In recent days, LHB900, one smart neighborhood/commercial site solution previously released by China Security & Fire IOT Sensing (Shenzhen) Co., Ltd (hereafter referred to as “CSFIS”) was awarded with several honors such as “Excellent Industrial Solution” for Smart Building under the theme of “Safety Construction” held by China Security & Protection Industry Association and “Top 10 A&S Security Products 2016”. 

Since this solution was released, CSFIS has been following up user demand and focusing on technical innovations to make continuous improvement so as to keep this solution updated with the times. Today, we will explain LHB900 smart building solution with details. 

In recent years, due to incorporation of ecological and energy saving ideas, smart building has been attached high importance by governments. With the gradual implementation of national policies and continuous promotion of new urbanization plan, smart building field has come to a golden age. However, smart building has a long history in China. Regarding about its basic functions, large scale public building’s smartness has been popularized. Many newly built office buildings and commercial buildings in large and middle sized Chinese cities are already smart ones, which means that public building smartness has turned to be the standard setting for modern building. 

Due to large area and the large number of people visiting such buildings, the area required to be protected is too large and too specific, so the manufacturing cost and human cost for whole anti-theft alarming system is quite high. Smart building contains many security systems running independently and incompatibly. These factors lead to the pitiful fact that smart building is not well developed in China. Poor stability, low function efficiency and not uniform smartness level are the problems criticized all the time. 

Facing the status and existing problems of smart building, CSFIS has released the totally improved alarming solution, LHB900, a bus-type alarm system, intended for three purposes, i.e., easy for united management, simple construction and openness. This system can completely realize visualized programming and many innovative functions such as dividing protected areas into different zones, global protection through a visualized map, fast action with alarm, thereby making the building smarter and easier for management. 

1. Large covered area, easy for construction and wiring 

LHB9000 is a large bus anti-theft alarming system, supporting 240 protection modules and 248 partition keyboards The protection modules that could be programmed include: No. 1 to No. 8 on the main board, No. 9 to No. 248 on the extended module. As many as 31,248 protection modules could be connected to keyboards. After calculation, we haven noted that one main unit of this system can support up to 31,496 protection modules. Two-wire bus approach is used to expand this system. The actual communication distance controlled by one-way bus is 2,600m and 5,200 m for two-way bus (repeater may be used for longer distance). There are several types of expanded equipment, such as main control keyboard DK904, sub-control keyboard DK903, expanded LHB9000-Z8 for 8 protection modules, expanded  LHB9000-Z1 for 1 protection module, expanded LHB9000-Z2 for two protection modules and single protection module with one output LHB9000-Z1R1. 

LHB9000 bus alarming system could have 16 basic partitions and 248 keyboard partitions. The former may be either independent partitions or sub-partitions shared by public ones. Sub-partition keyboards could be controlled by superior keyboard. For example, one DK904 main-control keyboard could control as many as eight DK903 sub-control keyboards. 

LHB9000 bus alarming system adopts tree-shape wiring, supports optical fiber transmission and makes construction easier. This system could also be connected to monitoring, building intercom and door access system, etc., thereby managing peripheral protection and indoor protection simultaneously and showing strong compatibility. This system can be connected to administration center through RS232, TCP/IP and telephone cable, forming a regional security network to alarm and treat various dangerous within such region. 

2.Strong and rich functions, timely action with alarm 

LHB9000 alarming main unit is used together with C9000 management software whose public interface contains menu, tool, user structure tree, main view and real-time alarming events among others and can clearly show different kinds of information. The main unit’s name, IP address and ports could be configured. It also supports visualized programming, realizing different protection modules, each of which corresponds to a certain output, therefore forming a large alarming management system. Additionally, the management software system can administer many main units, each of which is displayed independently in the tree-structure. C9000 system can be synchronized with main unit status in real-time manner to display current event information. Functional operations on main unit such as protection arrangement/removal, by-pass and parameters could be done through this software. It is also possible to check and manage protection zone structure, user information and event record. E-map output and voice alarm area also available when alarm is output through the main unit. 

Timely and accurate smart detection 

LHB9000 alarming system can monitor the status of front-end detector (alarming, damage, low power, communication failure) in real time manner and set functions and parameters for detection at any time. 

First, verify tamper alarming. In real test, in order to confirm the timeliness of the main unit, tester removed one of wires from the main unit, the main unit gave alarm at once, while alarm information was displayed on software interface, hinting administration center to handle the problem at once. Next, simulate short circuit failure. The alarm was also very timely and accurate. When alarm receiving center is busy or telephone line is at fault, this system can record 48 events and report such information when communication is recovered. 

Private protocol can prevent interference 

LHB9000 system is connected to wireless protection areas through Horn’s RF protocol, which can effectively prevent the interference from other wireless signals. And when many detectors alarm at the same time, this system can receive and correctly identify different alarms without signal block due to interference. 

E-map’s action with alarm 

C9000 management software is equipped with e-map function. Corresponding e-map will be displayed when alarm occurs or user handles relevant alarm record. This e-map could be imported according to user’s practical needs, thereby greatly increasing operability of human-machine interface. 

In real test, the management software imported map at first, and added detector into the map. When alarming main unit and detector work normally, after the detector was triggered, main unit gave alarming signal at once and corresponding information was displayed on the e-map at once. The whole process took a very short time. When several detectors were triggered, management center showed the last alarming address, but at the same time, all the detectors being triggered were displayed on alarming records to-be-handled. 

System backup 

C9000 management software can automatically record system events, operation records and registration information with respect to the system. With this system, it is also possible to search historical records, backup historical data and recover data, etc. 

3. System application situation 

Safety is the first requirement for commercial users. Periperal security system is responsible for life and property safety of a company. LHB9000 alarming system is a solution intended for smart building anti-theft alarming. In this test, we have verified smart neighborhood solution, commercial building solution and smart park ant-theft alarming solution provided by CSFIS. 

Smart neighborhood solution can provide security for periperal region by connecting active IR detector or electronic fence to protection module. Common residential user can control the system through the LCD/LED partition keyboards installed in his/her neighborhood. For villas, you can install LED keyboards in the second and third floors to control them separately and install LCD partition keyboard in the first floor to control all the anti-theft alarming devices installed in the house. Every house's partition keyboard is connected to main unit by bus system while main unit sends data to administration center through RS232 series port or optical fibers. When the neighborhood is relatively large, you can increase main unit and a network module and report data to administration center through ICP/IP network. 

Regarding about commercial building solution. Users need to control their own devices independently, while the security in public area is assumed by property management company. Each user installs one LCD partition keyboard or LED partition keyboard to control its own device while the LHB9000-Z8 is used to connect all public areas which are controlled by administration center. 

Regarding about smart park solution, electronic fence system or active IR detector is used as the front-end device which is connected to administration center together with main unit through LHB9000-Z1, LHB9000-Z2 or LHB9000-Z8. 

In conclusion, LHB9000 system has the following characteristics: 

1. Long transmission distance: one-way distance is 2600m and the total distance of two-bus communication is 5,200m.

2. Large capacity: one main unit supports 31,496 protection modules.

3. Visualized programming, and easy management: C9000 software could be synchronized with main unit and manage several main unites at the same time.

4. Authority administration: this system supports four -level control, 248 main-control or sub-control operations, and independent or uniform protection arrangement/removal.

5. Streamlined equipment: three transmission approaches, i.e., telephone line, series port or TCP/PI
