Fig. 1b is a schematic flowchart of an asset retrieval method provided in an embodiment of the present application, where the method is applied in a server, and a specific flowchart of the asset retrieval method may be as follows:

101, receiving an asset retrieval request from a terminal.

The terminal can provide an asset retrieval interface, the asset retrieval interface is provided with a plurality of first controls, and a plurality of setting parameters such as the asset to be retrieved or the information such as the spatial position to be retrieved can be set through the first controls. On the asset retrieval interface, if the second control is detected to be triggered, acquiring an interface identifier related to the second control and setting parameters of the first control, and acquiring a terminal user identifier. The second control can be related buttons such as "asset location query", "asset track query", "asset video query", "asset location name query", "location asset query", and the like. In particular, as shown in fig. 1 c. Fig. 1c is a simplified schematic diagram of an asset retrieval interface provided in the embodiment of the present application, which is only for illustration and does not limit the asset retrieval interface. The interface identifier includes identifier information of a plurality of different interfaces, where the interface identifier information includes information such as an interface ID (e.g., interface 23, interface with a serial number of 23) or an interface name (e.g., function name corresponding to the interface, or interface literal name). The end user identification comprises information used for identifying the user, such as an end user nickname, a mailbox, a two-dimensional code, a WeChat, a telephone number and the like. And the terminal generates an asset retrieval request according to the acquired interface identifier in the second control, the setting parameter of the first control and the terminal user identifier, and sends the asset retrieval request to the server. And the server receives the asset retrieval request sent by the terminal.

The asset retrieval request of the terminal can also be sent to the server in a voice mode, and the server receives the voice asset retrieval request from the terminal.

The terminal can also directly send an asset retrieval request to the server in a command sending mode, and the server receives the asset retrieval request.

The terminal can also send the asset retrieval request to the server in other manners. It should be noted that the asset retrieval request, regardless of the manner in which it is sent, carries the end user identification. The asset retrieval request transmitted in any form may be transmitted to the server via an HTTP Protocol (HyperText Transfer Protocol). The server receives an asset retrieval request.

And 102, analyzing the asset retrieval request to obtain retrieval parameters.

For example, the asset retrieval request received by the server is sent by the terminal by triggering the corresponding control. Thus, parsing the asset retrieval request to obtain retrieval parameters includes: and analyzing the setting parameters, the interface identification and the terminal user identification of the asset retrieval request to obtain retrieval parameters. The setting parameters comprise two types, wherein one type is asset identification and comprises information such as asset ID or asset name and the like; one is a location marker, which includes information such as spatial location coordinates or spatial location ranges. In some cases, the asset ID and asset name are unique, such that a unique asset can be determined by either the asset ID or asset name. In some cases, the asset ID and asset name are not unique, and a unique asset is determined by the location identification and the asset identification together. In the embodiments of the present application, an example is described in which one asset can be uniquely determined by an asset ID or an asset name. By parsing the asset retrieval request, retrieval parameters such as an interface identifier, an asset identifier, or a location identifier may be obtained.

For example, the asset retrieval request received by the server is sent by the terminal in a voice manner. Thus, parsing the asset retrieval request to obtain retrieval parameters includes: identifying voice information in the voice asset retrieval request by a voice identification method to obtain a voice identification result; extracting asset information or position information in the voice recognition result; extracting interface related information and the like according to the semantics of the voice recognition result; and mapping the asset information or the position information into an asset identifier or a position identifier respectively, and mapping the interface related information into an interface identifier. If the voice recognition result comprises the spatial position of the camera to be inquired, extracting asset information of the camera, and taking the camera as an asset name; according to the semantics of the voice recognition result, extracting the spatial position of the interface related information, namely query, and mapping the interface related information into an interface identifier so as to query the spatial position of the asset through the asset information, namely the camera A. For example, "i want to query the number of tables in the third floor", where location information "third floor" is extracted and asset information "table" is extracted; extracting interface related information 'inquiring the third floor.. the number of tables' according to semantics in a voice recognition result; and mapping the interface related information into an interface identifier so as to inquire the information of the asset 'table' through a spatial position 'third floor' and count the quantity information of the asset 'table'. For example, the database includes the interpretation information of the data access interface corresponding to each interface identifier, and the semantics in the speech recognition result is matched with the interpretation information, so as to map the interface-related information to a specific interface identifier.

For example, the asset retrieval request received by the server is sent by the terminal by way of a command. Thus, parsing the asset retrieval request to obtain retrieval parameters includes: acquiring a command corresponding to the asset retrieval request; according to the structure of the command, the asset identification or position information and the interface name in the command are extracted.

And analyzing the asset retrieval request to obtain retrieval parameters such as an interface identifier, an asset identifier or a position identifier. It is to be reminded that user parameters, such as end user identification, may also be obtained.

And 103, calling a corresponding data access interface according to the parameter type of the retrieval parameter.

The retrieval parameters include: interface identification (interface ID, interface name, etc.), asset identification (asset ID, asset name, etc.), or location identification (spatial location coordinates, spatial location range, etc.). The parameter types of the retrieval parameters are divided into two main categories: input information and interface information. The input information also includes two categories: asset identification and location identification to represent two different input information. The interface information includes an interface identification. It is noted that the input information also includes other types of information.

Specifically, when the parameter type includes an asset identifier and a first interface identifier, step 103 includes: and calling an asset position query interface according to the asset identifier and the first interface identifier. The data access interface corresponding to the first interface identifier is an asset location query interface (interface literal name). Namely, according to the asset identification, calling the function of the asset position query interface corresponding to the first interface identification.

Wherein the asset location query interface implements: and inputting the asset identification, and outputting the position information (information such as spatial position coordinates or spatial position coordinate ranges) of the asset corresponding to the asset identification by calling a function of the asset position query interface. For example, if the function corresponding to the asset location query interface is GetCoordByAssetsID, the program/module corresponding to the GetCoordByAssetsID function is called to output the location information of the asset corresponding to the asset identifier according to the input asset identifier.

Specifically, when the parameter type includes an asset identifier and a second interface identifier, step 103 includes: and calling an asset track query interface according to the asset identification and the second interface identification. And the data access interface corresponding to the second interface identifier is the asset track query interface. And calling the function of the asset track query interface corresponding to the second interface identification according to the asset identification.

Wherein, the asset track query interface implements: and inputting the asset identification, and calling a function of the asset track query interface corresponding to the second interface identification to output the motion track information of the asset corresponding to the asset identification. For example, if the function corresponding to the asset track query interface is GetTravelByAssetsID, the program/module corresponding to the GetTravelByAssetsID function is called to output the motion track information of the asset corresponding to the asset identifier according to the input asset identifier.

Specifically, when the parameter type includes an asset identifier and a third interface identifier, step 103 includes: and calling an asset video query interface according to the asset identification and the third interface identification. And the data access interface corresponding to the third interface identifier is the asset video query interface. And calling the function of the asset video query interface corresponding to the third interface identification according to the asset identification.

Wherein, the asset video query interface implements: and inputting the asset identification, and calling a function of the video query interface corresponding to the third interface identification to output video information shot by the asset corresponding to the asset identification. For example, if the function corresponding to the video query interface is GetVideoByAssetsID, the program/module corresponding to the GetVideoByAssetsID function is called to output video information shot by the asset corresponding to the asset identifier according to the input asset identifier.

Specifically, when the parameter type includes an asset identifier and a fourth interface identifier, step 103 includes: and calling an asset position name inquiry interface according to the asset identifier and the fourth interface identifier. And the data access interface corresponding to the fourth interface identifier is the asset position name query interface. And calling the function of the asset position name query interface corresponding to the fourth interface identifier according to the asset identifier.

Wherein, the asset location name query interface implements: and inputting an asset identifier, and calling an asset position name query interface corresponding to the fourth interface identifier to output information such as the position name of the asset corresponding to the asset identifier, wherein the asset is located in a building, a floor, a room and the like. For example, if the function corresponding to the asset track query interface is GetSpaceNameByAssetsID, the program/module corresponding to the GetSpaceNameByAssetsID function is called, so as to output information such as the location name of the asset corresponding to the asset identifier according to the input asset identifier.

Specifically, when the parameter type includes the location identifier and the fifth interface identifier, step 103 includes: and calling a position asset query interface according to the position identifier and the fifth interface identifier. And the data access interface corresponding to the fifth interface identifier is a position asset query interface. And calling a function of the position asset query interface corresponding to the fifth interface identifier according to the position identifier.

Wherein the location asset query interface implements: inputting the position identifier, and calling a position asset query interface corresponding to the fifth interface identifier to output asset information corresponding to the position identifier, such as the quantity of assets corresponding to the position identifier. For example, if the function corresponding to the asset trace query interface is getassetbyspace, the program/module corresponding to the getassetbyspace function is called to output asset information corresponding to the location identifier according to the input location identifier.

It should be noted that the above is only an example, the corresponding interface identifier also includes a plurality of types, and the data access interface corresponding to the identification information also includes a plurality of types.

And 104, inquiring asset data corresponding to the retrieval parameters from the asset database by using the corresponding data access interface.

The asset database stores three-dimensional spatial information of a building, asset information in the building, location information of an asset, and the like. It is understood that, before step 104, the method further includes: and storing the three-dimensional space information of the building, the asset information in the building and the position information of the asset information in an asset database, such as the asset database stored on the cloud. More specifically, as stored in a blockchain, etc. Since the original asset information such as the three-dimensional space information of the corresponding building, the asset information in the building, and the position information of the asset is stored in the asset database, the owner shares the original asset information, and thus the original asset information does not need to be stored in the software provider. The security and confidentiality of data are improved.

When the data access interface is an asset location query interface, step 104, comprises: inquiring assets corresponding to the asset identification from an asset database by using an asset position inquiry interface; acquiring position information of an asset; and using the acquired position information as asset data corresponding to the retrieval parameters. Specifically, location information for the asset is queried from an asset database.

The method can be applied to scenes needing to quickly find the asset position, and the asset position query interface can be used for quickly positioning the space position of the asset.

When the data access interface is an asset track query interface, step 104 includes: inquiring assets corresponding to the asset identification from an asset database by using an asset track inquiry interface; acquiring a plurality of position information of assets; generating a motion track of the asset according to the time of the plurality of position information; and taking the generated motion trail as asset data corresponding to the retrieval parameters. After acquiring a plurality of position information of the asset corresponding to the asset identifier, generating a motion track of the asset according to the time sequence of the plurality of position information. Specifically, a plurality of location information of the asset is queried from an asset database.

It is understood that the asset carries a sensor, and the position of the asset is sensed by the sensor, so as to obtain a plurality of position information of the asset.

In this case, the assets corresponding to the asset identifier include assets that can move after receiving the instruction, such as a sweeping robot, a guest greeting robot, and the like, and assets that are carried by the user and move along with the user, such as terminals for a call between buildings, and the like. The method can be applied to checking the sweeping track of the sweeping robot so as to quickly determine whether the sweeping robot finishes sweeping; the method can also be applied to checking the motion trail of the welcome robot so as to quickly determine whether the welcome robot moves in the specified area; the method can also be applied to quickly checking the position of a user carrying the terminal; but also in scenarios where it is quick to see if the asset is at some determined location, etc.

In this case, it is understood that the retrieval parameter in the asset retrieval request may further include a time parameter indicating a motion trajectory corresponding to the asset identifier within a time corresponding to the time parameter. Step 103, specifically including: and calling an asset track query interface according to the asset identifier, the second interface identifier and the time parameter. Step 104, specifically comprising: inquiring assets corresponding to the asset identification from an asset database by using an asset track inquiry interface; acquiring a plurality of position information of the asset within the time corresponding to the time parameter; generating a motion track of the asset in corresponding time according to the position information; and taking the generated motion trail as asset data corresponding to the retrieval parameters.

When the data access interface is an asset video query interface, step 104 includes: inquiring assets corresponding to the asset identification from an asset database by using an asset video inquiry interface; calling video information shot by assets; and taking the obtained video information as asset data corresponding to the retrieval parameters. Wherein, the video information of the assets shooting is called, including: calling video information shot by assets; and calling the video information currently shot by the asset, wherein the calling is understood as calling the camera to check the current monitoring information of the camera. Specifically, video information captured by the asset is queried and called from the asset database.

It will be appreciated that in this case, the retrieval parameters in the asset retrieval request may also include a time parameter. If the time parameter is included, step 103 specifically includes: and calling a video query interface according to the asset identifier, the third interface identifier and the time parameter. Step 104, specifically comprising: inquiring assets corresponding to the asset identification from an asset database by using a video inquiry interface; calling video information shot by the assets within the time corresponding to the time parameter; and taking the obtained video information as asset data corresponding to the retrieval parameters. It is understood that, if the search parameter includes a time parameter, the captured video information of the asset in the time corresponding to the time parameter is called. And if the retrieval parameters do not comprise the time parameters, calling the video information currently shot by the assets by default.

The method can be applied to the scene of water leakage or fire on a certain floor. And calling video information shot by the camera according to the camera on the floor so as to quickly check the reason of water leakage or fire. Or calling the video information currently shot by the camera to quickly check the current water leakage condition or fire condition so as to perform real-time monitoring.

When the data access interface is an asset location name query interface, step 104, comprises: inquiring assets corresponding to the asset identification from an asset database by using an asset position name inquiry interface; acquiring information such as a position name corresponding to the asset; and taking the acquired position name as asset data corresponding to the retrieval parameter. Wherein, the position name that the asset corresponds to includes: building name, floor, room, etc. Such as assets located in the 302 rooms of the third floor of the a building. Specifically, the location name corresponding to the asset is queried from the asset database.

The method can be applied to the scene that the position name corresponding to the asset needs to be quickly searched, and the position name of the asset can be quickly positioned by utilizing the asset position name query interface.

When the access interface is a location asset query interface, step 104, comprises: querying a position corresponding to the position identification from the asset database by using a position asset query interface; acquiring corresponding asset information in the position; and taking the obtained asset information as asset data corresponding to the retrieval parameters. Specifically, the corresponding asset information within the location is queried from the asset database.

The method can be applied to scenes of asset information which is quickly positioned at the position corresponding to a certain position mark, and the speed of acquiring the asset information in the position is increased. For example, in the above scenario of water leakage or fire on a certain floor, a certain coordinate range of the certain floor may leak water or fire, and the cameras in the corresponding range may be quickly queried according to the floor coordinates.

It should be noted that the above-mentioned scenarios are only some scenarios applied therein, and can also be applied in more scenarios.

105, transmitting the asset data to the terminal.

And sending the asset data to a terminal corresponding to the terminal user identification.

According to the method and the device for searching the asset data, after the asset searching request is received, the searching parameters in the asset searching request are analyzed, the data access interfaces corresponding to the parameter types are called, and the asset data corresponding to the searching parameters are inquired in the asset database. Therefore, the assets in the asset database can be managed differently through the provided data access interfaces, a software provider is not required to complete the function of managing the assets differently, and the dependence on the software provider is reduced.

In an actual scenario, the end users include an owner and a caller (including a software provider), which correspond to the first end user and the second end user, respectively. Because the owner shares the original asset information such as the three-dimensional space information of the building, the asset information in the building, the position information of the asset information and the like, the business side can set the authority of the caller, such as the access authority, and only the authorized caller can access the related data in the access authority. As shown in fig. 1d, a first end user sends a permission setting request to a server, and the server receives the permission setting request to set an asset access scope of a second end user through permission management. And the second terminal user sends an asset retrieval request to the server, and the server receives the asset retrieval request so as to determine whether the second terminal user has the right to access asset data corresponding to the retrieval parameters of the asset retrieval request through right management.

Before step 101, the step of receiving an asset retrieval request from a terminal, the method further comprises: and receiving an authority setting request sent by the first terminal user, and setting the authority of the second terminal user according to the authority setting request. Specifically, the method comprises the following steps: receiving an authority setting request sent by a first terminal user, wherein the acquired authority setting request comprises information of a second terminal user and an asset access range of the second terminal user, which is set by the first terminal user; setting the authority of the second terminal user according to the information of the second terminal user and the asset access range; acquiring current time, and generating a timestamp according to the current time; generating a dynamic key according to a preset encryption algorithm; sending the dynamic key to the second end user; first key data is generated based on the dynamic key and the timestamp.

Wherein the information of the second end user refers to user name information, account information, etc. of the second end user that can be used to access the data access interface. The set asset access range may be an asset in a specific building, an asset in a certain floor of a certain building, an asset in a certain room of a certain floor, or the like, and if the asset access range is set: assets in the first, second and third floors of the A floor. The preset encryption algorithm may be any encryption algorithm, such as an SHA256 encryption algorithm, and the SHA256 encryption algorithm is used to generate a dynamic key and send the dynamic key to the second end user. Generating first key data from the dynamic key and the timestamp, comprising: and performing encryption calculation, such as hash calculation, on the dynamic key and the timestamp to generate first key data. Wherein the cryptographic calculation to generate the first key data is an irreversible calculation to improve the security of the data.

And when the second terminal user logs in the server to access the data access interface, the second terminal user logs in by using the information of the second terminal user and the received dynamic key. The server receives the information of the second terminal user and the dynamic key input by the second terminal user; acquiring a corresponding timestamp when the dynamic key is generated; generating second key data according to the dynamic key input by the second terminal user and the acquired timestamp, wherein the manner of generating the second key data is the same as that of generating the first key data; judging whether the second key data is the same as the first key data; if the first terminal user is the same as the second terminal user, the second terminal user successfully logs in; and if not, the second terminal user fails to log in.

It will be appreciated that when the second end user logs in, the login is performed with the dynamic key to make the identity determination for the second end user. Only the second terminal user with the first terminal user having the set authority can log in to ensure the security of data access.

Further, when the retrieval parameter includes an asset identification and an end user identification, before step 105, the asset retrieval method further includes: detecting whether a terminal user corresponding to the terminal user identification has authority to acquire asset data; and if the terminal user corresponding to the user identification has the authority to acquire the asset data, executing the step of sending the asset data to the terminal. The step of detecting whether the terminal user corresponding to the terminal user identification has the authority to acquire the asset data comprises the following steps: acquiring an asset access range of a terminal user corresponding to a terminal user identifier; detecting whether the asset data exceeds the asset access range of the end user; if the asset data exceeds the asset access range of the terminal user, determining that the terminal user has no authority to acquire the asset data; and if the asset data does not exceed the asset access range of the terminal user, determining that the terminal user has the authority to acquire the asset data. And if the terminal user does not have the authority to acquire the asset data, performing alarm prompt. And further detecting whether the terminal user has the authority to acquire the corresponding asset data or not through the asset access range. If the asset access range is the assets in the first floor, the second floor and the third floor of the A floor, and the asset data obtained by query comprises the assets in the fifth floor of the A floor, the asset data exceeds the asset access range of the terminal user, and the terminal user does not have the authority to acquire the asset data.

Further, when the retrieval parameter includes the location identifier and the end user identifier, that is, the corresponding parameter type includes the location identifier and the fifth interface identifier. In this case, it is understood that, before the step of calling the location asset query interface according to the location identifier and the fifth interface identifier, the method further includes: detecting whether a terminal user corresponding to the terminal user identification has the authority to call a position inquiry interface or not; and if the terminal user has the authority to call the position inquiry interface, executing the step of calling the position asset inquiry interface according to the position identification and the fifth interface identification. The step of detecting whether the terminal user corresponding to the terminal user identification has the authority to call the position inquiry interface includes: acquiring an asset access range of a terminal user corresponding to a terminal user identifier; detecting whether the position corresponding to the position identification exceeds the asset access range of the terminal user; if so, determining that the terminal user corresponding to the terminal user identifier has the authority to call the position query interface; if not, determining that the terminal user corresponding to the terminal user identification has no authority to call the position query interface. And if the terminal user does not have the authority to call the position query interface, carrying out alarm prompt. If the asset access range is the assets in the first floor, the second floor and the third floor of the A floor, and the position corresponding to the position identifier is the fifth floor of the A floor, the position corresponding to the position identifier exceeds the asset access range of the terminal user, and the terminal user does not have the right to call the position query interface.

After the terminal user logs in, whether the terminal user has the authority to access the corresponding data access interface or not is further determined according to the asset access range of the terminal user, or whether the terminal user has the authority to acquire asset data obtained through inquiry of the corresponding data access interface or not is further determined, and the safety of data access is further improved. On the other hand, the owner (first end user) has the original asset information stored in the asset database and enjoys it, which further improves the security of the data as compared with the case where the original asset information is stored in the software provider. And the owner shares the original asset information, and the caller (including the software provider) with the corresponding authority can access the data of the original asset information by setting the corresponding authority, so that the data access safety is improved, and the data access efficiency is improved.

In this way, the three-dimensional spatial information of the entire building is obtained by analysis, and the structural information of points, lines, surfaces, and the like of all the three-dimensional spaces of the building is obtained.

It should be noted that if there is asset information in the building, the asset information needs to be analyzed, and then the asset information is used as leaf nodes.

It should be noted that after the BIM model or the CAD model is completed, information of all points, lines, faces, etc. in the BIM model or the CAD model has been identified, such as naming the information of the points, lines, faces, etc., adding attributes (such as coloring colors), etc.

Namely, the BIM model or the CAD model of the building is analyzed by using the third data import interface to obtain the three-dimensional space information of the building. In this case, the BIM model or CAD model of the corresponding building is imported through the corresponding third data import interface, and is parsed to obtain the three-dimensional spatial information of the building, which is different from the directly parsing building model described above.
