hooked up to a wireless digital transmission module, and communicates with the wireless nodes governed by this slave station through the wireless module; each slave station can communicate with the wireless nodes governed by the address identification method;
    If there is a communication overlap area between the wireless nodes governed by two neighboring slaves, it is possible to set the wireless nodes between different slaves to operate at different frequencies so that, kind of even if the neighboring slaves initiate queries to the governed module at the same time, no wireless conflict occurs.<\/p>

    \u25b6 Comparison of LZBUS performance with other buses<\/h3>
    <\/div>
    • The LZBUS bus supports multi-master and multi-slave buses.<\/li>\n\n
    • The LZBUS bus supports bulk reads and writes, theirs doesn't<\/li>\n\n
    • We are more stringent in our anti-interference and safety measures for the LZBUS bus.<\/li>\n\n
    • The system does not need to be re-powered to recognize when there is a replacement node, supports automatic identification, simple maintenance<\/li><\/ul>

        \u2726 Introduction to the stand-alone hotel room control system<\/h2>
        <\/div>

        Stand-alone room control system is now the most used room control system on the market, it is understood that the vast majority of four-star hotels and some five-star hotels and three-star hotels are installed such systems.<\/p>

        The reasons are summarized in the following two points:
        \u2776 The stand-alone room control system is inexpensive and can meet the needs of most hotels.
        \u2777 Because its system is a stand-alone version, it does not need to be connected to the network with other manufacturers' equipment, and is easy to install, with stable and reliable system performance.<\/p>

        \u22c6 Introduction to the main functions of the stand-alone boards<\/h3>
        <\/div>
        • Centralized weak light control:
          Adopting home-style centralized light control makes switching lights on and off more convenient. When multiple lights are turned on, the master off button can be used to turn off all lights and all controlled outlets with one click.<\/li>\n\n
        • Bathroom fan timer switch with automatic sensing:
          The light in the bathroom can be optional infrared detector sensor light, which turns on automatically when someone is there, and the fan turns on at the same time (this piece is optional). The fan has the function of timed on and delayed off.<\/li>\n\n
        • One-piece door display:
          The door display integrates the door number, doorbell switch, please do not disturb, please clean, please wait for the function of indicator lights and switches, when the guest presses the do not disturb button in the room, the doorbell does not work. When the guest presses the Please Wait in the room, the Please Wait indicator light on the door display is on, and when the guest presses the Please Clean button in the room, the Please Clean indicator light on the door display is on.<\/li>\n\n
        • Air conditioning control.
          You can use a combination of wall temperature control switches and terminal intelligent control to control the indoor temperature and coil fans, which are automatically in a low-speed energy-saving state after guests leave the room.<\/li><\/ul>

          \u2726 Introduction to Networked Hotel Room Control System<\/h2>
          <\/div>

          Room control system is a network room control system based on Ethernet communication. The system uses TCP\/IP communication and can realize the function of monitoring and managing the status and information of hotel rooms directly on the existing network integrated wiring of the hotel.<\/p>

          The whole system includes two parts: centralized management platform software of upper computer and intelligent room control hardware terminal. The database of centralized management platform can use MS SQL Server or Oracle DB Server, which makes the system stable and reliable.
          The room control system integrates intelligent lighting control, air conditioning control, service control and management functions, with intelligent, networked and standardized features.

          Networking version is based on the function of stand-alone board, increase the function of networking with the guest room department or the front desk, the increase of networking function can make the guest's SOS distress signal, please clean up the signal, check out the signal, ordering the signal, please don't disturb the signal, someone or no one signal, the indoor temperature signal transmission to the relevant departments, so as to more increase the comfort, safety and convenience of the guest's stay.<\/p>

          Air conditioning control, in addition to the stand-alone version of the function, the hotel front desk can be in the guests stay in the hotel through the network to send control signals from the room control terminal to control the air conditioning to set the room temperature in advance.
          LZBUS module can easily extend the wireless sensor network interface, wireless door magnet sensor, wireless pyro infrared sensor, wireless temperature and humidity sensor, physiological parameter monitoring system (sleep quality, etc.) and other inconvenient wiring or temporary increase in the sensor into the system unified management.<\/p>
