Embodiment
[0051] In order to facilitate those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below with specific examples:
[0052] In this embodiment, it is necessary to consider the maximum detection ranges of different types of programmable sensor modules. Since the resistance range of the digital control potentiometer is smaller, the precision is higher, so it is necessary to use a digital control potentiometer with a detection range similar to that of the programmable sensor module in the production, so as to improve the accuracy of the test. At the same time, an appropriate number of digitally controlled potentiometers can also be selected according to the maximum number of interfaces of the programmable sensor module. In this embodiment, a three-way programmable sensor module is taken as an example for a detailed introduction.

The invention provides an automatic test method and device for a programmable sensor module. The device comprises a power supply module, a CAN module, a FLASH module, an MCU module, a serial port conversion module, a programmable numerical control potentiometer module and an indicating lamp module which are arranged on a circuit board. The device is simple to operate and high in efficiency; when in use, all programmable sensor interfaces can be tested only by connecting a programmable sensor module interface and a CAN interface, and software is used for self-testing, so that the test is accurate, and the test time is greatly saved; secondly, a curve can be freely set; programmable sensor modules with different sensor characteristic curves can be programmed in the FLASH module; thirdly, the protectiveness is good; in the automatic detection process, human participation is not needed, and the generator set controller can be prevented from being damaged due to misoperation of testers; meanwhile, the size is small, carrying is convenient, and convenience can be provided for testers; meanwhile, multiple sensor interfaces are provided, and simultaneous testing can be achieved.
Description
technical field [0001] The invention relates to the field of programmable sensors, in particular to an automatic testing method and device for a programmable sensor module. Background technique [0002] Diesel generator set is a kind of mechanical and electrical integration equipment. It consists of three major components: diesel engine, alternator and unit electrical control system, including the front-end oil supply system and the rear-end power supply system, forming a complete energy supply management system. [0003] The generator set controller is the core part of the electrical control system of the generator set, which can achieve various control effects on the diesel generator set by collecting the working parameters of the diesel generator set. Including power generation monitoring, city power monitoring, automatic switching control and other functions, it is an integrated control and monitoring system for power generation and city power. [0004] The programmable...
