Background
The production of equipment production type enterprises mainly depends on various equipment, at present, in the field, the proportion of production line halt caused by equipment faults is high, once the production line is stopped, the loss of a factory is large, and the cost is indirectly increased, including defective products, efficiency loss and the like. Thus, the safety of industrial equipment has a great impact on the cost and efficiency of the plant. For the equipment security department, a plant will typically set 2 Key Performance Indicators (KPIs), equipment failure rates, and security maintenance sums. The electromechanical sector is required to be below a certain limit.
At present, a power system of a factory, which is generally not produced with high precision, generally comprises a PLC, a frequency converter, a motor, a synchronizer and the like. The system displays the fault reason through a frequency converter only after the fault occurs, or searches the problem reason through other methods. Since losses have already been created, it is only desirable to reduce the losses. If the problems can be found in advance, the problems can be treated in advance when the problems are very small, the normal operation of equipment is not influenced, and the method is very important for most electromechanical departments. Because the frequency converter is the key that the power system problem shows, many mechanical problems, for example motor overload, bearing lack of oil, bearing card, the high temperature scheduling problem all can reflect through electric current, voltage, temperature, the electric phase that the frequency converter detected to reach the effect of early warning in advance, let the problem expose in advance, handle in advance, thereby reduce the fault rate, need not wait to reach motor or other equipment thoroughly burn out, thereby reduce the guarantee maintenance amount of money.
The traditional method for detecting the state information of the frequency converter is to collect a multifunctional output point on the frequency converter through a PLC (programmable logic controller), namely, the multifunctional output point of the frequency converter is butted through an I/O (input/output) interface of the PLC, and a corresponding address is read through configuration software to obtain and display fault information. Because PLC can only collect a signal, and early warning of what reason cannot be collected, in addition, the output point of the frequency converter is limited, and only one of more modes can be adopted, such as warning or early warning; the collected information is stored in each production line locally, valuable analysis such as quality evaluation and the like cannot be carried out on the frequency converter, after the frequency converter breaks down, electromechanical workers need to go to an industrial field to maintain the equipment, and configuration software cannot inform the electromechanical workers in time.
With the popularization of information networks in the field of industrial technologies, in the prior art, a 2G/3G network transparent transmission module is connected with a frequency converter through an RS485 interface, and the operation data of the frequency converter is uploaded to cloud software (a cloud server) so as to perform comprehensive analysis on the operation data of the frequency converter. However, in the scheme, each frequency converter acquisition device adopts the 2G/3G network transparent transmission module to communicate with the cloud software, so that the hardware cost and the network flow rate charge are increased, and in addition, in the fault detection process, the cloud server actively initiates inquiry type acquisition and data processing, so that the server load is large, and the data acquisition and processing efficiency of the server is reduced.
Aiming at the problems of low efficiency and high cost caused by inquiry type acquisition and data processing initiated by a server when a plurality of devices to be detected are subjected to fault detection in the prior art, an effective solution is not provided at present.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In accordance with an embodiment of the present invention, there is provided an apparatus failure detection method embodiment, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than that described herein.
Fig. 1 is a flowchart of an apparatus fault detection method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, the acquisition equipment detects whether network access information from the network access equipment is received or not, wherein the network access information is used for prompting the acquisition equipment to access a target network.
As an optional embodiment, the collecting device may be a collector for collecting operation data of a frequency converter in various production devices; the network access device may be a gateway device for accessing at least one acquisition device to a target network (which may be any local area network); the network access information may be information for notifying or prompting the acquisition device to access to a target network in communication with the network access device.
In an optional embodiment, the communication mode between the acquisition device and the network access device includes, but is not limited to, any of the following: LoRa radio frequency (ultra-long distance wireless transmission technology based on spread spectrum technology), RS485 serial bus, CAN bus and the like; for example, the system can also be a Bluetooth, WiFI, Zigbee, 2G/3G/4G network module and the like.
It should be noted that, in the prior art, a 2G/3G network transparent transmission module needs to be arranged for each frequency converter acquisition device, and as the number of production devices increases, a large amount of hardware devices need to be invested. In addition, each frequency converter acquisition device is communicated with the server through the 2G/3G network transparent transmission module, so that a large amount of flow fee is continuously generated. According to the method and the system, the plurality of acquisition devices are accessed to the target network through the self-established wireless networking and the network access device, the flow fee is not needed, and the cost is saved. Because the LoRa technology has the characteristics of long distance, low power consumption, multiple nodes, low cost and the like, as a preferred embodiment, the communication mode between the acquisition device and the network access device is the LoRa radio frequency.

According to the method and the device, the network access information is sent through the network access device, and each acquisition device is automatically accessed to the target network without user configuration, so that user operation is reduced, and user experience is improved.
And step S104, under the condition that the network access information is received, the acquisition equipment uploads the acquired state information of at least one device to be detected to the server through the network access equipment, wherein the server determines whether to output early warning information or not according to the state information.

The acquisition equipment is connected with one or more to-be-detected equipment and is used for acquiring the running state information of the to-be-detected equipment, and after a communication link is established between the acquisition equipment and the network access equipment, the acquired running state information of the to-be-detected equipment is uploaded to the server through the network access equipment, so that the server can determine whether to output early warning information according to the received state information of the to-be-detected equipment, and the early warning information can be information for prompting that the to-be-detected equipment breaks down or certain running parameter exceeds a preset index, so that a worker can be informed in time.
In an alternative embodiment, fig. 2 is a schematic diagram of an alternative device failure detection system according to an embodiment of the present invention, as shown in fig. 2, the system includes: the system comprises a server, network access equipment, acquisition equipment, equipment to be detected and a user terminal, wherein each acquisition equipment is communicated with at least one equipment to be detected (the communication mode comprises protocols such as RS485, CAN, Modbus and the like, but not limited thereto) and is used for acquiring operation data such as temperature, voltage, current and the like of the equipment to be detected (for example, a frequency converter); and uploading data to a network access device (also called a gateway) through a lora radio frequency module, an RS485 module, a CAN module and the like, uploading the received data acquired by at least one acquisition device to a server through a wired or wireless network (including but not limited to 4G, GPRS, WiFi and the like), judging whether the operation data exceed a preset early warning value or not after the server receives the operation data of one or more devices to be detected, and outputting early warning information under the condition that the operation data exceed the early warning value. As an optional implementation manner, the server may push the warning information to the user terminal of the staff by a short message, various communication software APPs (including but not credited to WeChat, QQ, etc.), and a public number; as another alternative, the early warning information can be directly displayed in a form of a Web end, and a worker can view the early warning information in a form of accessing a Web page.
As a preferred embodiment, in the embodiments of the present application, a device to be detected is used as a frequency converter for explanation, and an acquisition device communicates with the frequency converter through an RS485 bus to read current state information of the frequency converter, where the state information includes current dc bus voltage, output current, frequency converter temperature, fault code, and other information.
It should be noted that, as an optional implementation manner, multiple sets of different brands of frequency converter communication protocols are built in the acquisition device, and when the acquisition device is used, the acquisition device can be used only by selecting a brand model code and a bus address of the frequency converter, and the setting can be selected through a terminal with a button, and can also be issued through a server. Optionally, in the case that the device to be detected is a frequency converter, the collecting device may additionally provide a signal input for detecting a bearing temperature of the motor, or an ambient temperature, or a parameter controlled by a system formed by the frequency converter and the motor (e.g., a water pressure controlled by the frequency converter controlling the water pump, and an air pressure controlled by the frequency converter controlling the compressor) so as to expand the whole monitoring system.
It can be seen from the above that, in the above embodiments of the present application, the collecting device connected to at least one device to be detected detects whether network access information from the network access device is received, and when the network access information sent by the network access device is received, the collecting device uploads the collected state information of the at least one device to be detected to the server through the network access device, so that the server can determine whether to output the early warning information according to the received state information of the device to be detected, and the purpose of uploading the state information of the at least one device to be detected collected by each collecting device to the server in sequence through the network access device is achieved, thereby achieving the technical effects of reducing the load of the server and improving the data processing efficiency of the server, and further solving the problems of low efficiency, low data processing efficiency, low cost, and the like caused by the server initiating query type collection and data processing when the fault detection is performed on a plurality of devices to be, The technical problem of high cost.
In an optional embodiment, as shown in fig. 3, before the acquiring device detects whether the network access information from the network access device is received, the method may further include the following steps:
step S302, monitoring a beacon data packet from a network access device by a collection device, wherein the beacon data packet is used for informing at least one collection device to send a network access request data packet to the network access device;
step S304, the acquisition equipment judges whether the channel of the network access equipment is idle or not under the condition of monitoring the beacon data packet of the network access equipment;
step S306, under the condition that the channel of the network access device is idle, the acquisition device sends a network access request data packet to the network access device, wherein the network access request data packet at least comprises: and collecting identification information of the equipment.
Specifically, in the above embodiment, the beacon packet is a regular wireless packet sent by the network access device at a specified time interval, and is used to notify at least one acquisition device connected to the network access device to send a network access request packet to the network access device; the network access equipment sends the beacon data packet according to a certain period, and each acquisition equipment judges whether the channel of the network access equipment is idle after monitoring the beacon data packet, so that the network access request data packet is sent to the network access equipment under the condition that the channel of the network access equipment is idle.
It is easy to notice that, because a plurality of collection devices upload the collected state information of at least one device to be detected to the server through a network access device, in order to avoid the conflict of data uploaded by a plurality of collection devices to the occupation of the network access device, the network access device needs to upload the state information of at least one device to be detected collected by each collection device to the server in sequence.
Based on the solutions disclosed in the above steps S302 to S306, the multiple acquisition devices connected to the network access device send the network access request data packet when monitoring that the channel of the network access device is idle, so that channel collision caused by the multiple acquisition devices sending the network access request packet at the same time is avoided.
As an optional embodiment, the network access device has a full duplex capability for performing uplink and downlink simultaneously, and includes at least two channels: the device comprises an uplink channel and a downlink channel, wherein the uplink channel is used for the acquisition equipment to send data to the network access equipment; the downlink channel is used for the network access equipment to send data to the acquisition equipment. After the network access equipment sends a beacon data packet to at least one acquisition equipment connected with the network access equipment through a downlink channel, each acquisition equipment monitors whether an uplink channel of the network access equipment is idle (namely whether the uplink channel of the network access equipment is occupied by other acquisition equipment), if the uplink channel of the network access equipment is idle, a network access request data packet is sent, if the uplink channel of the network access equipment is occupied, it indicates that other acquisition equipment has sent the network access request data packet to the network access equipment, and when the network access equipment waits for sending the beacon data packet next time, whether the channel of the network access equipment is idle is monitored again.
In an optional embodiment, as shown in fig. 3, in a case that an uplink channel of the network access device is idle, after the acquisition device sends the network access request packet to the network access device, the method may further include the following steps:
step S308, the acquisition equipment detects whether network access information from the network access equipment is received within a preset time period;
step S310, if the network access information from the network access device is not received within the preset time period, the network access request packet is retransmitted after the beacon packet from the network access device is received next time.
Specifically, in the above embodiment, after any one of the collection devices connected to the network access device monitors that the uplink channel of the network access device is idle and sends a network access request packet to the network access device, the collection device detects whether network access information from the network access device (i.e., response information of the network access device to the network access request packet sent by the collection device) is received within a preset time period, and if the network access information from the network access device is not received within the preset time period, the collection device resends the network access request packet after receiving a beacon packet from the network access device next time.
Optionally, the method may further include: step S312, when the acquisition device detects that the network access information sent by the network access device is information refusing the network access of the acquisition device, the network access request packet is stopped from being retransmitted. Specifically, when the acquisition device is an acquisition device to which the server prohibits data from being uploaded or an acquisition device prohibited from being added to the network access device, when a beacon data packet from the network access device is received, even if the channel of the network access device is monitored to be idle, the acquisition device does not send a network access request packet to the network access device any more, and the purpose that the acquisition device prohibited from being accessed to the network or prohibited from uploading data occupies a network access time window for a long time can be avoided.
In an optional embodiment, as shown in fig. 4, before the acquiring device uploads the acquired state information of the at least one device to be detected to the server through the network access device under the condition that the network access information is received, the method may further include the following steps:
step S402, under the condition of receiving the network access information, the acquisition device initiates a query request to the server through the network access device, wherein the query request is used for querying the configuration information of the acquisition device, and the configuration information at least comprises: acquiring identification information of at least one device to be detected connected with the acquisition equipment, early warning conditions of each device to be detected connected with the acquisition equipment, and an acquisition cycle of the acquisition equipment;
and step S404, receiving the query result returned by the server through the network access device.
Specifically, in the above embodiment, after the acquisition device receives the network access information and joins the target network of the network access device, the acquisition device initiates an inquiry request to the server through the network access device, so as to inquire configuration information of the acquisition device, including but not limited to identification information of at least one device to be detected connected to the acquisition device, an early warning condition of each device to be detected connected to the acquisition device, and an acquisition cycle of the acquisition device.
Optionally, the network access device may be connected to the server through wifi, 2G, 3G, 4G, or a wired network. As an optional implementation manner, according to the security level configured by the system, the network access device (gateway) needs to authenticate the accessed acquisition device, mainly aiming at the serial number of the acquisition device. If the system is configured without authentication, the network access device (gateway) allows devices with arbitrary serial numbers to join the network. The server is responsible for collecting data uploaded from the network access equipment (gateway), and whether early warning or alarming is needed or not is judged according to the running data and the state of the frequency converter reported by the acquisition equipment. According to the security level of the system configuration, the server compares the serial numbers of the network access device (gateway) and the acquisition device, and if the serial numbers of the network access device (gateway) or the acquisition device are not in the list of the devices allowed to be connected, the server discards the data packet.
Optionally, based on the foregoing embodiment, as an optional implementation manner, after receiving a query result returned by the server through the network access device, the method may further include the following steps:
step S406, the acquisition device acquires the operation data of at least one device to be detected connected with the acquisition device according to an acquisition cycle, wherein the operation data comprises at least one of the following data: the method comprises the following steps of (1) carrying out direct current bus voltage, output current, temperature of equipment to be detected and fault codes;

and S410, uploading the state information of at least one device to be detected, which is acquired by the acquisition equipment, to a server through the network access equipment according to the judgment result.
Specifically, in the above embodiment, after the acquisition device receives the configuration information returned by the server through the network access device, because the configuration information includes the early warning condition of each device to be detected connected to the acquisition device, after the acquisition device acquires the operation data of at least one device to be detected connected to the acquisition device, the acquisition device may determine whether the operation data of each device to be detected connected to the acquisition device reaches the corresponding early warning condition based on the identification information of each device to be detected, and determine the data uploaded to the server according to the determination result.
Through the embodiment, the purpose of primarily screening data can be achieved, and the operation data of the equipment to be detected, which is detected to be abnormal by the acquisition equipment, is uploaded to the server.
In an optional embodiment, the channel of the network access device may include: the method includes an uplink channel, a downlink channel and an emergency channel, wherein in step S410, according to a judgment result, the state information of at least one device to be detected, which is acquired by the acquisition device, is uploaded to a server through the network access device, and the method may include the following steps:
