Description

Technical Field

[0001] The present application relates to the field of photovoltaic information technology, and in particular to a method, system and medium for processing cell traceability signals for a photovoltaic production line. Background Art

[0002] With the development of automation equipment, the production of photovoltaic cells has also entered the automation process. However, in the existing automated production process of cells, each cell and the host computer usually need to perform multiple handshake interactions to synchronize the production data between the two. For example, when the cell enters the photovoltaic production line, the host computer needs to read the write permission request of the cell before it can write the wafer code of the cell into the corresponding cell. However, this write operation often fails due to uncontrollable external factors. After the host computer receives the write failure signal, it needs to re-read the write permission request of the cell and perform the wafer code write operation again. It can be seen that if any process of the handshake interaction between the two parties fails, it will increase the complexity of the automated production process and reduce reliability and efficiency. Summary of the invention

[0048] The cell traceability signal processing method for a photovoltaic production line provided in the embodiment of the present application can be applied to Figure 1 The cell traceability signal processing system for a photovoltaic production line is shown. The system includes a plurality of cells, at least one carrier 10, a conveying mechanism 20, a first photoelectric sensor 30, a second photoelectric sensor 31 and a host computer 40. The host computer is in communication connection with the carrier 10, the conveying mechanism 20, the first photoelectric sensor 30 and the second photoelectric sensor 31. The cell is mounted on the carrier 10, and the carrier 10 is placed on the conveying mechanism 20 of the photovoltaic production line. The first photoelectric sensor 30 is provided at the entrance of the photovoltaic production line, and the second photoelectric sensor 31 is provided at the exit.

[0049] In one embodiment, the host computer 40 is used to collect the first photoelectric sensing signal triggered by the first photoelectric sensor 30 when the carrier 10 enters the photovoltaic production line; analyze the first photoelectric sensing signal to obtain the identity information of each battery cell on the carrier, and synchronize the data of each battery cell according to the identity information.

[0050] In one of the embodiments, the host computer 40 is also used to parse the first photoelectric sensing signal to obtain the unique code of the carrier; the carrier generates a corresponding internal virtual code for each of the battery cells; based on the unique code of the carrier, the wafer code group corresponding to each battery cell on the carrier is queried from the historical database; each of the internal virtual codes is read and bound to the wafer code group to complete the data synchronization of each of the battery cells.

[0051] In one embodiment, the host computer 40 is also used to collect the second photoelectric sensing signal triggered by the second photoelectric sensor 31; analyze the second photoelectric sensing signal to obtain the unique code of the carrier 10; match the second photoelectric sensing signal with the corresponding first photoelectric sensing signal according to the unique code of the carrier 10 to determine that the carrier 10 outputs the photovoltaic production line.

[0052] In one of the embodiments, the host computer 40 is also used to collect the real-time start / stop signals and servo position signals of the transmission mechanism 20; analyze the start / stop signals to determine the operating status of the transmission mechanism 20; if the analysis result of the current start / stop signals is a stop status, analyze the current servo position signal to determine the servo position of the transmission mechanism 20; compare the servo position with the preset loading and unloading position to determine the loading and unloading status of the carrier.

[0053] In one embodiment, the host computer 40 is also used to obtain the first servo position of the transmission mechanism 20 at the current moment and the second servo position at the previous moment; determine the movement distance of the transmission mechanism 20 according to the first servo position and the second servo position; compare the movement distance with the preset distance, if the movement distance is less than or equal to the preset distance, it is determined that the start-stop signal is not synchronized with the servo position signal, otherwise, they are synchronized.

[0054] In one of the embodiments, the host computer 40 is also used to analyze the start-stop signal of the transmission mechanism 20 at the current moment after the start-stop signal is out of synchronization with the servo position signal; based on the analysis result of the start-stop signal at the current moment, a servo correction signal is generated to act on the start-stop signal to adjust the operating state of the transmission mechanism 20.

[0055] In one embodiment, the conveying mechanism 20 includes at least one belt connection inflection point formed by a front conveying belt and a rear receiving belt.

[0056] The host computer 40 is also used to collect the front start-stop signal on the front conveyor belt and the rear start-stop signal on the rear receiving belt; analyze the front start-stop signal to determine the operating state of the front conveyor belt; if the front conveyor belt is in a moving state when the carrier runs to the belt turning point, a front adjustment signal is generated to adjust the front start-stop signal to a stopped state, and a rear adjustment signal is generated to adjust the rear start-stop signal to a moving state.

[0057] In an exemplary embodiment, Figure 2 As shown, a cell traceability signal processing method for a photovoltaic production line is provided. The method is applied to Figure 1 The host computer in is used as an example to illustrate, including the following steps 201 to 202.

[0058] Step 201 , collecting a first photoelectric sensing signal triggered by the first photoelectric sensor when the carrier enters a photovoltaic production line.

[0059] Step 202: parse the first photoelectric sensing signal to obtain the identity information of each battery cell on the carrier, and synchronize the data of each battery cell according to the identity information.

[0060] The identity information of each battery cell includes an internal virtual code automatically generated by the carrier for each battery cell.

[0061] Specifically, on existing photovoltaic production lines, the host computer needs to read the unique code of the carrier and write the wafer code of the cell into each cell. The reading and writing process is cumbersome and the writing of the wafer code is easily affected by external factors and fails. In this application, the host computer only needs to read the identity information of the cell on the carrier to achieve data synchronization between the host computer and the cell, which greatly reduces the complexity of system operation, reduces the number of request response interactions between the host computer and the cell, and improves the stability and response speed of the overall system.

[0062] In one embodiment, if Figure 3 As shown, step 202 analyzes the first photoelectric sensing signal, obtains the identity information of each battery cell on the carrier, and synchronizes the data of each battery cell according to the identity information, specifically including the following steps 301 to 303.

[0063] Step 301, analyzing the first photoelectric sensing signal to obtain a unique code of the carrier; the carrier generates a corresponding internal virtual code for each of the battery cells.

[0064] Specifically, the first photoelectric sensing signal is parsed to obtain the unique code of the carrier and the internal virtual code automatically generated by the carrier for each battery cell.

[0065] Step 302: According to the unique code of the carrier, the wafer code group corresponding to each battery cell on the carrier is obtained from the historical database.

[0066] Specifically, since the wafer codes of the cells on the carrier are fixed, the wafer code groups corresponding to the cells on the carrier are queried from the historical database according to the unique code of the carrier.

[0067] Step 303, reading each of the internal virtual codes and binding them with the wafer coding group to complete data synchronization of each of the battery cells.

[0068] Specifically, after obtaining the wafer code group of each battery cell, the host computer reads the internal virtual code of each battery cell and binds it with the wafer code group, thereby realizing data synchronization between the host computer and the battery cell.

[0069] In this embodiment, an internal virtual code is assigned to the battery cell, and the host computer obtains the internal virtual code by reading and binds it to the wafer coding group, thereby achieving one-way data synchronization between the host computer and the battery cell, avoiding the write failure problem caused by the host computer writing the wafer coding for the battery cell in the prior art, reducing the complexity of system interaction, and improving system stability.

[0070] In an exemplary embodiment, Figure 4 As shown, after step 202 parses the first photoelectric sensing signal to obtain the identity information of each battery cell on the carrier and synchronizes the data of each battery cell according to the identity information, the method further includes the following steps 203 to 205.

[0071] Step 203: collecting a second photoelectric sensing signal triggered by the second photoelectric sensor.

[0072] Step 204: parse the second photoelectric sensing signal to obtain the unique code of the vehicle.

[0073] Step 205, matching the second photoelectric sensing signal with the corresponding first photoelectric sensing signal according to the unique code of the carrier, and determining that the carrier outputs the photovoltaic production line.

[0074] Specifically, when the cells on the carrier complete all processing processes and output the photovoltaic production line, the second photoelectric sensor detects the second photoelectric sensing signal triggered when the carrier leaves. The second photoelectric sensing signal is parsed to obtain the unique code of the carrier, and the first photoelectric sensing signal corresponding to the second photoelectric sensing signal is matched according to the unique code to determine that the carrier outputs the photovoltaic production line.

[0075] More specifically, after parsing the second photoelectric sensing signal, the wafer code bound to each battery cell is also obtained, thereby ensuring that the source of each battery cell can be accurately traced at any time.

[0076] Optionally, the processing time of each battery cell on the carrier may also be determined according to the first photoelectric sensing signal and the second photoelectric sensing signal.

[0077] In this embodiment, the photovoltaic production line output by the carrier is determined by acquiring the second photoelectric sensing signal at the output of the carrier, and the wafer code bound to each cell is acquired through the second photoelectric sensing signal, thereby ensuring that the source of each cell can be accurately traced at any time, thereby realizing the traceability of the cell.

[0078] In an exemplary embodiment, Figure 5 As shown, the host computer processes the first photoelectric sensing signal and the second photoelectric sensing signal as well as the start / stop signal and the servo position signal of the transmission mechanism. The method further includes the following steps 401 to 404.

[0079] Step 401, collecting the real-time start / stop signal and servo position signal of the transmission mechanism.

[0080] Wherein, the start-stop signal indicates the running state of the transmission mechanism, including the stop state and the moving state. The servo position signal indicates the servo position of the transmission mechanism. The start-stop signal and the servo position signal are synchronous signals.

[0081] Step 402: parse the start / stop signal to determine the operating status of the transmission mechanism.

[0082] Step 403: If the analysis result of the current start-stop signal is a stop state, the current servo position signal is analyzed to determine the servo position of the transmission mechanism.

[0083] Step 404 , comparing the servo position with a preset loading and unloading position to determine the loading and unloading state of the carrier.

[0084] The preset loading and unloading positions include a loading position and an unloading position.

[0085] Specifically, the start / stop signal and servo position signal of the conveying mechanism are collected in real time. The start / stop signal is analyzed to determine the operating state of the conveying mechanism. If the conveying mechanism is in a stopped state, the current servo position signal is analyzed to determine the servo position of the conveying structure. The servo position is compared with the loading position and the unloading position to determine whether the battery cell on the carrier needs to be loaded or unloaded or continue to move forward.

[0086] In this embodiment, by analyzing the start / stop signals and servo position signals of the conveying mechanism, the system has a clear response mechanism for each loading or unloading event of the battery cell, thereby ensuring the accuracy and traceability of the data.

[0087] In one embodiment, the start / stop signal and servo position signal of the transmission mechanism are synchronous signals. However, since the start / stop signal and servo position signal of different processing stages are constantly changing, the two signals are prone to being out of sync. Therefore, it is necessary to monitor the synchronization of the two signals in real time. Figure 6 As shown, the method further includes the following steps 501 to 503.

[0088] Step 501, obtaining a first servo position of the transmission mechanism at a current moment and a second servo position at a previous moment.

[0089] Step 502: Determine the movement distance of the transmission mechanism according to the first servo position and the second servo position.

[0090] Step 503, comparing the movement distance with a preset distance, if the movement distance is less than or equal to the preset distance and the start-stop signal is in a moving state, determining that the start-stop signal is not synchronized with the servo position signal, otherwise, they are synchronized.

[0091] Specifically, when the start-stop signal is in a moving state, the first servo position of the transmission mechanism at the current moment and the second servo position at the previous moment are collected, and the distance between the two is subtracted to obtain the movement distance of the transmission mechanism; the movement distance is compared with the preset distance, and if the movement distance is less than or equal to the preset distance, it is determined that the start-stop signal is not synchronized with the servo position signal, otherwise, they are synchronized.

[0092] In one embodiment, after determining that the start / stop signal is not synchronized with the servo position signal, the method further includes the following:

[0093] The start / stop signal of the transmission mechanism at the current moment is analyzed. According to the analysis result of the start / stop signal at the current moment, a servo correction signal is generated to act on the start / stop signal to adjust the analysis result of the start / stop signal.

[0094] Wherein, the servo correction signal includes a motion correction signal and a stop correction signal.

[0095] In detail, the start-stop signal of the transmission mechanism at the current moment is analyzed. When the start-stop signal is in a moving state, if the movement distance of the servo position corresponding to the servo position signal at the previous and next moments is less than or equal to the preset distance, it means that the transmission mechanism is currently in a stopped state, and the upper computer generates a stop correction signal to act on the start-stop signal, and corrects the start-stop signal from a moving state to a stopped state.

[0096] Optionally, if the start-stop signal shows a stop state, and the servo position corresponding to the servo position signal is still changing, it means that the transmission mechanism is currently in a moving state, and the upper computer generates a motion correction signal to act on the start-stop signal, correcting the start-stop signal from a stop state to a moving state.

[0097] In this embodiment, by correcting the asynchronous start / stop signals and servo position signals, the accuracy and synchronization of the data recorded by the loading and unloading events are ensured, thereby improving the processing accuracy of the battery cells.

[0098] In an exemplary embodiment, the conveying mechanism includes at least one belt connection inflection point formed by a front conveying belt and a rear receiving belt, and the front conveying belt and the rear receiving belt have corresponding front start-stop signals and rear start-stop signals, respectively. In order to achieve normal forward movement of the carrier at the inflection point, Figure 7 As shown, the method also includes the following steps 601 to 603.

[0099] Step 601, collecting the front start-stop signal on the front conveying belt and the rear start-stop signal on the rear receiving belt.

[0100] Step 602: Analyze the front start / stop signal to determine the running state of the front conveyor belt.

[0101] Step 603, if the front conveyor belt is in motion when the carrier runs to the belt connection inflection point, a front adjustment signal is generated to adjust the front start-stop signal to a stop state, and a rear adjustment signal is generated to adjust the rear start-stop signal to a motion state.

[0102] Specifically, the front start-stop signal on the front conveyor belt and the rear start-stop signal on the rear receiving belt are collected. When the carrier has not reached the connecting inflection point, the front start-stop signal shows that the conveyor belt is in motion, and the rear start-stop signal shows that the rear receiving belt is in a stopped state. If the front conveyor belt is still in motion when the carrier runs to the inflection point of the belt, the upper computer generates a front adjustment signal to act on the front start-stop signal to adjust the front conveyor belt to a stopped state, and generates a rear adjustment signal to act on the rear start-stop signal to adjust the rear receiving belt to a moving state, which solves the problem that when the rear receiving belt receives the carrier, if the front conveyor belt continues to move, the positioning of the carrier on the rear conveying device will be offset, thereby ensuring the precise positioning of the carrier during the transportation process.

[0103] In a preferred embodiment, a cell traceability signal processing method for a photovoltaic production line is provided, which is applied to Figure 1 The cell traceability signal processing system for a photovoltaic production line specifically includes the following contents:

[0104] S1, collecting a first photoelectric sensing signal triggered by a first photoelectric sensor when the carrier enters a photovoltaic production line, parsing the first photoelectric sensing signal, and obtaining the unique code UID of the carrier and the internal virtual code VID of each solar cell.

[0105] S2, according to the unique code of the carrier, query the wafer code WaferID corresponding to each battery cell on the carrier from the historical database, and bind it with the internal virtual code VID of each battery cell to complete the data synchronization of each battery cell.

[0106] S3, collecting the real-time start / stop signal E001_X and servo position signal E001_P of the transmission mechanism.

[0107] S4, analyze the start-stop signal E001_X. If E001_X=1, it means that the transmission mechanism is in a stopped state, then analyze the current servo position signal E001_P to determine the servo position of the transmission structure. Among them, the distance interval of the loading position is [1062,1072], and the distance interval of the unloading position is [285,295]. When the servo position E001_P=1064, the battery cell on the carrier is loaded; when the servo position E001_P=290, the battery cell on the carrier is unloaded. If E001_X=0, it means that the transmission mechanism is in a moving state, and the current servo position signal E001_P changes accordingly.

[0108] S5, when the start-stop signal E001_X=0 motion state, collect the first servo position E001_P=m at the current moment and the second servo position E001_P=n at the previous moment, and make a difference between the distances between the two to obtain the motion distance (mn) of the transmission mechanism. If the motion distance (mn) is ≤0.8, it is determined that the start-stop signal E001_X is not synchronized with the servo position signal E001_P. At this time, the start-stop signal shows E001_X=0, and the upper computer generates a motion correction signal to act on the start-stop signal E001_X, and corrects the start-stop signal to the stop state E001_X=1.

[0109] S6, if the start-stop signal shows E001_X=1, it should be in the stopped state, and the servo position corresponding to the servo position signal is still changing, which means that the transmission mechanism is currently in the moving state. The upper computer generates a motion correction signal to act on the start-stop signal E001_X, and corrects the start-stop signal E001_X=1 to the moving state E001_X=0.

[0110] S7, when the carrier runs to the turning point of the transmission mechanism, the upper computer generates a front adjustment signal to act on the front start-stop signal, adjusts the front conveyor belt to a stopped state, and generates a rear adjustment signal to act on the rear start-stop signal, adjusts the rear receiving belt to a moving state.
