RFID hospital equipment wireless temperature measurement

Due to the particularity of the work of the Hospital, the quality of the power supply environment has put forward special and strict requirements for the safety of the hospital's power supply. How to predict the common faults of hospital power supply system and improve the reliability of power supply will be more and more concerned by hospital administrators and electrical management and maintenance personnel. Only through long-term efforts can we continuously improve the reliability of hospital power supply and do a good job in hospital logistics support.

The hospital is an important place to save lives and heal the wounded. Overloading of various electrical equipment may lead to power outages, interruption of ongoing operations, death of cultured cells and other serious consequences, which will bring great losses to hospitals and patients.

Install wireless temperature measurement online monitoring system for high and low voltage power distribution equipment in power distribution room

The hospital introduces wireless temperature measurement devices, and installs wireless temperature measurement sensors on the busbars, cable heads, and electrical contacts in the electrical equipment of the power distribution room, and leads the monitored temperature data to the power distribution duty room. The electrical duty room can monitor the electrical contact temperature data of the power transformation and distribution equipment in real time. Once the temperature of the equipment is abnormal, the wireless temperature measurement system will immediately send out an alarm sound, and the on-duty staff can find out immediately and take measures to ensure the safety of the hospital's power supply. The temperature measurement and monitoring system Stores these operating data in the computer in real time, which can also be used as a basis for future operation analysis, and also provides data support for the daily operation and maintenance of hospital electrical equipment.

The RFID wireless temperature measurement system can provide different wireless temperature measurement solutions according to the complex distribution network of the hospital, and monitor the temperature of the electrical equipment itself in real time. Wireless communication is usually used in conjunction with receiving terminals, communication serial ports, and electronic computers. The wireless temperature measurement sensor transmits temperature data to the wireless temperature measurement centralized acquisition host through RFID technology, and then uploads the data to the wireless temperature measurement system through different communication channels. It is suitable for a variety of special measurement and control occasions such as outdoors, high temperature, humidity, dust, high voltage, inconvenient wiring, or power supply that cannot be provided on site. The system solves the cost of on-site installation and wiring, overcomes the influence of the complex installation environment, and realizes the real-time online monitoring of the temperature of the electrical equipment itself.

RIFD radio frequency identification technology uses radio wave non-contact fast information exchange and storage technology, combined with data access technology through wireless communication, and then connects to the database system to achieve non-contact two-way communication, thus achieving the purpose of identification for data exchange , connecting an extremely complex system in series. In the identification system, the reading, writing and communication of electronic tags are realized through electromagnetic waves. According to the communication distance, it can be divided into near-field and far-field. For this reason, the data exchange method between the read/write device and the electronic tag is also correspondingly divided into load modulation and backscatter modulation.

A complete RFID system consists of three parts: Reader, Tag and data management system.

A high-precision ultra-low power consumption (1 microwatt) temperature sensor chip is embedded on the traditional RFID chip, and a built-in 512-bit erasable non-volatile data storage unit is used to store user information and other data. The communication interface of the RF chip supports the EPC Global C1G2 v1.2 communication interface protocol. When reading the chip, the user can not only obtain the ordinary ID number, but also obtain real-time temperature information. The measurement range can reach -40 to +125 degrees Celsius. The error is 1 degree after single-point calibration at room temperature, and the error can be less than 0.1 degrees when it is between 35 and 42 degrees Celsius. The chip has good consistency.
