Dangerous mixed storage and overtime storage of dangerous goods are avoided, dangerous goods storage risks are identified in advance, reminding information is generated in time, and safety of warehouse storage is guaranteed from the source.
Further, dividing the warehouse into a plurality of storage areas according to preset rules; acquiring the temperature, the humidity and the marker gas concentration of each storage area as the environmental parameters in the warehouse, wherein the temperature and the humidity of a fixed monitoring point in the corresponding storage area and the temperature and the humidity of a real-time movable monitoring point in the corresponding storage area are acquired, and at least one fixed monitoring point and one movable monitoring point are arranged in the same storage area; and simultaneously acquiring the marker gas concentration information of each marker gas concentration monitoring point in the corresponding storage area, wherein a plurality of marker gas concentration monitoring points are arranged in the warehouse area.
In the embodiment of the invention, as shown in fig. 2, in order to avoid mixed storage of dangerous goods with dangerous risks, ensure that the warehouse can perform diversified goods storage types, and improve the warehouse storage efficiency, the storage warehouse is divided into a plurality of storage areas, corresponding area arrangement is performed according to the goods storage types, for example, diversified storage areas such as a conventional goods storage area, a moisture-proof goods storage area, and a dangerous goods storage area are distinguished, and corresponding storage areas are warehoused according to the warehoused goods types. Although each storage area shares one warehouse, the goods stored in each storage area are different, and the environmental parameters for safe storage between different goods are different, so that the detection needs to be carried out on the corresponding safe storage environments of different goods storage areas. Even though all storage areas may not be completely separated by walls, air circulation causes the environmental parameters of each storage area to have certain similarity, but part of stored goods may dissipate heat, emit certain gases, evaporate water vapor and the like, so that the environmental parameters of a specific storage area are different from those of a nearby area and a remote area by various levels, and therefore, in order to ensure that targeted on-site environmental monitoring can be carried out on different storage areas, the environmental monitoring devices of each storage area are independent and systematic.
Preferably, a complete environmental monitoring device is arranged in each area, and the temperature, the humidity and the marker gas concentration of the area are respectively monitored. Some goods require severe environmental conditions for storage, and hazardous articles are more dangerous, for example, the storage temperature required by wet inflammable goods is often lower than 30 ℃, the humidity is lower than 80%, and the hazardous articles cannot be mixed with combustion-supporting gas and highly toxic gas, and in order to prevent safety problems of some hazardous articles due to environmental problems, various environmental parameters of the storage area corresponding to the hazardous articles need to be acquired in real time.
As shown in fig. 2, preferably, in order to avoid the failure of the environmental parameter collecting device or the overhigh local parameter of a certain point, the same environmental monitoring device in the same area is provided in multiple numbers, for example, if an abnormal local temperature is caused by an abnormal situation of a certain box cargo in a certain area, and the temperature monitoring device is located at other positions in the area, the abnormal point is not found in time, so that the safety accident is caused by the timely processing, so as to accurately and timely obtain the environmental parameter in the storage area, the multiple environmental monitoring devices are preferably provided, wherein the temperature monitoring device and the humidity monitoring device can be fixed or non-fixed, because the local temperature or humidity may be overhigh in the same storage area, and the fully fixed detection device still has a monitoring blind area, so that the mobile monitoring device is provided to patrol and monitor in a certain area according to a preset rule, the monitoring blind area does not exist in the whole area, and all possible emergency situations can be acquired by the monitoring device in real time; for the gas concentration, because the air mobility is strong, the same marker gas concentration value at each position in the warehouse at the same time is the same, in order to avoid redundant arrangement of the marker gas concentration sensors, it is preferable that only a marker gas concentration monitoring point (each monitoring point is provided with a set of marker gas concentration sensor for monitoring the concentration of a plurality of different marker gases) is required to be arranged at a plurality of positions in the warehouse, and a single set of marker gas concentration sensor is not required to be arranged in each storage area, and the arrangement positions are preferably evenly arranged according to the warehouse environment, but are not limited in a fixed or movable mode.
Further, comparing the temperature of each fixed monitoring point and the temperature of each movable monitoring point in the same storage area, and taking the highest temperature value as the judgment temperature of the storage area; marking the humidity average value of the humidity of all the fixed monitoring points in the same storage area as the fixed judgment humidity of the storage area, and marking the humidity average value of the humidity of all the movable monitoring points in the same storage area as the movable judgment humidity of the storage area; for one storage area, all the corresponding marker gas concentrations of the marker gas concentration monitoring points in the warehouse are acquired, and for the same marker gas, the average concentration value of the marker gas concentrations of the marker gas concentration monitoring points is used as the marker gas judgment concentration of the marker gas in the storage area.
In the embodiment of the invention, various abnormal situations may occur during the storage of goods, for example, when a certain storage area stores heated inflammable matters, a local part is irradiated by sunlight, so that the local temperature of the part is higher than the temperature of other positions in the same storage area, if the average value of all the position temperatures of the storage area is the real-time environment temperature of the storage area, the problem of too high local temperature cannot be timely detected, the stored goods at the position are caused to be self-ignited due to too high local temperature, and thus other goods are ignited to cause a safety accident. Therefore, in order to avoid the problem that the local temperature is too high, the fixed temperature sensor and the mobile temperature sensor are operated at the same time, and when the local temperature is found to be too high, the local temperature is regarded as the ambient temperature of the entire storage area, and even if the temperature at other positions is within the safe storage temperature threshold, if the local temperature is higher than the safe storage temperature threshold, it indicates that the cargo is in an abnormal storage state, and warning information is generated.
The humidity of each area of the warehouse can have large difference, even if the same storage area is adopted, the types of stored goods and the storage quantity of the goods can cause the difference of the humidity of each position, in order to accurately monitor the humidity of different storage areas, the humidity judgment values of a mobile detection point and a fixed monitoring point are preferably distinguished, and the mobile judgment humidity and the fixed judgment humidity are compared with the safe storage humidity threshold value of the stored goods, so that the omnibearing monitoring of the humidity of the safe storage of the goods is ensured.
For the gas concentration, because the gas mobility is strong, in order to avoid redundant arrangement of the marker gas concentration sensors, a plurality of positions can be averagely arranged on the whole warehouse as marker gas concentration monitoring points, each marker gas is provided with a specific sensor device, the sensor devices corresponding to the gases are also a plurality, namely, the same type of sensor is a gas concentration monitoring array, and a plurality of different gas concentration monitoring arrays are combined into a complete marker gas concentration monitoring system of the warehouse. For example, since goods affected by two gases, i.e., CO and NO, are stored in a warehouse, concentration monitoring needs to be performed on the two gases during the storage of the goods, 5 CO concentration sensors and 5 NO concentration sensors are arranged in the warehouse in parallel, and since the concentration values of the same gas at each position in the warehouse at the same time are the same, the average value of the CO concentrations monitored by the 5 CO concentration sensors is taken as the CO concentration judgment value of all areas in the warehouse; the average value of the NO concentrations monitored by the 5 NO concentration sensors was also taken as the NO concentration judgment value for all the areas of the warehouse. And comparing the CO concentration judgment value and the NO concentration judgment value with preset corresponding CO concentration threshold values and NO concentration threshold values, and judging whether the goods are safely stored. By analogy, when the gas influencing the goods still has other types, the appropriate concentration sensors are selected corresponding to the gas types, the sensors are uniformly arranged in the warehouse, and the gas concentration detection average value of all the sensors of the same type is taken as the concentration judgment value of the gas. The problem of overlarge measurement error of a single sensor can be effectively avoided by the method of averaging the monitoring values of a plurality of sensors, and the accuracy of monitoring the concentration of the marker gas is ensured.
