The invention relates to unattended truck scale automatic detection and control equipment, and belongs to the field of electronic technologies. The invention aims to provide unattended track scale automatic detection and control equipment which can carry out unified management and detection on peripheral equipment, prevents a circumstance that the whole system cannot operate because damages occurred in the peripheral equipment, can prompt problems of the peripheral equipment, is convenient for maintenance and improves the production efficiency of enterprises. According to the invention, a singlechip microcomputer control circuit is respectively communicated with a weighing sensor and an RFID card reader and is connected with an infrared bi-directional radiation detection circuit, a traffic light control circuit, a ground induction coil detection circuit and a switching-value output circuit. The unattended truck scale automatic detection and control equipment is designed in allusion to the current situations, thereby being capable of carrying out unified management and detection on the peripheral equipment of an unattended truck scale system, and being more convenient and efficient in maintenance for the peripheral equipment. The equipment provided by the invention is used for carrying out automatic detection and control on the unattended track scale peripheral equipment of industrial and mining enterprises, and is applied to an unattended truck scale automatic detection system of the industrial and mining enterprises.
Description
technical field [0001] The invention belongs to the field of electronic technology. Background technique [0002] Unattended truck scales are important equipment in industrial and mining enterprises, which need to be connected to a large number of peripheral devices, such as infrared beams, weighing instruments, card readers, ground sensing coils, traffic light control, etc. In order to facilitate maintenance and other work, the existing peripheral devices are basically connected separately, that is, each peripheral device has its own independent system for work and maintenance. There are also some existing ones that connect all peripheral devices in a unified system, but management and maintenance have become difficult problems for industrial and mining enterprises. The damage of one device may cause the entire system to fail to work normally. It takes a lot of time to check and maintain damaged peripheral devices. Time and manpower and material resources have brought sign...
