Embodiment 1
[0046]The embodiment of the present invention provides a fire alarm method for an excavator, which is implemented based on an excavator fire alarm device. The excavator fire alarm device includes a voltage and current conversion device, a rectifier device, an early warning device and an alarm device. The voltage-current conversion device is used to detect the change of current in the power supply circuit of the excavator and generate a voltage signal; the rectification device is electrically connected to the voltage-current conversion device, and the voltage signal is rectified to obtain a step trigger signal, and the step trigger signal includes It has switch values with different values; the early warning device is electrically connected with the rectifier device to output an early warning signal when the switch value reaches the set value; the alarm device is electrically connected with the early warning device to receive the early warning signal, activate the alarm circui...
Embodiment 2
[0064] The embodiment of the present invention provides a fire alarm system for an excavator, refer to image 3 ,include:
[0065] The early warning module 201 is used to detect the current signal of the power supply circuit of the excavator, generate a voltage signal, rectify the voltage signal to obtain a step trigger signal, and issue an early warning signal when the switching value of the step trigger signal reaches a set value; this module It is used to execute the method described in steps S101 to S103 in Embodiment 1, and details are not described herein again.
[0066] The control module 202 is used for receiving an early warning signal and sending a control signal; the controller can select a single-chip microcomputer with low power consumption. This module can be used to execute step S104 and step S105 in Embodiment 1.
[0067] The execution module 203 is used for receiving the control signal, detecting the temperature of the inspection item of the excavator, and s...
Embodiment 3
[0073] This embodiment provides a computer device, refer to Figure 5 , the computer device includes a processor 301 and a memory 302, wherein the processor 301 and the memory 302 can be connected by a bus or in other ways, Figure 4 Take the connection through the bus as an example.
[0074] The processor 301 may be a central processing unit (Central Processing Unit, CPU). The processor 301 may also be other general-purpose processors, a digital signal processor (Digital Signal Processor, DSP), a graphics processor (Graphics Processing Unit, GPU), an embedded neural network processor (Neural-network Processing Unit, NPU), or other Dedicated deep learning coprocessors, Application Specific Integrated Circuits (ASICs), Field-Programmable Gate Arrays (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components and other chips, or a combination of the above-mentioned types of chips.
[0075] As a non-transitory computer-r...
