Using Active Opto diffuse Special requirements for protection devices (AOPDDR) equipment

1 Scope

This section provides sensing using active optoelectronic protective devices diffuse (AOPDDRs), for mechanical safety of electro-sensitive prevention Additional requirements for protective equipment (ESPE) the design, manufacture and testing. For those who reach the appropriate means to ensure the safety performance requirements given special s concern. ESPE may include optional safety function, select functional requirements in this section in Appendix A and GB/T 19436.1- 2004 Appendix A are given. This section is limited to ESPE function, it does not specify the size or the layout and structure of the detection zone in any particular application to hazardous parts, Nor any provision constitute a dangerous state machinery. AOPDDR detection device is a two-dimensional detection zone. By the transmitter element emits near infrared radiation detection zone when the light emitted Encountered an object (such as a human body or partial), part of the radiation reflected by a diffuse way to the receiver, which can be detected in the region object. Note. In some cases, the need to consider the limitations of the sensor in use. E.g. --- Produces specular reflection (special) objects, if its value is less than the predetermined value diffuse "black" test piece, the object may not be detected; The minimum reflectance --- obstacle detection is based on people's clothing to determine. When the reflectance is lower than the estimated value of the object of this section, the object is May not be detected. This section does not apply to radiation wavelength AOPDDR beyond 820nm ~ 946nm range, and not by its own light emission Those AOPDDR. For radiation wavelength outside the range of the sensor, this section can be used as a guideline.

3 Terms and Definitions

GB/T 19436.1-2004 after Chapter 3, by the following terms and definitions apply to this supplement. 3.301 By the optical transmitting and receiving device sensing element is completed. Detected by the detection zone specified in two dimensions in the range of the device Optical radiation generated when objects appear diffuse. 3.302 In the detection zone to detect the specified test piece (see 4.2.13) capabilities. 3.303 Located in an area outside the detection zone, the detection zone in the region to detect the specified test piece (see 4.2.13) must meet the requirements of the probability need. 4 function, design and environmental requirements GB/T 19436.1-2004 corresponding content section after the adoption of the following substitutions and additions are applicable to this section. 4.11) functional requirements 4.1.3 ESPE Type This section considers only the first three types of ESPE. Supply and/or user equipment shall be responsible for this type is suitable for special applications Make provisions. Type 3 ESPE shall meet the requirements of this section 4.2.2.4 for fault detection. In normal operation, when the sensing device is actuated or off Power-up, such ESPE at least two output signal switching devices (OSSDs) in each output circuit should become OFF state. Note. GB/T 19436.1-2004 provisions in 4.1.3 after replacing the above apply to this section. 1) lack of item, such as 4.1.1,4.1.2,4.2.1,4.2.2.1,4.2.2.2,4.2.2.4,4. 2.2.5,4.2.3 4.2.11,4.3.1 ~ ~ 4.3.4,5.1.1.1, 5.1.2.1,5.1.3,5.2.2 ~ ~ 5.4.5 5.2.8,5.3,5.4.1 see GB/T 19436.1-2004 . 4.1.4 detection capability restricted area In the detection plane, the light from the window and the distance between its recent detection zone boundary should not exceed 50mm. Detection capability is an area restricted area and the starting point of the detection zone between the light window. In order to ensure that a particular application since the detection area and the light window Exists between this region and cause a hazard, the supplier shall provide the appropriate information and the size of the region. 4.2 Design Requirements 4.2.2 Fault detection requirements 4.2.2.2 Particular requirements for the type 1ESPE GB/T 19436.1-2004 present terms is not applicable here. 4.2.2.3 Particular requirements for the type 2ESPE GB/T 19436.1-2004 present terms is not applicable here. 4.2.2.4 Particular requirements for the type 3ESPE Because when a single failure of sensitive devices caused AOPDDR detection capability previously described completely lost, it should make ESPE in Regulation GB 19436.3-2008/IEC 61496-3.2001 Within the given response time to enter the locked state. Note 1. The spin mirror scans the detection zone AOPDDR, located by scanning a predetermined reference detection zone and the tolerance zone outside will be able to meet this requirement. When the single fault occurs resulting in reduced above AOPDDR detection capability, should make ESPE into the locked within 5s after failure status. Note 2. AOPDDR detection capability reduces examples. --- Minimum detectable object size increases; --- Reflectance minimum detectable object is increased; --- Detection accuracy is reduced. When the single fault resulting in increased response time exceeds a predetermined value, or at least to prevent the OSSD to enter a disconnected state, should make ESPE Now enter the locked state. For example, within the response time specified, or the fault detection requirements of state changes in accordance with the requirements of the following events stand It enters a locked state. --- Activate the sensor function; --- Off/on switch; --- Start interlock or the restart interlock reset (if so, see GB/T 19436.1-2004 in A.5 and A.6); --- Using an external test signal (if any). Note 3. In special applications, the sensor function is activated if the frequency is low and only change when the state was only monitored OSSD, you may need an external test signal. When the locked state caused by the fault persists, even through the main power supply is interrupted and then restored, or other means, should not make ESPE Leaving the locked state is reset. If ESPE does not cause a dangerous failure of a single fault is not detected, there should not be other failures caused by failure to danger. Correct Verify this requirement, see 5.3.4. Note. GB/T 19436.1-2004 provisions in 4.2.2.4 after replaced by the above apply to this section. 4.2.2.5 Particular requirements for the type 4ESPE GB/T 19436.1-2004 of this clause do not apply to this section. Integrity 4.2.12 AOPDDR detection capability 4.2.12.1 Overview AOPDDR should be designed to ensure that their supply-side detection capability of not less than the limits specified in this part of the middle finger of any of the following. --- Aging element; --- Component tolerances (e.g.,. the spectral sensitivity of the receiving member); --- Distance dependent sensitivity change, such as those relating optical sensitivity; --- Adjustment limit; --- AOPDDR unreliable internal optical and mechanical parts of the installation; --- Environmental interference, in particular. a) the system noise; b) in line with GB/T electrical interference 4.3.2 specified 19436.1-2004; c) contamination on the surface of the optical window of the housing; d) condensing on the surface of the optical window of the housing; e) ambient temperature; f) ambient light; g) Background (for example. the contrast between the background and the object); h) vibration and shock; i) humidity; j) supply voltage variations and interruptions. If a single fault (in GB/T 19436.1- under normal operating conditions (see GB/T 19436.1-2004 in 5.1.2.1) appears GB 19436.3-2008/IEC 61496-3.2001 2004 specified in Appendix B), will not cause the loss of AOPDDR detection capability; but if the combination occurs when the above conditions will result in the ability to detect funeral Loss, we should put this together with a combination of the fault together as a single fault conditions, and for such a single fault AOPDDR should make as 4.2.2.4 the desired reaction. Note. the reference target scanning technology can be used to meet the requirements related to component aging, can also be used to give the same level of assurance other technologies. 4.2.12.2 detection and tolerance zone The supplier shall define the tolerance zone. Predetermined tolerance zone, the supplier shall consider the worst conditions, for example, should include full consideration to this Part Effect portion, and any additional influence (environmental impact, component failure, etc.) for the rear side of the predetermined S/N ratio and the standard deviation σ. Tolerance zone with the system interference, measurement error, measurement criteria, etc. depending on the value. But also to ensure the detection range in the detection zone is necessary. Fig. 1a) and 1b) of the detection zone, for example. Throughout the detection zone, the test piece (see 4.2.13) to minimize the probability of detection 1 ~ 2.9 × 10-7 is detected. In order to achieve the minimum detection The probability of tolerance zone to be attached to the detection zone (see Appendix BB in FIG BB.2). Note 1. The probability of detection is used in this part of the measurement accuracy of the decision, regardless of the probability of failure. Note 2. Pay special attention when AOPDDR detection zone by more than one transmitting and/or receiving units, to ensure that these transmitting and/or receiving unit, as the Nakano detection capability between the detection zone is not limited. The detection zone and the tolerance interval limits should be measuring the midpoint of the distribution of values, reflectivity test piece used for the measurement should be equal to or between "black" Between the specimen and the "white" test block. Reflectance supplier shall declare the test piece used and calculations. This requirement is met by checking supplier declaration verification. Note 3. The value of the tolerance zone and ranging accuracy is not necessarily constant, for example, it can be a function of the distance measurement. Note 4. If AOPDDR automatic setting means its detection zone, in determining the tolerance zone should be considered when setting ranging error value (see A.11). Note 5. Appendix BB gives additional information on the relationship between ranging accuracy and detection probability. 4.2.12.3 Scanning geometry, scanning frequency and response time The supplier shall define the scope and parameters including the scanning angle, including the relevant detection zone. Scanning geometry and/or scanning frequency should be fully guaranteed The minimum detectable object size of the diameter of the test block certificate provisions, the maximum range of the detection area can be detected. For only in 50mm ~ The minimum value of a predetermined object size AOPDDR detectable within a range of 100mm. The minimum detectable size from the line of sight of the object Off may be. Note 1. The minimum detectable object size limits within the range of 50mm ~ 100mm, is based on the current application. For the detection capabilities beyond the scope of this The AOPDDR may require additional requirements. Or stationary object in the detection zone at a speed of not more than 1.6m/s motion minimum detectable size, response time should be within the prescribed ESPE to be detected. Response time should be for the consideration determined under worst-case conditions, especially for scanning frequency and object movement. As for When the party AOPDDR provisions can be used to detect movement speed is greater than 1.6m/s object, at any speed, including the maximum speed of its provisions Degree, these requirements should be met. Note 2. The detection capability can be determined AOPDDR optical geometry to the specific design, a whole bundle of light shines in the maximum range of the detection zone and the tolerance zone Test block. If this is the case, the distance between adjacent light-emitting center between the two beams (except bunch of first beam and last) will not exceed half of the test piece straight path. For other designs, it will be difficult to achieve by 5.2.1.2 and 5.2.11 to verify, in particular in accordance with the above requirements to consider moving object. Note 3. Appendix AA. 5 shows an example of calculating the response time. Boundary detection zone from any point projected onto the light-receiving element AOPDDR, all points on its trajectory should be in the detection zone (see 4.2.12.2) or detection capability restricted area (see 4.1.4) inside. 4.2.13 type test specimen 4.2.13.1 Overview Test block is part AOPDDR, so Chapter 5 specimen type used in the test, provided by the supplier. Type test block should be marked Type reference designations and intended for use with AOPDDR identification mark. The diameter of the test piece shall be equal to the specified maximum detection capability (ie, minimum diameter). Depending AOPDDR detection capabilities, perhaps you need To test within the range of 50mm ~ 100mm diameter other block. Note. For ease of use, is usually the minimum effective length of the test piece. GB 19436.3-2008/IEC 61496-3.2001 4.2.13.2 black test piece Black test piece shall be a minimum of 0.3m effective length of the cylinder. Diffuse value test piece surface under normal conditions wave transmitter Testing should be long within 1.6 to 2.0% range, including the values, including the measurement accuracy. This value should be verified by testing. When the count Operators used in this reflection should take 1.8% of the value of the calibration values. NOTE. Figure 2 shows the black test piece to determine the value of a reflection survey. 4.2.13.3 white test block White specimen shall be a minimum of 0.3m effective length of the cylinder. Diffuse reflectance values of the test piece surface emitter wavelengths should Within the range of 80% to 90%. 4.2.13.4 back reflection test block Retro-reflective test piece shall be a minimum of 0.3m effective length of the cylinder. Specimen surface should be retro-reflective material. The reflective material should Compliance with EN471 Class 2 or an equivalent post reflective material requirements. NOTE. EN471 Table 5 defines the minimum coefficient of retroreflection class 2 material is 330cd · lx-1 · m-2, its incident angle is 5 °, observation angle of 0.2 ° (12 '). 4.2.14 Wavelength AOPDDRs should work within 820nm ~ 946nm wavelength range. NOTE. This wavelength range is based on components and research currently available, studies show this wavelength range suitable for the clothing materials used. 4.2.15 radiation intensity Even in the case of component failure, producing and intensity of the radiation emitted by AOPDDR should never exceed GB/T 7247.1-2001 Class 1 laser for maximum power or energy levels of 9.3, 9.4 and specified in Table 1. Class 1 laser for identification shall be GB/T 7247.1-2001 5.2 regulations. 4.2.16 mechanical structure If you change the component position will lead to a reduced ability to detect and below the limits specified in the supplier, then the fixing member should not rely on friction Rub force. NOTE. Use the elliptical mounting holes without additional means, such as by the impact and other mechanical disturbance will lead to changes in the position of the detection zone. 4.3 Environmental Requirements Note. These requirements may not satisfy some of the needs of the application (for example, use in a vehicle, including automated guided vehicles (AGVs), forklifts, machinery, and other activities). 4.3.1 ambient air temperature and humidity range Even experienced rapid changes in temperature and humidity cause condensation surface light window fogging, ESPE there should be no danger.
