[0007] Optionally, the target message address includes at least one; The step of establishing a one-to-one correspondence between the target message address and the original parameter information, the preset parameter scaling conditions, and the preset data filling conditions, based on the target message requirements, to form the mapping relationship library, includes: Establish the index relationship between at least one of the target message addresses and at least one of the original parameter information, the preset parameter scaling conditions, and the preset data filling conditions.

[0008] Optionally, the step of generating message transmission data from the original parameter information and filling in the data according to the preset parameter scaling conditions and preset data filling conditions in the target message requirement includes: According to the preset parameter calibration conditions, the original parameter information is converted into the message transmission data; The starting padding bit of the message transmission data is determined according to the third calibration parameter and the preset data padding condition; and the starting padding bit is filled sequentially according to the data length of the message transmission data; wherein the third calibration parameter and the preset data padding condition have a matching relationship.

Alternatively, the starting padding bits may be filled sequentially according to the Motorola data format, based on the data length of the data sent in the message.

[0011] Optionally, the message generation method for the liquid heater further includes: Obtain a preset scheduling strategy; wherein the preset scheduling strategy includes a time-based scheduling strategy or an event-based scheduling strategy; When the preset scheduling strategy is met, the liquid heater is controlled to send a message to an external device.

[0012] According to another aspect of the present invention, a liquid heater is provided, comprising: a control module and a communication module; the communication module is communicatively connected to the control module; The control module is used to execute the message generation method for the liquid heater as described in any embodiment of the first aspect, and to send messages through the communication module.

For target customers from different OEMs with significantly different CAN communication protocols, the corresponding target message requirements can be directly called through the target message address during the adaptation process, which can effectively shorten the adaptation cycle of liquid heaters to different target customers. According to the preset parameter calibration conditions in the called target message requirements, message transmission data adapted to the CAN communication protocol of the target customer is generated based on the original parameter information, so as to enable communication transmission between the liquid heater and external devices.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] As described in the background section, traditional CAN communication for high-pressure liquid heaters has the following drawbacks: First, because the message address and content sent by the controller of the high-pressure liquid heater are fixed, if the CAN message matrices required by different customers are different, the firmware inside the heater controller needs to be modified, and software programs adapted to the new customer requirements need to be redeveloped to adapt to the communication protocols of different equipment manufacturers, which results in a long software development cycle. Second, the encoding of the parameter calibration method for CAN messages is integrated into the software program, making it impossible to quickly respond to the corresponding customized requirements of different customers for parameter calibration methods. Third, the message data filling logic is strongly coupled with the CAN message matrix of the adapted customer, which greatly increases the maintenance cost. Due to the above-mentioned drawbacks of CAN communication, existing high-pressure liquid heaters cannot flexibly configure and efficiently transmit message information according to the needs of different customers.

[0022] Based on the above-mentioned technical problems, the present invention proposes the following technical solution: This invention provides a method for generating messages for a liquid heater. Figure 1 This is a flowchart illustrating a message generation method for a liquid heater according to an embodiment of the present invention. This embodiment is applicable to situations where a high-pressure liquid heater can flexibly generate messages to meet the different message information requirements of various customers. The method can be executed by a control device within the high-pressure liquid heater, which can be implemented in hardware and / or software and is configured within the high-pressure liquid heater. Figure 1 As shown, the message generation method for this liquid heater specifically includes the following steps: S110. Obtain the target message requirements; the target message requirements include the target message address, original parameter information, preset parameter calibration conditions, and preset data filling conditions.

[0023] Specifically, since different customers may have different needs for message information, when configuring the liquid heater, it is necessary to first obtain the corresponding message requirements of different customers, i.e., target message requirements. Target message requirements can include multiple pieces of information. Among them, the target message address is the target message ID, which has a matching relationship with the corresponding target customer. That is, once the target customer is determined, the corresponding target message address can be determined, which can serve as an index for finding the corresponding message information of the target customer. The original parameter information consists of the relevant physical parameters of the liquid heater and the corresponding required values, such as water temperature and heating power. The preset parameter calibration conditions are the data conversion types required by the target customer, and the preset data filling conditions are the rules for the target customer to fill the data bits in the generated message data.

[0024] S120. Establish and store a mapping relationship library based on the target message requirements. Based on the target message address, call the corresponding target message requirements from the mapping relationship library. The mapping relationship library represents the index relationship of the target message address.

[0025] Specifically, based on the target customer's target message requirements, a mapping database of target message addresses and other relevant information is established using the target message address as an index, and stored in the control board of the liquid heater. This allows the target customer to access the corresponding target message requirements from the mapping database via the target message address during the use of the liquid heater, and apply them to the liquid heater for execution. This enables the liquid heater to be flexibly adapted to target customers from different OEMs with significantly different CAN communication protocols, allowing them to access the corresponding target message requirements via the target message address, effectively shortening the adaptation cycle for different target customers; for example, the adaptation cycle for a new target customer's CAN protocol can be shortened from two weeks to one day.

[0026] S130. Based on the preset parameter calibration conditions and preset data filling conditions in the target message request, generate message sending data from the original parameter information and fill in the data so that the liquid heater can send a message to the external device.

[0027] Specifically, based on the preset parameter calibration conditions in the target message requirements adapted to the target customer, message transmission data of the data type adapted to the CAN communication protocol of the target customer can be generated according to the original parameter information of the liquid heater, so that the liquid heater of the target customer can communicate and transmit with external devices. Compared with related technologies that integrate the relevant encoding of the CAN message parameter calibration conditions into the software program, the communication code of the liquid heater needs to be rewritten for target customers with different CAN protocol requirements, resulting in a long software development cycle before delivery. This embodiment of the invention establishes a one-to-one mapping relationship between the preset parameter calibration conditions and the target message address, which can quickly respond to the target customer's data type requirements according to the target message address. The generated message transmission data is filled into the corresponding data bits according to the preset data filling conditions called from the mapping relationship library, so that the data filling logic is decoupled from the CAN message matrix adapted to the target customer, which can effectively reduce the maintenance cost of the liquid heater. This allows the liquid heater to flexibly adapt to the communication protocol requirements of different target customers and generate corresponding message information, which greatly shortens the software development cycle of the liquid heater before delivery and enables the liquid heater to efficiently transmit message information to other external devices.

[0028] The message generation method for liquid heaters provided in this invention obtains the target message requirements of the target customer, uses the target message address in the target message requirements as an index, establishes a mapping relationship library between the target message address and other relevant information, and calls the corresponding target message requirements adapted to the target customer according to the target message address. For target customers from different OEMs with significantly different CAN communication protocols, the corresponding target message requirements can be directly called through the target message address during the adaptation process, which can effectively shorten the adaptation cycle of liquid heaters to different target customers. According to the preset parameter calibration conditions in the called target message requirements, message transmission data adapted to the CAN communication protocol of the target customer is generated based on the original parameter information, so as to enable communication transmission between the liquid heater and external devices. The message transmission data is filled into the corresponding data bits according to the preset data filling conditions, decoupling from the CAN message matrix of the target customer, effectively reducing the maintenance cost of the liquid heater. In this way, the liquid heater can flexibly adapt to the communication protocol requirements of different target customers, effectively shorten the development cycle of liquid heaters for manufacturers, and realize efficient transmission of message information between liquid heaters and external devices.

[0029] Based on the above embodiments, Figure 2 This is a schematic flowchart illustrating step S120 of a message generation method for a liquid heater according to an embodiment of the present invention. See also... Figure 2Optionally, step S120, which involves establishing and storing a mapping database based on the target message requirements, and retrieving the corresponding target message requirements from the mapping database based on the target message address, specifically includes the following steps: S121. Based on the target message requirements, establish a one-to-one index relationship between the target message address and the original parameter information, preset parameter calibration conditions, and preset data filling conditions to form a mapping relationship library.

[0030] Specifically, based on the target message requirements obtained from the target customer, and using the target message address as an index, an index relationship is established between each target message address corresponding to the target customer and the original parameter information, preset parameter calibration conditions, and preset data filling conditions, thus forming a mapping relationship library. The mapping relationship library for the liquid heater can include the target message requirements of at least one target customer. When multiple different target customers' target message requirements are included, relevant information can be accurately retrieved through the target message address. In other words, given the target customer's target message address, the original parameter information, preset parameter calibration conditions, and preset data filling conditions adapted to the target customer can be retrieved based on the target message address. Compared to the adaptation process in related technologies, which requires rewriting fixed communication code adapted to the corresponding target customer each time, this approach effectively shortens the software development cycle by establishing mapping relationships between data and flexibly invoking them.

[0031] S122. Based on the first calibration parameters and the mapping relationship library, write the target message address to call the original parameter information with index relationship, the preset parameter calibration conditions and the preset data filling conditions; wherein, the first calibration parameters and the target message address have a matching relationship.

[0032] Specifically, based on the established mapping relationship library and the first calibration parameters adapted to the data communication interface of the corresponding target customer, the target message address can be determined by the first calibration parameters. The target message address suitable for the target customer is dynamically written, and the originally written target message address is modified. In this way, the target message address can be modified by matching the first calibration parameters to modify the relevant variable parameters in the liquid heater, thereby realizing the flexible configuration of the CAN protocol related parameters of the liquid heater.

[0033] S123. Based on the second calibration parameter, establish a one-to-one correspondence between the original parameter information and the message storage address parameter, so as to read the original parameter information according to the message storage address parameter; wherein, the second calibration parameter and the message storage address parameter have a matching relationship.

[0034] Specifically, the message storage address parameter indicates the data location of the message data within the motherboard of the liquid heater. For example, for the same raw parameter information, such as water temperature, different target customers may require different storage addresses. For instance, customer A requires the water temperature data to be stored in data bits 01, while customer B requires it to be stored in data bits 100. When retrieving the corresponding raw parameter information based on the target message address, it is necessary to determine the specific data bits on the motherboard where the corresponding raw parameter information can be read, so that the corresponding raw parameter information can be accurately read and configured during liquid heater configuration. Therefore, a correspondence can be established between the various raw parameter information of the liquid heater required by the target customer and the dedicated message storage address parameter based on the second calibration parameter, so that accurate raw parameter information can be read based on the message storage address parameter. For example, the second calibration parameter can be set according to actual needs and is not limited here. The second calibration parameter contains matching information related to the corresponding message storage address.

[0035] Based on the above embodiments, the target message address includes at least one. For example, the target message address can be set to one, two, or more depending on the amount and length of data included in the target message requirements; no limitation is imposed here. Optionally, step S121, which establishes a one-to-one correspondence between the target message address and the original parameter information, preset parameter calibration conditions, and preset data filling conditions according to the target message requirements, forming a mapping relationship library, specifically includes the following steps: Establish an index relationship between at least one target message address and at least one of the following: original parameter information, preset parameter scaling conditions, and preset data filling conditions.

[0036] Specifically, based on the original parameter information, preset parameter calibration conditions, and preset data filling conditions, an index relationship can be established between data of appropriate length and the corresponding target packet address. The data indexed to different target packet addresses can be arbitrarily arranged and combined, without restriction. For example, assuming the target customer provides two target packet addresses, target address a and target address b, an index relationship can be established between the original parameter information and preset parameter calibration conditions and target address a, while the preset data filling conditions can be indexed between target address b.

[0037] Based on the above embodiments, Figure 3 This is a schematic flowchart illustrating step S130 of a message generation method for a liquid heater according to an embodiment of the present invention. See also... Figure 3 Optionally, step S130, which involves generating message transmission data from the original parameter information and filling in the data based on the preset parameter scaling conditions and preset data filling conditions in the target message requirement, specifically includes the following steps: S131. Based on the preset parameter calibration conditions, convert the original parameter information into message transmission data.

[0038] Specifically, based on the preset parameter calibration conditions required by the target customer, the original parameter information can be converted into message transmission data according to the specified data type. The data type can include integer, decimal, character, and Boolean types. For example, the preset parameter calibration conditions support linear or non-linear transformations of the original parameter information. Linear transformation is suitable for scenarios where the input original parameter information and the output message transmission data have a linear relationship; non-linear transformation is suitable for scenarios where the input original parameter information and the output message transmission data do not have a linear relationship. The appropriate data conversion method can be selected based on the data characteristics of the message transmission data required by the target customer, and no restrictions are imposed here.

[0039] S132. Determine the starting padding bit of the message transmission data according to the third calibration parameter and the preset data padding condition; and fill the data in sequence from the starting padding bit according to the data length of the message transmission data; wherein the third calibration parameter and the preset data padding condition have a matching relationship.

[0040] Specifically, based on the acquired preset data filling conditions and the third calibration parameter, the starting filling bit of the converted message transmission data can be determined during data filling, and data is sequentially filled into each data bit by the starting filling bit in a certain filling order. For example, in this embodiment of the invention, the third calibration parameter can support filling the message transmission data with any starting filling bit, and data of any length can be filled; and it also supports combining any starting filling bit with the data length.

[0041] Based on the above embodiments, optionally, step S132, which involves sequentially filling the data according to the data length of the message data, starting with the start padding bits, specifically includes the following steps: Depending on the length of the data to be sent in the message, the starting padding bits are filled sequentially according to the Intel data format; or, depending on the length of the data to be sent in the message, the starting padding bits are filled sequentially according to the Motorola data format.

[0042] Specifically, Intel data format and Motorola data format are two commonly used data formats in scenarios such as CAN messages. Intel data format corresponds to little-endian mode, meaning data is filled from the smallest start padding bit to the largest padding bit; Motorola data format corresponds to big-endian mode, meaning data is filled from the largest start padding bit to the smallest padding bit. For example, in the data filling process of this embodiment, it is supported to fill data sequentially from the smallest start padding bit to the largest padding bit, i.e., according to the Intel data format; it is also supported to fill data sequentially from the largest start padding bit to the smallest padding bit, i.e., according to the Motorola data format. No limitation is made here.

[0043] Based on the above embodiments, Figure 4 This is a schematic flowchart illustrating another message generation method for a liquid heater provided in an embodiment of the present invention. See also... Figure 4 Optional, S210. Obtain the target message requirements; the target message requirements include the target message address, original parameter information, preset parameter calibration conditions, and preset data filling conditions.

[0044] S220. Establish and store a mapping relationship library based on the target message requirements. Based on the target message address, call the corresponding target message requirements from the mapping relationship library. The mapping relationship library represents the index relationship of the target message address.

[0045] S230. Based on the preset parameter calibration conditions and preset data filling conditions in the target message request, generate message sending data from the original parameter information and fill in the data so that the liquid heater can send a message to the external device.

[0046] S240. Obtain the preset scheduling strategy; wherein, the preset scheduling strategy includes a time scheduling strategy or an event scheduling strategy.

[0047] Specifically, the preset scheduling strategy indicates the method of controlling the liquid heater to send messages. The time-based scheduling strategy involves sending messages to external devices periodically and cyclically according to the message sending time cycle required by the target customer; for example, the message sending cycle can be 1 second, but this is not limited. The event-based scheduling strategy indicates that the liquid heater is triggered to send a message when a certain condition is met during operation; for example, the event that triggers the liquid heater to send a message can be the vehicle air conditioning temperature falling below 24°C, but this is not limited.

[0048] It should be noted that one target customer can correspond to one scheduling strategy to trigger the liquid heater to send a message, meaning that only one of the time scheduling strategy and event scheduling strategy can be applied.

[0049] S250. When the preset scheduling strategy is met, control the liquid heater to send a message to the external device.

[0050] Specifically, based on the monitoring of time or related parameters by timers or corresponding sensors, when the time scheduling strategy or event scheduling strategy required by the target customer is met, the liquid heater is triggered to send a message to the external device.

[0051] This invention also provides a liquid heater. Figure 5 This is a schematic diagram of the internal structure of a liquid heater according to an embodiment of the present invention. See also...
