[0002] As is well known, pulverized coal boilers improve the combustion rate of coal, are highly efficient and energy-saving, and are easy to start and stop, and are widely used in various fields. Existing pulverized coal boilers include a furnace body, a pulverized coal silo, and a bag filter. The pulverized coal silo is equipped with a discharge port and a discharge port, while the furnace body is equipped with a feed port and an air outlet. The discharge port of the pulverized coal silo is connected to the feed port of the furnace body through a connecting pipe, and the air outlet of the furnace body is connected to the bag filter through a ventilation pipe. Among them, the pulverized coal silo is a fuel transfer station. For boilers with intermediate storage feeding, there are both coal silos and pulverized coal silos.

[0003] Currently, all pulverized coal silos are equipped with reversing baffles. The pulverized coal is fed into the silo by switching the reversing baffles. However, there have been instances where the reversing baffles of the pulverizing system that need to feed pulverized coal have switched to the pulverized coal feeding position, but the actual position of the reversing baffles has not switched to the target pulverized coal silo, resulting in pulverized coal leakage incidents, which seriously affect environmental hygiene and the stable operation of the unit.

[0004] Therefore, how to provide a method for monitoring the reversing baffle of the pulverized coal silo is a technical problem that needs to be solved. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0053] like Figure 1 As shown, an embodiment of the present invention discloses a switching method for a reversing baffle in a pulverized coal silo, the method comprising:

[0054] S110: When a reversing baffle switching request is received, the first operating state of the first infrared light sensing device installed on the reversing baffle is collected, and the second operating state of the second infrared light sensing device installed on the target powder hopper is collected.

[0055] In this embodiment, when the pulverized coal bin needs to feed pulverized coal into another pulverized coal bin, it will receive a switching request for the reversing baffle, thereby realizing the transportation of pulverized coal to other pulverized coal bins. At this time, the first operating state of the first infrared light sensing device and the second operating state of the second infrared light sensing device are collected, that is, whether the first infrared light sensing device and the second infrared light sensing device are in the on state, to ensure that the first infrared light sensing device and the second infrared light sensing device can emit infrared light normally, and to ensure normal monitoring of the reversing baffle.

[0056] S110: When both the first operating state and the second operating state meet the preset conditions, the first infrared light is emitted from the first infrared light sensing device to the second infrared light sensing device, and when the second infrared light sensing device receives the first infrared light, a number of continuous potential signals are generated.

[0057] In some embodiments of this application, after both the first running state and the second running state meet preset conditions, the method further includes:

[0058] Acquire the first position information of the first infrared light sensing device installed on the reversing baffle, and acquire the second position information of the second infrared light sensing device installed on the target powder hopper;

[0059] The distance between the first infrared light sensing device and the second infrared light sensing device is calculated based on the first location information and the second location information.

[0060] In some embodiments of this application, a second infrared light is emitted from the first infrared light sensing device to the second infrared light sensing device;

[0061] When the second infrared light sensing device receives the second infrared light, it emits a third infrared light towards the first infrared light sensing device;

[0062] The first phase difference when the first infrared light sensing device emits the second infrared light to the second infrared light sensing device is detected, and the second phase difference when the first infrared light sensing device receives the third infrared light is detected. The distance between the first infrared light sensing device and the second infrared light sensing device is calculated based on the first phase difference and the second phase difference.

[0063] In this embodiment, when both the first and second operating states meet preset conditions, that is, when both the first and second infrared light sensing devices can normally emit or receive infrared light, the first infrared light sensing device emits second infrared light to the second infrared light sensing device. When the second infrared light sensing device receives the second infrared light, it emits third infrared light to the first infrared light sensing device in real time. By detecting the first phase difference when the first infrared light sensing device emits the second infrared light to the second infrared light sensing device and the second phase difference when the first infrared light sensing device receives the third infrared light, the distance between the first and second infrared light sensing devices is calculated. It should be understood that the phase difference is the time delay caused by the reflection or refraction of light. By calculating the distance between the first and second infrared light sensing devices, this invention can provide reliable data support for determining whether the reversing baffle has been completely switched to the target powder hopper.

[0064] It should be noted that when the second infrared light sensor receives the first infrared light, it generates several consecutive potential signals. As the first infrared light sensor and the second infrared light sensor get closer or farther apart, the potential signals will also increase or decrease accordingly. Therefore, several consecutive potential signals can be generated. When the second infrared light sensor and the first infrared light sensor are in the same position, the potential signals no longer change and the potential signals are zero.

[0065] In some embodiments of this application, the distance between the first infrared light sensing device and the second infrared light sensing device is calculated according to the following formula:

[0066] A = kX(b+c) / 2;

[0067] Where A is the distance between the first infrared light sensing device and the second infrared light sensing device, k is the speed of light propagation, b is the first phase difference, and c is the second phase difference.

[0068] In some embodiments of this application, before determining whether the reversing baffle has completely switched to the target powder hopper based on the potential signal, the method further includes:

[0069] The duration of the potential signal is set according to the distance A between the first infrared light sensing device and the second infrared light sensing device.

[0070] A preset distance matrix B is defined as B(B1, B2, B3, B4), where B1 is the first preset distance, B2 is the second preset distance, B3 is the third preset distance, and B4 is the fourth preset distance, and B1 < B2 < B3 < B4.

[0071] The preset potential signal duration matrix C is set as C(C1, C2, C3, C4, C5), where C1 is the first preset potential signal duration, C2 is the second preset potential signal duration, C3 is the third preset potential signal duration, C4 is the fourth preset potential signal duration, and C5 is the fifth preset potential signal duration, and C1 < C2 < C3 < C4 < C5.

[0072] The duration of the potential signal is set according to the relationship between the distance A and each preset distance:

[0073] When A < B1, the first preset potential signal duration C1 is selected as the potential signal duration;

[0074] When B1≤A<B2, the second preset potential signal duration C2 is selected as the potential signal duration;

[0075] When B2≤A<B3, the third preset potential signal duration C3 is selected as the potential signal duration;

[0076] When B3≤A<B4, the fourth preset potential signal duration C4 is selected as the potential signal duration.

[0077] In this embodiment, the duration of the potential signal is set according to the relationship between distance A and each preset distance. It can be understood that the duration of the potential signal refers to the reference time required for the first infrared light sensing device and the second infrared light sensing device to overlap and for the potential signal to be zero. When B4≤A, it is necessary for the staff to check the reversing baffle to determine whether the reversing baffle has malfunctioned. By setting the duration of the potential signal, reliable data support can be provided for determining whether the reversing baffle has been completely switched to the target powder hopper.

[0078] S110: Determine whether the reversing baffle has completely switched to the target powder hopper based on the potential signal, and issue an alarm reminder in real time when the reversing baffle has not completely switched to the target powder hopper, so as to control the reversing baffle.

[0079] In some embodiments of this application, determining whether the reversing baffle has completely switched to the target powder hopper based on the potential signal includes:

[0080] The time point f at which the potential signal changes to zero is collected;

[0081] The lower limit duration g of the potential signal is obtained, and based on the lower limit duration g, the duration Ci of the potential signal, and the time node f, it is determined whether the reversing baffle has completely switched to the target powder hopper, where i = 1, 2, 3, 4, 5.

[0082] If f < g, then it is determined that the reversing baffle has not been completely switched to the target powder bin;

[0083] If g≤f<C i, then it is determined that the reversing baffle has completely switched to the target powder hopper;

[0084] If C<i<f, then it is determined that the reversing baffle has not been completely switched to the target powder bin.

[0085] In this embodiment, the time node f when the potential signal changes to zero is collected, which is the time required from the initial state to the potential signal becoming zero, such as 60 seconds. The duration Ci of the potential signal is a reference time, that is, a standard time, such as 75 seconds. Since there will be fluctuations in actual operation, the lower limit time g of the potential signal duration is also obtained, that is, the minimum time for the potential signal to become zero, such as 45 seconds. At this time, it can be determined that the reversing baffle has completely switched to the target powder bin. When f < g or Ci < f, it indicates that the reversing baffle has not completely switched to the target powder bin. This invention can monitor the position of the coal powder bin reversing baffle to ensure that the reversing baffle is accurately switched to the target powder bin and prevent powder leakage from the powder bin.

[0086] Embodiments of the present invention also disclose a computer device, the computer device including a processor, a memory, and a photovoltaic module temperature monitoring and management program stored in the memory and executable by the processor, wherein when the photovoltaic module temperature monitoring and management program is executed by the processor, it implements the steps of the photovoltaic module temperature monitoring method described above.

[0087] Embodiments of the present invention also disclose a computer-readable storage medium storing a photovoltaic module temperature monitoring and management program, wherein when the photovoltaic module temperature monitoring and management program is executed by a processor, it implements the steps of the photovoltaic module temperature monitoring method described above.
