Detailed Description
The utility model provides a frock of multi-functional communication test CAN be used for detecting whether normal of communication has CAN communication test, communication cable test and battery detection function.
As shown in fig. 1, the multifunctional communication test tool comprises a main control module, and a detection module, a power supply module, a communication and power indication module, a station number and baud rate setting module which are respectively connected with the main control module, wherein the detection module comprises a CAN communication detection module, a communication cable detection module and a battery detection module.
The main control module adopts a main control chip PIC18F46K 80. The power supply module CAN be directly connected with an external power supply for supplying power, a battery CAN also be used for supplying power, and the input voltage is converted into 5V through the K7805 voltage stabilizing chip to supply power to the main control module and the CAN communication detection module.
The station number and baud rate setting module selects 2 16-bit dial switches to be connected with the main control module through a serial port and is used for setting the station number and the baud rate of the main control module.
As shown in fig. 2, the CAN communication detection module adopts a CAN communication module TD531SCANH, mainly adopts CAN communication to detect whether the CAN communication network in the product is normal or not in a fixed CAN protocol manner, and also detects whether the communication of the communication cable in the product is normal or not, and is compatible with the communication cable detection module.
As shown in fig. 3, the communication and power indication module includes a power indication lamp and a communication indication lamp, and the working judgment of the detection module is assisted by the light change of the indication lamp. The communication and power supply indicating module indicates the communication condition by an indicating lamp, when the communication is detected to be normal, a green indicating lamp is on, and when the communication is detected to be abnormal, a red indicating lamp is on; meanwhile, the power indicator is used for indicating the power condition during the battery detection function.
As shown in fig. 4, the battery detection module is configured to detect a 9V battery condition in the power supply module, and detect through setting a voltage sensor, the battery in the power supply module is powered by the 9V battery, when the battery voltage is less than 1.8V, the power indicator lights turn off, indicating that the battery is about to be dead, the battery needs to be replaced in time, the tool can be used normally, when the voltage is greater than 1.8V and less than 5V, the power indicator lights turn on and turn off alternately, indicating that the battery voltage is about to be exhausted, and the battery needs to be prepared for replacement in advance, so as to avoid that the battery is suddenly dead, which affects the use of the tool, and when the battery voltage is greater than 5V, the power indicator lights are on constantly, indicating that the battery voltage is sufficient, and the tool can be used safely.
