Referring to fig. 1 to 3, an embodiment of the present application provides an apparatus fault recording system, which includes: the device comprises a switch module 1, a switching value module 2, a communication module 3 and a storage module 4; the switch module 1 comprises a plurality of switches, the switching value module 2 comprises a plurality of input ports 21 and at least one communication port 22, each switch in the plurality of switches is connected with one input port 21, different switches are connected with different input ports 21, the communication port 22 of the switching value module 2 is connected with the communication module 3, and the communication module 3 is connected with the storage module 4; the switch module 1 is configured to generate a first indication signal after one of the switches is closed, and transmit the first indication signal to the switching value module 2 from the input port 21 connected to the switch, wherein the first indication signal is used for indicating a fault type; the switching value module 2 is configured to send fault detail information corresponding to the fault type to the communication module 3 in response to the first indication signal; the communication module 3 is configured to send the fault detail information to the storage module 4, so that the storage module 4 stores the fault detail information.

In the equipment fault recording system in the embodiment, because the switch module 1 can generate the first indication signal for indicating one fault type after one switch is closed, and the first indication signal is transmitted to the switching value module 2 from the input port 21 connected with the switch, the switching value module 2 can respond to the first indication signal and send the fault detailed information corresponding to the fault type to the communication module 3, the communication module 3 can send the fault detailed information to the storage module 4, and finally the storage module 4 can store the fault detailed information, when a worker finds the equipment fault, the worker only needs to close the switch corresponding to the fault type in the switch module 1, and can automatically store the fault detailed information into the storage module 4, thereby completing the recording of the fault detailed information without manually recording the equipment fault by the worker, the extra workload of workers is avoided being increased, recording errors can be avoided, and the recording of equipment faults can be completed quickly.

In this embodiment, the first indication signal is generated by a worker closing a switch in the switch module 1, specifically, a switch signal received by the switching value module 2 after the worker closes the switch, and obviously, the switch signal is a digital signal. When the switch is closed, the first indication signal input to the input terminal of the switching value module 2 may be a low level signal 0 or a high level signal 1. Specifically, for example, a switch is used, a first terminal of the switch is connected to the negative voltage output terminal of the power supply, and a second terminal of the switch is connected to an input port of the switching value module 2, so that after the switch is closed by a worker, a first indication signal with a low level 0 is generated and input to the switching value module 2 from the input port. In this embodiment, the switches of the switch module 1 may be dispersedly disposed on the workbench of a plurality of devices, or the switches may be collectively disposed on the workbench of one device, which is not limited in this embodiment.

Specifically, in this embodiment, different first indication signals are generated after different switches are closed, where the different first indication signals are used to indicate different fault types. That is, the fault type indicated by the first indication signal input by each switch to the input port of the switching value module 2 connected to the switch is different, and the switching value module 2 can identify different first indication signals to determine different fault types.

For example, taking the switch module 1 as an example that there are two switches (for ease of understanding, they are referred to as a first switch and a second switch), each switch corresponds to a different fault type, and the fault type corresponding to the first switch may be a fault of the frequency converter, and the fault type corresponding to the second switch may be a fault of the transformer (the frequency converter and the transformer are merely examples, and certainly, other devices may also be faulty, and no specific limitation is made in this embodiment). For example, when a worker finds that a frequency converter has a fault, the worker can directly close a first switch to generate a first indication signal, the first indication signal can indicate that a transformer has the fault, the switching value module 2 receives the first indication signal to judge, determines that the transformer has the fault, and sends fault detailed information related to the fault of the transformer to the communication module 3, the communication module 3 can send the fault detailed information to the storage module 4, and the storage module 4 stores the fault detailed information to complete recording of the equipment fault.

Preferably, the communication module 3 is a wireless communication module. Therefore, excessive wiring in the use of the equipment fault recording system in the embodiment can be avoided, the maintenance by workers is facilitated, and the transmission efficiency is higher and more stable.

In one embodiment, the switching value module 2 sends fault detailed information to the communication module 3 through an RS485 bus inside the switching value module, and sends information through the RS485 bus, so that safety and stability of information transmission can be effectively guaranteed. Specifically, the switching value module 2 includes an RS485 bus, the communication port 22 is a USB port, and the RS485 bus is connected to the communication module 3 through the USB port.

Of course, other wireless communication modules may also be used, for example, a wireless communication module based on a local area network, such as Wifi, ZigBee, etc., or a wireless communication module based on the internet of things, such as NBIOT, etc. No particular limitation is imposed in this embodiment.

Further optionally, the upper computer may combine other information related to the fault detail information with the fault detail information to generate a fault record and store the fault record in the storage module 4, for example, the other information may be stored in a data table configured in the upper computer, and the upper computer retrieves the related information related to the fault detail information from the data table to generate a fault record together with the fault detail information.

The received fault detail information corresponding to the plurality of fault types may be stored in a collective manner, so that the plurality of fault detail information may be recorded.

Optionally, the sending module 5 and the storage module 4 may be disposed on the same upper computer, or may be on other computers, PADs, mobile phones, or other mobile terminals.

For example, if the smart terminal is a mobile phone, the sending module 5 may be, for example, a module based on a cellular network, such as a GSM module, a GPRS module, etc., and sends the fault detail information to the smart device (i.e., the mobile phone) of the service personnel through a short message or a mobile data network. Or the sending module 5 may send the fault detail information to the intelligent device through mail so as to be known by maintenance personnel. This embodiment is not limited.

In order to enable the equipment fault recording system to correctly indicate the fault status of the equipment to other staff members after the staff members close the switches of the switch module 1, in one embodiment, the equipment fault recording system further comprises: a fault indication module 6, wherein the switching value module 2 further includes a plurality of output ports 23, the plurality of output ports correspond to the plurality of input ports 21 one to one, and the fault indication module 6 is coupled to each of the output ports 23; the switching value module 2 is further configured to respond to the first indication signal and to transmit a fault action signal from the output port 23 to the fault indication module 6, the fault action signal being for causing the fault indication module 6 to perform a predetermined action in response to the fault action signal.

In this embodiment, the fault action signal may enable the fault indication module 6 to execute a predetermined action, and obviously, after the worker sees the action of the fault indication module 6, the worker can directly correspond to a specific fault.

In this embodiment, the specific structure of the fault indication module 6 is not limited, and may be set according to actual requirements. In one embodiment, the fault indication module 6 includes a plurality of indicator lights 61, each indicator light 61 of the plurality of indicator lights 61 is connected to one of the output ports 23, and different indicator lights 61 are connected to different output ports 23; the indicator lamp 61 is lighted in response to the malfunction signal transmitted from the output port 23 connected thereto.

In this embodiment, the number of the input ports 21 and the number of the output ports 23 of the switching value module 2 may be the same, but the number of the switches and the number of the indicator lights 61 in the switching module 1 are not necessarily the same as the number of the input ports 21 and the number of the output ports 23, and the number of the switches and the number of the indicator lights 61 in the switching module 1 may be smaller than the number of the input ports 21 and the number of the output ports 23 of the switching value module 2.

For example, if the switching value module 2 is an eight-in eight-out switching value module 2, the eight-in eight-out switching value module 2 includes 8 input ports 21 and 8 output ports 23, and if there are 5 switches and 5 indicator lights in the switching module 1, the 5 switches may be respectively connected to any 5 input ports 21 in the 8 input ports 21, and the 5 indicator lights may be respectively connected to 5 output ports 23 corresponding to the 5 input ports 21 in the 8 output ports 23; if the number of the switches of the switch module 1 is 8 and the number of the indicator lamps is 8, the 8 switches can be respectively connected to all 8 input ports 21 of the 8 input ports 21, and the 8 indicator lamps can be respectively connected to 8 output ports 23 corresponding to the 8 input ports 21 of the 8 output ports 23; if the number of the switches of the switch module 1 is 8, and the number of the indicator lamps is 5, the 8 switches can be respectively connected to all 8 input ports 21 of the 8 input ports 21, and then the 5 indicator lamps can be respectively connected to any 5 output ports 23 of the 8 output ports 23, so that the indicator lamps can indicate the existence of the fault only by correctly closing the switches corresponding to the indicator lamps 61 by the staff. The rest cases can be analogized, and the limitation is not performed in the embodiment.

In one embodiment, the plurality of indicator lights 61 are co-anodic. In this embodiment, the indicator lamps 61 are light emitting diodes, the common anode means that anodes of the plurality of indicator lamps 61 are connected together and connected to the positive voltage output terminal of the power supply, a cathode of each indicator lamp 61 of the plurality of indicator lamps 61 is connected to the output port 23 of one switching value module 2, and cathodes of different indicator lamps 61 are connected to different output ports 23. At this time, since the plurality of indicator lamps 61 share the anode, the failure operation signal is a low level signal output from the corresponding output port 23 of the switching value module 2 connected to the indicator lamp 61.

In one embodiment, the indicator lights 61 may also be a common cathode, and the fault action signal is a high level signal output from the corresponding output port 23 of the switching value module 2 connected to the indicator light 61.

In one embodiment, the plurality of indicator lights 61 are colored differently to indicate the presence of different types of equipment malfunctions.

Optionally, in combination with the upper computer in the foregoing embodiment, the control of the on/off of the indicator light 61 may also be completed through the upper computer. For example, when the storage module 4 is a memory of an upper computer, a worker may also use the upper computer to actively send a fault action signal to the switching value module 2 from the communication module 3 connected to the storage module 4, and transmit the fault action signal to the fault indication module 6 from the output port 23, so that the fault indication module 6 performs a predetermined action, for example, a certain indicator lamp 61 is turned on, or a certain turned-on indicator lamp 61 is turned off, thereby completing effective control of the fault indication module 6 by the upper computer.

For example, the indicator lamp 61 may also have a control switch, so that the worker manually turns off the illuminated indicator lamp 61 or turns on the non-illuminated indicator lamp 61, for example, when the maintenance worker receives the fault detail information sent by the sending module 5 and arrives at the site to process the equipment fault and eliminate the fault, the maintenance worker may manually turn off the indicator lamp 61.

In one embodiment, the device fault recording system further includes: and the alarm module 7 is connected with the switching value module 2, and when at least one indicator lamp 61 in the plurality of indicator lamps 61 is turned on, the alarm module 7 gives an alarm. The alarm module 7 can effectively remind other workers of equipment faults.

For example, the alarm module 7 may be connected to an output port 23 that is not connected to the indicator lamp 61.

The specific structure of the alarm module 7 is not limited in this embodiment, and it may be set according to actual requirements. For example, the alarm device can be a buzzer or a loudspeaker, and sounds when alarming, and cooperates with the indicator lamp 61 in the fault indication module 6 to give an audible and visual alarm, so that the alarm can be more intuitive.

Alternatively, when the maintenance personnel receives the detailed fault information sent by the sending module 5 to arrive at the site to process the equipment fault and eliminate the fault, the switch closed in the switch module 1 may be switched off, so that the switching value module 2 sends the relevant information that the fault is eliminated to the storage module 4 through the communication module 3 in response to the signal that the switch is switched off, and the storage module 4 stores and records the relevant information that the fault is eliminated.

The device fault recording system in this embodiment may also be expanded more, and this embodiment is not limited.

In the following, a general description is given of one of the application scenarios, the working processes, and the like of the device fault recording system used by the staff for device fault recording in this embodiment, and it should be understood that the application scenarios and the working processes are only used for convenience of describing this embodiment, and are not meant to be limiting in this embodiment of the present application.

Illustratively, referring to fig. 3, a simple schematic diagram of the circuit connections of the respective modules in one device fault recording system in the present embodiment is shown. Wherein, the switching value module 2 comprises eight input ports 21, eight output ports 23 and a communication port 22, the switch module 1 comprises eight switches, each switch of the eight switches is connected with one input port 21, different switches are connected with different input ports 21, the second ends of the eight switches are connected with the negative output end of the power supply, the communication port 22 is connected with the communication module 3, the communication module 3 is connected with the storage module 4, the fault indication module 6 comprises five indicator lamps 61 with different colors, the five indicator lamps 61 are common anode, connected to the positive output of the power supply, and the cathode of each indicator light 61 of the five indicator lights 61 is connected to one output port 23, and the cathodes of the different indicator lights 61 are connected to the different output ports 23, the alarm module 7 includes a buzzer, one end of which is connected to the positive voltage output terminal of the power supply and the other end of which is connected to an output port 23 different from the five indicator lamps 61.

Further, in an application scenario, for example, during routine equipment inspection before the plant works, the staff can find whether each equipment has a fault by judging, when it is determined that there is an equipment fault, the equipment fault recording system in this embodiment can be used, as shown in fig. 2 and fig. 3, the switch corresponding to the fault type of the fault in the switch module 1 is closed, a first indication signal corresponding to the fault type is generated and transmitted from the input port 21 to the switching value module 2, the switching value module 2 judges the first indication signal, determines which switch is closed, specifically what fault type, and what fault details correspond to the fault (for example, the determination may be made by matching a data table stored in the switching value module and storing the data), and according to the determined result, the fault detailed information of the fault type is generated, the fault detailed information is sent to a communication module 3 connected with a communication port 22 through an RS485 bus of a switching value module 2, the communication module 3 comprises a raspberry dispatching circuit, the communication module 3 wirelessly transmits the fault detailed information to a storage module 4 (namely a storage of an upper computer) on the upper computer, and the storage module 4 stores and records the fault detailed information and can also display the fault detailed information on a screen of a terminal after storage. The storage module 4 may store and record a plurality of fault details generated after the plurality of switches are closed, respectively. Further, after the storage module 4 stores and records the fault information, the sending module 5 may send the fault detail information to the intelligent device (e.g., a mobile phone) of the maintenance personnel through a short message or an email. In addition, after the switching value module 2 determines which switch is closed, specifically what type of fault and what fault are determined according to the first indication signal, and obtains a result, the switching value module 2 can also send a fault action signal to the indicator lamp 61 in the fault indication module 6 from the output port 23 corresponding to the input port 21 to which the closed switch is connected, so that the corresponding indicator lamp 61 is turned on, and the indicator lamps 61 in the fault indication module 6 are different in color, which can be more convenient for indicating different equipment faults to other workers. Further, after the indicator lamp 61 is turned on, the buzzer in the alarm module 7 gives out a sound to give an alarm, so that the existence of equipment faults is better prompted. In addition, a failure operation signal may be transmitted to the switching value module 2 by the host computer in which the memory module 4 is located, and the switching value module 2 may transmit the failure operation signal to the failure indication module 6 to perform a predetermined operation, for example, turn on one of the indicator lamps 61 or turn off one of the turned-on indicator lamps 61.

Therefore, in the equipment fault recording system in the embodiment, because the switch module 1 can generate the first indication signal for indicating one fault type after one switch is closed, and the first indication signal is transmitted to the switching value module 2 from the input port 21 connected with the switch, the switching value module 2 can respond to the first indication signal and send the fault detailed information corresponding to the fault type to the communication module 3, the communication module 3 can send the fault detailed information to the storage module 4, and finally the storage module 4 can store the fault detailed information, when an operator finds an equipment fault, the fault detailed information can be automatically stored in the storage module 4 only by closing the switch corresponding to the fault type in the switch module 1, so that the recording of the fault detailed information is completed without manually recording the equipment fault by the operator, the extra workload of workers is avoided being increased, recording errors can be avoided, and the recording of equipment faults can be completed quickly.
