A kind of novel power equipment is patrolled and examined handheld terminal
Technical field
The present invention relates to a kind of novel power equipment and patrol and examine handheld terminal.
Background technology
The polling transmission line management system > > 201020212496.6 of Chinese patent document < < based on RFID technology discloses a kind of power circuit polling terminal, comprise rfid interrogator, microprocessor, wireless communication module (can adopt the modes such as GSM, GPRS) etc.
But because its wireless communication module is generally only selected a kind of wireless network (GPRS, GPS etc.), when adopted GPRS, due to electric system, to patrol and examine scope wide, and a lot of regions may not have GPRS to cover, and so just cannot guarantee uploading in time of data.Meanwhile, it comprises rfid interrogator, and patrol officer need be scanned rfid card one by one, easily omit, and in card, data volume is less, for the electric and environmental information of the switch on shaft tower, transformer equipment monitoring, cannot collect, and increases patrolman's work difficulty.
Summary of the invention
The object of this invention is to provide a kind of power equipment based on wireless self-networking and GPRS/TD-LTE and patrol and examine handheld terminal, in order to solve when distribution line is patrolled and examined difficulty and single wireless network existence covering blind spot, cannot guarantee the problem that data are uploaded in time.
For achieving the above object, the solution of the present invention comprises:
A kind of novel power equipment is patrolled and examined handheld terminal, comprise that microprocessor and power module, microprocessor are connected with input-output device, wireless self-networking module, RFID identification module and wireless communication module, patrol officer patrols and examines by the route of prior setting, pass through sensor Ad Hoc network, active obtaining information, safe and reliablely upload fast, described wireless communication module at least comprises GPRS wireless public network communication module and TD-LTE wireless private network communication module.
Microprocessor is also connected with for the communication module of wireless self-networking and RFID scan module, can set patrol officer's the route of patrolling and examining, the electric and environmental information of active obtaining power equipment.
Between described GPRS wireless public network communication module and TD-LTE wireless private network communication module, it is physical isolation.
Microprocessor is also connected with the switching button for operate wireless public network and wireless private network conversion.
Described input-output device is touch-screen.
The present invention has increased wireless self-networking module, and the electric and environmental monitoring information of active obtaining controller switching equipment has alleviated patrol officer's the difficulty of patrolling and examining; By RFID scan module, set patrol officer's patrol route simultaneously, realize equipment control and supervision inspection route; Increased TD-LTE wireless private network communication module, TD-LTE transmission is separate with GPRS transmission, has played the effect of redundancy.When GPRS network unavailable, and TD-LTE network is when available, be transformed into TD-LTE wireless private network communication mode and complete data upload business, when TD-LTE network unavailable, and GPRS network is when available, be transformed into GPRS wireless private network communication mode and complete data upload business, guarantee also to have guaranteed when data are uploaded in time the safety of electric power system data.
Between GPRS wireless public network transport module and TD-LTE transport module, need strict physical isolation.By switching button, realize two conversions between network, make operating personnel can manually select TD-LTE and GPRS network to transmit.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
The power equipment of a kind of GPRS/TD-LTE based on wireless self-networking is is as shown in Figure 1 patrolled and examined handheld terminal, comprise that microprocessor and power module, microprocessor are connected with input-output device, wireless self-networking module, RFID identification module and wireless communication module, wireless communication module at least comprises GPRS wireless public network communication module and TD-LTE wireless private network communication module.Input-output device can adopt keyboard display or touch-screen.
Patrol officer arrives behind the scene of patrolling and examining by hand-held mobile terminal, by wireless self-networking module, obtains the electric and environmental information of Distribution Network Equipment operation; By scanning RFID bar code, supervision patrol officer's patrol route; According to on-site actual situations, select GPRS wireless public network communication mode or TD-LTE wireless private network communication mode that information is sent to system main website; According to the requirement of electric system secondary safety protection system, between GPRS wireless public network communication module and TD-LTE wireless private network communication module, should have strict physical isolation measure, and the two can not communicate simultaneously.
Electric power secondary system security protection is complicated systems engineering, and its overall safety protection level depends in system the security level of thin spot, and therefore, during public network access, security protection is even more important.As shown in Figure 2, first GPRS wireless public network communication module is netted by state the cryptographic algorithm pushing away of uniting and is encrypted reinforcing, and then by GPRS wireless network access security access platform, after security platform is confirmed, information just can arrive main station system.And the information of TD-LTE private network transmission can directly be delivered to system main website.
Patrol officer is after obtaining the electric and environmental information of controller switching equipment, and system provides the prompting of optimal network, by the control of switching button, selects optimum communication mode, realizes the safe and reliable of information and uploads fast.
Each ingredient of the terminal the present invention relates to, as wireless self-networking module, GPRS wireless public network communication module and TD-LTE wireless private network communication module etc. all belong to prior art, does not repeat them here.
