The utility model is achieved through the following technical solutions:

Based on the wireless clock system of wireless senser, its special character is to comprise master clock system, secondary clock system, wireless relay system, and the three connects by the 8 mutual communications of ZigBee wireless network;

Described master clock system comprises the time source device 1 that is used to produce and provide split-second precision information, time source device 1 passes through RS422 or RS485 or CAN bus and is connected with master clock 2 communications, master clock 2 is coordinated converter 7 communications by RS422 or RS485 or CAN bus with the ZigBee master clock and is connected, and master clock 2 passes through RS422 or RS485 or CAN bus or RS232 bus and monitors webmaster 3 communications and be connected;

Described secondary clock system comprises ZigBee secondary clock terminal converter 4 and by RS422 or RS485 or CAN bus terminal secondary clock 5 interconnective with it;

Described wireless relay system comprises the safe and effective ZigBee router 6 that couples together of wireless signal that is used for 5 of master clock 2 and terminal secondary clocks;

After time source receiving trap 1 receives or is synchronized with the standard time, begin to produce and provide high precision time information, pass to master clock 2 by RS422 or RS485 or CAN bus, master clock 2 is synchronized with time source, then periodically RS422 or RS485 or CAN bus time, signal passes to the ZigBee master clock and coordinates converter 7, the ZigBee master clock is coordinated converter 7 and by network time reference signal is imported in the ZigBee wireless network 8 by wireless, for other ZigBee router 6 and ZigBee terminal device (secondary clock system) provide the standard time packet, the secondary clock system is by calculating, finally be synchronized with time source, also the pass through RS422 or RS485 or CAN bus of all period interval pass to the various status informations that the ZigBee master clock coordinates to gather in the converter 7 access ZigBee wireless networks 8 the secondary clock system to master clock 2 simultaneously, and then be connected with monitoring webmaster 3 by RS422 or RS485 or CAN bus, communication mutually, thereby reach real-time remote monitoring, safeguard the effect of princip al and subordinate clock system.

The utility model is based on the wireless clock system of wireless senser, reasonable in design, based on the ZigBee radio sensing network, need not wiring, install, need not destroy the outward appearance of buildings, by wireless princip al and subordinate clock system based on the ZigBee radio sensing network, utilize the analysis of ZigBee wireless technology and routing algorithm thereof, need not manual intervention, the existence of other node of network node energy perception, and definite annexation, form structurized network, can be to the increase of its node, deletion or move, network can be repaired automatically when node broke down, need not manual intervention, guarantee the normal operation of total system, more help network management, control and maintenance.Be convenient to the center and manage, control, safeguard, failure message is analyzed with the fastest speed, draw best solution, safeguard in long-range unification.

Embodiment

Provide embodiment of the present utility model below with reference to accompanying drawing, be used for formation of the present utility model is described further.

Embodiment 1

The wireless clock system based on wireless senser of present embodiment comprises master clock system, secondary clock system, wireless relay system, and the three connects by the 8 mutual communications of ZigBee wireless network; The master clock system comprises the time source device 1 that is used to produce and provide split-second precision information, time source device 1 passes through RS422 or RS485 or CAN bus and is connected with master clock 2 communications, master clock 2 is coordinated the converter communication by RS422 or RS485 or CAN bus with the ZigBee master clock and is connected, and master clock 2 passes through RS422 or RS485 or CAN bus or RS232 bus and monitors webmaster 3 communications and be connected; The secondary clock system comprises ZigBee secondary clock terminal converter 4 and passes through RS422 or RS485 or CAN bus terminal secondary clock 5 interconnective with it; Wireless relay system comprises the safe and effective a plurality of ZigBee routers 6 that couple together of wireless signal that are used for 5 of master clock 2 and terminal secondary clocks.

Principle of work: the time source device 1 of master clock system is by GPS or big-dipper satellite acceptance criteria time signal, produce high-precision RS422 or RS485 or CAN time signal then, per second down sends, after being synchronized with time source after master clock 2 is received, coordinate converter 7 as the center by the ZigBee master clock again, after will receiving RS422 or RS485 or CAN time signal, time signal is packaged into the ZigBee wireless data packet, toward ZigBee wireless network 8 broadcast transmissions, simultaneously also coordinate converter 7 as required and send relevant operational order, simultaneously the information that feeds back is changed into RS232 and the 3 mutual communications of monitoring webmaster by RS422 or RS485 or CAN by the ZigBee master clock at each gap periods master clock.The ZigBee secondary clock terminal converter 4 of secondary clock system, collect the ZigBee master clock in real time and coordinate the signal that converter 7 broadcasting are come, the signal that directly changes into RS422 or RS485 or CAN sends to terminal secondary clock 5, terminal secondary clock 5 is according to different data service operations, as be synchronized with time source, perhaps return state information is perhaps carried out a certain instruction etc.The ZigBee router 6 of relay system is by the ZigBee wireless network, center and internodal information are transmitted according to optimal path, such as the secondary clock far away with respect to distance, the ZigBee master clock is coordinated converter 7 data is broadcast to ZigBee router 6 earlier, be broadcast to ZigBee secondary clock terminal converter 4 by ZigBee router 6 again, make network healthy and strong more.

The wireless clock signal based on wireless senser of present embodiment, influenced by civil engineering and wiring at cable in the prior art as transmission medium, present embodiment uses based on ZigBee wireless network 8, then need not wiring, install, need not destroy the outward appearance of buildings, after the original system business must being suspended in the prior art, again the situation of group net operation after connect improving, the present invention can be by the wireless princip al and subordinate clock system based on ZigBee wireless network 8, utilize the analysis of ZigBee wireless technology and routing algorithm thereof, need not manual intervention, the existence of other node of network node energy perception, and definite annexation, form structurized network, can be to the increase of its node, deletion or mobile.Network can be repaired automatically when node broke down, need not manual intervention, guarantee the normal operation of total system, and more help network management, control and maintenance.Being convenient to the center manages, controls, safeguards in long-range unification.Failure message is analyzed with the fastest speed, drawn best solution, safeguard.
