The communication module is widely applied to the fields of vehicle monitoring, access control systems, industrial data acquisition systems, digital audio and the like, has data communication capabilities such as Long Term Evolution (LTE), Wireless Fidelity (WIFI), and the like, and integrates rich functional interfaces such as Universal Asynchronous Receiver/Transmitter (UART) interfaces, Universal Serial Bus (USB) interfaces and the like. Before the communication module leaves the factory, pin detection related to the communication module is an important production link. The purpose of the pin detection is mainly to detect whether the function of the pin in the communication module is normal.

Pin detection generally detects pins exposed in the communication module, that is, pins available in the communication module for connection with other hardware. Before pin detection is performed, that is, before the method for pin detection provided by the embodiment of the present invention is performed, first, a physical connection between a detection device and the communication module is established, where the detection device is configured to detect a pin to be detected in the communication module, and the physical connection between the detection device and the communication module includes: and the pin in the detection equipment is correspondingly connected with the pin to be detected in the communication module. For example, when the pin to be detected in the communication module is a General-purpose input/output (GPIO) pin, the GPIO pin in the detection device is connected to the pin to be detected in the communication module to establish a physical connection between the detection device and the communication module; when the pin to be detected in the communication module is an ADC (Analog to Digital Converter) pin, the ADC pin in the detection device is connected to the ADC pin to be detected in the communication module, so as to establish a physical connection between the detection device and the communication module.

Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a pin detection method according to a first embodiment of the invention:

101. the detection device receives a detection request data packet. The detection request data packet is generated by a communication module according to functions of pins to be detected in the communication module and formats specified by a preset protocol, and the detection request data packet comprises function information of the pins to be detected and identity information of the pins to be detected.

102. The detection equipment determines the pin function to be detected according to the pin function information to be detected in the detection request data packet, determines the pin to be detected according to the identity information of the pin to be detected, and detects the corresponding pin function of the pin to be detected in the communication module to obtain a detection result.

The pin functions to be detected comprise GPIO functions and ADC functions; the detection result at least comprises that the corresponding pin function of the pin to be detected is in a normal state or an abnormal state.

In the method for pin detection provided in the embodiment of the present invention, the key to implement pin detection is that the detection device determines the function of the pin to be detected and the pin to be detected according to the detection request data packet generated and sent by the communication module, and then the detection device detects the corresponding pin function of the pin to be detected in the communication module to obtain the detection result. The communication module informs the detection device of the functions of the pins to be detected and the pins to be detected in the communication module in the format specified by the preset protocol, and the detection device completes corresponding detection.

Therefore, when the pins and functions to be detected are changed, the pins to be detected are increased or reduced, or the detected communication modules are different products, that is, the condition of the pins to be detected changes, the communication module only needs to include the pins to be detected to generate a new detection request data packet according to the changed functions of the pins to be detected and the pins to be detected, and send the new detection request data packet to the detection device, and the detection device completes corresponding detection according to the new detection request data packet and obtains a corresponding detection result. Therefore, in the pin detection method provided by the embodiment of the present invention, when the condition of the pin to be detected changes, it is not necessary for related technicians to rewrite a corresponding set of pin detection programs in the detection device to implement the detection of the pin in the communication module.

The detection device comprises a pin for connecting with the pin to be detected in the communication module and a communication pin for mutually transmitting data with the communication module, wherein the communication pin in the detection device is connected with a corresponding communication pin in the communication module, and the data mutually transmitted by the detection device and the communication module comprises the detection request data packet.

In some embodiments, the detection device comprises a single-chip microcomputer.

In some embodiments, the manner for the communication module to acquire the function of the pin to be detected and the information of the pin to be detected includes, but is not limited to: and reading a configuration file in the communication module, and receiving information about the functions of the pin to be detected, the pin to be detected and the like input by related technicians through an interpersonal interaction module in the communication module. The configuration file is a file which is edited in advance, has a specific format, and comprises information about the functions of the pin to be detected, the pin to be detected and the like.

When the condition of the pin to be detected changes, if the manner of acquiring the function of the pin to be detected and the information of the pin to be detected by the communication module is that the configuration file in the communication module is read, the pin detection can be completed only by modifying the part of the configuration file with a specific format, which is related to the information of the pin to be detected, by the related technical personnel and further executing the method for detecting the pin provided by the embodiment of the invention; if the communication module acquires the function of the pin to be detected and the information of the pin to be detected and the like in a manner that the interpersonal interaction module in the communication module receives the information about the function of the pin to be detected and the like input by related technicians, the pin detection can be completed only by modifying the information about the pin to be detected on the interpersonal interaction interface in the communication module by the related technicians and further executing the method for detecting the pin provided by the embodiment of the invention. Therefore, no matter what way the communication module obtains the functions of the pin to be detected and the information of the pin to be detected, when the condition of the pin to be detected changes, the way of completing the pin detection by modifying the information of the pin to be detected is more flexible, more efficient and more convenient than the way of completing the pin detection by re-writing a set of corresponding program for detecting the pin by related technicians.

Thus, in some embodiments, before step 101, the method of pin detection further comprises: the communication module obtains the functions of the pins to be detected and the pins to be detected by reading a configuration file in the communication module, wherein the configuration file is the pre-edited file with a specific format and comprises information about the functions of the pins to be detected, the pins to be detected and the like.

Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a pin detection method according to a second embodiment of the present invention:

201. the detection device receives a detection request data packet.

202. The detection equipment determines the functions of the pins to be detected according to the information of the functions of the pins to be detected in the detection request data packet, determines the pins to be detected according to the identity information of the pins to be detected, and detects the corresponding functions of the pins to be detected in the communication module to obtain a detection result.

203. And the detection equipment generates a detection response data packet in a format specified by the preset protocol according to the detection result and sends the detection response data packet to the communication module.

Steps

201 and 202 correspond to

steps

101 and 102 in fig. 1, and the related descriptions may refer to each other.

The detection response packet includes detection result information.

As mentioned above, the preset protocol specifies the communication format between the detection device and the communication module, so that the preset protocol not only specifies the communication format for the communication module to inform the detection device of the information such as the function of the pin to be detected and the pin to be detected in the communication module, but also specifies the communication format for the detection device to inform the communication module of the detection result after the detection is completed.

In some embodiments, after the communication module receives the detection response data packet including the detection result information sent by the detection device, the communication module displays information about the detection result through a human-computer interaction interface in the communication module, so that a relevant technician can know whether a pin in the communication module is normal or abnormal, and further subsequent development is facilitated.

In some embodiments, when the pin function to be detected is a GPIO function, the pin function information to be detected includes that the pin function to be detected is a GPIO function, and the identity information of the pin to be detected includes serial numbers of all the GPIO pins to be detected.

In some embodiments, the GPIO function includes a function in which the GPIO output is at a target level, wherein the target level is either a high level or a low level. When the pin function to be detected is a GPIO function, the method for pin detection further includes: in step 101 (or step 201), when the detection device receives the detection request packet, the communication module controls all the GPIO pins to be detected to output the target level. Furthermore, in step 102 (or step 202), the detecting device performs corresponding pin function detection on the pin to be detected in the communication module, including: and the detection equipment detects whether the level output by all the GPIO pins to be detected is the target level. For each GPIO pin to be detected, if the level output by the GPIO pin to be detected currently detected by the detection equipment is the target level, judging that the GPIO function of the GPIO pin to be detected currently is in a normal state; and if the level output by the GPIO pin to be detected currently detected by the detection equipment is not the target level, judging that the GPIO function of the GPIO pin to be detected currently is in an abnormal state.

In some embodiments, when the pin function to be detected is a GPIO function, the detection result specifically includes that all GPIO functions of the GPIO pin to be detected are in a normal state, and at least one GPIO function of the GPIO pin to be detected is in an abnormal state. When the detection result is that all GPIO functions of the GPIO pins to be detected are in a normal state, the detection result information comprises information that all the GPIO functions of the GPIO pins to be detected are in a normal state; and when the detection result is that the GPIO function of at least one GPIO pin to be detected is in an abnormal state, the detection result information comprises information that the GPIO function of at least one GPIO pin to be detected is in the abnormal state and the serial numbers of all the GPIO pins with the GPIO functions in the abnormal state. In some embodiments, the detection result further specifically includes that the detection device cannot detect at least one GPIO pin to be detected. And when the detection result is that the detection device cannot detect at least one GPIO pin to be detected, the detection result information comprises information that the detection device cannot detect at least one GPIO pin to be detected and the serial numbers of all the GPIO pins to be detected, which cannot be detected by the detection device.

The serial number of the GPIO pin can be a pin serial number of the GPIO pin in the communication module or a pin serial number of the GPIO pin in the detection device. And no matter the serial number of the GPIO pin is the serial number of the GPIO pin in the communication module or the serial number of the GPIO pin in the detection equipment, the serial number of the GPIO pin points to the same GPIO pin. Therefore, no matter the serial number of the GPIO pin is the pin serial number of the GPIO pin in the communication module or the pin serial number of the GPIO pin in the detection device, the definitions of the serial numbers of the GPIO pins in the communication module and the detection device need to be unified according to the specific pin connection relationship between the communication module and the detection device, so as to prevent communication between the communication module and the detection device from being incorrect.

In some embodiments, when the pin function to be detected is an ADC function, the pin function information to be detected further includes that the pin function to be detected is an ADC function, and the identity information of the pin to be detected further includes serial numbers of all the ADC pins to be detected.

In some embodiments, when the pin function to be detected is an ADC function, in step 102 (or step 202), the detecting device performs detection on the pin to be detected in the communication module to obtain a detection result, including: the detection equipment detects whether the voltage output by all the ADC pins to be detected is within a preset voltage range. For each ADC pin to be detected, if the detection equipment currently detects that the voltage output by the ADC pin to be detected is within the preset voltage range, judging that the ADC function of the ADC pin to be detected is in a normal state currently; if the detection device currently detects that the voltage output by the ADC pin to be detected is not within the preset voltage range, judging that the ADC function of the ADC pin to be detected is in an abnormal state currently. Under normal conditions, the voltage output by the ADC pin in the communication module is stabilized within a certain voltage range, that is, the preset voltage range, and under normal conditions, the voltage output by the ADC pin in different communication modules is stabilized within different voltage ranges, so that the preset voltage range is different for different communication modules, and the specific preset voltage range is adjusted according to actual conditions.

In some embodiments, when the pins to be detected are ADC functions, the detection result specifically includes that the ADC functions of all the ADC pins to be detected are in a normal state, and the ADC function of at least one ADC pin to be detected is in an abnormal state. When the detection result is that the ADC functions of all the ADC pins to be detected are in a normal state, the detection result information comprises information that the ADC functions of all the ADC pins to be detected are in the normal state; and when the detection result is that the ADC function of at least one ADC pin to be detected is in an abnormal state, the detection result information comprises information about that the ADC function of at least one ADC pin to be detected is in the abnormal state and the serial numbers of all ADC pins in the abnormal state. In some embodiments, the detection result further specifically includes that the detection device cannot detect at least one ADC pin to be detected, and when the detection result is that the detection device cannot detect at least one ADC pin to be detected, the detection result information includes information that the detection device cannot detect at least one ADC pin to be detected, and serial numbers of the ADC pins to be detected that all the detection devices cannot detect.

The serial number of the ADC pin may be a pin serial number of the ADC pin in the communication module, or a pin serial number of the ADC pin in the detection device. No matter the serial number of the ADC pin is the serial number of the ADC pin in the communication module or the serial number of the ADC pin in the detection equipment, the serial numbers of the ADC pins all point to the same ADC pin. Therefore, no matter the serial number of the ADC pin is the serial number of the ADC pin in the communication module or the serial number of the ADC pin in the detection device, the definitions of the serial numbers of the ADC pins in the communication module and the detection device need to be unified according to the specific pin connection relationship between the communication module and the detection device, so as to prevent communication between the communication module and the detection device from being incorrect.

The detection device in the pin detection method provided by the embodiment of the invention has the capability of detecting various functional pins such as GPIO pins, ADC pins and the like, but cannot simultaneously execute the action of detecting various pins with different functions. For example, when the detection device detects the GPIO function of the GPIO pin in the communication module, the ADC function of the ADC pin in the communication module cannot be detected simultaneously, and only when the detection device completes the operation of detecting the GPIO function of the GPIO pin, the operation of detecting the ADC function of the ADC pin can be started. Generally, after the detection device sends one round of the detection response data packet to the communication module, the detection device can receive the next round of the detection request data packet from the communication module for pin detection of different pin functions.

In some embodiments, before step 101 (or 201), the method for pin detection further includes matching between the communication module and the detection device to establish a communication connection between the communication module and the detection device. Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a method for pin detection according to a third embodiment of the present invention:

301. the detection device receives a handshake request packet. The handshake request data packet is generated by the communication module according to the product model of the communication module in a format specified by the preset protocol, and the handshake request data packet includes the product model information of the communication module.

302. And the detection equipment determines the product model of the communication module according to the product model information of the communication module in the handshake request data packet, and matches the product model of the communication module with the communication module to obtain a matching result.

303. And when the detection equipment is successfully matched with the communication module, establishing communication connection between the communication module and the detection equipment.

304. The detection device receives a detection request data packet.

305. The detection equipment determines the functions of the pins to be detected according to the information of the functions of the pins to be detected in the detection request data packet, determines the pins to be detected according to the identity information of the pins to be detected, and detects the corresponding functions of the pins to be detected in the communication module to obtain a detection result.

306. And the detection equipment generates a detection response data packet in a format specified by the preset protocol according to the detection result and sends the detection response data packet to the communication module.

Steps

304, 305, 306 correspond to

steps

201, 202, 203, and the related descriptions can be referred to each other.

As mentioned above, the preset protocol specifies the communication format between the detection device and the communication module, and the communication module informs the detection device of the information about the product model of the communication module through the handshake request data packet, so that the handshake request data packet may also be generated in the format specified by the preset protocol.

The communication module is matched with the detection device, after the detection device is successfully matched with the communication module, communication connection between the communication module and the detection device is established, and meanwhile, initialization work aiming at the current pin detection of the communication module is finished by the detection device according to the product model of the communication module, wherein the initialization work comprises confirming a specific pin of the communication module connected with the detection device and confirming the preset voltage range of the communication module according to the product model of the communication module.

The establishing of the communication connection between the communication module and the detection device is specifically to establish the communication connection between the communication pin in the detection device and the corresponding communication pin in the communication module. The communication connection in this application refers to that the detection device and the communication module can perform data interaction through respective communication pins. The physical connection between the communication pin in the detection device and the corresponding communication pin in the communication module may be established in advance, and only when the detection device and the communication module are successfully matched, which is equivalent to successful handshaking, the communication connection between the communication module and the detection device may be established, that is, the transmission and reception of other non-handshaking request packets may be allowed.

Wherein the matching result comprises a successful matching or a failed matching of the detection device and the communication module. When the matching between the detection device and the communication module is successful, a communication connection between the communication module and the detection device is established, and step 304 and step 306 are further executed. In some embodiments, when the matching between the detection device and the communication module fails, steps 301 and 302 are repeatedly performed until the matching between the detection device and the communication module succeeds, the communication connection between the communication module and the detection device is established, and step 304 and step 306 are further performed.

Referring to fig. 4, fig. 4 is a flowchart illustrating steps of the pin detection method according to a fourth embodiment of the invention:

401. the detection device receives a handshake request packet.

402. And the detection equipment determines the product model of the communication module according to the product model information of the communication module in the handshake request data packet, and matches the product model of the communication module with the communication module to obtain a matching result.

404. And the detection equipment generates a handshake response data packet in a format specified by the preset protocol according to a matching result of successful matching between the detection equipment and the communication module, and sends the handshake response data packet to the communication module.

405. The detection device receives a detection request data packet.

406. The detection equipment determines the functions of the pins to be detected according to the information of the functions of the pins to be detected in the detection request data packet, determines the pins to be detected according to the identity information of the pins to be detected, and detects the corresponding functions of the pins to be detected in the communication module to obtain a detection result.

407. And the detection equipment generates a detection response data packet in a format specified by the preset protocol according to the detection result and sends the detection response data packet to the communication module.

Steps

401, 402 and 403 correspond to

steps

301, 302 and 303,

steps

405, 406 and 407 correspond to

steps

304, 305 and 306, and the related descriptions can be referred to each other.

In some embodiments, if the matching between the detection device and the communication module fails, the detection device generates the handshake response packet in a format specified by the preset protocol according to the matching result of the matching failure between the detection device and the communication module after obtaining the matching result of the matching failure between the detection device and the communication module, and sends the handshake response packet to the communication module. When the communication module receives the handshake response data packet which comprises the matching result of the failure matching between the detection device and the communication module, the handshake request data packet is regenerated and sent to the detection device, and then the detection device repeatedly executes the

steps

401 and 402 until the detection device is successfully matched with the communication module, the communication connection between the communication module and the detection device is established, and then the step 404 is executed.

Wherein the handshake response packet includes matching result information, and when the matching result is that the detection device and the communication module are successfully matched, the matching result information includes information about the successful matching of the detection device and the communication module; when the matching result is that the matching of the detection device and the communication module fails, the matching result information includes information about the failure of matching of the detection device and the communication module.

And when the detection device is successfully matched with the communication module, the detection device generates a handshake response data packet in a format specified by the preset protocol according to a matching result of successful matching between the detection device and the communication module, and sends the handshake response data packet to the communication module so as to inform the communication module that the communication connection is successfully established. And when the communication module knows that the detection device is successfully matched with the communication module, the detection request data packet is generated and sent to the detection device, and then step 405 and 407 are executed.

In some embodiments, before step 401 (or step 301), the method of pin detection further comprises: the communication module obtains the product model of the communication module by reading the configuration file in the communication module, wherein the configuration file is the pre-edited file with a specific format and includes information about the functions of the pins to be detected, the pins to be detected and the like, and the configuration file also includes information about the product model of the communication module.

Therefore, the detection device and the communication module communicate with each other through the aforementioned detection request packet, detection response packet, handshake request packet, handshake response packet, and the like, and each packet is generated in a content format specified by the preset protocol.

With respect to the preset protocol, in some embodiments, the content format specified by the preset protocol sequentially includes: the frame head, the frame type, the data length, the specific data, the check value and the frame tail are six parts.

The frame header part is placed at the beginning of the data packet and used for defining the beginning of the data packet, the size of the space occupied by the frame header part is two bytes, and the specific content comprises 0xF80xF 9; the frame tail is placed at the end of the data packet and used for defining the end of the data packet, the space occupied by the frame tail part is two bytes, and the specific content comprises 0xFD0 xFE.

The frame type part is used for defining the roles of the data packets, and the roles of the data packets are different. The contents included in the frame type part are different.

The data length part is used for representing the total bytes of the specific data part, the representation of the data length part adopts a large-end mode and is transmitted in a hexadecimal form, and the space occupied by the data length part is two bytes.

The specific data portion includes actual specific data received or transmitted between the detection device and the communication module, the content of the actual specific data is defined according to the frame type portion, the content of the frame type portion in the data packet is different, the content of the corresponding specific data portion is different, and the size of the space occupied by the specific data portion is determined by the actual specific data.

The check value part is used for representing the sum of the space occupied by the frame type part, the data length part and the specific data part in the current data packet, the representation of the check value part adopts a large-end mode and is transmitted in a hexadecimal form, and the space occupied by the check value part is two bytes. Since the data content in the data packet may be misplaced or lost during the data transmission, for example, a certain data 0x01 in the data packet may be misplaced to 0x10 or lost during the data transmission, and when the data content is misplaced or lost, the accumulated sum of all or a certain part of the data content may be changed, when the data packet is received by the detection device or the communication module, the first action to be performed is to calculate the data sum of the key data in the current data packet, that is, the accumulated sum of the space sizes occupied by the frame type part, the data length part and the specific data part, and check whether the data sum of the key data in the current data packet is consistent with the check value in the data packet, if the data sum of the key data in the current data packet is consistent with the check value in the data packet, if the sum of the critical data in the current data packet is inconsistent with the check value in the data packet, it is determined that data inaccuracy is possibly caused by misalignment in the transmission process of the data packet, and the data inaccuracy data packet is sent back to the communication module or the detection device sending the data inaccuracy data packet, so that a new data packet is sent back by the communication module or the detection device sending the data inaccuracy data packet. Thus, the check value part is used to check whether the content of the data packet received by the detection device or the communication module is the same as the content of the data packet sent by the communication module or the detection device.

In some embodiments, the content corresponding to different frame types is as follows:
