Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is the present invention's part embodiment, instead of whole embodiments. Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 illustrates the schematic block diagram of telltale 100 according to embodiments of the present invention.
As shown in fig. 1, telltale 100 comprises luminescent device 101, drive element 102, detection part 103 and function unit 104.
Drive element 102 is for driving luminescent device 101 luminescence or extinguishes. Here, drive element can drive luminescent device 101 with 100% brightness and to come luminous with other brightness lower than 100% brightness.
Detection part 103 is for detecting the eigenwert of luminescent device 101.According to the eigenwert of luminescent device 101, function unit 104 is for determining that whether luminescent device 101 is normal.
Therefore, according to embodiments of the present invention, telltale 100 has self-checking function, therefore, it is possible in time detection luminescent device can normal luminous or extinguishing, thus improve the security of the application using this telltale and safe rank.
In one example in which, the eigenwert of luminescent device 101 can comprise: luminous intensity, current value and magnitude of voltage. Therefore, detection part 103 can detect at least one in these eigenwerts.
In one example in which, detection part 103 can comprise following at least one: photosensor (not shown), for detecting the luminous intensity of luminescent device 101; Current detecting device (not shown), for detecting the current value of luminescent device 101; With voltage detection device (not shown), for detecting the magnitude of voltage of luminescent device 101.
Here, photosensor can be photovaristor, photodiode or photosensitive triode, or any other suitable device that is existing or exploitation in the future. In order to detect the luminous intensity of luminescent device 101, photosensor can be positioned near luminescent device 101, to receive the visible ray that luminescent device 101 sends.
The number of luminescent device 101 can be one or more. When the number of luminescent device 101 is more than one, detection part 103 can detect the eigenwert of each luminescent device 101 or multiple luminescent device 101 combine after eigenwert.
Specifically, when detection part 103 utilizes photosensor to detect the luminous intensity of luminescent device 101, can arrange that many photosensor the same as the number of luminescent device 101 is to provide the luminous intensity of each luminescent device 101, and can also only arrange several photosensors so that each photosensor provides the luminous intensity after the combination of multiple luminescent device 101. Such as, if multiple luminescent device 101 is arranged with circumferential fashion, the number of photosensor can be 3, the luminous intensity of the luminescent device 101 within the scope of each detection 120 �� of sector region; Or, the number of photosensor can be 4, the luminous intensity of the luminescent device 101 within the scope of each detection 90 �� of sector region. Certainly, it is understood that, multiple arrangement form of luminescent device 101 and the number of photosensor and sensing range are only exemplary, and the embodiment of the present invention is not limited to this, and those skilled in the art suitably can adjust according to design requirement and physical condition in the specific implementation.
In one example in which, when the luminous intensity detected is more than or equal to the 60% of normal value, function unit 104 can think luminescent device 101 normal luminous, otherwise, it is believed that luminescent device 101 is defective and needs to change. Luminescent device 101 is defective may be caused because of the reason such as device aging or damage. Here, normal value can be luminous intensity during single luminescent device 101 normal luminous or luminous intensity sum during multiple luminescent device 101 normal luminous.
In addition, it is also possible to judge whether luminescent device 101 can normally extinguish according to the luminous intensity of luminescent device 101. In one example in which, when the luminous intensity detected be less than or equal normal value 25% time, function unit 104 can think that luminescent device 101 normally extinguishes.
When detection part 103 detects the current value of luminescent device 101, it is possible to use small resistor is used as current detecting device, sample with the electric current to luminescent device 101.Similarly, it is possible to come relative to luminescent device 101 arrange current detection means in the way of many by one_to_one corresponding or one, to detect the current value after the current value of each luminescent device 101 or the combination of multiple luminescent device 101.
In one example in which, when the current value detected be more than or equal to normal value 60% and be less than or equal normal value 140% time, function unit 104 can think luminescent device 101 normal luminous, otherwise, it is believed that luminescent device 101 is defective and needs to change. Here, normal value can be current value during single luminescent device 101 normal luminous, if or multiple luminescent device 101 in parallel, normal value is current value sum during their normal luminous.
In addition, it is also possible to judge whether luminescent device 101 can normally extinguish according to the current value of luminescent device 101. In one example in which, when the current value detected be less than or equal normal value 5% time, function unit 104 can think that luminescent device 101 normally extinguishes.
When detection part 103 detects the magnitude of voltage of luminescent device 101, it is possible to the voltage of luminescent device 101 is sampled. Similarly, it is possible to arrange voltage detection device relative to luminescent device 101 by one_to_one corresponding or one in the way of many, to detect the magnitude of voltage after the magnitude of voltage of each luminescent device 101 or the combination of multiple luminescent device 101.
In one example in which, when the magnitude of voltage detected be more than or equal to normal value 40% and be less than or equal normal value 160% time, function unit 104 can think luminescent device 101 normal luminous, otherwise, it is believed that luminescent device 101 is defective and needs to change. Here, normal value can be magnitude of voltage during single luminescent device 101 normal luminous, if or multiple luminescent device 101 connect, normal value is magnitude of voltage sum during their normal luminous.
In addition, it is also possible to judge whether luminescent device 101 can normally extinguish according to the magnitude of voltage of luminescent device 101. In one example in which, when the magnitude of voltage detected be less than or equal normal value 10% time, function unit 104 can think that luminescent device 101 normally extinguishes.
In one example in which, function unit 104 can judge short circuit and the open circuit fault of one or more luminescent device 101 according to the current value detected and/or magnitude of voltage.
It should be noted that, in actual applications, the mode of connection of one or more luminescent device 101 can have many kinds, such as pure series connection, pure parallel connection or string also Hybrid connections, therefore, normal value for current value and magnitude of voltage can be different according to the mode of connection of luminescent device 101.
According to embodiments of the present invention, detection part 103 can detect the eigenwert of each luminescent device 101, thus function unit 104 can to determine which or which luminescent device 101 one by one abnormal.
Certainly, in actual applications, usual luminescent device 101 is integrated in telltale 100, so once there is abnormal luminescent device 101, no matter its number how, all needs to change whole telltale 100 instead of only changes luminescent device 101. In this case, because only it needs to be determined that luminescent device 101 whether can all normal luminous and do not need to know particular location and the quantity of abnormal luminescent device 101, so in order to simplify circuit layout and reduce cost, under the prerequisite that whole luminescent device 101 is detected, it is possible to only detect the eigenwert after the combination of multiple luminescent device 101.Here, multiple luminescent device 101 can be whole luminescent device 101, it is also possible to be part luminescent device 101. When divide into groups luminescent device 101 to detect each group of luminescent device 101 whether can normal luminous, the number often organizing luminescent device 101 in luminescent device 101 can be identical or different.
In addition, it is one or more that detection part 103 can detect in the luminous intensity of luminescent device 101, current value and magnitude of voltage, and according to one or more in the All Eigenvalues provided or eigenwert, function unit 104 can determine that whether luminescent device 101 is normal. In one example in which, when an indication light device 101 in eigenwert is abnormal, function unit 104 can judge that luminescent device 101 breaks down. But, the present invention is not limited thereto, those skilled in the art can determine according to the demand for security of the characteristic of luminescent device and product to carry out according to which or which eigenwert to judge and priority between eigenwert.
Fig. 2 is the simplification circuit diagram of the internal structure illustrating telltale according to embodiments of the present invention.
As shown in Figure 2, luminous intensity, current value and magnitude of voltage that detection part 103 detects are provided to function unit 104, and after function unit 104 is determined, whether normal for indication light device 101 determination result can be provided to telltale outside, such as use the machine of this telltale, to point out replacing telltale. Here, it is determined that result can indicate which or which luminescent device 101 being positioned at where abnormal, or can also indicate whether that whole luminescent device 101 is all normal.
Circuit in Fig. 2 is only schematic, and eliminates the element unrelated with the embodiment of the present invention.
According to embodiments of the present invention, the self-inspection of telltale can to comprise two modes: stationary state detecting pattern and change state-detection pattern. Below, will be specifically described respectively.
(1) stationary state detecting pattern
In stationary state detecting pattern, the eigenwert that detection part detection luminescent device is under current state.
The state of luminescent device comprises bright state and state of going out.
Such as, when luminescent device is in bright state, such as during normal luminous, whether stationary state detecting pattern detection luminescent device can normal luminous; And when luminescent device be in go out state time, when such as extinguishing completely, stationary state detecting pattern detection luminescent device whether can normally extinguish.
(2) state-detection pattern is changed
In change state-detection pattern, detection part is except the eigenwert under detecting luminescent device and being in current state, also by function unit, luminescent device is switched to another state from current state, and detection part detect further luminescent device be in this another state under eigenwert.
In one example in which, function unit control drive element, so that luminescent device is switched to another one state within a very short time period, at this moment the eigenwert of luminescent device is detected by detection part, and then when the time period expires, luminescent device is switched back to original state again. User's this switching imperceptible, although or feeling but can obviously distinguish the situation being the state different from normal operation state and there will not be telltale flase alarm.
In one example in which, when luminescent device is switched to another one state, it is possible to reduce the luminous quantity/electric current of luminescent device, to alleviate user to the perception degree of switching, less affect detection simultaneously.
Specifically, in telltale, for luminescent device it is crucial that whether can normal luminous, so to the most meaningful thing of user namely when luminescent device be in go out state time its whether may can not be luminous when needed because of damage. So, utilize change state-detection pattern, luminescent device be in go out state time to it by a small area analysis, now luminescent device not luminous or send out low-light, this can not affect the judgement of user, and each eigenwert then detecting luminescent device is to determine that whether luminescent device is normal.
A stationary state detecting pattern can be entered, and hereafter stationary state detecting pattern and change state-detection pattern can alternately periodic duties when luminescent device changes state. For this reason, function unit or drive element can have timing function.
It is in order to call user's attention that telltale sends warning, if but luminescent device breaks down and make can not normal luminous during reporting to the police, although then the function unit in telltale is reported to the police outward, but user can not get alarm message, if not having self-checking function, telltale does not just know that user's (such as outer part device) does not obtain alarm message. At this time, it is possible to can cause great problem, so user must be reminded to take certain action.
According to embodiments of the present invention; self-inspection is carried out by making to enter stationary state detecting pattern when luminescent device changes state; whether normal luminescent device can be detected while telltale gives the alarm; namely check whether luminescent device can transmit alert message to user; so that function unit can know alarm failure; and then the measures such as shutdown, reporting fault, raising alarm level can be taked, this provide higher safe grade.
In one example in which, the discrete component of simulation is utilized to realize function unit.
In another example, utilize unicircuit to realize function unit.
Therefore, according to embodiments of the present invention, telltale 100 can have self-checking function, thus has higher safe grade. Meanwhile, because telltale according to embodiments of the present invention 100 does not need to use back-up device or external detection part to provide the safety performance of reinforcement, so the embodiment of the present invention reduce further cost and system complexity.
Fig. 3 illustrates the schema of the method 300 for carrying out self-inspection by telltale according to embodiments of the present invention.
As shown in Figure 3, in the 301 of method 300, detect the eigenwert of luminescent device by the detection part in telltale. In 302, determine that whether luminescent device is normal by the function unit in telltale according to the eigenwert of luminescent device.
According to embodiments of the present invention, therefore, pass through self-checking function, it is possible in time detection luminescent device can normal luminous or extinguishing, thus improve the security of the application using this telltale and safe rank.
As mentioned above, it is necessary, detection part can comprise following at least one: photosensor, for detecting the luminous intensity of luminescent device; Current detecting device, for detecting the current value of luminescent device; And voltage detection device, for detecting the magnitude of voltage of luminescent device.
In method 300, detection part can detect in stationary state detecting pattern and change state-detection pattern, at stationary state detecting pattern, and the eigenwert that detection part detection luminescent device is under current state;In change state-detection pattern, detection part is except the eigenwert under detecting luminescent device and being in current state, also by function unit, luminescent device is switched to another state from current state, and detection part detect further luminescent device be in this another state under eigenwert.
Therefore, according to embodiments of the present invention, telltale can have self-checking function, thus has higher safe grade. Meanwhile, because telltale according to embodiments of the present invention does not need by aforesaid method to use back-up device or external detection part to provide the safety performance of reinforcement, so the embodiment of the present invention reduce further cost and system complexity.
