[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a first embodiment of the present invention provides a sensor communication method. As shown in fig. 1, the sensor communication method includes, for example, steps S11 to S15.
Step S11: receiving a sensor communication instruction;
step S12: reading a target sensor protocol from a configurable file according to the sensor communication instruction, wherein the configurable file comprises a plurality of sensor protocols corresponding to a plurality of sensors;
step S13: sending the write sensor data in the target sensor protocol to a target sensor so that the target sensor replies initial sensor data according to the write sensor data;
step S14: analyzing the initial sensor data according to the target sensor protocol to obtain target sensor data;
step S15: outputting the target sensor data.
The sensor communication command mentioned in step S11 includes, for example, a sensor manufacturer code and a sensor function type corresponding to a sensor manufacturer, and further includes a sensor serial number, i.e., a sensor ID. The types of sensor functions mentioned include, for example: CO22PM2.5, PM10, barometric pressure, air humidity, air temperature, noise, wind speed, wind direction, and brightness. Wherein each function type corresponds to a different serial number, for example, 1 represents CO2And 2 representsPM2.5, PM 3 represents PM10, PM 4 represents air pressure, PM 5 represents air humidity, PM 6 represents air temperature, PM 7 represents noise, PM 8 represents wind speed, PM 9 represents wind direction, and PM10 represents brightness, but the embodiment is not limited thereto. The sensor communication instruction is from a host computer, for example, and the host computer refers to a computer that can directly issue the operation instruction, such as a personal computer, a handheld device or a portable device, a tablet device, a multiprocessor system, a microprocessor-based system, an editable consumer electronics device, a network PC, a minicomputer, a mainframe computer, a distributed computing environment including any of the above systems or devices, and the like. Further, step S11 includes, for example: analyzing the sensor communication instruction to obtain a sensor manufacturer code and a sensor function type; and reading the target sensor protocol from the configurable file according to the sensor manufacturer code number and the sensor function type.
In step S12, the configurable file may be stored in a designated location of the host computer, in a designated location local to the sending card, or in another location that the sending card can read. Wherein, the sending card is an LED display screen controller with a receiving card (scanning card) in the LED display screen control system. The configurable file provided by the embodiment integrates multiple sensor protocols, and a new sensor protocol is encapsulated on the basis of the process of accessing the sensor to acquire data by using the protocol character string in the prior art, so that the configurable file is compatible with a plurality of sensors meeting a certain technical standard. Briefly, the mentioned configurable file comprises a plurality of sensor protocols corresponding to a plurality of sensors. The sensor protocols corresponding to the same sensor by different manufacturers may be different, the sensor protocols corresponding to different sensors are different, the sensor protocols corresponding to different functions of the same sensor may also be different, the protocols are integrated into the configurable file, and the configurable file can be changed manually and flexibly, so that the operation is very convenient. The mentioned sensor protocol includes, for example, a serial port address, a sensor serial number, a sensor function type, a sensor manufacturer, a sensor product model, a sensor type, a function type corresponding to a sensor communication instruction, a baud rate, whether an integrated sensor protocol is supported, a common sensor protocol array, and an integrated sensor protocol array.
Specifically, the mentioned serial port address is a communication address for data interaction between the protocol and the sensor through the serial port. The mentioned serial number of the sensor is, for example, a serial number corresponding to the sensor in the upper computer, that is, the corresponding sensor can be found in the upper computer through the serial number. The types of sensor functions mentioned are as described above, and include, for example: one or more of CO2, PM2.5, PM10, barometric pressure, air humidity, air temperature, noise, wind speed, wind direction, and brightness. The mentioned sensor manufacturers are providers of the sensors, and the sensor protocols are different for different manufacturers. The mentioned sensor product model is the model of the sensor product corresponding to the sensor manufacturer. The mentioned sensor types comprise, for example, integrated sensors. The mentioned sensor communication instructions correspond to function types including, for example: modifying sensor addresses, reading sensor numbers, or modifying baud rates, etc. The mentioned baud rate refers to the sensor data transmission efficiency. The mentioned whether the integrated (multifunctional integrated) sensor protocol is supported or not can be understood that some sensors support multiple functions, such as the acquisition of temperature and humidity data, a user can send a protocol directly accessing the temperature or the humidity to respectively obtain the temperature data or the humidity data, or only send an integrated protocol to simultaneously obtain the temperature data and the humidity data, and whether the integrated (multifunctional integrated) sensor protocol is supported or not to represent whether a target sensor supports the sending of the special protocol or not. The mentioned generic sensor protocol array comprises, for example, a plurality of generic sensor protocols, one protocol corresponding to a function of sensor data. The mentioned integrated sensor protocol array is used to store the integrated (integrated) sensor protocol, i.e. to acquire data of all functions of the target sensor by one protocol.
It should be noted that the mentioned serial port address is located at the outermost layer of the configurable file, for example, the mentioned other parameters are located at the non-outer layer, that is, the outermost layer of the configurable file includes the serial port address and a protocol array set, the protocol array set includes a plurality of protocol arrays, each protocol array includes the aforementioned other parameters, and the contents of the protocol arrays can be manually added by a user according to an agreed protocol rule, where it is not necessary to link a sensor protocol with a sensor, and it is only necessary to ensure that the sensor protocol corresponding to the sensor exists in the configurable file.
In step S13, the written sensor data is located in, for example, a generic sensor protocol array or an integrated sensor protocol array of the target sensor protocol. The write sensor data includes, for example, a sensor device address, a function code, a register start address, a register length, and a check bit. The initial sensor data mentioned includes, for example, a sensor device address, a function code, a valid data byte, a return data field, and a check bit.
Further, the sending of the write sensor data in the target sensor protocol to the target sensor mentioned in step S13 includes, for example: acquiring a target serial port address and a target baud rate from the target sensor protocol; and sending the write sensor data to the target sensor based on the target serial port address and the target baud rate. The serial port communicating with the target sensor is found through the target serial port address, so that the required data transmission rate is selected based on the target baud rate, the data of the write sensor is sent out, and therefore the data of the write sensor can completely and accurately reach the target sensor.
In step S14, the target sensor data is, for example, data that can be output for display.
Further, step S14 includes, for example: judging whether the initial sensor data is complete according to the data length value in the target sensor protocol; and responding to the completeness of the initial sensor data, and analyzing the initial sensor data according to the target sensor protocol to obtain target sensor data. The data length values mentioned are, for example, in the generic sensor protocol array or in the integrated sensor protocol array. The data length value represents the data length of returning a packet of sensor data, namely the number of bytes included in the packet of sensor data, and whether the initial sensor data is complete is judged through the data length value, so that the complete initial sensor data can be received, and the condition that the received data is wrong is avoided.
Further, step S14 includes, for example: judging whether the data head in the initial sensor data is the same as the data head in the writing sensor data; responding to the fact that a data head in the initial sensor data is the same as a data head in the write sensor data, and verifying the initial sensor data according to a data verification mode in the target sensor protocol to obtain a verification result; judging whether a check code in the initial sensor data is the same as the check result; and combining the initial sensor data according to a data analysis rule in the target sensor protocol to obtain the target sensor data in response to the fact that the check code is the same as the check result. The data header mentioned here is, for example, the first two bytes of data, because the initial sensor data is generated based on the write sensor data, and therefore, the data headers of the initial sensor data and the write sensor data should be the same, if not the same, indicating that the data is erroneous. The last two bytes of the initial sensor data are, for example, check codes, which are calculated based on the preceding bytes. The mentioned data checking method is for example in a common sensor protocol array or an integrated sensor protocol array. If the data is correct, the verification result obtained by verifying the initial sensor data based on the data verification mode should be the same as the verification code, and the data subjected to verification is other byte data in the initial sensor data excluding the verification code. The safety and reliability of the sensor data can be ensured through the judgment of the data head and the check code. The mentioned data parsing rules are for example in a common sensor protocol array, or an all-in-one sensor protocol array, including for example: the function code corresponding to each function, the reading position of the effective data area of the function, the length to be read of the effective data area, the unit measuring range and the high-low combination mode of the data reported by the sensor. The function code corresponding to each mentioned function includes, for example: 1: CO2, 2: PM2.5, 3: PM10, 4: air pressure, 5: gas-wet, 6: air temperature, 7: noise, 8: wind speed, 9: wind direction and 10: brightness. The mentioned combination modes of high and low bits of data reported by the sensor include, for example: 0: big end and 1: a small end. The mentioned data check method includes, for example, CRC check, sum check, odd check, and the like. In addition, the data combining method includes a summation combination in addition to the above-mentioned high and low bit combinations.
In step S15, the output target sensor data is output to, for example, a host computer and displayed.
Further, step S15 includes, for example: and processing the target sensor data according to the unit measuring range in the target sensor protocol and then outputting the processed target sensor data. Specifically, the output data is, for example, the target sensor data multiplied by the unit range, for example, the unit range is, for example, 0.1, the output data needs to be obtained by multiplying the target sensor data by 0.1, and in some cases, the user wants to output the sensor data with the unit range, so that the user's requirements in different scenarios can be met.
Further, before step S13, for example, the method further includes: and caching the target sensor protocol in a queue. Specifically, a plurality of sensor protocols corresponding to a plurality of sensor communication instructions are queued, so that when a plurality of sensors access the sensors through a serial port, data can be read and written in order, and confusion of the data during sending or returning can be avoided. This avoids the confusion of sending read sensor data.
To facilitate understanding of the present embodiment, a specific implementation of the present embodiment is described below with reference to fig. 2. The sensor communication method provided by the present embodiment is implemented in the system shown in fig. 2, for example.
As shown in fig. 2, the system includes a host computer/player, a transmitter card, and various sensors. The transmitting card internally comprises a sensor function data provider, a configurable file resolver, a queue worker, a sensor data transceiver, a sensor return data resolver, a serial port interactor, a data checker and a data combiner. The operating system inside the transmitting card is, for example, a Linux system. The transmitting card is connected with various sensors through a serial port, a serial docking station or a serial hub, and the sensors comprise: temperature sensor, humidity sensor, CO2Sensors and integrated multifunction sensors.
In the following, an example will be described in which a sensor communication command is transmitted to read temperature data of a temperature sensor.
The upper computer sends a sensor communication instruction to the sending card, wherein the sensor communication instruction comprises, for example, the serial number of the temperature sensor on the upper computer, the functional type of the temperature sensor and the manufacturer of the temperature sensor. And the sensor function data provider of the sending card sends the command to the configurable file parser after receiving the command, the configurable file parser acquires a corresponding target sensor protocol according to the command and sends the target sensor protocol to the sensor function data provider, and the sensor function data provider sends the target sensor protocol to the queue work device.
The queue worker receives the target sensor protocol, then saves the protocol through the queue, and sends the protocol to the sensor data transceiver. The sensor data transceiver respectively forwards the protocol to the sensor return data parser and the serial port interactor.
The serial port interactor receives the target sensor protocol and then resolves the serial port address and the baud rate in the acquired protocol to open a corresponding serial port, namely the serial port reading and writing sensor can be used, the serial port interactor writes writing sensor data in the target sensor protocol into the temperature sensor through the serial port, and the temperature sensor returns initial temperature data to the serial port interactor according to the writing sensor data. The serial port interactor sends the initial temperature data to the sensor data transceiver, so that the sensor data transceiver reads the corresponding byte number according to the data length value in the target sensor protocol to ensure the integrity of the initial temperature data, and then sends the initial temperature data to the sensor return data analyzer.
The sensor return data analyzer firstly performs data head matching, namely matching a data head of initial temperature data with a data head of sensor data written in a protocol, and after the matching is successful, sending a target sensor protocol and the initial temperature data to the data checker. The data calibrator verifies the initial temperature data according to the data verification type in the target sensor protocol to obtain a verification result and replies the verification result to the sensor return data analyzer, the sensor return data analyzer judges that the verification result is the same as the verification code, the data analysis rule and the data in the target sensor protocol are transmitted into the data combiner, the data combiner recombines the return data to obtain effective data and replies the effective data to the sensor return data analyzer, the sensor return data analyzer transmits the effective data to the sensor function data provider, the sensor function data provider is provided with an interface for acquiring the sensor data and can output the effective data to an upper computer or a player for display, wherein the output effective data can be data with unit measuring range or data without unit measuring range.
In summary, the configurable file in the sensor communication method disclosed in the first embodiment of the present invention includes multiple sensor protocols corresponding to multiple sensors, and the target sensor protocol is read from the configurable file through the sensor communication instruction, so that the sensor communication method can be compatible with the sensor protocols of different manufacturers and can adapt to various types of sensors only through one set of code logic, thereby reducing the development difficulty of multi-sensor application and greatly improving the performance of an upper computer; the writing sensor data in the target sensor protocol is sent to the target sensor, so that the target sensor replies the initial sensor data, and the initial sensor data is analyzed according to the target sensor protocol to obtain the target sensor data and then output the target sensor data, thereby simplifying the sensor data analysis method, ensuring that the process is clear and easy to understand, and improving the development efficiency; the target sensor protocol is stored through the queue, and confusion in sending and reading sensor data is avoided; the data of the target sensor is processed and then displayed in a unit measuring range, so that the requirements of users in different scenes can be met; the safety and reliability of the sensor data are guaranteed through operations such as data head judgment, data verification and the like.
