Embodiment
LNG tank case supervisory system in a kind of railway transport course, LNG tank case is fixedly mounted on the car body of transportation LNG tank case, LNG tank box top is the metal top plate of punching, LNG tank case afterbody is the control box of sealing, a car group arranges Yi Ge Surveillance center, and Surveillance center arranges monitor terminal and data receiver; The pressure, the Level meter table that in control box, have LNG tank case, measuring instrument connection data transmission equipment, transmission equipment is by the data receiver of wired or wireless link connection Surveillance center.
The transmission of data can adopt wired mode and wireless mode.Adopt wired mode not affected by environment, but need on car body, increase cable connector, between car body, use cable to connect, therefore we adopt wireless transmission system, in order to prevent broken by lightning equipment, in system, use lightning protection device, the earth terminal of lightning protection device is connected on LNG tank case or car body.
Between LNG tank case and monitoring car, there is isolation lorry, and the car body that loads LNG tank case is a lot, therefore LNG tank case distance detection spacing is different, again due to circumstance complication in train travelling process, in order to improve the reliability of data transmission, in system, adopt two sets of data receiving equipments, antenna installation is at the diverse location of Surveillance center, and the output of every sets of data receiving equipment is connected to the different input ends of monitor terminal.Because the position that two slave antennas set up is different, when vehicle moves under complex environment, the residing electromagnetic environment of two slave antennas is also different, has so effectively improved the validity and reliability of data transmission.
In wireless transmission, antenna installation position should be tried one's best high.In native system, the antenna installation of wireless instrument is below the metal top plate of LNG tank box top.LNG tank case metal top plate is in most significant end, can regard lightning protection net as, therefore antenna is installed and can not considered especially the problem of lightning protection, in addition because antenna is arranged in LNG tank case, can be because folded sieve of LNG tank case damages antenna in LNG tank case transport process, can not bring inconvenience to the personnel that work on LNG tank case simultaneously yet, and because selected installation site is higher, four sides is more penetrating, little to antenna work influence, in addition, because antenna is installed by antenna pedestal, can install easily, dismantle antenna.
Except pressure and liquid level, other data of relevant LNG tank case are also helpful to the judgement of its safe condition, therefore, increased here and measure the environment temperature of LNG tank case and the measuring instrument of sea level elevation in control box.
In order to make system run all right, reliable, described wireless instrument adopts the instrument of explosion proof ratings, and because this system is to use under train operation environment, therefore described instrument power adopts low temperature resistant lithium battery.
For safety, Surveillance center is located at head or the afterbody of car group, and sets up explosion-proof buffering platform, protects the equipment in Surveillance center when anti-vehicle is handled affairs event.
Technique scheme can solve the monitoring of LNG tank case in a car group, along with the development of Internet of Things, is necessary all LNG tank casees in fortune to carry out Centralized Monitoring.
For achieving the above object, system is set up remote monitoring center, and remote monitoring center arranges supervisory control comuter and radio communication device, and the Surveillance center's correspondence in car group is set up radio communication device and positioning equipment.Initiatively or respond to a call for recruits or candidates monitor data is sent to Surveillance center, Surveillance center can realize the state of all LNG tank casees in fortune of monitoring for Surveillance center in each car group.
The remote data communication generally using is at present to use 3G public network, and its wide coverage, communication speed is fast, expense is low.But consider the singularity of train transportation, likely operate in the backcountry that does not have public network to cover, therefore increase satellite communication equipment supplementing and backup communication means as 3G network.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
