In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
On the first hand, as shown in fig. 1, the mechanical pointer type automobile clock system according to the embodiment of the invention comprises a bus module 100, a main control module 200, a clock motor 300 and an infrared system module 500; the main control module 200 is electrically connected to the bus module 100, the clock motor 300 and the infrared system module 500, respectively.
Specifically, the bus module 100 may be self-contained in the vehicle itself, and is used for sending various signals, such as a clock signal, a vehicle start signal, and the like, to the main control module 200. The main control module 200 may adopt a microprocessor such as an MCU and peripheral circuits thereof, and is configured to control the operating states of the clock motor 300 and the infrared system module 500; the main control module 200 is provided with a program for controlling the running Time of the car Clock 400 and an RTC (Real _ Time Clock). The clock motor 300 is used for driving the automobile clock 400 to move according to the instruction of the main control module 200. The infrared system module 500 is configured to transmit and receive an infrared signal according to an instruction of the main control module 200 to obtain a mechanical zero point of the clock motor 300; the infrared system module 500 includes an infrared transmitting tube and a receiving tube.
The mechanical pointer type automobile clock system provided by the embodiment of the invention has the following specific working principle:
first, when the system is connected to the car power supply and powered on, it is necessary to find the mechanical zero point of the clock motor 300 first, so as to perform time initialization. In order to find the mechanical zero point of the clock motor 300, the clock motor 300 can drive the automobile clock 400 to rotate counterclockwise by a certain angle, and in the rotating process, the infrared system module 500 transmits and receives infrared signals, so as to detect the mechanical zero point of the clock motor 300, and if the mechanical zero point is detected, the mechanical zero point is taken as the clock zero point of the automobile clock 400; if the mechanical zero point is not detected after the counterclockwise rotation reaches the preset angle, the clock motor 300 drives the automobile clock 400 to start the clockwise rotation until the mechanical zero point is found.
Secondly, after finding the mechanical zero point, taking the mechanical zero point as the clock zero point of the automobile clock 400; meanwhile, the main control module 200 receives the time signal of the bus module 100, and according to the time signal, the clock motor 300 drives the vehicle clock 400 to rotate counterclockwise or clockwise in the shortest route to the corresponding time, and then starts to walk from the time.
In order to save the power consumption of the battery of the vehicle, the vehicle clock 400 may be operated in an operating mode or a sleep mode according to whether the vehicle is in a start state or a stop state. The bus module 100 sends different signals to the main control module 200 according to different states of the vehicle, and the main control module 200 controls the clock motor 300 to drive the vehicle clock 400 to travel in two different ways. If the automobile is in a starting state, when the automobile clock 400 walks in a working mode, the automobile clock 400 is accurate in real time in a micro-walking mode and is not easy to be perceived by naked eyes, so that the walking time of the automobile clock 400 is more refined, and a client can conveniently observe time at any time; if the automobile is in a flameout state, when the automobile clock 400 walks in a sleep mode, the automobile clock 400 jumps once per minute, so that the power consumption of the mechanical pointer type automobile clock system is reduced. Through setting up two kinds of different travel time modes, can reduce the power consumptive property of mechanical pointer formula car clock system effectively, save the power consumption.
Meanwhile, an RTC (real time clock) is provided inside the main control module 200, and the RTC is used for indicating the time of the car clock 400. When the RTC reaches the position of 12 points, namely the zero point position, the position is compared with the mechanical zero point of the clock motor 300, if an error is found, the time indicated by the automobile clock 400 is corrected in time to be consistent with the RTC, so that the travel time of the automobile clock 400 is more accurate.
In addition, in the process of the automobile clock 400 running, the RTC is compared with the time sent by the bus module 100 in real time, and if an error is found, the time of the RTC is corrected in time, so that the time of the automobile clock 400 is accurate. The specific correction method comprises the following steps: when the RTC time and the bus time have errors, different corresponding strategies are adopted according to the speed of the RTC time; if the RTC time is faster than the bus time and exceeds 1min, the clock motor 300 drives the automobile clock 400 to rotate counterclockwise to the bus time; when the RTC time is faster than the bus time and does not exceed 1min, the automobile clock 400 stops rotating, and the automobile clock waits for the RTC time to be consistent with the bus time and then goes; when the RTC time is slower than the bus time, the clock motor 300 drives the automobile clock 400 to rotate clockwise quickly to catch up with the bus time. The biggest advantage of the above strategy is that the time calibration process of the automobile clock 400 does not always have the situation of swinging the pointer left and right, so that the user is not easy to find the time calibration process, and the misjudgment of the user on the product as a fault is avoided.
In addition, as shown in fig. 1, in some embodiments of the present invention, the mechanical pointer type car clock system further includes a backlight module 600, and the backlight module 600 may be composed of a switch tube and an LED lamp, and the main control module 200 controls the on/off and the brightness of the LED lamp. After the main control module 200 receives the noctilucent mode signal transmitted from the bus module 100, the main control module 200 controls the backlight module 600 to emit light and can control the light emitting brightness by controlling the current, so that the automobile clock 400 is sparkling and vivid at night, is beautiful and beautiful in atmosphere, supports the interior of the automobile, and improves the automobile taste.
In a second aspect, as shown in fig. 2, a travel time method of a mechanical pointer type automobile clock according to an embodiment of the invention includes the following steps:
step S100: the mechanical zero of the clock motor 300 is acquired and used as the clock zero of the automobile clock 400.
Specifically, after the mechanical pointer type car clock system is connected to the car power supply and powered on, it is first required to find the mechanical zero point of the clock motor 300, so as to perform time initialization. In order to find the mechanical zero point of the clock motor 300, the clock motor 300 may drive the automobile clock 400 to rotate counterclockwise by a preset angle, and in the rotating process, the infrared system module 500 transmits and receives an infrared signal, thereby detecting whether the mechanical zero point of the clock motor 300 exists within the range of the preset angle; if the mechanical zero point exists, the mechanical zero point is taken as the clock zero point of the automobile clock 400; if the clock signal does not exist, after the automobile clock 400 rotates counterclockwise by the preset angle, the clock motor 300 drives the automobile clock 400 to start rotating clockwise until the infrared system module 500 detects a mechanical zero point of the clock motor 300, and the mechanical zero point is used as a clock zero point of the automobile clock 400, thereby completing time initialization.
Step S200: the vehicle clock 400 is driven to rotate from the clock zero to the corresponding first position according to the time signal provided by the bus module 100.
Specifically, after finding the mechanical zero point of the clock motor 300, the mechanical zero point is taken as the clock zero point of the automobile clock 400; meanwhile, the main control module 200 receives the time signal provided by the bus module 100, and according to the time signal, the clock motor 300 drives the vehicle clock 400 to rotate counterclockwise or clockwise to a corresponding first position in the shortest route.
Step S300: the car clock 400 starts from the first position and travels.
Specifically, the vehicle clock 400 may travel in two modes, an active mode and a sleep mode. The bus module 100 sends different signals to the main control module 200 according to different states of the vehicle, and the main control module 200 controls the clock motor 300 to drive the vehicle clock 400 to travel in two different ways. If the automobile is in a starting state, the automobile clock 400 enters a working mode, and in the working mode, the automobile clock 400 walks according to a first preset rule; if the vehicle is in a flameout state, the vehicle clock 400 enters a sleep mode, and in the sleep mode, the vehicle clock 400 walks according to a second preset rule.
The first preset rule may be: the clock motor 300 controls the car clock 400 to walk in a micro-step manner. The automobile clock 400 adopts a micro-walking mode, is real-time and accurate, and is not easy to be perceived by naked eyes, so that the walking time of the automobile clock 400 is more refined, and is easy to be approved by customers.
The second preset rule may be: the car clock 400 rotates once every first preset time when walking. The first preset time may be 1min, or 30s, or other reasonable time.
According to the starting mode and the flameout mode of the automobile, when the automobile clock 400 walks in a working mode and a sleep mode, the power consumption of the mechanical pointer type automobile clock system is effectively reduced, and the power consumption is saved.
Step S400: in the travel process, the time of the automobile clock 400 is compared with the time provided by the bus module 100, and the time of the automobile clock 400 is corrected according to the comparison result.
Specifically, the master control module 200 is provided therein with an RTC (real time clock) for indicating the time of the car clock 400. In the process of the automobile clock 400 running, the RTC time is compared with the time sent by the bus module 100 in real time, and if an error is found, the RTC time is corrected in time, so that the time of the automobile clock 400 is accurate.
The correction method comprises the following steps: if the time of the automobile clock 400 is faster than the time provided by the bus module 100, the automobile clock 400 is driven to rotate counterclockwise or stop rotating, so that the time of the automobile clock 400 is the same as the time provided by the bus module 100; if the time of the car clock 400 is slower than the time provided by the bus module 100, the car clock 400 is driven to rotate clockwise, so that the time of the car clock 400 is the same as the time provided by the bus module 100.
More specifically, when the RTC time and the bus time have errors, different corresponding strategies are adopted according to the speed of the RTC time; if the RTC time is faster than the bus time and exceeds 1min, the clock motor 300 drives the automobile clock 400 to rotate counterclockwise to the bus time; when the RTC time is faster than the bus time and does not exceed 1min, the automobile clock 400 stops rotating, and the automobile clock waits for the RTC time to be consistent with the bus time and then goes; when the RTC time is slower than the bus time, the clock motor 300 drives the automobile clock 400 to rotate clockwise quickly to catch up with the bus time. The biggest advantage of the above strategy is that the time calibration process of the automobile clock 400 does not always have the situation of swinging the pointer left and right, so that the user is not easy to find the time calibration process, and the misjudgment of the user on the product as a fault is avoided.
In addition, when the RTC reaches the position of 12 points, namely the zero point position, the RTC is compared with the mechanical zero point of the clock motor 300, and if an error is found, the time indicated by the automobile clock 400 is corrected in time to be consistent with the RTC, so that the travel time of the automobile clock 400 is more accurate.
According to the mechanical pointer type automobile clock system and the timing method of the clock system, the accuracy of the timing of the automobile clock 400 can be effectively guaranteed, and the power consumption of the whole system can be reduced.
