Warehouse monitoring system based on signal conditioning

Abstract

The invention discloses a warehouse monitoring system based on signal conditioning. The system comprises a wireless sensor network for monitoring the warehouse environment, a cloud data server, a face recognition module, an illegal opening monitoring module, a wireless transmission module, an automatic opening module, an infrared detection module, an automatic shutdown module, an SMS alarm module, a field acousto-optic alarm module and a real-time monitoring platform. The wireless sensor network comprises gateway nodes, and a plurality of sensor nodes arranged throughout the warehouse. The sensor node comprises a temperature detection module, a light intensity detection module, a smoke sensor and a signal conditioning circuit. The signal conditioning circuit comprises a DC power supply, a first resistor to a tenth resistor, a first capacitor to a fifth capacitor, a first operational amplifier, a second operational amplifier, a triode, a network signal input terminal, and a network signal output terminal. The warehouse monitoring system is based on signal conditioning and can accurately detect the environment in the warehouse, and also can issue an alarm in time.

Description

technical field [0001] The invention relates to the technical field of warehouse monitoring, in particular to a warehouse monitoring system based on signal conditioning. Background technique [0002] With the rapid development of the economy, the scale of storage is getting larger and larger, and the types of materials are also increasing. The traditional human-oriented warehouse monitoring system has become very cumbersome, not only costing money and labor, but also prone to monitoring blind spots. Because of this, a wide variety of warehouse monitoring equipment has emerged as the times require. In recent years, as the Internet of Things technology is increasingly favored by developers, the embedded system based on the Internet of Things technology has injected fresh "blood" into the warehouse monitoring system. [0003] A wireless sensor network is a distributed sensor network whose ends are sensors that can sense and inspect the outside world. The sensors in the wirel...

Problems solved by technology

[0005] However, the existing chemical warehouse monitoring system has a single structure and basically uses pipelines to connect various devices. The transmission range is limited, the wiring is cumbersome, the scalability is insufficient, the transmission method is single, the practical effect is not good, and the alarm cannot be achieved. Synchronous execution with automatic control

The warehouse is an important place for storing, transferring and deploying materials. The storage environment of the warehouse is directly related to the quality of material storage. When the warehouse environment is bad, it may even cause material loss and bring inconvenience to the production of the enterprise. The existing warehouse environment, especially The detection of temperature and humidity, using a temperature and humidity meter, requires the degree of personnel, cannot intuitively display the temperature and humidity values, and cannot send an alarm in time when the temperature and humidity parameters exceed the standard. If the personnel are not on site, it is difficult to understand the exceeding of the temperature and humidity parameters. cause material loss

In some large warehouses stacked with combustibles, fire prevention is the most critical work content. Once a fire occurs, the entire warehouse may be burned down, causing immeasurable losses

However, some items will be stored for too long, and various factors such as fermentation will produce flammable gases. Once there is spark or the temperature is too high, a fire may break out, so detecting the concentration of flammable gases is very critical.
