Description

Technical Field

[0001] The present invention relates to the field of sensor measurement technology, and in particular to a demisting system for a transceiver-integrated sensor. Background Art

[0002] With the advent of the information age, the use of information is becoming increasingly widespread. Acquiring accurate and reliable information is paramount in this process. Transceiver sensors are a primary means of acquiring information in the natural world and production. Photoelectric transceivers are one type of integrated transceiver, converting optical signals into electrical signals. They typically consist of a light emitter and a light receiver. In practice, these sensors are often protected by lenses. However, in practice, these lenses can fog up in low-temperature environments or when exposed to sudden low temperatures, resulting in inaccurate voltage readings from the sensor. Summary of the Invention

[0003] In response to the above technical problems, the technical solution adopted by the present invention is: a defog system for an integrated transceiver sensor, the system including an integrated transceiver sensor, a detection object, a processor and a memory storing a computer program, the integrated transceiver sensor having a transmitting window and a receiving window, the transmitting window including a first mirror for protection, and the receiving window including a second mirror for protection.

[0004] The light beam emitted by the emitting window is transmitted through the first mirror to the detection object, and is reflected by the second mirror to the receiving window after diffuse reflection. The receiving window converts the received light signal into a voltage value.

[0005] When a processor executes a computer program, it performs the following steps:

[0006] S100 , obtaining an ambient temperature T1 and a mirror surface temperature T2 , where the mirror surface temperatures are used to represent the temperatures of a first mirror surface and a second mirror surface.

[0007] S200, obtaining the mirror temperature difference T=T1-T2.

[0008] S300, when T 02 >T≥T 01 When the first mirror and the second mirror are heated, T 01 is the first preset temperature difference threshold, T 02 is the second preset temperature difference threshold.

[0009] S400, after heating the first mirror and the second mirror, obtain a first voltage value list V={V1, V2, ..., V i ,…,Vm}, V i is the voltage value when heating for i seconds, and the value of i ranges from 1 to m.

[0010] S500, if V0-V m <V t , stop heating, where V0 is the voltage value converted from the light signal received by the receiving window under preset conditions, V t is the preset voltage difference threshold.

[0011] S600, if V0-V m ≥V t , issue an alarm.

[0012] The present invention has at least the following beneficial effects: In summary, the present invention obtains the ambient temperature and the mirror temperature, and obtains the temperature difference between the ambient temperature and the mirror. When the mirror temperature difference is greater than a second preset temperature difference threshold but not greater than a first preset temperature difference threshold, the first and second mirrors are heated, and a list of voltage values ​​within a first preset time period is obtained. When the voltage value at the time point corresponding to the first preset time period differs from the voltage value received under preset conditions by a preset voltage difference threshold, heating is stopped, and it is considered that the fog caused by the mirror temperature difference has been cleared. When the voltage value at the time point corresponding to the first preset time period differs from the voltage value received under preset conditions by a preset voltage difference threshold, an alarm is issued. Thus, fog caused by the temperature difference in the transceiver sensor is evaporated during heating, achieving the defogging function of the transceiver sensor. If the voltage value at the time point corresponding to the first preset time period differs from the voltage value received under preset conditions by a preset voltage difference threshold, it indicates that the low voltage value is not caused by fog due to the temperature difference, and an alarm is issued, prompting personnel to observe and resolve the problem.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figure 1-4 As shown, an embodiment of the present invention provides a defogging system for an integrated transceiver sensor, the system comprising an integrated transceiver sensor 1, a detection object 2, a processor and a memory storing a computer program, the integrated transceiver sensor 1 having a transmitting window 8 and a receiving window 9, the transmitting window 8 including a first mirror 3 for protection, the receiving window 9 including a second mirror 4 for protection.

[0022] The light beam emitted by the emission window 8 is transmitted through the first mirror 3 to the detection object 2, and is reflected by the second mirror 4 to the receiving window 9 after diffuse reflection. The receiving window 9 converts the received light signal into a voltage value.

[0023] When a processor executes a computer program, it performs the following steps:

[0024] S100 , obtaining an ambient temperature T1 and a mirror surface temperature T2 , where the mirror surface temperature is used to represent the temperature of the first mirror surface 3 and the second mirror surface 4 .

[0025] Specifically, the ambient temperature is the temperature of the external space of the shell where the transceiver sensor 1 is located. It can be understood that when the transceiver sensor 1 is placed in a certain indoor space, the ambient temperature is the indoor temperature; when the transceiver sensor 1 is placed outdoors, the ambient temperature is the outdoor temperature of the area on that day.

[0026] Furthermore, the ambient temperature T1 may be obtained through manual input.

[0027] In another embodiment of the present invention, the ambient temperature is the temperature inside the housing where the transceiver integrated sensor 1 is located.

[0028] Furthermore, when the ambient temperature is the temperature inside the housing of the transceiver sensor 1 , a first transceiver temperature sensor that has been tested normally is installed inside the transceiver sensor 1 , and the ambient temperature T1 is obtained through the first transceiver temperature sensor that has been tested normally.

[0029] Furthermore, when the ambient temperature is the temperature inside the housing where the transceiver sensor 1 is located, the first transceiver temperature sensor that is tested normally is obtained by the following steps:

[0030] S1001 , placing the transceiver integrated sensor 1 including the first transceiver integrated temperature sensor under a first preset temperature TP1 and a second preset temperature TP2 .

[0031] Specifically, the first preset temperature is greater than 35 degrees Celsius, and the second preset temperature is less than -5 degrees Celsius.

[0032] S1002, the processor receives a first detection temperature TV1 and a second detection temperature TV2 emitted by a first transceiver integrated temperature sensor, wherein the first detection temperature is a temperature detected when the first transceiver integrated temperature sensor is placed at a first preset temperature, and the second detection temperature is a temperature detected when the first transceiver integrated temperature sensor is placed at a second preset temperature.

[0033] S1003 , when |TP1-TV1|<preset difference threshold and |TP2-TV2|<preset difference threshold, it is determined that the test of the first transceiver integrated temperature sensor is normal; otherwise, it is determined that the test of the first transceiver integrated temperature sensor is abnormal.

[0034] Specifically, the mirror surface temperature T2 is obtained by a second transceiver-in-one temperature sensor that is in close contact with the mirror surface.

[0035] In one embodiment of the present invention, the mirror temperature T2 is obtained as follows:

[0036] S010, obtain a temperature list D = {D1, D2, ..., D r ,…,D s}, D r is the temperature of the rth collected mirror point, the value range of r is 1 to s, and s is the number of collected mirror points.

[0037] Specifically, those skilled in the art know that any method of obtaining the temperature of multiple mirror points in the prior art falls within the scope of protection of the present invention. For example, multiple integrated transceiver temperature sensors are set on the first mirror 3 and the second mirror 4 to obtain the temperature of the first mirror 3 and the temperature of multiple mirror points on the second mirror 4.

[0038] S020, obtain T2=min{D1, D2, ..., D r ,…,D s}.

[0039] In another embodiment of the present invention, S020 is replaced by S030, wherein S030: obtain T2=(1 / s)∑ s r=1 D r .

[0040] S200, obtaining the mirror temperature difference T=T1-T2.

[0041] S300, when T 02 >T≥T 01 When the first mirror surface 3 and the second mirror surface 4 are heated, T 01 is the first preset temperature difference threshold, T 02 is the second preset temperature difference threshold.

[0042] Specifically, when T 02 >T≥T 01 It can be understood that the first mirror surface 3 and the second mirror surface 4 are fogged.

[0043] Specifically, such as Figure 2 As shown, the first mirror surface 3 and the second mirror surface 4 are heated using a heating resistance wire 5 .

[0044] In another embodiment of the present invention, Figure 3 As shown, the first mirror surface 3 is heated by using the first ITO thin film heater 6 , and the second mirror surface 4 is heated by using the second ITO thin film heater 7 .

[0045] S400, after heating the first mirror 3 and the second mirror 4, obtain a first voltage value list V={V1, V2, ..., V i ,…,V m}, V i is the voltage value when heating for i seconds, and the value of i ranges from 1 to m.

[0046] S500, if V0-V m <V t , stop heating, where V0 is the voltage value converted from the light signal received by the receiving window 9 under preset conditions, V t is the preset voltage difference threshold.

[0047] Specifically, the preset conditions are that the indoor temperature is 25° C. and the indoor humidity is between 30% and 80%.

[0048] Specifically, if V0-V m <V tIt can be understood that as the first mirror 3 and the second mirror 4 are heated, the fog on the first mirror 3 and the second mirror 4 gradually evaporates, so that the first mirror 3 and the second mirror 4 become clearer, the light signal reflected to the receiving window 9 through the second mirror 4 is stronger, and the converted voltage value is stronger; it can be known that if the voltage value caused by the fog due to the temperature difference is reduced, as the first mirror 3 and the second mirror 4 are heated, the voltage value will tend to increase to the voltage value converted by the light signal received by the receiving window under the preset conditions.

[0049] S600, if V0-V m ≥V t , issue an alarm.

[0050] Specifically, the transceiver integrated sensor 1 can issue an alarm by emitting an alarm tone.

[0051] In summary, the present invention obtains the ambient temperature and the mirror temperature, and obtains the temperature difference between the ambient temperature and the mirror. When the mirror temperature difference is greater than the second preset temperature difference threshold and not greater than the first preset temperature difference threshold, the first mirror and the second mirror are heated, and a list of voltage values ​​within the first preset time period is obtained. When the voltage value at the time point corresponding to the first preset time period differs from the voltage value received under the preset conditions by a preset voltage difference threshold, heating is stopped, and it is considered that the fog caused by the mirror temperature difference has been cleared. When the voltage value at the time point corresponding to the first preset time period differs from the voltage value received under the preset conditions by more than the preset voltage difference threshold, an alarm is issued. Thus, the fog caused by the temperature difference in the transceiver sensor is evaporated during heating, realizing the defogging function of the transceiver sensor. If the voltage value at the time point corresponding to the first preset time period differs from the voltage value received under the preset conditions by more than the preset voltage difference threshold, it indicates that the low voltage value is not caused by fog due to the temperature difference. At this time, an alarm is issued, prompting staff to observe and resolve the problem.

[0052] In addition, the present invention performs heating when the mirror temperature difference is large, so that the transceiver integrated sensor can operate at a lower temperature, thereby improving the tolerance at lower temperatures.

[0053] Furthermore, when the heating resistance wire 5 is used to heat the first mirror surface 3 and the second mirror surface 4, the first preset time period m is obtained by the following steps:

[0054] S001, obtain the heating time period m1 = c•w•T•(1+a) / (I 2 •R), c is the specific heat capacity of the mirror, w is the mass of the first mirror 3 and the second mirror 4, a is the heat loss factor, I is the current in the heating resistance wire 5, R is the resistance of the heating resistance wire 5, wherein the heating time m1 is the time it takes for the temperature of the first mirror 3 and the second mirror 4 to rise from T2 to T1.

[0055] Specifically, the heat loss factor a can be determined according to actual conditions.

[0056] In another embodiment of the present invention, the heating time period m1 is obtained by the following steps:

[0057] S0011, divide the first mirror surface into x·y rectangles.

[0058] S0012, obtain the first rectangular heating time period p1 = c·w1·T / (I 2 •R), the first rectangular heating time period is the time it takes for the temperature of the rectangle where the heating resistance wire is located to rise from T2 to T1.

[0059] S0013, obtain the cumulative heating time p corresponding to the qth column of the first mirror q =q•p1+(q-1)p0, where q ranges from 1 to y. The cumulative heating time corresponding to the qth column of the first mirror is the time it takes for the temperature of the rectangles in the qth column of the first mirror to rise from T2 to T1. p0 is the time required for the heating resistance wire to lose heat during the heat transfer process of each row of rectangles.

[0060] Specifically, the time required for heat loss during the heat transfer process of each row of rectangular shapes generated by the heating resistance wire is an empirical value, which can be obtained by taking the average value through multiple tests.

[0061] S0014, obtain the heating time period m1==y•p1+(y-1)p0.

[0062] In summary, the present invention divides the first mirror surface into x•y rectangles. After the temperature of the rectangle where the heating resistor wire is located rises to T1, heat propagation is performed, and finally the temperature of the yth column of the first mirror surface rises to T1. By calculating the temperature rise time of the rectangle where the heating resistor wire is located and the time lost during the propagation process, the time for the entire mirror surface of the first mirror surface to be heated to T2 is obtained, and the obtained time is more accurate.

[0063] S002 , obtaining a preset evaporation time period m2 , where the preset evaporation time is the time required for the mist on the first mirror surface 3 and the second mirror surface 4 to evaporate into water vapor when the temperature is at T2 .

[0064] Specifically, the preset evaporation time m2 is a preset empirical value.

[0065] S003, obtaining a preset observation time period m3, where the preset observation time is used to observe whether the voltage value is in a stable state.

[0066] Specifically, the preset observation time m3 is obtained as follows:

[0067] S31, initialize m3=m30 , where m 30 is the initial observation time.

[0068] S32, obtain the event list E={E1, E2, ..., E g ,…,E z}, E g It is the g-th event of mirror temperature difference in the historical time period. The value of g ranges from 1 to z, and z is the total number of events of mirror temperature difference in the historical time period.

[0069] S33, obtain the voltage value in E at m0=m1+m2+m 30 The quantity U1 that is in a stable state at all times.

[0070] The voltage value is in a stable state when the voltage value is within the range of the first preset stable voltage to the second preset stable voltage, and the first preset stable voltage is V0-V t , the second preset stable voltage is V0+V t .

[0071] S34, when U1 / z>U0, m 30 Denoted as m3, where U0 is the preset stable voltage quantity ratio threshold.

[0072] S35, when U1 / z≤U0, m3=m3+m t , execute S032, where m t is the preset time growth factor.

[0073] Based on S31-S35, m0 is initialized, and a list of events in which mirror temperature difference occurs within the historical time period is obtained. The voltage value in the event list at the current observation time is obtained, and the events in which the voltage value is in a stable state are obtained. When the proportion of events in which the voltage value is in a stable state meets the preset number ratio, the current observation time is recorded as the preset observation time, so as to find the most reasonable preset observation time.

[0074] S004: Obtain a first preset time period m=m1+m2+m3.

[0075] In summary, the heating time, the preset evaporation time and the preset observation time are obtained, and the heating time, the preset evaporation time and the preset observation time are added together to obtain the first preset time period. By dividing the evaporation of fog on the first mirror and the second mirror of the transceiver sensor into three steps, the first preset time period can be obtained more accurately.

[0076] The present invention further includes in S300:

[0077] S301, when T≥T 02When the first mirror surface 3 and the second mirror surface 4 are heated.

[0078] Specifically, when T ≥ T 02 It can be understood that the water vapor in the air condenses on the surfaces of the first mirror surface 3 and the second mirror surface 4, that is, frost forms on the surfaces of the first mirror surface 3 and the second mirror surface 4.

[0079] S302, after heating the first mirror 3 and the second mirror 4, obtain a second voltage value list B={B1, B2, ..., B j ,…,B n}, B j is the voltage value when heating for j seconds, and the value of j ranges from 1 to n.

[0080] Specifically, the second preset time period n is obtained by the following steps:

[0081] S3021, obtain the second heating time n1 = c•w•(273.15-T2)•(1+a) / (I 2 •R), the second heating time is the time it takes for the temperature of the first mirror 3 and the second mirror 4 to rise from T2 to 273.15K.

[0082] Specifically, the second heating time is the time it takes for the temperature of the first mirror 3 and the second mirror 4 to rise from T2 to 273.15K (ie, 0 degrees Celsius), that is, the second heating time is the time it takes for the solid frost on the first mirror 3 and the second mirror 4 to liquefy.

[0083] S3022, obtain the third heating time n2 = c•w•(T1-273.15)•(1+a) / (I 2 •R), the second heating time is the time it takes for the temperature of the first mirror 3 and the second mirror 4 to rise from 273.15K to T1.

[0084] S3023, obtaining a second preset time period n=n1+n2+m2+m3.

[0085] S303, if V0-B n <V t , stop heating.

[0086] S304, if V0-V m ≥V t , issue an alarm.

[0087] In summary, when the mirror temperature difference is not less than the second preset temperature difference threshold, the first mirror and the second mirror are heated, and a second voltage value list within the second preset time period is obtained. If the difference between the voltage value at the time point corresponding to the second preset time period and the voltage value under the preset conditions is within the preset range, heating is stopped; otherwise, an alarm is issued, so that the frost on the transceiver sensor caused by the temperature difference evaporates during heating, thereby realizing the automatic defrosting function.

[0088] Furthermore, the present invention further comprises the following steps:

[0089] S91, obtaining the node voltage value VS1 at the current time.

[0090] S92, when V0-VS1>V t When the first mirror surface 3 and the second mirror surface 4 are heated for a first preset time period m.

[0091] Specifically, when V0-VS1>V t It can be understood that the first mirror surface 3 and the second mirror surface 4 may be fogged, or the first mirror surface 3 or the first mirror surface 4 may be blocked.

[0092] S93, obtaining a voltage value VS2 after heating for a first preset time period m.

[0093] S94, when V0-VS2<V t When the temperature reaches 0, the heating is stopped; otherwise, an alarm is issued.

[0094] Specifically, when V0-VS2<V t It can be understood that the first mirror 3 and the second mirror 4 are determined to be fogged, and after the first mirror 3 and the second mirror 4 are heated for the first preset time period m, the fog on the first mirror 3 and the second mirror 4 dissipates, and the voltage value after heating for the first preset time period returns to the voltage value under the preset conditions.

[0095] In summary, by obtaining the voltage value VS1 of the current time node, when the difference between the voltage value of the current time node and the voltage value converted from the light signal received by the receiving window under the preset conditions is greater than the preset voltage difference threshold, the first mirror and the second mirror are heated for the first preset time period m, and the voltage value after heating for the first preset time period m is obtained. When the difference between the voltage value after heating for the first preset time period m and the voltage value converted from the light signal received by the receiving window under the preset conditions is less than the preset voltage difference threshold, heating is stopped, otherwise an alarm is issued. Through the above steps, another way to detect fog or frost is obtained to realize defogger of the transceiver integrated sensor.

[0096] Although some specific embodiments of the present invention have been described in detail by way of example, it will be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will also be understood by those skilled in the art that various modifications may be made to the embodiments without departing from the scope and spirit of the present invention.
