As shown in Fig. 2, the noise detection device 50 in one embodiment of the utility model is included as each component of control The control base board 51 of operating circuit plate, and the signal cable 54 for being respectively connected each component with control base board 51, and detection signal Cable 54 is delivered to the whether abnormal detection circuit 52 of voltage signal of control base board 51, and be connected with control base board 51 and Detection circuit 52 detects the control panel 13 that prompt message is outwardly sent during abnormal voltage signal.

The characteristics of voltage of corresponding component can fluctuate when present embodiment is produced using noise, by judging what is received Whether voltage signal, which occurs voltage, changes to determine to cause the component and its reason of noise generation, then goes adjustment to scheme according to result Position or medium as forming apparatus, so as to eliminate or reduce the generation of noise.

At work, respective voltage signal is delivered to control base board 51 by each component by signal cable 54, is such as scanned Unit 16；Detection circuit 52 is detected each voltage signal according to predetermined examination criteria, when the voltage of some component conveying When signal meets examination criteria, then its information is sent to control panel 13, and the information is then passed through image by control panel 13 Or the mode of sound is outwardly transmitted, to prompt user or maintenance personnel to pay attention to solve the problems, such as.

In present embodiment, the examination criteria of detection circuit 52 is set generally be directed to the level change of voltage signal , because when the work of any one component causes noise to occur, then its corresponding voltage level will change, and The change is usually that the level frequent of the voltage signal of component conveying becomes higher, so, examination criteria can be arranged to more than one Determine the voltage signal of frequency, that is, represent noise phenomenon occur, control panel 13 can be sent this information to, by control panel 13 prompting users simultaneously provide the component names and solution for noise occur, by user or maintenance personnel according to prompting to image shape Operated into device, including replace the disposal options such as the position of medium, Mobile image forming apparatus 100, so as to solve noise Problem.

Specific voltage signal can be produced by ground wire, and ground wire is the line that each component is grounded respectively, wherein, signal cable 54 can include the sub- ground wire that is grounded respectively of each component, and the main ground wire that control base board 51 is grounded, sub- ground wire can mark for FG1-FGn, and main ground wire is then labeled as SG, sub- ground wire FG and main ground wire SG and conveys voltage signal to control base board 51 respectively, and Voltage level between FG and SG is identical.If any noise is produced in image processing system 100, then, the voltage of FG and SG Level instantaneously changes.Detection circuit 52 can be using the SG of control base board 51 as benchmark, if the level generation of FG is specific The change of above voltage level, then, carrying out the level of signal of self-detection circuit 52 also can equally change, so as to can determine that production Noise is given birth to.

In an embodiment of the utility model, filtering can be set between signal cable 54 and detection circuit 52 Circuit 53, the filtering circuit 53 are used for the mistake that various signals are delivered to detection circuit 52 and control base board 51 in signal cable 54 Cheng Zhong, will be delivered to the signal of detection circuit 52, all be filtered out in addition to voltage signal, detection circuit 52 is believed just for voltage Number it is detected.

In addition, filtering circuit 53 can also set corresponding voltage signal examination criteria, which is to detect electricity The level frequent size of the voltage signal of generation noise is thought on road 52, and filtering circuit 53 can will be less than the voltage of the examination criteria Signal all filters out, and detection circuit 52 is received the voltage signal for reaching examination criteria, so as to improve detection result.

In other embodiments, which can also be responsible for realization by detection circuit 52, and filtering circuit 53 Only it is responsible for voltage signal is entered detection circuit.

In an embodiment of the utility model, which can also connect a counter 56, count Device 56 records the abnormal voltage number of signals that detection circuit 52 detects, can so count time of noise generation The information such as number, location and time, facilitate user to search and solve the problems, such as.

Further, which can also connect a memory 55, and memory 55 is used to store detection circuit Number, time and the ownership side of the 52 abnormal voltage signals detected, the memory 55 can be as the history numbers of record noise According to memory block, user or maintenance personnel is set to carry out analysis noise Producing reason according to the data, it is convenient that image is formed Device 100 is safeguarded.

Such as in the plant-grid connection of image processing system 100, noise is often detected with high-frequency, then on control panel 13 Shown to urge whether user or the ground connection of maintenance personal's check image forming apparatus 100 connect, or mobile image shape Into the place to place of device 100.When noise frequency during as only printed is high, it can be exported with the replacement of display medium or high voltage power supply Bad grade as information.As when specific position noise generation frequency is high, then can only shown to confirm the position or attached Near component connection state.In this way, noise is detected in advance, and prompt message, thereby, it is possible to evade the bad action in part Or the reason for failure.

In addition, when producing bad, by confirming that the noise before bad generation is produced frequency is stored in memory 55 Information, confirm the cause of noise and if noise cause is so the noise of which part, afterwards, can interpolate that and be difficult to The noise cause known it is bad.

Although the description of the several embodiments of the utility model, but these embodiments are intended only as example and propose , it is not intended to limit the scope of the utility model.These new embodiments, can be implemented in a manner of other are various, In the range of the main idea of utility model is not departed from, various omissions, displacement, combination and change can be carried out.These embodiments All it is contained in the scope of the utility model and main idea with its deformation, and it is new to be contained in this practicality described in claims In type and its equivalency range.
