[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figure 1 , which is a schematic diagram of the structure of a building automatic control system 100 in an embodiment of the present disclosure. The building automatic control system 100 provided in the embodiment of the present disclosure includes: a data acquisition unit 110, a data processing unit 120 and a data alarm unit 130.

[0028] The data acquisition unit 110 is used to acquire the system data of the building and send the system data to the data processing unit 120 through 433MHZ radio frequency wireless communication technology, wherein the system data includes temperature and humidity data, lighting data, elevator data, smoke data and intercom data.

[0029] In the disclosed embodiment, the data acquisition unit 110 is the front end of the system, responsible for real-time acquisition and monitoring of various system data in the building, which may include but is not limited to temperature and humidity sensors, light relays, elevator controllers, smoke sensors, and building intercoms, etc. The corresponding system data is acquired and encoded through each sensor in the system, which may include but is not limited to temperature and humidity data, light data, elevator data, smoke data, and intercom data, etc.

[0030] It is understandable that temperature and humidity data can reflect the ambient temperature and humidity conditions in the building, which is crucial to maintaining the comfort of people in the building and the normal operation of equipment; lighting data can monitor the status and energy consumption of the lighting system, help managers optimize lighting strategies and reduce energy waste; elevator data can record the operating status and location of the elevator, which helps to promptly detect and resolve elevator failures and ensure personnel safety; smoke data can detect fire hazards and provide important protection for the fire safety of the building; intercom data can monitor the communication security of the building intercom to ensure that people can communicate smoothly in an emergency.

[0031] After collecting the above system data, the data acquisition unit 110 sends the encoded system data to the data processing unit 120 through the 433MHZ radio frequency wireless communication technology. It should be noted that this communication method can penetrate obstacles in the building, such as walls, floors, etc., to ensure reliable data transmission, and the transmission distance is far enough to meet the data transmission needs of large-scale buildings. It has the characteristics of strong penetration and long transmission distance, and is very suitable for data transmission inside buildings.

[0032] It should also be noted that the sensor in the data acquisition unit 110 provided in the embodiment of the present disclosure can adopt IIC (Inter-Integrated Circuit, two-wire serial bus) and TTL (Transistor-Transistor Logic, transistor-transistor logic level) transmission methods, and the single-chip digital circuit design of the national chip, and after industrial design packaging, a low-cost sensor is formed, with an accuracy of 0.01 degrees and a humidity error of less than 2%. Using a single-chip microcomputer to open up the "drive layer" means that the interaction between the sensor and the system is more direct and efficient. The single-chip microcomputer, as the core control unit of the sensor, can realize the accurate collection and processing of sensor data. By adopting this innovative sensor design, the risk of the "black box" brought by the direct use of DDC and PLC controllers can be abandoned, and the effect of building safety control can be achieved.

[0033] Therefore, as a front-end component in the building management system, the data acquisition unit 110 provides important support for intelligent management of buildings by collecting, summarizing and transmitting system data. At the same time, the application of 433MHZ radio frequency wireless communication technology ensures reliable data transmission and stable operation of the system.

[0034] The data processing unit 120 is used to perform abnormal analysis on the system data, determine the abnormal data, and send the abnormal data to the data alarm unit 130.

[0035] Understandably, the data processing unit 120 is the core of the system, responsible for processing and analyzing the data received from the data acquisition unit 110. After receiving the encoded system data sent by the data acquisition unit 110, the encoded system data is first parsed, and the encoded system data is restored to the original system data for subsequent analysis and processing. After the parsing is completed, the data processing unit 120 will conduct a comprehensive comparison, trend analysis or pattern recognition of each system data through some thresholds, rules and other standards, and accurately identify those data that deviate from the normal range or do not conform to the expected pattern, that is, abnormal data. The identified abnormal data is sent to the data alarm unit 130 for further processing.

[0036] Exemplarily, the collected temperature and humidity data are compared with the corresponding temperature and humidity thresholds. If they are higher than the temperature and humidity thresholds, it means that the corresponding temperature and humidity data are abnormal data. The subsequent data processing unit 120 can achieve constant temperature and humidity by adjusting the power of the air conditioner in the building in real time; the collected lighting data are compared with the corresponding switch control rules to determine whether they comply with the switch control rules, that is, whether the lights are on or off within the time period specified by the switch control rules. If not, it means that the corresponding lighting data are abnormal data. The subsequent data processing unit 120 can meet the preset switch control rules by uniformly controlling the on and off of all lighting circuits.

[0037] Therefore, the data processing unit 120 plays a vital role in the system. It provides a strong guarantee for the stable operation of the system and the accuracy of the data through in-depth analysis and abnormality identification of system data.

[0038] The data alarm unit 130 is used to display system data and generate alarm prompt information according to abnormal data.

[0039] Understandably, the data alarm unit 130 is the backend of the system, which may be a host computer or other device, and the data processing unit 120 is linked to the host computer through a serial port to perform data interaction processing.

[0040] The data alarm unit 130 is mainly responsible for displaying the system data received from the data acquisition unit 110. A dashboard of various data can be seen in the host computer, and it provides switch control functions, data statistics functions, data analysis and recording functions, etc. Users can conduct real-time monitoring through the data alarm unit 130 to fully understand the operating conditions of various facilities in the building.

[0041] In addition, the data alarm unit 130 can also generate alarm prompt information according to the abnormal data sent by the data processing unit 120. These prompt information may include the type of abnormal data (such as high temperature, abnormal lighting), location (such as a certain floor, a certain room), severity (such as minor, serious), etc. This design enables users and systems to quickly locate the problem and take corresponding countermeasures, thereby effectively avoiding potential safety hazards and losses.

[0042] In actual applications, the data alarm unit 130 may issue an alarm prompt in various ways such as sound, light and electricity. For example, when abnormal data is detected, the system may issue a harsh alarm, flash an indicator light, or pop up a striking alarm window to attract the user's attention. At the same time, the data alarm unit 130 may also send the alarm information to the mobile phone, email and other communication devices of the relevant personnel to ensure that the information can be conveyed to the relevant personnel in a timely manner so that they can respond and handle it quickly.

[0043] The building automation system 100 provided in the embodiment of the present disclosure realizes real-time monitoring and intelligent management of various facilities and data in the building by integrating data acquisition, processing and alarm functions, and adopts modified 433MHZ radio frequency communication technology to realize data transmission and communication between units, eliminating the difficulty and cost of wiring layout.

[0044] In one embodiment, if Figure 2 As shown, the data acquisition unit 110 includes: a temperature and humidity sensor 111, a light relay 112, an elevator controller 113, a smoke sensor 114 and a building intercom 115.

[0045] The temperature and humidity sensor 111 is used to collect temperature and humidity data of the building, encode the temperature and humidity data, and send the encoded temperature and humidity data to the data processing unit 120, wherein the temperature and humidity data includes temperature information and humidity information.

[0046] Understandably, the temperature and humidity data of the building are collected by the temperature and humidity sensor 111, and the encoded temperature and humidity data are sent to the data processing unit 120 via 433MHZ. For example: the current temperature value is 23.5 degrees, and the current humidity value is 55%. The encoding can provide data accuracy by adding a frame header and a frame tail, for example: FF 00EB 37FE hexadecimal string, where FF is a frame header flag, FE is a frame tail flag, 00 is the high eight bits (hexadecimal) of the temperature value, EB is the low eight bits (hexadecimal) of the temperature value, 00 is the high eight bits (hexadecimal) of the humidity value, and 37 is the low eight bits (hexadecimal) of the humidity value.

[0047] The lighting relay 112 is used to collect lighting data of each lighting circuit in the building, encode the lighting data, and send the encoded lighting data to the data processing unit 120, wherein the lighting data includes lighting status information.

[0048] It can be understood that the hospital's total lighting circuit is divided into multiple separate lighting circuits according to department or area locations, and the lighting status information in each lighting circuit is collected through the lighting relay 112. The lighting data is converted into a format suitable for transmission using a specific encoding algorithm, and the encoded lighting data is sent to the data processing unit 120 via 433MHZ radio frequency communication technology.

[0049] The elevator controller 113 is used to collect elevator data of each elevator in the building, encode the elevator data, and send the encoded elevator data to the data processing unit 120, wherein the elevator data includes real-time position information, movement direction information and working status information.

[0050] Understandably, the elevator controller 113 collects the elevator data of each elevator in the building, including real-time position information, movement direction information and working status information, and encodes the elevator data and sends it to the data processing unit 120 through 433MHZ radio frequency communication technology. The real-time position data of the elevator is: 1F, 2F, 3F, etc., and the working status data is: RUN (normal operation), ERROR (fault error), BUSY (task in progress), etc. For example, the format of the elevator data of a certain elevator after encoding is: "Elevator1: RUN, NOW=2F, Uping", where Elevator1 represents the elevator number, RUN represents that the elevator is currently in normal operation, NOW=2F represents that the elevator is currently located at 2F, and Uping represents that the elevator is going up.

[0051] The smoke sensor 114 is used to collect smoke data of the building, encode the smoke data, and send the encoded smoke data to the data processing unit 120, wherein the smoke data includes smoke status information.

[0052] Understandably, smoke data of the building, including smoke status information, is collected through the smoke sensor 114, and the smoke data is encoded and sent to the data processing unit 120 through the 433MHZ radio frequency communication technology. For example, the smoke sensor 114 in the locker room detects an abnormality (if the smoke sensor 114 is an ion type, a large number of solid particles and liquid particles are detected as abnormalities, and if the smoke sensor 114 is a photoelectric type, the smoke concentration exceeds a certain threshold value, which is abnormality), and an encoded string "Changeroom1. Smoke Detector found Smoke" is generated, where Changeroom1 represents the locker room number, and Smoke Detector found Smoke represents that the smoke detector finds smoke.

[0053] The building intercom 115 is used to collect intercom data of the building and send the intercom data to the data processing unit 120 .

[0054] Understandably, the building intercom 115 collects intercom data of the building, including call records (call time, call duration, identity information of both parties between intercom users), call records (call requests initiated by users, call objects, call time, whether the call is connected, etc.), system status (operating status of the intercom system, network connection status), etc., and sends the intercom data to the data processing unit 120 via 433MHZ radio frequency communication technology.

[0055] Therefore, the system collects system data through various sensors and uses 1-to-N (i.e., one data processing unit 120 simultaneously receives data from multiple sensors) 433MHZ radio frequency wireless communication technology. This communication mode greatly improves the flexibility and scalability of the system, does not rely on the network, and has the advantage of no wiring.

[0056] In one embodiment, if Figure 3 As shown, the data processing unit 120 includes a temperature and humidity data analysis module 121 .

[0057] The temperature and humidity data analysis module 121 is used to receive the encoded temperature and humidity data, and analyze the encoded temperature and humidity data to obtain the temperature information and humidity information of the building.

[0058] Preferably, after the temperature and humidity data analysis module 121 receives the encoded temperature and humidity data, it parses the encoded temperature and humidity data. For example, when the hexadecimal string "FF 00EB 37FE" is received, the high eight bits 00 and the low eight bits EB of the temperature are converted to decimal to obtain 235, which is then divided by 10 (because the accuracy is 0.01 degrees) to obtain the actual temperature value of 23.5 degrees. The high eight bits 00 and the low eight bits 37 of the humidity are converted to decimal to obtain 55, which is the actual humidity value.

[0059] The temperature and humidity data analysis module is also used to determine whether the temperature information is greater than a preset temperature threshold and whether the humidity information is greater than a preset humidity threshold. When the temperature information is greater than the preset temperature threshold and / or the humidity information is greater than the preset humidity threshold, the temperature and humidity data are determined as abnormal data.

[0060] Understandably, after the temperature information and humidity information are parsed and obtained, they are compared with the corresponding preset temperature threshold and preset humidity threshold, respectively. When any one of the two exceeds its corresponding threshold, it is determined to be abnormal data.

[0061] Therefore, the data processing module not only has the ability to analyze data, but also can automatically determine whether the temperature and humidity data are abnormal based on the preset temperature and humidity thresholds. This intelligent anomaly detection function helps to promptly discover and deal with potential environmental problems, thereby avoiding possible losses.

[0062] In one embodiment, if Figure 3 As shown, the data processing unit 120 further includes a light data analysis module 122 .

[0063] The light data analysis module 122 is used to receive the encoded light data and analyze the encoded light data to obtain the light status information of each light circuit.

[0064] Preferably, after receiving the encoded light data, the light data analysis module 122 analyzes the encoded light data to obtain light status information corresponding to each light circuit.

[0065] The lighting data analysis module 122 is also used to determine whether the lighting status information of each lighting circuit meets the preset switch control rules at the current time. When there is a lighting circuit whose lighting status information does not meet the preset switch control rules at the current time, the lighting data is determined as abnormal data.

[0066] Understandably, after parsing and obtaining the light status information of each light circuit, the light status at the current time is compared with the preset switch control rule. If the current time is within the on time period specified by the preset switch control rule, but the light circuit is actually off, or vice versa, it is determined that the state of the light circuit does not conform to the preset switch control rule, that is, it is determined as abnormal data.

[0067] Therefore, the lighting data analysis module 122 not only has the data analysis capability, but also can automatically determine whether the lighting status information of each lighting circuit complies with the rules according to the preset switch control rules. When a lighting circuit that does not comply with the rules is found, the module can immediately mark it as abnormal data, so as to timely discover and deal with potential lighting problems.

[0068] In one embodiment, if Figure 3 As shown, the data processing unit 120 further includes an elevator data analysis module 123 .

[0069] The elevator data analysis module 123 is used to receive the encoded elevator data and analyze the encoded elevator data to obtain the real-time position information, movement direction information and working status information of each elevator.

[0070] Preferably, after receiving the encoded elevator data, the elevator data analysis module 123 parses the encoded elevator data. For example, when receiving the string "Elevator 1: RUN, NOW = 2F, Uping", it can be parsed that the elevator is numbered 1, the current operating status is normal, the current position is 2F, and it is ascending.

[0071] The elevator data analysis module 123 is also used to determine whether the movement direction information is abnormal based on the real-time position information of each elevator, and to determine whether the working status information of each elevator is in an error state. When there is an elevator with abnormal movement direction information and / or an elevator with an error state of working status information, the elevator data is determined to be abnormal data.

[0072] Understandably, after parsing and obtaining the real-time position information, movement direction information and working status information of each elevator, it is determined whether the movement direction information is abnormal according to the real-time position information of each elevator, and whether the working status information of each elevator is in an error state. For example, if the elevator state is RUN and the movement direction is Uping, but the current floor is lower than the floor recorded at the last moment, this may indicate that the elevator movement direction is abnormal; if the parsed state is ERROR, it means that the current working status information is in an error state, that is, it is determined to be abnormal data.

[0073] Therefore, the elevator data analysis module 123 helps to timely discover and handle abnormal situations in the system, such as abnormal elevator movement direction, working status error, etc. This timely abnormality detection and processing capability can significantly improve the safety and reliability of the elevator and ensure the travel safety of passengers.

[0074] In one embodiment, if Figure 3 As shown, the data processing unit 120 further includes a smoke data analysis module 124 .

[0075] The smoke data analysis module 124 is used to receive the encoded smoke data and analyze the encoded smoke data to obtain smoke status information of the building.

[0076] Preferably, after receiving the encoded smoke data, the smoke data analysis module 124 parses the encoded smoke data. For example, if a character string "Changeroom1.Smoke Detector found Smoke" is received, it can be parsed to find that the smoke detector in locker room 1 has found smoke.

[0077] The smoke data analysis module 124 is also used to determine whether the smoke status information meets the preset smoke alarm rules. When the smoke status information meets the preset smoke alarm rules, the smoke data is determined to be abnormal data.

[0078] Understandably, after the smoke status information is parsed, it is compared with the preset smoke alarm rule. For example, if it is parsed that the smoke detector in locker room 1 detects smoke, and the preset smoke alarm rule is that smoke appears, it is determined to be abnormal data.

[0079] Therefore, through the preset smoke alarm rules, the smoke data analysis module 124 can automatically determine the severity of the smoke status information and generate abnormal data to send to the data alarm unit 130. This intelligent safety management method not only improves the safety management efficiency, but also reduces the risk of false alarms or missed alarms caused by human factors.

[0080] In one embodiment, if Figure 3 As shown, the data processing unit 120 also includes a walkie-talkie data analysis module 125 .

[0081] The intercom data analysis module 125 is used to receive intercom data, determine whether the intercom data contains abnormal calls, unanswered call requests or abnormal system status, and when the intercom data contains abnormal calls, unanswered call requests, and / or abnormal system status, determine the intercom data as abnormal data.

[0082] Understandably, the intercom data analysis module 125 can be used to analyze call records and identify abnormal calls (such as frequent calls, long calls, calls in abnormal time periods, etc.), which may indicate malicious harassment, illegal occupation of the system, etc.; analyze call records and identify unanswered call requests (especially repeated calls to the same object), which may indicate system failure or user equipment failure; monitor the operating status of the intercom system and identify abnormal situations such as frequent system offline and network instability. If any of the above abnormalities occur, they will be determined as abnormal data.

[0083] Therefore, the intercom data analysis module 125 can promptly detect and handle potential security issues such as abnormal calls, unanswered call requests, and abnormal system status, which helps prevent security incidents such as malicious harassment and illegal occupation of the system, thereby improving the overall security of the intercom system.

[0084] In one embodiment, if Figure 4 As shown, the building automation system 100 further includes a temperature and humidity control unit 140 for adjusting the temperature information and humidity information of the building.

[0085] Preferably, the temperature and humidity control unit 140 generally refers to equipment such as air conditioners and humidifiers, which are responsible for accurately controlling the temperature and humidity inside the building.

[0086] The data processing unit 120 is also used to control the temperature and humidity control unit 140 of the building according to the alarm prompt, so that the temperature information of the building reaches a preset temperature threshold, and the humidity information of the building reaches a preset humidity threshold.

[0087] It is understandable that when the alarm prompt shows that the temperature and humidity information in the building exceeds the preset threshold, the data processing unit 120 will immediately control the temperature and humidity control unit 140. Specifically, the data processing unit 120 will send control instructions to the temperature and humidity control unit 140 through the communication protocol, such as adjusting the cooling / heating power of the air-conditioning system, turning on / off the humidifier or dehumidifier, etc., so that the temperature information of the building quickly reaches the preset temperature threshold, and the humidity information also reaches the preset humidity threshold.

[0088] This intelligent temperature and humidity control method not only improves the comfort of the building, but also helps save energy and reduce emissions. By precisely controlling the environmental conditions in the building, the system can avoid unnecessary energy waste, thereby reducing operating costs. In addition, since the system can monitor and adjust environmental parameters in real time, it can also effectively prevent equipment failure or damage caused by abnormal temperature and humidity.

[0089] In one embodiment, the data processing unit 120 is further configured to control the lighting relay 112 according to the alarm prompt and the preset switch control rule, so that each lighting circuit satisfies the preset switch control rule.

[0090] It can be understood that if the alarm prompt indicates that the current time is within the open time period specified by the preset switch control rule, but the lighting circuit is actually closed, then when the data processing unit 120 sends a signal OPEN_IO_A to the secondary control unit of the lighting circuit, it represents a high level, and the driving relay is turned on. At this time, the lamps in the circuit are powered and lit; if the alarm prompt indicates that the current time is within the closed time period specified by the preset switch control rule, but the lighting circuit is actually open, then when the data processing unit 120 sends a signal CLOSE_IO_A to the secondary control unit of the lighting circuit, it represents a low level, and the driving relay is turned off. At this time, the power supply to the lamps in the circuit is cut off, causing the lamps to go out.

[0091] In this way, the data processing unit 120 can flexibly control the switch status of each lighting circuit in the building according to the preset switch control rules, thereby realizing intelligent adjustment of the lighting environment. This not only improves the comfort and energy saving effect of the building, but also makes the management of the building more convenient and efficient.
