Description

Technical Field

[0002] Property management refers to the activities of the owners jointly managing the common parts of the separate buildings and the common buildings, places and facilities within the building area, or entrusting property service companies or other managers to manage the buildings, facilities, equipment, places and venues shared by the owners. The Property Law stipulates that owners can manage their properties themselves or entrust property service companies or other managers to manage them.

[0003] With the progress and development of society, the management work of all walks of life tends to be standardized, sustainable and computerized.

[0081] AI property equipment and facility model calculation and analysis terminal 2 includes:

[0082] The real-time monitoring unit 21 for security, power supply and water supply facilities is used to monitor the abnormal operation management platform 1 for property equipment and facilities, obtain the facility operation feedback signal information and real-time property equipment and facility change information of the abnormal operation management platform 1 for property equipment and facilities, and compare the facility operation feedback signal information and the real-time property equipment and facility change information with the preset facility operation feedback signal setting value and the preset real-time property equipment and facility change setting value, respectively, to obtain the status data of the abnormal operation management platform 1 for property equipment and facilities.

[0083] The set value of the facility operation feedback signal is expressed as:

[0112] Property equipment and facility zigbee signal moderator 42 includes:

[0113] The zigbee signal modulation unit 421 is used to receive the zigbee signal of the property equipment and facilities, demodulate the zigbee signal of the property equipment and facilities, and obtain a data packet containing the measurement data of the security, power supply and water supply facilities.

[0114] The data packet conversion unit 422 is used to convert the data packet into a TCP / IP data packet and send it to the zigbee signal control terminal 5. The reason for converting the data packet into a TCP / IP data packet here is to meet the communication protocol between the zigbee signal control terminal 5. The specific form of the data converted can be set according to the needs.

[0115] The present invention provides an embodiment, wherein the data packet conversion unit comprises:

[0116] A model building unit, used to instantiate the data packet, determine the initial data packet object, and determine the TCP / IP model data value corresponding to the initial data packet object according to a preset reference data table and the following formula;

[0117] K=1+A*ln(3+δ*B)

[0118] Wherein, K represents the TCP / IP model data value corresponding to the initial data packet object, A represents the matching value between the preset data comparison table and the initial data packet instance, and its value is (1,10), δ represents the type value of the initial data packet, and its value is (1,10), and B represents the attribute value of the initial data packet object, and its value is (1,10);

[0119] Determine the TCP / IP model data corresponding to the value range of the TCP / IP model data value corresponding to the initial data packet object in the preset comparison data table, and construct a TCP / IP object model based on the TCP / IP model data corresponding to all the initial data packet objects;

[0120] The data packet conversion unit is used to input the initial data packet object into the TCP / IP object model to obtain the corresponding TCP / IP object, and obtain the conversion value of the initial data packet based on the TCP / IP object and according to the following formula;

[0121]

[0122] Among them, F represents the conversion value of the initial data packet, P represents the object attribute value of the TCP / IP object, and its value is (1,10), e represents the natural constant, and its value is 2.72, τ represents the model characteristic value of the TCP / IP object model, and its value is (0,1), and Q represents the type value of the TCP / IP data packet, and its value is (1,10);

[0123] Based on the conversion value of the initial data packet, a TCP / IP data packet corresponding to the initial data packet is obtained.

[0124] In this embodiment, the TCP / IP model data value corresponding to the initial data packet object can be matched to the TCP / IP model data corresponding to the value range satisfied in the preset comparison data table.

[0125] In this embodiment, the TCP / IP object model is used to realize the automatic conversion of the initial data packet object to the TCP / IP object.

[0126] In this embodiment, the matching value between the preset data comparison table and the initial data packet instance is determined by the instance feature of the initial data packet instance.

[0127] The beneficial effects of the above design scheme are: by instantiating the data packet, determining the initial data packet object, and determining the corresponding TCP / IP model data according to the initial data packet object and a specific algorithm, and constructing a TCP / IP object model based on the TCP / IP model data corresponding to all the initial data packet objects, a model basis is provided for determining the TCP / IP object, the conversion value of the initial data packet is determined based on the TCP / IP object and a specific algorithm, based on the conversion value of the initial data packet, the TCP / IP data packet corresponding to the initial data packet is obtained, the conversion from the initial data packet to the TCP / IP data packet is realized, the calling and storage of the data packet by the ZigBee signal control terminal is realized, and remote monitoring of abnormal property facilities is realized, which can improve the effectiveness and real-time nature of monitoring and facilitate the use of property management personnel.

[0128] The third data storage unit 423 is used to obtain the energy consumption value from the sensor data acquisition and preprocessing module 3, and convert it into an electrical signal for the Zigbee signal mediation unit and the data packet conversion unit to call and back up the data.

[0129] For example, the zigbee signal control terminal 5 can be a cloud data service unit, which is used to obtain and store TCP / IP data packets. After receiving the TCP / IP data packets, the data packets are parsed to obtain the usage status of the property equipment and facility abnormal operation management platform 1. The usage status of the property equipment and facility abnormal operation management platform 1 can be stored in the cloud data service unit, and can also be sent to the terminal used by the user through the cloud data service unit.

[0130] like Figure 2 FIG. 1 is a flow chart of a method for intelligently monitoring abnormal property facilities according to another embodiment of the present invention. The method comprises:

[0131] Step S1, the AI ​​property equipment and facility model calculation and analysis terminal monitors the property equipment and facility abnormal operation management platform, and obtains the facility operation feedback signal information and real-time property equipment and facility change information of the property equipment and facility abnormal operation management platform. The acquisition method and acquisition frequency here can be set according to actual needs. For example, the facility operation feedback signal information and real-time property equipment and facility change information of the property equipment and facility abnormal operation management platform are obtained at preset intervals. The property equipment and facility abnormal operation management platform can also be monitored according to control commands. For example, after receiving the control instruction sent from the sensor data acquisition and preprocessing module, the facility operation feedback signal information and real-time property equipment and facility change information of the property equipment and facility abnormal operation management platform are obtained according to the control instruction.

[0132] Step S2, the AI ​​property equipment and facility model calculation and analysis terminal compares the facility operation feedback signal information and the real-time property equipment and facility change information with the preset facility operation feedback signal setting value and the preset real-time property equipment and facility change setting value, and obtains the status data of the property equipment and facility abnormal operation management platform.

[0133] For example, the status data of the property equipment and facility abnormal operation management platform can be divided into three types, namely, operating status data that is in operation, measurement status data that is not in operation but can be run at any time, and abnormal operation status data that has stopped running. The real-time property equipment and facility change setting value can be set to two values, A and B, and the facility operation feedback signal setting value can be set to two values, C and D.

[0134] Step S2 can be refined into the following steps:

[0135] After obtaining the real-time property equipment and facility change information and facility operation feedback signal information of the property equipment and facility abnormal operation management platform, the real-time monitoring unit of the security, power supply and water supply facilities first judges the real-time property equipment and facility change information with the real-time property equipment and facility change setting value. When the real-time property equipment and facility change information is greater than or equal to B, the status data of the property equipment and facility abnormal operation management platform is obtained as operation status data; when the real-time property equipment and facility change information is greater than A and less than B, the status data of the property equipment and facility abnormal operation management platform is obtained as measurement status data; when the real-time property equipment and facility change information is equal to A, the facility operation feedback signal information is judged with the facility operation feedback signal setting value. When the facility operation feedback signal information is greater than C and less than D, the status data of the property equipment and facility abnormal operation management platform is obtained as operation abnormal status data.

[0136] Step S3, the AI ​​property equipment and facility model calculation and analysis terminal modulates the measurement data of the security, power supply, and water supply facilities, including the facility operation feedback signal information, real-time property equipment and facility change information, and status data, into a property equipment and facility zigbee signal, and sends it to the sensor data acquisition and preprocessing module. The AI ​​property equipment and facility model calculation and analysis terminal can temporarily store the measurement data of the security, power supply, and water supply facilities. When receiving the control instruction sent from the sensor data acquisition and preprocessing module, it modulates the measurement data of the security, power supply, and water supply facilities into a property equipment and facility zigbee signal according to the control instruction, and then sends it to the sensor data acquisition and preprocessing module. It can also periodically modulate the measurement data of the security, power supply, and water supply facilities into a property equipment and facility zigbee signal according to a preset time interval, and send it to the sensor data acquisition and preprocessing module.

[0137] Step S4, the multi-point signal wireless transmission base station obtains the ZigBee signal of the property equipment and facilities from the sensor data acquisition and preprocessing module and demodulates it to obtain the measurement data of the security, power supply and water supply facilities.

[0138] Step S5, the multi-point signal wireless transmission base station sends the measurement data of the security, power supply and water supply facilities to the preset zigbee signal control terminal. It should be understood that before the multi-point signal wireless transmission base station and the zigbee signal control terminal communicate and transmit, the measurement data of the security, power supply and water supply facilities need to be converted into a transmittable signal format.

[0139] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", and "fix" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
