Description
Technical field
The present invention relates to the detection alarm fields of solid harmful influence and liquid chemicals, liquid combustible and explosive articles, especially
It is related to solid harmful influence Container Transport process and detection alarm system and liquid chemicals, liquid inflammable and explosive substances in storage
The canned detection alarm system during transportation of product.
Background technique
With the development and progress of society, Material Transportation is increasingly shown important, and wherein solid harmful influence is usually to use packaging
Case transports.Shipment and storage during being readily transported due to container consistency, Container Transport have become modernization fortune
Defeated important way.Dangerous chemical Container Transport be contemporary dangerous chemical long-distance transportation one kind it is convenient and
Common mode.But for dangerous chemical, the closure of container constrains fortune during transportational process and storage
Defeated administrative staff unpack and security control.It is not detect alarm setting in this entire transportational process, still
During transportation according to the variation of environment or its be knocked situations such as occur when, the solid harmful influence in container may be sent out
Raw volatilization can cause immeasurable security risk to personnel or environment if such case occurs.Also, transport solid danger
The container of change product is not dedicated tool, i.e., container may transport other articles, therefore on existing container not
There is corresponding detection warning device.
Although existing liquid chemicals, liquid combustible and explosive articles are potted in storage setting and generally have accordingly
Warning device is detected, but is not provided in the canned transportational process of entire liquid chemicals, liquid combustible and explosive articles corresponding
Detection warning device, to entire transportational process, there are corresponding security risks.
A kind of portable wireless gas detecting and alarming instrument control method is disclosed application No. is 201210278442.3,
Belong to warning device software control part；Since the thought of the method for program use is that Portable type gas detection alarm instrument is same
Receiving end configured separate by sound, light and wirelessly transmits warning message, under the guidance of this method, in yard
In may cause danger each position of operating condition certain wireless portable gas detecting and alarming instrument is set, and be that each worker matches
Standby a set of receiving end, in this way, ensure that the alarm that can issue dangerous working condition to all workers in real time when dangerous working condition occurs,
Guarantee the life security of all workers.It is proposed in this scenario by alarm and receives isolated theory, other theories are not necessarily
It is applicable in the transport field of dangerous chemical.
A kind of gas detecting system and gas detection method are disclosed in the patent application No. is 201010624593.0,
The gas detecting system includes gas measurement device and computer installation.Wherein, gas measurement device includes cavity, at least a light
Source, at least a persuader, processor and connection port, computer installation include engagement port and arithmetic unit, and connection port is electrical
Connection engagement port.Cavity includes gas chamber and at least one opening, and opening is connected to gas chamber with external environment.Arithmetic unit is through controlling journey
At least one control signal is exported after sequence, processor emits beam according to control signal control light source and makes persuader output sensing letter
Number to processor, processor is according to sensing signal output characteristics value to computer installation.Therefore, computer installation can be by control
The output of signal controls and starts gas measurement device, to carry out gas detection.The detector can be used for some gases
Detection system in, but cannot be found as early as possible and the problems such as alarm for still remaining in hazardous gas transportational process.
For this purpose, disclose a kind of mobile detection alarm system in 201210240869.4, mainly by gas detecting system,
And it is constituted with the sequentially connected information transmission system of gas detecting system, alarm system.This system is to realize that harmful influence leaks
Comprehensive detection and environment temperature etc. detection, pass through real time data processing, Realtime Alerts are realized in transmission, application technology means are real
Show the detection of maintenance harmful influence transport umbrella journey, monitoring and tracking and avoids and reduce accident to reduce and avoid the generation of accident
Harm improves the safety and reliability of harmful influence transport.
But above-mentioned scheme does not provide concrete implementation scheme, therefore, there is also below for gas detecting system
Problem:
How in solid harmful influence Container Transport process and storage, liquid chemicals, liquid combustible and explosive articles tank
Dress guarantees its safety during transportation.
Summary of the invention
The purpose of the present invention is to provide a kind of mobile detection alarm systems, to solve in the prior art in solid harmful influence
In Container Transport process and storage, liquid chemicals, liquid combustible and explosive articles it is canned during transportation it cannot be guaranteed that its
The technical issues of safety.
A kind of mobile detection alarm system, in solid harmful influence Container Transport process and/or storage, setting to be put
It sets in the container compartment of solid harmful influence or the memory space of storage solid harmful influence ((illustrates indoor storage under normal circumstances
Should all have alarm, thus this alarm only to container use) in detector and be arranged in container car
Outside compartment/memory space outside reception device, reception device it is detachable by signal transmission is connected to detector,
Detector is explosion-proof box body, in the armored cassette body of detector at least provided with:
One gas sensor assemblies, for detecting whether there is the volatilization gas signal of solid harmful influence；
