All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic structural diagram of a battery voltage detection system according to the present invention is shown, the system includes a RKE product 100 carrying a battery, and a RKE test equipment 200. In particular, the amount of the solvent to be used,
the RKE product 100 of the present invention has the function of self-detecting battery voltage, generating battery voltage information, and transmitting the battery voltage information.
The RKE test device 200 is configured to trigger the RKE product 100 to perform self-detection on the battery voltage according to a received user test instruction, generate and send battery voltage information, and the RKE test device 200 receives the battery voltage information and judges whether the battery is normal according to the battery voltage information.
It should be noted that the RKE test device 200 of the present invention may mechanically touch and press the corresponding physical key or button of the RKE product 100 in a mechanical contact manner, thereby controlling the RKE product 100 to perform self-test of the battery voltage, generating and sending the battery voltage information, or may send a control signal to the RKE product 100 to control the RKE product 100 to perform self-test of the battery voltage, generating and sending the battery voltage information. When the RKE test device 200 controls the RKE product 100 to self-test the battery voltage, generate and transmit the battery voltage information by sending a control signal to the RKE product 100, the RKE product 100 needs to have a function of receiving and responding to the control signal.
In the practical application of the present invention, the RKE product 100 may be placed in the RKE test device 200, and in particular, the RKE test device 200 is provided with a first space for loading the RKE product 100. The first space is a groove matching the shape and size of the RKE product 100.
To facilitate a clearer description of the solution of the invention, the invention first introduces the RKE test device 200. Preferably, in order to reduce the wireless power consumption problem of the RKE product 100, the RKE test device 200 is in mechanical contact with the RKE product 100, and the specific structural form of the RKE test device 200 is shown in fig. 2 and comprises an RKE key triggering mechanical module 201, an information receiving module 202 and an information processing module 203. Wherein,
the RKE key triggering mechanical module 201 is configured to, according to a received user test instruction, press a key to trigger an action button of the RKE product 100, so that the RKE product 100 performs self-detection on the battery voltage, and generates and sends out the battery voltage information.
In this embodiment, the RKE key triggering mechanical module 201 may be specifically a manipulator, and when the user touches and presses a test switch of the RKE test device 200, the RKE test device 200 receives a test instruction of the user, and then controls the manipulator to press a key to trigger an action button of the RKE product 100 according to the test instruction. The action buttons of the RKE product 100 may include an unlock button, a lock button, a seek button, a trunk unlock button, etc.
A message receiving module 202 for receiving battery voltage information from the RKE product 100.
The specific information receiving module 202 may be a wireless signal transceiver.
The information processing module 203 is configured to analyze the battery voltage information to obtain a battery voltage value, compare the battery voltage value with the preset voltage value, and determine whether the battery in the RKE product 100 is normal according to a comparison result. In addition, the information processing module 203 of the present invention can also output and display the battery voltage value obtained by analyzing the battery voltage information and the comparison result.
In the present invention, the information processing module 203 is preset with a normal preset voltage value. The information processing module 203 firstly analyzes the battery voltage information to obtain the battery voltage value of the currently measured battery, and then compares the analyzed battery voltage value with a preset voltage value to judge whether the battery is normal according to the comparison result. For example, the preset voltage value is 3.0V, and when the measured battery voltage value of the battery is 2.1V, it is much smaller than the preset voltage value of 3.0V because it can be judged that the battery is abnormal.
Of course, the information processing module 203 of the present invention may also preset a normal preset voltage range, and when the measured battery voltage value of the battery is not within the preset voltage range, it indicates that the battery is abnormal.
Further, the RKE product 100 of the present invention is described.
The RKE product 100 of the present invention has at least the following features:
(1) the RKE product 100 is capable of self-testing battery voltage and generating battery voltage information.
Specifically, a battery voltage AD acquisition circuit or the like may be provided in the RKE product 100 to perform self-detection of the voltage of the battery in the RKE product 100.
(2) The RKE product 100 is capable of signaling battery voltage information.
After the RKE product 100 completes the voltage self-detection and generates the battery voltage information, the battery voltage information needs to be sent out.
In the actual working process, the RKE product 100 is in a wireless working mode, and information interaction is completed through radio frequency information. In the present invention, when the user touches the action button of the RKE product 100 to start the operation of the RKE product 100, the RKE product 100 transmits a frame of radio frequency information, which includes corresponding button information, for example, when the user touches the unlock button of the RKE product 100, the radio frequency information includes unlock button information, and when the user touches the lock button of the RKE product 100, the radio frequency information includes lock button information. Therefore, the invention can carry the battery voltage information generated after the RKE product 100 completes the voltage self-detection in the radio frequency information and send the battery voltage information through the radio frequency information. At this point, the RKE test device 200 receives the radio frequency information and obtains battery voltage information therefrom.
In addition, it is preferable that if the RKE product 100 acquires the battery voltage information of the RKE battery through the battery voltage AD acquisition circuit, the battery voltage information is an AD signal. And because the AD signal is generally 8-bit or 10-bit information, it may occupy more wireless signal resources during the transmission process, and may even affect the implementation of other wireless functions of the RKE product 100. Therefore, the present invention proposes to segment the range of the battery voltage in advance to generate a plurality of preset voltage ranges, for example, the battery voltage range is pre-divided into 5 voltage value sub-ranges shown in fig. 3, which are 0-2.68V, 2.69-2.80V, 2.81-2.89V, 2.90-2.99V and greater than 2.99V. Furthermore, a predetermined digital value, for example 0, 1, 2, 3, 4, is set for each voltage value sub-range, and a typical voltage value corresponding to each voltage value sub-range can also be set. When the battery voltage information is sent, firstly, a preset voltage range corresponding to the battery voltage value is determined according to the battery voltage value obtained after self-detection, then, according to the preset voltage range, the battery voltage value obtained after self-detection is processed into a preset digital quantity corresponding to the preset voltage range, and the corresponding preset digital quantity 0, 1, 2, 3 or 4 is sent out as the battery voltage information, for example, the battery voltage value obtained after current self-detection is 2.75V, and 2.75V is located in a preset voltage value sub-range of 2.69-2.80V, so that the 2.75V is processed into the digital quantity 1 to be sent out, and thus, fewer digital quantities can be used for replacing an AD signal, and transmission resources of wireless signals are saved.
By applying the technical scheme of the invention, the battery voltage detection system provided by the invention comprises the RKE product 100 carrying the battery and the RKE test equipment 200 which can be in mechanical contact with the RKE product 100. When the electric quantity of the battery in the RKE product 100 needs to be measured, the RKE test device 200 triggers the RKE product 100 to perform self-detection on the battery voltage, generates and sends out battery voltage information, and then the RKE test device 200 receives the battery voltage information and judges whether the battery is normal or not according to the battery voltage information. The voltage of the battery in the working state is measured, and the online on-load detection of the battery is realized, so that the measured voltage of the battery is more consistent with the actual voltage of the battery, the measurement precision is improved, and the accuracy of the test result of whether the battery in the RKE product is normal is improved.
The battery voltage detection system, the RKE test equipment and the RKE product provided by the invention are described in detail, specific examples are applied in the description to explain the principle and the implementation mode of the invention, and the description of the examples is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
