[0072] The application will now be further described with reference to the drawings. These drawings show only the essential features of the application and are not limiting in any way. These drawings show in:

[0073] In various water conservancy and hydropower projects, detection of different equipment and different systems is involved, specifically, safety evaluation and fault diagnosis of various hydraulic steel gates, ship locks, etc. require providing state information of project parameters such as nondestructive testing, material performance testing, corrosion testing, structural stress testing, residual stress testing, vibration testing, modal analysis, finite element calculation, etc. Safety evaluation of various hoists, trash removal machines, ship lifts, etc. requires providing state information of project parameters such as nondestructive testing, material performance testing, corrosion testing, hoisting force testing, vibration testing, steel wire rope defect testing, deformation amount testing, etc. Water diversion pressure steel pipes, bifurcated pipes and volutes require providing state information of project parameters such as nondestructive testing, material performance testing, corrosion testing, structural stress testing, residual stress testing, vibration testing, water pressure testing, etc. For dredging machinery such as various dredging ships and dredging machines, technical appraisal and inspection and testing require providing state information of project parameters such as production capacity, production rate, slurry concentration, etc. For concrete mixing machinery such as various concrete mixing buildings (stations), technical appraisal and inspection and testing require providing state information of project parameters such as dust concentration, production rate, structural stress testing, etc. For hoisting machinery such as various hoisting machinery such as portal cranes, bridge cranes, cranes, trolleys, etc., safety evaluation and technical appraisal require providing state information of project parameters such as nondestructive testing, material performance testing, corrosion testing, hoisting force testing, vibration testing, steel wire rope defect testing, deformation amount testing, etc. For auxiliary equipment of power plants such as various material taking machines and material unloading machines, performance testing and technical appraisal require providing state information of project parameters such as production rate, structural stress testing, vibration testing, nondestructive testing, etc. For steel structure engineering, state information of project parameters such as deformation amount testing, nondestructive testing, material performance testing, load testing, etc. of various steel structures is required.

[0074] It can be seen that in the water conservancy and hydropower engineering, the state information (i.e. detection data) is numerous, and the pure reliance on manpower is not only time-consuming and labor-consuming, but also poor in timeliness; with the continuous development of sensor technology, various types of sensors for various types of data emerge as the times require, and the detection of the above-mentioned related data can be realized through the sensors, therefore, the present application provides a novel, robust, high-accuracy detection system which can be remotely monitored based on wireless sensor technology.

[0075] The detection system provided by the present application is as shown in Figure 1 The present application provides a water conservancy and hydropower engineering detection system, the detection system comprises various types of sensors, at least one access point and a central processor; wherein different sensors are arranged at different detection targets, each sensor is connected with a corresponding access point, and all the access points are connected with the central processor to realize the collection of required data.

[0076] The sensor is used for collecting the state information of the ith detection target and transmitting the state information to the corresponding access point;

[0077] The access point is used for receiving the state information of the ith detection target, calculating the abnormal data according to the received state information, obtaining the weight and abnormal value of the ith detection target and sending them to the central processor; the access point is also used for sending the state information of the ith detection target to the central processor;

[0078] The central processor is used for receiving the weight and abnormal value of the detection target sent by each access point, calculating the transmission time slot of each detection target and sending it to the corresponding access point; and is also used for receiving the state information of the sensor and determining the state of each detection target.

[0079] In the scenario involved in the present application, each detection target has at least one access point; the access point is connected with different types of sensors to obtain the state of the detection target; the central processor allocates a data transmission time slot to each access point according to the target weight and abnormal value sent by the access point to send the state information. According to the scheme of the present application, the interaction between the local detection system and the remote central processor can be realized, and the transmission of various types of abnormalities and related monitoring data to the remote central processor in a timely manner can be ensured to facilitate the decision-making of the upper system. Through the above-mentioned manner, the superior department of the water conservancy and hydropower detection system can timely know the situation of the water conservancy and hydropower system in each place, and determine the global detection system maintenance strategy through comprehensive evaluation; through the above-mentioned manner, the timeliness of data transmission is effectively improved, and the overall overall arrangement is also improved, which is convenient for remote maintenance and can significantly reduce the inconvenience caused by business trips of engineering personnel. At the same time, according to the transmission time slot allocation according to the situation of each regional detection target, the flexibility of data transmission can be improved, the timeliness of emergency data transmission can be improved, and the adverse effects caused by the fixed transmission mode can be reduced.

[0080] In the preferred embodiment, as shown in Figure 2 the at least one access point comprises a first access point and a second access point;

[0081] The access point comprises a first access point and a second access point; the first access point and the second access point support multiple types of communication protocols; the multiple types of communication protocols at least comprise a first communication protocol and a second communication protocol, wherein the first communication protocol is different from the second communication protocol;

[0082] When the first access point communicates with the central processor based on the first communication protocol, the second access point communicates with the central processor based on the second communication protocol; the data transmitted by the first access point and the second access point are different.

[0083] In the scheme provided by the present application, the access point supports multiple communication protocols, and the transmission of the weight and abnormal data and the state information is realized through different communication protocols. In the preferred embodiment of the present application, the first access point and the second access point are used to realize the data transmission of the detected target, and each corresponds to one detected target. Generally, the data of the first access point and the second access point are redundant and backup each other, but in the actual communication process, when the first access point transmits the weight and the abnormal value, the second access point is used to transmit the state information and / or the size of the state information; through the data transmission of the two access points, the central processor can conveniently associate and verify the received various data, thereby ensuring the reliability of the data transmission. Further, the access point supports multiple communication protocols, and the transmission of the weight and abnormal data and the state information is realized through different communication protocols; because the access points are in different environments, the wireless transmission of the data may be interfered to different degrees due to the difference of the external environment. Therefore, in the data transmission, different transmission protocols are used by different access points, thereby further improving the accuracy of the data transmission. In the preferred embodiment, the two access points determine the state of each other through the handshake message, when it is determined through the handshake message that the other access point is normal, the data transmission is performed according to the above method; when one of the access points is abnormal, the other access point will feed back the identification ID of the abnormal access point to the remote central processor; at this time, the central processor will obtain the weight, the abnormal value and the related state information through the normal access point; wherein, the protocols used by the normal access point to transmit the weight, the abnormal value and the state information can be the same or different, in the preferred embodiment, in order to ensure the safety of the data, different communication protocols can be selected for transmission.

[0084] In the data transmission scenario targeted by the present application, since multiple access points are involved and the types of data transmission can be the same or different, in order to facilitate the remote central processor to process data, the present application further associates through the data packet header, sets the packet header for each type of data and sets it at the header of each type of data, thereby facilitating the data identification and association of the access point and the central processor. Further, the packet header can be set in the following way: two are selected from the IDs of the two access points and the ID of the detection target to perform XOR operation to obtain; that is two are selected from the three to perform XOR operation; or, the packet header includes values.

[0085] The packet header obtained by the above-mentioned way not only has a simple calculation method, but also is easy to calculate and difficult to be imitated and tampered, further improving the security of data transmission.

[0086] After the access point calculates the abnormal data according to the received state information, the weight and abnormal value of the ith detection target are obtained, including:

[0087] The access point determines the weight and abnormal value of the ith detection target according to the number of abnormal detection parameters in the received state information of the ith detection target. Wherein, the weight W i of the ith detection target is calculated according to the following formula:

[0088]

[0089] Wherein, K i is the number of detection parameters of the ith detection target received by the access point, N i is the total number of abnormal detection parameters, and M i is the number of serious abnormal detection parameters; the abnormal detection parameter is relative to the normal detection parameter, which can be understood as a value exceeding a certain range of the normal detection parameter. The serious abnormal detection parameter is a detection parameter exceeding a larger preset range of the normal value among the abnormal detection parameters.

[0090] The abnormal value R i of the ith detection target is determined according to the data size Q i (i.e. the size of the data packet) of the N i abnormal detection parameters and the data size P i of the M i serious abnormal detection parameters.

[0091] The present application provides a novel abnormality and weight calculation method, the above-mentioned calculation method not only has a simple algorithm, does not need to collect redundant data, only needs to obtain the number of abnormalities and the data size, and has small pressure on the system. In the method provided by the present application, the unit of data is bite.

[0092] The central processor is configured to receive the weight and the abnormal value of each detection target sent by the access point, and calculate the transmission time slot of each detection target, including:

[0093] The central processor determines the data transmission coefficient X of each detection target according to the weight and the abnormal value of each detection target. i ; wherein X i = W i *R i .

[0094] According to the data transmission coefficient X i , each detection target is sorted in descending order, and the transmission order of the state information corresponding to each detection target is determined.

[0095] The central processor obtains the size Y i of the state information of each detection target.

[0096] The central processor determines the transmission time length t of the state information corresponding to each detection target according to the size Y i of the state information corresponding to each detection target.

[0097] The central processor determines the transmission time slot of each detection target according to the data transmission coefficient X i and the transmission time length t of each detection target.

[0098] The access point sends the state information of the i-th detection target to the central processor according to the transmission time slot sent by the central processor.

[0099] In the preferred embodiment, the central processor is configured to receive the weight and the abnormal value of each detection target sent by the access point, and calculate the transmission time slot of each detection target, and further includes:

[0100] The central processor further feeds back the data transmission coefficient X i of the i-th detection target to the access point.

[0101] The access point calculates its own data transmission coefficient, and when the data transmission coefficient calculated by the access point is consistent with the data transmission coefficient X i of the i-th detection target received, the access point feeds back the size Y i of the state information of the i-th detection target to the central processor.

[0102] In order to improve the reliability of data transmission, the present application defines the format of the data transmission coefficient during the data transmission process, verifies the data transmission coefficient, and determines that the central processor has received the weight and the abnormal value, and then feeds back the data size.

[0103] In the preferred embodiment, the central processor is used to receive the weight of each access point sent detection target and the abnormal value to calculate the transmission time slot of each detection target, comprising:

[0104] The central processor determines the first transmission time slot of the state information of the detection target according to the weight and the abnormal value of the detection target;

[0105] The second transmission time slot is determined according to the first transmission time slot;

[0106] The transmission time slot of the state information of the detection target is determined according to the first transmission time slot and the second transmission time slot.

[0107] Since new state information may occur during data transmission, which results in that the allocated data transmission time slot cannot meet the actual data needs, therefore, the application sets a redundant time slot, i.e. the second transmission time slot, when allocating the transmission time slot, so as to ensure the integrity of data transmission. Preferably, the redundant time slot is 1 / 3 of the transmission time slot. Through the above-mentioned mode, the integrity of data transmission can be ensured.

[0108] In the preferred embodiment, after the central processor receives the state information sent by the access point according to the transmission time slot, it further comprises: when the first transmission time slot ends, determining whether the received state information includes an end identifier;

[0109] When the central processor determines that the received state information does not include the end identifier, it continues to receive the state information until the second transmission time slot ends.

[0110] In the preferred embodiment, after the central processor receives the above-mentioned data, it identifies the tail identifier of the data. If the tail identifier is not identified, it will feed back the transmission exception to the corresponding access point, and the access point will feed back the data size calculated again to the central processor, so as to redefine the transmission time slot, so as to further ensure the integrity of data transmission.

[0111] The application also provides a water conservancy and hydropower engineering detection method, and the flow chart is as shown in Figure 3

[0112] The sensor collects the state information of the ith detection target and transmits it to the corresponding access point;

[0113] The access point receives the state information of the ith detection target, and after calculating the abnormal data according to the received state information, obtains the weight and the abnormal value of the ith detection target and sends them to the central processor. The access point also sends the state information of the ith detection target to the central processor;

[0114] ​The central processor receives the weight and abnormal value of each detection target sent by the access points, calculates the transmission time slot of each detection target, and sends it to the corresponding access point; the central processor also receives the state information of the sensor, and then determines the state of each detection target.

[0115] In the scenario related to the present application, each detection target has at least one access point; the access point is connected with different types of sensors to obtain the state of the detection target; the central processor allocates data transmission time slots for each access point according to the target weight and abnormal value sent by the access point, so as to send the state information. According to the scheme of the present application, the interaction between the local detection system and the remote central processor can be realized, and the transmission of various types of abnormalities and related monitoring data to the remote central processor in a timely manner can be ensured to facilitate the decision of the upper system. In the above manner, the superior department of the water conservancy and hydropower detection system can timely know the situation of the water conservancy and hydropower system in each place, and determine the global detection system maintenance strategy through comprehensive evaluation; through the above manner, not only the timeliness of data transmission is effectively improved, but also the overall layout is improved, which is convenient for remote maintenance and can significantly reduce the inconvenience caused by business trips. At the same time, according to the situation of each regional detection target, the transmission time slot is allocated, which can improve the flexibility of data transmission, improve the timeliness of emergency data transmission, and reduce the adverse effects caused by fixed transmission mode.

[0116] In the preferred embodiment, in the scheme provided by the present application, the access point supports multiple communication protocols, and the transmission of weight and abnormal data and state information is realized through different communication protocols. In the preferred embodiment of the present application, the first access point and the second access point are used to realize the data transmission of the detection target, and each corresponds to one detection target. Generally, the data of the first access point and the second access point is redundant and backup each other, but in the actual communication process, when the first access point sends the weight and abnormal value, the second access point is used to transmit the state information and / or the size of the state information; through the transmission of data by two access points, the central processor can conveniently associate and verify the received various types of data, thereby ensuring the reliability of data transmission. Further, the access point supports multiple communication protocols, and the transmission of weight and abnormal data and state information is realized through different communication protocols; since the access points are in different environments, the wireless transmission of data may be interfered to different degrees due to the difference of external environment. Therefore, in the data transmission, different transmission protocols are used by different access points for transmission, which can further improve the accuracy of data transmission.

[0117] In the data transmission scenario, since multiple access points are involved and the types of data transmission can be the same or different, in order to facilitate the remote central processor to process data, the application further associates the data through the message header, sets the message header for each type of data and sets it in the header of each type of data, thereby facilitating the data identification and association of the access point and the central processor. Further, the message header can be set in the following way: randomly selecting two from the IDs of the two access points and the ID of the detection target to perform XOR operation; that is, Random2(ID1 XOR ID2 XOR ID3): selecting two from the three to perform XOR operation; or, the message header includes the value of ID1 XOR ID2 XOR ID3.

[0118] The message header obtained by the above-mentioned manner is not only simple in calculation, but also easy to calculate and difficult to be imitated and tampered, thereby further improving the security of data transmission.

[0119] The application also provides a water conservancy and hydropower engineering detection system, comprising a memory and a processor, the memory stores a computer program executable on the processor, and the processor implements the above method when executing the computer program.

[0120] The application also provides a computer readable medium having non-volatile program code executable by a processor, and the program code causes the processor to execute the method.
