Description of drawings
Accompanying drawing is an electrical schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
The vibratory string readout instrument comprises power supply, parameter setting, sensor data acquisition, cpu data processing and storage, data presentation and output, temperature measuring equipment, the temperature alarming device of prior art, and present embodiment is to be connected the heat sink of heating at the contact place of the signal input of the signal output contact place of temperature measuring equipment and temperature alarming device.
The heat contact place of signal input of the coil J1 of one-way switch K1 of heat sink and temperature alarming device is connected to form the loop, the signal output contact place of the coil J2 of selector switch K2 and temperature measuring equipment is connected to form the loop, one-way switch K1 and selector switch K2 series connection, the normally closed contact of selector switch K2 and heat sink M connect and compose the loop, and the normally opened contact of selector switch K2 connects and composes the loop with the element R that heats.
One-way switch K1 and coil J1 thereof, selector switch K2 and coil J2 thereof can adopt controllable silicon or other contactless electronic beam switch circuit to realize.The element R that heats of present embodiment is the heating resistor that dries.Heat sink M is an electric fan.
Heat the operating mode of heat sink fully by the control of automatic identification commutation circuit, without any need for extra operation.Operating mode discern automatically commutation circuit mainly by one-way switch K1 and coil J1 thereof and selector switch K2 and and two groups of on-off circuits of coil J2 carry out, one-way switch K1 and coil J1 thereof are by the signal S control of the contact of the signal input of temperature alarming device, selector switch K2 and coil J2 thereof are controlled by the low temperature decision circuitry by the signal T of the signal output contact of temperature measuring equipment, and the heat sink of will heating at last switches heating, lower the temperature and wait in three kinds of duties automatically.For example, the high-temperature T of alarm temperature is set to 30 ℃, and low temperature TL is set to 10 ℃, and the judgment standard temperature T s in the low temperature decision circuitry is set to 20 ℃, then:
1, wait for operating mode: environment temperature is between 10 ℃ and 30 ℃, and S does not have signal, and one-way switch K1 is in off-state.
2, the operating mode of heating: environment temperature is at 10 ℃ or when following, and S has signal, and coil J1 connects, one-way switch K1 closure; In the time of T10 ℃, the S signal stops, and coil J1 does not have electricity, and one-way switch K1 disconnects; Simultaneously, it is not low temperature that the low temperature decision circuitry is judged, cuts off the resistive heating circuit that dries and stops to heat, and enters the wait operating mode.
3, cooling operating mode: environment temperature is at 30 ℃ or when above, and S has signal, and coil J1 connects, one-way switch K1 closure; T＞Ts, it is not low temperature that the low temperature decision circuitry is judged, disconnects coil 2, directly starts the electric fan cooling; When T＜30 ℃, the S signal stops, and coil J1 does not have electricity, and one-way switch K1 disconnects, and electric fan quits work, and enters the wait operating mode.
Environment self-adaption formula intelligence vibratory string readout instrument of the present utility model both can be worked under cryogenic conditions, can also work in high temperature, and be identification automatically and selection working condition.
