Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.
Referring to fig. 1, fig. 1 is a schematic diagram of an ambience lamp addressing system 1 according to a first embodiment of the present application. The ambience lamp addressing system 1 comprises: a control module 11; the lighting system comprises at least one atmosphere lamp node 12, wherein the atmosphere lamp node 12 further comprises an input terminal 121 and an output terminal 122, when the number of the atmosphere lamp nodes 12 is 1, the input terminal 121 of the atmosphere lamp node 12 is electrically connected with the control module 11, and the output terminal 122 is vacant; when the number of the atmosphere lamp nodes 12 is at least 2or more, the input terminal 121 of the 1 st atmosphere lamp node 12 is electrically connected to the control module 11, the output terminal 122 of the nth atmosphere lamp node 12 is electrically connected to the input terminal 121 of the (N + 1) th atmosphere lamp node 12, and the output terminal 122 of the last 1 atmosphere lamp node 12 is left empty to form a link circuit, wherein N is greater than or equal to 1, N is smaller than the number of the atmosphere lamp nodes 12, and N is a positive integer; the control module 11 is configured to broadcast a message to all the atmosphere lamp nodes 12 through the link circuit, and address the unaddressed atmosphere lamp nodes 12 one by one according to the sequence of the link circuit.
Specifically, in the present embodiment, each desirable value is taken for N within the range, and the link circuit shown in fig. 1 can be obtained. For example, when the number of atmosphere light nodes 12 is 3, N may be 1, 2. That is, the control module 11 is electrically connected to the input terminal 121 of the 1 st atmosphere lamp node 12, the output terminal 122 of the 1 st atmosphere lamp node 12 is electrically connected to the input terminal 121 of the 2 nd atmosphere lamp node 12, the output terminal 122 of the 2 nd atmosphere lamp node 12 is electrically connected to the input terminal 121 of the 3 rd atmosphere lamp node 12, and the output terminal 122 of the last 1 atmosphere lamp node 12 is left vacant, thereby forming a link circuit.
Specifically, the control module 11 and all the atmosphere lamp nodes 12 form the link circuit, so that the control module 11 can broadcast the packet to all the atmosphere lamp nodes 12 simultaneously in a packet broadcasting process. For example, the control module 11 broadcasts a message to the input terminal 121 of the 1 st atmosphere lamp node 12, the 1 st atmosphere lamp node 12 broadcasts the message to the input terminal 121 of the 2 nd atmosphere lamp node 12 through the output terminal 122 where the first atmosphere lamp node is located, the 2 nd atmosphere lamp broadcasts the message to the input terminal 121 of the 3 rd atmosphere lamp node 12 through the output terminal 122 where the second atmosphere lamp node is located, and so on until the last 1 atmosphere lamp node 12 receives the message.
Specifically, in this embodiment, the control module 11 first addresses the highest-order unaddressed atmosphere lamp nodes 12 in the link circuit, and then addresses the lower-order unaddressed atmosphere lamp nodes 12 in the link circuit. In other words, the control module 11 is addressed in a distance-to-distance manner. This is because in this embodiment the flow direction of the circuit is from far to near to the control module 11, in another possible embodiment it is also possible to go from near to far. The present application is not limited in this respect as long as the control module 11 is not influenced by the automatic addressing of unaddressed ambience light nodes 12.
Specifically, the message includes address information, and when an unaddressed ambience lamp node 12 receives the message including the address information, the control module 11 stores the address of the ambience lamp node 12, so that the control module 11 can call the address of the ambience lamp node 12 to control the ambience lamp node.
It will be appreciated that in this embodiment, the control module 11 may automatically address all unaddressed ambience light nodes 12 via the link circuit. That is, the atmosphere lamp nodes 12 may not be pre-addressed and may be installed at any location, and the control module 11, after the atmosphere lamp nodes 12 are installed, clears all the addresses of the atmosphere lamp nodes 12 through a clear command, and then reenters the process of automatically allocating addresses. Therefore, the cost of manpower and material resources on production and after-sale caused by faults such as wrong installation positions of the atmosphere lamp nodes 12 is saved. The clear command may be issued by an on-board diagnostic device or the like and received by the control module 11.
In a possible embodiment, please refer to fig. 2, and fig. 2 is a schematic diagram of a control module framework according to an embodiment of the present disclosure. The control module 11 includes: the message processing system comprises a processor 111 and a message transmitter 112, wherein the processor 111 is used for compiling a message and transmitting the message to the message transmitter 112; the message transmitter 112 is configured to broadcast a message to all atmosphere light nodes 12 through the link circuit.
Specifically, the message transmitter 112 may be a Local Interconnect Network (LIN) transmitter. The LIN transmitter is one of the more commonly used vehicle-mounted communication modes for transmitting messages, and the LIN can provide an auxiliary function for a vehicle-mounted communication network. In this embodiment, the LIN transmitter broadcasts messages to all atmosphere lamp nodes 12, which can greatly save cost. Of course, the present application does not limit the type of the message transmitter 112 as long as the message transmitter 112 does not affect the broadcast of messages to all atmosphere light nodes 12.
In a possible embodiment, please refer to fig. 3, and fig. 3 is a schematic diagram of a control module framework according to an embodiment of the present application. The control module 11 further comprises: a command receiver 113, the command receiver 113 for receiving an automatic addressing command; and the processor 111 starts to write the message according to the automatic addressing command.
Specifically, the command receiver 113 may be a Controller Area Network (CAN) receiver, which is commonly used in an on-board Network and CAN communicate with other on-board controls.
In particular, the automatic addressing commands are typically externally manually entered commands. For example, in the production process, after the atmosphere lamp is installed in the atmosphere lamp node 12, an automatic addressing command can be input to start addressing the atmosphere lamp node 12; for another example, in the using process, when a certain atmosphere lamp is damaged and needs to be replaced, after a new atmosphere lamp is installed in the atmosphere lamp node 12, the automatic addressing command can be input, and the atmosphere lamp node 12 starts to be addressed.
The circuit principle of the ambience lamp node 12 will be explained in detail below. In one possible embodiment, please refer to fig. 4, in which fig. 4 is a schematic diagram of an atmosphere lamp node circuit according to an embodiment of the present disclosure. Each atmosphere light node 12 further comprises: the message receiver 123, the message receiver 123 is electrically connected to the input terminal 121 of the atmosphere lamp node 12, and is configured to receive the message; and a shunt resistor Rshunt, one end of the shunt resistor Rshunt is electrically connected to the input terminal 121 of the atmosphere lamp node 12, and the other end of the shunt resistor Rshunt is electrically connected to the output terminal 122 of the atmosphere lamp node 12, and the shunt resistors Rshunt of all the atmosphere lamp nodes 12 form a bus of the link circuit.
Specifically, as shown in fig. 4, the message receiver 123 may be a LIN receiver corresponding to the message transmitter 112. It can be understood that, in this embodiment, since the shunt resistance Rshunt is about 1 Ω, and the input terminal 121 and the output terminal 122 of a single atmosphere light node 12 are not completely electrically isolated, the control module 11 may broadcast a message to all atmosphere light nodes 12 through the link circuit at the same time.
In one possible embodiment, referring to fig. 5, fig. 5 is a circuit diagram of an ambience lamp addressing system according to an embodiment of the present application. The control module 11 further comprises: a power supply module Vs for providing electrical energy; each atmosphere light node 12 further comprises: a pull-up resistor Rpu and a pull-up resistor switch ENpu, wherein one end of the pull-up resistor Rpu is electrically connected to the power supply module Vs, the other end of the pull-up resistor Rpu is electrically connected to the pull-up resistor switch ENpu, the other end of the pull-up resistor switch ENpu is electrically connected to a node where the input terminal 121 is electrically connected to the shunt resistor Rshunt, when the message receiver 123 receives the message from the beginning of addressing, the pull-up resistor switch ENpu is electrically connected to the processor 111 and is turned off under the control of the processor 111, the processor 111 measures the current of each atmosphere lamp node 12 on the bus to obtain a first offset current, the pull-up resistor switch ENpu is turned on under the control of the processor 111, the processor 111 measures a second offset current of each atmosphere lamp node 12 on the bus again and calculates a first difference between the second offset current and the first offset current, and preliminarily judging the position of each atmosphere lamp node 12 in the link circuit according to the first difference value.
Specifically, in this embodiment, the power supply module Vs may be a High-side Driver (HSD) chip, and the HSD chip is more commonly used for the power supply function of the vehicle-mounted controller, and has the advantages of self-protection, High integration level, and the like. The power supply module Vs is electrically connected to each of the atmosphere lamp nodes 12 to generate power supply energy, and the voltage provided by the power supply module Vs is 12V.
Specifically, in this embodiment, the pull-up resistor Rpu is 30k Ω offset current, which is a name for the current measured on the bus. The first offset current is a current value measured when the pull-up resistance switch ENpu is turned off, and the first offset current is used as a zero calibration quantity. The second offset current values measured on the bus line of each atmosphere lamp node 12 will be different from each other after the pull-up resistance switch ENpu is turned on. Then, it can be determined from the first difference that the atmosphere lamp node 12 with the larger first difference is closer to the control module 11 in the link circuit, and the atmosphere lamp node 12 with the smaller first difference is farther from the control module 11 in the link circuit. Thus, the control module 11 may determine the sequential relationship of all atmosphere lamp nodes 12 in the link circuit.
In one possible embodiment, referring again to fig. 4 and 5, each atmosphere light node 12 further includes: a pull-up current source Iaa and a pull-up current source switch ENaa, wherein one end of the pull-up current source Iaa is electrically connected to the power supply module, the other end of the pull-up current source Iaa is electrically connected to the pull-up current source switch ENaa, the other end of the pull-up current source switch ENaa is electrically connected to a node where the input terminal 121 is electrically connected to the shunt resistor Rshunt, when the first difference is smaller than or equal to a preset threshold, the pull-up current source switch ENaa is electrically connected to the processor 111 and is turned on under the control of the processor 111, the processor 111 measures a third offset current on the bus and calculates a second difference between the third offset current and the first offset current, and when the second difference is smaller than or equal to the preset threshold, the message receiver 123 receives the address in the message.
Specifically, in this embodiment, the current value of the pull-up current source Iaa is 2mA, and turning on the pull-up current source Iaa may make the current value measured on the bus significantly larger than the current value measured when turning off the pull-up current source Iaa, so as to better distinguish the sequence of the atmosphere lamp node 12 in the link circuit. In the present embodiment, the preset threshold is set to 1 mA.
Specifically, referring to fig. 4 again, the atmosphere lamp node 12 further includes a differential voltage circuit Uaa, one end of the differential voltage circuit Uaa is electrically connected to one end of the shunt resistor Rshunt, and the other end of the differential voltage circuit Uaa is electrically connected to the other end of the shunt resistor Rshunt. The differential voltage circuit Uaa may reduce common mode interference signals, so that the first offset current, the second offset current, and the third offset current measured by the processor 111 are more accurate.
Specifically, please refer to fig. 6, in which fig. 6 is a schematic diagram of an automatic addressing process according to an embodiment of the present application. If the first difference is greater than the preset threshold, after the processor 111 detects the first differences of all the atmosphere lamp nodes 12, turning off the pull-up resistor switches ENpu where all the atmosphere lamp nodes 12 are located. And if the second difference is greater than the preset threshold, turning off the pull-up current source switches ENaa where all the atmosphere lamp nodes 12 are located. After turning on the pull-up resistor switches enu where all the atmosphere lamp nodes 12 are located and turning off the pull-up current source switches ENaa, the control module 11 detects whether all the atmosphere lamp nodes 12 are addressed and ends the automatic addressing procedure.
It can be understood that, in the present embodiment, the relationship between the first difference and the second difference of each atmosphere lamp node 12 and the preset threshold is determined, so that it is possible to avoid that the current value of the bus load is too large, which may cause damage to the atmosphere lamp node 12. By calculating the first difference and the second difference of each atmosphere lamp node 12, the sequence of the atmosphere lamp nodes 12 from the control module 11 in the link circuit can be accurately obtained, and thus, addressing is performed.
The messages written by the processor 111 will be briefly described below. Referring to fig. 7, fig. 7 is a schematic diagram of a message format according to an embodiment of the present application.
