The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of circuit for the substation equipment Temperature sampler of the present utility model.
Embodiment
Refer to Fig. 1, inventor of the present utility model is in order to be understood the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
Refer to Fig. 1, a kind of circuit for the substation equipment Temperature sampler of the present utility model, comprise and be arranged in ZigBee-network processor 1, temperature sensor 2, battery 3, antenna 4, clock circuit 5 and a storage chip 6 on circuit board 9.
Wherein, temperature sensor 2, antenna 4, clock circuit 5 and storage chip 6 all are connected with ZigBee-network processor 1.Battery 3 connects clock circuit 5 and temperature sensor 2.Clock circuit 5 also connects storage chip 6 and temperature sensor 2.
In the present embodiment, what temperature sensor 2 adopted is TMP112 type temperature sensor, for the temperature to substation equipment, is measured.The integrated degree of TMP112 type temperature sensor is high, is easy to be encapsulated on circuit board 9 surfaces.Simultaneously, TM112 type temperature sensor is highly sensitive, and high to the accuracy of the temperature acquisition of substation equipment, the positive and negative deviation of the temperature of collection is less than 1 ℃, and high to the resolution of the temperature acquisition of substation equipment, resolution is 0.1 ℃.
In the present embodiment, temperature sensor 2 and ZigBee-network processor 1 all are provided with the IO interface, so temperature sensor 2 and ZigBee-network processor 1 can communicate and be electrically connected by the IO bus.Certainly, temperature sensor 2 and ZigBee-network processor 1 also can all be provided with the I2C interface, make temperature sensor 2 and ZigBee-network processor 1 communicate and to be electrically connected by the I2C bus.No matter adopt the IO bus or the I2C bus communicates, all have speed fast, the advantage such as the bit error rate is low, cost is few, be suitable for using in the substation equipment Temperature sampler.
In the present embodiment, the ZigBee-network processor 1 adopted is CC2530 type ZigBee-network processor, CC2530 type ZigBee-network processor have the response and toggle speed fast, be easy to carry out the characteristics such as remote debugging, extremely be applicable in the substation equipment Temperature sampler.The CC2530 type ZigBee-network processor adopted in the present embodiment is provided by Omron Corp.
In the present embodiment, the transmission frequency of the antenna 4 of employing is 2.4GHz.Adopt the reason of the transmission frequency of 2.4GHz to be: 2.4GHZ exempts from license, near radio frequency range, and emissive power is little, guarantees substation equipment self-security in transformer station.And not in same frequency range, improved the correctness of the temperature information transmission of substation equipment with carrier wave.
In the present embodiment, the battery of employing is the AA high-temperature battery, and the serviceable life of battery is between-40～120 ℃.
In order to extend the serviceable life of battery 3 and substation equipment Temperature sampler, a kind of circuit for the substation equipment Temperature sampler of the present utility model is generally in the dormancy transition, a kind of circuit for the substation equipment Temperature sampler of the present utility model is when dormant state, the power supply of only having clock circuit 5 and storage chip 6 to receive from battery 3, with the normal operation of assurance clock circuit 5 and the information of storage chip 6, do not lose, wherein, storage chip 6 is electrically connected with clock circuit 5, storage chip 6 receives the power supply from battery 3 indirectly by clock circuit 5.
When full 10 minutes of clock circuit 5 timing, to temperature sensor 2, send the pulse signal of a high level, temperature sensor 2 starts to receive the power supply of battery 3.Owing to connecting by the IO bus or the connection of I2C bus between temperature sensor 2 and ZigBee-network processor 1, this is electric connection, it is also communication connection, ZigBee-network processor 1 is by temperature sensor 2, indirectly receive the power supply from battery 3, a kind of circuit for the substation equipment Temperature sampler of the present utility model is activated.A kind of circuit for the substation equipment Temperature sampler of the present utility model carries out regular measurement according to predefined parameter to the temperature of substation equipment, has realized the technical purpose that extends the serviceable life of battery 3 and whole substation equipment Temperature sampler.
In the present embodiment, ZigBee-network processor 1 is built-in with comparer 11, cache chip 12 sum counters 13.Wherein comparer 11 connects antenna 4, counter 13, storage chip 6 and cache chip 12, and the threshold temperature that the built-in ZigBee-network processor 1 of cache chip 12 is reported to the police, be called for short threshold temperature.
Comparer 11 compares the temperature of substation equipment and threshold temperature, if the temperature of substation equipment lower than threshold temperature, comparer 11 is deposited the temperature of substation equipment in storage chip 6, the counting of unison counter adds 1.Then, clock circuit 5 sends a low level pulse signal again, and temperature sensor 2 terminating receptions are from the power supply of battery 3.
When counter 13 be counted as 3 the time, antenna 4 starts, comparer 13, from storage chip 6, reads the temperature information that gathers substation equipments for three times, by antenna 4, sends together the central coordinator (not shown) to.Then, counter 13 zero clearings.Simultaneously, clock circuit 5 sends a low level pulse signal, and temperature sensor 2 terminating receptions are from the power supply of battery 3.
Such design, transformer station's Temperature sampler, within 30 minutes, upload the temperature information of one time power transformation station equipment, the power consumption that has reduced the temperature information of antenna 4 frequent transmission substation equipments and produced, further reach the technical purpose in the serviceable life that extends battery 3 and whole substation equipment Temperature sampler.
If the temperature of substation equipment is higher than threshold temperature, comparer 11 generates temperature alarming information, and starts immediately antenna 4, by antenna 4, sends described central coordinator to.Temperature alarming information comprises temperature, position, time and the information warning of substation equipment.Being designed with like this helps reduce because produced accident and loss are reported and failed to report to the information of substation equipment excess Temperature late.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and not be used as restriction of the present utility model, as long as in connotation scope of the present utility model, to variation, the modification of the above embodiment, all will drop in claims scope of the present utility model.
