Abstract
The utility model discloses a real time monitoring system of transformer substation overhauling device ground state, comprising a computer and a coordinator. At least one coordinator is connected with the computer by a serial interface. Each coordinator is connected with at least two node detecting devices. The utility model adopting the technical proposal can detect and display the ground state of each place intensively, based on zigbee wireless LAN technology. The utility model can reduce the serious accidents without the need of wiring and changing operation regulations.
Description
Technical field
The utility model belongs to safety protection equipment, relates in particular to a kind of transformer station repair apparatus ground state real-time monitoring system.
Background technology
When on power circuit, carrying out service work, must be earlier with maintenance line outage, at the job site two ends and might send electricity hanging earthing conductor to the branch line of dead line, or closed ground connection disconnecting link, make the electrical equipment that is overhauled be in safe current potential all the time, prevent that incoming call damages staff and equipment suddenly.But after service work finishes; disconnect the ground connection disconnecting link as if forgetting to remove the ground wire that articulates or forget, then when circuit send electricity, will cause the direct ground connection of system's three-phase, thereby cause female protection action that joins owing to staff's carelessness; form large-area power-cuts, bring about great losses.Therefore, the insider is often arranged with the ground connection disconnecting link with articulate temporary ground wire and be referred to as one " merciless double-edged sword ", they are requisite safety precautions in high-tension distribution equipment and the line maintenance process, if but operate mishandling, again may the serious harm electric system and the safe operation of equipment.
Summary of the invention
The purpose of this utility model provides a kind of transformer station repair apparatus ground state real-time monitoring system, and this system is based on the zigbee wlan technologies, can detect, centralized displaying each point ground state, can effectively reduce the hidden danger that serious accident takes place.
For achieving the above object, the utility model adopts following technical scheme: a kind of transformer station repair apparatus ground state real-time monitoring system, comprise computing machine, at least one telegon links to each other by serial line interface with computing machine, and each telegon links to each other with two node detection devices at least.
Each telegon links to each other with a router at least, and each router links to each other with two node detection devices at least.
Be connected based on the zigbee WLAN (wireless local area network) between telegon and the node detection device.
Between telegon and the router, all be connected between router and the node detection device based on the zigbee WLAN (wireless local area network).
Described telegon comprises a wireless singlechip, and wireless singlechip links to each other with Switching Power Supply.
Described router comprises a wireless singlechip, and wireless singlechip links to each other with Switching Power Supply.
Described node detection device comprises a wireless singlechip, and wireless singlechip links to each other with chargeable battery, and ground detection device also links to each other with wireless singlechip.
Adopt transformer station's repair apparatus ground state real-time monitoring system of technique scheme, based on the zigbee wlan technologies, can detect, centralized displaying each point ground state, need not wiring, need not to change working specification, can effectively reduce the hidden danger that serious accident takes place.

Embodiment
Transformer station's repair apparatus ground state real-time monitoring system as shown in Figure 1 comprises computing machine, and a telegon links to each other by serial line interface with computing machine, and as shown in Figure 2, telegon comprises a wireless singlechip, and wireless singlechip links to each other with Switching Power Supply.Telegon is connected based on the zigbee WLAN (wireless local area network) with two node detection devices at least, and as shown in Figure 4, the node detection device comprises a wireless singlechip, and wireless singlechip links to each other with chargeable battery, and ground detection device also links to each other with wireless singlechip.Telegon also is connected based on the zigbee WLAN (wireless local area network) with a router, and as shown in Figure 3, router comprises a wireless singlechip, and wireless singlechip links to each other with Switching Power Supply.Router is connected based on the zigbee WLAN (wireless local area network) with two node detection devices at least.
In practical operation, computing machine can connect a plurality of telegons by serial line interface, and each telegon also can be handled the data of a plurality of routers.Used wireless singlechip is selected CC2430 for use.Telegon, router need mains supply.Then by the ferric phosphate lithium cell power supply, battery is dismountable with finishing for each node detection device.As the auxiliary device of necessity, system disposition has special-purpose ferric phosphate lithium cell charging set.
In each detection node, adopt two main elements in the ground detection device: microswitch and toggle switch.Whether microswitch is used to detect local earthing device ground connection; Toggle switch produces the group alias of this earth point by various combination.Ground detection device links to each other with wireless singlechip by a multi-pin connector.It is the retrieval charging that wireless singlechip uses up, and this ground detection device then can forever be installed on each earth point.
By the installation site of suitable selection router, the ultimate range between detection node and the router can be controlled in 150 meters, thereby the may command emissive power reduces energy consumption.
Principle of work of the present utility model is as follows:
When movably the node detection device is placed in some earth points temporarily and is entered duty, can detect the information such as ground state, group of this point, for from the nearer detection node of telegon, can directly send information to telegon, and the detection node far away of adjusting the distance, then earlier send information to router, and and then send information to telegon by router.
Computing machine is to the acquisition of each point ground state, by realizing with the serial communication of telegon.
Computer user interface adopts the VB6.0 visual program design language to design and develop, and in real time, dynamically shows the state of each earth point, generates form, sound and light alarm etc.
