Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, this example provides a kind of coach air conditioner car-mounted terminal, comprise: temperature collect module, GPS module, air-conditioner controller, LED module, remote communication module, ECU module and power module, described air-conditioner controller is connected with remote communication module with temperature collect module, power module, GPS module, LED module respectively, described air-conditioner controller is connected with telecommunication terminal by remote communication module, and described remote communication module is connected with ECU module.
Described air-conditioner controller can be microcontroller or single-chip microcomputer etc., described temperature collect module can comprise temperature sensor, described air-conditioner controller gathers the temperature data of passenger vehicle by temperature collect module, then remote management center or background server is sent to by remote communication module, achieve the remote temperature data acquisition to passenger vehicle, realize remote activation and close coach air conditioner, be convenient to manage concentratedly and remote monitoring coach air conditioner, facilitate the effects of energy saving and emission reduction of coach air conditioner, drop into little, instant effect, simultaneously because facilitate the long-range unified management to coach air conditioner, the serviceable life of coach air conditioner can also be extended.
Described LED module comprises vehicle-mounted LED display screen, this example realizes LED information issuing system by LED module, and by the expansion of ECU module practical function, described ECU module is vehicle-mounted computer module, i.e. Electronic Control Unit module, described ECU module also detects for realizing ECU; Described air-conditioner controller realizes vehicle location by GPS module and follows the tracks of, be convenient to comprehensive driving recording and vehicle location is managed concentratedly passenger vehicle and coach air conditioner, and then achieve the functions such as remote thermal car and remote alarms, GPS function and the LED information issuing function of automobile can be expanded, realize the functions such as automobile remote diagnostic.
This example also comprises GPS external antenna, GPRS external antenna and SIM card, and described GPS external antenna is connected with GPS module; Described remote communication module is GPRS module, and described GPRS external antenna is connected with GPRS module; Described SIM card is connected with air-conditioner controller.
The setting of described GPS external antenna and GPRS external antenna, be convenient to conveniently receive gps signal and air GPS signal, the installation environment of described coach air conditioner car-mounted terminal should away from the larger and moist environment of thermal value, preferably select breezy place, therefore, preferably, described coach air conditioner car-mounted terminal also comprises moisture-proof case, described moisture-proof case is provided with radiator window and air vent, described radiator window and air vent are all provided with waterproofing design, as being provided with waterproof ventilated membrane; Described SIM card is Subscriber Identity Module client identification module, for identifying the Intelligent Recognition card of user identity, be convenient to each passenger vehicle corresponding with a coach air conditioner car-mounted terminal, have identity code one to one, be convenient to centralized management.
The development of wireless communication technique is with rapid changepl. never-ending changes and improvements, and from beeper radio call to Personal Handyphone System, then to 2G, 3G, will enter the epoch of 4G, current 2G still accounts for main flow at once, because 3G and 4G is also the lifting of data volume.In the 2G epoch, data class service also has dividing of GPRS and CDMA, namely usual said 2.5G, arrive 3G and have TDMA, CDMA2000, WCDMA distinguishes, large operator of state three is called the turn in China, except China Telecom is except operation CDMA, there are support GPRS network in other China Mobile and CHINAUNICOM, and the communication module of current support GPRS network be also do many, GPRS network is also the most stable at present, GPRS is General Packet Radio Service english abbreviation, meaning and GPRS (General Packet Radio Service), it is a kind of wireless, packet-switched technology based on gsm system, there is provided end to end, the wireless IP of wide area connects.Generally, GPRS is the technology of a high-speed data process, and method transmits data to user on hand with the form of " grouping ".If it is in fact also very easy certainly to want to change on other networks, only need the communication module that change is relevant, what preferably adopt in the present system is GPRS network.
GPRS utilizes the Radio Network System of operator's maturation to carry out data transmission, and reliability, the security of therefore its data transmission are all guaranteed; So long as not GPRS blind area (noting: be not mobile phone signal blind area), these two kinds of modes can be adopted to transmit; These two kinds of transmission modes belong to slow data transmission, and real-time can ensure substantially in level second, require that server end preferably has fixing IP or mobile special line, otherwise will adopt dynamic territory analyzing.
This example adopts GPRS mode to possess following features: good real-time response and processing power; Compare with Short Message Service, because GPRS has real-time online characteristic, system is without time delay, the various data of multiple/all vehicle can simultaneously be collected, process to system in real time, just the clock of synchronous each vehicle can well can meet system to data acquisition and the requirement transmitting real-time without the need to taking turn.
Remote Device Control: owing to adopting GPRS bidirectional transmission system, background server and/or Surveillance center oppositely can realize the functions such as time adjustment to vehicle arrangement, status report, switch and other monitoring, control; Can make full use of existing GPRS network, equipment is installed and is namely connected, and construction cost is low; Installation and Debugging are simple, and the construction period is short: utilize existing ripe GSM network, substantially will debug, install simple and direct when system puts into operation.
Wide coverage, build vehicle-state long distance control system and require data communication wide coverage, dilatation is unrestricted, and access place is unrestricted; Because vehicle fleet size is numerous, be distributed within the scope of the whole city, and geographic position dispersion; Adopt GPRS mode, in theory within the coverage of wireless GSM/GPRS network, monitoring can be realized.
Message transmission rate is high, and GPRS network delivery rate can reach 171.2kbit/s in theory, and during practical application, message transmission rate is at about 40Kbps; Communication expense is economical and practical, due to GPRS adopt bag year/mode of monthly payment charging, operation maintenance cost is economical and practical.
